Attachment_fu ImageScience FreeImage thumbnail quality
I''ve tried migrating acts_as_attachment to attachment_fu (just to see
if I could replace RMagick with ImageScience+FreeImage), but the
quality of the thumbnails is just horrendous, blurred beyond
recognition (downscaling a 1280x1024 to a few considerably smaller
thumbnails).
Changing attachment_fu to use RMagick again and the thumbnails were
crispy sharp again.

RMagick=bad, ???=good
I know that Zed has made mention of the fact that using RMagick with
mongrel and rails is a bad thing. I''m currently using FlexImage (which
in turn uses RMagick) on my application and really haven''t had too
many problems. We get a restart for memory usage every 8-10 hours on
one mongrel of twelve running, but I''m not sure if that''s an RMagick
issue. Either way,

rails db indexing and through association
Hello,
Say, I have a pictures table, and there are many objects which can have
pictures, so I define a picturable type. Now, to make the query for pictures
more efficient I should index the picture table using both picturable_type and
picturable_id.
Is this the correct approach to indexing the table, or can things be done
better? I want the database retrieval operation to be extremely fast (I

AJAX form inside table - error
Hello,
I need to put an AJAX, form such that it is inside a table, and spans across
few rows.
But, what I am noticing is that, while submitting the form, the data in the
fields is not submitted.
If I move the form outside the table or inside a cell, things work OK, but not
when the form is inside the table and spans few rows. This problem is only
with AJAX forms, regular forms work perfect. I

rails migrations - enhanced usage
Hello,
When I am writing rails migrations, quite often I make mistake in them which
causes the migration tasks to stop halfway with error.
This causes lots of problem, because it results in half of the things in
migrations changed and other half not. Also, as the schema number is changed,
so things cannot be rolled back.
Is there any way to make the entire migration action atomic, i.e.,
