反应表单内的 HandleSubimt 上未发生验证

如何解决反应表单内的 HandleSubimt 上未发生验证

如前所述，我有一些需要验证的字段，但它并没有在 react-form 上发生。我正在学习“Modern React with Redux”课程，我有以下代码，其中包含必须针对空值进行验证的 redux 表单：

import React from "react";
import {Field,reduxForm} from 'redux-form';

class StreamCreate extends React.Component {
    renderInput({input,label,Meta}){
        console.log(Meta)
        return (
            <div className="field">
                <label>{label}</label>
                <input {...input}/>
            </div>
        )
    }

    onSubmit(formValues){
        console.log(formValues);
    }
    
    render(){
        return(
            <form onSubmit={this.props.handleSubmit(this.onSubmit)} className="ui form">
                <Field name="title" component={this.renderInput} 
                    label="enter title"
                />
                <Field name="description" component={this.renderInput} 
                    label="enter description"
                />
                <button className="ui button primary">Submit</button>
            </form>
        )
    }
} 

const validate = (formValues) => { // This is not running!
    const errors = {};

    if (!formValues.title){
        errors.title = "you must enter a title";
    }
    if (!formValues.description){
        errors.description = "you must enter a description";
    }
}

export default reduxForm({
    form: 'streamCreate',validate // I followed the example to the T and checked the documentation
})(StreamCreate);
