我正在尝试按照Backbone Rails教程进行操作,并且试图在CompositeView中渲染我的链接集合时遇到困难,不涉及嵌套。我怀疑教程已经过时,但由于我还缺乏Backbone技能,我无法指出问题。请看下面的代码:
创建导航链接集合。
@TestApp.module "Entities", (Entities, App, Backbone, Marionette, $, _) ->
class Entities.Navigation extends Backbone.Model
class Entities.NavigationCollection extends Backbone.Collection
model: Entities.Navigation
API =
getLinks: ->
new Entities.NavigationCollection [
{ name: "one" }
{ name: "two" }
{ name: "three" }
{ name: "four" }
{ name: "five" }
]
App.reqres.setHandler "navigation:entities", ->
API.getLinks()
核心导航文件。
@TestApp.module "NavigationUnit", (NavigationUnit, App, Backbone, Marionette, $, _) ->
@startWithParent = false
API =
listNavigation: ->
NavigationUnit.List.Controller.listNavigation()
NavigationUnit.on "start", ->
API.listNavigation()
控制器,我将集合传递给视图。
@TestApp.module "NavigationUnit.List", (List, App, Backbone, Marionette, $, _) ->
List.Controller =
listNavigation: ->
links = App.request "navigation:entities"
navigationView = @getNavigationView links
App.navRegion.show navigationView
getNavigationView: (links) ->
new List.Navigation
collection: links
观点。
@TestApp.module "NavigationUnit.List", (List, App, Backbone, Marionette, $, _) ->
class List.NavigationLinks extends Marionette.ItemView
template: "navigation/list/templates/_links"
tagName: "li"
class List.Navigation extends Marionette.CompositeView
template: "navigation/list/templates/list_navigation"
itemView: List.NavigationLinks
itemViewContainer: "ul"
ItemView模板的内容为%a{:href => "#"}= @name
。在CompositeView中是一个带有%ul
标记的基本包装结构。现在发生的是CompositeView按预期呈现模板,但它不会使用itemView填充%ul
。相反,它创建的div数量等于集合中的模型数量(在本例中为5)并插入整个包装模板,所以看起来像这样:
#navRegion
.div
.navigation-wrapper
.navigation-content
%ul
.div
.navigation-wrapper
// entire template
.div
.navigation-wrapper
// entire template
//etc +3 divs
我在这里做错了什么?

您的教程可能已过期。 Marionette在版本2.0.0中将该属性从itemView
重命名为childView
。
来自the docs
每个childView都将使用childView的模板进行渲染。 CompositeView' s 渲染模板,并将childView的模板添加到此。
var ChildView = Marionette.ItemView.extend({});
var CompView = Marionette.CompositeView.extend({
childView: ChildView
});
