如何在管理员中刷新列表视图

Question

我正在尝试获取列表以在成功执行自定义操作后刷新。

我在休息教程中使用了管理员的 saga

function * actionApproveSuccess () {
  yield put(showNotification('Executed'))
  yield put(push('/comments')) 
  // does not refresh, because the route does not change
  // react-redux-router also has no refresh() method, like react-router has...
}

我的另一个想法是以某种方式触发列表组件的刷新操作，但我不知道如何访问它或如何将它连接到 ACTION_SUCCESS 事件。

Answer 1

无法通过 React 路由器刷新路由，那是 known problem. Admin-on-rest's List component has its own refresh mechanism，但没有提供 API。

我的建议是使用基于 admin-on-rest 的自定义 <List> 组件。如果您找到公开 refresh 操作的方法，请随时在 aor 存储库上打开 PR！

Answer 2

绝对是 hacky，但解决方法可能是：

push('/comments/1') //any path to change the current route
push('/comments') //the path to refresh, which is now a new route

我已经通过操作面板用小技巧解决了这个任务。我确定这不是正确的解决方案，但在某些情况下它可以提供帮助：

class RefreshButton extends FlatButton {
  componentDidMount() {
    if (this.props.refreshInterval) {
      this.interval = setInterval(() => {
        this.props.refresh(new Event('refresh'))
      }, this.props.refreshInterval)
    }
  }

  componentWillUnmount() {
    clearInterval(this.interval)
  }
}

const StreamActions = ({ resource, filters, displayedFilters, filterValues, basePath, showFilter, refresh }) => (
  <CardActions>
    {filters && React.cloneElement(filters, { resource, showFilter, displayedFilters, filterValues, context: 'button' }) }
    <RefreshButton primary label="Refresh streams" onClick={refresh} refreshInterval={15000} refresh={refresh} icon={<NavigationRefresh />} />
  </CardActions>
);

export default class StreamsListPage extends Component {
  render() {
    return (
      <List
        {...this.props}
        perPage={20}
        actions={<StreamActions />}
        filter={{ active: true }}
        title='Active Streams'>
        <StreamsList />
      </List>
    )
  }
}

@Danila Smirnov 上面的回答在我现在使用时显示了这条消息：

Deprecation warning: The preferred way to refresh the List view is to connect your custom button with redux and dispatch the refreshView action.

现在点击刷新按钮本身也不起作用。

这是我在我的工作中得到的调整版本。

编辑：对其进行了更多修改以使其可重复使用。

RefreshListActions.js

import React, { Component } from 'react'
import FlatButton from 'material-ui/FlatButton'
import { CardActions } from 'material-ui/Card'
import NavigationRefresh from 'material-ui/svg-icons/navigation/refresh'
import { connect } from 'react-redux'
import { REFRESH_VIEW } from 'admin-on-rest/src/actions/uiActions'
import { refreshView as refreshViewAction } from 'admin-on-rest/src/actions/uiActions'

class MyRefresh extends Component {
    componentDidMount() {
        const { refreshInterval, refreshView } = this.props
        if (refreshInterval) {
            this.interval = setInterval(() => {
                refreshView()
            }, refreshInterval)
        }
    }

    componentWillUnmount() {
        clearInterval(this.interval)
    }

    render() {
        const { label, refreshView, icon } = this.props;
        return (
            <FlatButton
                primary
                label={label}
                onClick={refreshView}
                icon={icon}
            />
        );
    }
}

const RefreshButton = connect(null, { refreshView: refreshViewAction })(MyRefresh)

const RefreshListActions = ({ resource, filters, displayedFilters, filterValues, basePath, showFilter, refreshInterval }) => (
    <CardActions>
        {filters && React.cloneElement(filters, { resource, showFilter, displayedFilters, filterValues, context: 'button' }) }
        <RefreshButton primary label="Refresh" refreshInterval={refreshInterval} icon={<NavigationRefresh />} />
    </CardActions>
);

export default RefreshListActions

在我经常刷新的列表中：

import RefreshListActions from './RefreshListActions'

export default (props) => (
    <List {...props}
        actions={<RefreshListActions refreshInterval="10000" />}
        >
        <Datagrid>
            ...
        </Datagrid>
    </List>
)

Answer 5

通过 redux 使用 refreshView 操作效果很好。

查看示例....

import { refreshView as refreshViewAction } from 'admin-on-rest';
import { connect } from 'react-redux'; 

class MyReactComponent extends Component {
  //... etc etc standard react stuff...

 doSomething() {
    // etc etc do smt then trigger refreshView like below  
    this.props.refreshView();
 }
 render() {
   return <div>etc etc your stuff</div>
 }
}

export default connect(undefined, { refreshView: refreshViewAction })(
  MyReactComponent
);

Answer 6

push 只是 AOR 的重定向，它似乎对我也不起作用。 guleryuz 发布的内容对我来说是正确的。这是我在他的例子的基础上所做的：

// Import Statement
import { refreshView as refreshViewAction } from 'admin-on-rest';

class RemoveButton extends Component {
handleClick = () => {
    const { refreshView, record, showNotification } = this.props;
    fetch(`http://localhost:33333/api/v1/batch/stage/${record.id}`, { method: 'DELETE' })
        .then(() => {
            showNotification('Removed domain from current stage');
            refreshView();
        })
        .catch((e) => {
            console.error(e);
            showNotification('Error: could not find domain');
        });
}

 render() {
    return <FlatButton secondary label="Delete" icon={<DeleteIcon />}onClick={this.handleClick} />;
 }
}

这些位也很重要：

RemoveButton.propTypes = {
record: PropTypes.object,
showNotification: PropTypes.func,
refreshView: PropTypes.func,
};

export default connect(null, {
showNotification: showNotificationAction,
refreshView: refreshViewAction,
})(RemoveButton);

所以它的工作方式是使用 AOR 的 refreshViewAction 作为道具功能。这使用底层调用为我填充数据网格，即 GET_LIST。这可能不适用于您的特定用例。如果您有任何问题，请告诉我。

解决方案对我来说就像一个魅力，我的看起来有点不同

yield put(push('/comments/-1')); // This refreshes the data
yield put(showNotification('')); // Hide error
