Allow posting a model with single related model

[mkuprionis]

I.e. when relation is many-to-one or one-to-one (model being posted belongs-to or has a related object).

Current implementation expects to get a list of related objects.

You should look at the docs more carefully. you can use uselist=False to create an one-to-one relationship. http://packages.python.org/Flask-SQLAlchemy/models.html#one-to-many-relationships

Please check the changeset.

There's no problem with SQLAlchemy nor with defining one-to-one relationship, problem is with what Flask-Restless expects relationship to be. Currently it expects that if I post model with a relation, that relation must be a list of related objects. So trying to POST data like below will fail:

{
  'vendor': u'Apple', 
  'name': u'iMac', 
  'owner': {'name': u'John', 'age': 2041}
}

Thanks for this, I will check it out, test it, and then pull it in.
