The profile_pic and profile_bio do not get updated in Update View in Django
So, I am trying to create a Profile Update Form. My problem is that my form updates every field except profile_pic and profile_bio. However, I have updated them successfully directly through the PostgreSQL admin. Most of the answers I found for this problem were to include enctype="multipart/form-data" in the template tag, but I have it already. How do you think I can resolve this issue? This is the Profile Model class Profile(models.Model): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) profile_pic = models.ImageField(null=True, blank=True, upload_to='images/profile/') profile_bio = models.TextField(null=True, blank=True) def __str__(self): return str(self.user) This is the form for Profile Update class EditProfileForm(forms.ModelForm): class Meta: model = Profile fields = ['first_name', 'last_name', 'username', 'email', 'profile_bio', 'profile_pic'] first_name = forms.CharField(max_length=100, widget=forms.TextInput(attrs={'class': 'form-control'})) last_name = forms.CharField(max_length=100, widget=forms.TextInput(attrs={'class': 'form-control'})) username = forms.CharField(max_length=100, widget=forms.TextInput(attrs={'class': 'form-control'})) email = forms.EmailField(widget=forms.EmailInput(attrs={'class': 'form-control'})) profile_bio = forms.CharField(widget=forms.Textarea(attrs={'class': 'form-control'})) password = None This is the View that is supposed to update the profile, it updates all the field successfully except profile_bio and profile_pic class UserEditView(UpdateView): form_class = EditProfileForm template_name = 'registration/edit_profile.html' success_url = reverse_lazy('home') def get_object(self): return self.request.user The registration/edit_profile.html Template {% extends 'base.html' %} {% block title %} Edit Profile {% endblock %} {% block content %} <div class="d-flex justify-content-center"> <div class="card" style="width: … -

Django: API with accumulated data
I am new to python and want to implement an API with accumulated data. I've seen a lot of information about the possibility to browse the database with the django rest framework but I cannot find the right solution to view data which is analyzed or summarized. For example, I have data about some newspaperarticles: articles: [ { name: "test 1", views: 10000 }, { name: "test 2", views: 20000 }, { name: "test 3", views: 30000 } ] I want to show analyzed data like summary: { name: "articles", sum_views: 60000, article_count: 3 } What would be the best practice if I want to use django and the django rest framework? -

Django/Rest Framework Nest Serialization
I'm having a bit of trouble with implementing the serialization for my server. It is a host to demonstrate homomorphic encryption. Storage on the server consists of integers (really two integer tuples (X,q)), which are tied to a single set, sets are tied to sessions, sessions are tied to users... sets & sessions can both be posted. Posting a set includes the user_id, session_id and multiple integers in the request. Posting a set includes the user_id, session_id, then multiple sets in the request. Also, for a set the server generates an ID and sets that value for all integers in the set, and includes it in the response. Ideally, the user_id and session_id are going to be put in once in either type of request. So for a session post, each set does not have the user_id, session_id, but for a set post the set does have those values. For get requests, similar idea... one instance of user_id, session_id, and this time set_id because it was created in the post. A user can request a set or session in the GET request as well. I understand the basic idea of serialization, but I have trouble when nesting comes into play. … -
Simultaneous authorization of the administrator in the admin panel and on the site
When logging in through the admin panel, the administrator simultaneously logs in to the site and in the admin panel, how can I fix this, please tell me? The problem is that when I go on behalf of the admin in the admin panel, authorization occurs on the site that I am developing, and I do not need it. I would like the authorization to be performed separately on the site(for users) and on the admin panel(for admin).(DJANGO).Please help me with this question ??? -
Django - Trying to keep track of user's cart
I have a cart where I have two fields that I use to connect to a user. One is User, I use that if user is logged in. Other is session, this is used to keep track of logged out users. It uses session_key. Now the problem I am facing is that when a user logs in the cart disconnects because the session_key has changed. I know that I can use cookie to identify the browser or client. But I am not able to find an example of Django's set_cookies being used with JsonResponse(AJAX call). It is only for HttpResponse. I think I could use either of these two ways, if possible. Set cookie through AJAX Or Set cookie when user visits website. I want this with ability that no matter which page the user visits at fist the cookie should be set on that visit. Does anyone have a resource or example to achieve this? Thank you -

