and dont forget to add height and width to the attr_accessible list and
fix
this
height = dimensions.height
width = dimensions.width
to
self.height = dimensions.height
self.width = dimensions.width
also you can remove the style from
has_attached_file :photo, :styles => {
:original => [“100%”, :jpg] ,
}
to
has_attached_file :photo
and you have an extra comma that does not goes there
at the end it should look similar to this
has_attached_file :image,
:url => “/system/assets/images/:id/:style/:basename.:extension”,
:path =>
“:rails_root/public/system/assets/images/:id/:style/:basename.:extension”
validates_attachment_presence :image
validates_attachment_size :image, :less_than=> 800.kilobytes
validates_attachment_content_type :image, :content_type =>
%r{image/.*}
the red charactesr means you should but the size you want there, you can
remove
validates_attachment_size :image, :less_than=> 800.kilobytes
if you dont want to set a limit.

my replies have many typos , some time i write ‘user’ instead of
‘used’
and ‘is’ instead of ‘if’
you may want to check that in case something is not clear
sorry im an idiot
def after_save
uploaded_file = photo.queued_for_write[:original]
dimensions = Paperclip::Geometry.from_file(uploaded_file)
height = dimensions.height
width = dimensions.width
end
end
is after save not before, in the before
Paperclip::Geometry.from_file(uploaded_file) does not exist
let me go check that because rigth now im telling you everything from
memory, ill go see the right way to do it and the reply to you

did you created the fields in the database? do that and it should work
Yes, I have created the fields in the database as follows:
rails script generate migration AddWidthToDicom width:integer
And,
rails script generate migration AddHeightToDicom height:integer
But, still the same.
