Cannot have a SlugRelatedField to a FileField in a DRF Serializer?
I have a Model w/ a foreign-key relationship to another Model w/ a FileField. I am unable to serialize the 1st model using a serializer w/ a SlugRelatedField to the file of the 2nd model. Here is some code: models.py: class Foo(models.Model): name = models.CharField(max_length=100) bar = models.ForeignKey(Bar, blank=True, null=True) class Bar(models.Model): file = models.FileField(blank=True, null=True, upload_to="some_path") serializers.py: class FooSerializer(serializers.ModelSerializer): class Meta: model = Foo fields = ("name", "bar") bar = serializers.SlugRelatedField(read_only=True, slug_field="file") But when I try to serialize an instance of Foo I get the following sort of error: UnicodeDecodeError at /api/foo/1/ 'utf-8' codec can't decode byte 0xb5 in position 1: invalid start byte Any suggestions? -
Django: Move columns, fields from Child Model to Parent Model?
I currently have a Parent model and a few Child model classes that descend from it. Something like this: class ParentClass(django.db.models.Model) , class ChildClassA(ParentClass) , class ChildClassB(ParentClass) There are several fields that only exist currently on one of the child classes that I would like to exist on all of the child classes. Let's call those fields FieldX, FieldY, and FieldZ. One way I could handle this is by copying FieldX, FieldY, FieldZ to all of the child models. Which isn't a bad solution but is kind of annoying. Is there a good way to move the column/field to the ParentClass? Originally I was going to do it with three migration files: the first migration file would add the columns to the parent class, the second migration file would copy data over, the third would remove the columns from ChildClassA. However, that didn't work. Because Django is smart enough to detect that I was trying to add the same field name to the Parent Class that already exists on one of the Child classes. It raised a n exception for that: django.core.exceptions.FieldError: Local field 'FieldX' in class 'ChildClassA' clashes with field of the same name from base class 'ParentClass'. Instead … -

Django Inline Formset Field Required/Not Required Setting in View
How do I change a field of a inline formset from not required to required in the view? For example, for a form, it would be form.fields['field name'].required = True How do I replicate this setting for an inline formset? I tried formset.fields['field name'].required = True, but was given the error, 'formset' object has no attribute fields. -
How to use django selenium testing in GitHub actions?
I am creating a Django project and I have created a test case that inherits from django.test.LiveSeverTestCase (so it uses selenium): from django.test import LiveServerTestCase from selenium.webdriver.chrome.webdriver import WebDriver class FrontEndTestCase(LiveServerTestCase): @classmethod def setUpClass(cls): super().setUpClass() cls.selenium = WebDriver() cls.selenium.implicitly_wait(10) # Get the URL cls.selenium.get('http://127.0.0.1:8000/vota/') # Add CSRFToken cls.selenium.add_cookie({'name': 'csrftoken', 'value': '1cY4Yb3SljOqj9tUndW1YlIokNOD8tNc2MSU5iKNvsZW8co9WoOOCVGd5RFzxD8P'}) # Define page sections cls.choose_comps = cls.selenium.find_element_by_id('choose-comps') cls.poll = cls.selenium.find_element_by_id('poll-container') cls.end_table = cls.selenium.find_element_by_id('table-container') cls.navs = cls.selenium.find_elements_by_class_name('nav-link') @classmethod def tearDownClass(cls): cls.selenium.quit() super().tearDownClass() The tests are irrelevant to my problem, so I won't include them for the sake of longness. As you probably realize, for this test case to work, I have to start the server with python manage.py runserver. The problem here is that I want to use all these tests in GitHub Actions, and so far, I have, until creating this testcase. Since I have to start the server first, I made a new step in the job. But this step never ends since the server will always be listening for further requests. I also have to install somehow a chromedriver, a step I don't know how to do. Here is my ci.yml file: name: Testing on: push jobs: test_vote: runs-on: ubuntu-latest services: postgres: image: postgres:10.8 env: POSTGRES_USER: postgres … -

My views.py is returning null from django admin object
I would really appreciate some help on this because I'm completely stuck. I've started up a simple django app (trying to make an instagram clone).

Is their a straightforward way to limit the number of updates of a certain field in a django model?
For example i use the extended user model called "profile" and in the profile i have many fields describing the using. what i want is that the user choose whether he is a business user or a regular customer on the web site. but once this field is updated it cannot be updated again, in which the field appears in the profile edit form but as non-editable field. What is the best way to do that? I thought of using an additional field in the database where i include an "update date" and if this field is not null then the user cannot update. but it seems to me too much coding for this small feature.

