I’m using attachment\_fu for uploading photos. I’d like to set the  
max\_size parameter based on the user’s account level. So I have a field  
in the account\_plans table that stores the max\_size allowed for that  
plan.

This doesn’t work, but it should give an idea of what I’m trying to  
achieve…

has\_attachment :content\_type =\> :image,  
:storage =\> :s3,  
:path\_prefix =\> ‘public/uploaded\_photos’,  
:max\_size =\>  
self.event.account\_plan.max\_filesize.kilobytes,  
:s3\_access =\> :public\_read

What is the correct way for me to do this?

Thx  
Nick
