javascript - How to nest Sequelize associations? -

-

i trying nest associations using node/sequelize/postgresql. common scenario (i believe), have yet determine how it. here scenario.

person
-- location (1:m)
----- sublocation (1:m)

the person model has belongstomany association working great. have personlocation table holds ids of both person , location , location(s) returned person query.

here's gets tricky. need associate personlocation sublocation needs 1:m relationship.

person.belongstomany(location, {through: 'personlocation'});

--this how envision work, since defined personlocation association, cannot access way.

personlocation.belongstomany(sublocation, {through: 'personlocationsublocation'});

the person have 1:m locations, each of locations have multiple 1:m sublocations. when doing query on person, want see person/locations/sublocations person.

the database

person
id
name

location
id
name

sublocation
id
name

personlocation
id
personid
locationid

personlocationsublocation
id
personlocationid
sublocationid

any ideas how achieve using sequelize?
