Django is een professioneel raamwerk om internet applicaties mee te bouwen.
\r\nZeker bij complexe applicaties zorgt Django er voor dat het relatief eenvoudig is om snel met resultaten te komen.
\r\nHet mooie is dat belangrijke basisfunctionaliteiten zoals bijvoorbeeld inloggen en registreren al in een app zitten en het eenvoudig wordt om uit te breiden naar uw wensen.
Django of Laravel: Welk framework is het beste in 2022 ? zie https://kinsta.com/nl/blog/django-of-laravel/#django-en-laravel-welk-framework-is-beter-voor-webdevelopment
\r\n\r\nDjango heeft het MVT design structuur ! zie https://www.geeksforgeeks.org/django-project-mvt-structure/
\r\n\r\n2005 : World Online (krant VS) ontwikkelaars Adrian Holovaty en Willison Simon samen met ,Jacob Kaplan-Mosse, Wilson Miner
\r\nPHP gedumpt en Python werd gebruikt voor ontwikkelen van websites ; succes met Lawrence.com
\r\nopen-source software Django genoemd naar Django Reinhardt (in België geboren als Jean Reinhardt 1910-1953 een gipsy jazz muzikant) daar Adrian Holovaty een Am muzikant van jazz , woont nu in Amsterdam...
sedert 1,5 jaar enorm succes ... , nu al aan versie 3.0 (april 3.1, dec 3.2 en eind 2021 4.0)
\r\nMVC raamwerk
\r\nMVC (Model-View-Controller)
\r\nWat is MVC?
\r\nMVC is een software-architectuur ontwerppatroon . Het verdeelt of scheidt uw app in drie delen:
\r\nModel: verantwoordelijk voor gegevensopslag en -beheer,
\r\nView = weergave: verantwoordelijk voor het weergeven en weergeven van de gebruikersinterface
\r\nController: verantwoordelijk voor de afhandeling van logica om de gebruikersinterface te besturen en met het datamodel te werken.
MVT structuur:
\r\n\r\n![\"\"](\"/media/upload/2019/12/25/django1.png\")
\r\nmodel : waar we onze gegevens plaatsen : foto's , video's, titels, namen, beschrijvingen ... datums
\r\nview : hoe je website de gegevens krijgt van onze modellen en voor de gebruikers verwerkt.
\r\ntemplate : de weergave van de gegevens op de website. Bestaande Tools HTML, CSS en Javascript
![\"\"](\"/media/upload/2022/04/12/mtv_drawing1.png\")
![\"\"](\"/media/upload/2019/12/25/django2.png\")
standaard worden een aantal apps automatisch toegevoegd aan het Django Project
\r\n\r\nhet mooie is : een app is herbruikbaar , je kunt dezelfde app in meerdere projecten gebruiken
\r\niedere app : admin.py, models.py, views.py en urls.py (meestal)
object-relational mapper
\r\n\r\nDjango Model : beschrijft je tabel van je database records (in models.py)
\r\n\r\neenvoudige manipulatie van je gegevens zonder complexe SQL re moeten schrijven
\r\nIn de meeste gevallen worden er relaties gelegd tussen je gegevens
een op een (OnetoOne) ; één op veel relatie (OnetoMany) ; veel op veel relatie (ManyToMany)
\r\n\r\n![\"\"](\"/media/upload/2019/12/25/django3.png\")
Django maakt automatisch je tabellen en indexen in je database
\r\n\r\nDjango biedt 4 basisdatabasefuncties : Creëren, lezen, bijwerken en verwijderen
\r\n\r\nCRUD : Create, Read, Update en Delete
\r\n\r\npython API .... application program interface : data in XML formaat of JSON (Java Script Object Notation) formaat
\r\n\r\npython manage.py shell
\r\n\r\nautomatisch gegenereerde admin functie
\r\n\r\neen eenvoudige database kan gebruikt worden : SQLITE3.
\r\n\r\nAlsook MySQL, MariaDB , PostgreSQL Oracle, ... kan gebruikt worden.
\r\n\r\nDjango ondersteuning internationalizering i18n en ondersteuning verschillende tijdzones
\r\n\r\nwebtoepassingen in andere talen : spellingscontrole in het Nederlands
\r\n\r\ntijdzones : nul meridiaan van Greenwich = UTC
\r\n\r\nwij : UTC + 1
\r\n\r\nzie 20 postcodes per pagina ipv 50
\r\n\r\nin pdf formaat : doc in pdf formaat
\r\n\r\npython beschikt over zeer uitgebreide pakketten , je moet hier het wiel niet terug uitvinden meestal zal je hier gebruik kunnen maken van reeds geschreven software
\r\n\r\nvoorbeeld : als de webcam van je laptop wilt gebruiken om qrcodes of streepjescode wilt scannen dan kun je bestaande speciale python pakketten hiervoor gebruiken !
\r\n\r\n\r\n\r\ndatabase
\r\n\r\nstandaard SQLITE3 documentatie : sqlite3 documentatie
\r\n\r\nandere database : MySQL, PostgreSQL, ORACLE, SAP, IBM_DB2, ODBC
\r\n\r\nmeest populaire django websites
\r\n\r\nallerlei formulier widgets zijn mogelijk : 'TextInput', 'NumberInput', 'EmailInput', 'URLInput', 'PasswordInput', 'HiddenInput', 'MultipleHiddenInput', 'FileInput', 'ClearableFileInput', 'Textarea', 'DateInput', 'DateTimeInput', 'TimeInput', 'CheckboxInput', ...
\r\n\r\nkalender
\r\n\r\nbij een datum veld , klik en er komt een maandkalender te voorschijn
\r\n\r\nscrolbaar per dag, maand en jaar
\r\n\r\nvoordeel : onafhankelijk van nieuwere software
\r\n\r\nverschillende tools voor een virtuele omgeving

