Set another layout for contact_us page views

[RedaBenh]

Hi, Is it an easy way to change the layout of the page.

example of rails app:

class PageController < ApplicationController
  layout "empty"
end

[RedaBenh]

An other solution is to create a task to contact_us gem. The new task will be bundle exec rake contact_us:copy_controllers so we can customize controller (like devise gem)

@RedaBenh well I think if you'd like you could add it as a configuration option, but a simpler approach could probably be to just use something like class eval. For example in your config/initializers/contact_us.rb file you could try adding to the bottom of it:

ContactUs.setup do |config|
end

ContactUs::ContactsController.class_eval do
  layout 'your_layout'
end

Let me know if that works out or you run into an error it's probably something trivial I'm missing or just a bad order in the initialization process.

i find one solution : copy the ContactsController to my local file ! but it's not a best practice :(

[JDutil]

Yea so that's because of trying to write the class_eval at the wrong point in the initialization process. Here is an article about the approach I'm suggesting http://www.refinerycms.com/guides/extending-controllers-with-decorators

I think you could move that class eval code to a file say: app/controllers/contact_us/contacts_controller_decorator.rb

That should hopefully call it after the contact us engines code has been initialized unless theres some other initialization issue I'm not thinking of.

Great ! it's exactly what i need
