file_column error --

well ive been trying to get either this plugin or acts_as_attachment to work with my application, and neither have had any success. im going back to looking for help with file_column, ive tried acts_as_attachment all weekend, but im not getting any meaningful errors to help fix it, and my application wont even start. file_column is also giving me problems, but at the same time, I can at least access my application and use it properly, the only time I have a problem with file_column is when it needs to do anything with RMagick it seems. I can upload an image fine simply by declaring file_column :filename in my model, but when I goto add something like :geometry => it errors out with an ugly ImageMagick error thing.

This is the code in my model:

file_column :filename, :magick => { :geometry => "640x480>" }

This is the error im getting below.

NameError in Admin/biographiesController#update uninitialized constant ImageMagickError

This error occured while loading the following files:    magick/image_magick_error.rb

PLEASE ask for more logs and try to be specific what I should be looking for so I know what to include, im still new to this all, so im not always 100% what I need to be doing all of the time..

The form is multipart, the fields are all working properly, but as soon as I try to add the geometry / magick I get the error above.

I have successfully installed ImageMagick, and rmagick. I did the convert logo.miff / imdisplay logo.miff thing and it worked properly, I also did the examples in the rmagick gem folder, and those also worked properly. I just used the basic install of ImageMagick, and told it to update the executable search paths.. but if I need to manually set any paths then I havent done that at all, so let me know about that as well.

sorry about the huge message.. but im running out of options here and I have no idea what on earth is causing it.. espically since everyone else seems to get these working without any problems..

Thanks!!!!!!

try :size => “640x480>”

instead of :geometry => “640x480>”

do you have the RMagick gem installed???

do a ‘gem list’ from the console to check

hey, I tried replace :geometry with :size and I still get the same error.

when I do gem list, I get the rmagick displayed, and as far as I can tell it is working properly based on trying the provided examples.

gem list

rmagick <1.13.0>

     RMagick is an interface between Ruby and... etc

Im sure it will be easier to simply write my own script, I only need it to resize gallery photos once they are uploaded, a few lines of code can accomplish that im sure, would be nice to have this plugin work though.. :frowning:

if ya wanna write your own

just ‘borrow’ the stuff from file column to help you get started

def resize_image(img, img_options, dest_path) begin if img_options[:crop] dx, dy = img_options[:crop].split(‘:’).map { |x| x.to_f } w, h = (img.rows * dx / dy), (img.columns * dy / dx) img = img.crop(::Magick::CenterGravity, [img.columns, w].min, [img.rows, h].min) end

    if img_options[:size]

      img = img.change_geometry(img_options[:size]) do |c, r, i|
        i.resize(c, r)
      end
    end
  ensure
    img.write dest_path
    File.chmod options[:permissions], dest_path

  end
end
