How do I use Django channels to open a Websocket for Django Rest Api?
https://github.com/prateekamana/tempstack So I have a simple app where I want to fetch articles in my react fronted without having to refresh the page dynamically. I know for that I either have to implement websockets or sse connection. So I tried to implement that using Django channels but I can't figure out how to set it up. I installed channels but everywhere the examples are for a chat application, I just want to simply fetch articles with the websocket from my rest api. Could you please tell me how do I route the websockets without the AuthMiddlewareStack() ? (Because I gather that has to do something with user authentication which I don't want to deal with as it is not a chat app.) # WebSocket chat handler "websocket": AuthMiddlewareStack( URLRouter([ url(r"^chat/admin/$", AdminChatConsumer), url(r"^chat/$", PublicChatConsumer), ]) ), # Using the third-party project frequensgi, which provides an APRS protocol "aprs": APRSNewsConsumer, })``` -

Django massmailer - TemplateDoesNotExist
I am trying to setup up the django massmailer app for use in my project. However, several templates seem to be missing.

CRUD operation within multi step form
I am not sure what is the exact name of what I am about to describe. Nevertheless, I am trying to replicate something like below picture. Where a client is able to add, delete and adjust as many users as he wants while seeing overview in the table below. I thought the best way to go about is to create a view of a form that is called when you 'Add new user'. Thereafter, you would have a view with the table below where you just loop through users to show information you want (User, Amount, Edit...). My question is how to go about it when I want to keep these created users separate from each client. In another words, if you and I both create users on the app, I do not want to show you users I created and vice versa. Is storing this in session a viable way or are there any better and more efficient approaches?enter image description here -

How to define a case insensitive Foreign Key relation in Django Models.py?
My models.py looks like this: class UserRoles(models.Model): userId=models.TextField(db_column='user_id',primary_key=True) loginId=models.TextField(db_column='login_id', unique=True) userRole=models.TextField(db_column='user_role') class Assets(models.Model): user = models.ForeignKey(UserRoles,db_column='User',to_field='loginId',on_delete=models.PROTECT) In my views.py, whenever I make an Object: object = Assets.objects.all(); The join between Assets and UserRoles is made automatically on the Foreign Key value. However, the field 'user' is in uppercase and 'loginId' is in lowercase. Thus, only the rows with numeric values in loginId are fetched. How can I change the relation between the Foreign Key to be case-insensitive? Something along the lines of select * from Assets inner join UserRoles on lower(Assets.user) = UserRoles.loginId; Note that I cannot make changes in the actual database itself (which is in Postgres if relevant). -

Django admin.py ValueError when trying to save manytomany field
I am trying to create a model with a manytomany field in Django, and using the default admin.py interface I am getting a ValueError: needs to have a value for field "id" before this many-to-many relationship can be used.

I'm trying to post data as well as map data between two fields in the database. My Model class Category(models.Model): name = models.CharField(max_length=40) class Expense(models.Model): category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name="category_name") description = models.CharField(max_length=200) total_amount = models.IntegerField() class Expense_Details(models.Model): expense = models.ForeignKey(Expense, on_delete=models.CASCADE, related_name="payment") user = models.IntegerField() amount = models.FloatField() type = models.CharField(max_length=100) ---->type is owe or lend I'm trying to post data in the database as well as map the amounts between users who lend money from whom so when I try to get money. My post request is in the following form. { “description”: “lunch at the burj al arab”, “category”: 1, “total_amount”: “105”, “owe”: [ { “user_id”: 1, “amount”: 10 }, { “user_id”: 2, “amount”: 95 } ], “lend”: [ { “user_id”: 3, “amount”: 10 }, { “user_id”: 4, “amount”: 95 } ] } I want to map one user with another such that the users with the same amount are people between whom transactions occurred. i.e user_id-> 1 own $10 which was lend by user_id -> 4 and I can query between them and find users settlements. I have made post request but I'm unable to map between users. How can I achieve this? -
