Overview

Generates a Formtastic form partial based on an existing model. It will not overwrite existing files without confirmation.

Examples:

$ rails generate formtastic:form Post

Copy the partial code to the pasteboard rather than generating a partial

$ rails generate formtastic:form Post --copy

Return HAML output instead of ERB

$ rails generate formtastic:form Post --haml

Generate a form for specific model attributes

$ rails generate formtastic:form Post title:string body:text

Generate a form for a specific controller

$ rails generate formtastic:form Post --controller admin/posts
