I just started doing flask restful api and trying to register a user by sending a POST request to localhost:5000/api/v1/users. The required fields are email and password. Here's the curl request to create a user curl http://localhost:5000/api/v1/users -d "email=admin@example.com&password=password" -X POST -v

But it returns me this error: AttributeError: 'UserCreateForm' object has no attribute 'password'

Below is some snip of my code

views.py

class UserView(restful.Resource):
    def post(self):
        form = UserCreateForm()
        if not form.validate_on_submit():
            return form.errors, 422

        user = User(email=form.email.data, password=form.password.data)
        db.session.add(user)
        db.session.commit()
        return UserSerializer(user).data

forms.py

BaseModelForm = model_form_factory(Form)

class ModelForm(BaseModelForm):
    @classmethod
    def get_session(self):
        return db.session

class UserCreateForm(ModelForm):
    class Meta:
        model = User

models.py ( I tired to place the UserMixin to second, still getting same error )

class User(db.Model, UserMixin):
    __tablename__ = 'users'
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(64), unique=True, index=True)
    password_hash = db.Column(db.String(128))

    @property
    def password(self):
        raise AttributeError('password is not a readable attribute')

    @password.setter
    def password(self, password):
        self.password_hash = generate_password_hash(password)

    def verify_password(self, password):
        return check_password_hash(self.password_hash, password)

Also, I have login_manager.user_loader included, so I don't think it will be issue with flask login.

And is there a documentation for wtform_alchemy? I totaly don't get how it works to create the form automatically from the models.

UserCreateForm将从您定义的列继承其字段User。User没有名为 的列password，因此UserCreateForm没有这样的字段。您必须自己添加该字段。

from wtforms.fields import PasswordField

class UserCreateForm(ModelForm):
    class Meta:
        model = User

    password = PasswordField()

WTForms -Alchemy 文档讨论了添加和覆盖字段。
