Hello,
I got this error when I've tried to relate some classes:
"UnmappedClassError: Class 'zeppelinlib.user.UserTest.User' is not
mapped"
I don't get errors when I have relation many-to-many.
This is my file where I store all the User classes.
user_channels = Table(
"user_channels",
metadata,
Column("user_id", Integer, ForeignKey("users.id")),
Column("channel_id", Integer, ForeignKey(Channel.id))
)
group_permissions = Table(
"group_permissions",
metadata,
Column("group_id", Integer,
ForeignKey("user_groups.id")),
Column("permission_id", Integer,
ForeignKey(Permission.id))
)
class User(rdb.Model):
"""Represents the user"""
rdb.metadata(metadata)
rdb.tablename("users")
id = Column("id", Integer, primary_key=True)
name = Column("name", String(50))
email = Column("email", String(50))
group_id = Column("group_id", Integer, ForeignKey("user_groups.id"))
channels = relation(Channel, secondary=user_channels,
backref="channels")
class UserGroup(rdb.Model):
"""Represents a group of users with the same features"""
rdb.metadata(metadata)
rdb.tablename("user_groups")
id = Column("id", Integer, primary_key=True)
title = Column("title", String(50))
users = relation(User, backref="users")
permissions = relation(Permission, secondary=group_permissions,
backref="permissions")
How can I solve it?
Thanks in advance!
