How would I structure a single page application that takes an input, fetches data from the back end, then renders it to the front end with routers?
Example: https://redditmetis.com/ Issue I've been having trouble trying to structure a recent SPA I started. Like the above example, I need to accept an input, make a few API calls in the back-end, manipulate the data then render it the front-end. I'm currently going for a Django + React stack, since I'm pretty familiar with them. I can't really imagine how this would look like from a surface view, I've worked with API's before but I can't wrap my head around how the client and the server would interact with each other to make it all connect. What I have so far After looking into it, I think I need React Routers, similar to the example website provided. In my Django server, I plan on making separate API calls and running an algorithm to organize and sift through the received response, then pushing the product to the client. I'm still figuring out how to set that up, since most API calls are made on componentdidmount which only executes at the start of the DOM. This isn't much, but its a start. If anyone has pointers on how to start, I'd appreciate it, thanks. -
how to get complaint details of all the users in django except the user logged in
I am creating a system where users can log in and enter complaints, view and edit them as well and also view complaints of other users on a different page. I have already created a page where they can view their own complaints but i don't know how to let them view other users complaints. Can someone please tell me what to type into the views.py and the template? Do i also need to make a new form for this?

Navigating to different page instead of Ajax call
I am trying to save a form via ajax as I don't want to reload the page.

Django - How to give one object multiple relational objects and how to create them?

Django Login Form Displaying Incorrectly
My basic login page works fine when I go through the login link directly. It correctly applies the class 'form-control' to the input. The strange issue arrives if I try to visit a page that I need to be logged in for to view, it will redirect to the login page(as expected) but then for some reason it decides to not apply my attributes to the form. I am unsure as to why this is happening, maybe due to the redirect to the page instead of an actual visitation. I've attached screen shots to show exactly what I mean. When inspecting the html I can clearly see the attributes are not applying when it seems to be a redirect to the login page. Why does it behave in this way? What would be the best way to fix this? Any help is greatly appreciated! basic view for the login page class MyAuthenticationForm(AuthenticationForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['username'].widget = forms.widgets.TextInput(attrs={ 'class': 'form-control' }) self.fields['password'].widget = forms.widgets.PasswordInput(attrs={ 'class': 'form-control' }) -

JWT token authentication and autologin with ReactJS SPA and Django dj-rest-auth
I'm working on authentication system for ReactJS single page application and with backend in Django using dj-rest-auth package. The plan was to use JWT token for authentication, but there is one thing that causes my concern, which is CRSF protection. Normally, a user logs in in React, meaning provides email/username + password and the request to /login endpoint and dj-rest-auth LoginView urlpatterns = [ ... path('api/login', LoginView.as_view()), # dj-rest-auth view ... ] LoginView of dj-rest-auth package, when configured to use JWT tokens and disabled Session authentication as default (just JWT) automatically sets response cookies with jwt cookie and jwt refresh cookie (using Set-Cookie): set_jwt_cookies(response, self.access_token, self.refresh_token) which results in setting Secure and httpOnly cookies saved in my browser cookies like that (names of cookies are predefined by me in Django settings): Now - I'm expecting site to work in a way, that even after user closes the page and reopens it, my autologin feature in React would verify, whether user is logged in (or in other words authenticated to view protected page) - so if the user is authenticated - React will redirect to dashboard or some main authenticated page. Autologin feature basically sends request to endpoint /autologin using axios … -

Django - OperationalError after deleting migration files
In the earliest days of my system, before i knew how to utilize django's built-in User model, i had my own class named myUser which i intended to use for the same purpose. i ended up deleting this one and instead using django's User model. all was fine for a while. then i tried to change the id of all my custom models to a UUIDField, and got the syntax wrong, which i unfortunately only realized after i ran makemigrations and migrate. i corrected it, but there was still a bug because the migration file of the wrongly-syntaxed UUIDField still lingered in migrations. that's what i understood from googling for a while, anyway. since i wasn't sure which migration file caused the error, i just deleted the last 5 migration files (in hindsight, not the best idea i've ever had). Unfortunately, one of those migration files were the one which covered the deletion of the myUser model. now, whenever i try to migrate, i get the following error: django.db.utils.OperationalError: no such table: phoneBook_myUser it seems this error is stopping any of my new migrations to go through. i've googled for a while, and it seems my two options are to … -
