我正在尝试使用React和Meteor将表单数据提交到数据库。
我有一个表单的AddDeal组件和交易的集合以及其中的一个方法。
错误
模拟调用'deals.insert'的效果时发生异常
ReferenceError:_id未定义
收到错误消息:单击提交时需要ID。
我不知道插入时如何处理_id。
这是我的代码,感谢您的帮助!
onSubmit(e)函数
onSubmit(e) {
e.preventDefault();
const title = this.state.title.trim();
const description = this.state.description;
const category = this.state.category;
const location = this.state.location;
const price = this.state.price.trim();
e.preventDefault();
if (title, description, category, location, price) {
Meteor.call('deals.insert', title, description, category, location, price);
}
alert('Title is: ' + this.state.title + 'Description is: ' + this.state.description + 'Category is: ' + this.state.category
+ 'Location is: ' + this.state.location + 'Price: ' + this.state.price);
this.setState({
title: '',
description: '',
category: 'technology',
location: 'USA',
price: '0.00'
});
}
插入方式
export const Deals = new Mongo.Collection('deals');
if (Meteor.isServer) {
Meteor.publish('deals', function () {
return Deals.find({ userId: this.userId });
});
}
Meteor.methods({
'deals.insert'(_id, title, description, category, price, location) {
if (!this.userId) {
throw new Meteor.Error('not-allowed');
}
new SimpleSchema({
_id: {
type: String,
min: 1
},
title: {
type: String,
optional: true
},
description: {
type: String,
optional: true
},
category: {
type: String,
optional: true
},
location: {
type: String,
optional: true
},
price: {
type: Number,
optional: true
}
}).validate({
});
Deals.insert({
_id,
title,
description,
category,
location,
price,
createdAt: Date(),
userId: this.userId
});
}
});
最佳答案
在deals.insert
上,您正在评估参数this.userId
而不是this._id
?
我认为您需要更改此:
'deals.insert'(_id, title, description, category, price, location) {
if (!this.userId) {
throw new Meteor.Error('not-allowed');
}
...
对此:
'deals.insert'(_id, title, description, category, price, location) {
if (!this._id) {
throw new Meteor.Error('not-allowed');
}
