How to implement Single Table Inheritance (STI) when using decorators

[n-xt]

The manual shows how to use Single Tabel Inheritance using the static fields() method and using the spread operator calling super.fields(). But what when I am using decorators?

If you just want to have a simple extend then look there: #325

If you use types then yes i should have included an decorator example in the docs.
Here is an example:

    class Animal extends Model {
      static entity = 'animals'

      @Attr(null) declare id: number | null
      @Attr('animal') declare type: string

      static types() {
        return {
          animal: Animal,
          dog: Dog,
        }
      }
    }

    class Dog extends Animal {
      static entity = 'dogs'

      static baseEntity = 'animals'

      static fields() {
        return {
          ...super.schemas[super.entity],
        }
      }

      @Attr('dog') declare type
      @Attr('terrier') declare race: string
    }

Thanks, I am still facing issues. I have separated the models into their own files. You mentioned that there could be circular reference error - but the link in the manual does not work. How should this be handled? Maybe there are some more issues?

Yeah there seem to be some issues. I got it to work, but its not yet working the way you wrote it.
I had to change the save repo with passing the type because it doesnt work yet to use a child repo and having the right type.

Okay, I got it working now as I wanted:

• Querying the parent model "Resource" returns ALL data sets
• Querying a sub-model (Document / Image) only returns the data sets of that type
• I implemented each sub-model in its own file

Look here: https://codesandbox.io/s/single-table-inheritance-demo-21rukn?file=/src/App.vue

Thanks!

Great to help you out although its not that way it should be....i am still wondering how it works. you just commented the types out....Have to rethink all this.
