Droptable Rails is a Ruby gem that provides a simple way to drop database tables in Ruby on Rails applications. It allows developers to easily drop tables in a Rails application without having to manually delete them from the database.
To install Droptable Rails, simply add it to your Gemfile:
gem 'droptable_rails'
Then run bundle install
to install the gem.
Once Droptable Rails has been installed, dropping tables is incredibly simple. Droptable Rails provides a generator that creates drop_table
migration files.
To create a new drop_table
migration, simply run:
rails generate droptable MyTable
This creates a new migration file in the db/migrate
directory that drops the table my_table
. You can then run the migration as usual:
rake db:migrate
By default, Droptable Rails will only drop tables if the Rails environment is set to development
. To configure Droptable Rails to drop tables in other environments, you can specify the environments in the config/environments/development.rb
file:
DroptableRails.environment = [:development, :staging]
In this example, tables will be dropped in both development
and staging
environments.
Droptable Rails is a simple and efficient way to drop database tables in Ruby on Rails applications. With just a few simple commands, developers can easily drop tables without having to manually delete them from the database.
