用于PDF和图像的Rails回形针？

Question

I wanted to make user able to upload either PDF or image . I know only for handling image is there anyway to handle both image and pdf?

I can do up to here

Inside Post Model:

  has_attached_file :image
  validates_attachment_content_type :image, :content_type => {:content_type => %w(image/jpeg image/jpg image/png application/pdf application/msword application/vnd.openxmlformats-officedocument.wordprocessingml.document)}

In console:

bin/rails g paperclip post attachment

If it is image then i can do this in view

=image_tag post.image.url(:medium)  
# It is haml syntax

But how do i display download link if it is pdf or let say word file?

Answer 1

Use :original instead of :medium if it's not an image. You probably need to overwrite the detected MIME type for newer word formats since they are detected as zip files.
