react-admin - 有没有办法自定义datagrid的表头？

问题描述

我正在使用 react-admin 3.8.1

并且我正在处理自定义的表头以在下面实现 - UDI Key

在此处输入图像描述

我发现的是

const MyDatagridRow = ({ record, resource, id, onToggleItem, children, selected, basePath }) => (
    <TableRow key={id}>
        {/* first column: selection checkbox */}
        <TableCell padding="none">
            <Checkbox
                disabled={record.selectable}
                checked={selected}
                onClick={() => onToggleItem(id)}
            />
        </TableCell>
        {/* data columns based on children */}
        {React.Children.map(children, field => (
            <TableCell key={`${id}-${field.props.source}`}>
                {React.cloneElement(field, {
                    record,
                    basePath,
                    resource,
                })}
            </TableCell>
        ))}
    </TableRow>
);

const MyDatagridBody = props => <DatagridBody {...props} row={<MyDatagridRow />} />;
const MyDatagrid = props => <Datagrid {...props} body={<MyDatagridBody />} />;

const PostList = props => (
    <List {...props}>
        <MyDatagrid>
            <TextField source="title" />
            ...
        </MyDatagrid>
    </List>
)

但这样我只能自定义数据网格的主体，而不是表头。

目前，唯一的方法似乎是改变 Datagrid.tsx 但我不想这样做。

如果有人知道解决方案。请让我知道，谢谢。

解决方案

React-admin<Datagrid>不提供自定义表头的方法。<Datagrid>除了使用自己的组件之外，您没有其他解决方案。

您可以将以下代码作为基础（从 react-admin 源复制，并从 TS 迁移到 JS）：

import * as React from 'react';
import {
    isValidElement,
    Children,
    cloneElement,
    useCallback,
    FC,
    ReactElement,
} from 'react';
import PropTypes from 'prop-types';
import {
    Checkbox,
    Table,
    TableProps,
    TableCell,
    TableHead,
    TableRow,
} from '@material-ui/core';
import classnames from 'classnames';

import {
    sanitizeListRestProps,
    useListContext,
    useVersion,
    DatagridHeaderCell,
    DatagridLoading,
    DatagridBody,
    useDatagridStyles
} from 'react-admin';

/**
 * The Datagrid component renders a list of records as a table.
 * It is usually used as a child of the <List> and <ReferenceManyField> components.
 *
 * Props:
 *  - rowStyle
 *
 * @example Display all posts as a datagrid
 * const postRowStyle = (record, index) => ({
 *     backgroundColor: record.nb_views >= 500 ? '#efe' : 'white',
 * });
 * export const PostList = (props) => (
 *     <List {...props}>
 *         <Datagrid rowStyle={postRowStyle}>
 *             <TextField source="id" />
 *             <TextField source="title" />
 *             <TextField source="body" />
 *             <EditButton />
 *         </Datagrid>
 *     </List>
 * );
 *
 * @example Display all the comments of the current post as a datagrid
 * <ReferenceManyField reference="comments" target="post_id">
 *     <Datagrid>
 *         <TextField source="id" />
 *         <TextField source="body" />
 *         <DateField source="created_at" />
 *         <EditButton />
 *     </Datagrid>
 * </ReferenceManyField>
