ruby​​ on rails中activemodel序列化程序的可選屬性

Question

我有以下兩個Serializer類。在索引控制器中，我想跳過加載project_products，只顯示/編輯我想要獲取project_product的詳細信息的方法。

class ProjectSerializer < ActiveModel::Serializer 
     attributes :id, :name, :category, :project_category_id, :status, :description 
     has_many :project_products 
    end 

class ProjectProductSerializer < ActiveModel::Serializer 
    attributes :id, :name, :quantity 
end 

控制器：

def index 
    respond_with @projects 
    end 

def load_projects 
    @projects = current_organization.projects.includes(:project_category) 
    end 

Answer 1

嘗試重寫關聯方法

class ProjectSerializer < ActiveModel::Serializer 
     attributes :id, :name, :category, :project_category_id, :status, :description 
     has_many :project_products 

    def project_products 
     if current_page?(edit_path_url) 
      object.comments 
     else 
      object.comments = nil 
    end 

end 

Answer 2

創建串行實例時，您可以使用 「除」 參數：

respond_with @projects, except: project_products 

（當索引控制器動作時）
