withFormik : On initial value change, update props.value
提问by Abel Jojo
Once the initial props changes, the values in the forms need to be updated
一旦初始 props 发生变化，表单中的值需要更新
export default withFormik({
mapPropsToValues: (props: Props) => {
return (
{
id: props.initialData.id,
name: props.initialData.name
}
);
},
handleSubmit: (values, { props: Props, setSubmitting }) => {
Props.submitHandler(values);
},
})(NewDatasourceForm);
Here in mapPropsToValuesI am able to get the new props, But the values in form not get updated.
在这里，mapPropsToValues我能够获得新的props，但表单中的值没有得到更新。
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) => {
Add enableReinitialize: true,solved the issue
