Django serializers usage with data transfer objects
I am from Java background and I am getting a bit confused with the serialization in Django Let's say I have this requirement I need to fetch the results of stocks from an exchange. So the request will be like { "exchange" : ["exchange1", "exchange2"], "stock_name" : ["stock1", "stock2"] } In Spring I would write a RequestDto like this, class StockResultRequestDto{ List<String> exchange; List<String> stockName; } and In the controller method getMethod(@RequestBody StockResultRequestDto request) and Jackson library behind the scenes would take care of the serialization. In Django Rest as well, I was thinking to have it similar @dataclass class StockResultRequestDto: exchange: List[str] stock_name: List[str] But since we don't have a builtin serializer in python, I understand, I will need to write serializer as well. class StockMarketRequestSerializer(serializers.Serializer): exchange = serializers.CharField(max_length=100, many=True) stock_name = serializers.CharField(max_length=200, many=True) @api_view(['POST']) def get_stock_result(request): serializer = StockMarketRequestSerializer(data=request.data, many=True) serializer.is_valid(raiseException=False) stockMarketDto = StockResultRequestDto(**serializer.validated_data) <--- Is it advised to create a dto when I can pass around serializer.validated_data? Coming to output considering I don't have a database involved, I fetch the results from a different server class StockResult: stockName: str netProfit: float revenue: float I do business logic and finally, I will have something like stock_result_response = [list … -

How to fix Django "ModuleNotFoundError: No module named 'application'" on AWS?
I am trying to redeploy a Django web application on AWS. My elastic beanstalk environment has been red a couple of times. When I ran eb logs on the cli, I am getting a "ModuleNotFoundError: No module named 'application' error". I think this has got to do with my wsgi configuration. I have deployed this web app on AWS before. I messed up when I tried deploying a new version then decided to just start over. Here is my wsgi.py configuration: ```import os from django.core.wsgi import get_wsgi_application from django.contrib.staticfiles.handlers import StaticFilesHandler os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings") application = StaticFilesHandler(get_wsgi_application())``` When I deploy the app, it's giving me a 502: Bad gateway error.

How can I prefetch nested tables?
I'm working on an app with a DRF API. Development has been going on for some months, but only now are we running into performance issues when populating the database with actual data. I have done some profiling and found out that many endpoints query the database hundreds of times to fetch the necessary data. This is something that can be solved with select_related and prefetch_related, that much I know, but I'm having a hard time picturing it. Models class LegalFile(models.Model): code = models.CharField(max_length=75) description = models.CharField(max_length=255) contactrole = models.ManyToManyField(LegalFileContactRole, blank=True, related_name='contactroles') class LegalFileContactRole(models.Model): contact = models.ForeignKey(Contact, on_delete=models.DO_NOTHING, blank=True, related_name='legal_file_contact') subtype = models.ForeignKey(ContactSubType, on_delete=models.DO_NOTHING, related_name='legal_file_contact_role', null=True) class Contact(models.Model): name = models.CharField(max_length=150) surname_1 = models.CharField(max_length=50,blank=True, null=True) surname_2 = models.CharField(max_length=50,blank=True, null=True) class ContactSubType(models.Model): pass Say I want to list all the LegalFiles in the database, and fetch the names and both surnames of the contacts associated to each LegalFile through LegalFileContactRole. Is there a DRYer way than using lowercase notation to prefetch like LegalFile.prefetch_related('contactrole__contact__name', 'contactrole__contact__surname_1', 'contactrole__contact__surname_2')? This kind of nested relationship is a recurring thing in the app. -

Correct way to handle .wasm.gz and .data files in Django?
I'm currently dealing with a problem in my django web application that is running locally on 192.168.0.168. I'm making use of an OCR library that makes use of .wasm.gz files and .data files. In the documentation they mention: " In some cases you need to configure your webserver to serve data and wasm.gz files.". My first idea was to add the following mimetypes in django: mimetypes.add_type("application/x-gzip", ".wasm.gz", True) mimetypes.add_type("application/octet-stream", ".data", True) I'm however still seeing the error: error wasm-instantie. It somehow can't instantiate wasm because django needs to serve the wasm.gz and .data files correctly. These have been added however to the static folder and I'm able to download them if I manually browse to the link. Does anyone have any idea what I need to do to serve these correctly? -
