[ghost]

Implemented m2m fields. Closes #61

Try importing this network topology (use FETCH strategy, then tell the application to update it either via the admin or the management command): https://openwisp.nnxx.ninux.org/api/topology/36d5ba3e-1364-49d2-9e29-1f6dceb7cbbb/?format=json

The visualization will fail.

I have imported this before trying the patch. After applying the patch I cannot run the fetch operation anymore as well.

I ran the tests and it worked for me-

@Weirdo914 try this:

1. Delete database
2. Checkout to master
3. Create this topology: https://openwisp.nnxx.ninux.org/api/topology/36d5ba3e-1364-49d2-9e29-1f6dceb7cbbb/?format=json
4. Go back to your branch
5. Make migrations
6. Look at the topology, it'll have no links.
7. Update topology (using admin or management command.)
8. Look at the topology graph again!

Looks like build is failing because of https://github.com/openwisp/django-netjsongraph/commit/a4bd9c69bf766c7782f48a262a5b379069d19783

I made some migrations for this.

@nemesisdesign That is strange because I looked at it before but when I tried it only showed 5 queries for me.

You can write a test for it to be 100% sure: https://docs.djangoproject.com/en/dev/topics/testing/tools/#django.test.TransactionTestCase.assertNumQueries

I tried testing it and it actually made 47 sql queries so I used JsonField instead, like you earlier suggested.
