我正在尝试使用AdminSerializer
将@admins转换为JSON#app/serializers/admin_serializer.rb
class AdminSerializer < ActiveModel::Serializer
attributes :id, :email, :access_locked?
end
其中管理员是&gt;&gt; @admins = @search.result(:distinct => true).page(params[:page][:number]).per(10)
和@search = Admin.search(params[:q])
执行此命令时&gt;&gt; ActiveModel::SerializableResource.new(@admins.to_a).as_json
我确实获得了所需的JSON,但收到的JSON中缺少分页链接,因为在使用@admins
将to_a
转换为数组时丢失了这些链接。
但是,当我执行render :json => @admins
时,我会获得带有分页链接的完整JSON,如下面的屏幕截图所示:

在可用的latest commit中,您需要使用:
resource = ActiveModel::SerializableResource.new(@admins)
resource.to_json(serialization_context: ActiveModelSerializers::SerializationContext.new(request))

我用kaminari这是很棒的分页宝石 我无法在json响应中添加paginataion 但是我找到了自定义代码。
#your controller#index
require 'pagination'
...your code
render json: Pagination.build_json(@posts, @comment_page, @comment_per)
# /lib/pagination.rb
class Pagination
def self.build_json object, nested_page = 1, nested_per = 10
ob_name = object.name.downcase.pluralize
json = Hash.new
json[ob_name] = ActiveModelSerializers::SerializableResource.new(object.to_a, nested_page: nested_page, nested_per: nested_per)
json[:pagination] = {
current_page: object.current_page,
next_page: object.next_page,
prev_page: object.prev_page,
total_pages: object.total_pages,
total_count: object.total_count
}
return json
end
end
