Question

当我尝试渲染列表分页作业时，尽管包含了所有这些项目的数组。发生了什么事？ http://take.ms/9HtCa

jobs_controller.rb

def index
  @joblist = Job.page(params[:page]).per(20) 
   render 'jobs/index'
end

index.html.haml

.row-fluid
  .span8.hidden-desktop
    =render 'job'

  .span4
    .center
      .add-job
        =link_to "добавить вакансию", new_job_path

_job.html.haml

%span
  =@joblist.each do |job|
    %ul
      .job-item
        %span
          .fl-l
            =job.title
          .fl-r
            =succeed ',' do
              =Country.find_by_id(job.country_id).name
            =City.find_by_id(job.city_id).name
          %br
        %span
          .fl-l
            =job.jobtype
        %br

  =paginate @joblist

Answer 1

在=之前移除@joblist.each。它显示由表达式返回的值，每个都返回它迭代的数组。

Answer 2

=应为-

=呈现输出，但-评估ruby表达式。
