Re: How to use a ViewField

[Alexander Shorin]

Hi Jason!

There you'd missed one step to store defined view in CouchDB:

>>> City.by_typeiscity.sync(db)

The sync() method of ViewField (actually, ViewDefinition) stores
defined view within specified design document in CouchDB, so after
that you may execute it normally.

Looks like documentation have missed this process, but it's described
in couchdb.design module docs.
