Adding comments in meteor. Error : 'insert failed'

Question

过去几个小时我一直在苦思冥想。我知道我犯了一个愚蠢的错误，但我似乎无法让代码正常工作。我不断收到 insert failed: Error: fritkotId is required 错误。任何帮助将不胜感激。

我正在尝试将评论功能添加到我的一个对象中。这就是我现在拥有的...

    +comments

newComment.js

import './newComment.tpl.jade'

Template.newComment.events({
    'click .form-save': (e) => {
        e.preventDefault();

        let body = $('.new-comment').val();


        Comments.insert({
            // check(id, String);
            body: body,
            createdAt: new Date()
        });

        console.log('A comment was inserted with this text: ' + body);
        Session.set('newComment', false);

        // FlowRouter.go('fritkotSingle');
        // console.log('redirecting');
    },
    'click .form-close': (e) => {
        e.preventDefault();

        Session.set('newComment', false);
    }
})

我认为我的问题要么出在我的架构定义上，要么出在我在 newComment 表单上调用插入的方式上。我需要以某种方式将 fritkotId 传递给我的评论并在我保存时将其插入，但我在定义它的位置时遇到了问题。

Answer 1

Meteor 的 Session.get(key) 方法只接受一个参数。看来您正在为 fritkot.autoValue 条目的模式中的 Session.get() 方法传递两个参数：

fritkot: {
  type: String,
  label: 'fritkotId',
  autoValue: function() {
    return Session.get('fritkotId', this._id)
  },
  autoform: {
    type: 'hidden'
  }
},

您最有可能想做的事情：

fritkot: {
  type: String,
  label: 'fritkotId',
  autoValue: Session.get('fritkotId'),
  autoform: {
    type: 'hidden'
  }
},

Answer 2

编辑：所以问题出在我的 collection/comments.js 上。显然，在 SimpleSchema 和调用 Comments.insert 中声明不同的字段不允许我使用 fritkotId 添加评论。

我暂时把 SimpleSchema 定义注释掉了。

这是实际有效的代码。

Comments = new Mongo.Collection('comments')


// Permissions
Comments.allow({
    insert: (userId, doc) => {
        // return !! userId;
        return true
    },
    update: (userId, doc) => {
        return !! userId;
    },
    remove: (userId, doc) => {
        return !! userId;
    }
});


// Schema Definitions
// CommentSchema = new SimpleSchema({
//  body: {
//      type: String,
//      label: 'Body',
//      min: 1,
//      max: 140
//  },
//  author: {
//      type: String,
//      label: 'User',
//      autoValue: function() {
//          return this.userId
//      },
//      autoform: {
//          type: 'hidden'
//      }
//  },
//  createdAt: {
//      type: Date,
//      label: 'Created At',
//      autoValue: function() {
//          if (this.isInsert) {
//              return new Date()
//          } else if (this.isUpsert) {
//              return { $setOnInsert: new Date }
//          } else {
//              this.unset()
//          }
//      },
//      autoform: {
//          type: 'hidden'
//      }
//  },
//  lastUpdatedAt: {
//      type: Date,
//      autoValue: function() {
//          if (this.isUpdate) {
//              return new Date ()
//          }
//      },
//      denyInsert: true,
//      optional: true
//  } 
// });


// Methods
Meteor.methods({
    // updateComment: (id) => {
    //  Comments.update(id, {
    //      $set: { text:  }
    //  }),
    createComment: function (commentContent, fritkotId)  {
        check(commentContent, String);
        check(fritkotId, String);

        let currentUserId = Meteor.userId();

        if(currentUserId && fritkotId) {
            Comments.insert({
                body: commentContent,
                author: currentUserId,
                fritkotId: fritkotId,
                createdAt: new Date()
            });
        } else {
            throw new Meteor.Error('you must comment on a fritkot');
        }
    },
    updateComment: (id) => {
        // Session.set('editComment', true);
    },
    deleteComment: (id) => {
        Comments.remove(id);
    }
})

// Comments.attachSchema( CommentSchema );

不，我需要让它与 SimpleSchema

一起使用
