Python 在炼金术中使用子资源

我正试图用eve sqlalchemy构建一个RESTful API。 我想使用公共模式，在那里我可以访问资源 因此：

127.0.0.1:5000/resource1/
127.0.0.1:5000/resource1/2
127.0.0.1:5000/resource1/2/resource2
127.0.0.1:5000/resource1/2/resource2/4
127.0.0.1:5000/resource2/
127.0.0.1:5000/resource2/4

其中

resource1

和

resource2

处于父子连接中。 我检查了海军学员的问题：但是如果我在

resource2

中使用“url”配置，则无法使用原始

127.0.0.1:5000/resource2/4

和

127.0.0.1:5000/resource2

如果我为

resource2

定义了一个额外的端点，并在那里使用“url”配置，那么同样的情况也会发生，我无法以普通方式访问

resource2

。 有没有办法达到预期效果，还是我做错了什么

源代码：

models.py：

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column, String, Integer, DECIMAL, DATETIME, ForeignKey
from sqlalchemy.orm import relationship


Base = declarative_base()

class CommonColumbs(Base):
    __abstract__ = True
    ID = Column(Integer, primary_key=True)
    CreatedAt = Column(DATETIME)
    CreatedBy = Column(String)
    LastModifiedAt = Column(DATETIME, nullable=True)
    LastModifiedBy = Column(String)
    Etag = Column(String)

class MeasurementUnitTypes(CommonColumbs):
    __tablename__ = 'MeasurementUnitTypes'
    Name = Column(String)
    IsValid = Column(Integer)
    IsSpecial = Column(Integer)
    BaseUnitID = Column(Integer, ForeignKey('api.MeasurementUnits.ID'))
    BaseUnit = relationship("MeasurementUnits", foreign_keys=[BaseUnitID])
    __table_args__ = {"schema": "api"}

class MeasurementUnits(CommonColumbs):
    __tablename__ = 'MeasurementUnits'
    Name = Column(String)
    ConvertValue = Column(DECIMAL(asdecimal=False))
    CodeToBase = Column(String)
    CodeFromBase = Column(String)
    MeasurementUnitTypeID = Column(Integer, ForeignKey('api.MeasurementUnitTypes.ID'))
    MeasurementUnitType = relationship("MeasurementUnitTypes", foreign_keys=[MeasurementUnitTypeID])
    IsValid = Column(Integer)
    __table_args__ = {"schema": "api"}
