Blocked Set-Cookie in development environment DRF SessionAuthentication + React
I have a very specific question that I haven't found within the many questions regarding this topic. I have a DRF + React web application which I recently changed from Token Authentication to Session Authentication for server side expiration. In production this works great, upon login I receive two Set-Cookies, a session id and a csrftoken. However, in my development environment, the Set-Cookies are blocked as This Set-Cookie was blocked because it had the 'SameSite=Lax' attribute but came from a cross-site response which was not the repsonse to a top-level navigation.. I tried changing the SameSite setting to none, in which case Chrome requires secure cookies, which I don't think is possible in my dev environment. I tried disabling Cookies without SameSite must be secure in chrome://flags. Listing localhost in CSRF_TRUSTED_ORIGINS solves the CSRF, but then the login issue remains. Although I don't think this is relevant, a lot of solutions here mention to add {withCredentials: true} to the requests, this however does not solve my issue as I do receive the Set-Cookie headers, they're just blocked... -

Recreating a file-based POST request from Django-Rest-Framework test in curl
I have a test case using The test library from Django. In my test I have the following: class TestLoadCurve(TestCase): def setUp(self): self.client = Client() self.test_user = User.objects.create_user('test_user', 'a@b.com', 'test_user') self.client.login(username="test_user", password="test_user") def test_post_loadcurve_as_xlsx(self): response = self.client.post( reverse('loadcurves-list'), {'file': open("app/tests/loadcurve_files/loadcurve.xlsx", "rb"), "name": "testuploadloadcurve"}, ) self.assertEqual(response.status_code, status.HTTP_201_CREATED) And the (simplified) endpoint looks like this: class LoadCurveViewSet( mixins.CreateModelMixin, mixins.RetrieveModelMixin, mixins.ListModelMixin, viewsets.GenericViewSet ): ... def create(self, request, *args, **kwargs): up_file = request.FILES['file'] ... return Response(status.HTTP_201_CREATED) This test works. But I want to re-create the POST request that it makes using curl for some documentation. I have only made it so far: curl --user <myuser>:<mypass> -X POST -H --data-urlencode "payload={\"file\": $(cat app/tests/loadcurve_files/loadcurve.xlsx), \"name\": \"curlloadcurve\"}" http://localhost:5100/loadcurves/ Using the debugger I am able to stop the processing at the line up_file = request.FILES['file'], at which point I realize that both request.FILES and request.data are both totally empty. Am I not making the POST request correctly? I was following this answer Python version is 3.6.9 Django version is 3.1.3 -
Django - perform action on Profile while creating User
I was looking for solution for my problem here, but it didnt solve my problem. I want to create user's profile while their signing up. To signup I use CreateView class UserRegisterView(generic.CreateView): form_class = SignUpForm template_name = 'registration/register.html' success_url = reverse_lazy('login') #this method doesn't work and I get # `Profile.user" must be a "User" instance` def form_valid(self,form): Profile.objects.create(user=self.request.user) My Profile model looks like: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) #rest of fields like bio, social urls etc My main point is to automatically create user's profile when their create their account. What is the best way to solve this? -

error 403 csrf token when using multiple post method with action attribute
i got a page how have multiple POST method , so i used the action attribute in ajax to recognize each of the post method , but when i tried to use it on the form how add a model into the database (client model), it said 403 error invalid or missing csrf token, but when i remove the action and let only the REQUEST.METHOD == 'POST', it work , so i didnt understand why the csrf token is not working when i use the action , i solved the problem by getting directly the values of input form but is better if i use the automated feature of django forms so their is my old code . ajax request: $(document).ready(function(){ var csrfToken = $("input[name=csrfmiddlewaretoken]").val(); //$("#alert-container").hide(); //console.log(csrfToken); $("#btn-submit").click(function() { var serializedData = $("#ClientForm").serialize(); console.log("hey hey clients!"); $.ajax({ url: $("ClientForm").data('url'), data :{serializedData,action: 'client'}, type: 'post', success: function(response) { console.log(response.client.name); console.log($("#ClientList")) } }) $("#ClientForm")[0].reset() }); }); html form : <form class="contact-form" id="ClientForm" data-url="{% url 'addclient' %}" method="POST"> {% csrf_token %} <div class="form-group"> <label for="name" class="sr-only">Name</label> {{ form.name }} </div> <div class="form-group"> <label for="email" class="sr-only">Email</label> {{ form.email }} </div> <div class="form-group"> <button type="button" id="btn-submit" class="btn btn-success btn-md">Add Client </client> </div> </form> View.py: def … -

How to copy encoded password from one Django model into another?
For some reason, I initially save my users to a temporary table, and only later do I copy them to a table that uses Django's User. My question is: How do I copy the password field from the temporary table to the permanent table? Of course I do not keep the password as it is in the temporary table, but use the make_password function of Django. How do I enter it, when it's already encoded, into a password field in Django's user table, without it going through encoding again? Pseudo code for illustration: step one MyTempModel.objects.create(email=email, password=make_password(password)) step two PermanentModelUsedUser.objects.create(email=temp_user.email, password=temp_user.password) -

Django filter duplicates data

Nginx - Django : After restart website doesn't work anymore but keep working for the admin part
I'm a bit embarrassed about this question because something doesn't work correctly and I don't understand why. Let me explain : I'm using all of this with docker. Each one has its own container. I update something on my project (new folder on the repository nothing related to the website) and once my production version (on the server) gets the update, Nginx and Django restart but from this exact moment: my homepage shows me Index of ../. So I tried to restart both containers but it changes nothing and something really strange is that if I go to the Django admin it works! So I don't understand what's happening here ...
