如何讓redmine中問題或論壇中圖片附件自動預覽

最近公司在推行redmine用做專案管理的工具來使用，但是在新增加任務或者論壇訊息時候有個問題，新增加圖片的話，在查看問題或訊息的時候，無法預覽，必須點擊一次，在新視窗開啟，非常費事，所以考慮是不是有什麼方法可以解決這個問題，於是就看到了“redmine_lightbox”有相關的代碼，於是將之複製到redmine裡面，一實驗，果然可以，貢獻：

修改 app\views\attachments\_links.rhtml這個檔案，如果顯示全圖的話，增加以下代碼即可：

 

<SPAN style="FONT-SIZE: medium"><% images = attachments.select { |a| a.image? } %><% unless images.empty? %><div class='images'><% images.each do |attachment| %><%= link_to image_tag(url_for({:controller => 'attachments', :action => 'show', :id => attachment, :filename => attachment.filename })),{:controller => 'attachments', :action => 'show', :id => attachment, :filename => attachment.filename }, :class => 'lightbox', :rel => 'attachments', :title => "#{attachment.filename}#{ ('-' + attachment.description) unless attachment.description.blank? }" %><% end -%></div><% end -%></SPAN>

如果希望先顯示的 預覽圖片，則需要增加：多了一個參數“width => '180'”180就是你設定的寬度

 

<SPAN style="FONT-SIZE: medium"><% images = attachments.select { |a| a.image? } %><% unless images.empty? %><div class='images'><% images.each do |attachment| %><%= link_to image_tag(url_for({:controller => 'attachments', :action => 'show', :id => attachment, :filename => attachment.filename }), :width => '180'),{:controller => 'attachments', :action => 'show', :id => attachment, :filename => attachment.filename }, :class => 'lightbox', :rel => 'attachments', :title => "#{attachment.filename}#{ ('-' + attachment.description) unless attachment.description.blank? }" %><% end -%></div><% end -%></SPAN>
