simple_form_object

SimpleFormObject

Allows you to make really simple non-persisted form objects or models.

Only suitable for Rails 4 applications.

You don't need to remember to:

• include ActiveModel::Model
• Set the class model_name so Rails url generation works for forms.

It gives you:

• Default values for your form attributes.
• Integration with simple_form so you don't need to specify the field type on the form.
• Thanks to ActiveModel::Model you can use standard Rails validations on your attributes.

Installation

Add this line to your application's Gemfile:

gem 'simple_form_object'

And then execute:

$ bundle

Usage

Create a form class. I like to put them inside app/forms/. If you prefer to create models then that will work too.

class PostForm
  include SimpleFormObject

  attribute :body, :text
  attribute :title, :string
  attribute :publish_date, :datetime, default: Time.now

  validates_presence_of :body
  validates_presence_of :title
end

SimpleFormObject includes ActiveModel::Model so you don't need to. It also intelligently sets the model_name on the class so that Rails routing works as expected. As an example:

<%= simple_form_for @post_form do |f| %>
  <%= f.input :title        # renders a simple string input %>
  <%= f.input :body         # renders a textarea %>
  <%= f.input :publish_date # renders a datetime select html element %>
<% end %>

Will create a HTML form which will POST to posts_path.

Todo:

• Automatically add good validations for types.
• It's tested in spec but better tests wouldn't hurt.
