Hi guys,

Currently struggling with this. How did you set the priority of your seed files? I have multiple seeds in /config/seeds/ and one config/seeds.js file that requires them all.

Order for me is currently a big problem. Waterline is trying to form relationships between seeds that aren't yet instantiated.

I'm using the priority attribute on models in seeds. So like:

module.exports.seeds = {
  model1: {
    data: [
      {
        id: 1,
        field: "text1",
      },
      {
        id: 2,
        field: "text2",
      }
    ],
    unique: ["field"],
    priority: 1
  },
 model2: {
    data: [
      {
        id: 1,
        field: "text1",
      },
      {
        id: 2,
        field: "text2",
      }
    ],
    unique: ["field"],
    priority: 2
  }
}
