sailsjs"错误:将模型转换为对象时出错."

Question

sailsjs 0.11,节点0.12.4.护照0.2.1和护照本地1.0

使用sailsjs蓝图路线只是为了看看发生了什么.该项目只是一个简单的博客,我尝试在蓝图路径/user/4中查看用户配置文件,向我显示用户ID 4.此消息是结果.

是什么原因引起了这个？

注意:我没有靠近帆/水线源.

和User.js模型.toJSON已注释掉,因为该消息最初指向该部分.在评论之后,第3行(at User.attributes.toJSON)现在是不同的.

var bcrypt = require ('bcrypt')
var User = {

    attributes: {
        email: {
            type: 'email',
            required: true,
            unique: true
        },
        password: {
            type: 'string',
            minLength: 6,
            required: true
        },
        admin: {
            type: 'boolean',
            defaultsTo: false // separate from acl
        },
        acl: {
            type: 'string',
            defaultsTo: 'USER' // MOD, USER (unlogged should get GUEST)
        }
/*
        toJSON: function() {
            var obj = this.toObject();
            delete obj.password;
            return obj;
        }
*/
    },

    beforeCreate: function(user, cb) {
        bcrypt.genSalt(10, function(err, salt) {
            bcrypt.hash(user.password, salt, function(err, hash) {
                if (err) {
                    console.log(err);
                    cb(err);
                } else {
                    user.password = hash;
                    cb();
                }
            });
        });
    }
};

module.exports = User;

[$ E]经过进一步审查后,我进行了一个对象到字符串的转换并在几个点输出它.try语句第一行的对象和subsequestn catch语句的第一行是:

  waterline:toObject > this.object TRY=

>>>
email: admin@admin.com
password: $2a$10$bNktAvahfa3f8Q8lTV262u9RrLUqdvp7SzfM6dQqki3YliXdLMWxK
admin: true
acl: USER
createdAt: Fri May 29 2015 23:25:35 GMT+0000 (UTC)
updatedAt: Fri May 29 2015 23:25:35 GMT+0000 (UTC)
id: 1
_locals: [object Object]
<<<

 +2ms
  waterline:toObject > this.object CATCH=

>>>
email: admin@admin.com
password: $2a$10$bNktAvahfa3f8Q8lTV262u9RrLUqdvp7SzfM6dQqki3YliXdLMWxK
admin: true
acl: USER
createdAt: Fri May 29 2015 23:25:35 GMT+0000 (UTC)
updatedAt: Fri May 29 2015 23:25:35 GMT+0000 (UTC)
id: 1
_locals: [object Object]
<<<

(这个输出不应该是json,它只是一个转储)

除非有人有更好的想法,否则我想我会继续转向sailsjs问题跟踪器.

Answer 1

我遇到了这个问题，在经历了巨大的麻烦之后，我终于设法解决了它（我认为现在修复这个错误所花费的时间与最初构建应用程序所花费的时间一样长......）

在没有看到您的控制器代码的情况下，我不知道这是否会为您解决问题，但对我来说，问题toJSON似乎发生在将用户模型输入部分时。我发现在将模型传递给渲染函数之前将模型显式渲染为 JSON 可以解决这个问题。

换句话说，我改变了这一点：

res.render('partials/user-card', user, function(err, html){
  partialData      = user.toJSON();
  partialData.html = html;

  // Send out a message (with HTML fragment) to socket subscribers
  User.publishUpdate(user.id, partialData);
});

...对此：

partialData = user.toJSON();

res.render('partials/user-card', partialData, function(err, html){
  partialData.html = html;

  // Send out a message (with HTML fragment) to socket subscribers
  User.publishUpdate(user.id, partialData);
});

（即，将 user.toJSON 从渲染函数的回调中移出，并将 JSON 而不是模型本身提供给渲染函数）。这也让我保留了删除密码的toJSON方法。
