linked table confusion
placement.rb
has_one :client
has_one :case_manager
client.rb
belongs_to :case_manager
has_many :placements
case_manager.rb
has_many :clients
has_many :placements
I am trying to create a view file for placements.
I can pull columns from clients table in this view by using...
<%= @placement.client.wholename %>
but if I use
<% @placement.case_manager.wholename %>

Lookup from related tables
I have been working on this for 3 days and haven''t been able to solve
it.
I have 2 tables...
clients
belongs_to: case_managers
case_managers
has_many: clients
When entering new clients, I need to have some type of select box that
allows me to pick the case_manager (by name) so that the ''id'' field from
the case_manager table is inserted into clients.case_manager_id

DRY methodology
because I am a grasshopper...
Now that I can sort my ''list''...is there a logical way of not repeating
myself to having essentially the same list view with multiple sorts?
i.e.
def list_cl
# ordered by clients last name
@placement_pages, @placements = paginate(
:placements,
:include => [:client],

everyone else but I haven''t been able to find the answer to. i''ve
tried searching through the forums and the api pages and haven''t found

(beyond putting in the relevant foregin_id attributes)

foreign keys on migration
I have reached a development plateau and now want to integrate some of
the rails niceties that I passed over to get the system online.
I am fooling with migrations. I am using postgresql. I put in my
migration script (at the end of the ''up'' method, the following raw sql
code...

Validations continued
I simply can''t figure this out. I have been reading and re-reading Agile
book and wiki.rubyonrails.org - all sorts of validation methods and
still, it doesn''t work.

Lookup pattern in Ruby
Hi folks,
I''m curious how a lookup with a large group of values would be handled
in Rails.
For example, I have a (contrived) AnimalType filtering a list of many
Animals--more than can be presented comfortably in a dropdown box.
Therefore I need to either redirect to another screen to select an
animal (returning after the selection is made), or show a dialog--modal
or otherwise--to

send_file VS. send_data (performance)
Does anybody know if there is a big performance/time cost difference
between these two methods of serving a file:

send_file "test.png", :type => ''image/png'', :disposition => ''inline''

pmt
I am working with the pmt function in the {mnormt} package, and i am getting
negative values returned. the following is an example of one of my outputs:
pmt(x = c(3.024960, -1.010898), mean = c(21.18844, 21.18844), S =
matrix(c(.319,.139,.139,0.319), 2, 2),df = 42)
# -6.585641e-18
Any help on why i'm getting negative numbers would be very much appreciated.
THanks!
