Updating Form.intial does not change intial value in Django template
Goal I want to retain the query when a search result renders. Here is an example where the search bar contains stackoverflow on the results page. Failed Solutions These are minimal code examples # search_results.html <form action="/search" method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Search"> </form> # views.py ... class SearchView(TemplateView): """Search view""" def get_context_data(self. **kwargs): context = super().get_context(**kwargs) user_query = self.request.GET.get('q', None) form.initial = {'user_query': user_query} return context The first time I search in the browser, the template renders as expected. If I search foo the following is rendered <form action="/search" method="post"> <input type="text" value="foo" name="search"> <input type="submit" value="Search"> </form> But searching a second time doesn't change the string in the search bar.

Django Rest Framework request header based permission
I'm building a Django app with Django Rest Framework to host it on my organisation's domain. The domain implements a custom authentication protocol. When someone accesses the domain, say to app1.domainname.com, they are redirected to the organisation's login page (login.domainname.com) and they have to log in with their staff account. After the user is authenticated, the user is redirected back to their initial destination (app1.domain.com). The information of the user is then stored in some custom header fields of the HTTP request sent to the app. E.g. GET / HTTP/2 Content-Type: User-Agent: ... ... X-Username: johndoe1 X-Firstname: John X-Lastname: Doe X-Email: johndoe@domainname.com etc. I'm trying to implement custom permission for my REST API that looks for these fields in the headers, and then authorise the user based on their user information. This is what I'm currently having: from rest_framework.permissions import BasePermission allowed = ['johndoe1', 'dicksmith2', 'username3'] class CutomPerm(BasePermission): message = "You don't have permission to access this object" def has_object_permission(self, request, view, obj): print(request.headers) username = request.headers['X-Username'] return username in allowed But when I run the server, it seems like the custom headers are passed through to the backend. For some requests they are, but ultimately the user is not … -
RecursionError when trying to save image

Concurrent.futures.Executor.map() is only running fragments of passed function

React frontend not receiving response from Django HttpResponse after successful request
I'm working on an application with a React frontend and Django backend. The frontend request is hitting the backend (and updating the db) but a response is not being returned to the frontend. I'm new to both Django and React so I haven't been able to debug it. React Frontend var csrftoken = Cookies.get('csrftoken') let headers = { "X-CSRFToken": csrftoken, "Content-Type": "application/x-www-form-urlencoded" }; const qs = require('qs'); axios.post('/api/thing/new/', qs.stringify({thing_text: thing.thing_text}), {'headers': headers}) .then((result) => { console.log(results) }); Django Backend class ThingForm(ModelForm): class Meta: model = Thing fields = ['thing_text'] def thing_create(request): form = ThingForm(request.POST or None) if form.is_valid(): form.save() return JsonResponse({'foo':'bar'}) I've also tried returning a response with return HttpResponse(status=204) to no avail. This is resulting in an error, Uncaught (in promise) ReferenceError: results is not defined Which I interpret as nothing being returned to the frontend (though I could be wrong). Again, I know the backend is receiving the request because a record is created in the db. Is there anything I should try to debug this? -

Django: How to retrieve in an AJAX POST request the value of two different variables?

The value of d1 is properly captured but d2 (so result_2) shows "[]". How can I capture the two variables? -

Test login protected page with permissions in django (pytest)
I am trying to test a view which only shows a template thus far. To access the view the user needs the permission 'projects.can_view'. I am trying to create a user with this permission in the test db using a fixture, then I am trying to log a client in with the username and password of my user in the db. I try to visit the view but I get a 302 error (redirect to login view.) I can verify that I actually pass the permissions correctly: My fixture: @pytest.fixture() def create_users_with_permissions(): User = get_user_model() u = User.objects.create( username="test", password="pass", ) permission = Permission.objects.get(name='Can view project') u.user_permissions.add(permission) u = User.objects.get(username='test') print(u.has_perm('appname.view_project')) return u I query the user again to delete the permissions cache like explained in the doc (https://docs.djangoproject.com/en/3.0/topics/auth/default/). When I print out print(u.has_perm('appname.view_project')) it returns True. Thus I assume I have a user with this specific permission created. Now I pass the fixture to my test and log pytests client-fixture in: def test_xyz( self, client, create_users_with_permissions ): client.login( username=create_users_with_permissions.username, password=create_users_with_permissions.password ) url = reverse('urlforview') response = client.get(url) assert response.status_code == 200 This fails with error code: assert 302 == 200 If I create a superuser in the db and … -

Is a defined app_name recommended in urls.py for Django 2?
I'm trying to figure out what the best practices are around writing urls.py files in my Django app. I'm updating an old project to Django 2, and I read in the update documentation that urls.py files should be properly namespaced. A bit of googling suggests to me to define app_name in my urls.py always, so you don't have to manually add the app_name to each url endpoint. Instead you can then access it like ("app_name:url_name"). In my project I have: avatar/urls.py tests/urls.py So in this case, I am not sure how to name them, but for now I've gone with app_name = "avatar" in avatar/urls.py and app_name = "avatar-tests" in tests/urls.py. Do these both need an app_name for proper namespacing? Is it best practice to always have a defined app_name per urls.py? I'm uncertain still if this is required or even recommended. If I've understood correctly, it's just for easier/logical access of the url, not strictly required, but recommended in the sense that it's easier to follow.
