Building associations with Autoform and Collection2

Hi, this is my code below:

  • I am using the autoform and collection2 packages.

  • I 've created 2 mongo collections (‘Bambinos’ and ‘Associazioni’)

  • Can you please indicate how should I set the field ‘associazione’ within the ‘Schema.Bambinos’ in order
    to get multiselection field showing only the ‘Associazioni’ records belonging to the Associazioni collection ? I would like to get the same effect as in the ‘status’ field without hardcoding the allowed values but getting them from an association between the 2 collections.
    I hope the question is clear. Thank for your support

    Schema = {};

    Bambinos = new Mongo.Collection(“bambinos”);

    Associazioni = new Mongo.Collection(‘associazioni’,{
    schema: {
    name: {
    type: String,
    label: “Associazione”
    }
    }
    });

    Schema.Bambinos = new SimpleSchema({
    nome: {
    type: String,
    label: “Nome”,
    max: 200
    },
    cognome: {
    type: String,
    label: “Cognome”
    },
    status: {
    type: String,
    label: “Status”,
    allowedValues: [“segnalato”,“in prova”,“inserito”,“sospeso”,“abbandono”,“terminato”],
    autoform: {
    afFieldInput: {
    firstOption: “(Seleziona uno stato)”
    }
    }
    },
    dataDiNascita: {
    type: Date,
    label: “Data di nascita”,
    min: 0
    },
    luogoDiNascita: {
    type: String,
    label: “Luogo di nascita”
    //optional: true
    },
    disciplina: {
    type: String,
    label: “disciplina”,
    allowedValues: [“atletica”,“basket”,“calcetto”,“calcio”,“danza”,“nuoto”,“pallavolo”,“rugby”],
    autoform: {
    afFieldInput: {
    firstOption: “(Seleziona uno sport)”
    }
    }
    },
    associazione : {
    type: ??? ,
    allowedValues: ???,
    autoform: {
    afFieldInput: {
    firstOption: “(Seleziona una associazione)”
    }
    }
    },

    });

    Bambinos.attachSchema(Schema.Bambinos);
