Javascript Ember.js：访问父路由'；s控制器

我的应用程序中的用户有个人资料页面。用户可以查看自己的个人资料和其他用户的个人资料。在他自己的个人资料中，他可以更改他的头像，但当然他不能更改其他用户的头像。使用配置文件路径的beforeModelhook，根据需要加载用于上传化身的脚本。问题是，仅当用户访问自己的配置文件而不是其他用户的配置文件时，才加载此脚本

这是我的密码：

路由器：

Router.map(function () {

    this.resource('user', { path: '/:user_id' }, function () {
        this.resource('profile');
    });

});

var ApplicationRoute = Em.Route.extend({

    model: function () {
        return {
            currentUser: this.config.currentUser
        };
    }

});

var UserRoute = Em.Route.extend({

    model: function (params) {
        var currentUser = this.modelFor('application').get('currentUser');

        if (currentUser.get('id') === params.user_id) {
            return currentUser;
        } else {
            // getUser returns promise
            return this.data.getUser(params.user_id);
        }
    }

});

var UserController = Em.ObjectController.extend({

    needs: 'application',

    isCurrent: function () {
        return (this.get('id') === this.get('controllers.application.currentUser.id'));
    }.property('id')

});

var uploaderScriptInjected = false;

var ProfileRoute = Em.Route.extend({

    beforeModel: function () {
        if (!uploaderScriptInjected && this.uploaderNeeded()) {
            return $.getScript(this.config.assets.uploader)
                .then(function () {
                    uploaderScriptInjected = true;
                });
        }
    },

    uploaderNeeded: function () {
        // This is not working:

        // return this.controllerFor('user').get('isCurrent');
    },

    model: function () {
        var user = this.modelFor('user');

        return Em.RSVP.hash({
            photos: this.data.photosByUser(user.get('id'))
        });
    }

});

申请途径：

Router.map(function () {

    this.resource('user', { path: '/:user_id' }, function () {
        this.resource('profile');
    });

});

var ApplicationRoute = Em.Route.extend({

    model: function () {
        return {
            currentUser: this.config.currentUser
        };
    }

});

var UserRoute = Em.Route.extend({

    model: function (params) {
        var currentUser = this.modelFor('application').get('currentUser');

        if (currentUser.get('id') === params.user_id) {
            return currentUser;
        } else {
            // getUser returns promise
            return this.data.getUser(params.user_id);
        }
    }

});

var UserController = Em.ObjectController.extend({

    needs: 'application',

    isCurrent: function () {
        return (this.get('id') === this.get('controllers.application.currentUser.id'));
    }.property('id')

});

var uploaderScriptInjected = false;

var ProfileRoute = Em.Route.extend({

    beforeModel: function () {
        if (!uploaderScriptInjected && this.uploaderNeeded()) {
            return $.getScript(this.config.assets.uploader)
                .then(function () {
                    uploaderScriptInjected = true;
                });
        }
    },

    uploaderNeeded: function () {
        // This is not working:

        // return this.controllerFor('user').get('isCurrent');
    },

    model: function () {
        var user = this.modelFor('user');

        return Em.RSVP.hash({
            photos: this.data.photosByUser(user.get('id'))
        });
    }

});

用户路线：

Router.map(function () {

    this.resource('user', { path: '/:user_id' }, function () {
        this.resource('profile');
    });

});

var ApplicationRoute = Em.Route.extend({

    model: function () {
        return {
            currentUser: this.config.currentUser
        };
    }

});

var UserRoute = Em.Route.extend({

    model: function (params) {
        var currentUser = this.modelFor('application').get('currentUser');

        if (currentUser.get('id') === params.user_id) {
            return currentUser;
        } else {
            // getUser returns promise
            return this.data.getUser(params.user_id);
        }
    }

});

var UserController = Em.ObjectController.extend({

    needs: 'application',

    isCurrent: function () {
        return (this.get('id') === this.get('controllers.application.currentUser.id'));
    }.property('id')

