rails中把文件上传到文件夹中,一般有图片,rar文件等等,试着找了些rails file upload的plugins (fleximage,attachment_fu,paperclip.....),但是最后发现都不是太好用,最后利用原始ruby api实现了,实现步骤:
rhtml:
<form name="photo" enctype="multipart/form-data" action="/upload/path" method="post">
Photo <input type="file" name="image" id="image" size="30" />
<input type="submit" name="upload" value="Upload" class="button" />
</form>
controller:
path = 'public/data'
File.open(path, "wb") { |f| f.write(params[:image].read) }
that's all,简单吧。。注意在用File类的一些方法时,需要require 'ftools'
