Using postman formdata it is saying, that category field is required despite I filled it. -

Get User ID from rest-auth social Login
I have been trying extensively to get the User ID from Django rest-auth Google login. The default response is: { "key": "6ee5ff4db218a25113f35580d00aeeaf2fe8a2d1" } which is not enough, I need to have the user ID with it. I looked at using custom model serializers but to no avail. My class-based view is: class GoogleLogin(SocialLoginView): adapter_class = GoogleOAuth2Adapter Would appreciate any guidance in this regard. Thank you -
Detect if a model is the through model of an M2M relationship
I've got a widget which offers choices built from content types so that objects can be referenced by ID & content type. I'd like to exclude from those choices; proxy models, automatically created models and M2M (through) models. While inspecting the model _meta I found many_to_many so have implemented the following; content_types = ContentType.objects.all() cts = {} for ct in content_types: model = ct.model_class() _meta = getattr(model, '_meta') if not _meta.proxy and not _meta.auto_created and not _meta.many_to_many: cts[ct.id] = str(_meta.verbose_name) This dictionary is then fed to javascript and a select box is generated. The problem that I have, is that models are being excluded simply for containing a ManyToManyField. What's the correct way to identify a through model if not many_to_many? -

Saving foreign key from form
I have an Order model and an Address model. Address is a foreign key on an Order.

How to filter a django OR query correctly
I tried to make an OR query with django q.

How to get a django field value throw a custom models.Field?

How to Check box filter In Django?
I'm using Django as backend, Postgres SQL as DB, and HTML, CSS, and Javascript as frontend. I am stuck in the filtering option, where the user selects check one brand and shows the selected brand list in the template. So basically like this: I have multiple specifications for each category. Like Mobiles have: Brand RAM ROM etc. Till now, I have done list filtering but I want check-box filtering. The Codes goes here: views.py def product(request, data=None): product = Product.objects.all() if data == None: proc = Product.objects.filter(category = 1) elif data == 'OnePlus' or data == 'boAt' or data == 'Redmi' or data == 'realme': proc = Product.objects.filter(category = 1).filter(brand = data) return render(request, 'list/processor.html', {'product': product, 'proc':proc,}) product.html <ul class="list-group"> <a style="text-decoration:none" href="{% url 'main:product' %}"> <li class="list-group-item d-flex justify-content-between align-items-center"> All </li> </a> <a style="text-decoration:none" href="{% url 'main:productdata' 'OnePlus'%}"> <li class="list-group-item d-flex justify-content-between align-items-center"> OnePlus </li> ....... </ul> I have searched for Django-Filter but proper implementation of check-box filtering not there.

Optimizing django rest framework API
I have created an API to get all the data from by database. There is a "deployment" table and a related table "sensors" which has a foreign key referencing the deployment, a one-many relationship. The serializer creates a nested JSON. Currently if I request all records it takes roughly 45 seconds to return the data (17,000 JSON lines). How do I profile my Django application to determine what is the bottleneck? Any suggestions on what can be improved to speed this up? Or is this is as good as it's going to get? models.py class deployment(models.Model): ADD_DATE = models.DateTimeField() #creation of record in db #...30 more fields.... class sensor(models.Model): DEPLOYMENT = models.ForeignKey(deployment, related_name='sensors', on_delete=models.CASCADE) ADD_DATE = models.DateTimeField() #creation of record in db SENSOR = models.ForeignKey(sensor_types, to_field="VALUE", max_length=50, on_delete=models.PROTECT) #...5 more foreign key fields... views.py class GetCrtMetadata(generics.ListAPIView): #Read only serializer_class = CurrentDeploymentSerializer queryset=deployment.objects.all().prefetch_related("sensors") filter_backends = [DjangoFilterBackend] filter_fields = [field.name for field in deployment._meta.fields] deployment app serializers.py class CurrentDeploymentSerializer(serializers.ModelSerializer): #Returns deployment with sensors sensors = SensorSerializer(many=True) class Meta: model = deployment fields = [field.name for field in deployment._meta.fields] fields.extend(['sensors']) read_only_fields = fields sensor app serializers.py class SensorSerializer(serializers.ModelSerializer): class Meta: model = sensor fields = [field.name for field in sensor._meta.fields] -

Django slow loading page due to lots of codes
I am implememting a small recommendation feature on my home page which will suggest jobs to candidates. To accomplish the latter, I have used CountVectorizer and Cosine Similarity. However, to perform this, I had to concatenate lots of fields from the candidate's profile and job description. This code is defined in the views.py. Every time I load the home page, this view gets executed and eventually, it takes time to load. Is there something I can do to improve the loading speed? Thank you guys ;)
