When I use axios in vue to send a request, django can get the request, but it cannot return the value in request.session. The return value of axios is always null.

What is the best approach to handle long tasks in a django app
So I have one function where clients uploads files and does a little parsing and then proceeds to send these results using another API. Now each file takes around 30 seconds to complete and a large deal of that is a POST request im making and awaiting an answer for 25 seconds. My initial solution was that when a client sent a request about this particular function of my app I'd just loop through all those files until the task was completed and then sent back a http response. Of course I noticed that I started getting 504 error because it was taking too long. My second, and current, solution is to respond with a http response immediately containing an empty html page where I then use javascript to use fetch to make calls to this function(a django view) and continually update the page and tell the client that a file has been processed. I also introduced threads to this solution and to my surprise it made it a lot faster, I suppose that is because each thread can get to that point where it waits for the long POST request so going from one to two almost doubled the … -

Writing your first Django app, part 5 error import models

simplejwt token work for all tenants for django-tenants
I just want to mention about my problem. I have already researched many documents but I could not find any solution. I just try to use django-tenants. Everything seems OK. But If any user gets the token after login, that token works for all tenants. It's a big leak of security. I have been thinking about an idea SIGNING_KEY. If I can change SIGNING_KEY for each tenant, it may be fixed. But It did not. class TenantJWTAuthenticationMiddleware(MiddlewareMixin): def process_request(self, request): tenant = Client.objects.get(schema_name=connection.schema_name) jwt_secret_key = tenant.jwt_secret_key settings.SIMPLE_JWT['SIGNING_KEY'] = jwt_secret_key This is my Middleware to change SIGNING_KEY for each tenant. class Client(TenantMixin): name = models.CharField(max_length=100) paid_until = models.DateField() on_trial = models.BooleanField() created_on = models.DateField(auto_now_add=True) jwt_secret_key = models.CharField(max_length=100, null=True, blank=True) # default true, schema will be automatically created and synced when it is saved auto_create_schema = True class Domain(DomainMixin): pass This is my model. So, I added jwt_secret_key into my model and I got this field in Middleware and tried to set SIGNING_KEY for jwt. But still, jwt after user login can be used for all tenants. Does anyone have any idea about my problem? Any suggestion or amendment to my solution? Thanks. -
how to refresh the page without reloading, using django, ajax, jquerry?
So I am trying to delete products from cart without refreshing the entire page, I can delete an item and then I need to reload the page to delete another item.

django orm filter doesn't find the result but I know the result exists
I have a mySql database in server and it has about 5000 rows of data in one table. my model is like this: class Names(models.Model): title = models.CharField(max_length=100) descriptions = models.CharField(max_length=500) is_approved = models.BooleanField(default=False) count_stars = models.FloatField(default=0.0) count_visited = models.FloatField(default=0.0) count_shared = models.FloatField(default=0.0) gender = models.ForeignKey(Genders, on_delete=models.CASCADE) root = models.ForeignKey(Roots, on_delete=models.CASCADE) def __str__(self) -> str: return self.title my mission is to find a specific row in the database by the field of 'title', when the title is in the first tens of rows in the database, everything works good but when the title is in the deeper rows, it can not find it. my view function is: @api_view(["Get"]) def get_name_by_name(request, keyName): value = models.Names.objects.filter(title=keyName).first() serializedValue = serializers.nameSerializer(value) result = serializedValue.data return Response(result) database rows: 1- found 2- found . . n- not found . . 5000. not found what is the problem? I searched about async programming but it didn't work
