coffeescript - Implementing a simple search with Meteor and Iron Router -

in next phase of meteor journey (read: learning ropes!), i'd implement simple search based on user inputed values, redirect route specific record returned server.

at moment, i'm picking inputed values via code:

template.home.events 'submit form': (event, template) ->   event.preventdefault()   console.log 'form submitted!'   countryfirst = event.target.firstcountrysearch.value   countrysecond = event.target.secondcountrysearch.value   session.set 'countrypairsearchinputs', [countryfirst, countrysecond]   countrypairsearchinputs = session.get 'countrypairsearchinputs'   console.log(countrypairsearchinputs)   return router.go('explore') 

happily, console log returns desired countrypairsearchinputs variable - array of 2 ids. in routes.coffee file have following:

@route "explore",     path: "/explore/:_id"     waiton: ->       meteor.subscribe 'countrypairssearch' 

on server side, have:

meteor.publish 'countrypairssearch', getcountrypairssearch 

and finally, have search.coffee file in /lib directory defines getcountrypairssearch function:

@getcountrypairssearch = ->   countrypairs.findone $and: [     { country_a_id: $in: session.get('countrypairsearchinputs') }     { country_b_id: $in: session.get('countrypairsearchinputs') }   ] 

with regards search function itself, have countrypairs collection each record has 2 ids (country_a_id , country_b_id) - aim here allow users input 2 countries, corresponding countrypair being returning.

i'm struggling tie pieces - console output on searching currently:

uncaught error: missing required parameters on path "/explore/:_id". missing params are: ["_id"]. params object passed in was: undefined. 

any appreciated - can tell i'm new meteor , still getting used pub/sub methodology!

edited: mixed client/server publish method when first posted - danger of late-night posting!

first, seems you're expecting :id parameter on 'explore' route.

if understand you're case, you're not expecting params here, can delete ':id' route:

@route "explore", path: "/explore/" waiton: ->   meteor.subscribe 'countrypairssearch' 

or either add params router.go call:

router.go('explore', {_id: youridvar}); 

secondly, you're trying use client function: session.get() server-side. try update publication using parameter ; or using method.call.

client-side

meteor.subscribe 'countrypairssearch' countrya countryb 

not sure coffeescript syntax, check http://docs.meteor.com/#/full/meteor_subscribe

and server-side

@getcountrypairssearch = (countrya, countryb) ->   countrypairs.findone $and: [     { country_a_id: $in: countrya }     { country_b_id: $in: countryb }   ]
