having a problem with acts_as_state_machine
Hi all:
Below is s a dump from script/console in development env.
Am I not supposed to be able to find the record later and use the
state machine functionality, or have I missed something? Thanks

Active Record save doesn''t save! (more detail - is this a bug?)
I got it to work by changing
scheduled_end_date= nil
to
self.scheduled_end_date= nil.
I believe these statements should be equivilent.
I don''t know Ruby/Rails well enough to know when, if or why that should
matter. Can someone educate me please? I want to believe this framework is
ready for production work, but silently dropping data is a very big
problem. I expect that I''ve

Active Record save doesn''t save! (or throw an exception)
PLEASE help me - this is making me insane.
Can anyone suggest any reasons for this behavior? It occured previously,
then went away and is now back.
In Task.rb (where task is an active record subclass)
def clear_schedule
puts "clearing schedule for task"
scheduled_end_date= nil #reset the
scheduled end date

Breakdowns in has_many abstraction
I discovered an interesting aspect of has_many behavior that I''m
struggling to work around. I''m not sure if I''m doing something wrong,
or if it''s a legitimate bug, or if it''s an inherent part of Rails that
I just have to learn to deal with.
It boils down to these two problems:
- changes in collection objects (i.e. models that belong_to a

datetime fixture format for Mysql 5.0
Hi All:
I develop on several machines, most have Mysql 4.* and one has Mysql
5.0. On 4.*, the following erb for a fixture works fine:
updated_at: <%= 1.days.ago.to_s:db%>
But fails on 5.0. I had a similar deal when I had date fixtures, and
switched forrmats so that both 4.* and 5.0 were happy. is there
to_s:db_works_for_mysql_50() ? or similar?
Thanks

find_by_sql column ordering defect?
Hello.
I have a program that accesses a metadata (translation) table for column
names as well as the ordering of columns for a specific model. Also in
there is a collection of bool options such as column_visible_on_form,
column_visible_on_screen_quicklist etc. The idea is that our customer
can specify to a certain extent how their layout/user interface will
appear.
To accomplish this, I use

Can''t get select helper to populate dropdown w/default value
Guys,
I searched this forum and found plenty of people having this problem,
but I didn''t see any definitive solution. Usings Rails 1.0.
When I edit an existing record, I can''t get the basic "select" helper to
display the current value contained in the field of the record. All of
my other (text) fields populate correctly with current field values.

Help with basic loop
The loop is correct, you just need to make sure that your result is computed
and stored as the n-th element that is returned by the loop. Pick up any
manual of R, and looping will be explained there. Also, I would recommend
that you draw a random number for every iteration of the loop. Defining the
random vectors outside the loop make sense to me only if they are the same
length as n.

namespaces
I'd like to control my namespace thoroughly, separated by task. Is
there a way, in R session, to introduce namespaces for tasks
dynamically and switch them as needed? Or, is there a combination of
load/save workspace steps which can facilitate this?
Cheers,

Optimize for loop / find last record for each person
I want to find the last record for each person_id in a data frame
(from a SQL database) ordered by date. Is there a better way than

if (history[i, "person_id"] == history[i - 1, "person_id"])
history[i, "order"] = history[i - 1, "order"] + 1 # same person

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

Design Question
I am sure some of you can give me an insight into this. This is more
towards the database design for the scenario below:
Say for example,
I have a person table and this person can have different address types.
One could be Home and the other could be say Office.
Should be model this
Table people
id
fname
lname
Table addresses
id
person_id
addr1
addr2
....
or
Table people
id
fname

Testing attr_accessible (and/or attr_protected)
