Hello friends,  
I have a query like I am using a attchment\_fu to store images.  
But the i don’t want to store to the default path let say :path\_prefix  
=\>  
‘public/uploads’ i want a dyname path for e.g :path\_prefix =\> ‘public/#{  
current\_user.id}’, So just wanted to know how can i say images to the  
dynamic location.

Regards  
Abhishek S.

Have you tried this like

:path\_prefix =\> “public/#{\> current\_user.id}”

```
 Instead of single quotes use double quotes

```

Ok great things are working fine. but again i have a major concern when  
I am  
declaring it like

:path\_prefix =\> “public/user\_#{current\_user.id}”

in background it save the image in the following folder structure

“public/user\_/123/\_image.jpg”

And i am looking something like

“public/user\_123/\_image.jpg”

Actually it’s creating a just “user\_” folder which i don;t want, i want  
to  
have “user\_123”.

Thanks  
Abhis
