Spinejs. Has no method 'hasMany'

Question

I have problem with spinejs associations.

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

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

but it writes an error

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

What I am doing wrong? Thanks in advance.

Have you included the relation.js file? Per the 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.
