MongoDB's Data-Driven Dropdown

I have a database named Staff in mongoDB, which includes a collection called records. Within this collection, there is a field named workgroup that contains entries such as "management", "union", "support staff", and more.

My goal is to populate a dropdown list with the values from the workgroup field so users can select a value and retrieve all records associated with it.

Although I am able to retrieve the values using Ruby (verified through the console), I am facing challenges when trying to populate the dropdown list. Here is my current Ruby statement:

get '/workgroup' do
  Record.all.to_a.collect(&:workgroup).uniq.to_json
end

The JavaScript code snippet I attempted to use is as follows:

<script>
 //var json = 'http://localhost:4567/api/v1/workgroup';

 $(document).ready(function()
{
    $.getJSON("/api/v1/workgroup",function(obj)
   {
         $.each(json.records,function(key,value)
         {
             var option = $('<option />').val(value.workgroup);
        $("#dropDownDest").append(option);
})
  })

         });

</script>

Once the dropdown is populated, my plan is to utilize the selected value to fetch and display all records with that specific workgroup in a table. I have yet to figure out that part, but I am taking it one step at a time!

Thank you for your assistance!

When using the $.getJSON function, make sure that your callback correctly references the data being passed. In this case, the code is referencing json.records, but there is no json object in scope.

Instead of using json, it seems like you should be iterating over the obj parameter that is being passed to the callback. Consider using

$.each(obj, function(key, value)...
for proper iteration.
