How to create initial_data Json fixture for many-to-many relation?

Question

I am creating an initializing file for for my django project database. I am doing this using a file called initial_data.json which i have created. For example the following code (when syncdb is run) creates in the model Word a new row where name="apple":

[ { "model": "sites.word", "pk": 1, "fields": { "name": "apple" } } ]

I have managed to this so far for several models, the problem is with models that have a many-to-many field. I've looked around for the correct way to do this and have come up empty.

So, for example, if a Model mood has many Interests how would I write in the Json file that mood-1's interests are interest-1, interest-2 and interest-3.

What is the proper way to write in Json a models many-to-many relation?

EDIT:

@pastylegs solution was correct, I was just having trouble because the numbering of my interests was off in the Json file so it couldn't match them with there moods.

Answer 1

I'm pretty sure the manytomany field of your model can be written like a simple list:

 [
    { 
        "model": "sites.word", 
        "pk": 1,
        "fields": { 
            "name": "apple",
            "my_m2m_field_name": [1,2,3],
        }
     }
]

where 1, 2, 3 are the primary keys for the relations
