rails_admin & carrierwave

Hi to all.... Please help me =(
I use rails_admin and I need to upload files with the help of it.
I found carrierwave for it and installed it with the help of
https://gist.github.com/884835. But It doesn't work =( when i login in
rails_admit? i see default text field instead field for choose a file,
but this text field without CSS styles of rails_admin. I think, that my
views, which i created for carrierwave, are not render in my app. Why???
((((( help please.
