Allow Relationship in list and detail columns

[aminalaee]

Now Relationships can be used in list or detail columns:

class User(Base):
    __tablename__ = "users"

    id = Column(Integer, primary_key=True)
    name = Column(String)
    email = Column(String)
    birthdate = Column(Date)

    addresses = relationship("Address", back_populates="user")


class Address(Base):
    __tablename__ = "addresses"

    id = Column(Integer, primary_key=True)
    user_id = Column(Integer, ForeignKey("users.id"))

    user = relationship("User", back_populates="addresses")


class UserAdmin(ModelAdmin, model=User):
    column_list = [User.id, User.name, User.email, User.addresses]


class AddressAdmin(ModelAdmin, model=Address):
    column_list = [Address.id, Address.user]
    name_plural = "Addresses"

Before this User.addresses and Address.user would not work with SQLAdmin.
