How do Django Fixtures handle ManyToManyFields?
A foreign key is simple the pk of the object you are linking to, a manytomanyfield uses a list of pk's. so
[ { "pk":1, "model":farm.fruit, "fields":{ "name" : "Apple", "color" : "Green", } }, { "pk":2, "model":farm.fruit, "fields":{ "name" : "Orange", "color" : "Orange", } }, { "pk":3, "model":person.farmer, "fields":{ "name":"Bill", "favorite":1, "likes":[1,2], } }]You will need to probably write a conversion script to get this done. Fixtures can be very flimsy; it's difficult to get the working so experiment with a subset before you spend a lot of time converting the 30k records (only to find they might not import)
