Hi,
Firstly, thanks to Sebastian Kanthak for an excellent plugin! It works
marvellously for uploading and resizing images, but I''m getting the
dreaded
url_for_file_column returns nil error.
Using:
file_column 0.3.1
Rails 0.14.3
Ruby 1.8.2-1
Debian Sarge
I am using an instance variable as required in my view. image_relative_path
also returns nil. Any pointers?
new.rhtml:
<%= file_column_field "recipe", "image" %>
show.rhtml:
<%= image_tag url_for_file_column("recipe", "image")
%>
controller:
@recipe = Recipe.find(params[:id])
(and is confirmed not to be nil)
NoMethodError:
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.first
thanks

If that's the case, then that is your problem. You have to code around it: <% if @recipe.image.nil? then -%> <em>No image</em> <% else -%> <%= image_tag url_for_file_column ... %> <% end -%> -- François Beausoleil http://blog.teksol.info/ _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails

You have to code around it:Yes, it is nil, which is exactly the problem - this is for a @recipe for which an image has been uploaded, resized, and saved by file_column. I had exactly that same code in place which resulted in no images being displayed at all. Any ideas about where I should be looking for clues? thanks -- Mark Beattie Easy Schedule Management http://easy-online-schedule.com

Try to open the Rails console and check the recipe manually: ruby script/console r = Recipe.find(ID) r.image r.image should return the path to the image. If that comes back as nil, then your image was never put in the DB in the first place. Check the place where you upload and add debugging information there. You might also want to add an after_save callback to print the path to the image, at least temporarily. Additionaly, unit testing Recipe image uploading might be a good idea. Hope that helps ! -- François Beausoleil http://blog.teksol.info/ _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails

Could I just as easily have two files associated with an object, such as an image and an attachment of unknown type using 2 file_column declarations in the model assuming it''s table has a field to store the filename of each? class Foo < ActiveRecord::Base file_column :image, :magick => { :geometry => "640x480>" } file_column :attachment end Sorry to have bothered you, and thanks again. -- Mark Beattie Easy Schedule Management http://easy-online-schedule.com
Hi Mark, I''m glad you like the plugin...

You''ll need two different columns in your database and two different file upload fields, though. Sebastian
