Django Form says image field is required meanwhile image is uploaded in Graphql Altair client
I'm using GraphQL in a Django project and the Altair GraphQL client, and I'm facing an issue with file uploads. When the request is submitted via Altair, the submitted fields are detected in my ImageUploadMutation. After initialising the form with the fields (form = ArtistPhotoForm({'photo': file})), form.data also prints the right fields. However, after calling the form.is_valid() method, I get photo: This field is required! Here are the important code segments: models.py class ArtistPhoto(models.Model): # Use width_field and height_field to optimize getting photo's width and height # This ThumnailerImageField is from easy_thumbnails; but i don't think the issue is here photo = ThumbnailerImageField( thumbnail_storage=FILE_STORAGE_CLASS(), upload_to=ARTISTS_PHOTOS_UPLOAD_DIR, resize_source=dict(size=(1800, 1800), sharpen=True), validators=[FileExtensionValidator(['png, jpg, gif'])], width_field='photo_width', height_field='photo_height' ) photo_width = models.PositiveIntegerField() photo_height = models.PositiveIntegerField() forms.py class ArtistPhotoForm(forms.ModelForm): class Meta: model = ArtistPhoto fields = ['photo'] mutation # Output class contains the fields success and errors class ImageUploadMutation(graphene.Mutation, Output): class Arguments: file = Upload(required=True) form_for = ImageFormEnum(required=True) # Apparently this should be an instance method not a class method @verification_and_login_required def mutate(self, info, file: InMemoryUploadedFile, form_for, **kwargs): if form_for == 'artist_photo': form = ArtistPhotoForm({'photo': file}) if form.is_valid(): print("Form is valid") print(form.cleaned_data) return ImageUploadMutation(success=True) print(form.errors) return ImageUploadMutation(success=False, errors=form.errors.get_json_data()) I get the error message { "data": { … -

Best way to create a queue for handling request to REST Api created via Django
I have the following scenario: Back end => a geospatial database and the Open Data Cube tool API => Users can define parameters (xmin,xmax,ymin,ymax) to make GET requests Process => On each requests analytics are calculated and satellite images pixels' values are given back to the user My question is the following: As the process is quite heavy (it can reserve many GB of RAM) how it is possible to handle multiple requests at the same time? Is there any queue that I can save the requests and serve each one sequently? Language/frameworks => Python 3.8 and Django Thanks in advance -

Trying to add new model and field to existing data in Django
I'm learning Django and making a kind of social network and am trying to add a model and field to my models. The following post perfectly explains what I'm trying to do... Django - Private messaging conversation view I'm trying to add the model and field after I already have some messages saved. I'm making this for learning purposes for now, so deleting the existing messages and starting over would probably solve the problem, but I'm trying to learn how to navigate this because next time I could have actual users and deleting the messages might not be possible.

Creating a function to auto-populate field with another model's field
I want to auto-populate item_selected field from my Order model with the items of the Order (which also a field from Order model). Its difficult for me because they represent different things but similar. Please follow me I will explain better below: From the image above. What I want is to have item selected populate by whatever is selected in items, so in this case, I want "titletitle2" be chosen in item selected since it is selected in Items. So no matter how many times "titletitle2" is selected in items it will just be chosen in item selected once. I assume this can be achieved in the Models, this is the Estore Model below: class eOrderItem(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) ordered = models.BooleanField(default=False) item = models.ForeignKey('blog.Post', on_delete=models.CASCADE) item_variations = models.ManyToManyField( ItemVariation) quantity = models.IntegerField(default=1) def __str__(self): return f"{self.quantity} of {self.item.title}" def get_total_item_price(self): return self.quantity * self.item.price def get_total_discount_item_price(self): return self.quantity * self.item.discount_price def get_amount_saved(self): return self.get_total_item_price() - self.get_total_discount_item_price() def get_final_price(self): if self.item.discount_price: return self.get_total_discount_item_price() return self.get_total_item_price() class Order(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) ref_code = models.CharField(max_length=20, blank=True, null=True) items = models.ManyToManyField(eOrderItem) item_selected = models.ManyToManyField( 'blog.Post', blank=True) start_date = models.DateTimeField(auto_now_add=True) ordered_date = models.DateTimeField() ordered = models.BooleanField(default=False) shipping_address = models.ForeignKey( 'Address', related_name='shipping_address', on_delete=models.SET_NULL, … -

Real time updates from Rest API
I created the REST API in Django and android application in Java. I need to send/receive real-time updates from the API I developed. May anyone tell me the possible solution to achieve this, Django channels or polling data periodically or other alternatives.

Django REST to_representation: Have serializer fields appear last
I have the following serializer class: class DataLocationSerializer(QueryFieldsMixin, serializers.ModelSerializer): def create(self, validated_data): pass def update(self, instance, validated_data): pass class Meta: model = MeasurementsBasic fields = ['temp', 'hum', 'pres', 'co', 'no2', 'o3', 'so2'] def to_representation(self, instance): representation = super().to_representation(instance) representation['timestamp'] = instance.time_received return representation The data is returned in a JSON file structured like this: { "source": "ST", "stations": [ { "station": "ST1", "data": [ { "temp": -1.0, "hum": -1.0, "pres": -1.0, "co": -1.0, "no2": -1.0, "o3": -1.0, "so2": null, "timestamp": "2021-07-04T21:00:03" } ] } ] } How can i make it so the timestamp appears before the serializer's fields? -

How to pass additional arguments to class view in django?
def edit_course(request,course_id): course=Courses.objects.get(id=course_id) return render(request,"hod_template/edit_course_template.html",{"course":course,"id":course_id}) The code above shows a view in django that is defined as a function. I want to recreate the same view as a class based view in django but I couldn't pass in an additional argument such as course_id into the class based view as it shows an error. Can someone tell me how to recreate that above function into a class based view ? -
