Rails - Feb 2012 - respond_to format.json not being called

Hi all,

I''m submitting a form using jQuery, but in the respond_to block only
the
format.html action is called.

This is the javascrip:

send_button.on(''click'', function(){
  var form =
$(this).closest(''.modal'').find(''form'');

  $.post(''/messages'', form.serialize(),
    function(data, status, xhr){
      console.log(data);
    });
  );
});

However, when this hits the controller, ''console.log(data)''
outputs html
(either root_url or the validation array).

The code in the controller looks like:

respond_to do |format|
  if @m.save
    format.html {redirect_to root_url, :notice=>"Message sent"}
    format.json {render :json=>@m, :status=>:created, :location=>@m}
  else
    format.html {render :action=>:new}
    format.json {render :json=>@m.errors,
:status=>:unprocessable_entity}
  end
end

Obviously, I''m not using link_to_function or anything, so I''m
wondering
if the request format header isn''t being set properly without using the
built-in rails functions?

Any help would be appreciated.

Many thanks.

	You call pure Javascript request.

	format.json - is NOT javascript hook,

	use format.js

	or old approach:
	if request.xhr?
		do action
	end
