MigrationQueries

The migration_queries gem improves tracking of migration queries in Ruby on Rails applications. It provides a simple way to log and analyze the SQL queries generated by ActiveRecord migrations, helping developers optimize their database interactions.

Add this gem to development dependencies in your Gemfile:

group :development do
  gem 'migration_queries'
end

Then, run bundle install to install the gem.

The gem is going to automatically track migration queries executed by ActiveRecord. You can view the logged queries in your Rails console or in the log files.

Example migration file after running migration and logging queries:

class AddExampleTable < ActiveRecord::Migration[6.0]
  def change
    create_table :example do |t|
      t.string :name
      t.timestamps
    end
  end
end
=begin Migration Queries
CREATE TABLE "example" ("id" bigserial primary key, "name" character varying, "created_at" timestamp(6) NOT NULL, "updated_at" timestamp(6) NOT NULL)

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
