javascript - Mongo db alphabetical sorting in coffeescript -


i have collection of users, , insert them select box viewable user. wanting sort collection users name , pass on.

i grabbing roomname , returning roomname.active_users. populates select box doesn't sort them.

template.room_active_users.getactiveusers = (roomname) ->     users = rooms.findone({room_name: roomname}).active_users 

i have tried doing

users = rooms.findone({room_name: roomname}).active_users.profile.name 

but doesn't work.

currently inside collection when console.log(users):

[object, null, object]          // says there 2 users in room    0: object        _id: "ryynj48gcgd25fwhm"        profile:            avatar_url:            bio:            blog:            .            .            .            login:            name: jerry    1: null    2: object        _id: "hg4mxetjdxfdtpjje"        profile:            avatar_url:            bio:            blog:            .            .            .            login:            name: bob 

i trying find way access users' names , sort them way can't call

.active_users.profile.name 

it gives error:

exception deps recompute function: typeerror: cannot read property 'name' of undefined 

i figured have write type of sort function this, examples i've searched have turned out not work, , none specific enough fit case.

any appreciated, thanks.

you can sort , collect in database or in code. db gonna better @ sort of thing , there's not of reason pull fields when need one. if want in code, i'd use lodash's pluck:

# load users collection lodash can multiple operations chained # compact removes nulls # pluck gets key collection of objects  # value returns value chain # _(rooms.findone({room_name: roomname})).compact().pluck('name').value()  

is findone not asynch? seems should be...

it looks findone accepts projection parameter, in case you'd need pass in so:

rooms.findone({room_name: roomname}, {'name':1})
