Removing a model in rails (reverse of "rails g model Title...")

rails g model Rating user_id:integer message:string value:integer

How can I completely remove this model? Thanks

Solution 1:

When you generate a model, it creates a database migration. If you run 'destroy' on that model, it will delete the migration file, but not the database table. So before run

bundle exec rails db:rollback
rails destroy model <model_name>

For rails versions before 5.0 and higher use rake instead of rails

bundle exec rake db:rollback   
rails destroy model <model_name>

Solution 2:

Try this

rails destroy model Rating

It will remove model, migration, tests and fixtures

Solution 3:

For future questioners: If you can't drop the tables from the console, try to create a migration that drops the tables for you. You should create a migration and then in the file note tables you want dropped like this:

class DropTables < ActiveRecord::Migration
  def up
    drop_table :table_you_dont_want
  end

  def down
    raise ActiveRecord::IrreversibleMigration
  end
end
