如何在 Bookshelf.js 中创建与自定义字段名称的多对多关系？

Question

我想在 Bookshelf.js 中创建多对多关系，并想自己指定 FK 列的名称。我也希望能够访问 Bookshelf 中的 helper-table，类似于：

var Doctor = bookshelf.Model.extend({

  patients: function() {
    return this.belongsToMany(Patient).through(Appointment);
  }

});

var Appointment = bookshelf.Model.extend({

  patient: function() {
    return this.belongsTo(Patient);
  },

  doctor: function() {
    return this.belongsTo(Doctor);
  }

});

var Patient = bookshelf.Model.extend({

  doctors: function() {
    return this.belongsToMany(Doctor).through(Appointment);
  }

});

我该怎么做？

Answer 1

考虑到上面的例子，可以这样做：

var Doctor = bookshelf.Model.extend({

  tableName: "d_doctor",
  idAttribute: "d_doctorid",

  patients: function() {
    return this.belongsToMany(Patient).through(Appointment,"a_d_doctorid","a_p_patientid");
  }

});

var Appointment = bookshelf.Model.extend({

  tableName : "a_appointment",
  idAttribute : "a_appointmentid",

  patient: function() {
    return this.belongsTo(Patient,"a_p_patientid");
  },

  doctor: function() {
    return this.belongsTo(Doctor,"a_d_doctorid");
  }

});

var Patient = bookshelf.Model.extend({

  tableName : "p_patient",
  idAttribute : "p_patientid",

  doctors: function() {
    return this.belongsToMany(Doctor).through(Appointment,"a_p_patientid", "a_d_doctorid");
  }

});
