set_default_values rocket science - continuing after_initialize/after_find misfeature
Just starting a new thread so that it''s easy to follow.
I just submitted a patch at trac to add a new class method called
"set_default_values" ( not a great name I think ), which lets you do
all kinds of crazy stuff with setting default values.
This ticket is at http://dev.rubyonrails.org/ticket/9093 and example

test/mocks/ in rails directory structure
Anyone ever uses test/mocks/development && test/mocks/test directories ?
If someone does, test/mocks/development doesn''t really seem like a
nice place for putting development environment mocked classes. May be
mocks/ should be moved to RAILS_ROOT ? Or may be it should be removed.
Views ?

counter cache
Hi,
I have two models, employees and departments, and i am using
counter_cache to count the number of employees in a department.
This works great, but employees can change their departments, and the
counter cache does not get updated to reflect this.
Is their a built in way to do this, or do i have to implement my own
before_save hook
thanks

Utility that checks outdated patches
I just noticed I frequently encounter patches that need to be updated
because of applied changes. Maybe this can be automated? Not
automating the "updating of the patch" part, but the part where a
comment is posted to the ticket so the submitter is informed.

no route found to match "/rails/info/properties" with {:method=>:get}
After a new install (Ruby, Rails en Gem) on a newly installed OS. I''m
getting a ''no route found to match'' error. I Googled a bit, and saw
that more people had this problem with older rails versions. I''m on
Ruby 1.8.6, Rails 1.2.3 and Gem is 0.9.4, on a Mac running OS 10.4.9.
Any suggestion is welcome.

How to fake composite primary keys?
I know ActiveRecord doesn''t support composite primary keys, but I need to use
one, and I need it ASAP. I don''t need any composite foreign keys, luckily;
what I have is a table that stores old versions of rows in another table, so
the composite key is an id + date stamp. Would someone tell me a hack I can
use to support this?

Delete All action
Hi,
What is the best way to delete all members of a model?
For example I have a tasks model and want to put a link in that will
delete all tasks at once. Something like,
@tasks = Task.all
@tasks.each { |task| task.destroy }
Do I need another action for this, and what should the link to it be?
cheers,

walkthrough: Rails 2.0 startup process
I haven’t found a complete big-picture walkthrough for the Rails
startup process when I looked for one recently.
There are some really useful resources about this but they are for
Rails 1.2 and each of them only covers certain parts of the process.
Thus, I’ve taken some notes while reading to the Rails code and
compiled the following guide from them.

Serialized object behaves weird

I got a class named EinsatzFilter which I serialized to session. Before
saving to session it works afterwards I keep getting the message:

Delete_all causes a deadlock on MSSQL database ???
Hi all,
When i use the ''delete_all'' function to remove a few rows from my
database, it causes a deadlock on the sql server. The delete seems to be
successful, it then redirects to the ''view'' page, and the record does
appear to be deleted as far as the ''view'' rails page shows.
BUT if i go into sql query analyser, i can''t do a

update_all not changing updated_at
Hi everyone-
Model.update_all works and changes the records, but it''s not changing
the updated_at field. Am I doing something wrong or is this by
design?
Thanks,

Edge Rails namespaced routing
Hi,
I was wondering if anyone came across a similar scenario when working
with namespaced routes with edge rails.
Consider an application with controllers customers and products that
also have other resources.
map.resources :customers do |customer|
customer.resources :notes
customer.resources :tags
end
map.resources :products do |product|
customer.resources :notes
