打印模型在视图中计数(MVC)

Question

我想在我的网站前面放一些统计信息,例如:

# jobs/index.html.haml
.panel
    .panel-heading
        %h4 Statistics
    .panel-body
        .col-md-9.col-xs-9
            %h5.pull-left Users
        .col-md-3.col-xs-3
            %h5.pull-right= @usercount

        .col-md-9.col-xs-9
            %h5.pull-left Companies
        .col-md-3.col-xs-3
            %h5.pull-right= @companycount

        .col-md-9.col-xs-9
            %h5.pull-left Categories
        .col-md-3.col-xs-3
            %h5.pull-right= @categorycount

        .col-md-9.col-xs-9
            %h5.pull-left Total offers gathered
        .col-md-3.col-xs-3
            %h5.pull-right= @jobcount

目前这些变量都在控制器中设置:

# controller: jobs, action: index
@jobcount = Job.count
@usercount = User.count
@categorycount = Category.count
@companycount = Job.distinct.count('company')

但我相信这是在MVC中做到这一点的最糟糕方式.谁能告诉我应该怎么做？

Answer 1

我会选择这种风格： @statistics = { job_count: Job.count, user_count: User.count, category_count: Category.count, company_count: Job.distinct.count('company') }
