Spinejs。沒有方法'hasMany'

Question

我有Spinejs關聯的問題。

class Category extends Spine.Model 
    @configure 'Category', 'name', 'id' 
    @extend Spine.Model.Ajax 

    @hasMany 'children_categories', 'Category' 
    @url: Route.categories() 

，但它將錯誤寫入

Uncaught TypeError: Object Category(name, id) has no method 'hasMany'

我做錯了嗎？提前致謝。

您是否包含relation.js文件？根據documentation：

Spine's relationship logic is available in a separate module to the rest of the library, relation.js. You'll need to include that in your application before continuing.