bootstrap 4.5.0 : zie bootstrap4 tutorial w3schools
\r\n\r\n Voordelen van Bootstrap:
\r\n Eenvoudig in gebruik: iedereen met alleen basiskennis van HTML en CSS kan Bootstrap gaan gebruiken
\r\n Responsieve functies: de CSS van Bootstrap past zich aan op smartphones, tablets en desktops
\r\n Mobile benadering: in Bootstrap : stijlen maken deel uit van het kernraamwerk
\r\n Browsercompatibiliteit: Bootstrap 4 is compatibel met alle moderne browsers (Chrome, Firefox, Internet Explorer 10+, Edge, Safari en Opera)

Welkom op de Adressen administratie site, ontwikkelt met de modernste skeleton web framework = Django.
\r\n Met Django is het mogelijk om vlugger en met minder code Website applicaties te maken.
\r\n Het maakt gebruik van het MVC ontwerppatroon : complexe toepassingen worden ontworpen in drie eenheden = M(Model)-V(View)-C(Controller).
\r\n Het datamodel zit in het Model, de datapresentatie in het View en de applicatielogica in de Controller.
\r\n Het scheiden van deze verantwoordelijkheden bevordert de leesbaarheid en herbruikbaarheid van code.
Het maakt ook dat bijvoorbeeld veranderingen in de gebruikersinterface niet direct invloed hebben op het datamodel en vice versa.
\r\n Het maakt gebruik van de serverloze Sqlite database dmv. de Python programmeertaal.

op het internet wordt data uitgewisselt over het web, meestal wordt het JSON formaat (Java Script Object Notering) gebruikt om gegevens door te spelen
\r\n\r\nweer API met parameters q = stad, units = metric en lang = nl voor nederlands met API key
\r\n\r\ncurl -s 'http://api.openweathermap.org/data/2.5/weather?q=Deerlijk&units=metric&lang=nl&appid=5cf01f009b7d0178a211d460f3ac67d7' | jq
\r\n\r\nIndien Http-response = 200 dan is de stad gevonden met de accuweather API
\r\n\r\nIndien Http-response <> 200 dan is de stad niet gevonden en wordt de foutboodschap : "Stad bestaat niet in deze wereld !" getoond en wordt er geen nieuwe stad ind dedatabase gecreeerd.
\r\n\r\nIndien Stad al in de database zit dan wordt de boodschap : "Stad bestaat reeds in de database !" getoond en wordt er geen nieuwe stad ind dedatabase gecreeerd.
\r\n\r\nPer stad worden de temperatuur, beschrijving, een icoon, de tijdzone en het land getoond.
\r\n\r\nHet json formaat van de gevonden API wordt getoond bij het opstarten van de website.

