在流星中插入集合时出错

Question

I'm using meteor with SimpleSchema and Collection2. And react. I faced with error when inserting an item to the collection. here is the code:

my collection and schema in recipes.js:

import { Meteor } from 'meteor/meteor';
import { Mongo } from 'meteor/mongo';
import { SimpleSchema } from 'meteor/aldeed:simple-schema';

export const Recipes = new Mongo.Collection('recipes');

Recipes.deny({
  insert() { return true; },
  update() { return true; },
  remove() { return true; },
});

RecipeSchema = new SimpleSchema({
  name: {
    type: String,
  },
  description: {
    type: String,
  },
  author: {
    type: String,
    autoValue: function() {
      return Meteor.userId();
    },
  },
  createdAt: {
    type: Date,
    autoValue: function() {
      if(Meteor.isClient){
            return this.userId;
      } else if(Meteor.isServer){
            return Meteor.userId();
        }
    },
  }
});

Recipes.attachSchema(RecipeSchema);

My methods code in Methods.js

import { Meteor } from 'meteor/meteor';
import { Mongo } from 'meteor/mongo';
import { SimpleSchema } from 'meteor/aldeed:simple-schema';

import { Recipes } from './recipes.js';

 Meteor.methods({
   'recipes.insert'(name, desc) {
     new SimpleSchema({
       name: { type: String },
       desc: { type: String },
     }).validate({ name, desc });

     Recipes.insert({
       name,
       description: desc,
     });
   }
});

And in file AddRecipeForm.jsx in the handleSubmit method of the component I get the values of the inputs (name and desc) and then call Meteor.call('recipes.insert', name, desc); . I want field Author and CreatedBy to create automatically on the server with simple-schema autoValue.

But I have an error always when I am trying to inset something with the form:

insert failed: Error: Author is required

I tried to add this code to the recipe.insert method:

let newRecipe = {
  name,
  description: desc,
}

RecipeSchema.clean(newRecipe);
Recipes.insert(newRecipe);

But that didn't work. And in official simple-schema docs I've found that is not necessary:

NOTE: The Collection2 package always calls clean before every insert, update, or upsert.

I solved this problem as adding optional: true to the fields Author and CreatedAt in my RecipeSchema . so code for the author field is:

author: {
    type: String,
    optional: true,
    autoValue: function() {
      return this.userId;
    },
  },

But I don't want this fields to be optional. I just want to autoValue works and this fields will be filled with the right values. Who knows why this error occurs and how to solve it?

Update

I noticed one important moment. I inserted different recipies with my form (that i think is working wrong because of the optional: true ). when I run meteor mongo > `db.recipes.findOne()' and get different recipies, I get objects like these:

meteor:PRIMARY> db.recipes.findOne()

{
        "_id" : "RPhPALKtC7dXdzbeF",
        "name" : "Hi",
        "description" : "hiodw",
        "author" : null,
        "createdAt" : ISODate("2016-05-12T17:57:15.585Z")
}

So i don't know why, but fields Author and CreatedBy are filled correct (author: null beacuse i have no accounts system yet). but in this way, what is the meaning of required and optinal in schema? is my solution (with optional: true ) correct?

update 2

another important moment! i removed author field from the schema. and removed optional:true from the createdBy field. and it works! tithout optional true. I realized that actual problem is in **author field* of the schema. but WHAT is the problem?

Answer 1

This is internal Framework issue, I guess. Your First code looks perfectly alright. Instead of posting this question here, you can post it on aldeed: collection2 github repository. The concerned people who maintain it will look into the issue.
