誰能告訴我爲什麼下面的代碼會拋出以下錯誤? :爲什麼Meteor會抱怨已經定義了一個集合的插入方法?
Error: A method named '/players/insert' is already defined
我是新來的流星CoffeeScript的,所以我可能會忽視的東西簡單。
這裏是我的排行榜例子口的CoffeeScript:
###
Set up a collection to contain player information. On the server,
it is backed by a MongoDB collection named "players."
###
Players = new Meteor.Collection("players")
if Meteor.is_client
Template.leaderboard.players = ->
Players.find({}, {sort: {score: -1, name: 1}})
Template.leaderboard.selected_name = ->
player = Players.findOne(Session.get "selected_player")
player and player.name
Template.player.selected = -> if Session.equals("selected_player", this._id) then "selected" else ''
Template.leaderboard.events = {
'click input.inc': ->
Players.update(Session.get("selected_player"), {$inc: {score: 5}})
}
Template.player.events = {
'click': ->
Session.set("selected_player", this._id)
}
# On server startup, create some players if the database is empty.
if Meteor.is_server
Meteor.startup ->
if Players.find().count() is 0
names = [
"Ada Lovelace"
"Grace Hopper"
"Marie Curie"
"Carl Friedrich Gauss"
"Nikola Tesla"
"Claude Shannon"
]
Players.insert({name: name, score: Math.floor(Math.random()*10)*5}) for name in names
完整的堆棧跟蹤如下:
[[[[[ ~/dev/meteor/leaderboard ]]]]]

throw e; // process.nextTick error, or 'error' event on first tick
