I was following a tutorial and accordingly I created a app name accounts with this I was proceeding , later I found that name should be ‘accounts’ then I directly renamed it and again I was getting some errors then I deleted that app and created with same name ‘accounts’ from that very moment I am getting these:

I don’t see a difference between the two names you posted - they both look like accounts to me.

Anyway, deleting apps is one of the most fault-prone operations you can perform with an existing database. If someone wants to delete an app, my general recommendation is that you drop and recreate the database as well. Then do your makemigrations, and then migrate to initialize that fresh database without any leftovers from the deleted app.

You might also want to scan your entire source code for any references to that app in your settings, urls, models, views, or templates; or possible imports or foreign key references that might specify the original app.
