Rails-Project.where（created_at：（Time.now-24.hours）.. Time.now）返回<Project::ActiveRecord_Relation:0x007f5470c7a378>

Question

我想做的是統計過去24小時內發布的所有項目。

class ApplicationController < ActionController::Base

  before_action :projects_today

  def projects_today
    @projects_today = Project.where(created_at: (Time.now - 24.hours)..Time.now)
  end

end

視圖

<h1><%= @projects_today %></h1>

但是，視圖中顯示的是“ Project :: ActiveRecord_Relation：0x007f5470c7a378”，而不是所需的答案62。

Answer 1

您忘記添加count ：

@projects_today = Project.where(created_at: (Time.now - 24.hours)..Time.now).count
