In model I have something like

has_attached_file :logo, something_here

Code/ Uploading logo is working fine, but I need dimensions before
uploading the logo. So when I am using geometry, error is thrown for

undefined local variable or method 'logo' for #<Class:0xbfabbc0>

Any idea how to solve this? Or is there any other way to get the
dimension before storing the data.
