我在服务器上关注:
items.allow({
'insert': function (userId,doc) {
return true;
}
});
Meteor.methods({
getChildren: function(parentId) {
var children = items.find({parent: parentId});
console.log("children: "+children.count());
Meteor.publish(parentId, function() {
console.log("publishing to : "+parentId);
return children;
});
return true;
}
});
关于可用于服务器和客户端的collections.js ......
items = new Mongo.Collection("folders");
接下来,客户有以下内容:
Meteor.startup(function() {
items.insert({name: "HelpDocs", parent: "DocumentsA"});
items.insert({name: "Code", parent: "DocumentsA"});
items.insert({name: "Unit Tests", parent: "DocumentsA"});
});
Template.fileTree.events({
'click .mainfolders': function (e, t) {
var elemId = e.currentTarget.id;
var children = null;
Meteor.call('getChildren',elemId, function(error, result){
console.log("subscribing");
var start = new Date().getTime();
children = Meteor.subscribe(elemId, function() {
Session.set(elemId, true);
console.log("subscribed");
var end = new Date().getTime();
console.log(end - start);
});
Meteor.setTimeout(function() {
children.forEach(function(child) {
console.log("rendering");
Blaze.render(Template.fileTree, $('#'+elemId).get(0));
});
Meteor.stop(elemId);
}, 800);
});
}
});
它在children.forEach失败,但有以下异常......
[日志] setTimeout回调中的异常:http://0.0.0.0:3000/Site/client/filetree.js?83d0c4ebb8e92bb0e03e82f52ea4c0510cc0d831:21:35(meteor.js,第888行) withValue @ http://0.0.0.0:3000/packages/meteor.js?43b7958c1598803e94014f27f5f622b0bddc0aaf:955:21 http://0.0.0.0:3000/packages/meteor.js?43b7958c1598803e94014f27f5f622b0bddc0aaf:435:54 http://0.0.0.0:3000/packages/meteor.js?43b7958c1598803e94014f27f5f622b0bddc0aaf:983:27
订阅已在我设置的800毫秒超时内完成。我给光标的变量错了吗?
答案 0 :(得分:1)
Meteor.subscribe()不会返回游标。根据文档,它"返回一个提供stop()和ready()方法的句柄。"
而不是:
def index
@agendas = Agenda.all
end
您可以尝试类似(未经测试)的内容:
children = Meteor.subscribe(elemId, function() {
Session.set(elemId, true);
console.log("subscribed");
var end = new Date().getTime();
console.log(end - start);
});
