Strange memory issue
Like most, I have a test and a production env. Both are CentOS 5, Ruby
1.8.6, Rails 2.0.2, MySQL 5, and Apache. Both were setup using the
same procedure. Except for the hardware (test: Intel, prod: AMD) and
memory (test: 512M, prod: 1G), both systems are essentially the same
right down to the Rails env. Unfortunately, memory usage is very
different for each.
The test system has 2 mongrel

So how can I rewrite my app without using with_scope?
So, I hear that with_scope is going to be deprecated.
Which is a bit of a shame, given the stuff I''ve been writing recently.
I have a CMS with multiple clients. A ''client'' is essentially a
company, with multiple users. Content on the site belongs to a client
- content could be messages, images, schedules, etc etc. People
belonging to one client should not be able

Serialized object behaves weird
Hi!
I got a class named EinsatzFilter which I serialized to session. Before
saving to session it works afterwards I keep getting the message:
"undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from
ActiveRecord::Base inherited class.
Code:
class EinsatzFilter
include ApplicationHelper

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

ActiveRecord Limitation (Advance)
Or is it ?
Need to be able to :-
@search =
Form.find(:all, :include=>[:form_type, :form_type_items], :conditions=>....)

Current Models:-
Form
belongs_to :form_type
FormType
has_many :form_types
has_many :form_type_items
FormTypeItem
Belongs_to :form_type

STI with_scope on parent - bug or feature?
Hi,
It seems that setting a with_scope on the parent class doesn''t do anything
MyClass.with_scope(:find=>{:conditions=> ["somecol = ?", ''val'']}) do
@ext_pages, @ext_rows = paginate :my_extended_class, {
:per_page => 13
}
end
# this doesn''t generate WHERE somecol=''val''

ActiveRecord::Base#update_all expected behaviour
Hi
I noticed that if in my code I use the following:
Photo.update_all("title = ''Ruby rocks'' ", "id IN (#{@photo_ids})")
All my objects are properly updated but none of the filters/callbacks
are triggered. Is that what''s expected?
I have a before_update filter set on the Photo class and it gets
totally ignored, I guess the only way to solve this

Modifying "Find" to always add a condition?
I''d like to always add a condition to any version of "find" (e.g.
Thing.find(), Thing.find_by_name(), Thing.find_by_whatever) so that in
addition to whatever conditions are set, an additional condition is set
:conditions=>"user_id=#{current_user.id}"
I''d like to make sure that a user only sees/edits/creates entries in the
database that have the user_id

Migration Bug?
Please tell me I''m just confused, but this is very strange.

Question on application/database design for a application port to rails
Hi all
I am hoping that the experience and knowledge of this ''list'' will be
able to help me out with some design decisions I have to make while
porting a desktop app to rails.
Here is the scoop:
I am in the design process of porting a fairly large client/server app
to rails. Average data set is about 200 MB per database/server.

Anything like with_scope for ActionController?
There are areas of my application that "want" to use a url structure
like
domain/<human_readable_param>/<Module>/<Controller>/<Action>/<Id>
Please note that the human readable parameter I need to inject is NOT
related to the <id> being used by the action/controller pair. It''s
identifying a container object whose contains are operated

Polling is REALLY slow
I''m having some trouble with using brb for polling for work. Basically, what
I want to do is update the state of a record and have brb notice and start a
process. I do not want to call ask_work for each process because there may
be several places where the object''s state is changed, and I only want to
process once. Plus, I can schedule things better this way. My first

undesireable lazy loading
Hi,
My work with Rails has been fairly straightforward, until yesterday...
I''ve encountered rather a peculiar problem that I''m not able to solve
myself as a rails-newbie.
The model code looks like this:

end
class UserVote < ActiveRecord::Base
belongs_to :user
belongs_to :link
