Django display error messages for default login backend
I am using Django's default authentication backend, and I cannot get the messages framework to work with it to show error messages (such as incorrect username, invalid password etc). Everything that I have searched through here to suggest to make a custom authentication backend, but is there any easier way to do it? I already have a form which is subclassing the AuthenticationForm to use form_valid method, is there anything I could do there? Any help would be really appreciated. -

mock.patch() Not patching function in module call, but is in test function
So I am trying to mock a function and it is not being mocked in the module where it is being called, but it when called directly in the test function. I am unsure what I'm doing wrong. I use patch all the time without any problems. So in the test I have below from unittest.mock import patch from django.test import TestCase from web.utils.registration import test_render_mock class TestRenderMock(TestCase): @patch("django.shortcuts.render") def test_render_mock(self, render_mock): request = self.make_request() # Calls render in same way in function below test_render_mock(request) from django.shortcuts import render r = render(request, 'c') print(type(r)) which is calling the function in the file web/utils/registration.py from django.shortcuts import render def test_render_mock(request): r = render(request, 'registration/signup_link_error.html') print(type(r)) And it isn't mocking the render call in the function test_render_mock but it is in the test function test_render_mock(). The console output is below. <class 'django.http.response.HttpResponse'> <class 'unittest.mock.MagicMock'> I have no idea what I'm doing wrong. Any help would be appreciated.

Test a Django model that uses request.user in save_model
I have a Django model that overrides save_model in order to automatically save the current authenticated user into a field on save. The question is, how in a unit test can I test the creation of this model, without having to go through a view? The model: class SomeClass(models.Model): def save_model(self, request, obj, form, change): self.prevent_update() if not obj.pk: # Only set added_by during the first save. obj.created = request.user super().save_model(request, obj, form, change) The test just wants to set up SomeClass before doing some other stuff. class SomeClassTestCase(TestCase): def setUp(self): self.assertTrue(request.user) SomeClass.objects.create(name="abc") I know that there is a request getting set up automatically, since request.user doesn't fail with request being None; instead, the query constraint fails because the user is null. How do I set a user on the request that appears to have been passed into save_model Alternatively, I know I can setup a request using RequestFactory and generate a user. In that case, how do I get that into the test so that the SomeClass.objects.create actually sees it. -
Python/Django creating several classes from variable through looping
I'm working with Python Django and I'm trying to create a forum with several subpages - each subpage concerns another topic and should look the same but store different posts. I want to create several classes (not instances!) with a similar name and same attributes. Each class should have another template name and render other posts. Something like this: my_variable = 'part_of_class_name' for class_number in range(2, 5): class_name = my_variable + str(class_number) + '(SameParentClass)' class class_name: template_name = 'template' + str(class_number) + '.html' Of course, the code above doesn't work, is it a possibility to pass a variable to a class name? I want the following: part_of_class_name2(SameParentClass), part_of_class_name3(SameParentClass), part_of_class_name4(SameParentClass). How can I do it by looping? I want to avoid making three classes. -
Show model parent fields in Django's admin model details
I let most of my models inherit from: class TimeStampedModel(models.Model): created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Meta: abstract = True get_latest_by = 'updated_at' Like this: class Sale(TimeStampedModel): ip_address = models.GenericIPAddressField(null=True) # ... However, if I visit /admin/myapp/sale/123/change/ I only see the ip_address field. How can I also get to see the created_at and updated_at fields? Possibly, without having to specify every single field of Sale in a list. -

Django failed with Authentication credentials were not provided

Directing Output Paths of Altered Files
I am sorry if this is a dumb question, it seems like it would be simple but has been driving me nuts for days. How can I direct the destination of the output file "pdf01.pdf" to my db? PdfFileWriter().write(open("pdf01.pdf", "wb")) I have gotten the file to successfully output however, it output's to my src directory. My models.py is structured like so: class Model(models.Model): char = models.CharField(max_length=50, null=False, blank=False) file = models.FileField(upload_to=upload_location, null=True, blank=True) I have the user enter a value for 'char', and then the value of 'char' is printed on to a file. The process of successfully producing the file is working, however, the the file is outputting to my source directory. My goal is to have the output file 'pdf01.pdf' output to my db and be represented as 'file' so that the admin can read it. Much of the information in the django docs has been focussed on directing the path of objects imported by the user directly, not on files that have been created by m using the user's data. I have been reading mostly from these docs: Models-Fields Models File response objects I have seen it recommend to write to a buffer, not a file, then … -
Django Autocomplete-Light stuck on autocomplete input field

I'm trying to make a feature where a user can click on a category, and then search within that category. My problem is I can't seem to get the category pk in the html. I've fried my brain trying to find a way, but no luck yet. <form class="searchfield" action="{% url 'posts:cat_search' pk= %}" method="get"> <button type="submit" name="button"> <i class="fa fa-search"></i> </button> <input class="searchfield" id="searchbox" name='q' type="text" placeholder="Search"> </form> I need to specify a category pk for the search, but how? I can grab all the category pks, but just not the one for the correct category class PostListView(LoginRequiredMixin, ListView): model = Post def categories(self): return Category.objects.all() def get_queryset(self): return Post.objects.filter(created_date__lte=timezone.now()).order_by('-created_date') class PostCatView(PostListView): template_name = 'posts/post_category.html' def get_queryset(self): result_pk = self.kwargs.get('pk') return Post.objects.filter(label=self.kwargs.get('pk')).order_by('-created_date') class CategorySearchView(PostCatView): def get_queryset(self): result = super(PostCatView, self).get_queryset() query = self.request.GET.get('q') if query: query_list = query.split() result = result.filter( reduce(operator.and_, (Q(title__icontains=q) for q in query_list)) | reduce(operator.and_, (Q(body__icontains=q) for q in query_list)) ) return result -
Annotating djagno queryset not returning annotations using backwards foreign key. Using geodjango
I have a mysterious problem where annotations are not showing up on queryset using backwards foreign key. Using Django 2.2. Models from django.contrib.gis.db import models class Hexgrid_10km2(models.Model): polygon = gismodels.MultiPolygonField(srid=4326) class Reply(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) reply_date = models.DateTimeField() ability = models.FloatField(default = 0) hexgrid_10km2 = models.ForeignKey(Hexgrid_10km2, related_name='replies', on_delete=models.CASCADE, null=True, blank=True) Problem I am first filtering the Hexgrid_10km2 to only those containing Replies as so: most_recent = Reply.objects.filter( reply_date=Subquery( (Reply.objects .filter(user=OuterRef('user')) .values('user') .annotate(most_recent=Max('reply_date')) .values('reply_date')[:1] ) ) ) hex_qs = Hexgrid_10km2.objects.filter(replies__in=most_recent) >>> hex_qs <QuerySet [<Hexgrid_10km2: Hexgrid_10km2 object (197028)>, <Hexgrid_10km2: Hexgrid_10km2 object (197028)>]> I check to see that they do contain replies as so: >>> hex_qs.aggregate(Sum('replies__ability')) {'replies__ability__sum': 2.0} Now the mystery... >>> hex_qs.annotate(avg_ability=Avg('replies__ability')) <QuerySet [<Hexgrid_10km2: Hexgrid_10km2 object (197028)>]> Where is the annotation? Does it have something to do with geodjango which I am using to build the models? I am feeling like a fool. Many thanks for your help as am completely stuck.
