Htmlpdfに直リンクする(ダウンロードしない)方法
Add to app/models/attachment.rb, somewhere next to def thumbnailable:
def pdf?
!!(self.filename =~ /.(pdf)$/i)
end
Then modify app/controllers/attachments_controller.rb:
Change the line:
:disposition => (@attachment.image? ? 'inline' : 'attachment')
to
:disposition => (@attachment.image? || @attachment.pdf? ? 'inline' : 'attachment')
