Django update form with multiple images
I'm trying to implement product update form with multiple images. I have already done the main form but have stucked with following thing: When user want to update image using formset he can use only square images, so i've implemented custom validation for it. But here is the problem: after the validation the form "current" image and "clear" checkbox disappear. Here is what it is: incorrect form after validation Here is how it should be + validation error message (it's not on the screenshot): correct form after validation The only place where the isse could be is following piece of code form.instance = form.cleaned_data.get('id') fixes the problem when after form submission it shows me an uploaded image (which is not valid by the way), because i receive it from form.instance.image.url: class ProductImageUpdateInlineFormSet(BaseInlineFormSet): def clean(self): super().clean() for form in self.forms: if form.cleaned_data and form.cleaned_data.get('image'): try: square_image_validator(form.cleaned_data.get('image')) except ValidationError as ex: form.instance = form.cleaned_data.get('id') form.add_error('image', ex.message) # FormSet for updating product images ProductImageUpdateFormSet = inlineformset_factory(Product, ProductImage, formset=ProductImageUpdateInlineFormSet, fields=['image'], max_num=3, min_num=1, can_delete=False) class ProductUpdateForm(ProductAddForm): def __init__(self, data=None, files=None, instance=None, **kwargs): super().__init__(data=data, files=files, instance=instance, **kwargs) self.image_formset = ProductImageUpdateFormSet(data=data, files=files, instance=instance, **kwargs) self.fields['price'].initial = instance.price -

Build a PoC of OCPP server which can communicate with an EV charger using OCPP protocol
I am new to OCPP protocol and I have the following task involving OCPP protocol which I can not find any documentation about it: build a PoC of OCPP server which can communicate with an EV charger using OCPP protocol.Server should be implemented using Python django. Features needed on server side: Connect an EV charger to server List all connected chargers Authenticate user via RFID Start/stop charging process. I basically do not understand the OCPP server. I think it's like a server that receives the requests from clients and respond them. I also found the python package available in the link here. But I could not find the documentations for this, for example, is there any method to list all connected chargers. Can anyone give me simple demo implementation for this task on Python django? Any help would be aprreciated. -
django receiver only works with superuser status
in my users/models.py I have user creation which works fine. I added this. @receiver(post_save, sender=User) def create_userprofile(sender, instance, *args, **kwargs): up, created = UserProfile.objects.get_or_create(user=instance) if created: logger.debug(f"Created UserProfile for {instance.username} using create_userprofile(*)") up.save() the UserProfile instance it creates only creates with superuser. It doesn't matter I add the user through the normal sign up process or the admin. When I change the status of the user to superuser the receiver is kicked off. I want the receiver code to kick off every time. -
How to add the logged in user email in a field in the model directly without using a view in django
I have a field in my model as shown below uploaded_by = models.CharField(max_length=255, blank=True, null=True, editable=False) This field will store the username (email in this case) of the user who has uploaded the data. As you can see that this is non editable so there is no way the user can edit it. The data has to be entered from the admin pannel. I wanted to know if there is any way to fill this field with the username of the loged in user who is uploading the data. I know if I use the view I can do some thing like uploaded_by = request.user So is there a way to do the same directly in the model so that I can use the admin pannel directly to store the username without using a view. -

How to set token expiration time when using django-rest-authtoken?
I'm using the django-rest-authtoken library (https://github.com/wichmannpas/django-rest-authtoken) to manage my API users. The biggest inconvenience is that the user authentication tokens expire in 24 hours, effectively requiring to perform login every day. Unfortunately I couldn't find a way to change the token expiration time. Any help appreciated. -
Can we create multiple users in Django which edit a single product information?
I am new to Django. I have to work on a project which allows 5 or more users to edit a single value. For example, User1 logs in and modifies the status of a product. The modification should be publicly visible. All groups should now see that okay, User1 has added this information at this time. Now, User2 should also be able to modify it and rest should see it. How can we make this happen? Thank you for your valuable time! -

How to fix "Authentication credentials were not provided "on post request Even on [AllowAny]

But I'm getting the following response on making a post request: { "detail": "Authentication credentials were not provided." } Can anybody describe what might be the problem? Is I have to modify to DEFAULT_AUTHENTICATION_CLASSES from the settings or something else, As I don't want to permit the request on this @api_view. -

Remove group when the user is removed django
I'm new to Django and I've created a registration form where, when a user signs up, it automatically creates a group with the same name as the user's username and puts the new user in it. In this way, every user is inside a unique user group (that happen to have the same name as the user inside it). Now, my problem is that, if I delete the user, the group clearly won't be deleted as well. Is there a way to automatize this process? So, delete user --> delete the group he/she/it was in there? My code views.py @unauthenticated_user def register_user(request): if request.method == "POST": form = RegisterUserForm(request.POST) if form.is_valid(): form.save() username = form.cleaned_data['username'] password = form.cleaned_data['password1'] user = authenticate(username=username, password=password) login(request, user) messages.success(request, "Registration Succesfully") # every user is inside an unique group with its name Group.objects.get_or_create(name=username) group = Group.objects.get(name=username) group.user_set.add(user) user.save() return HttpResponseRedirect('register') else: pass else: form = RegisterUserForm() return render(request, 'authenticate/register_user.html', { 'form': form, }) -
Return one field after creation via post-request in django rest framework

Using User Profile to automatically add to field
