About

Indexes play such an important role in database development that it’s worth devoting some additional time to learn these features.
You will be able to see indexes in real-time bottom of every page.
Just trace your logs and add/remove database indexes on the fly!

Usage

Put the setting into config file config/environments/development.rb:

config.middleware.use 'DbIndexes'

Just add table name and column name.
Examples:

Table "banners", column "street" #one-column
Table "banners", column "street_city" #one-column
Table "banners", column "street_city_format" #multiple-column
