如何使用Backbone.js將參數傳遞給控制器​​？

Question

在我Backbone.js的景色之一，我有以下代碼：

events: 
    'click .filter_classroom_size': 'filterClassroom' 

    filterClassroom: (event)-> 
    event.stopPropagation() 
    event.preventDefault() 
    Backbone.history.navigate("classrooms?nationality", true) 

我的路由器具有下面的代碼：

routes: 
    'classrooms?:filter': 'classrooms' 

    initialize: -> 
    @collection = new Classrooms.Collections.Entries() 
    @collection.fetch() 

    classrooms: (filter) -> 
    classroomView = new Seats.Views.ClassroomIndex(collection: @collection) 
    $('#output_container').html(classroomView.render().el) 
    alert("#{filter}") # this prints out the filter parameter 

classrooms_controller.rb：

class ClassroomsController < ApiController 
    def show 
    # How do I send a parameter here so I can filter on it? 
    respond_with Classroom.all 
    end 
end 

我想能夠將參數傳遞到控制器，以便我可以過濾數據庫結果。

謝謝！

骨幹網使用jQuery.ajax引擎蓋下，所以你可以簡單地通過內部方法，如save，fetch和destroy jQuery.ajax選項。

initialize: -> 
    @collection = new Classrooms.Collections.Entries() 
    @collection.fetch 
    data: 
     your_key: your_value
