sequelize.js - Sequelize, Many-To-Many On Non-ID Properties -


i have 1 model, target, has property/field called targetname. have second model, operation, field verb. both these models have primarykey field named id.

i have third model, policy, defined association/join additional properties; policy contains targetname , verb fields. how specify in belongstomany() target , operation use fields above, instead of defaulting id field? know of through option specify actual model. what's in ellipsis section below?

target.belongstomany(operation, {through: policy, ...}); , operation.belongstomany(target, {through: policy, ...});

also, specify 2 belongstomany()?

there no way foreign keys pointing non-primary keys in sequelize. see https://github.com/sequelize/sequelize/issues/2967
