[英]React: TypeError: dispatch is not a function
我想從 redux 獲取。 我正在關注本教程: https://codesandbox.io/s/react-redux-application-hewdb?file=/src/pages/PostsPage.js
但是當我在我的代碼中使用它時:
import React, { useState, useEffect } from 'react';
import { connect } from 'react-redux';
import {fetchInterview} from '../actions/interviewActions'
const DetailInterview = (props, { dispatch, loading, interviews, hasErrors }) => {
console.log("test interview",interviews)
useEffect(() => {
const { match: { params: { id } } } = props;
dispatch(fetchInterview(id))
}, [dispatch])
const interviewslist = interviews
console.log('interview: ', interviews)
return (
<div>
<h3>All participants</h3>
<table>
<thead>
<tr>
<th>ID</th>
<th>Interview id</th>
<th>Partcipants id</th>
<th>Time</th>
</tr>
</thead>
<tbody>
{
console.log('interviews:sad ', interviews)
}
{
interviews? interviews.map((interview) => {
console.log('sadassad',interview)
console.log('sadaghahhgsghssad',interviews)
return (
<tr key={interview.id}>
<td>{interview.id}</td>
<td>{interview.interview_id}</td>
<td>
{/* <Link to={`/posts/${post.id}`}> */}
{interview.participant_id}
{/* </Link> */}
</td>
<td>{interview.created_at}</td>
</tr>
)
}) : null
}
</tbody>
</table>
</div>
);
}
// export default DetailInterview;
const mapStateToProps = state => ({
loading: state.interview.loading,
interviews: state.interview.interview,
hasErrors: state.interview.hasErrors,
})
export default connect(mapStateToProps)(DetailInterview)
我收到一個錯誤:未捕獲的類型錯誤:調度不是 function
無法理解這背后的錯誤是什么。
您正在從 DetailInterview 的第二個參數中解構值,而您應該從道具中執行此操作,因為 mapStateToProps 中的值和 connect 可用作連接組件的道具
const DetailInterview = (props) => {
const { dispatch, loading, interviews, hasErrors } = props;
...
}
