Approaches to adding attachments in rails3?

I'm wondering what are some good solutions to adding attachments/files to records in rails3?

I'm talking about any kind of file, with user set upload limits.. Is this something paperclip can handle? If not are there any other/better/different solutions out there that people recommend I look into?

Or does anyone have any 开发者_开发问答pointers for how I might go about this from scratch?

Thanks!

You can use or paperclip or CarrierWave gems:

• https://github.com/thoughtbot/paperclip
• https://github.com/jnicklas/carrierwave

Usefull Ryan's screencasts:

• http://railscasts.com/episodes/253-carrierwave-file-uploads
• http://railscasts.com/episodes/134-paperclip

Both of them can handle a number of useful validations
