Re: Multiple Apps in one project with one database

2019-12-11 Thread Bruckner de Villiers 
OK, got it.  Changed polls2/views.py to “from polls.models import Choice, 
Question” instead of “from .models import Choice, Question”.  It works, but 
VSCode doesn’t like “polls.model” – it gives a warning “unresolved import”.

Much obliged,

Subject: Re: Multiple Apps in one project with one database

 

Multiple Apps can point to one database.

 

What happens is that django creates different tables in the database.

 

It uses this format to create the tables

 

'appname_modelname'

 

e.g.  polls_question

 

 

Infact, if you  remember earlier on before runnung your first "python manage.py 
migrate".  Django told you that you had "unapplied migrations"

 

When you applied the migrations you might have noticed some other tables were 
created in the database. Tables like auth, session, admin, etc

Migrations for 'polls2':

  polls2/migrations/0001_initial.py

- Create model Question

- Create model Choice

(pyfun) Bruckners-MacBook-Pro:mysite brucknerdevilliers$ python manage.py 
migrate

Operations to perform:

  Apply all migrations: admin, auth, contenttypes, polls, polls2, sessions

Running migrations:

  Applying polls2.0001_initial... OK

So, I looked at the folders and there is only one sqlite3 file.  The Database 
Structure is unchanged and the original data is still intact.  The admin page 
now displays 2 Question tables – the 2nd one contains no data.  Also, 
http://127.0.0.1:8000/polls2/ shows No Questions available.

 

 

 

I have probably messed up with models.py.  Any pointers please as how multiple 
apps can point to the same database?
