}
},
但是我没有得到旅行和mastertrip之间的关系。任何人都能解释一下吗?

有几件事可能是问题所在。以下是我想到的:
/masterTrip/1/trips
进行GET时实际上可能会得到数据吗?是吗?如果是这样,那听起来就像是正确的行为。 我自己对LoopBack还是比较新的,但我不确定filter[include]=belongsToRelationName
是获取所需数据的正确方法。从技术上讲,您只是在寻找hasMany数据的相关数组,对吧?在这种情况下,属于 masterTrip 的行程。获得它的RESTful方法是masterTrip/{id}/trips
希望其中一个有所帮助。

您的“属于”关系名称不是单数。它应该是单数。
当你制作“属于”时,关系名称是单数的,并且hasMany你的关系名称是复数。有关更多详细信息,请参阅官方文档 -
