How to prevent django admin login and logout sessions from reflecting in actual website?
I'm quite new to django. I've made a website that makes use of user auth for login, logout and registration. Whenever I log into the admin panel, it also gets reflected in the actual website. The admin account gets logged into the website on its own. I know this is the default behaviour of the django auth system, but I want to separate the auth session of admin panel and the actual website. How can I do so? The screenshots below show the thing which I'm talking about. 👇 Here I've logged into the Admin panel. 👇 The Admin account got logged into the website on its own by using the admin session.. I just want that both admin panel and website should have separate auth sessions and shouldn't be linked to each other. The website is hosted online here Thanks in advance! -

So for example, an update signal will be fired when status of A is changes. I would then want to change the status of B and C in this trigger. But as soon as the status of B changes, the post_Save signal will again be hit and the code would not even reach to … -
