serializer.is_valid returns false with an error that the field is required even though I am passing it
I am building a serializer so that if I post using the following command curl -d '{"food": "test", "portion": 12}' http://127.0.0.1:8000/food it will save to the db. However my problem is serializer.is_valid() returns false with an error that the field "food" is required even though I am passing it. I am unable to change the curl command so how can I make it work? Any help is appreciated. views.py serializer = StockSerializer(data=request.data) if serializer.is_valid(): //save else: print(serializer.errors) //{'food': [ErrorDetail(string='This field is required.', code='required')]} serializer.py class FoodSerializer(serializers.ModelSerializer): class Meta: model = Product fields = ["food", "portion"] Log FoodSerializer(data=<QueryDict: {'{"food": "test", "portion": 12}': ['']}>): food = CharField(max_length=8) portion = IntegerField(required=False) -
How to Update field of Django model based on another model with foreign key relation
I have two models Betslip and Bet,I want to update value of Betslip.settled_status to 'Lost', if Bet.settlement_status is 'half_lost' or 'lost', can anyone create a method for it ? class Betslip(models.Model): SETTLED_STATUS_CHOICE = ( ('InGame','InGame'), ('Won','Won'), ('Lost','Lost'), ('Refunded','Refunded') ) settled_status = models.CharField(choices=SETTLED_STATUS_CHOICE,max_length=30) class Bet(models.Model): SETTLEMENT_STATUS_CHOICE = ( ('','select'), ('won','won'), ('lost','lost'), ('refund','Refund'), ('half_won','half_won'), ('half_lost','half_lost'), ) settlement_status = models.CharField(choices=SETTLEMENT_STATUS_CHOICE,max_length=30,) betslip = models.ForeignKey(Betslip,on_delete=models.CASCADE,related_name='bet')``` -
Obtaining unique set of related models
I'm attempting to get a unique set of Employees that are represented within a queryset of jobs.

Thanks! -
Add view count if video is played more than 3 seconds
I am building a Simple Video App. What i am trying to do :- I am trying to add a user's view count if video is played more than three seconds. What i have done :- I got the video duration in miliseconds using pymediainfo. I made a view counter which is working fine(In video detail view) but. i don't know how can i get played duration of video. models.py class Video(models.Model): user = models.ForeignKey(User,on_delete=models.CASCADE,default='',null=True) video = models.FileField(upload_to='videos',null=True) viewers = models.ManyToManyField(settings.AUTH_USER_MODEL,related_name='viewed_video',blank=True,editable=True) views.py from pymediainfo import MediaInfo def videoListView(request,pk): videos = Video.objects.all() for vid in videos: media_info = MediaInfo.parse(f.video) duration_in_ms = media_info.tracks[0].duration queryset = Video.objects.annotate( num_views=Count('viewers')).order_by('-num_views') datas = get_object_or_404(queryset, pk=pk) if request.user.is_authenticated: created = Video.viewers.through.objects.get_or_create(video=datas, user=request.user) if created: datas.num_views += 0 context = {'vid':vid,'datas':datas,'duration_in_ms':duration_in_ms} return render(request, 'videoList.html', context) I have no idea how can i get video's played duration. Once i get the video's played duration then i will use if statement that if video_played_duration == 3seconds: then add view count. Any help would be much Appreciated. Thank You in Advance. -

Question in one of Cory Schafer's tutorials for Django
I am trying to learn Django by watching the Django course by Cory Schafer, and I'm just confused about the part where Cory used redirect after the registration process. if request.method == 'POST': form = UserRegisterForm(request.POST) if form.is_valid(): form.save() username = form.cleaned_data.get('username') messages.success(request, f'Account created for {username}!') return redirect('blog-home') else: form = UserRegisterForm() return render(request, 'users/register.html', {'form': form}) He used the return redirect('blog-home') and managed to show the message Account created for {username} in the template. But I'm not sure how he managed to access that message in the template without ever passing it similar with what we do with render method. Example of render method I learned is below, it's always passing the 3rd argument so that in the template we can manage to access it. But I have no idea how the message was passed via redirect method. return render(request, 'blog/home.html', context) -

