loopbackjs - HasAndBelongsToMany symmetric query -


i trying figure out how use hasandbelongstomany relation simple case. example have 2 models, person (derived user) , someobject (derived persistentmodel).

now when add relation someobject -> hasandbelongstomany -> person (let call rela) can example do

put /someobject/{id}/rela/{fk}

this creates joined model someobjectperson. cannot query someobjects given id of person.

i have looked examples , of them create relation other direction (let's call rela2) person -> hasandbelongstomany -> someobject. not understand why, since relation name suggests symmetrical nature.

but if , perform a

put /person/{id}/rela2/{fk}

another joined model created disjoint data. additionally queries in 1 direction return values added in respective direction.

i guess through-model help, far can tell whole idea of relation rid of (visible) through models consisting of (foreign) ids. not mention can't tell semantic difference between hasandbelongstomany or hasmany...

hope can enlighten me.

best, richard

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
