Reset Avatar ImageField to Default when User Clear Avatar Through DRF or Django Admin
I have django model ImageField called avatar. I want to enable user clear their avatar, so Blank = True. The problem is when user clear their avatar, the ImageField path is now empty. What i want is, the ImageField back to default. models.py class Profile(models.Model): AVATAR_UPLOAD_TO = "account_avatar/" DEFAULT_AVATAR = "default.jpg" user = models.OneToOneField(CustomUser, on_delete=models.CASCADE) avatar = sorl.thumbnail.ImageField(upload_to=AVATAR_UPLOAD_TO, default=AVATAR_UPLOAD_TO+DEFAULT_AVATAR, blank=True, null=True) I see some related questions Django ImageField overwrites existing path when empty. But the behaviour is not exactly what i want. This answer required the user to upload new avatar, so user couldn't clear their avatar. Another related questions Django - How to reset model fields to their default value?. But i can't implement the save() method on my models I have tried to implement save() method on Profile model, but it don't work as expected def save(self, *args, **kwargs): if not self.avatar.name: setattr(self, 'avatar.name', self.avatar.field.default) super().save(*args, **kwargs) # Call the "real" save() method. I am new to Django and Django Rest Framework. Please help me, i stuck with this problem from a few days ago. Could you please help with my problems. Thanks in advance! -
Share env across GitHub Actions workflows
I have a GitHub Action (test-python.yml) intended to test a Django application. It utilizes the env tag like so towards the top of the file: env: SECRET_KEY: test DEBUG: False ... I want to make another workflow - not a job in the same workflow - that is reliant on the same variables. I could obviously just make another file for said workflow and copy the env however this seems slightly flaky, I'd rather somehow share the env variables across numerous workflows so I only have to keep it up to date in one place. Is there a way to do this? Thank you in advance! -

What is the best way to parse this request.data in drf, when the request is form-data?
I have this form which sends an image along with some other data. I am using django-rest-framework in the back end. I need to take out couple of fields from this form input and do some operations and use the remaining fields to send to my ModelSerializer for posting the form data. What is the best way to achieve this? <QueryDict: {'areaName': ['Mall-24F'], 'devices': ['[\n {\n "name": "device_001",\n "coordinates": [\n 23,\n 56\n ],\n },\n {\n "name": "device_002",\n "coordinates": [\n 24,\n 57\n ],\n },\n {\n "name": "device_003",\n "coordinates": [\n 25,\n 58\n ],\n }\n]'], 'floorMap': [<InMemoryUploadedFile: 1653650801973.png (image/png)>]}> This is how request.data looks like. What I have tried doing is context = request.data context["name"] = context.pop("areaName")[0] context["floor_map"] = context.pop("floorMap")[0] Basically I only want "name" and "floor_map" to be sent to ModelSerializer. I have read that request.data is immutable, but here it is mutable. I think I am missing something. -

Django simplejwt validate token
I am implementing authentication with Django simpleJwt, and have a question. I want to create something with Client's jwt token. I use methods provided from simpleJwt to validate and decode jwt token. class AccountBookAPIView(APIView): def post(self, request): jwt_authenticator = JWTAuthentication() raw_access_token = request.META.get('access_token') validated_token = jwt_authenticator.get_validated_token(raw_access_token) user = jwt_authenticator.get_user(validated_token) However, I doubt that some methods really validate token. So I checked the method's implementation.

Creating a simple multiple users app in Django
So I've created 3 different users: admins, developers, and project managers.

Because when I input the same user details as the one I just created into the login form, it throws up the built-in error message, 'A user with that user name already exists' I'm not sure how to proceed from here.

Django Admin doesn't recognise blank=True in model

This is where I'm having trouble: If the query does not match the name of an encyclopedia entry, the user should instead be taken to a search results page that displays a list of all encyclopedia entries that have the query as a substring. For example, if the search query were ytho, then Python should appear in the search results. This is the view: def search(request): if request.method == 'POST': search_title = request.POST['q'] content = converter(search_title) if search_title is not None: return render(request, "encyclopedia/entry.html", { "entry": content, "entryTitle": search_title }) else: entries = util.list_entries() search_pages = [] for entry in entries: if search_title in entries: search_pages.append(entry) return render(request, "encyclopedia/search.html",{ "entries": search_pages }) And the HTML: <form action="{% url 'search' %}" method="POST"> {% csrf_token %} <input class="search" type="text" name="q" placeholder="Search Encyclopedia"> </form> Traceback: Traceback (most recent call last): File "C:\Users\anshi.virtualenvs\storefront-bp3LZ8Cr\lib\site-packages\django\core\handlers\exception.py", line 55, in inner response = get_response(request) File "C:\Users\anshi.virtualenvs\storefront-bp3LZ8Cr\lib\site-packages\django\core\handlers\base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "D:\Python\Py Projects\CS50 attempt 00\wiki\encyclopedia\views.py", line 70, in search content = converter(search_title) File "D:\Python\Py Projects\CS50 attempt 00\wiki\encyclopedia\views.py", line 19, in converter html = Markdowner.convert(content) File "C:\Users\anshi.virtualenvs\storefront-bp3LZ8Cr\lib\site-packages\markdown\core.py", line 248, in convert … -
Adding widgets to django form does not update the forms
So I have a login form for which I am trying to edit the css attributes. However I cannot seem to find the correct solution. Below is my views.py, forms.py and html snippet accordingly. def index(request): context = {} if request.method == 'POST': form = LoginForm(data=request.POST) context['form'] = form logging.debug(form.is_valid()) logging.debug(form.cleaned_data) logging.debug(form.errors) if form.is_valid(): logging.debug("form valid") username = form.cleaned_data.get('username') password = form.cleaned_data.get('password') if authenticate(username, password): logging.debug("logged IN") messages.success(request, f' welcome {username} !!') return redirect('loggedIn') else: logging.debug("wrong!") messages.info(request, f'Password or Username is wrong. Please try again.') form = AuthenticationForm() return render(request, "index_logged_out.html", {"form": form}) class LoginForm(forms.ModelForm): class Meta: model = WebsiteRegistrant fields = ['username', 'password',] widgets = { 'username': TextInput(attrs={ 'class': "form-control", 'style': 'max-width: 300px;', 'placeholder': 'Username' }), 'password': PasswordInput(attrs={ 'class': "form-control", 'style': 'max-width: 300px;', 'placeholder': 'Password' }) } <form method="POST"> {% csrf_token %} <center> <div class="form-group" style = "margin-bottom: 10px; width: 300px"> {{ form.password }} </div> <div class="form-group" style = "margin-bottom: 10px; width: 300px"> {{ form.password }} </div> <button class="btn btn-primary btn-block fa-lg gradient-custom-2 mb-3" type="submit" style="width: 300px;">Login</button> </center> </form> Any idea what I am doing wrong or what I could fix in order to add the class name and attributes as I have defined in the form widget? Thanks
