Ruby form_for explanation?

Can anyone tell me what is the difference between these two? I seem to get the same result

<%= form_for (@message) do |f| %>

vs 

<%= form_for Message.new, remote: true do |f| %>

remote: true is used to make the form submit happen via AJAX.

More info about this is available in Rails Guides (Courtesy Arup)

The other difference lies in the object @message. If it was initialized using existing data from the database, the form generated will come pre-filled

eg, If in the controller code is

@message = Message.new

Then the output of the two forms will be identical, but if the controller code is

@message = Message.find(params[:id])

then the form will be filled with values of @message
