Module: Redmine::Hook::Helper

Included in:
ApplicationController, ApplicationHelper
Defined in:
lib/redmine/hook.rb

Overview

Helper module included in ApplicationHelper and ActionController so that hooks can be called in views like this:

<%= call_hook(:some_hook) %>
<%= call_hook(:another_hook, :foo => 'bar') %>

Or in controllers like:

call_hook(:some_hook)
call_hook(:another_hook, :foo => 'bar')

Hooks added to views will be concatenated into a string. Hooks added to controllers will return an array of results.

Several objects are automatically added to the call context:

  • project => current project

  • request => Request instance

  • controller => current Controller instance

  • hook_caller => object that called the hook
