javascript - 如何修复 : Warning: Functions are not valid as a React child

Question

我已经更新我的路由器以采用第二条主要路线。

import React from 'react';
import { Router, Route, IndexRoute, browserHistory } from 'react-router';

// Containers & Pages
// Home
import HomePage from '/imports/ui/pages/home/HomePage.js';

// Accounts
import SignUp from '/imports/ui/pages/accounts/SignUp.js';
import Login from '/imports/ui/pages/accounts/Login.js';
import ForgotPassword from '/imports/ui/pages/accounts/ForgotPassword.js';
import ResetPassword from '/imports/ui/pages/accounts/ResetPassword.js';
import PaymentPage from '/imports/ui/pages/accounts/PaymentPage.js';
import CouponPaymentPage from '/imports/ui/pages/accounts/CouponPaymentPage.js';
import AccountPage from '/imports/ui/pages/accounts/AccountPage.js';

// General
import AppContainer from '/imports/ui/containers/AppContainer.js';

// In App
import DashboardContainer from '/imports/ui/containers/app/DashboardContainer.js';
import AllRecipesContainer from '/imports/ui/containers/app/AllRecipesContainer.js';

// Legal
import PrivacyPage from '/imports/ui/pages/legal/PrivacyPage.js';
import TermsPage from '/imports/ui/pages/legal/TermsPage.js';
import DisclaimersPage from '/imports/ui/pages/legal/DisclaimersPage.js';

// Admin
import AdminContainer from '/imports/ui/containers/AdminContainer.js';
import UsersAdminContainer from '/imports/ui/containers/UsersAdminContainer.js';
import RecipeStatsPage from '/imports/ui/pages/admin/RecipeStatsPage.js';

// Routes
export const renderRoutes = () => (
  <Router onUpdate={() => window.scrollTo(0, 0)} history={browserHistory}>
    <Route path="/" component={AppContainer}>
      <IndexRoute name="Home" component={HomePage} />
      <Route name="Sign Up" path="/signup" component={SignUp} />
      <Route name="Log In" path="/login" component={Login} />
      <Route name="Forgot Password" path="/forgotpassword" component={ForgotPassword} />
      <Route name="Reset Password" path="/reset-password/:token" component={ResetPassword} />
      <Route name="Coupon Payment Page" path="/coupons/:code" component={CouponPaymentPage} />
      <Route name="Privacy Page" path="/privacy" component={PrivacyPage} />
      <Route name="Terms" path="/terms" component={TermsPage} />
      <Route name="Disclaimers" path="/disclaimers" component={DisclaimersPage} />
      <Route name="Payment" path="/payment" component={PaymentPage} />
      <Route name="Dashboard" path="/dashboard" component={DashboardContainer} />
      <Route name="Browse All Recipes" path="/browseall" component={AllRecipesContainer} />
      <Route name="Manage Account" path="/account" component={AccountPage} />
    </Route>
    <Route path="/manager" component={AdminContainer}>
      <IndexRoute name="manager home" component={UsersAdminContainer} />
      <Route path="/manager/recipes" component={RecipeStatsPage} />
    </Route>
  </Router>
);

当我在我的应用程序中导航到“/manager”时出现错误:

Warning: Functions are not valid as a React child. This may happen if you return a Component instead of from render. Or maybe you meant to call this function rather than return it. in Unknown (created by RouterContext) in RouterContext (created by Router) in Router

//AdminContainer.js

import { Meteor } from 'meteor/meteor';
import { withTracker } from 'meteor/react-meteor-data';
import Admin from '/imports/ui/layouts/Admin.js';

export default withTracker(() => {
  const userHandle = Meteor.subscribe('users.myData');
  const loading = !userHandle.ready();
  return {
    user: Meteor.user(),
    loading,
  };
}, Admin);

//UsersAdminContainer.js

import { Meteor } from 'meteor/meteor';
import { withTracker } from 'meteor/react-meteor-data';
import UsersAdminPage from '/imports/ui/pages/admin/UsersAdminPage.js';

export default withTracker(() => {
  const usersHandle = Meteor.subscribe('users.allUsers');
  const loading = !usersHandle.ready();
  return {
    loading,
    users: Meteor.users.find().fetch(),
  };
}, UsersAdminPage);

我已经尝试导入 UsersAdminPage 并将其用于索引路由的组件。我在 SO ( Functions are not valid as a React child. This may happen if you return a Component instead of from render ) 上看过这个答案。我没有看到我的错误任何帮助将不胜感激。

Answer 1

您对 withTracker 的调用不正确。他们应该将组件传递给 withTracker 的结果:

export default withTracker(() => {
  const userHandle = Meteor.subscribe('users.myData');
  const loading = !userHandle.ready();
  return {
    user: Meteor.user(),
    loading,
  };
})(Admin);
