在react admin中创建自定义操作我看不到链接到我的数据提供程序的位置

我遵循本教程在React admin(rest上的前管理员)中创建自定义操作: using a custom action creator .

我的代码如下:

• UpdatePage与教程中的ApproveButton非常相似:

  // Update Page.js  
  import React, { Component } from 'react';  
  import PropTypes from 'prop-types';  
  import { connect } from 'react-redux';  
  import { updatePage } from '../../actions/pages';  
  import Button from '@material-ui/core/Button';  
  
  class UpdatePage extends Component {  
      handleClick = () => {  
          const { record } = this.props;  
          updatePage(record.id, record);  
      }  
  
      render() {
          return <Button disabled={this.props.disabled} onClick={this.handleClick}>Confirmar</Button>;
      }
  }
  
  UpdatePage.propTypes = {
      disabled: PropTypes.bool.isRequired,
      updatePage: PropTypes.func.isRequired,
      record: PropTypes.object,
  };
  
  export default connect(null, {
      updatePage
  })(UpdatePage);`
  

• //in ../../actions/pages.js  
  import { UPDATE } from 'react-admin';
  
  export const UPDATE_PAGE = 'UPDATE_PAGE';
  export const updatePage = (id, data) => ({
      type: UPDATE_PAGE,
      payload: { id, data: { ...data, is_updated: true } },
      meta: { fetch: UPDATE, resource: 'pages' },
  });
