Use models outside a view

To send emails and stuff, I use code outside the views.py file (too much code there). I created a file named "tools.py" in the app folder where I start with

from django.shortcuts import render_to_response
from django.core.mail import send_mail

from mysite.myapp.models import MyModel

With runserver, I have an error ImportError: cannot import name MyModel

This is strange as I use the same import in the views.py file and there is no problem...

Any idea ? Thanks

A couple of things:

  • Make sure you have your init.py file in the folder where your "tools.py" file is located, this is a common reason why something might not be found.

I'm working on setting up something that requires something very similar to your requirements.

If you are trying to have this as a on/off process eg.) cronjob, worker etc. Do the following.

#!/usr/bin/env python
######################################################################### 
# Required DO NOT REMOVE
#########################################################################
import os
import sys

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "appname.settings")
#########################################################################

# Import My Models, or Run an Include to Handle Processing.
from app.models.model import *

# Do Stuff to Test ( I suggest a simple insert into the model or pull and return content )

Save this file in the same folder that your "manage.py" is saved in, you can call this directly and it should process, you can setup a cronjob for it to run, etc. This allows you to have a little less code as it doesn't run some of the processes that django runs prior to rendering a view from the urls.py file.

If this is unclear please feel free to comment and I will edit with correction or further details.

All the best

Most likely, you have a circular import. Are you importing this tools.py file in your myapp/models.py?
