我正在使用will_paginate
和api-pagination
來爲我的數據分頁,並且使用active_model_serializers
來進行JSON序列化。 我想將資源的全部條目發送到我使用AngularJS的客戶端。Rails 5 - 如何使用will_paginate和活動模型序列化程序獲取總條目
控制器代碼
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
我怎麼能包括我的迴應的TOTAL_COUNT?
更新
我嘗試添加下面的方法在我的基本控制器按this文檔,但是我得到未定義的方法錯誤定義的所有方法。
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
