我正在尝试添加分页器和搜索。直到我添加pg_search,它都可以正常工作。 pg_search转到正确的URL,但不过滤搜索结果。例如,如果我输入Vere Lee-http://localhost:3000/admin/dashboard?utf8=%E2%9C%93&search=Vera+Lee&commit=,它将粘贴到同一页面而不进行过滤。如果我没有使用分页器,pg_search似乎可以正常工作。
有没有办法将两者结合起来?
控制器
class AdminController < ApplicationController
before_action :require_login
def dashboard
@users = User.joins(:filled_documents).group("users.id").having("count(filled_documents.id) > ?",0).order("created_at ASC").paginate(page: params[:page], per_page: 5).perform_search(params[:search])
end

要解决加入和分组的问题,您可以使用belongs_to :user, counter_cache:true
(还需要进行迁移以将filled_documents_count
整数字段添加到用户表并填充初始值)
分页器通常也是链中的最后一个作用域:
@users = User.where("filled_documents_count>?", 0)
@users = @users.perform_search(params[:search]) if params[:search].present?
@users = @users.order("created_at ASC").paginate(page: params[:page], per_page: 5)
但是请注意,counter_cache
在对同一用户的文档可以有多个并发写入时效果不佳。
