Set graphene field when returning from query resolver
We are currently upgrading from an old version of graphene (0.99) to a new one (2.15). In the old version, we were able to set the value of a field in the query resolver. For example: class DogType(DjangoObjectType): selected = graphene.Boolean() class Meta: model = Dog class DogsQuery(graphene.ObjectType): dogs = graphene.List(DogType) resolve_dogs(self, info): top_dogs = Dogs.objects.all()[:10] return [DogType(d, selected=(i == 0)) for i, d in enumerate(top_dogs)] This resolver hands back a list of DogTypes, and the first dog in the list has "selected=True" while the others have "selected=False". It resolves successfully. In newer versions of graphene, this throws an error: "'DogType' object has no attribute 'pk'". I presume this is because newer versions of graphene don't want us to return Types. So I'm just wondering if it is possible to set the graphene field "selected" in the query resolver itself in newer versions of graphene? -

Django+Postgres Broken transaction after checking for uniqueness
I created a simple project with one application and a model. https://github.com/SergeyMalash/test_unique It has two unique fields. Also in the settings I specified ATOMIC_REQUESTS When I make a POST request with an invalid IP address, an error occurs (screenshot) My assumptions: As far as I understand, during the check for uniqueness, a DataError exception occurs, since postgres can't compare inet field with an incorrect IP address This breaks all subsequent calls to the database. https://github.com/encode/django-rest-framework/blob/master/rest_framework/validators.py#L71 Am I right? How can this be fixed? I need to leave ATOMIC_REQUESTS enabled My issue is partially related to https://github.com/encode/django-rest-framework/issues/3381 But I didn't find a solution there. `https://pastebin.com/bDuQvje4` `https://pastebin.com/7VaWjMaZ` -
Django/Wagtail Rest Framework API Ordering/Pagination
I am using wagtail. I have serialized my API. I want to order them by -first_published_at, when someone hit my API url api/v2/pages they will see an ordered API without filtering it via URL. here is my api.py code: class ProdPagesAPIViewSet(BaseAPIViewSet): renderer_classes = [JSONRenderer] filter_backends = [FieldsFilter, ChildOfFilter, AncestorOfFilter, DescendantOfFilter, OrderingFilter, TranslationOfFilter, LocaleFilter, SearchFilter,] meta_fields = ["type","seo_title","search_description","first_published_at"] body_fields = ["id","type","seo_title","search_description","first_published_at","title"] listing_default_fields = ["type","seo_title","search_description","first_published_at","id","title","alternative_title","news_slug","blog_image","video_thumbnail","categories","blog_authors","excerpt","content","content2","tags",] nested_default_fields = [] ordered_queryset= [] name = "pages" model = AddStory api_router.register_endpoint("pages", ProdPagesAPIViewSet) I have tried ordered_queryset= [AddStory.objects.order_by('-first_published_at')] But it's not ordered by the newest published stories. How should I do the query? Here is my API response { "meta": { "total_count": 6 }, "items": [ { "id": 4, "meta": { "type": "blog.AddStory", "seo_title": "", "search_description": "", "first_published_at": "2022-08-30T11:05:11.341355Z" }, { "id": 6, "meta": { "type": "blog.AddStory", "seo_title": "", "search_description": "", "first_published_at": "2022-08-30T11:13:47.114889Z" }, { "id": 7, "meta": { "type": "blog.AddStory", "seo_title": "", "search_description": "", "first_published_at": "2022-08-31T11:13:47.114889Z" }, -
How to extend template from library
I have a Django app, where I have customized the admin base_site.html. I have installed a library (Django admin tools) which also extends the admin base_site.html Obviously, my custom base_site.html does not load anymore. I'd like to extend the base_site from django-admin-tools but I did not find how. I have read the Django docs (Template inheritence and extends) but could not find anything with more details. I have also seen the {% extend "project:path/file.html" %} notation but could not find documentation about how the part before the : works. I have tried : {% extend "admin_tools/base_site.html" %} {% extend "admin_tools/admin/base_site.html" %} {% extend "admin/admin_tools/base_site.html" %} {% extend "admin/admin_tools/menu/templates/admin/base_site.html" %} {% extend "admin_tools/menu/templates/admin/base_site.html" %} {% extend "admin_tools:menu/templates/admin/base_site.html" %} How can I extend this file ? And, if it exists, where can I find the documentation on how exactly extend works ? My template config looks like this : TEMPLATES = [ { "BACKEND": "django.template.backends.django.DjangoTemplates", "DIRS": [BASE_DIR / "templates"], "APP_DIRS": False, "OPTIONS": { "context_processors": [ "django.template.context_processors.debug", "django.template.context_processors.request", "django.contrib.auth.context_processors.auth", "django.contrib.messages.context_processors.messages", # Custom context processors "utils.context_processors.settings", "social_django.context_processors.backends", "social_django.context_processors.login_redirect", ], 'loaders': [ "admin_tools.template_loaders.Loader", "django.template.loaders.app_directories.Loader", # insert your TEMPLATE_LOADERS here ] }, }, ] -

That is makemigrations is done. But not migrate. fipi_task_descriptions.TaskDescription: (models.E012) 'constraints' refers to the nonexistent field 'exam_section__exam_part'. Could you tell me whether it is possible to organise unique together of exam_part and name and exam_part and priority respectively? -

I've been trying to use Tags in my project, using the django application django-taggit. I already put them in the models and it works fine so far.

Why does Django Money show 3 decimals with decimal_places=2?
I'm very confused by this: >>> from djmoney.models.fields import Money >>> Money("0.129", "EUR", decimal_places=2) Money('0.129', 'EUR') I've expected to see Money('0.12', 'EUR') or Money('0.13', 'EUR'). I know I can use round(2) to get the expected result, but what influence does decimal_places have? If it stores the data anyway, why/when should I use the parameter? The docs are not helpful. -
