javascript - Rails 4: Dynamically rendering a form on the same page with AJAX -

i seem having trouble finding information on how go dynamically presenting forms on same view. mean is, example, user clicks "add sub-element" link on show view "element", , presented small form adding sub-element, , of course same type of thing editing existing sub-elements, on same show view using ajax/js/jquery or something.

i trying rest-in-place, no avail, have several nested objects (some within other nested objects), , doesn't seem work in-line-editing.

i believe lack of information coming using incorrect search terminology, appreciated point me in right direction.

thanks in advance.

there lot of different ways it, 1 using remote forms, railscasts example or detailed answer on question. call controller jquery , render (similar code here):

in javascript:

$(document.body).on('click', '#user-list-body', function (e) {     var url = '/get_user_list/     $.ajax({         url: url,         datatype: 'html',         type: 'get',         success: function(data){             $('#user_table tbody').append(data);         }      }); }); 

in controller (note: drastically simplified version):

  def get_user_list      @users = user.all     respond_to |format|       format.html { render :layout => false, :partial => 'users/users_list'}     end   end
