在React Admin中设置最大表单字段长度
是否有某种方法可以在a simpleform“> simpleform”>内部设置一个字段。 href =“ https://www.npmjs.com/package/reaeact-admin” rel =“ nofollow noreferrer”> react-admin 限制用户可以输入该字段的字符数量？
基于 docs ，React-Admin框架本身似乎不包含此功能。有验证当用户键入太多字符时，可以显示错误的功能，但显然显然是没有内置的方式来限制键入的字符数。鉴于此，有人是否通过其他方式实现了这一目标？
例如，假设“状态”字段的有效值仅是“ a”，“ b”或“ c”。在使用React-Admin时，如何将表单字段仅接受1个字符？
Is there some way to set a field in a SimpleForm within React-Admin to limit the number of characters a user can type into that field?
Based on the docs, the React-Admin framework itself does not appear to contain this functionality. There is validation functionality to show an error when the user types too many characters, but apparently no built-in way to limit the number of characters typed. Given this, has anyone achieved this via other means?
For example, say the valid values for a 'Status' field are only 'A', 'B' or 'C'. How, while using React-Admin, would you limit that form field to accept only 1 character?
