Question

Trying to display a list filtered by the ‘term’ in autocomplete

I have a rails 3 application that is using the jquery-ui auto complete function. I have reached the point where you can search for a list of users. However when I type the first few letters of a specified user the entire list appears(Not sure whether this is a problem with my Javascript or the project_list inside the controller), when only one user should appear. But I don’t want it to do this. From my understanding I have to take var term and filter my list by it however I don’t know how exactly to do this, Code below.

User controller.rb

def project_list  
   list=User.all.map{|i|i.full_name}
   arr= [].concat(list.sort{|a,b| a[0]<=>b[0]}).to_json
   render :json =>arr
end

Application.js

    $("#tags").autocomplete({

      minLength: 2,

    source: function(request, response) {

        $.ajax({

            url: "/managerlist",

            dataType: "json",

            data: {

                term: request.term

            },

            success: function(data) {

                var results = [];

                $.each(data, function(i, item) {

                    var itemToAdd = {

                        value: item,

                        label: item

                    };

                    results.push(itemToAdd);

                });

                return response(results);



            }

        });

    }

});

}

All users are being loaded in your controller calling User.all instead of this you should pass an parameter to your controller and then, perform a select.
