Is this way of using assertRaises overkill?
I have the following method : def create_user(self, email, password, last_name, first_name): # (...) where all four parameters are mandatory. When testing this method, should I check with assertRaises whether a TypeError is thrown when one of the parameters is missing ? It would be pretty tedious to do have to write this : #(...) with self.assertRaises(TypeError): User.objects.create_user() User.objects.create_user(email='') User.objects.create_user(password='') User.objects.create_user(first_name='') User.objects.create_user(last_name='') User.objects.create_user(email='', password='') User.objects.create_user(email='', first_name='') User.objects.create_user(email='', last_name='') User.objects.create_user(first_name='', last_name='') User.objects.create_user(first_name='', password='') User.objects.create_user(last_name='', password='') User.objects.create_user(email='', first_name='', last_name='') User.objects.create_user(email='', first_name='', password='') User.objects.create_user(email='', last_name='', password='') User.objects.create_user(first_name='', last_name='', password='') What is the method had more mandatory parameters ? -
Not getting cookie in Django

How can I use Celery in Django with just the DB?
Looking at https://docs.celeryq.dev/en/v5.2.7/getting-started/backends-and-brokers/index.html it sounds pretty much as if it's not possible / desirable. There is a section about SQLAlchemy, but Django does not use SQLAlchemy. In way older docs, there is https://docs.celeryq.dev/en/3.1/getting-started/brokers/django.html . Is it possible with recent Celery / Django versions to use Celery with just the database for storing messages / results? -

django rest framework override save() method
When I override the save() method, the create() method is called inside, but when I add a read-only field uuid, the field is not serialized. serializer.py class AwsUploadFileSerializer(serializers.ModelSerializer): extract_file_name = serializers.CharField(source='extract_file.name', read_only=True) class Meta: model = ExtractAWSFile fields = [ 'uuid', 'extract_file', 'extract_file_name' ] extra_kwargs = { 'extract_file': {'write_only': True} } def save(self, **kwargs): instance: ExtractAWSFile = super().create(self.validated_data) res = upload_file_to_aws(instance.extract_file.path) if not res: instance.extract_file.delete() instance.delete() return instance response { "extract_file_name": "tets3.jpg" } So I'm trying to call the save() method of the parent class so that the uuid field can be serialized, but there is something wrong with the file name field I wrote earlier and it will take the path with it instead of just displaying the name. serializer.py class AwsUploadFileSerializer(serializers.ModelSerializer): extract_file_name = serializers.CharField(source='extract_file.name', read_only=True) class Meta: model = ExtractAWSFile fields = [ 'uuid', 'extract_file', 'extract_file_name' ] extra_kwargs = { 'extract_file': {'write_only': True} } def save(self, **kwargs): instance = super().save(**kwargs) res = upload_file_to_aws(instance.extract_file.path) if not res: instance.extract_file.delete() instance.delete() return instance response { "uuid": "c4aea74e-3748-4c05-8d6c-2413b1eebcc6", "extract_file_name": "extractAWS/2022/10/08/tets3.jpg" } Why is that?

How to perform eth contract transaction in Django using web3.py and Metamask
Trying to build a Dapp using Django, till now completed below steps. Deployed a simple lottery contract on test net, contract address is 0xD5d56C139848A0E55DC5C616D04a0CeD98D8BeA3 (can be seen at https://sepolia.etherscan.io/) Using web3.py I can connect to this contract and call the functions. I have created a simple webapp which ask user to connect to its Metamask wallet. I am using JS to load the Metamask wallet in the browser. When user click on connect wallet Metamask extension loads in the browser. Once user gets connected I can read the address of the connected user address. Next step is user will click on enter lottery button, after that Metamask should popup to sign the transaction. The Problem is I want to use the web3.py in my Django view to call my contract function which will allow user to enter in to the lottery game, but how can I call Metamask from Django view to ask user to sign transaction as it is browser extension. -
