Ruby on Rails: Action without View

Answer 1

Have a look at http://guides.rubyonrails.org/layouts_and_rendering.html#using-render

You might need render :nothing => true

EDIT: misread your question, render :text => "yourtext" should fit your needs

Answer 2

In Rails 5 you need to use 'plain':

render plain: params[:email]

Answer 3

You'd need something like this:

def mcsubscribe
  # Do something to unsubscribe
  respond_to do |format|
    format.html { redirect_to(success_page) }
    format.js   { render :text => params[:email] }
  end  
end

If ajax is used, the params[:email] is send as text. If a HTML format is required (ie user clicked a link or filled in a regular form) a redirect is issued to tell the user the subscription has been successful.

Answer 4

Using

print params[:email]

will just print that value to the application logs, not into the response.

You want this:

render :text => params[:email]
