It's not very different to member action
class InvoicesController < ApplicationController
active_scaffold do |config|
config.action_links.add :show_export, :type => :collection, :position =>
:top
end
def show_export
respond_to_action(:show_export)
end
def export
process_action_link_action do
if range_selected
from = ...
to = ...
end
do_export(from, to)
end
end
protected
def show_export_respond_to_js
render :partial => 'show_export'
end
def export_respond_to_html
render :partial => 'email'
end
end
# show_export.html.erb
<div class="active-scaffold">
<div class="show_export-view <%= "#{id_from_controller
params[:controller]}-view" %> view">
<%= render :partial => 'show_export' -%>
</div>
</div>
# _show_export.html.erb
disable xhr becuase we want to return file, so ajax must not be used
<%= render :partial => "base_form", :locals => {:form_action => :export,
:body_partial => 'show_export_form',
:xhr => false,
:headline => "Export"} %>
