How to write unit tests with respect to model callbacks?
Hello,
I am exploring the "Testing" part of Rails, but It seems some things
work differently than I thought it would.
Consider the following model:
class Client < ActiveRecord::Base
has_one :project
def after_create
Project.new(:name => self.name, :is_client => true, :client_id
=> self.id).save
end
def after_update

STI, HABTM & counter_cache

tricky form validation
Hi list,
I want to create a form validation in my Marketing Model.
I want to raise an error only if a previous marketing campaign for a
property has not been completed (ie. ended_on IS NULL)
I managed to get this working in the Controller using something this:

consistent segfaults in ROracle with one of the databases
Dear list.
Has anybody had any issues with ROracle, namely consistently leading to
a segmentation fault? One of our oracle databases seems to have certain
issues at the moment (do not know what exactly though) and if that one
is queried ROracle definitely fails with a segmentation fault. Any
ideas? Here is the trace and below is also a type of query that crashes
it:

acts_as_metadata?
I''m running into the need (on at least one project now) to implement
end-user-customizable "metadata" or properties on model objects. The
standard example would be a Person class that had first_name,
last_name, etc. but would need to be extended real-time (through the
web admin interface) with properties such as phone_number : varchar
(30). I''ve done some basic

a new directory service
Hello. About your idea, I think that it is important for a radio
to "check" multiple styles.
I'm planning to cast a couple or 3 of stations that are _not_
monographic and will be "sports" from x to y hours, "pop" from
y to z hours, "talk" from z to p hours and so on.
That is because people that are listening the same genre for
hours want to change. Why

class Person < ActiveRecord::Base
has_many :workers

SOAP + HTTP authentication
Hey,
Just had a question. Been pulling out my hair all weekend trying to get SOAP
to work properly in Rails and even straight on Ruby. I started with Rails''
AWS and moved to Ruby''s internal libraries, after which I tried out SOAP4R.
Now, my question is, does Rails or even Ruby itself support SOAP client
calls through basic HTTP Authentication? From the research I''ve

can't get write_sectors to work...
Hi,
Hopefully you someone can tell me what I'm doing wrong. First, the code. I
placed this at the bottom of the main loop in com32/modules/disk.c as a
simple test of writing to the disk:
printf(" Host bus: %s, Interface type: %s\n\n",
d->edd_params.host_bus_type, d->edd_params.interface_type);

counter_cache is not looking for children_count with acts_as_tree
Hi there, the acts_as_tree API says that I can set a counter cache and
that it will automatically increment the "children_count" column. I
did that but when I create a new page it asks for a "pages_count"
column instead.
Here is the relevant part of page.rb model:
class Page < ActiveRecord::Base

Strange behavior of Source.column_names
I have a class named Source and a controller named SourceController
etc.
When I use Source.column_names in the view all names except names
ending in _id is listed, although according to the documentation all
names should be listed
When I use Source.column_names in the source controller it lists
correctly all names also the ones ending in id.

bitstream changes
ok now I see why we need another packet in the header. The first one is basically for ID purposes (theora_decode_header()). I've jammed my huffman trees in there but it sucks because I need them later on when I actually build the huffman tree structs (theora_decode_init, calls InitHuffmanSet()). At that point the original header packet is gone so I've been keeping it around in a buffer.

ActiveRecord and refreshing column info
Let''s say I want to find out what column names exist in two tables,
table_a and table_b.
One way I''ve been doing this is using ActiveRecord and the column info
it returns. After establishing a connection for ActiveRecord, I do the
following:
ActiveRecord::Base.set_table_name("table_a")
column_names_a = ActiveRecord::Base.column_names

Connection problem with a generic-runtime-built ActiveRecord::Base
Hi,
I''m trying to create a "runtime-generic" ActiveRecord
class, It means I don''t need to know the table or
database, before I create my program ruby-rails. So I
don''t need to predefine my database in environment.yml
file and pre-build classes inherited from
ActiveRecord::Base.
I write some code, it seems to work. However, I can''t
