[英]SimpleSchema insert fails with unhelpful error unless {validate: false} is set
至此,我实际上已经缩减了代码以模仿docs中的示例 ,并且遇到了同样的错误。
我已经这样定义了我的收藏:
var Categories = new Mongo.Collection('categories');
const CategorySchema = new SimpleSchema({
title: {
type: String,
label: "Title",
max: 255,
optional: true
},
created: {
type: Date,
label: "Date Category Created",
autoValue: () => {
if(this.isInsert){
return new Date();
} else if (this.isUpsert) {
return {$setOnInsert: new Date()};
}
}
},
updated: {
type: Date,
label: "Date Category Modified",
autoValue: () => {
if(this.isUpdate){
return new Date();
}
},
optional: true
}
});
Categories.attachSchema(CategorySchema);
export { Categories };
并有一个调用insert的方法:
Meteor.methods({
'categories.insert'(title){
check(title, String);
Categories.insert({title: title}, (err, res) => {
if(err){
console.error("Category insert failed: " + err);
}
});
},
...
在尝试解决此问题时,我已在规则定义中添加和删除了规则,有时会导致call stack exceeded
错误。 我得到的大部分是以下内容:

meteor.js?hash=27829e9…:930 Error invoking Method 'categories.insert': Internal server error [500]
编辑
换出箭头功能后:
methods.js
Meteor.methods({
// Settings: create new category
'categories.insert': function(title){
check(title, String);
Categories.insert({title: title}, function(err, res){
if(err){
console.error("Category insert failed: " + err);
}
});
},
...
settings.js
Template.settings.onCreated(function(){
Meteor.subscribe('categories');
});
Template.settings.helpers({
categories: function(){
return Categories.find();
}
});
Template.settings.events({
'click #newCategoryButton': function(e){
let title = $("#newCategoryInput").val();
if(title !== ""){
Meteor.call('categories.insert', title);
$("#newCategoryInput").val("").focus();
}
},
'click .removeCategory': function(e){
var id = $(e.currentTarget).data('id');
Meteor.call('categories.remove', id);
}
});
Categories.js
var Categories = new Mongo.Collection('categories', options);
const CategorySchema = new SimpleSchema({
title: {
type: String,
label: "Title",
max: 255,
optional: true
},
created: {
type: Date,
label: "Date Category Created",
autoValue: function(){
if(this.isInsert){
return new Date();
} else if (this.isUpsert) {
return {$setOnInsert: new Date()};
}
}
},
updated: {
type: Date,
label: "Date Category Modified",
autoValue: function(){
if(this.isUpdate){
return new Date();
}
},
optional: true
}
});
Categories.attachSchema(CategorySchema);
仍然收到与原始帖子相同的错误
您正在使用箭头函数,如评论中提到的Sean。 用传统的function(){...}
代替它们,您应该会很好。
