AngularJs working with nested arrays within objects

Question

I'm trying to display information from child and parent data within a json object. Below is my data:

$scope.electionDetails = {
  id : 1,
  election_type: "CityCouncil",
  election_name: "City A City Council Elections
  candidates : [{
               id: 1,
               election_id: 1,
               position_id: 1,
               first_name: "John",
               last_name: "Doe"
               },
               {
               id:2,
               election_id:1,
               position_id:1,
               first_name: "Jane",
               last_name: "Doe"
               },
               {
               id:3,
               election_id:1,
               position_id:2,
               first_name: "Mike",
               last_name: "Doe" 
               },
               {
               id:4,
               election_id:1,
               position_id:2,
               first_name: "Mary",
               last_name: "Doe"
               }],
 positions : [{
             id:1,
             election_id: 1,
             position: "Seat 1"
             },
             {
             id:2,
             election_id:1,
             position: "Seat 2"
             }]

}

I want to display this data grouped, using angular like so:

City A City Council Elections

Seat 1

John Doe
Jane Doe

Seat 2

Mike Doe
Mary Doe

What is your question? Have you made an attempt to display the data? If so, can you post it here? — Oscar Gonzalez

I haven't attempted. I know how to use ng-repeat just not in a way that will group this data correctly. — aqwright31

I have a solution for you. It is also worth noting that you are missing an ending " and , at the end of the "election_name" property in your code you have posted — mhodges

Here you go. The HTML structure may not be exactly what you want, so you can change up what tags you use, but this is the basic idea using ng-if and ng-repeat to create lists of candidates for a given seat.

This is correct. You can also use the 'filter' filter, instead of ng-if docs.angularjs.org/api/ng/filter/filter

Agreed. If it were my application I would use filter, I was just trying to keep it as simple as possible for the OP. Great suggestion, though!

Thanks! I think I could I apply this with a filter now.
