Uber builder

The greatest form builder for Ruby on Rails.

Why is it great?

• Tabular forms
• ul / li css forms
• Easily extensible
• Comes with a few useful extensions already
• Comes with a FormBuilder compliant StaticBuilder to render any form built with it as static.

How do I harness this greatness?

To create a basic form:

<% form_for @user do |f| %>
  <h2>User details</h2>
  <% f.table do %>
    <% f.manual :label => "Name" do %>
      <%= f.text_field :first_name %>
      <%= f.text_field :last_name %>
    <% end %>
    <%= f.text_field :age %>
  <% end %>

  
Billing information
<% f.table do %>
<%= f.text_field :address %>
… etc.
<% end %>
<% end %>

This form, out of the box, will be rendered as a table (with a class of form). To make the labels line up, you’ll want to add some CSS:

table.form td.label {
  display:block;
  width:200px;
  font-weight:bold;
}

You can also render ul / li like so:

<% form_for @user do |f| %>
  <h2>User details</h2>
  <% f.ul do %>
    ...
  <% end %>
<% end %>

The ul is rendered with a class of “form”. You’ll need to add css styling to make it work. Good luck with that.

If you extract that to a partial, _form.html.erb, then you could use if as a static view or a form

# render it as a form
<% form_for @user do |f| %>
  <%= render :partial => "form", :locals => {:f => f} %>
<% end %>

# render it as static
<% form_for @user, :builder => StaticBuilder do |f| %>
  <%= render :partial => "form", :locals => {:f => f} %>
<% end %>
