When using ActionView::Base.new to render templates views

carlos_roque ยท Apr 17, 2018

when calling this method to render templates to a string. in order to use any helper methods you need to add them to the view like this 

view = ActionView::Base.new(ActionController::Base.view_paths, {})
view.class_eval do  
# include any needed helpers (for the view)
include ApplicationHelper
end
