This module enables Views to use EntityFieldQuery as the query backend, allowing you to query all defined entity types and their fields, even the ones stored in non-sql storage such as mongodb. In fact, unless you are storing your fields in mongodb (or some other engine -- please let me know if you do!) this module is probably not really useful for you.
Note to developers: if you have custom field types, add
property_type to your
hook_field_info otherwise the contrib entity API module and consequently efq_views won't pick it up.
Current development is sponsored by 10gen.
