如何让redmine中问题或论坛中图片附件自动预览

Posted 2022-12-14 ycyk_168

最近公司在推行redmine用做项目管理的工具来使用，但是在新增加任务或者论坛消息时候有个问题，新增加图片的话，在查看问题或消息的时候，无法预览，必须点击一次，在新窗口打开，非常费事，所以考虑是不是有什么方法可以解决这个问题，于是就看到了“redmine_lightbox”有相关的代码，于是将之复制到redmine里面，一实验，果然可以，贡献：

修改 app\\views\\attachments\\_links.rhtml这个文件，如果显示全图的话，增加以下代码即可：

 

<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>

如果希望先显示的 预览图片，则需要增加：多了一个参数“width => '180'”180就是你设置的宽度

 

<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>
