handle multiple lists: move an item from one list to another
How do I manage multiple lists?
This is what I need. Sometimes an item needs to be moved from one list
to another.
class Item < ActiveRecord::Base
belongs_to :group
acts_as_list :scope => :group
end
class Group < ActiveRecord::Base
has_many :items, :order => "position"
end
Now, sometimes, I may need to change an item from one group to another.
But when I do that,

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

Bug? find_by_id(nil) returns object just created
Tried to submit a ticket in Trac, but it reported an error...
Doing a Model.find_by_id(nil) after creating an object of type Model returns
that object -- and the next time, returns nil. It should always return nil.
For example,
Step 1. Create an object:
>> Foo.create(:name => "bar")
=> #<Foo:0x2aaaac3ade20 @new_record=false,

Easiest defense against SQL injection in object creation?
I''ve been scouring the web for suggested Rails defenses against SQL
injection, but I haven''t found much on the object creation part.
Certainly using attr_protected, etc., is a good way to prevent unwanted
fields from being modified on the new object (if you''re passing a hash
as creation parameters), but what about escaping the POSTed info before
saving? Couldn''t

attr_accessible on some properties + attr_protected on others makes class 'open-by-default'
(I posted this as a bug in GitHub
(https://github.com/rails/rails/issues/7018), but then someone there told
me I should post it here, so here it is.)
If you set attr_accessible on some properties in an ActiveRecord-descended
class, and then attr_protected on others - the class becomes ''default-open''
- if any properties are missed or added later, they will be accessible by

Permission denied using mount.cifs
I'm having a strange problem mounting a share from a Windows 2003 server
using cifs:
mount.cifs //osirus.ficticious.org/inetpub /inetpub
-ouser=transfer,pass=dkfhjdjskd
It comes back immediately with:
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
However, the command below works. (abeit with about a 15 second wait
before it comes back):

Strange Problem With Unwanted, Transient Caching
Hello,
I hope somebody can explain to me what''s going on here because I''m
baffled!
In a controller''s action I want to create a new order for a
customer. Because I post back to the same action (not RESTful I
know, but that''s for another day) I use code like this:
def edit
@order = Order.find_by_id(params[:id]) || Order.new

find_by_id vs. find in postback action

book.
Here is the default code given:

if request.post?
@recipe.attributes = params[:recipe]
redirect_to :main_url and return if @recipe.save

acts_as_list with scope : position update problem?
Hello,
I''ve tried to set up a class with acts_as_list with a scope argument
that restricts a list to records with the same foreign key.
For example :

`id` int(11) NOT NULL auto_increment,
`name` varchar(255) NOT NULL default '''',
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=3 ;

'redirect_to' taking infinite loop.

why it is going into infinite loop?

params[:driver_id] == 0 ) ? nil : Driver.find_by_id( params[:driver_id]

find_by_id(nil) does not always return nil
I have a model named User. When running this application from the
console I can call User.find_by_id(nil) and it returns nil. When running
this application during testing or through WEBrick or Mongrel calling
User.find_by_id(nil) returns the newest record in the database. But it
only does this the first time you call it with nil. The second time you
call User.find_by_id(nil) it returns nil.

DateTimes get converted to Dates in XML-RPC????
Hi all -
I have written an XML-RPC app using action-web-service. Mostly works
well. Except I just noticed that my :datetime types are coming back as
:date types.
That is, when in the console I query the record via Foo.find_by_id(123) I
get back actual datetimes. If I then do it via XML-RPC, fetching that
same record I get back dates (ie. hour/minute/second are set to 00:00:00)
Any ideas?

Question: coding protected methods
Apologies first, because I need to ramp up on Ruby and coding Ruby in Rails,
however it''s my 3rd day with this beast :) so I''m asking :
When I added protected methods to the model before it was like:
protected
method....................
end
Would this be a valid way to write a protected method as well ?:

spec''ing shared controller methods
I want to isolate and spec methods that are shared by controllers,
and live in application.rb.
Whereas I usually also provide examples in individual controllers
that use these methods, not necessarily all the edge cases and I''d
like to isolate the examples.
This is the approach I''m taking (thanks to bryanl for suggestions and

Validating that a foreign key is present and ok
How do I validate that a model object''s attribute is a valid foreign
key? The problem is, I can''t check if the attribute is a valid foreign
key if the attribute doesn''t even exist.
For example, every employee must be in a department. In the following
code, if an employee''s department_id is not present then
Department.find_by_id(department_id) might cause

right usage of bdrb
Hi,
i''m going to implement a syndication-service, which will get lists in

a full hour.
So i thought to build 4 Worker. One for checking which feeds to

URL based on acts_as_tree using routes
Hi There!
I''d like some feedback before I try to implement some funky rails
routes based on an acts_as_tree model.
I have a Page model that acts_as_tree. I''d like the URLs to look
something like this:
http://localhost/about-us/staff/jeff
or, another example...
http://localhost/what-we-do/products/our-great-cms/features/faqs/
So, as many sub-nodes the user creates,