How do you change django widget select attrs?
I'm trying to add new attributes to this ChoiceField so with help of ddslick() it should display images instead of text, but I'm unable to do so, I've tried declaring it explicitly before and after the meta class or simply as an normal widget, but without success, neither the generated <select> or <option> tags changed any of it's attributes, I was wondering if there's anything else that I can try. class MemoryForm(ModelForm): cover_image=(ChoiceField(widget=Select(attrs={'class': 'asdf'}))) class Meta: model = Memory fields = [ "title", "description", "date", "location", "accurate_date", "accurate_month", "accurate_day", "cover_image", ] labels = {"title": "", "description": "", "date": "", "location": ""} widgets = { "title": TextInput( attrs={"placeholder": _("Enter a title"), "class": "only-bottom"} ), "description": TextInput( attrs={ "placeholder": _("Add a description (optional)"), "class": "only-bottom", } ), "location": TextInput( attrs={"placeholder": _("Enter a location"), "class": "only-bottom"} ), "date": HiddenInput(), "accurate_date": HiddenInput(), "accurate_month": HiddenInput(), "accurate_day": HiddenInput(), "cover_image" : Select( attrs={"data-imagesrc": "/static/media/images/cherryimage/e2e4a952-e949-4b97-8597-eebd9bd445d5.jpg"} ), } -

Django view decorator exception does not prevent view execution
A docorator that is suppose to send a 403 page let the rest of the view execute. request-token library provides a view decorator. If provided token is expired an exception is raised. Documentation says if such exception is raised, 403 response is send. When token is expired, decorator do raise an exception but the rest of the view is still executed and no 403 response is send. @require_POST @use_request_token(scope="my_scope") def my_view(request): print('after raised') # this code is executed return JsonResponse({ 'status': 'everything is fine !!!'}) # Wrong ! raise ExpiredSignatureError('Signature has expired') jwt.exceptions.ExpiredSignatureError: Signature has expired after raised Is this behavior normal ? How can I prevent view being executed if an exception is send by decorator ? -
Django form with fields and Ajax dependent Dropdown list from 4 different models
I want to insert data to the DB tables using Django ModelForm, the form is populated from 4 different Models. My Models: Region: name, District: name and region foreign key, Address: street, address, and district foreign key, Property: name, staff_manager(User model foreign key), and address foreign key. (All models' fields are set not to be blank) My forms: PropertyForm: fields = ['name', 'staff_manager'], AddressForm: fields = ['street', 'address'], for Region and District fields, I've used a dependent dropdown list with the help of Json, Ajax and Js, where districts will be shown depending on a selected region. My Challenge/Objective: I want to be able to simultaneously create a Property, and Address (insert it's street, address & district_id ---> which will be selected depending on region choosen from the form), all from a single form. My Models: Region & District Models, Address & Property Models My Form: ModelForm, Form HTML, Form-Frontend My Views: View, Region & District Json View Dependent Dropdown list Ajax & Js: Region Ajax Javascript Any help, insight or different perspectives of achieving my objective will be greatly appreciated.

Overriding simple-jwt's TokenObtainPairSerializer to implement 2FA
I am currently trying to implement 2FA in my Django Application. The first thing I've done is to modify the Meta class in the UserSerializer class to add two fields enabled (indicates if 2FA is enabled for a user) and secret_key (the key to generate OTP, that is shared to the user when he enables 2FA). To minimally modify the login flow, I've modified the form that is sent to generate the access tokens to include a new field "otp". The user can fill it or not, and the backend will check if the user has 2FA enabled, and if yes, if the OTP is correct. Without 2FA, the login is simply a POST request with body {"username": usr, "password": pwd}. This has become a POST request with body {"username": usr, "password": pwd, "otp": otp}. If a user user hasn't enabled 2FA, he can simply leave the opt field blank. My urls.py looks like this: path("api/token/", TokenObtainPairView.as_view(), name="token_obtain_pair") My idea is to override TokenObtainPairView to adapt to the new request. From what I've found, I have to change the validate method, but I don't really have a clue as to how to do that. I probably would have to get … -