\r\n\r\n\r\npost.author.id\r\n\r\nIf you have a foreign key named author, Django will automatically store the primary key in the property author_id, while in the author property will be stored a lazy database reference. So if you access the id via the author instance, like this post.author.id, it will cause an additional query.

Dit kan aangepast worden als je in Django admin mode gaat dan kun je Sites aanpassen in de sectie WebSites . .
Dotenv is een manier om geheime sleutels (publieke als secret) en wachtwoorden op te slaan in environment variabelen.
\r\n\r\nDeze worden opgeslagen in een .env bestand. het bestand .gitignore moet het bestand .env bevatten zodat dit bestand niet opgeladen wordt in github dit om te voorkomen dat deze sleutels openbaar worden !

Here we go:
\r\n\r\nIt is generally recommended to use singular nouns for model naming, for example: User, Post, Article. That is, the last component of the name should be a noun, e.g.: Some New Shiny Item. It is correct to use singular numbers when one unit of a model does not contain information about several objects.
\r\n\r\nFor relationships such as ForeignKey, OneToOneKey, ManyToMany it is sometimes better to specify a name. Imagine there is a model called Article, - in which one of the relationships is ForeignKey for model User. If this field contains information about the author of the article, then author will be a more appropriate name than user.
\r\n\r\nIt is reasonable to indicate a related-name in plural as related-name addressing returns queryset. Please, do set adequate related-names. In the majority of cases, the name of the model in plural will be just right. For example:
\r\n\r\nclass Owner(models.Model):
\r\n\r\npass
\r\n\r\nclass Item(models.Model):
\r\n\r\nowner = models.ForeignKey(Owner, related_name='items')
\r\n\r\nThere is no point in using ForeignKey with unique=Trueas there exists OneToOneField for such cases.
\r\n\r\nPreferable attributes and methods order in a model (an empty string between the points).
\r\n\r\nconstants (for choices and other)
\r\nfields of the model
\r\ncustom manager indication
\r\nmeta
\r\ndef unicode (python 2) or def str (python 3)
\r\nother special methods
\r\ndef clean
\r\ndef save
\r\ndef get_absolut_url
\r\nother methods
\r\nPlease note that the given order was taken from documentations and slightly expanded.
If you need to add a model, then, having created a class of a model, execute serially manage.py commands makemigrations and migrate (or use South for Django 1.6 and below).
\r\n\r\nYou should not allow thoughtless use of denormalization in relational databases. Always try to avoid it, except for the cases when you denormalise data consciously for whatever the reason may be (e.g. productivity). If at the stage of database designing you understand that you need to denormalise much of the data, a good option could be the use of NoSQL. However, if most of data does not require denormalisation, which cannot be avoided, think about a relational base with JsonField to store some data.
\r\n\r\nDo not use null=True or blank=True for BooleanField. It should also be pointed out that it is better to specify default values for such fields. If you realise that the field can remain empty, you need NullBooleanField.
\r\n\r\nThe best place to allocate business logic for your project is in models, namely method models and model manager. It is possible that method models can only provoke some methods/functions. If it is inconvenient or impossible to allocate logic in models, you need to replace its forms or serializers in tasks.
\r\n\r\nDo not duplicate model fields in ModelForm or ModelSerializer without need. If you want to specify that the form uses all model fields, use MetaFields. If you need to redefine a widget for a field with nothing else to be changed in this field, make use of Meta widgets to indicate widgets.
\r\n\r\nUsing ModelName.DoesNotExist instead of ObjectDoesNotExist makes your exception intercepting more specialised, which is a positive practice.
\r\n\r\nWhile using choices, it is recommended to:
\r\n\r\nkeep strings instead of numbers in the database (although this is not the best option from the point of optional database use, it is more convenient in practise as strings are more demonstrable, which allows the use of clear filters with get options from the box in REST frameworks).
\r\nvariables for variants storage are constants. That is why they must be indicated in uppercase.
\r\nindicate the variants before the fields lists.
\r\nif it is a list of the statuses, indicate it in chronological order (e.g. new, in_progress, completed).
\r\nyou can use Choices from the model_utils library. Take model Article, for instance:
\r\nfrom model_utils import Choices
class Article(models.Model):
\r\n\r\nSTATUSES = Choices(
\r\n\r\n(0, 'draft', _('draft')),
\r\n(1, 'published', _('published')) )
status = models.IntegerField(choices=STATUSES, default=STATUSES.draft)
\r\n…
\r\n\r\n
Using ORM, do not add an extra method call all before filter(), count(), etc.
\r\n\r\nIf it is justified, replace several BooleanFields with one field, status-like. e.g.
\r\n\r\nclass Article(models.Model):
\r\n\r\nis_published = models.BooleanField(default=False)
\r\nis_verified = models.BooleanField(default=False)
\r\n…
