Question

我正在使用以下元素创建Ember Data模型。是否可以将invoiceRows中的equalTo设置为新创建的发票的id？

model: function() {
  return Ember.RSVP.hash({
    parameter: this.store.findRecord('parameter',1),
      invoice: this.store.createRecord('customerinvoice',{
        order_reference : '',
        ordernr_bol: '',
        payment_method: '',
        invoice_type: '',
        company_name: '',
        customer_city: '',
        customer_country: '',
        customer_email: '',
        customer_first_name: '',
        customer_name: '',
        customer_phone: '',
        customer_phone_mobile: '',
        customer_postal_code: '',
        customer_street_nr: '',
        customer_vat_number: '',
    }),
    customers: this.store.findAll('customer'),
    invoiceRows: this.store.query('customerinvoicerow', {
      orderBy: 'id_cust_invoice_fb',
      equalTo: **THIS MUST BE ID OF CREATED INVOICE ???????**
    }),
    products: this.store.findAll('product')
  });
}

没有查看商店和序列化程序的代码，我可以建议首先创建记录，然后从中提取id并将其用于剩余的承诺：

model: function() {
  // create the invoice first
  const invoice = this.store.createRecord('customerinvoice', { /* ... */ });

  // then create the promises
  return Ember.RSVP.hash({
    parameter: this.store.findRecord('parameter', 1),
    invoice, // pass the invoice here
    customers: this.store.findAll('customer'),
    invoiceRows: this.store.query('customerinvoicerow', {
      orderBy: 'id_cust_invoice_fb',
      equalTo: invoice.get('id') // Extract the ID here
    }),
    products: this.store.findAll('product')
  });
}

另一件事，您可以为ember模型定义默认值，而不是创建初始化为空字符串的所有customerinvoice属性，如果省略属性，则会添加这些默认值：

export default Model.extend({
  order_reference: attr('string', { defaultValue: '' })
  // rest of the properties and their default values...
});

然后你可以创建一个记录而不传递任何东西。

this.store.createRecord('customerinvoice');

从创建的记录howto中获取带有id的数据模型？
