Using hooks in Redmine for Rails
===

I am writing a plugin in redmine and I need to use hooks. I have very basic understanding of hooks, so not sure how to use them in the current context. 

I want to display a view file or a partial on the main page of redmine.

I have put following lines in `init.rb`

    menu :application_menu, :displayissue, { :controller => 'summarywidget', :action =>    'index' }, :caption => 'Time Widget'

This creates a menu item on the application menu. Clicking this menu item I can see the view page. But I want to see this view page (as a partial) on the main page of redmine and not in the scope of plugin.

Redmine Version i am using is 1.3.*

Are hooks best for this requirement? Or is there any other approach?
