withFormik:在初始值更改时,更新props.value

Question

初始道具更改后,需要更新表单中的值

export default withFormik({
    mapPropsToValues: (props: Props) => {
        return (
            {
                id: props.initialData.id,
                name: props.initialData.name
            }
        );
    },
    handleSubmit: (values, {  props: Props, setSubmitting }) => {
      Props.submitHandler(values);
    },
  })(NewDatasourceForm);

在这里,mapPropsToValues我能够得到新的props,但形式的值不会得到更新.

```const NewDatasourceForm =(props)=> {const {values,touching,errors,isSubmitting,setFieldValue,handleSubmit,handleChange,handleBlur} = props;

const NewDatasourceForm = (props) => {
const {
    values,
    touched,
    errors,
    isSubmitting,
    setFieldValue,
    handleSubmit,
    handleChange,
    handleBlur
} = props;

const _handleSelect = (selectDSChoice) => {
    try {
        setFieldValue('dataSourceType',  selectDSChoice.value);
    } catch (error) {
        // tslint:disable-next-line:no-console
        console.error(error);
    }

};

return(
  <form className="needs-validation was-validated p-5" onSubmit={handleSubmit}>

        <div className="form-group">
            <label>Name</label>
            <input
                className={`form-control`}
                name="name"
                type="text" 
                value={values.name} 
                onChange={handleChange}
                onBlur={handleBlur}
            />
        </div>
    </form>
);
};

withFormik({
    enableReinitialize: true,
    mapPropsToValues: (props: Props) => {

添加enableReinitialize: true,解决了这个问题
