I have installed the file\_column plugin:  
in my model i have this code:

validates\_file\_format\_of :image, :in =\> [“gif”, “png”, “jpg”], :message  
=\> ‘must be an image file’  
validates\_filesize\_of :image, :in =\> 0…800.kilobytes,  
:too\_large\_message =\> ‘mettine una + piccola’

file\_column :image,:magick=\>{  
:geometry=\>‘600x600\>’,:attributes =\> { :quality =\> 60 },  
:versions =\> {  
:thumb =\> {:crop =\> “1:1”, :geometry =\>“30x30”,:attributes =\> {  
:quality =\> 50 } },  
:thumb\_big=\>{:crop =\> “1:1”, :geometry =\>“62x62”,:attributes =\>  
{ :quality =\> 50 } }  
}  
}

validates\_filesize\_of not works.

Why?  
How i can do?  
Thanks
