Call AR belongs_to association accessor ID method on object assignment
Hi,
Haven''t been able to find this raised before but I''m sure it must have
been. When assigning an object to a belongs_to association I would
like it to call the *association*_id= method instead of directly
updating the attributes array. This is because I want to modify the
behaviour when assigning a particular object without writing separate
methods for whether it''s

Setting DEFAULT_FIELD_OPTIONS in Rails 2.3
Hi,
I''m having some trouble overriding/defining the default_field_options
constant without raising a warning. I''ve tried adding the code to do
it in an initializer but that produces a warning (because the constant
is already frozen), after some googling I found a recommendation to
put it in the environment.rb file but that then that throws

MiniMagick, and processing thumbnails...
I have a requirement that can''t be that outrageous....
I want to be able to upload an image, and have multiple thumbnails be
created for each. Then, I want to post process each image (the main
image plus the thumbnails) to add borders. The trick is that the
borders need to be different for each image. I thought I could use
the after_resize handler, but when I try to add a border to

Rails 4.0 Example app
Hi All,
I have 30 years as a self employed software engineer and have been
experimenting with rails for several years but !!
I would have made considerably more progress and been able to give back to
the community if only there was a demo application that was released with
each new rails release.
I am sure that it would take no more than 15 minutes of someone within the
core team to produce

Re: Stubbing out ThinkingSphinx for Rspec
Thanks Wolas!
Sorry if this seems like a newbie question, what am I supposed replace
the stubbed_method_name with?
Also, I came across the only thread on the Interwebs which seems to
cover this topic - it''s over a year old, but I think they have a

Desktop Choice Centos 4/Centos 5 or Fedora 9
I have a choice of CentOS 4/5 and Fedora 9 on a laptop.
I have not use CentOS 5 on a desktop but have used
CentOS 4 and Fedora 9. I found the Fedora Gnome not
as appealing as the CentOS 4 clearlooks. Any opinions
from someone who has used CentOS 4/5 and Fedora?
I'm not a KDE fan so KDE users need not reply.

acts_as_ferret with conditions
Hello guys,
Having a slight problem with acts_as_ferret, specifically using a
condition. I have the following code
@results = SupplierProduct.find_by_contents(params
[:search], :conditions => [''area_id = ?'', @area])
and it seems the condition isn''t being applied. Does anyone have any
pointers?