Assume the logic of our application presupposes that the article is not published and checked initially, then it is checked and marked is_verified in True and then it is published. You can notice that article cannot be published without being checked. So there are 3 conditions in total, but with 2 boolean fields we do not have 4 possible variants, and you should make sure there are no articles with wrong boolean fields conditions combinations. That is why using one status field instead of two boolean fields is a better option:
\r\n\r\n\r\n\r\n
class Article(models.Model):
\r\n\r\nSTATUSES = Choices('new', 'verified', 'published')
\r\n\r\n\r\n\r\n
\r\n\r\n
status = models.IntegerField(choices=STATUSES, default=STATUSES.draft)
\r\n…
This example may not be very illustrative, but imagine that you have 3 or more such boolean fields in your model, and validation control for these field value combinations can be really tiresome.
\r\n\r\n\r\n\r\n
Do not add model names to fields if there is no need to do so, e.g. if table User has a field user_status - you should rename the field into status, as long as there are no other statuses in this model.
\r\n\r\nAlways use PositiveIntegerField instead of IntegerField if it is not senseless, because “bad” data must not go to the base. For the same reason you should always use unique,unique_together for logically unique data and never use required=False in every field.
\r\n\r\nYou can use ModelName.objects.earliest('created'/'earliest') instead of order_by('created')[0] and you can also put get_latest_by in Meta model. You should keep in mind that latest/earliest as well as get can cause an exception DoesNotExist. Therefore, order_by('created').first() is the most useful variant.
\r\n\r\nDo not use len to get queryset’s objects amount. The count method can be used for this purpose. Like this: len(ModelName.objects.all()), firstly the query for selecting all data from the table will be carried out, then this data will be transformed into a Python object, and the length of this object will be found with the help of len. It is highly recommended not to use this method as count will address to a corresponding SQL function COUNT(). With count, an easier query will be carried out in that database and fewer resources will be required for python code performance.
\r\n\r\nDo not use queryset as a boolean value: instead of if queryset: do something use if queryset.exists(): do something. Remember, that querysets are lazy, and if you use queryset as a boolean value, an inappropriate query to a database will be carried out.
\r\n\r\nUsing model help_text in fields as a part of documentation will definitely facilitate the understanding of the data structure by you, your colleagues, and admin users.
\r\n\r\nDo not use FloatField to store information about the quantity of money. Instead, use DecimalField for this purpose. You can also keep this information in cents, units, etc.
\r\n\r\nnull=True - Allows column to keep null value.
\r\n\r\nblank=True - Will be used only if Forms for validation and not related to the database.
\r\n\r\nIn text-based fields, it's better to keep default value.
\r\n\r\nblank=True
\r\n\r\ndefault=''
\r\n\r\nThis way you'll get only one possible value for columns without data.
\r\n\r\nDo not add _id suffix to ForeignKeyField and OneToOneField.
\r\n\r\nIn all non abstract models, add methods unicode(python 2) or str(python 3). These methods must always return strings.
\r\n\r\nDo not use Meta.exclude for a model’s fields list description in ModelForm. It is better to use Meta.fields for this as it makes the fields list transparent. Do not use Meta.fields=”all” for the same reason.
\r\n\r\nSometimes even a separate folder for each FileField will not be enough if a large amount of downloaded files is expected. Storing many files in one folder means the file system will search for the needed file more slowly. To avoid such problems, you can do the following:
\r\n\r\ndef get_upload_path(instance, filename):
\r\n\r\nreturn os.path.join('account/avatars/', now().date().strftime("%Y/%m/%d"), filename)
\r\n\r\n\r\n\r\n
class User(AbstractUser):
\r\n\r\navatar = models.ImageField(blank=True, upload_to=get_upload_path)
\r\n\r\n\r\n\r\n
If you want to share some logic between models, you can use abstract models.
\r\n\r\nclass CreatedatModel(models.Model):
\r\n\r\ncreated_at = models.DateTimeField(
\r\n\r\nverbose_name=u"Created at",
\r\n\r\nauto_now_add=True
\r\n\r\n)
\r\n\r\nclass Meta:
\r\n\r\nabstract = True
\r\n\r\nclass Post(CreatedatModel):
\r\n\r\n...
\r\n\r\nclass Comment(CreatedatModel):
\r\n\r\n...
\r\n\r\nThe bigger project you work on, the more you repeat the same code in different places.
\r\n\r\nTo keep your code DRY and allocate business logic in models, you can use custom Managers and Queryset.
\r\n\r\nFor example. If you need to get comments count for posts, from the example above.
\r\n\r\nclass CustomManager(models.Manager):
\r\n\r\ndef with_comments_counter(self):
\r\n\r\nreturn self.get_queryset().annotate(comments_count=Count('comment_set'))
\r\n\r\nNow you can use:
\r\n\r\n\r\n\r\n
posts = Post.objects.with_comments_counter()
\r\n\r\nposts[0].comments_count
\r\n\r\nIf you want to use this method in chain with others queryset methods,
\r\n\r\nyou should use custom QuerySet:
\r\n\r\nclass CustomQuerySet(models.query.QuerySet):
\r\n\r\n"""Substitution the QuerySet, and adding additional methods to QuerySet
\r\n\r\n"""
\r\n\r\ndef with_comments_counter(self):
\r\n\r\n"""
\r\n\r\nAdds comments counter to queryset
\r\n\r\n"""
\r\n\r\nreturn self.annotate(comments_count=Count('comment_set'))
\r\n\r\nNow you can use:
\r\n\r\nposts = Post.objects.filter(...).with_comments_counter()
\r\n\r\nposts[0].comments_count

