Rails: Multi-submit buttons in one Form

by

This was covered in Railscast episode 38. Using the params hash to detect which button was clicked is the correct approach:

View:

<%= submit_tag 'Create' %>
<%= submit_tag 'Create and Add Another', name: 'create_and_add' %>

Controller:

if params[:create_and_add]
  # Redirect to new form, for example.

else
  # Redirect to show the newly created record, for example.
end
