Instance Method Details

#schema(*args) ⇒ Object

Define a schema on your ActiveRecord model.

schema :name, { :age => :integer }, { :birthdate => :datetime }, :summary

Table + columns will be added automatically based on your definition.

If you remove a column, it will be removed from the table the next time the class is loaded.

If you change the type of a column, it will be also be updated the next time the class is loaded.

Likewise, adding a new column will add the column to your schema on the next class load.

Columns with no types are assumed to be strings.
