我正在尝试处理上传文件的问题,这些文件不是带有动作文本的图像,并使它们对查看帖子的用户起作用。例如,如果在创建某些内容时上传了PDF,则用户应该能够下载。
现在我的图片上传得很好,显示也很好,但如果我上传了PDF,它会显示回文件名和大小:
Bla.pdf 635 KB。这看起来像是可点击的,也是不可点击的:

下面的html是:

<span class=”attachment__size”>635 KB</span>
</figcaption>
</figure></action-text-attachment>你知道我怎么才能让它可以下载吗?
谢谢

你需要改变
app/views/active_storage/blobs/_blob.html.erb就像这个
<figure class="attachment attachment--<%= blob.representable? ? "preview" : "file" %> attachment--<%= blob.filename.extension %>">
<% if blob.representable? %>
<%= image_tag blob.representation(resize_to_limit: local_assigns[:in_gallery] ? [ 800, 600 ] : [ 1024, 768 ]) %>
<figcaption class="attachment__caption">
<% if caption = blob.try(:caption) %>
<%= caption %>
<% else %>
<span class="attachment__name"><%= blob.filename %></span>
<span class="attachment__size"><%= number_to_human_size blob.byte_size %></span>
<% end %>
</figcaption>
<% else %>
<%= link_to blob.filename, rails_blob_path(blob) %>
<% end %>
