Question

我写了一个插件来抓取最新的问题并在主页上显示它们。所有这些似乎都运行良好，但它只在我第一次重新启动服务器运行它时起作用 - 之后它会缓存＆＃39;从那时起的问题，没有新的问题得到解决。

我已经阅读过一些关于它的内容，似乎我应该编写一个补丁来解决在我的插件中添加额外功能的问题。真的吗？如果是，我应该在after_save行动中添加什么？对于LatestPostsSetup模型也是如此 - 如果我更改了应该显示的最大计数和侧面的值，主页在我重新启动服务器之前不会反映它。

很抱歉，如果这个问题看起来相当微不足道，那我就是ruby的新手。请在下面找到视图帮助代码：

module LatestPosts
    class ViewHookListener < Redmine::Hook::ViewListener

        require  'plugins/latest_posts/app/models/latest_posts_setup.rb'
        setup = LatestPostsSetup.find_by_id(1)

        if setup == nil
          count = LatestPostsSetup::DEFAULT_COUNT
          side  = LatestPostsSetup::DEFAULT_SIDE
        else
          count = setup.max_count
          side  = setup.side
        end

        issues  = Issue.find(:all, :limit => count, :order => "created_on DESC")

        if side == 'left'
           render_side = :view_welcome_index_left
        else
           render_side = :view_welcome_index_right
        end
        render_on render_side, :locals => {:issues => issues}, :partial => "latest_issues/issues"
    end end

我现在已经更改了视图助手以动态呈现html，并且我不必重新启动apache以显示新问题，我不明白为什么这会影响使用一个HTML模板？请找到以下代码：

# lib/latest_posts_hook_listener.rb
module LatestPosts
    class ViewHookListener < Redmine::Hook::ViewListener

        def view_welcome_index_left(context={})
            setup = load_setup()
            if setup[:side] == "left"
                load_issues(setup[:count])
            end
        end

        def view_welcome_index_right(context={})
            setup = load_setup()
            if setup[:side] == "right"
                load_issues(setup[:count])
            end
        end

        def load_setup()
            require  'plugins/latest_posts/app/models/latest_posts_setup.rb'
            setup = LatestPostsSetup.find_by_id(1)

            if setup == nil
                count = LatestPostsSetup::DEFAULT_COUNT
                side  = LatestPostsSetup::DEFAULT_SIDE
            else
                count = setup.max_count
                side  = setup.side
            end

            {:count => count, :side => side}
        end

        def load_issues(count)
            html = '<div class="box" id="statuses">'
            html += '<h3 class="icon22 icon22-users">Latest Issues</h3><ul>'
            issues  = Issue.find(:all, :limit => count, :order => "created_on DESC")
            issues.each do |issue|
                html += <<EOHTML
                  <li>
                      #{link_to h(truncate(issue.subject, :length => 60)), :controller => 'issues', :action => 'show', :id => issue } (#{ format_date(issue.created_on) })
                   </li>
EOHTML
            end
            html += '</ul></div>'
            return html
        end
    end
end

问题发生变化时，Redmine插件视图挂钩刷新