UEFI systems :
\r\n\r\n- EFI system met partition type = 'EF00' partion vlaggen = 'boot,esp'
\r\n\r\n- EFI op windows :
\r\n\r\npartitie type = '0700' FAT32 partitie vlaggen = 'msftdata'
\r\n\r\nSome newer systems use the GUID Partition Table (GPT) format. This was specified as part of the Extensible Firmware Interface (EFI), but it can also be used on BIOS platforms if system software supports it; for example, GRUB and GNU/Linux can be used in this configuration. With this format, it is possible to reserve a whole partition for GRUB, called the BIOS Boot Partition. GRUB can then be embedded into that partition without the risk of being overwritten by other software and without being contained in a filesystem which might move its blocks around.
\r\n\r\nWhen creating a BIOS Boot Partition on a GPT system, you should make sure that it is at least 31 KiB in size. (GPT-formatted disks are not usually particularly small, so we recommend that you make it larger than the bare minimum, such as 1 MiB, to allow plenty of room for growth.) You must also make sure that it has the proper partition type. Using GNU Parted, you can set this using a command such as the following:
\r\n\r\n\r\n# parted /dev/disk set partition-number bios_grub on NIET gebruiken op UEFI systemen !\r\n\r\n\r\nIf you are using gdisk, set the partition type to ‘0xEF02’. With partitioning programs that require setting the GUID directly, it should be ‘21686148-6449-6e6f-744e656564454649’.
\r\n\r\nCaution: Be very careful which partition you select! When GRUB finds a BIOS Boot Partition during installation, it will automatically overwrite part of it. Make sure that the partition does not contain any other data.
\r\n\r\nNote:
\r\n\r\nGparted /dev/disk hangs wanneer GPT disk zonder een bios_grub partitie in legacy mode
\r\n\r\nals grub-install correct uitgevoerd is zal de grub2 core.img plaatsen op de EF02 partitie

