所以我无法弄清楚这里的错误是什么(我很确定我只是在做一些愚蠢的事情)。任何帮助,将不胜感激。这是models.py
DATABASE = SqliteDatabase('social.db')
class User(UserMixin, Model):
username = CharField(unique=True)
email = CharField(unique=True)
password = CharField(max_length=100)
joined_at = DateTimeField(default=datetime.datetime.now)
is_admin = BooleanField(default=False)
class Meta:
database = DATABASE
order_by = ('-joined_at',)
class Post(Model):
timestamp = DateTimeField(default=datetime.datetime.now)
user = ForeignKeyField(User, related_name='posts')
content = TextField()
class Meta:
database = DATABASE
order_by = ('-timestamp',)
class Relationship(Model):
from_user = ForeignKeyField(User, related_name = 'relationships')
to_user = ForeignKeyField(User, related_name = 'related_to')
class Meta:
database = DATABASE
indexes = ((('from_user', 'to_user'), True))
我没有在课程中包含这些函数,因为我认为不需要它。我不想让代码混乱。请告诉我你是否需要它。这是错误。 (我发现了类似错误的问题,但我仍然无法弄清楚我的错误)

谢谢!
单项元组中缺少逗号:
indexes = ((('from_user', 'to_user'), True),)
