我该如何解决?

我研究了类似的错误,但是我的模型都没有default属性,包括上面显示的phone模型。为什么会发生这种情况,我该如何解决?

解决方案

因此事实证明,.update()的水线调用会更改输入信息。我已经编写了一个用于创建或更新水线模型的函数,当他们解决了autoupdate_at问题时,他们必须更改了传入的信息。

我之前的无效代码:

createOrUpdate: function(model, primary, data){
  return model.update(primary, data)
  .then(function updateCB(updated){
    if (updated.length == 0){
      return model.create(data) //data here had an added updated_at field
      .then(function(created){
        return created;
      });
    }

    if (updated.length > 0){
      updated = updated[0];
    }
    return updated;
  });
}

有效的新代码:

createOrUpdate: function(model, primary, data){
  const data1 = JSON.parse(JSON.stringify(data)); // deep copy
  const data2 = JSON.parse(JSON.stringify(data)); // deep copy
  return model.update(primary, data1)
  .then(function updateCB(updated){
    if (updated.length == 0){
      return model.create(data2)
      .then(function(created){
        return created;
      });
    }

    if (updated.length > 0){
      updated = updated[0];
    }
    return updated;
  });
}


您不能通过以下方式致电更新:

1
updated_at: Sun Nov 27 2016 16:59:45 GMT-0800 (PST)

Updated_at是自动填写的字段。从请求中删除它(调用时称为调用),它将起作用。
