Advanced Rails Studio: Custom Form Builder
Custom Form Builder
Use a custom form builder to clean up your html.erb files.
class LabelFormBuilder < ActionView::Helpers::FormBuilder
helpers = field_helpers +
%w{date_select datetime_select time_select} +
%w{collection_select select country_select time_zone_select} -
%w{hidden_field label fields_for} # Don’t decorate these
’ + super) #wrap with a paragraph end end
end
Then you can remove all the <p> and label tags from you form.
Editing user
<% form_for(@user, :builder => LabelFormBuilder) do |f| >
<= f.error_messages >
<= f.text_field :name >
<= f.text_field :address >
<= f.text_area :comment >
<= f.check_box :check >
<= f.submit “Update” >
< end %>
<%= link_to ‘Show’, @user > |
<= link_to ‘Back’, users_path %>
Add this to your application initializer to have all form use this form builder
ActionView::Base.default_form_builder = LabelFormBuilder
Then you can replace
<% form_for(@user, :builder => LabelFormBuilder) do |f| %>
with
<% form_for(@user) do |f| %>
Now the same form with no custom builder was looking like this before.
Editing user
<% form_for(@user) do |f| >
<= f.error_messages %>
<%= f.label :name %>
<%= f.text_field :name %>
<%= f.label :address %>
<%= f.text_field :address %>
<%= f.label :comment %>
<%= f.text_area :comment %>
<%= f.label :check %>
<%= f.check_box :check %>
<%= f.submit “Update” %>
<% end %>
<%= link_to ‘Show’, @user > |
<= link_to ‘Back’, users_path %>
