Sorting by computed temporary field
Hey all,
I''m rather new to Ruby and Rails (and not great with SQL), but I''m
developing a ride sharing app and would like to be able to sort on
something I don''t have stored.
I have users, events, and rides, each of which has a zip code. Events
have_many rides, and rides belong_to events.
When an event is selected, I''d like to be able to show a list of

How to test the model dependence ?
Good morning,
I''m new to rails and am having some basic questions in development. See
if anyone can help me with a test problem. I need to test if my model
"Procedure" is linked to the workflow. If not, the system must
acknowledge an error. Below is the code that is in the file test \ unit
\ procedure_test.rb.
require ''test_helper''

a better "should have valid associations"
This is pretty much the same as last time around, if you recall.
Thanks to Wilson for converting to the new form. I''ve added a few
lines. Basically, it iterates over your model associations and does
two things.
- First, just try to call the association. Usually fixes speeling
erors or other such silliness.
- Second, try to find a record with an :include on the association.

How to ensure deletes cascade to associated models?
I have the following models:
class Resume
belongs_to :resume_assignments
end
class User
belongs_to :resume_assignments
end
class ResumeAssignment
has_one :resume
has_one :user
end
When I delete a resume, I want to make sure that its associated
ResumeAssignment gets deleted also. Calling destroy_all to delete
some resumes doesn''t seem to do this. Is there an option that will

Trivial API question
I know - I like to futz. I''m thinking of changing the way I pass
optional arguments. This is from EventLog:
# Write an event to the event log
# Current way
el.report_event(
"source" => "foo",
"category" => 0x2,
"event_id" => 0x3,
"data" => "Warning! Danger Will Robinson!",

Possible problems with EventLog#write
Hi,
I''ve got EventLog#write and EventLog.add_event_source methods done.
Well, I *think* they''re done, but I can''t get the data (text) to work
properly, and I''m not sure if it''s a bug in my .mc file, the
add_event_source method, the write method, or just a goof in my test file.
The source, category and event id seem to be ok. However, the

Need for multiple acts_as_list

complete stumper: variable exists in hidden_field_tag, but nil everywhere else
This is a real mystery to me. I have an instance variable in a partial
that only gives its value inside a hidden_field_tag. If I try to use
the variable anywhere else in the partial, i either get nil or an
undefined error. The goal is to use the value of @event.id outside of
hidden_field_tag.
Here''s what works:

Anyone know how to copy rows?
Hey all,
I''m trying to write something that allows one to copy several rows from
a table and create new rows based on those rows. This will be used to
intentionally duplicate rows. Did I mention that I was having little
luck? I''m from a PHP world, but I''ve been getting really into Rails
lately.

[PATCH 1/2] drmmode: make event handler leave a note that there are stuck events
We don't really expect to have too many events in the queue. If there
are, then the algorithm we use isn't appropriate. Add a warning when the
queue gets very long, as it's an indication of something having gone
wrong.

help with ActiveRecord joins
I''m working on a fairly complex join query and could use a bit of advice
from more expert users of ActiveRecord.
I have an events table with quite a lot of data, with has_many relations
to categories, age_groups, and event_images. In my first naive
implementation, each event had a date, so to load all upcoming events
efficiently, I''d do:
