from wtforms import Form
from wtforms.fields import simple, core
from wtforms import validators
class RegForm(Form):
username = simple.StringField(
label="用户名",
validators=[
validators.DataRequired(message="数据不能为空！"),
validators.length(min=4, max=6, message="用户名不能少于4位且不能大于6位")
],
render_kw={"class": "form-control", "pp": "88"}
)
password = simple.PasswordField(
label="密码",
validators=[
validators.DataRequired(message="密码不能为空！"),
validators.length(min=6, max=16, message="密码不能少于6位且不能大于6位"),
validators.Regexp(regex="\d+", message="密码必须是数字")
],
render_kw={"class": "form-control", "pp": "88"}
)
re_password = simple.PasswordField(
label="确认密码",
validators=[
validators.EqualTo(fieldname="password", message="两次密码不一致")
],
render_kw={"class": "form-control"}
)
gender = core.RadioField(
label="性别",
validators=[
validators.DataRequired(message="请先选择一个性别！")
],
choices=((1, "男"), (2, "女")),
coerce=int,
# default=1,

coerce=int,
default=[1, 2],
render_kw={"class": "form-control"}
)
@app.route("/register", methods=("GET", "POST"))
def reg():
form_obj = RegForm()
if request.method == "POST":
print(request.form)
form_obj = RegForm(request.form)
if form_obj.validate():
ers = request.form.to_dict()
print(ers)
print(form_obj.data)
return "注册成功"
return render_template("reg.html", form_obj=form_obj)
