Integration of third party authentication on Django Project
I have an authentication system that is built in PHP for my clients to log in using only one login credential to access different products. Mostly my web pages are written in PHP so it is easy to integrate different PHP products with the same authentication. Now I have a Django webpage and want to authenticate my clients with the same authentication system that is written in PHP, is it possible? I have three PHP files which help me with the authentication can I directly tell my Django to use these files for authentication and after success redirect to the webpage to use different features inside the webpage? -
Simultaneously logins from multiple users without using framework in django
We are working on a django project and we want to allow users to be able to access the system simultaneously. However, we are having a problem in scenarios when for example: User1 logs in then User2 logs in next, if User1 did not logout from the system, when User2 refreshes the site, User2 is able to access User1 session. How can we prevent this from happening? Without implementing an API framework. Thank you. We tried to delete the request.session when the user logs out. -

JQuery / AJAX - Async view - eventlisteners not responding and .remove() is not respecting the selection
it is my first time writing JQuery/AJAX and (silly me) I'm tryng to do something quite complex actually (or at least it is for me lol). Basically I am making an infinte carousel.

Mass updating (including removal) of a many-to-many relationship django
I have a Django app with two models linked by a many-to-many relationship. Service, problem_type. A service provides assistance for a number of problem types. I use the problem_type table to later facilitate lookups of all services that help for a specific problem type. I update my model from an external API. I take in a list of "problem_types" for each service, eg: ['housing', 'financial aid' ... etc] Over time, a service might get new problem_types or remove old ones. Is there a best practice for managing this? Adding new problem_types relationships or new problem_types is ok, I just loop through the incoming list of problem types and add any new ones to the problem_type relationship/table, but what is the best way to remove now redundant ones? Is it best to: Loop through associated problem types and delete each not in the new incoming list? Get all associated problem types and delete every relationship before re-adding the incoming list Is there some built-in method for doing this that I have not been able to find? In an ideal world love to be able to pass the incoming list of new problem_types with the current set of related problem_types to a … -
