How to use my view helpers in my ActionMailer views?





up vote3down votefavoriteI want to use the methods I defined in 
app/helpers/annotations_helper.rb
in my ReportMailer views (
app/views/report_mailer/usage_report.text.html.erb
). How do I do this?

Based on this guide it seems like the 
add_template_helper(helper_module)
 method might do what I want, but I can't figure out how to use it.

(BTW, is there a reason you get access to a different set of helpers in mailer views? This is pretty annoying.)

class ReportMailer < ActionMailer::Base
add_template_helper(AnnotationsHelper)

...
end

up vote0down voteThis might give you some direction, I have a method "check_options" defined in "app/helpers/app_helper.rb"

In my controller that renders the view "app/controllers/app_controller.rb" I have the following line

helper: all # include all the helpers all the time
and then finally in my view I just call the "check_options" like

<% if check_options ...
From the documentation link that you posted looks like you might need

helper(*args, &block)

Declare a helper:
"helper :foo"  requires ‘foo_helper’ and includes FooHelper in the template class.
Give this link a try as well http://caboo.se/doc/classes/ActionController/Helpers/ClassMethods.html there are some examples that might help

A small excerpt from the page

"By default, the controller will include a helper whose name matches that of the controller, e.g., MyController will automatically include MyHelper."

Cheers
