[英]Formik & yup form validation not working as expected with VirtualizedSelect
[英]Formik + Yup form string validation not working with either Material UI TextField +useFormik or Formik component
我已經使用不同的方法創建了幾個不同版本的 Formik 表單,以嘗試使錯誤處理正常工作(具體來說,如果這些輸入不是字符串,則拒絕某些字段中的輸入)。 努力了解為什么未拾取非字符串並引發錯誤...
這是我的第一次嘗試,它使用 Material UI TextField + useFormik
import { useFormik } from 'formik';
import * as yup from 'yup';
import Button from '@material-ui/core/Button';
import TextField from '@material-ui/core/TextField';
import { IAssetDTO } from '../types/types';
const validationSchema = yup.object({
id: yup
.string()
.min(1, "Please enter id more than 1 character")
.required("This field is required"),
name: yup
.string()
.min(1, "Please enter name more than 1 character")
.required("This field is required"),
tags: yup
.array()
.nullable(),
type: yup
.string()
.min(1, "Please enter name more than 1 character")
.required("This field is required"),
s3URL: yup
.string()
.min(1, "Please enter name more than 1 character")
.required("This field is required"),
thumbnailImageURL: yup
.string()
.min(1, "Please enter name more than 1 character")
.required("This field is required"),
});
//create your own upload component
export const EditAssetForm = (props:IAssetDTO) => {
const formik = useFormik({
initialValues: {
id: props.id,
name: props.name,
tags: props.tags,
type: props.type,
s3URL: props.s3URL,
thumbnailImageURL: props.thumbnailImageURL,
createdAt:props.createdAt,
updatedAt:props.createdAt
},
validationSchema: validationSchema,
onSubmit: (values) => {
console.log("logging values" +JSON.stringify(values))
alert(JSON.stringify(values, null, 2));
},
});
return (
<div>
<form onSubmit={formik.handleSubmit}>
<TextField
fullWidth
id="id"
name="id"
label="ID"
value={formik.values.id}
onChange={formik.handleChange}
error={formik.touched.id && Boolean(formik.errors.id)}
helperText={formik.touched.id && formik.errors.id}
/>...
一切都很好,並且為最小字符拋出正確的錯誤,並且是必需的。 但是如果我輸入一個字符串,不會拋出任何錯誤。
這是我的第二次嘗試,我將組件更改為使用具有模式驗證的 Formik、Form 和 Field
import { Formik, Form, Field } from 'formik';
import * as Yup from 'yup';
import { IAssetDTO } from '../types/types';
const ValidationSchema = Yup.object().shape({
id: Yup
.string()
.min(25, "Please enter id more than 25 character")
.required("This field is required"),
name: Yup
.string()
.min(1, "Please enter name more than 1 character")
.required("This field is required"),
tags: Yup
.array()
.nullable(),
type: Yup
.string()
.min(1, "Please enter name more than 1 character")
.required("This field is required"),
s3URL: Yup
.string()
.min(1, "Please enter name more than 1 character")
.required("This field is required"),
thumbnailImageURL: Yup
.string()
.min(1, "Please enter name more than 1 character")
.required("This field is required"),
});
export const NewEditAssetForm = (props:IAssetDTO) => (
<div>
<h1>Signup</h1>
<Formik
initialValues={{
id: props.id,
name: props.name,
tags: props.tags,
type: props.type,
s3URL: props.s3URL,
thumbnailImageURL: props.thumbnailImageURL,
createdAt:props.createdAt,
updatedAt:props.createdAt
}}
validationSchema={ValidationSchema}
onSubmit={values => {
console.log("logging values" +JSON.stringify(values))
alert(JSON.stringify(values, null, 2));
}}
>
{({ errors, touched }) => (
<Form>
<Field name="id" />
{errors.id && touched.id ? (
<div>{errors.id}</div>
) : null}...
當輸入值不是字符串時(例如,當我輸入數字時)仍然不會拋出任何錯誤。
我雖然可能是因為我正在將道具傳遞給表格? 所以我把道具拿出來了。
我最后一次嘗試使用了驗證模式示例的精確復制和粘貼,並且在輸入數字時沒有拋出錯誤。
我錯過了什么簡單的事情?
謝謝
對於來自 Yup 的任何字符串驗證,它們接受字母數字值。 如果你只想要字母(例如名字),你會想要探索正則表達式。
