ombulabs/activerecord_search

An easy way to write LIKE / ILIKE queries for Active Record models

activerecord_search

This gem extends the ActiveRecord predicate builder to allow writing LIKE/ILIKE queries without writing raw SQL.

Usage

Add to your Gemfile:

gem 'activerecord_search'

Then you can write queries like this:

users = User.where(name: Search('ji'))
  # Returns users "Jim" and "Benji"
users = User.where(name: Search(ends_with: 'ji'))
  # Returns user "Benji"
users = User.where(name: Search(starts_with: 'ji'))
  # Find user "Jim"
users = User.where(name: Search(like: 'b%i'))
  # Find users "Benji" and "Banh Mi"

Internally, it uses the Arel matches node, which becomes ILIKE for Postgres and LIKE for other databases. In general, this should be case insensitive.
