我有两个收藏Articles
和Categories
让他们说他们的文件是这样的
文章
{
"_id": "blabla",
"title" : "title",
"description" : "description",
"categoryId" : "catId"
}
分类
{
"_id": "catId",
"title" : "category",
"description" : "description"
}
我想订阅它们就像这样
{
"_id": "blabla",
"title" : "title",
"description" : "description",
"category" : {
"title" : "category",
"description" : "description"
}
}
我尝试使用publish-composite,这是我的代码。 服务器
Meteor.publishComposite('articles', {
find: function() {
return Articles.find({}, { sort: {}, limit: 10 });
},
children: [
{
find: function(article) {
return Categories.findOne({ _id: article.categoryId });
}
}
]
});
客户端angularjs控制器
angular.module("dee").controller("ArticlesListCtrl", ['$scope', '$meteor', function($scope, $meteor){
$scope.articles = $meteor.collection(Articles).subscribe('articles');
}]);
和视图是
{{ articles | json }}
问题是它只打印文章集合而没有关系。

添加@Deadly发布的内容:
发布复合可以方便地在单个订阅中获取相关文档。如何处理这些文档仍然与您进行2次单独订阅时相同。
在您的情况下,您将有两个客户端集合。一个文章集合和一个类别集合。本地馆藏中的哪些文章和哪些类别基于您所订阅的订阅。
// get a subscription to 'articles'. Use $scope.$meteorCollection so
// the subscription is destroyed when the $scope is destroyed. If you don't you will end up carrying these collections on to anther page.
$scope.$meteorSubscribe('articles').then(function() {
// This swill get you the articles from the local collection
$scope.articles = $scope.$meteorCollection(Articles);
// then you need to get the related Categories for the articles
$scope.getCategories = function(article) {
return $scope.$meteorObject(Categoris, article._id);
}
});

控制器:
#!/bin/sh
myfunc()
{
echo kill "$@" $(jobs -p)
}
myfunc -l -L
myfunc -l
HTML:
angular.module("dee").controller("ArticlesListCtrl", ['$scope', '$meteor', function($scope, $meteor){
$scope.articles = $scope.$meteorCollection(Articles).subscribe('articles');
$scope.getCategory = function(article) {
return $scope.$meteorObject(Categories, article._id);
};
}]);
我也知道更好的方法,但它不适用于角度,看起来没有人关心它https://github.com/Urigo/angular-meteor/issues/720
