Linking cart model to stripe checkout
How can I link price and items from cart Model to the Stripe checkout in Django Web Framework? I get and ValueError at /create_checkout_session when I changed default settings to the code below.

Is editable=False required?
I am developing a model, the only actions that can be performed on an instance of it are view and delete. Moreover, all these actions must take place in the StackedInline, which is bound to the ModelAdmin class of another model. Model example: class IncludingModel(models.Model): ... class ReadAndDeleteOnlyModel(models.Model): field1 = models.TextField(verbose_name="First field", editable=False) field2 = models.TextField(verbose_name="Second field", editable=False) including_model_instance = models.ForeignKey(IncludingModel, related_name="read_and_delete_only_instances") Admin example class ReadAndDeleteOnlyModelInline(admin.StackedInline): model = ReadAndDeleteOnlyModel readonly_fields = ("field1", "field2") def has_add_permission(self, request, obj): return False @admin.register(IncludingModel) class IncludingModelAdmin(admin.ModelAdmin) inlines = (ReadAndDeleteOnlyModelInline,) Interaction with ReadAndDeleteOnlyModel instances occurs only in IncludingModelAdmin. After removing editable = False, my fields are still read-only due to the fact that I specified them in readonly_fields. This begs the question, is editable = False needed in my case? -

Override Wagtail delete confirmation message
I would like to override the delete message (to make it more informative, like “if you delete, you will lose 5 items belong to your account”). My idea is whenever someone deletes my “Member”, it will also delete all the items belong to that member, and the confirmation message should provide more information. I find that the confirmation message comes from a function named “confirmation_message” in wagtail.contrib.modeladmin.views, at DeleteView class. This function will provide the message for Wagtail delete's template. This is my Member class: class Member(ClusterableModel): user = models.OneToOneField(User, on_delete=models.CASCADE) email_confirmed = models.BooleanField(default=False) phone = PhoneNumberField(blank=True) phone_2 = PhoneNumberField(blank=True) inside_scoop = models.TextField(blank=True) lifetime_member = models.BooleanField(default=False) activation_date = models.DateField(null=True, blank=True, default=timezone.now) deactivation_date = models.DateField(null=True, blank=True) points_balance = models.IntegerField(default=0) favorite_properties = models.ManyToManyField( PropertyPage, blank=True, related_name="favorite_properties" ) base_form_class = MemberFormAdmin def delete(self: object, *args: list, **kwargs: dict) -> None: PropertyPage.objects.filter(owner=self.user).delete() self.user.delete() return super(self.__class__, self).delete(*args, **kwargs) This is the default confirmation message that comes from Wagtail: this lies in wagtail -> contrib -> modeladmin -> views.py And this is the delete template: this lies in wagtail -> contrib -> modeladmin -> templates → modeladmin → delete.html This is the message for staff in admin portal: Please help me with this case, thank you. -

AttributeError: 'QuerySet' object has no attribute 'tags' when trying to save quotes and tags with ClusterableModel and ClusterTaggableManager
I am trying to save some quotes from a csv file to my django model using python manage.py shell because I could not use django-import-export to do it. I asked about it at Tags imported but relationship not imported with django-import-export but nobody answered and I could not find more things to try after googling. After reading the documentation and previous answers here about django querysets and tagging, I managed to save most of each quote but the tags are not saved. The query set does not return tags field, which causes the AttributeError. Please see shell output q: <QuerySet... below My tag model follows https://docs.wagtail.io/en/stable/reference/pages/model_recipes.html#custom-tag-models. From django-admin, the relationships are working. So the missing piece of the puzzle is saving the tags.

How to add DjangoFilterBackend in APIView of Django rest framework?
I am trying to add all CRUD operations into a single endpoint using APIVIEW in DRF, as I have heard, thats what senior developers do (all apis into a single endpoint). But in get request, I have to use a Filterbackends, pagination and also some custom filter logic.
