Utenti Meteor:al momento della scrittura (versione 1.0.4.1), l'aggregazione sul client non è supportata.
Volevo mantenere il codice sul client e volevo anche la reattività, quindi ecco la mia soluzione:
db.projects
// simplified structure
{
title: 'awebsite.com'
company: 'a company'
companyID: Random.id()
category: 'website'
starred: false
tasks: [
{
completed: true
name: 'task1'
category: 'ideas'
todos: [
{todo: 'something', completed: false, todoID: Random.id()}
{todo: 'something', completed: false, todoID: Random.id()}
{todo: 'something', completed: false, todoID: Random.id()}
]
}
{
completed: false
name: 'task2'
category: 'ideas'
todos: [
{todo: 'something', completed: false, todoID: Random.id()}
{todo: 'something', completed: false, todoID: Random.id()}
{todo: 'something', completed: false, todoID: Random.id()}
]
}
]
}
../projects.coffee
Meteor.subscribe 'projects'
Tasks = new (Mongo.Collection)(null) //use (null) to create client-only collection
Template.projects.rendered = ->
results = Projects.findOne { title: 'awebsite.com' },
fields: tasks: 1
_.each results.tasks, (task) ->
Tasks.insert (task)
Template.projects.helpers
currentTask: ->
Tasks.findOne completed: false
