Edge ordering

[moret]

Hi.

I was looking for a way to order edges based on the parent document array, but couldn't find a way. For example, given a model with Person and Destinations and a database:

const destinations = [
  new Destination({name: 'London'},
  new Destination({name: 'Paris'},
  new Destination({name: 'Berlin'}
];

const people = [
  new Person({name: 'John', trips: [destinations[2], destinations[0]]}),
  new Person({name: 'Jane', trips: [destinations[1]]}),
  new Person({name: 'Jill', trips: [destinations[1], destinations[0]]})
];

and a query:

{
  people {
    name
    trips {
      edges {
        node {
          name
        }
      }
    }
  }
}

I would expect the result:

{
  "data": {
    "people": [
      {
        "name": "John",
        "trips": {
          "edges": [
            {
              "node": {
                "name": "Berlin"
              }
            },
            {
              "node": {
                "name": "London"
              }
            }
          ]
        }
      },
      {
        "name": "Jane",
        "trips": {
          "edges": [
            {
              "node": {
                "name": "Paris"
              }
            }
          ]
        }
      },
      {
        "name": "Jill",
        "trips": {
          "edges": [
            {
              "node": {
                "name": "Paris"
              }
            },
            {
              "node": {
                "name": "London"
              }
            }
          ]
        }
      },
    ]
  }
}

Is that currently possible with graffiti? I couldn't find a way to do it, nor to order in other collections. Thank you in advance for the attention!

@moret It's not currently possible to specify an order. It could be implemented by adding an orderBy enum type to arguments based on the fields of the type. We can add this feature request to our list, or you can send in a PR ;). Also, you can always do the ordering on the client side.

@tothandras I see. I would love to dive in and help with a PR, I'm just not sure if I will be able to right now. But I will keep an eye around. Thank you for your reply!

@moret Please take a loot at #61!

[moret]

@tothandras looks great! In my use case I still need to use the association array own ordering which got solved in memory on the client as you suggested, but the orderBy solved all other sorting cases. Thanks a lot for the attention to that! 8)

@moret Is it okay if I merge it as it is? :)

[moret]

@tothandras sure!

@moret #61 is merged and released under 4.3.0. ;)
