ActiveRecord attributes stored serialized in a json column, super smooth. Typed and cast like Active Record. Supporting nested models, dirty tracking, some querying (with postgres jsonb contains), and working smoothy with form builders. Use your database as a typed object store via ActiveRecord, in the same models right next to ordinary ActiveRecord column-backed attributes and associations. Your json-serialized attr_json attributes use as much of the existing ActiveRecord architecture as we can.

MetaWhere offers the ability to call any Arel predicate methods (with a few convenient aliases) on your Model's attributes instead of the ones normally offered by ActiveRecord's hash parameters. It also adds convenient syntax for order clauses, smarter mapping of nested hash conditions, and a debug_sql method to see the real SQL your code is generating without running it against the database. If you like the new AR 3.0 query interface, you'll love it with MetaWhere.

Scoped search makes it easy to search your ActiveRecord-based models. It will create a named scope :search_for that can be called with a query string. It will build an SQL query using the provided query string and a definition that specifies on what fields to search. Because the functionality is built on named_scope, the result of the search_for call can be used like any other named_scope, so it can be chained with another scope or combined with will_paginate. Because it uses standard SQL, it does not require any setup, indexers or daemons. This makes scoped_search suitable to quickly add basic search functionality to your application with little hassle. On the other hand, it may not be the best choice if it is going to be used on very large datasets or by a large user base.
