Flask_WTF实现表单

2021-10-05 11:04:10 作者：互联网

Flask_WTF实现表单可分为六个步骤：

①导入FlaskForm扩展包（from flask_wtf import FlaskForm)

②导入StringField,PasswordField,SubmitField (from wtforms import StringField,PasswordField,SubmitField)

③定义表单类

class RegisterForm(FlaskForm):
    username = StringField('账号：')
    password = PasswordField('密码：')
    password2 = PasswordField('确认密码：')
    submit=SubmitField('提交')

④定义路由

@app.route('/regist',methods=['GET','POST'])
def regist_form():
    redist_form=RegisterForm()
    return render_template('registform.html',form=redist_form)

⑤html文件中实现表单

<form method="post">
        {{ form.username.label }}{{ form.username }}<br>
        {{ form.password.label }}{{ form.password }}<br>
        {{ form.password2.label }}{{ form.password2 }}<br>
        {{ form.submit }}
    </form>

完整代码：

app.py

from flask import Flask,render_template,request,flash
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField,SubmitField

app = Flask(__name__)
app.secret_key='yingjie'

# 定义表单类
class RegisterForm(FlaskForm):
    username = StringField('账号：')
    password = PasswordField('密码：')
    password2 = PasswordField('确认密码：')
    submit=SubmitField('提交')

@app.route('/regist',methods=['GET','POST'])
def regist_form():
    redist_form=RegisterForm()
    return render_template('registform.html',form=redist_form)

if __name__ == '__main__':
    app.run()

registform.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <form method="post">
        {{ form.username.label }}{{ form.username }}<br>
        {{ form.password.label }}{{ form.password }}<br>
        {{ form.password2.label }}{{ form.password2 }}<br>
        {{ form.submit }}
    </form>
</body>
</html>

运行结果：