});

var uploaderScriptInjected = false;

var ProfileRoute = Em.Route.extend({

    beforeModel: function () {
        if (!uploaderScriptInjected && this.uploaderNeeded()) {
            return $.getScript(this.config.assets.uploader)
                .then(function () {
                    uploaderScriptInjected = true;
                });
        }
    },

    uploaderNeeded: function () {
        // This is not working:

        // return this.controllerFor('user').get('isCurrent');
    },

    model: function () {
        var user = this.modelFor('user');

        return Em.RSVP.hash({
            photos: this.data.photosByUser(user.get('id'))
        });
    }

});

用户控制器：

Router.map(function () {

    this.resource('user', { path: '/:user_id' }, function () {
        this.resource('profile');
    });

});

var ApplicationRoute = Em.Route.extend({

    model: function () {
        return {
            currentUser: this.config.currentUser
        };
    }

});

var UserRoute = Em.Route.extend({

    model: function (params) {
        var currentUser = this.modelFor('application').get('currentUser');

        if (currentUser.get('id') === params.user_id) {
            return currentUser;
        } else {
            // getUser returns promise
            return this.data.getUser(params.user_id);
        }
    }

});

var UserController = Em.ObjectController.extend({

    needs: 'application',

    isCurrent: function () {
        return (this.get('id') === this.get('controllers.application.currentUser.id'));
    }.property('id')

});

var uploaderScriptInjected = false;

var ProfileRoute = Em.Route.extend({

    beforeModel: function () {
        if (!uploaderScriptInjected && this.uploaderNeeded()) {
            return $.getScript(this.config.assets.uploader)
                .then(function () {
                    uploaderScriptInjected = true;
                });
        }
    },

    uploaderNeeded: function () {
        // This is not working:

        // return this.controllerFor('user').get('isCurrent');
    },

    model: function () {
        var user = this.modelFor('user');

        return Em.RSVP.hash({
            photos: this.data.photosByUser(user.get('id'))
        });
    }

});

配置文件路径：

Router.map(function () {

    this.resource('user', { path: '/:user_id' }, function () {
        this.resource('profile');
    });

});

var ApplicationRoute = Em.Route.extend({

    model: function () {
        return {
            currentUser: this.config.currentUser
        };
    }

});

var UserRoute = Em.Route.extend({

    model: function (params) {
        var currentUser = this.modelFor('application').get('currentUser');

        if (currentUser.get('id') === params.user_id) {
            return currentUser;
        } else {
            // getUser returns promise
            return this.data.getUser(params.user_id);
        }
    }

});

var UserController = Em.ObjectController.extend({

    needs: 'application',

    isCurrent: function () {
        return (this.get('id') === this.get('controllers.application.currentUser.id'));
    }.property('id')

});

var uploaderScriptInjected = false;

var ProfileRoute = Em.Route.extend({

    beforeModel: function () {
        if (!uploaderScriptInjected && this.uploaderNeeded()) {
            return $.getScript(this.config.assets.uploader)
                .then(function () {
                    uploaderScriptInjected = true;
                });
        }
    },

    uploaderNeeded: function () {
        // This is not working:

        // return this.controllerFor('user').get('isCurrent');
    },

    model: function () {
        var user = this.modelFor('user');

        return Em.RSVP.hash({
            photos: this.data.photosByUser(user.get('id'))
        });
    }

});

查看配置文件路由的

beforeModel

和

uploadereded

方法。我想使用user controller的

isCurrent

属性，但是

setupController

方法在

uploadereded

之后被调用，这意味着还没有生成user controller的实例，也没有设置它的模型。当然，我可以使用以下代码：

uploaderNeeded: function () {
    return this.modelFor('application').get('currentUser.id') === this.modelFor('user').get('id');
}

…但它重复用户控制器的

isCurrent

属性逻辑

---

是否有任何方法可以从配置文件路由的方法访问用户控制器的属性？

例如，尝试扩展父控制器

App.FirstController=Ember.ArrayController.extend（{}）

然后

---

App.SecondController=Ember.FirstController.extend（{}）

也许我遗漏了一些东西，但它如何帮助我呢？你可以制作扩展UserController的概要文件控制器。。这一定行得通，但我不确定
