Why does LDAPBackend.authenticate() store user info in custom user model in Django
I'm new to LDAP authentication and going through some of the StackOverflow questions and django-auth-ldap documentation I was able to implement LDAP authentication in my django project. I have a custom user model to store the user information. But my question here is that when we do authenticate using user_id and password why does authenticate store the user info in the custom user model. It also stores the hashed password. I have used LDAPBackend as my authentication backend in settings.py file like this AUTHENTICATION_BACKENDS = [ 'django_auth_ldap.backend.LDAPBackend' ] and for example when we perform the below operation auth = LDAPBackend() user = auth.authenticate(request, username=user_id, password=user_password) the user object is stored in the custom user model. My requirement is here not to store any user information when authenticate happens and not to store any password(be it hashed password). There are some pre-checks I need to do before storing it into user info to the custom user model. But LDAPBackend.authenticate() stores user info as it authenticates. Can anyone please help me on this and clarify what's going on here. Thanks -

Django - upload just picture in model with a POST request
I would like to upload a profile picture with ajax. But even if I don´t send the image with ajax, it doesn´t work. I have the following code in my website: <form action="{% url 'update_profile_pic' %}" method="post"> {% csrf_token %} <input name="profilePic" type="file" accept="image/*"/> </form> The profilePic should be saved in the model: class UserProfile(models.Model): user = models.OneToOneField( User, on_delete=models.CASCADE, primary_key=True, ) profilePic = ProcessedImageField( upload_to=generate_random_filename, processors=[ResizeToFill(150, 150)], format='JPEG', options={'quality': 60}, ) ... The url.py has the correct entry: ... path('update_profile_pic/', views.UpdateProfilePic.as_view(), name='update_profile_pic'), ... The form is like this: class ProfilePicForm(forms.ModelForm): class Meta: model = UserProfile fields = ('profilePic',) And the view should also be correct: class UpdateProfilePic(View): def post(self, request): form = ProfilePicForm(self.request.POST, self.request.FILES) if form.is_valid(): request.user.userprofile.profilePic = form.cleaned_data['profilePic'] request.user.userprofile.save() return JsonResponse({ image_url : request.user.userprofile.profilePic.url }) else: raise Http404(form.errors) But I always get the error "profilePic This field is required.", when I upload a picture. This error comes from the raise Http404(form.errors), so the form is not valid. When I look at the headers in the network tab in google chrome, it shows me this: csrfmiddlewaretoken: sbyaJ8J7COSdC0OUYr4p8ToaarjFrIniDKLT3Lr36PVeTUlc9MEafr77exYVvkXL profilePic: fr.cc38d01b0b77.gif What do I do wrong here? -

Django regex url parsing to calling wrong view
I have a Django 2.2 project (using the rest framework) where I need to call a view function with a url of the following format: /class/students?date=07092019 and I've set up the following url route to handle this url:re_path(r'^class/students%3Fdate%3D(?P<date>\w+)/$',StudentsInClassView.as_view() ,name='student'). The corresponding view function has the following definition: class StudentsInClassView(APIView): def get(self, request, date,format=None): For some reason, whenever I go to url, it gets converted to /class/students/?date=07092019 and a different view, with the url path('nba/students/',StudentsView.as_view() ,name='students'), gets called instead. If I remove the "?date=" from the url and just include the actual date, the StudentsInClassView is called as expected. I've escaped both the question mark and the equal sign but doing so doesn't seem to make a difference. How can I get the "?date=" slug to remain in the url as it is used to call the StudentsInClassView? Is there a different regex that could be used to match the whole url? -

a superior user can change other user's password
as an assignment, i need to create this simple web app using django as the admin, I'll create a "low level" username + password. the salesmanager will then give this username and password to his salespersons. this is a "read-only" username. that means, the salespersons can only read/see the data available on this company webapp, simultaneously using just this one username. this username can't change the password. if one of the salespersons resigns, the password will need to be changed. because the salesperson turnover is rather high, I want the salesmanager to be able to change the password for this username, so i don't have to do it myself everytime. the salesmanager himself will use a different username + password as he has more permissions. how do i use django's change password to work in this situation? thank you -
