How to limit usage for freemium django app
I'am just struggling to figure out how can I limit my app usage for freemium users. Basically I want to make a variable on my model which I can set the usage limit for freemium usage, ex. allowing them 100 request per day. I found django ratelimit app. However I`am just wondering is there any other way to make this. -
Django REST Custom (token) authentication
Because I'm mixing things up and just making myself more confused, maybe someone can actually guide me through it. I need to make a Django REST API that requires login. However the User table already exists in a Postgres database. I think token-based authentication is most suitable, however, those tokens don't exist yet. (Login once to retrieve/create a token, check the token on each request) How can I use a POST request to submit login details purely for verifying the user? How would I generate a token upon successful login, and should I store it in a new Token table? After this, how can I use the token to provide authentication/authorization on API data requests? All examples I can find use the default Django User model or don't go into enough detail, which I can't use in this case. I've made a custom authenticator that checks the username and password, however I can't get through the next steps. from api.models import LogonAccount from rest_framework import authentication from rest_framework import exceptions import bcrypt class ExampleAuthentication(authentication.BaseAuthentication): def authenticate(self, request): username = request.data.get('username') # get the username request header password = request.data.get('password') # get the password request header if not username or not … -

Using mock objects to test Python/Django models
I'm building some Django models I'd like to test. I'm trying to avoid having to create lots of unnecessary objects purely to run unit tests. I thought unittest.mock might help with this but I'm really struggling to understand its operation. All the tutorial examples seem to relate to mocking external API calls which is a use case I think I understand but I'm beginning to think either it might not be applicable to my situation or I'm just misunderstanding it completely. This is a typical model: class Foo(models.Model): id = models.AutoField(primary_key=True) bar = models.ForeignKey(Bar, models.RESTRICT) ...other FKs baz = models.PositiveIntegerField() def do_something(self): return True if self.baz > 10 else False And my issue is I want to test do_something() but I don't want to create a full Foo object with objects for all those FKs. I was hoping I could do something like this, but clearly I've got something wrong along the way. @patch('models.foo.Foo') class FooTestCase(TestCase): def test_foo_do_something(self, foo): f = foo() f.baz = 20 self.assertTrue(f.do_something()) Can anyone show me where I'm going wrong? -

Django - return char-field for each object in model
Goal: I'm trying to allow for the saving of each players score when saving a game using the create view. So for each object that is returned for Person a char-field should be shown in the create view. Current: What's currently happening is all of the Person objects are showing up in a char-field and are able to be selected but there is no where to enter the score. How can I show a char-field for each Person object that is returned in my Game create view? (Note: I been through both of these questions & tried all the answers with no luck.

Avoiding InconsistentMigrationHistory with explicit inserts in migrations
I have a little problem with the order of the migrations. The fact is that in my database there is a "Products" model whose migration is one of the first in the history list, call it 001_products. After this migration, others are executed that make inserts in this same table (some inserts necessary for the basic operation of the application), called migration 002_inserts_products. The problem appeared when modifying the "Products" model, call it 003_modify_products migration. The migration was applied after the inserts and made the tests fail (tests that generate a test database doing all the migrations), which followed this order: 001_products 002_inserts_products 003_modify_products The solution then was to add a dependency on migrations that made inserts in "Products" with respect to the subsequent migration that modified that table. That is, make 002_inserts_products dependent on 003_modify_products. However, this, which worked in the tests and locally (where the modification in "Products" had already been applied), does not work in production, since there the migration that has not been applied is the one that modifies the "Products" model ". That is, the panorama in production is: [X] 001_products [X] 002_inserts_products [ ] 003_modify_products When trying to do the new migration, the error … -

