Is there A Way To Format Serialized Response for Groups and their Permissions in Django Rest Framework?
I created an API endpoint in which I am sending a JSON data. to create a group and then assigned permission to the models (e.g add_user, change_user etc) programmatically. It works fine. The issue now is that I will like to format data retrieved in the same format I sent it in This is for the Django's inbuilt Group, Permissions, ContentType View.py class RolePermissionListCreateAPIView(generics.ListCreateAPIView): queryset = Group.objects.all() serializer_class = RolePermissionSerializer permission_classes = (IsAuthenticated,) def list(self, request): if not request.user.has_perm("auth.view_group"): return Response({"error":"Permission denied."}, status=status.HTTP_401_UNAUTHORIZED) queryset = self.get_queryset() serializer = RolePermissionSerializer(queryset, many=True) return Response(serializer.data) Serializer.py class PermissionSerializer(serializers.ModelSerializer): codename = serializers.CharField(allow_blank=False) class Meta: model = Permission fields ="__all__" class RolePermissionSerializer(serializers.ModelSerializer): name = CharField(max_length=100) permissions = PermissionSerializer(many=True) class Meta: model = Group fields = ["id", "name", "permissions"] Data [ { "id": 1, "name": "Administrator", "permissions": [ { "codename": "add_user" }, { "codename": "change_user" }, { "codename": "deactivate_user" }, { "codename": "delete_user" }, { "codename": "export_user" }, { "codename": "import_user" }, { "codename": "print_user" }, { "codename": "view_user" } ] } ] This actually the way I want the data to be formatted: { "role_name": "Administrator", "modules": [ { "module_name": "User", "can_view": "True", "can_add": "True", "can_edit": "True", "can_delete": "True", "can_print": "True", "can_deactivate": "True", "can_import": "True", … -

Custom Admin Page with Fields as Objects
I have 3 models: Category, SubCategory, Product. Category and SubCategory have one-to-many relationship. SubCategory and Product have many-to-many relationship(ManyToManyField is in Product). Currently, admin page for Product shows one field for SubCategory as multiple choice field. But I want fields for Product to be as Category objects. SubCategories should be divided by their Categories and user should be able to choose a SubCategory from each of this field. Can't work it out.

Django - Redirecting to a view with <select> <option>
I'm taking my first steps on django, and i'm stuck with this problem: I'm planning to use a selection box to choose a chapter of the book/novel and be redirected to it. Either using a "go" button or just redirecting instantly. Preferably the latter. But i don't really know how to make it work. Thanks in advance. url.py urlpatterns = [ path('<int:id>/<int:pk>', views.ChapterView.as_view(), name='chapter_view'), ] views.py class ChapterView(DetailView): model = Chapter context_object_name = 'chapter' template_name = 'chapter.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['chapter_group'] = Chapter.similar_chapter(self.get_object()) context['novel'] = Novel.objects.get(novel_title=self.get_object().chapter_novel) return context HTML <select class="form-select" aria-label="Default select example"> <option selected>{{ chapter.chapter_number }} - {{ chapter.chapter_title }}</option> {% for capitulos in chapter_group %} <option value="{% url 'chapter_view' novel.id capitulos.pk %}"> {{ capitulos.chapter_number }} - {{ capitulos.chapter_title }} </option> {% endfor %} </select> I tried using an <a href={% url 'chapter_view' novel.id capitulos.pk %}> inside the option, to no avail. Now i'm searching ways to do it, but haven't found nothing using .as_view() like i'm using. -

Django ORM querying data in JSONField

Howto properly test a django library
I frequently run into practical problems when I want to test a library I develop that is a django app. Django apps can be developed independently, like DRF etc. For testing, you either need a django project, or at least a settings.py file or the like, see here. But I don't get it how to do that properly for a "standalone" library. I need to generate migrations for that library (if it contains models) - so I need a manage.py file to invoke manage.py makemigrations, I need to check if the lib is integrating in project properly (in my case apps are full-fledged plugins, I am using GDAPS). What is the best approach here? should I create a separate "test project" in a separate repo that uses my library and tests it? should I create a project within my library's tests directory and use that? CAVE python paths... should I not use the project at all and mimick everything - how? Please give me at least a hint in some direction. -
How to best use pyproject.toml files in Django project/app hierarchies?
I'm in the process of modernizing the conventions around Django applications at our company, but I've got a lot of catching up to do. One of the main question marks right now is pyproject.toml, which would be convenient (though not mandatory) for configuring the Black code formatter, as well as listing dependencies for pip-compile. Until now, we've used this monorepo structure for our client projects: . |_ .git |_ apps | |_ app_1 # created with 'django-admin startapp' | |_ app_2 # likewise | |_ setup.py | |_ project # created with 'django-admin startproject cool_site', then renamed | |_ manage.py | |_ cool_site | |_ __init__.py | |_ settings.py | |_ ...other files created by 'startproject'... | |_ support # various helper scripts etc., not a Python package In development, we've used Vagrants or docker-compose and bind mounted this repo into the VM or container for convenient development on the host machine, and run pip install -e apps to have the packages inside apps be importable by the manage.py runserver process. (On our production servers, we either deploy this contanerized, or just git pull this repo in place with Ansible, then install without -e, and use gunicorn instead of runserver) … -

Django: How to create an tabular inline like the one in admin panel with "+ Add another"?
I currently rely on the admin panel to create or edit a new/existing order (i.e. Order with its children model OrderItem in the tabular inline). But this time I need to create a view with the same function for non-admin users. More specifically, I need the + Add another button in the tabular inline for users to add more Order Items themselves when necessary. I have looked into a few stackoverflows (one of them) and books. So far they at most only mentioned about inlineformset_factory, but not how to create the + Add another. Any ideas please? Thank you! -
How can I create an book index with Python?

But, on this section page, I only have the last three chapters, so, when I click, I can move forward to the single page where I am. This is my HTML template. <ul> {% for chapter in book %} <li> <a href="#{{ chapter }}">{{ chapter }}</a> </li> {% endfor %} </ul> But, how can I access a section in example/book?page=2#chapter_five? I tried to create a function to find the chapter in a for loop with all the pages, but I got that the object was not iterable.

Is django's SCRIPT_NAME applied to STATIC_URL?

Django 'DetailView' object has no attribute '_meta'
This has floored me. I'm building a model with Django & REST API, and I'm having trouble rendering the DetailView for individual cars to the browser. The ListView works fine, but I'll include the code too since they are interlinked. In particular, I can't get the get_object() function to work properly. The first approach I tried used this approach: views.py class CarDetailView(generics.RetrieveUpdateDestroyAPIView): renderer_classes = [TemplateHTMLRenderer] template_name = 'car-detail.html' queryset = Car.objects.all() lookup_field = Car.id @action(detail=True, renderer_classes=[TemplateHTMLRenderer]) def get(self, request, *args, **kwargs): car = self.get_object() return Response({ 'car': car, }) While the page rendered properly with no errors, none of the template tags worked. Only {{ car.model }}, which returned None.
