Url Helpers in ActiveModelSerializer 0.10.0?

问题

I know this version is still not officially released but I was checking out rc3 today and I noticed that I can no longer use Rails url helpers inside my serializers. In version 0.8.x, I could do the following:

class BrandSerializer < BaseSerializer
  attributes :id, :name, :slug, :state
  attributes :_links

  def _links
    {
      self: api_v1_company_brand_path(object.company_id, object.id),
      company: api_v1_company_path(object.company_id),
      products: api_v1_company_brand_products_path(object.company_id, object.id)
    }
  end

end

But this is a no go in the new version. What's the best way of resolving this so that I can keep my links in my serializer?

Edit: For now I'm doing the following but would love to hear if there's a more idiomatic way.

class BaseSerializer < ActiveModel::Serializer
  include Rails.application.routes.url_helpers

回答1:

If you add this to your ApplicationController or even probably to the controller generating the response:

serialization_scope :view_context

You can then use the view_context in the serialiser to access the URL helpers (or any view methods really).

Example: view_context.api_v1_company_brand_path(object.company_id, object.id)

I thought this was probably cleaner than including all those URL helpers etc... into the serialiser class.

including the library which had been excluded (as you had done) would most definitely be the shortest route (outside of revising the gem itself, in terms of idiomacy)
