Overview

Usage

This generator generates a migration, a model and a controller.

rails g inline_forms Model attribute:type [attribute:type ...] [options]

Read more about the possible types below.

Overriding Rails::Generators::GeneratedAttribute

When using a generator in the form

rails g example_generator Modelname attribute:type attribute:type ...

an array with attributes and types is created for use in the generator.

Rails::Generators::GeneratedAttribute creates, among others, a attribute_type. This attribute_type maps column types to form attribute helpers like text_field. We override it here to make our own.
