Question

我正在django建立一个专辑应用程序，我有两个django模型

class Album(models.Model):
    name = models.CharField(max_length=100)
    family = models.ForeignKey(FamilyProfile)
    created_by = models.ForeignKey(User)
    created_date = models.DateField(default=datetime.datetime.now())

class Image(models.Model):
    album = models.ForeignKey(Album)
    name = models.CharField(max_length=100,null=True,blank=True)
    src = models.ImageField(upload_to=MEDIA_ROOT)
    upload_by = models.ForeignKey(User)
    upload_time = models.DateTimeField(default=datetime.datetime.now())

并使用tastypir for RESFull api，

在骨干中我有两个集合

   album.albumCollection = Backbone.Tastypie.Collection.extend({
        url:'/album/v1/album/',
        model:album.albumModel,
   })


   image.imageCollection = Backbone.Tastypie.Collection.extend({
       url:'/album/v1/image/',
       model:image.imageModel,
   })

和骨干路由器

album.router = Backbone.Router.extend({
    routes:{
        '':'album',
        'test/:id':'openAlbum',
    },

    album:function(){
        this.albums = new album.albumCollection()
        this.albumsView = new album.albumCollectionView({model:this.albums})
        this.albums.fetch({reset: true})
    },
    openAlbum:function(id){
        this.images = new image.imageCollection()
        this.imagesView = new image.imageCollectionView({model:this.albums})
        this.images.fetch({reset: true})
    }
})

new album.router();
Backbone.history.start();

我可以渲染相册，但是当我尝试打开相册时，你可以看到我需要通过相册的ID来获取图像集，但是imageCollection.url是静态的。

如何在带有骨干和tastypie的相册中获取图像？

Answer 1

在Image tastypie资源的相册字段中设置filtering并更改网址以按相册过滤图片：

openAlbum:function(id){
    this.images = new image.imageCollection()
    this.images.url = this.images.url + "?album=" + id;
    this.imagesView = new image.imageCollectionView({model:this.images})
    this.images.fetch({reset: true})
}

Django tastypie和骨干专辑应用程序？
