Django - checklist : when seeding is not working (lambda)

[*this post will be updated as the time passes]

 

Problem.

Explanation.

'This means 'room_types' is None. So I can't call 'random.choice' on something that is None.'

 

How I solved?

1. Keep calm and log in to the admin panel http://127.0.0.1:8000/admin/

2. Then add a room types with any name.

3. the command should work as I desired.
