创建一个通用的angularjs listController [英] Creating a generic angularjs listController

问题描述

角UI路由器可以让我解决我可以在我的控制器使用不同的注射。

Angular ui-router allows me to resolve different injections that I can use in my controllers.

我创建了一个简单的通用ListController，并在UI路由器我的模版注入包含特定该特定视图的CRUD功能的物体，沿。

I created a simple generic ListController, and in the ui-router I am injecting an object that contains the CRUD functions specific for that particular view, along with the template.

所以，举例来说，假设我有2个服务，相同的污物语法：

So, for example, let's say I have 2 services with the same "crud" syntax:

addPerson(person, callback){}
deletePerson(person, callback){}
editPerson(person, callback){}
....
addCar(car, callback){}
deleteCar(car, callback){}
editCar(car, callback){}
....

我创建了一个映射对象对这些服务的'CRUD功能映射到我的通用控制器，它是通过注射ui.router

I created a mapping object to map these services' CRUD functions into my generic controller, which is injected through the ui.router.

GenericController：

GenericController:

controller('ListCtrl', ['$scope', 'itemList', 'functions', function ($scope, itemList,   functions) {
    $scope.itemList = itemList;

    $scope.addItem = function(){
        functions.add($scope.item, callback);
    }
    .....
}

路由器：

        .state('app.people', {
            url: '/people',
            templateUrl: 'views/people.html',
            resolve: {
                    functions: ['People', function(People){
                        return {
                        add: People.createPerson,
                        update: People.updatePerson,
                        delete: People.deletePerson,
                        getItemList: People.getPeopleList
                    }
                    }],
                itemList: ['$q', 'People', function($q, People){
                var deferred = $q.defer();
                    People.getPeopleList(function(resp, status){
                        deferred.resolve(resp);
                    });
                    return deferred.promise;
                }],
                },
            controller: 'GenericController'
        })

所以，你可以通过只在其状态定义注入不同的功能映射汽车行驶使用它。

So you can use it with the cars too by just injecting a different function mapping in its state definition.

工程就像一个魅力。

但现在我想能够在专区内使用我的控制器，而不是只在一个完整的视图。现在，这里的问题：

But now I would like to be able to use my controller within a div, and not just in a full view. Now here's the problem:

如果我用的是NG-控制器指令，将喷油器不知道该怎么提供尽可能是'ITEMLIST'或'功能'（这是映射对象），但如果我初始化它通过$控制器对象，然后它不会有其自身的范围，我得到

If I use the ng-controller directive, the injector won't know what to provide as either 'itemList' or 'functions' (which is the mapping object), but if I instantiate it through the $controller object, then it won't have its own scope, and I get a

Unknown provider: $scopeProvider <- $scope

，因为它不能够创造自己的孩子..范围
我想我可以通过创建$ rootScope一个新的范围。美元的新（）或者类似的东西，但感觉太像盗号了，因为我是新来的角度，我认为这可能是像一个不错的办法这个..

because it won't be able to create its own child scope.. I guess I could create a new scope through $rootScope.$new() or something like that, but it feels too much like hacking, and since I'm new to angular, I think that this might be a bad approach for something like this..

任何提示？

推荐答案

有关备查，我结束了编写通用控制器的系统，和微小的专用控制器的扩展他们。

For future reference, I ended up writing a system of generic controllers, and tiny specialized controllers that extend them.

有关上面的例子中，通用控制器由两个把PeopleController和CarController子类。在控制器code的开始，他们每个人都会做这样的事情：

For the example above, the generic controller is subclassed by both "PeopleController" and "CarController". At the beginning of the controller code, each one of them will do something like:

controller('PeopleController', ['$scope', 'peopleService', function ($scope, peopleService) {
angular.extend(this, $controller('listController', {$scope: $scope, functions:{

        add: peopleService.addPerson,
        remove: peopleService.removePerson,
        [...]

    }}));

    $scope.people = $scope.itemList;

}

所以，现在我可以实例化自己的控制器即使在NG-控制器的指令，他们将使用通用控制器对所有的CRUD方法。

So now I can instantiate the controllers on their own even in the ng-controller directive, and they will use the generic controller for all of the CRUD methods.
