I want a method in app/controllers/application.rb that can prepend/append text to whatever template gets rendered. Of course I can't call render twice w/o getting a double render error, so is this possible?
I want to redirect after a delay using a meta refresh. Here's what I've got:
app/controllers/application_controller.rb:
def redirect_after_delay (url, delay) @redirect_delay = delay @redirect_url = url render end
app/views/layouts/application.html.erb
<!DOCTYPE html> <html lang="en"> <head> <%= yield :refresh_tag %> </head>
<body> <%= yield %> </body> </html>
So then if I want to add a redirect-after-delay, I add the following to 1) my controller and 2) the action's view:
app/controllers/my_controller.rb
def my_action redirect_after_delay 'http://www.google.com', 3 if some_condition end
app/views/my_controller/my_action.html.erb
<% content_for :refresh_tag do %> <meta http-equiv='refresh' content='<%=@redirect_delay%>;url=<%=@redirect_url%>'> <% end %> <h1>Please wait while you are redirected...</h1>
Since the content_for block never changes, would be nice to just call something from the redirect_after_delay method to add it to whatever template is going to be rendered.
