Image dimensions

[greg]

I'm trying to store image dimensions with the following...and while
I'm not getting errors, the dimensions aren't being stored.

What should I be putting in my controller to make sure the dimensions
are stored? Or how would be best to get if img is actually showing
any dimensions? I don't see them passing in the terminal. Thank you!

class ImageUploader < CarrierWave::Uploader::Base
include CarrierWave::RMagick
# ...
process :store_geometry
def store_geometry
if @file
img = ::Magick::Image::read(@file.file).first
if @post
@post.width = img.columns
@post.height = img.rows
end
end
end
# ...
end

The uploader belongs to a post? Then you should do model.width, etc.

Post is the name of my model. I've tried leaving as just model or
using Post, but no data is being passed through.

Is there anything I should be putting into my controller?

process :store_geometry
def store_geometry
if @file
img = ::Magick::Image::read(@file.file).first

if model
model.width = img.columns
model.height = img.rows
end
end
end

This is what I'm seeing passed in parameters...no height or width
seeming to go through...