Django: NOT NULL constraint failed: account_tutorvalidator.user_id

ManyToMany vs. Intermediary Model for Follower-Following Relationship for Django Rest Framework
I'm working on a blog application with Django Rest Framework (very original I know) and I'm trying to add a followers/following relationship between Users. Currently my UserProfile is implemented as follows: from django.db import models from django.contrib.auth import get_user_model from django.db.models.signals import post_save from django.dispatch import receiver User = get_user_model() class UserProfile(models.Model): """Model For Extending Default Django User Model""" user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='profile') username = models.CharField(max_length=150, blank=True, null=True) bio = models.TextField(blank=True, null=True) avatar = models.ImageField(blank=True, null=True) def __str__(self): return f'{self.user.first_name} {self.user.last_name}' @property def full_name(self): return f'{self.user.first_name} {self.user.last_name}' @property def posts_list(self): return self.user.posts.filter(author=self.user) @property def comments_list(self): return self.user.comments.filter(author=self.user) @receiver(post_save, sender=User) def create_profile(sender, instance, created, *args, **kwargs): """Automatically Create A User Profile When A New User IS Registered""" if created: user_profile = UserProfile(user=instance) setattr(user_profile, 'username', instance.username) user_profile.save() My goal is to create a way to link UserProfiles via a Follower/Following relationship. My first idea was to create a ManyToMany relationship like the following: followers = models.ManyToManyField('self', symmetrical=False, blank=True) This makes sense to me, since a UserProfile can have multiple followers and follow multiple people. If I want to serialize this model, then I can use something like the following: class UserProfileDetailsSerializer(serializers.ModelSerializer): posts_list = SerializerMethodField(source="get_posts_list") followers = SerializerMethodField(source="get_followers") class Meta: model = … -
Handling File Upload Errors in Django with DO/S3
I'm using django-storages with DO/S3 to upload a file from curl (later to be a Java client): curl -F some_file=@some_file.txt -F name=some_file --referer https://localhost:8000 -k -i https://localhost:8000/file/request Storage backend configured: storages.backends.s3boto3.S3Boto3Storage My model field: some_file = models.FileField('Some file', blank=True, null=True, upload_to=some_file_path) All this is working fine. I can send a POST request with a file and it uploads to the right place. What I'm trying to figure out is error handling. Since I'm relying on a third party CDN (DO) and library (boto3) to seamlessly upload files, how do I handle errors if the upload fails? I searched Django, DO, django-storages, and AWS docs and couldn't find a good answer. I'd like to handle failed uploads in a user friendly manner, but I'm not even sure how to test this scenario either. If I was calling this file upload in a view, handling the errors in a try block would be straight forward. But since this storage backend is only configured in settings to be the repository for all my uploaded files, how do I handle errors? Do I have to write a custom backend? Any help appreciated. -
Django - Would I be able to use template tags for rendering HTML given URL path conditionals?
I have a blog page with the path /articles/. I would like to use conditional statements to reflect HTML renders. For example, my blog uses a paginator for blog posts. The paginator uses a URL query to retrieve the next page of post objects like so: /articles/?page=2 I would like for the next page to stylize the HTML template differently, hence my reasoning for using a conditional statement. Here is my template that I use: {% if request.path == '/articles/' %} # Render HTML only meant for the above path {% elif request.path != '/articles/'%} # Render HTML for paths that are NOT the exact match above, such as pagination URLs, # search querys, categories filtering, etc... {% endif %} My current bug is that I'm only rendering the first statement: if request.path == '/articles/' for everything, even non exact matches. So this URL path: /articles/?page=2 is rendering: {% if request.path == '/articles/' %} when it should be rendering the elif {% elif request.path != '/articles/'%} due to the not equals sign. Is the above possible to do with only HTML template tags? I know I can use urls.py and edit views but I'm using wagtail CMS and playing with … -

Django simple app causes a circular import error, followed by a definition error
I'm having a seemingly simple definition error whereby the class Automation is not defined. I've created a very simple app called automations which seems to have caused a problem despite barely changing it.

Defining the initial values of a ModelForm in Django admin using the contents of the request
I'm trying to pre-fill a ModelForm for the admin interface of my Django application. I'm storing some values in request.session and I'd like to use them to define the initial parameter of my ModelForm. I'm able to retrieve these values in ModelAdmin.render_change_form(self, request, context, *args, **kwargs), but I'm not sure how to pass them to the form. Is it possible to do this? I guess I should use a class factory (taking inspiration from this answer) but I'm not sure where to call it, as ModelAdmin.form is a class attribute, not an instance attribute. Below is a short version of the code I'm using. ## admin.py @admin.register(Game) class GameAdmin(admin.ModelAdmin): # ... # This is where I'd like to pass the value of request.session["prefill_data"] form = GameAdminForm() # inherits forms.ModelForm() def render_change_form(self, request, context, *args, **kwargs): self.change_form_template = 'my_app/admin_game.html' extra_context = {} if "prefill_data" in request.session: # I'm able to access this data here extra_context["something_available_for_the_template"] = something_i_did_with prefill_data # Once I've done what I need I can safely delete the session variable del request.session["prefill_data"] return super(GameAdmin, self).render_change_form(request, context | extra_context, *args, **kwargs) # This is actually the view that populates request.session def admin_prefill(self, request): # [something something] request.session["prefill_data"] = foo # … -
Django Channels: Saving logged in user to session
According to the docs: If you are in a WebSocket consumer, or logging-in after the first response has been sent in a http consumer, the session is populated but will not be saved automatically - you must call scope["session"].save() after login in your consumer code: However, I am having some trouble implementing this. I start by getting my user: def login(form_data): try: user = User.objects.get(username=form_data['username']) except User.DoesNotExist: return "This account doesn't exist." password = form_data['password'] if check_password(password, user.password): return user else: return "Incorrect Password." And then following the directions like so: user = login(form_data) async_to_sync(login)(self.scope, user) self.scope["session"].save() self.send(text_data=to_json({ 'operation': 'set_user', 'success': True, 'message': "Loading User Data", 'object': {'username': user.username} })) And it works to deliver the user to the page and set it up for the life of the consumer. However, it seems that the user is not being saved to the user's session, because when I reload the page, self.scope['user'] once again returns an AnonymousUser object. This is how I've got my asgi.py set up: application = ProtocolTypeRouter({ "http": get_asgi_application(), "websocket": AuthMiddlewareStack( URLRouter( routing.websocket_urlpatterns ) ), }) Likewise, navigating to other pages confirms that I am indeed not logged in. What could I be missing? -
