✅

This line is critical:

collection = fields.ToManyField('maps.api.resources.CollectionResource', \
                 attribute='collections', full=True, null=True)

What it is saying is to look for collections attribute in User model and then represent each of those using CollectionResource. In other words, you should make sure that that your User model has collections attribute. For that, your Collection model has to have a foreign key with related_name:

from django.contrib.auth.models import User
def Collection(models.Model):
    ...
    user = models.ForeignKey(User, related_name='collections')

If you have that, Tastypie should be able to get the collections and display them in your UserResource.