\r\n\r\nBoot an recent Debian live system on USB or DVD.
\r\n\r\nBackup your data!
\r\n\r\nMy lecagy boot system had a 243MiB ext2 partition mounted on /boot. This partition is never encrypted. It is where the grub files and Linux kernels reside. Check by double clicking on the partition icon on the live-disk-desktop and have a look inside.

\r\nAs you can see in the following partition table of the Debian legacy boot system my /boot partition is number 1 (/dev/sdb1).
Although 1 is the default value for standard debian installations better check!
\r\nThe live system has identified this partition as /dev/sdb. The debian system on your harddisk could reference it differently.

\r\nShrink the /root partition to 200MB in order to free 43MB (see partition 1 below).
Create a new 43MB partition for efi using gparted with partition code EF00 (EFI system) and flag it bootable. Format the partition with a fat32 [1] filesystem (see partition 2 below).

The next step differs whether the root-filesystem is encrypted or not.
\r\n\r\nMount the / (root) filesystem.
\r\n\r\nFor non-encrypted root filesystems a simple mount will do.
\r\n\r\n\r\n\r\n\r\n# mount -t ext4 /dev/sdb5 /mnt
\r\n
For encrypted root filesystems the mounting procedure can be a little tricky especially when the root filesystem resides inside a logical volume which is encrypted. This section shows how to mount and unmount an encrypted root-filesystem.
\r\n\r\n The recovery mode of the Debian 9 Stretch installer disk automates all following steps. Try this first. If it does not work follow the rest of this section.

Update the entries in /mnt/etc/fstab to reflect the partition changes above. Compare the UUID’s there with the ones listed here:
\r\n\r\n\r\n\r\n\r\n# ls /dev/disk/by-uuid
\r\n
\r\n
Add the new UEFI partition (see last line in /etc/fstab below) in order to get it mounted permanently on /boot/efi.

