Carrierwave是一个处理文件上传的好工具， https://github.com/jnicklas/carrierwave#making-uploads-work-across-表单重新显示

I have form with multiple file uploads, The issue is when i am submitting the form and an validation error occurs, the file input field gets reset.

I basically wanted to persist those files inside the file input field for the complete process.

I have also gone through few links

How can I "keep" the uploaded image on a form validation error?

Please let me know what are the various options in such cases that one can follow.

Carrierwave is a great tool for handling file uploads and can handle this for you
