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.

     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}

  format.json - is NOT javascript hook,

  use format.js

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