Cross domain cookie not being sent in the subsequent request even when it is set in the last response
I have my app at app.exampledomain.com which is in reactjs(axios for api call) and it is consuming api from api.exampledomain.com. in the response to an api call the server at api.exampledomain.com is setting the cookie in the response header like: sessionid=fyytiannsv29edvn4zgkr1orfcfscyh3; expires=Sat, 26 Mar 2022 14:02:49 GMT; HttpOnly; Max-Age=604800; Path=/ but in the subsequent requests from app.exampledomain.com the cookie is not being sent in the request header and again set cookie is received in the response header. moreover, the cookie that api sets is not visible in the cookies tab of the browser. I think the browser is rejecting the cookie sent by the server as both the client and server have different subdomains/sites (api.exampledomain.com vs app.exampledomain.com). I want to set cookies having sessionid and this sessionid to be sent in request headers cookies in subsequent requests from app to api. if i make SESSION_COOKIE_DOMAIN = '.example.com' i am able to see the cookie in the browser with domain '.exampledomain.com', still it is not being sent in the subsequent requests and new sessionid is being sent in set cookie in response headers. I tried modifying SESSION_COOKIE_SAMESITE, SESSION_COOKIE_SECURE but it did not help. -
Implementing OAuth Flow with Django+DRF+Vue with JWT
I'm trying to implement Dropbox OAuth Flow on my project, it's working fine without DRF and Vue, when i moved on Vue for my frontend, things get messy.

Render DjangoCKEditor in React CKEditor
I would like to know whether it is possible to render RichTextField from Django CKEditor using CKEditor from ckeditor5-react ?

But I have no idea how do I replicate Django CKEditor using React CKEditor. -
Model.Form Queryset
I have a model.form which I need to apply a queryset to filter the choices available within a select field. class AnswerForm(ModelForm): class Meta: model = ProjectQuestionnaireAnswer fields = ('answer','notes') widgets = { 'answer': forms.Select(choices = Choice.objects.filter(question_id = 1),attrs={'class': 'form-control select2'}), 'notes': forms.Textarea(attrs={'class': 'form-control','placeholder': 'Add notes to question here'}), } class Choice(models.Model): question = models.ForeignKey(ProjectQuestionnaireQuestion, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) def __str__(self): return str(self.choice_text) I'm not sure how to write the query to only return the choices related to the question. I've tested with choices = Choice.objects.filter(question_id = 1) which does return me the choices for question 1, but need it for each question? And then how do I present this in my template? {{ form.answer.choices }} ?? Thanks -

Why must I use Function-based views if there is Class-based?
From the Django Documentation In the beginning there was only the view function contract, Django passed your function an HttpRequest and expected back an HttpResponse. This was the extent of what Django provided. Early on it was recognized that there were common idioms and patterns found in view development. Function-based generic views were introduced to abstract these patterns and ease view development for the common cases. The problem with function-based generic views is that while they covered the simple cases well, there was no way to extend or customize them beyond some configuration options, limiting their usefulness in many real-world applications. Class-based generic views were created with the same objective as function-based generic views, to make view development easier. However, the way the solution is implemented, through the use of mixins, provides a toolkit that results in class-based generic views being more extensible and flexible than their function-based counterparts.strong text -

Using a local Django app without packaging it
I'm planning to write an add-on app for an existing django app. The primary app is running smoothly via docker-compose, and I've remoted into the container via the vscode remote-containers extension. Add-ons are installed like most any other django app, pip install APPNAME, append to INSTALLED_APPS, migrate, collectstatic, restart server. I can create a directory anywhere in the container, where the add-on will exist and be developed, but I'm looking for a way to make the app visible from that directory so I can include it in the primary app's INSTALLED_APPS list. Is this possible, or would I have to create the app inside the primary package's site-packages directory alongside its own sub-apps for this to work? -

Restricting view by model permissions fails in django
Very basically I have a model member and want to restrict searching members to allowed users. I use the following in the corresponding view if request.user.has_perm('view_member'): context['user_list'] = get_user(q) Sadly this does not work even if a) I give a user this permission via the admin interface b) in my tests that look a bit like the following def test_user_search_view(self): self.client.login(username='testuser0', password='12345') # this is a user that was given the permission (see below) response = self.client.post(reverse('library:search'), data={'q': "Müller"}) # Check our user is logged in self.assertEqual(str(response.context['user']), 'testuser0') # Works self.assertContains(response, "Max") # Fails, but max shouls be there For further tests I used the debugging mode of PyCharm to go into the test. In the console I then executed the following >>> permission_view_user = Permission.objects.get(codename='view_member') >>> test_user0.user_permissions.add(permission_view_user) >>> test_user0.save() # For good luck >>> user = get_object_or_404(User, pk=test_user0.pk) >>> user.has_perm(permission_view_user) False I would expect true here.