The Linux efibootmgr command line utility is very handy when it comes to managing UEFI boot menu. It’s assumed that you have installed Linux in UEFI mode.
\r\n\r\nYou can install the efibootmgr command line utility with the following commands.
\r\n\r\nDebian/Ubuntu/Linux Mint
\r\n\r\n\r\n\r\nsudo apt install efibootmgr\r\n\r\n\r\nFedora, CentOS, RedHat
\r\n\r\n\r\n\r\nsudo dnf install efibootmgr\r\n\r\n\r\nSuSE
\r\n\r\n\r\n\r\nsudo zypper install efibootmgr\r\n\r\n\r\nArch Linux/Manjaro
\r\n\r\n\r\n\r\nsudo pacman -S efibootmgr\r\n\r\n\r\nSimply run the following command. In some Linux distributions like Debian, you need to run it with sudo privilege.
\r\n\r\nefibootmgr\r\n\r\n\r\nThis command allows you to view the default boot entry (BootCurrent), boot order and all boot entries. Each boot entry is identified by a boot number in hexadecimal. The asterisk (*) means the boot entry is active.+
\r\n\r\nYou can also add -v option to show verbose information.
\r\n\r\nefibootmgr -v\r\n\r\n\r\nYou can see the EFI system partition number, the partition table type (GPT), UUID of the EFI system partition and the boot loader file.
\r\n\r\nFirst, copy the current boot order. For example, my boot order is:
\r\n\r\n\r\n0013,0012,0014,0000,0001,0002,0003,000D,0011,0007,0008,0009,000A,000B,000C,000E\r\n\r\nThen type in the following command
\r\n\r\n\r\n\r\nsudo efibootmgr -o\r\n\r\n\r\nAnd append the boot order to the above command.
\r\n\r\n\r\n\r\nsudo efibootmgr -o 0013,0012,0014,0000,0001,0002,0003,000D,0011,0007,0008,0009,000A,000B,000C,000E\r\n\r\n\r\nLet’s say you want 0012 to be the first boot entry. All you have to do is move it to the left of 0013 and press Enter.
\r\n\r\nsudo efibootmgr -o 0012,0013,0014,0000,0001,0002,0003,000D,0011,0007,0008,0009,000A,000B,000C,000E\r\n\r\n\r\nIf you have installed multiple Linux distributions on your computer, but one of the Linux distribution doesn’t have a UEFI boot entry, you can manually add it.
\r\n\r\nBoot into the Linux distro that doesn’t have UFEI boot entry. Then make sure it has the EFI version of GRUB boot loader installed.
\r\n\r\nDebian/Ubuntu/Linux Mint
\r\n\r\n\r\n\r\nsudo apt install grub-efi\r\n\r\n\r\nFedora
\r\n\r\n\r\n\r\nsudo dnf install grub2-efi-modules\r\n\r\n\r\nThen mount the EFI system partition (ESP) under /boot/efi/ directory. In this example, /dev/sda7 is the ESP.
\r\n\r\nsudo mount /dev/sda7 /boot/efi/\r\n\r\n\r\nThen install Grub boot loader to ESP.
\r\n\r\n\r\n\r\nsudo grub-install /dev/sda --target=x86_64-efi --efi-directory=/boot/efi/\r\n\r\n\r\nx86_64-efi means that we are going to install Grub for UEFI firmware. The default target is i386-pc, which is for traditional BIOS firmware.
Now, you should see a new entry in UEFI boot menu with the bootmgr command. Under the hood, the Grub installer first installs a .efi booloader file to /boot/efi/EFI/<label>/ directory. Usually it’s named grubx64.efi. Then it runs the following command to add a new entry in UEFI boot menu.
\r\n\r\nefibootmgr -c -d /dev/sda -p 7 -L <label> -l /EFI/<label>/grubx64.efi\r\n\r\n\r\nNewly added entry will be the first in boot order.
\r\n\r\nnew entry for debian
\r\n\r\n\r\n\r\nefibootmgr --create --disk=/dev/sda --part=1 --label="debian" --loader='EFI/debian/shimx64.efi'\r\n\r\n\r\nLet’s say you have installed multiple Linux distributions on a hard disk so you have multiple boot entries just like the above screenshot. And now you deleted a Linux distro but the boot entry is still there. To remove the respective boot entry, run:
\r\n\r\n\r\n\r\nsudo efibootmgr -b <bootnum> -B\r\n\r\n\r\nFor example,
\r\n\r\n\r\n\r\nsudo efibootmgr -b 0014 -B\r\n\r\n\r\n-b option specify the boot number. -B option delete that boot number.
A boot entry followed by asterisk indicates that it’s active. Otherwise it’s inactive. To set a boot entry active, run:
\r\n\r\n\r\n\r\nsudo efibootmgr -b <bootnum> -a\r\n\r\n\r\nTo set a boot entry inactive, run:
\r\n\r\n\r\n\r\nsudo efibootmgr -b <bootnum> -A\r\n\r\n\r\n", "db_count": 136 }, { "taaknaam": "herzet-interface-eth0-netwerk", "taaktext": "