DRF OPTIONS request - include initial/default choices
I'm using options to populate select inputs in my project. Is there a way to include also information about default values? For this field: DELIVERY_METHOD__SHIPPING_ONLY = 'shipping_only' DELIVERY_METHOD__LOCAL_PICKUP_ONLY = 'local_pickup_only' DELIVERY_METHOD__SHIPPING_AND_LOCAL_PICKUP = 'shipping_and_local_pickup' DELIVERY_METHOD_CHOICES = ( (DELIVERY_METHOD__SHIPPING_ONLY, 'Shipping only'), (DELIVERY_METHOD__LOCAL_PICKUP_ONLY, 'Local pickup only'), (DELIVERY_METHOD__SHIPPING_AND_LOCAL_PICKUP, 'Shipping & local pickup'), ) delivery_method = models.CharField(max_length=32, choices=DELIVERY_METHOD_CHOICES, default=DELIVERY_METHOD__SHIPPING_ONLY) The OPTIONS actions.POST.delivery_method is this: "delivery_method": { "type": "choice", "required": false, "read_only": false, "label": "Delivery method", "choices": [ { "value": "shipping_only", "display_name": "Shipping only" }, { "value": "local_pickup_only", "display_name": "Local pickup only" }, { "value": "shipping_and_local_pickup", "display_name": "Shipping & local pickup" } ] }, But it should also say that Shipping only is the default one so I can prepopulate the input with this value.

How to run a project in single docker container and run the installed dependencies of project in docker filesystem instead of using docker images?
I am new to docker I am noob and I have a full running application in docker consist of multiple containers responsible to run the project. I want to make the container image and gave it to the client but when I pushed my project to docker-hub it can only contain one container in the repository at a time. So, now I want to work with single container instead of using the multiple containers running MySQL and Redis as the dependencies of project. So, I installed redis and MySQL inside the docker file-system using bash of my container. But my project is not working without running my project I cannot start the redis and MySQL installed inside the container which is running on Debian Linux and when I run my project I can access the bash of my container and start the services but still my django app in the container is giving errors relevant to SQL. Can anyone tell me how to tackle this situation? -
Send Django-form to other server for data-handling
I have a Django app which is hosted on Google App Engine. One of the models consist of three fields class product_prices(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete = models.CASCADE,null=True) start_price = models.FloatField(default=0) last_price = models.FloatField(default=0) data = models.TextField(max_length=512) I want to do some database calls, based on the information entered, and then alter the data-field, the last-price based on the data returned from the database, e.g in my (pseudo) view below, I call MyDatabaseFunctionCall(form) to do those calculations. What I would prefer is, to have that calculation being on another server with some more CPU/RAM such that I don't slow down GAE hosting my application. #Current views.py on GAE def add_link_to_track(request): user = request.user instance = MyModel(user=user) if request.method == "POST": form = MyForm(request.POST,instance = instance) if form.is_valid(): #Create the dummy-model form.save() #Do the calculation in the back-ground thr = threading.Thread(target=MyDatabaseFunctionCall,args=(form,),daemon=True) #Alters the data thr.start() return redirect("my_site") else: form = MyForm() return render(request, "my_site/my_template.html",context=context) Can a form-instance e.g be pickled and thus send back-n-forth between servers in some way? Or is it better having a "temp-database" that I push the form information to uppon creation and then having the compute-server monitoring that database such that it can pull new forms, alter … -

Django REST framework POST without insert
I'm building a Django REST API which has access to our existing database with existing users. The purpose of this API is allowing the upcoming mobile application to make requests. I'm sending a post request to a view with custom authenticator to verify the sent account details. My existing model: class LogonAccount(models.Model): id = models.BigIntegerField(primary_key=True) email = models.TextField() two_step_enabled = models.BooleanField() password = models.TextField(blank=True, null=True) username = models.TextField(unique=True, blank=True, null=True) My View and Serializer class LogonAccountViewSet(viewsets.ModelViewSet): queryset = LogonAccount.objects.all().order_by('username') serializer_class = LogonAccountSerializer class LogonAccountSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = LogonAccount fields = ('username', 'email') Sending a post request to this endpoint with username and password in its body keeps returning me a bad request (400) with: { "username": [ "logon account with this username already exists." ], "email": [ "This field is required." ] } Making the fields not required in the serializer just changes the error to database constraints (null value in column id) class LogonAccountSerializer(serializers.HyperlinkedModelSerializer): username = serializers.CharField(required=False) email = serializers.CharField(required=False) class Meta: model = LogonAccount fields = ('username', 'email') I'm not trying to insert data, just trying to validate it.

Converting djangos object.values dict into native datatype?
