未被捕获的TypeError：DB.find不是React with Meteor 1.3中的函数

Question

I'm using Meteor 1.3 with React and I got this error. If I use the console in the browser everything works perfectly.

 import React, {Component} from 'react'; import TrackerReact from 'meteor/ultimatejs:tracker-react'; import ToolsForm from './ToolsForm.jsx'; import ToolsCards from './ToolsCards.jsx'; export default class Tools extends TrackerReact(Component) { constructor(){ super(); this.state = { subscriptions: { tools: Meteor.subscribe('allTools') } } } componentWillUnmount() { this.state.subscriptions.tools.stop(); } tools() { return Tools.find().fetch(); } render() { return ( <div> <ToolsForm /> <br/><br/> <ul className="resolutions"> {this.tools().map( (tool)=> { return <ToolsCards key={tool._id} tool={tool} /> })} </ul> </div> ) } } 

and I got this error message:

  Uncaught TypeError: Tools.find is not a function tools @ Tools.jsx:25render @ Tools.jsx:35(anonymous function)

Tools is a React component in your code. find should be used on collections, not on React components. You'll need to define a Meteor.Collection .

See the example code here: https://github.com/ultimatejs/tracker-react
