reload() fails for references where dbref=False

[jkbrzt]

Test case:

from mongoengine import connect, Document, ListField, ReferenceField

connect('test')

class Author(Document):
    meta = {
        'collection': 'authors',
        'allow_inheritance': False
    }

class Post(Document):
    authors = ListField(ReferenceField(Author, dbref=False))

author = Author()
author.save()

post = Post(authors=[author])
post.save()

post.reload() # => mongoengine.base.NotRegistered:

Traceback:

File "test.py", line 22, in <module>

   File "mongoengine/mongoengine/base.py", line 135, in get_document
     """.strip() % name)
 mongoengine.base.NotRegistered: `Authors` has not been registered in the document registry.
             Importing the document class automatically registers it, has it
             been imported?

Hi thanks for the ticket. I'm on the road at the moment and will address
this on Monday.

The problem is that meta['collection'] is not honoured.

@jkbr thanks for the ticket - tricky one to nail that one - but fixed in the 0.7 branch
