rails_indexes
rails_indexes copied to clipboard
A rake task to track down missing database indexes. does not assume that all foreign keys end with the convention of _id.
h1. DEPRECATED
This gem doesn't really work on Rails 4 - no plans on upgrading it anyway. you probably should take a look at "lol_dba":https://github.com/plentz/lol_dba
h1. Rails Indexes
Rails indexes is a small package of 2 rake tasks that scan your application models and displays a list of columns that probably should be indexed.
Note: there may be more fields depending on your application design and custom queries.
h2. Rails 3.x and 4.x
If you're using Rails 3.x or 4.x, you probably should take a look at "lol_dba":https://github.com/plentz/lol_dba
h2. Installation
as a rails plugin:
script/plugin install git://github.com/eladmeidar/rails_indexes.git
h2. Usage
Display a migration for adding/removing all necessary indexes based on associations:
rake db:index_migration
Display a migration for adding/removing all necessary indexes based on AR::Base#find calls (including: find, find_by, find_all_by, find_by_x_and_y, find_all_by_x_and_y):
rake db:find_query_indexes
Note that it would probably make more sense running those tasks on production, where you actually need those indexes to be added.
h2. Tests
Requires SQLite3 installed, then just:
rake
to run the tests
