使用 JasonApi 资源删除链接 Gem

Question

我有一个简单的模型类:

class Country < ApplicationRecord
  has_many :country_categories
  has_many :categories, through: :country_categories
end

class CountryCategory < ApplicationRecord
  belongs_to :country
  belongs_to :category
end

class Category < ApplicationRecord
  has_many :country_categories
  has_many :countries, through: :country_categories
end

和资源：

class CountryResource < JSONAPI::Resource
  has_many :country_categories
 end

当我向 /countries/1?include=country_categories.category 发出 GET 请求时，响应总是会带来很多链接。例如

            "related": "http://api.localhost.local:3000/api/v1/categories/3/subcategories"
          }
        }
      }
    }
  ]
}

所有这些 links 都不会被使用。有什么办法可以删除它们吗？谢谢:)

到目前为止我找到的解决方案是猴子修补资源序列化程序（尽管这个解决方案远非完美）。

module JSONAPI
  class ResourceSerializer

    def link_object_to_many(source, relationship, include_linkage)
  include_linkage = include_linkage | relationship.always_include_linkage_data
      link_object_hash = {}
      link_object_hash[:links] = {} if relationship.always_include_linkage_data
      link_object_hash[:links][:self] = self_link(source, relationship) if relationship.always_include_linkage_data
      link_object_hash[:links][:related] = related_link(source, relationship) if relationship.always_include_linkage_data
      link_object_hash[:data] = to_many_linkage(source, relationship) if include_linkage
      link_object_hash
    end

    def link_object_to_one(source, relationship, include_linkage)
      include_linkage = include_linkage | @always_include_to_one_linkage_data | relationship.always_include_linkage_data
      link_object_hash = {}
      link_object_hash[:links] = {} if relationship.always_include_linkage_data
      link_object_hash[:links][:self] = self_link(source, relationship) if relationship.always_include_linkage_data
      link_object_hash[:links][:related] = related_link(source, relationship) if relationship.always_include_linkage_data
      link_object_hash[:data] = to_one_linkage(source, relationship) if include_linkage
      link_object_hash
    end
  end
end
