我正在使用will_paginate
和api-pagination
来为我的数据分页,并且使用active_model_serializers
来进行JSON序列化。 我想将资源的全部条目发送到我使用AngularJS的客户端。Rails 5 - 如何使用will_paginate和活动模型序列化程序获取总条目
控制器代码
def index
comp_id = params[:company_id]
cat_id = params[:category_id]
if comp_id
if comp_id && cat_id
product = Product.where(:company_id => comp_id, :category_id => cat_id)
else
product = Product.where(:company_id => comp_id)
end
paginate json: product,meta: pagination_dict(product), status: 200
else
render json: { errors: "Company ID is NULL" }, status: 422
end
end
串行
class ProductSerializer < ActiveModel::Serializer
attributes :id, :name, :mrp, :sp, :cp, :stocks, :isPublished
has_one :category
end
我怎么能包括我的回应的TOTAL_COUNT?
更新
我尝试添加下面的方法在我的基本控制器按this文档,但是我得到未定义的方法错误定义的所有方法。
class ApplicationController < ActionController::Base
include Authenticable
include Rails::Pagination
rescue_from ActiveRecord::RecordNotFound, :with => :render_404
protect_from_forgery with: :null_session
def render_404
render json: { errors: 'The requested resource cannot be found' }, status: 404
end
def pagination_dict(collection)
{
#current_page: collection.current_page,
#next_page: collection.next_page,
#prev_page: collection.prev_page, # use collection.previous_page when using will_paginate
total_pages: collection.total_pages,
total_count: collection.total_count
}
end
end
