How can I solve the problems of Testing that are not in the same model?
In my model, there are fields as follows. class Home(TitleSlugDescriptionModel): seller= models.ForeignKey("data.seller", null=True, on_delete=models.SET_NULL) date = models.DateField() picture = models.ImageField(upload_to="images") In my test.py class HomeTestCase(TestCase): def test_random(self): with open("img/no-image.jpg", "rb") as f: for home in range(10): G(Home, picture=ImageFile(f), seller=F(name="test1"), I have a problem when I test. It alerts that: django_dynamic_fixture.ddf.InvalidConfigurationError: ('homes.models.Home.seller', BadDataError('data.models.Seller', ValidationError({'data': ['This field cannot be blank.']}))) I know that This field cannot be blank, And I solved the problem as follows. [add name data] class HomeTestCase(TestCase): def test_random(self): with open("img/no-image.jpg", "rb") as f: for home in range(10): G(Home, picture=ImageFile(f), seller=F(name="test1"), data=F(name="test2") It does not work and alerts that django_dynamic_fixture.ddf.InvalidConfigurationError: Field "data" does not exist. I don't know how to fix it. Can someone recommend me? Thank you very much -

CSS definitions in django-allauth account templates
I am trying out django-allauth and have come across a block while customizing the allauth account templates. I am presently working on the emails.html template but I am unable to find any definition for the css classes used inside the default templates. CSS classed such as ctrlHolder or primary_email.

Django Guardian - Check Permission during filtering
Im using Django Guardian to use Instance Permissions. It works well but I have a question about filtering. Lets say we have a models called FakeItem. Lets say we want to filter FakeItems list with only item with a specific permission. @staticmethod def purge_list(entity_list , userOrUsername, permission_name): requesting_user = userOrUsername if not isinstance(userOrUsername, User): requesting_user = User.objects.get(username = username) acl_listed = [] total_rows = 0 for entity in entity_list: if requesting_user.has_perm(entity, permission_name): acl_listed.append(entity) total_rows = total_rows + 1 return { "list" : acl_listed , "totals" : total_rows } This is an example of a method to purge list from item the user can access. Unfortunally this method is called AFTER I get the total list from database with a previous filter. I need to make a O(n) interation over the list to purge it. I need something to purge the list directly in the original filter to optimize the query. search_filter = Q() search_filter = search_filter & Q(name__icontains = "foo") search_filter = search_filter & Q(some_guardian_filter) already_purged_list = FakeItem.objects.filter(search_filter) Guardian's Documentation only explain how to use single method like has_perm etc... -

VS Python attach remote. Starts running for a couple seconds then stops
So I have this Django app inside of Docker running and I'm trying to attach VS code to it so I can debug here is my launch file { // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "Python: Remote Attach", "type": "python", "request": "attach", "port": 8800, "host": "192.168.99.100", "pathMappings": [ { "localRoot": "${workspaceFolder}", "remoteRoot": "." } ] } ] } The host 192.168.99.100 is the IP that Docker runs on(I'm using Docker Toolbox). For some reason it runs for like 5 seconds then cancels itself. Any suggestions? -

Django queryset using select_related and prefetch_related
models.py class Question(Model): pass class Topic(Model): question = models.Foreignkey(Question) class Syllabus(Model): topic = models.Foreignkey(Topic) #The Bridge Model class Test_Syllabus(Model): test = models.Foreignkey(Test) syllabus = models.Foreignkey(Syllabus) class Test (Model): pass I have a test object as follows: test = Test.objects.get(id=pk) Using the test object, I want to get the related queryset of questions. So, I tried the following code: questions = test.test_syllabus_set.all() #don't know how to go further from here I think it has something to do with select_related and prefetch_related. Please help me out with a perfect query for this use case. -
