我正在使用 react-redux 构建一个应用程序并且有 3 个主要问题。在一个 volenteer 组件中,我从 store 中获取 volenteers 的数据,然后通过将数据和列(作为常量导入)传递给它在表组件中显示它。
志愿者组件:
import React, {Component} from 'react';
import { connect } from 'react-redux';
import { requestVolunteerData } from '../actions';
import { volenteerColumns as columns } from '../utils/constants';
import '../container/App.css';
import Table from '../components/Table/Table';
import Loading from '../components/Loading/Loading';
import {Link} from 'react-router-dom';
const mapStateToProps = state => {
return {
entities: state.requestEntitiesReducer.entities,
isPending: state.requestEntitiesReducer.isPending,
error: state.requestEntitiesReducer.error
}
}
const mapDispatchToProps = dispatch => {
return {
onRequestEntities: () => dispatch(requestVolunteerData())
}
}
class Volenteer extends Component{
componentDidMount () {
this.props.onRequestEntities();
}
render () {
const { entities, isPending} = this.props;
return isPending ?
<Loading />
:
(
<div className='tc'>
<h1 className='f1'>רשימת מתנדבים</h1>
<Table data={ entities } columns={ columns }/>
</div>
);
}
}
export default connect(mapStateToProps, mapDispatchToProps)(Volenteer);
常量文件 - 包含 volenteerColumns :
import {Link} from 'react-router-dom';
// Types
export const REQUEST_ENTITIES_PENDING = 'REQUEST_ENTITIES_PENDING';
export const REQUEST_ENTITIES_SUCCES = 'REQUEST_ENTITIES_SUCCES';
export const REQUEST_ENTITIES_FAILED = 'REQUEST_ENTITIES_FAILED';
// Columns
export const volenteerColumns = [{
dataField: 'name',
text: 'שם פרטי'
}, {
dataField: 'name',
text: 'שם משפחה'
}, {
dataField: 'phone',
text: 'עיר'
},{
dataField: 'yeshuv',
text: 'כתובת'
},{
dataField: 'phone',
text: 'מספר טלפון'
},{
dataField: 'area',
text: 'איזור פעילות מועדף'
},{
dataField: 'occupation',
text: 'תחום עיסוק'
}, {
dataField: 'alertDonationInArea',
text: 'התראה על תרומה באיזור'
}, {
dataField: 'alertdonationNearBy',
text: 'התראה על תרומה קרובה'
}, {
dataField: 'status',
text: 'סטטוס'
}, {
dataField: 'bDate',
text: 'תאריך יום הולדת'
}, {
dataField: "_id",
text: "פעולות",
formatter: (rowContent, row) => {
return (
<Link to={`/volenteerRoute/${_id}`}>
<button className='btn btn-outline-primary btn lg'>view</button>
</Link>
)
}
}];
它看起来像这样:
我想要的是,当我单击查看按钮时,它将转到一条新路线:<Route path='/volenteerRoute/:id' component={VolenteerDetails} />
并将显示此特定志愿者的数据。我的问题是:
现在,如果可能的话,我想从外部文件中导入 volenteer 列(出于可读性原因和短代码),这不是真正的常量......因为按钮应该指向动态路线,所以我如何通过单击更改我的路线查看按钮?我知道我写得不正确(如何使用格式化程序)-通过在外部文件中找到的那个按钮来传递志愿者 ID 的正确方法是什么?
将 volenteer 的状态传递给 的正确方法是什么
<Route path='/volenteerRoute/:id' component={VolenteerDetails} />
,是通过这样的链接:<Link to ={{pathname: "/volenteerRoute/:id", state: { volenteerDetails: this.state.volenteerDetails}}} >
还是通过另一个 fetch API 调用的 redux 操作(首选)?如果是这样,我如何获取这些数据?这些是我的行动:
//volunteer
export const requestVolunteerData = () => getData('http://localhost:8000/api/volunteer');
export const requestOneVolunteerData = () => getData('http://localhost:8000/api/volunteer/:id');
调用 getData 函数:
import {
REQUEST_ENTITIES_PENDING,
REQUEST_ENTITIES_SUCCES,
REQUEST_ENTITIES_FAILED
} from './constants';
export const getData = (url) => (dispatch) => {
dispatch ( {type: REQUEST_ENTITIES_PENDING} );
fetch(url)
.then ( response => response.json() )
.then( resp => dispatch({type: REQUEST_ENTITIES_SUCCES, payload: resp.data }) )
.catch(error => dispatch({type: REQUEST_ENTITIES_FAILED, payload: error}) )
}
但当然第二个动作不起作用,因为我不知道如何将 ID 从视图按钮传递给该动作
VolenteerDetails(应该显示特定志愿者详细信息的组件)如何获取数据?是靠道具吗?
const VolenteerDetails = ({ props}) => { console.log(props); return ( <div> <h2>volenteer details </h2> </div> ) }
抱歉这个问题的长度,感谢您的帮助!
