使用 Backbone.Marionette 嵌套集合 [英] Nested collections with Backbone.Marionette
问题描述
我想创建一个日历,它是一天的集合,每天都是约会的集合.day对象的结构是:
I want to create a calendar which is a day collection, and every day is a collection of appointments. The structure of day object is:
day:{
date:'08-06-2012',
appointment: {
time_begin:'12:55',
time_end: '16:40',
customer: 'Jaime'
}
}
此时我有这个模型和视图:
At this moment i have this models and views:
// CALENDAR COLLECTION
App.Calendar.Collection = Backbone.Collection.extend({
// MODEL
model: App.Day.Model
}
当日历集合从服务器获取数据时,它会获取包括约会在内的完整日对象.
When calendar collection fetch data form the server, it gets complete day objects including appointments.
// CALENDAR VIEW
App.Calendar.View = Backbone.Marionette.CompositeView.extend({
// TEMPLATE
template: Handlebars.compile(templates.find('#calendar-template').html()),
// ITEM VIEW
itemView: App.Day.View,
// ITEM VIEW CONTAINER
itemViewContainer: '#calendar-collection-block'
});
// DAY MODEL
App.Day.Model = Backbone.Collection.extend({
// PARSE
parse:function(data){
console.log(data);
return data;
}
});
// DAY VIEW
App.Day.View = Backbone.Marionette.CompositeView.extend({
collection: App.Day.Model,
itemView: App.CalendarAppointment.View, //---->I NEED TO DEFINE THIS, NOT SURE HOW
template: Handlebars.compile(templates.find('#day-template').html())
});
日模型需要是约会的集合,并且不需要从服务器获取数据,因为它每天都在里面.
The day model needs to be a collection of appointments and shouldn't be necessary to fetch data from the server because it's inside every day.
我该怎么做?
推荐答案
如果我理解正确,您是在问如何从 Day
模型中获取数据,Appointment
集合,放入CalendarApointmentView
itemView?
if I understand the question right, you're asking how to get the data from your Day
model, Appointment
collection, in to the CalendarApointmentView
itemView?
您的 Day.View
可以设置为填充此复合视图的 collection
,然后将其推送到项目视图中:
Your Day.View
can be set up to populate the collection
of this composite view, which will then be pushed in to the item views:
// DAY VIEW
App.Day.View = Backbone.Marionette.CompositeView.extend({
collection: App.Day.Model,
itemView: App.CalendarAppointment.View,
template: Handlebars.compile(templates.find('#day-template').html()),
initialize: function(){
// since `this.model` is a `Day` model, it has the data you need
this.collection = this.model.get("CalendarAppointments");
}
});
需要注意的一点:this.collection
必须是有效的 Backbone.Collection.如果您的模型将约会数据存储为一个简单的数组,那么您需要这样做:
One thing to note: the this.collection
must be a valid Backbone.Collection. If your model stores the appointment data as a simple array, then you need to do this:
var appointments = this.model.get("CalendarAppointments");
this.collection = new AppointmentCollection(appointments);
