[英]unable set a default value in redux-form w. react
I'm unable to set a default value of a form w/redux-form. 我无法设置w / redux-form表单的默认值。 The result I'm looking for is an editable text field to later to submit to the database.
我正在寻找的结果是一个可编辑的文本字段,以便稍后提交到数据库。 ie updating an email address.
即更新电子邮件地址。
I've tried setting a property in the form to value or defaultValue . 我已经尝试将表单中的属性设置为value或defaultValue 。 Note: I've taken repetitive code out to make this easier to read with just a "name" field.
注意:我已经重复使用了代码,只需一个“名称”字段就可以更容易阅读。
any insight is appreciated! 任何见解都表示赞赏!
import React, { Component, PropTypes } from 'react';
import { reduxForm } from 'redux-form';
export const fields = [ 'name']
//(container) page-profile.js
import React, { Component } from 'react';
import { connect } from 'react-redux';
import Profile from '../components/Profile';
class PageProfile extends Component {
render() {
return (
<Profile
userInfo = {this.props.userInfo}
/>
)
}
}
// requiring this page before rendering -- breaks page
PageProfile.propTypes = {
//userInfo: PropTypes.object.isRequired
}
function mapStateToProps(state) {
return {
userInfo : state.auth.userInfo
}
}
// injection to child
export default connect(mapStateToProps, {
})(PageProfile);
// profile.js
export default class Profile extends Component {
render() {
const { fields: {name }, resetForm, handleSubmit, submitting } = this.props
return (
<div>
<img className="image" src={this.props.userInfo.img_url}/>
<form onSubmit={handleSubmit}>
<div>
<div>
<label>name</label>
<div>
<input type="text" defaultValue={this.props.userInfo.name} placeholder="name" {...name}/>
</div>
{name.touched && name.error && <div>{name.error}</div>}
</div>
<button type="submit" disabled={submitting}>
{submitting ? <i/> : <i/>} Submit
</button>
</form>
</div>
)
}
}
Profile.propTypes = {
fields: PropTypes.object.isRequired,
handleSubmit: PropTypes.func.isRequired,
resetForm: PropTypes.func.isRequired,
submitting: PropTypes.bool.isRequired
}
export default reduxForm({
form: 'Profile',
fields,
validate
})(Profile)
You can supply initialValues
in reduxForm
's mapStateToProps: 你可以在
reduxForm
的mapStateToProps中提供initialValues
:
const mapFormToProps = {
form: 'Profile',
fields,
validate
};
const mapStateToProps = (state, ownProps) => ({
initialValues: {
name: ownProps.userInfo.name
}
});
reduxForm(
mapFormToProps,
mapStateToProps
)(Profile)
Then just bind like so: <input type="text" placeholder="name" {...name} />
. 然后像这样绑定:
<input type="text" placeholder="name" {...name} />
。
