Django problem with creating instance of model basing on pre_delete signal
I have a model which represents the archives. Once the main advert has been deleted, it's archives version is being created to later view. I wanted to acomplish it basing on signals. I believe my code is correct but for some reason it does not launch signals. signals.py from django.db.models.signals import post_save, post_delete, pre_delete from django.dispatch import receiver from core.models import Advert, Archive @receiver(pre_delete, sender=Advert) def archive_advert(sender, instance, **kwargs): archives = Archive.objects.create(user=instance.user, title=instance.title, category=instance.category, price=instance.price, quantity=instance.quantity, description=instance.description, image=instance.image) models class Archive(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, blank=True, null=True) title = models.CharField(blank=True, null=True, max_length = 100) category = models.CharField(blank=True, null=True, max_length = 3) price = models.FloatField(blank=True, null=True) quantity = models.IntegerField(blank=True, null=True) description = models.TextField(blank=True, null=True, max_length = 1000) posted = models.DateTimeField(blank=True, null=True) image = models.ImageField(blank=True, upload_to="advert_images") apps.py class CoreConfig(AppConfig): name = 'core' def ready(self): import core.signals -
How to create a form for dealing with multiple django model objects
So I have a model Post with the following definition: class Post(models.Model): post_body = models.TextField() user = models.ForeignKey( to=User, on_delete=models.CASCADE ) published = models.BooleanField( default=False ) schedule = models.DateTimeField( default=timezone.now ) I have created a form in HTML template allowing the user to select the posts he want to send to another website or social media account. Like so: <form> <table class="table table-hover"> <thead> <tr> <th scope="col">Select</th> <th scope="col">Post Body</th> <th scope="col">Published?</th> <th scope="col">Schedule (Editable)</th> </tr> </thead> <tbody> {% for post in posts %} <tr> <td> <div class="form-group"> <input type="checkbox" value="{{ post.id }}"> </div> </td> <td>{{ post.post_body }}</td> <td>{{ post.published }}</td> <td> <div class="form-group"> <input type="datetime-local" class="form-control" name="schedule" value="{{ post.schedule|date:"Y-m-d\TH:i" }}"> </div> </td> </tr> {% endfor %} </tbody> </table> <button class="btn btn-primary" type="submit">Post</button> </form> I want to create a Form in the forms.py in order to process this information (i.e. know which all posts were selected) and then perform further actions (calling other APIs in order to publish these to other sites), also since the field schedule is editable, I want to be able to save that as well. Please help as I cannot think of a possible form for this. -
Inherit models whith seperate primary key in django model

Searching through a ManyToManyField in Django
I have a model that contains a ManyToManyField. It looks like this.. applicable_events = models.ManyToManyField(Event) I am trying to basically search using something like this: if 'Video' in prop.applicable_events.all(): print("here") But it isn't fully working as I expected. I want it to search that applicable_event (which is another model). The applicable_event model contains a field named 'name' which I am trying to search against. If I do something like this print(prop.applicable_events.all().filter(name=cur_event)) It prints <QuerySet [<Event: Video Sign In Started>]> So basically I am trying to find out if the string 'Video' is contained in that. -
Unexpected Behaviour of PasswordResetView which sends too many consecutive emails
My Django 3.0 Project is using the default Django Reset Password view, so in my url.py: path('password_reset', auth_views.PasswordResetView.as_view(), name='password_reset') There is a strange behaviour because when I request reseting the password, the view sends a lot of emails to the email address I introduced (let´s say 37 emails). This happened regardless using SendGrid or AWS SES, so something wrong is happening in the view. I investigated and I think the problem is in the PasswordResetForm class which the view uses to send emails. Such form has a get_users() method, which return matching user(s) who should receive a reset, it retrieves all the active users who provided the email. def get_users(self, email): """Given an email, return matching user(s) who should receive a reset. This allows subclasses to more easily customize the default policies that prevent inactive users and users with unusable passwords from resetting their password. """ email_field_name = UserModel.get_email_field_name() active_users = UserModel._default_manager.filter(**{ '%s__iexact' % email_field_name: email, 'is_active': True, }) return ( u for u in active_users if u.has_usable_password() and _unicode_ci_compare(email, getattr(u, email_field_name)) ) The save() method of the form sends an email to each of the users returned by get_users(). I think my problem is that I registered several users … -

I have a simple Blog app where anyone can add post and comment to post. Comments have forignkey relationship with Post. When I select url patch posts/<post id>/comments it shows all comments instead of the comments from related posts. All other CRUD functions works fine with the project. The Git Link :https://github.com/Anoop-George/DjangoBlog.git The problem occurs in view.py where comment object unable to filter comments which are related to specific posts. class CommentListCreate(APIView): def get(self, request,pk): **comment = Comment.objects.filter()** # I need filter here serializer = CommentSerializers(comment, many=True) return Response(serializer.data) -
Django Rest Framework - Django ORM instance.delete() doesn't delete the instance...?
I have the following API delete view: @action(detail=True, methods=['delete'], permission_classes=[IsAuthenticatedViaJWTCookie]) def delete(self, request, pk=None, *args, **kwargs): queryset = self.get_queryset().get(id=pk) if queryset.user == request.user: queryset.delete() return Response(status=status.HTTP_204_NO_CONTENT) else: response = standardized_json_error_response( message='Artwork Object Could Not Be Deleted', data=[] ) return Response(data=response, status=status.HTTP_401_UNAUTHORIZED) When calling this view from an axios.delete request, I can see that the delete request is being made, and hitting the endpoint. All good so far. Yet, in the listing API view, the target instance to be deleted is still being listed. Doesn't matter how many times that endpoint is refreshed, or how long I wait. What is worse still, is when I call that endpoint again using axios.delete in the front end, for a second time, the record is then permanently deleted? Has anyone experienced such odd behaviour before with Django, or could this be a third party issue? *I have installed django-cleanup...? -
Heroku Debug Flag not stopping django debugging
I'm currently have Django project in heroku but I tried to stop the debug mode but unfortunately it's not working. First I tried to stop it from settings.py DEBUG=False DEBUG = os.environ.get('DEBUG', False) both not helping tried also to set env variable heroku config:set DEBUG=False heroku config:unset DEBUG both also not helping I tried to assign wrong value the debug in settings.py for testing which caused to crash the deployment. Hopefully some one can help with this.
