Problem with attachment_fu and ImageScience

Hi,

I''m having trouble getting the attachment_fu plugin to generate
thumbnails. I''m using ImageScience and everything worked flawlessly on
my laptop, but on the deployment server no thumbnails are being
generated. Both boxes are Linux. I forced the same Rails version on
both:
RAILS_GEM_VERSION = ''2.0.2'' unless defined? RAILS_GEM_VERSION

Generating the thumbnails simply fails silently, there is no error
message or log entry whatsoever. Generating a thumnail manually on
script/console works, so I guess ImageScience is installed correctly.
To find out more I tried "rake test" in the attachment_fu directory.
There were a lot of errors, most probably because ImaceScience is the
only processor installed, but this one startles me:

13) Error:
test_should_resize_image(ImageScienceTest):
ActiveRecord::SubclassNotFound: The single-table inheritance mechanism
failed to locate the subclass: ''NULL''. This error is raised
because
the column ''type'' is reserved for storing the class in case of
inheritance. Please rename this column if you didn''t intend it to be
used for storing the inheritance class or overwrite
ImageScienceAttachment.inheritance_column to use another column for
that information.

`test_should_resize_image''

I can''t really figure out what this means. After all, attachment_fu
works perfectly on my laptop using the same version of Rails.

Any hints about this...?

Best regards,
Victor

Re: Problem with attachment_fu and ImageScience

Victor,

I have found production/test deployment oddities can be resolved by
switching your local "development" into "production" mode to
force
Rails to behave like it would on your server.

The quickest way to do this is to edit your database.yml and copy your
"development:" block and rename to "production:". Then
change the name
of the original "production:" block to something else like
"production_off:". Restart your local development server but add the
"-
e production" or just "production" argument and you might find
the
same behavior. Now have eliminated your server as the culprit of the
issue. For example, it could be a problem in the way you are using
attachment_fu. Development mode and production mode are not 100%
congruous in my experience.

secondly, make sure you are not using reserved column names in your
tables. This looks suspicious in that regard:

...The single-table inheritance mechanism
failed to locate the subclass: ''NULL''....

A good example is a "type" column. This is reserved for polymorphism
and can introduce some unwanted automagically ActiveRecord behavior.

Re: Problem with attachment_fu and ImageScience

Hank,

thanks a lot for your answer! Actually, I''m still in development mode
on the server - didn''t even dare touching this yet. I''m really
startled by the fact that the test complains about a "test" column.
There is none, I just double-checked the database and the migrations.
There is a "content_type" column because it''s needed by
attachment_fu,
but I suppose this shouldn''t be a problem. After all, I still really
don''t understand why it works on my laptop but not on the server using
exactly the same versions of Rails and attachment_fu.

The error about the "test" column occurs when running "rake
test" in
the attachment_fu directory. Are there any other places that could
have database definition? I noticed that "rake test" doesn''t
print any
errors when run in the attachment_fu directory on my laptop.

Best regards,
Victor

Re: Problem with attachment_fu and ImageScience

Hi everybody,

I got it working by dumping Debian Etch''s packages and installing from
source/gem. Guess Debian messed something up... Or there was a version
incompatibility I didn''t realize. Who know; anyway, my project is back
on it''s rails. ^^

Best regards,
Victor

Re: Problem with attachment_fu and ImageScience

Ahh. rake test.

Well look at all your test fixtures. there is probably a column in one
of those files that does not exist in real life.
