Ruby on Rails ActiveRecord Migrations Add a new column to a table
Example
To add a new column name to the users table, run the command:
rails generate migration AddNameToUsers name
This generates the following migration:
class AddNameToUsers < ActiveRecord::Migration[5.0]
def change
add_column :users, :name, :string
end
end
When the migration name is of the form AddXXXToTABLE_NAME followed by list of columns with data types, the generated migration will contain the appropriate add_column statements.
