I followed the instructions on Mike Clark''s weblog and everything
works perfectly except the thumbnail column in my DB is alwas NULL.
I''m using S3 as my storage system. Anyone else having this issue with
thumbnails?
has_attachment :content_type => :image,
:storage => :s3,
:max_size => 500.kilobytes,
:resize_to => ''150x150>'',
:thumbnails => { :thumb => ''40x40>''
},
:processor => ''Rmagick''
validates_as_attachment

I first started out with trying to use ImageScience. I followed the
directions correctly on their website and within my app when I try to
upload an image it shuts down mongrel/server with this error:
/Users/Bob/work/app/trunk/vendor/plugins/attachment_fu/lib/
technoweenie/attachment_fu/processors/image_science_processor.rb:14:
[BUG] Bus Error
ruby 1.8.4 (2005-12-24) [i686-darwin8.8.1]
Abort trap
Fair enough, I''ll just try minimagick and see if that works. When I
run: gem install mini_magick I get this error:
ERROR: While executing gem ... (Errno::EACCES)
Permission denied - /usr/local/lib/ruby/gems/1.8/cache/
mini_magick-1.2.0.gem
So it looks like Rmagick is the only one that is working but
attachment_fu is not saving thumbnails. Ideally I would like to use
ImageScience but I cannot spend all day working on this image upload
problem. Anyone know what I''m doing wrong?

try installing mini_magick again but put a sudo in front: sudo gem install mini_magick are you on a mac ? I assume you are trying to install it locally and that you have the appropriate permissions.

jko170 wrote:> Anyone know why the thumbnails are not being created while everything > else is working fine?I ran into this a few weeks ago using a Flash upload widget, and it turned out that the uploader wasn''t sending the proper MIME type -- everything was application/octet-stream, so attachment_fu wasn''t recognizing the file as an image. I just rewrote the uploaded_data method of attachment_fu to check against a table mapping file extensions to MIME types when it found a file type of application/octet-stream. The hack seems to work for my purposes. --Al Evans -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for the replies. I installed mini magick correctly and thumbnails are still not generated. I doesn''t matter what image processor I use so I''m assuming that''s not the problem. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Here is all my code incase someone can spot something:
create_table "photos" do |t|
t.column :user_id, :integer, :null => false
t.column :content_type, :string
t.column :filename, :string
t.column :thumbnail, :string
t.column :size, :integer
t.column :width, :integer
t.column :height, :integer
end
class Photo < ActiveRecord::Base
belongs_to :user
has_attachment :content_type => :image,
:storage => :s3,
:max_size => 500.kilobytes,
:resize_to => ''150x150>'',
:thumbnails => { :thumb => [50, 50], :geometry =>
''x50'' },
:processor => ''MiniMagick''
validates_as_attachment
end
def create
@user = User.new(params[:user])
@photo = Photo.new(params[:photo])
@user.photo = @photo
if @user.save && @photo.save
flash[:notice] = ''User was successfully created.''
redirect_to user_url(@user)
else
render :action => "new"
end
end

Hi, You need to have a ''parent_id'' column in your photos table. This one had me scratching my head for a few hours too until I stumbled across this requirement of the plugin. See the tutorial: http://clarkware.com/cgi/blosxom/2007/02/24 He doesn''t mention that parent_id is required however.

That fixed it. Thanks Guy! One more quick question: Do you know how to make the thumbnail and images resize to an exact size? I guess that would require cropping? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

this is a great thread and helped me get my hands around debugging this thing. some more tips -- 1 here''s another thing to look for with respect to parent_id: if you''re using uuid (string) instead of id (integer) make sure your parent_id is also a string and not an integer, otherwise you won''t get thumbnails 2 if you''re a windows user, ruby is faster than windows so for your create and update actions (assuming REST) make sure you stick in a sleep(2) to allow windows to catch up to your rails app when you post: def create sleep(2) .. def update sleep(2) .. -- Posted via http://www.ruby-forum.com/.
