React-admin：如何从 AppBar 隐藏刷新按钮？

Question

我正在创建基于 react-admin 的 admin ui，目前正在寻找一种解决方案来隐藏AppBar. 禁用导出按钮很简单 ( exporter={false})。RefreshButton 有什么同样简单的东西吗？我找不到任何有效的解决方案。

我的 React-admin 版本：2.9.3

我知道您可以使用List组件上的“动作”道具自定义动作，但这似乎已经过时，因为刷新按钮已移至应用栏..

AppBar如果需要，我可以将代码提供给我的自定义。

没有简单的解决方案，AppBar 中未配置 LoadingIndicator 组件的存在： https: //github.com/marmelab/react-admin/blob/master/packages/ra-ui-materialui/src/layout/AppBar。 js

您可以实现您的 AppBar 组件，然后将其连接到 AppLayout：

// Layout.js

import React from 'react';
import { Layout } from 'react-admin';
import AppBarEx from './components/AppBarEx';

const AppLayout = (props) => ( 
  <Layout
    {...props}
    appBar={AppBarEx}
  />
);

export default AppLayout;

// AppBarEx.js

import React, { Children, cloneElement } from 'react';
import PropTypes from 'prop-types';
import { connect } from 'react-redux';
import classNames from 'classnames';
import MuiAppBar from '@material-ui/core/AppBar';
import Toolbar from '@material-ui/core/Toolbar';

import MenuIcon from '@material-ui/icons/Menu';
import withWidth from '@material-ui/core/withWidth';
import compose from 'recompose/compose';
import { toggleSidebar as toggleSidebarAction } from 'ra-core';
import { UserMenu, Headroom } from 'react-admin';

const styles = theme =>
    createStyles({
        toolbar: {
            paddingRight: 24,
        },
        menuButton: {
            marginLeft: '0.5em',
            marginRight: '0.5em',
        },
        menuButtonIconClosed: {
            transition: theme.transitions.create(['transform'], {
                easing: theme.transitions.easing.sharp,
                duration: theme.transitions.duration.leavingScreen,
            }),
            transform: 'rotate(0deg)',
        },
        menuButtonIconOpen: {
            transition: theme.transitions.create(['transform'], {
                easing: theme.transitions.easing.sharp,
                duration: theme.transitions.duration.leavingScreen,
            }),
            transform: 'rotate(180deg)',
        },
        title: {
            flex: 1,
