Python 名称错误：名称'；烧瓶形式'；没有定义

您好，我是Flask和Python的新手，在没有定义FlaskForm时遇到了这个小问题 。我的烧瓶WTF版本应为：Flask-WTF-0.14.3

这是我的flaskapp.py（main）

这是我的表单。py：

from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField, BooleanField
from wtforms.validators import DataRequired, Length, Email, EqualTo

class RegistrationForm(Flaskform):
    username = StringField("Username",
                        validators=[DataRequied(), Length(ming=2, max=20)])
    email = StringFIeld("Email",
                        validators=[DataRequired(), Email()])
    password = PasswordFIeld("Password", validators=[DataRequired()])
    confirm_password = PasswordFIeld("Confirm Password",
                        validators=[DataRequired(), EqualTo("password")])
    submit = SubmitField("Sign Up")

class LoginForm(Flaskform):
    email = StringFIeld("Email",
                        validators=[DataRequired(), Email()])
    password = PasswordFIeld("Password", validators=[DataRequired()])
    remember = BooleanFIeld("Remember Me")
    submit = SubmitField("Sign Up")
   

这就是我在控制台中得到的：

class RegistrationForm(Flaskform):

NameError: name 'Flaskform' is not defined```

---

我不太清楚为什么会发生这种情况，有什么建议吗？提前感谢您抽出时间。

问题是您正在从flask\u wtf import FlaskForm导入

但是在表单中，您使用的是
Flaskform
而不是Flaskform

您的
forms.py
应该如下所示：

from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField, BooleanField
from wtforms.validators import DataRequired, Length, Email, EqualTo

class RegistrationForm(FlaskForm):
    username = StringField("Username",
                        validators=[DataRequied(), Length(ming=2, max=20)])
    email = StringFIeld("Email",
                        validators=[DataRequired(), Email()])
    password = PasswordFIeld("Password", validators=[DataRequired()])
    confirm_password = PasswordFIeld("Confirm Password",
                        validators=[DataRequired(), EqualTo("password")])
    submit = SubmitField("Sign Up")

class LoginForm(FlaskForm):
    email = StringFIeld("Email",
                        validators=[DataRequired(), Email()])
    password = PasswordFIeld("Password", validators=[DataRequired()])
    remember = BooleanFIeld("Remember Me")
    submit = SubmitField("Sign Up")

在您的类定义中，它应该是
FlaskForm
，您没有将第二个F大写，非常感谢您解决了我的错误：-）

                        validators=[DataRequired(), Email()])
    password = PasswordFIeld("Password", validators=[DataRequired()])
    confirm_password = PasswordFIeld("Confirm Password",
                        validators=[DataRequired(), EqualTo("password")])
    submit = SubmitField("Sign Up")
