Ajax in rails

Rails
1

I am building a task management application in ROR. I am new to ROR and
learning it. While adding tasks, I need to select a projects drop down
list and the team members of that project will be shown as drop down. I
am using ajax for it. But I see that in the response data I am getting
the complete htmls with header (not only the drop down htmls). Please
help.

============_form.html.erb=============================

<%= select( “project”, “id”, { “abc” => “1”, “xyz” =>
“2”}),:onchange=>“getComboA(this)”%>

    function getComboA(sel)
 {
      var value = sel.options[sel.selectedIndex].value;
      $.get("/users_projects?id="+value,function(data) {
      alert(data);
      $("#user_1").html("<label>User Details</label>"+data);
      });
 }

=============Task Controller=================

def users_projects
    @projs = ProjectsUser.find_all_by_project_id(params[:id])
    @users=[]
    @projs.each do |pro|
    @users<<User.find(pro.user_id)
    end
end

===========users_projects.html.erb================

<%if [email protected]?%>
<%=select_tag :user_id,options_from_collection_for_select(@users,

“id”, “email”)%>
<%end%>

You need to specify to render without the outer layout in your
controller:

render :layout => false
