from wtforms import StringField, PasswordField, SubmitField
from wtforms.validators import DataRequired, EqualTo

app = Flask(__name__)

app.config["SECRET_KEY"] = "akfsakfassdkjsakdwnm"


class RegisterForm(FlaskForm):
    user_name = StringField(label=u"用戶名", validators=[DataRequired(u"用戶名不能爲空")])
    password = PasswordField(label=u"密碼", validators=[DataRequired(u"密碼不能爲空")])
    password2 = PasswordField(label=u"確認密碼", validators=[DataRequired(u"確認密碼不能爲空"), EqualTo("password", u"兩次密碼不一致")])
    submit = SubmitField(label=u"提交")


@app.route("/register")
def register():
    form = RegisterForm()
    return render_template("register.html", form=form)


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

render_template模塊：調用模板

flask_wtf模塊：表單

wtforms模塊：安裝flask_wtf時自動安裝，不用另外安裝，

StringField 字符串，

PasswordField 密碼，

SubmitField 提交操做

DataRequired模塊：驗證表單項
