In our latest application we need to process some uploads, I’ve worked with paperclip before and everything just works! but we’re giving carrierwave a try, it looks promising but, I can’t find how to validate the size of an attachment, it seems like the documentation doesn’t have any information about it, should we add it manually to the model via a custom validator?

Thanks in advance!

    There is a Wiki entry on github: https://github.com/jnicklas/carrierwave/wiki/How-to%3A-Validate-attachment-file-size
