五十五：WTForms表单验证之渲染模板

此功能看似强大，实则鸡肋

from wtforms import Form, StringField, BooleanField, SelectField
from wtforms.validators import Length, ValidationError

class SettingForm(Form):
    username = StringField('用户名：', validators=[Length(3, 10, message='用户名长度为3~10位')])
    tags = SelectField('标签：', choices=[('1', 'python'), ('2', 'java'), ('3', 'c')])  # 下拉选项框
    remember = BooleanField('记住我：')  # 复选框

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .username-input{
            background: red;
        }
    </style>
</head>
<body>
<form action="" method="post">
    <table>
        <tbody>
            <tr>
                <td>用户名：</td>
                <td><input type="text" name="username"></td>
            </tr>
            <tr>
                <td>{{ form.username.label }}</td>
                <td>{{ form.username(class='username-input') }}</td>
            </tr>
            <tr>
                <td>{{ form.tags.label }}</td>
                <td>{{ form.tags() }}</td>
            </tr>
            <tr>
                <td>{{ form.remember.label }}</td>
                <td>{{ form.remember() }}</td>
            </tr>
            <tr>
                <td></td>
                <td><input type="submit" value="点击提交"></td>
            </tr>
        </tbody>
    </table>
