How to pass model fields to a signal receiver method?
I have a Founder(models.Model) with some fields like name=models.charfield; I want to execute post_save signal to a receiver function "generate" which will run a custom "management.call_command" function which takes "name" as an argument. To my understanding, this receiver "generate" function should be a method of a Founder for it to be able to take it's name field as an argument ? but when I'm creating a founder in admin, I get an error in console saying TypeError: generate() missing 1 required positional argument: 'self' -
Cross-project iframe testing on localhost with different ports
I am relatively new to iFrame, and what I try to do is to load project A in an iframe that is in project B. Project A is running as a Django project on localhost:8000, and project B as a separate Django project on localhost:8001. Inside the project B, I have a Django template with the following content: <iframe src="http://127.0.0.1:8001" height="500px" width="500px"></iframe> The problem is that instead of seeing the content of project A home page, I see error message stating that: 127.0.0.1 refused to connect Is there anything I am terribly missing? -

django-rest-framework csrf cookie not set react
I am new to Django, react and "http header" related stuff. My django dev server runs at: http://127.0.0.1:8000/ and my react dev server runs at: http://127.0.0.1:3000 In order to access the website, login is required. So, all unauthorized requests are 1st redirected to login page, by configuring react-router and following this template. So, till now, no api calls are made. In order to post login data, i need to have csrf token set by the server. But since i have not made any api calls, i created an endpoint /api/csrf/ explicitly, to set the csrf token. # URL: /api/csrf/ class CSRFGet(APIView): """ Explicitly set csrf cookie """ @method_decorator(ensure_csrf_cookie) def get(self, request): return Response('hello') I call this endpoint, when useProvideAuth hook is mounted. function useProvideAuth() { const [token, setToken] = useState(null); const login = (username, password) => { return axios.post( '/auth/', { username: username, password: password }) .then(response => { setToken(response.token) }) } useEffect(()=> { axios.get( '/csrf/' ) },[]) return { token, login, } } To retrieve and set this cookie, i followed the official Django docs.

How to Group by timestamp column serving as PK by day/month/year, and select that timestamp column at the same time in Django
I have a table with a 'timestamp' field as its PK. In Django View, I want to select all from the table and group by month('timestamp) and year('timestamp). In terms of MySQL script, I am looking for this: SELECT timestamp, sum(col1) col1, sum(col2) col2 FROM my_table GROUP BY MONTH(timestamp), YEAR(timestamp) ORDER BY timestamp One approach I have followed is from here. You can find more elaboration on that answer here. So to GROUP BY the rows, I work with annotate and values as discussed in this answer. The code in my Django View is the following: from django.db.models.functions import TruncMonth, TruncYear from django.db.models import Sum queryset = MyModel.objects .annotate(month=TruncMonth('timestamp'), year=TruncYear('timestamp')) .values('month', 'year') #Group by Month and Year .annotate(col1 = sum('col1'), col2 = sum('col2')) #Sum data of two columns .order_by('month', 'year') #Also tried 'timestamp' here. queryset_serialized = MySerializer(queryset, many=True) The code above does produce the query as expected. Here is the query generated from the code above: SELECT CAST(DATE_FORMAT(`timestamp`, '%Y-%m-01 00:00:00') AS DATETIME) AS `month`, CAST(DATE_FORMAT(`timestamp`, '%Y-01-01 00:00:00') AS DATETIME) AS `year`, SUM(`col1`) AS `col1`, SUM(`col2`) AS `col2` FROM `my_table` GROUP BY CAST(DATE_FORMAT(`timestamp`, '%Y-%m-01 00:00:00') AS DATETIME), CAST(DATE_FORMAT(`timestamp`, '%Y-01-01 00:00:00') AS DATETIME) ORDER BY `month` ASC However, while serializing the data … -

One transaction for mongoDB and MySQL with one to many relationship
My Django application uses both MySQL and MongoDB to store its data. I need to create one transaction to delete an instance with its relations from both MySQL and MongoDB. If the execution of one of the queries fails (SQL or Mongo) I must rollback all the executed queries. Is that possible? Example: from django.db import models class Car(models.Model): manufacturer = models.ForeignKey('Manufacturer',on_delete=models.CASCADE) # ... def delete(self, *args, **kwargs): ... # delete from mongoDB (must use a session to support multi document tr return super(Instance, self).delete(*args, **kwargs) class Motorcycle(models.Model): manufacturer = models.ForeignKey('Manufacturer',on_delete=models.CASCADE) # ... def delete(self, *args, **kwargs): ... # delete from mongoDB (must use a session to support multi document tr return super(Instance, self).delete(*args, **kwargs) class Manufacturer(models.Model): # ... pass def delete(self, *args, **kwargs): ... # delete from mongoDB (must use a session to support multi document transaction) return super(Instance, self).delete(*args, **kwargs) When I delete a manufacturer, I need to delete the related cars and motorcycles from both MySQL and MongoDB. If one transaction fails (let's say delete one of the motorcycles has failed for some reason), I need to rollback all the transactions. Is there any way to do it? -
preferred way of designing model in Django
I have a very simple model in Django with 3 fields. The issue is that I have dozens of billions of data that needs to be stored in the table associated with that model in Postgresql database. I stored around 100 millions of rows, and then my server first got sluggish and then gave me "Nginx 505 bad gateway" when clicking on that table in Django admin or requesting data using API. I was wondering what is the best way to handle this simple scenario of having massive data in Django. What's the best model. Should I split my model in order to split my table? Thanks, -
Why does ChannelsLiveServerTestCase doesn't allow file upload
I am currently using ChannelsLiveServerTestCase to spin-up a runserver for my test, for some reason when I try to test my file upload feature it is failing but when I try using different "test server" (StaticLiveServerTestCase) it is working well. I opted to use ChannelsLiveServerTestCase because I need the websocket support which is not possible with StaticLiveServerTestCase.