How to use a Formset with Django_Tables2

How to keep the API running and also Consume Pika (RabbitMQ) parallelly

How do you format a Django datepicker as ISO 8601?
We need to display dates in ISO 8601 (yyyy-mm-dd) format throughout our Django site. The dates that we are getting from the database show correctly, however date pickers do not. When I run the django test server in ubuntu, the datepicker appears to use the locale that the OS is set to. When I run the same code in Windows, it uses dd/mm/yyyy. The various input_formats args appear to be getting overridden somehow, even though I have set them everywhere I can find. Is it possible to force datepickers to display yyyy-mm-dd regardless of client settings? If so, how? Here is the code we have so far. forms.py ... class DateInput(forms.DateInput): input_type = "date" input_formats = ["%Y-%m-%d"] options = { "format": "%Y-%m-%d", "autoclose": True } class RegistrationForm(forms.Form): full_name = forms.CharField(max_length=255, required=True) preferred_name = forms.CharField(max_length=255, required=False) email = forms.EmailField(required=True) password = forms.CharField( max_length=255, required=True, widget=forms.PasswordInput, help_text=password_validation.password_validators_help_text_html(), ) birth_date = forms.DateField(required=True, widget=DateInput, input_formats=["%Y-%m-%d"]) ... settings.py ...

How to test Django messages for a Class Based FormView?

CustomerNoID = models.ForeignKey('Customers', on_delete=models.CASCADE) def __str__(self): return str(self.ID) and my view: def add_customer_view(request): user_id = request.user.id last_customerno = Customers.objects.filter(UserID=user_id).order_by('CustomerNo').last() if not last_customerno: # return '0001' last_customerno = 1000 if last_customerno == 1000: customerno_int = 1000 else: customerno_int = last_customerno.CustomerNo + 1 # if this is a POST request we need to process the form data if request.method == 'POST': customer_form = CustomerForm(request.user.id, request.POST) customer_address_form = CustomerAddressesForm(request.user.id, request.POST) if customer_form.is_valid(): new_customer = customer_form.save(commit=False) new_customer.save() if customer_address_form.is_valid(): new_address = customer_address_form.save(commit=False) new_address.CustomerNoID = new_customer new_address.save() return HttpResponseRedirect('/backend/kunder/') else: customer_form = CustomerForm(request.user.id, initial={'CustomerNo': customerno_int}) customer_address_form = CustomerAddressesForm(request.user.id) return render( request, 'backend/add_customer.html', { 'title': 'WestcoastShop - Backend', 'customer_form': customer_form, 'customer_address_form': customer_address_form } ) But just the Customer is creating not the address I think the form is missing the CustomerNoID and I think I got the right way but after 6 hrs I give up maybe here is a smart guy how finds the error. regards. -
Python / Django - Generating API Documentation - Not using Django Rest
I am working on a Django project that does not use Django Rest On top of this code base I am trying to build a framework to autogenerate swagger documentation From this S.O. Post I am able to get the available Urls: from django.urls import get_resolver urls = get_resolver().reverse_dict urls is a MultiValueDict, here are the first few items in the Dict: MultiValueDict: { <function create_demo at 0x10f6a3820>: [( [('api/v1/create-demo', [])], 'api/v1//create\\-demo$', {}, {} )], 'create_demo': [( [('api/v1/create-demo', [])], 'api/v1/create\\-demo$', {}, {} )], <function users_detail at 0x10f67d280>: [( [('api/v1/users/users/%(user_id)s', ['user_id'])], 'api/v1/users/users/(?P<user_id>[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})$', {}, {'user_id': <django.urls.converters.UUIDConverter object at 0x10bc3c6a0>} )], 'users_detail': [( [('api/v1/users/users/%(user_id)s', ['user_id'])], 'api/v1/users/users/(?P<user_id>[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})$', {}, {'user_id': <django.urls.converters.UUIDConverter object at 0x10bc3c6a0>} )] It appears the keys for this dict are a reference to a view function, followed by the url "name" for that function, and the values are lists containing the relative url path and params. My thought is to loop through each function reference and create an entry for the swagger doc. Inside each view function, I will define vars named RequestSchema and ResponseSchema. Ideally I can access those vars, from the function reference, and add that data to the swagger doc as well. The goal is to have documentation that …
