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

const required = value => (value || typeof value === 'number' ? undefined : 'Required')
const maxLength = max => value =>
  value && value.length > max ? `Must be ${max} characters or less` : undefined
const maxLength15 = maxLength(15)
export const minLength = min => value =>
  value && value.length < min ? `Must be ${min} characters or more` : undefined
export const minLength2 = minLength(2)
const number = value =>
  value && isNaN(Number(value)) ? 'Must be a number' : undefined
const minValue = min => value =>
  value && value < min ? `Must be at least ${min}` : undefined
const minValue13 = minValue(13)

const FieldLevelValidationForm = props => {
  const { handleSubmit, pristine, reset, submitting } = props
  return (
    <form onSubmit={handleSubmit}>
      <Field
        name="username"
        type="text"
        component={renderField}
