Module: Aurita::GUI::Form_Field_Helper

Included in:
Form
Defined in:
lib/aurita-gui/form/template_helper.rb

Overview

Provides wrapper methods for every form field type. Include this module in your template helper class.

Form_Helper methods each return a string for a respective Form_Field element. Rendering respects the form instances’ @field_decorator, but not @content_decorator, so you have to wrap form contents manually in your helper method.

Example: (what your template helper could look like)

module Form_Helper_Class_Methods
  def form_for(params, &block)
    form = Form.new(params, &block)
    render form.header_string        # <form ...> tag is prepared by form instance
    render '<ul class="form_fields">'   # begin content wrap
    yield(form)
    render '</ul>'                      # end content wrap
    render '</form>'                 # Closing tag for a form should always be </form>
  end
end

Usage, e.g. in ERB templates: 

<% form_for(:action => '/where/to/send') do |f| %>
  <%= f.text(:name => :title) { 'Value for this field' } %>
  <%= f.select(:name => :color, :options => [ :blue, :red, :green ], :value => :red)
<% end %>

Form_Helper automatically extends Aurita::GUI::Form when included.
