路由解析+多控制器组合? [英] Route resolving + multiple controller combo?

问题描述

我正在尝试将2个概念组合在一起，但在使它们一起工作时遇到了麻烦.

I'm trying to combine 2 concepts and I'm having trouble making them work together.

Concept 1:路由解析.这很容易解释，我只想解决以下某些模型:

Concept 1: Route resolving. This is easy to explain, I just want to resolve certain models like this:

$routeProvider
  .when("/news", {
    templateUrl: "news.html",
    controller: "newsCtrl",
    resolve: { news: function(Model) { return Model.news.getList(); }

Concept 1:我可以在路由controller: xyz中使用的基本控制器"的概念，然后在实际的html中加载"sub"控制器.例如....

Concept 1: The idea of a 'base controller' that I can use in the route controller: xyz, then in the actual view html I load the 'sub' controller. For instance....

app.js

$routeProvider
  .when("/news/latest", {
    templateUrl: "news-latest.html",
    controller: "newsCtrl"

news-latest.html

<div ng-controller="newsLatestCtrl">
...
</div>

这将使我可以将通用代码放入newsCtrl中，并将/news/latest特定代码放入newsLatestCtrl

This will allow me to put my common code inside newsCtrl, and /news/latest specific code in newsLatestCtrl

问题是我需要将这两个概念结合起来，但是很难做到，因为我不能将局部变量传递给"sub"控制器，而只能传递给主控制器.

The problem is I need to combine these two concepts, but it's hard to do that because I can't pass the local variables in to the 'sub' controller, only the main controller.

我看到的唯一选择看起来并不像是好主意...

The only options I see don't really look like good ideas...

1. 在基本控制器中，将本地变量添加为$scope变量(似乎很脏，尤其是对于大型控制器)
2. 将其移至服务中(尽管它与任何服务都没有真正的关联...)
3. ??

1. In the base controller, add the local variable as a $scope variable (seems dirty, especially for large controllers)
2. Move it into a service (it's not really relevant to any services though...)
3. ??

推荐答案

当我们不知道基本控制器"的职责是什么时，很难为您提供帮助.对我来说，您正在寻找的Concept 3如下:

It's hard to help you when we don't know what the "base controller"'s responsibilities are. For me, the Concept 3 you are looking for is as follows:

$routeProvider
.when("/news", {
templateUrl: "news.html",
controller: "newsCtrl",
resolve: { news: function(Model) { return Model.news.getList(); })
.when("/news/latest", {
templateUrl: "news.html",
controller: "newsLatestCtrl"},
resolve: { newsLatest: function(Model) { return Model.news.getLatest(); });

module.controller('newsCtrl', function($scope, news) { 
    /* common code you want to share */ 
});

module.controller('newsLatestCtrl', function($scope, newsLatest, $controller) {
   // instantiate your "base controller"
   var ctrl = $controller('newsCtrl', {
       "$scope": $scope,
       "news": newsLatest
   });
   // customize and add special code for latest news
});
