如何仅在不保存 nodejs 的情况下验证记录 |sailsjs |吃水线 [英] How can I validate a record only without saving in nodejs | sailsjs | waterline

问题描述

我寻求这种性质的东西

//validation rules in model "User"
attributes: {
    age: {
        required: true,
        type: 'numeric'
    }
},    

//now in controller, i want to be able to do this
Recipe.validate({age: 'An invalid age because it is a string. I except a validation error as response'});

问题是，它不起作用..它抱怨 beforeValidate 不可用，例如

Problem is, it doesn't work.. it complains about beforeValidate not being available, e.t.c

推荐答案

您需要将回调传递到 .validate 中:

You need to pass a callback into .validate:

Recipe.validate({age: 'blah'}, function(err){
  if (err && err.invalidAttributes) {
    console.log(err.invalidAttributes); 
  } else {
    // model is valid
  }
});
