Re: test error

Hi Joel, 

The fact that you are using Django 2.2 has nothing to do with if f strings are supported. f-strings are a part of the python language. You need to have at least version 3.6 installed to be able to use f-strings. Check your python version by writing : python --version in a command shell. If it's less than 3.6 f strings don't work.

Also regarding how you are writing your tests, you don't need to use an f-string there at all - you can just test:

self.assertEqual(post.author, 'testuser1')

and so on.

Regards,

Andréas

Why did you say that? I'm using django 2.2 and f strings are indeed supported.

Sincerely yours,
