"Request failed with status code 500" when I try opening my products page
This is my first time using redux and django. I click the link to one of my products that takes me to the products page, but I get a 500 error instead. My django server is running in the back and I know it's working because I get an error response in my terminal. I suspect my issue might be my views.py but I'm not sure since I'm not very familiar with django yet.

Overriding method python class of a pip module to update its behavior globally
Using OOP I want to do something like from django.contrib import admin class NavigateFormAdmin(admin.ModelAdmin): def render_change_form(self, request, context, add=False, change=False, form_url='', obj=None): context['next_record_id'] = custom_function_to_calculate(context['obj'].id) res = super().render_change_form(request, context, add, change, form_url) return res And expect that whenever render_change_form of admin.ModelAdmin is called, it should first my overridden method (above) which then should call the original (parent) method. but it makes no difference, because my overridden method never gets called rather on any call to render_change_form the method from original class admin.ModelAdmin is called.

Django - runserver command doesnt do anything
I activate the venv and when I try to run the python manage.py runserver command on VScode powershell it doesnt do anything, no errors, nothing, I enter the localhost to see if the server was activated with no notice but it doesnt appear.

I tried running it on cmd and i couldnt run the activate command this time, apparently I need to use power shell to run linux like commands?

What is the best way to increment these likes and checks model attributes in a callback function using an if-elif-else statement?
I dont want to create two callback functions. I want this callback to execute in a conditional way using an if-elif-else statement. Firstly, will the code work well as it is?

Strange errors using factory_boy and DjangoModelFactory
I've created several factories including a user factory that looks like so class UserFactory(factory.django.DjangoModelFactory): class Meta: model = models.User django_get_or_create = ('phonenumber',) uuid = factory.Faker('uuid4') email = factory.Faker('email') phonenumber = factory.Sequence(generate_phone_number) I'm using the django unit test TestCase model like so class ApiV1TestCase(TestCase): def setUp(self): self.user = UserFactory.create() and getting the following error: *** django.db.utils.IntegrityError: duplicate key value violates unique constraint "accounts_user_pkey" DETAIL: Key (id)=(1) already exists. when I run it several times I get a continual error with what looks like a correctly autoincremented ID field, ie. Key (id)=(2) already exists. ... Key (id)=(3) already exists. on each subsequent create() call. If I check the test database, I see that User.objects.all() is empty in all of these cases. Alternatively I'm able to successfully run UserFactory.build() u.save() however this isn't great for obvious reasons (ie. I want to override an auto_now datetime field in some tests) I've also noticed some strange behavior, if I check transaction.get_connection().in_atomic_block from django.db.transaction I get True which seems to indicate somehow that I'm in an atomic block? I'm not sure if this is normal behavior. -

Why does my dependent dropdown form act up?
I am attempting to implement a dependent dropdown form for my project. I want the makes dropdown to be dependent of the year of the vehicle. The models dropdown entries should be dependent on the year and make dropdown entries selected. Finally, the repairs dropdown should be dependent on the year, make, and model selected. However, this is not the case. In my django database, I have two entries titled "Chevrolet" that are connected to years 1980 and 1981 via ForeignKey. Both of these entries are connected to an entry titled "Camaro". Another entry I have stored in my backend database has 1981 as the year, "Ford" as the make (connected to 1981 via ForeignKey), and "LTD Crown Victoria" and "F-150" as models. While the year and makes appear as they should, the other entries do not. I can only get the appropriate models to appear in the dropdown box after I select 1981 as the year and "Ford" as the model. Afterwards, I am able to see the models connected with the 1981 entry for "Chevrolet".

Django - combining querysets from different models and serializing them
I am a newbie trying to build an e-commerce website for fun. Firstly, I take the query parameters from the url, then find the fitting products and then try to find the corresponding images.

Django reverse accessor clash - multiple uses of a model
I have two models, Photo and Story. The Story model uses the Photo a couple different ways - for a thumbnail, a header photo, and a gallery. I am storing an optional Story reference in the Photo model. This was causing a E.304 error: (fields.E304) Reverse accessor for 'stories.Story.header_image' clashes with reverse accessor for 'stories.Story.thumbnail'. I added related_name='+' to both the thumbnail and header_image fields. This disallows the backward relation and got rid of my reverse accessor clash issue. I was able to set up a PhotoInline in the Django admin, but also realized that there is now no way for a user to add a thumbnail or header_image inline - the typical "edit" and "add" options aren't available. What do I need to change about my models or admin config to allow for that? I tried changing the related_name params to name the relationships instead of disallowing them, but that didn't seem to help - not sure if I would need to use those values somewhere. class Story(models.Model): title = models.CharField(max_length=200) author = models.CharField(max_length=200) thumbnail = models.ForeignKey('Photo', on_delete=models.CASCADE, null=True, blank=True, related_name='+') header_image = models.ForeignKey('Photo', on_delete=models.CASCADE, null=True, blank=True, related_name='+') content = tinymce_models.HTMLField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) created_by = … -
