Geçişleri çalıştırırken hata oluştu: sqlalchemy.exc.CompileError: Postgresql ENUM türünde bir adlandırma gerekiyor

Question

İlk kez yükseltmeyi çalıştırmayı denediğimde bu hataya giriyorum. Bir name niteliği vermiş olmama rağmen, gender_types enum üzerinde başarısız görünüyor.

Bunun için bir düzeltme var mı? SQL'in ne üretildiğini görmenin bir yolu var mı?

Bu benim models.py adresim ve flask.ext.migrate.upgrade'yi çalıştırdığımda aldığım hata budur.

class User(UserMixin, db.Model): 
    __tablename__ = 'users' 
    id = db.Column(db.Integer, primary_key=True) 
    first = db.Column(db.String(64)) 
    last = db.Column(db.String(64)) 
    dob = db.Column(db.Date) 
    street_addr1 = db.Column(db.String(64)) 
    street_addr2 = db.Column(db.String(64)) 
    city = db.Column(db.String(64)) 
    state = db.Column(db.String(2)) 
    zip = db.Column(db.String(9)) 
    gender = db.Column(db.Enum('M', 'F', name='gender_types')) 
    home_box = db.Column(db.String(32)) 
    username = 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) 
    def __repr__(self): 
     return '<User %r>' % self.username 

@login_manager.user_loader 
def load_user(user_id): 
    return User.query.get(int(user_id)) 

class Competition(db.Model): 
    __tablename__ = 'competitions' 
    id = db.Column(db.Integer, primary_key=True) 
    name = db.Column(db.String(12)) 

Terminal çıkışı: Bu çünkü olur derlemek bir SQLAlchemy hatası, çünkü

Sen Enum ad öznitelik eklemek gerekir
