How to use other Model in data source?

I tried to use mongoose

// Model
const Model1 = mongoose.model('col1', Schema1)
const Model2 = mongoose.model('col2', Schema2)


// Data source
export default class Data1 extends MongoDataSource {
  getData1(name) {
    // How to use `Model2`
    return this.model.findOne({ name: name })
  }
}
........................

// Apollo server
...........
dataSources: () => ({
    data1: new Data1(Model1),
    data2: new Data2(Model2),
  }),

How to use Model2 in DataSource1 (Data1)?

Very thanks again 👍

You might be able to use context inside the getData method in the Data1 class.

class Data1 extends DataSource {
  getData(x) {
    this.context.dataSources.data2.getData(x)
  }
}
