Form magic
Didn''t know what else to call this subject, sorry.
Anyway this is more a general discovery question then a coding one.
Is it possible (and I already know it should be) to create forms where
depending on a particular choice in one select tag, one or another
select tags would be presented in the form.
As an example, a shopping site , where a dropdown has options of:

Special ruby language for describing sql conditions
I was brainstorming today about a smooth way to define conditions in an
sql query, when the numbers of attributes increase, so does the uglyness.
So instead of passing a hash, I thought you could specify the conditions
directly in code.
I hacked together some example code which actually turned out to work.
The result is concise and pretty beutiful.
def search(params)
Ad.find(:all) do

using conditions
Hello guys,
I''m pretty new to using AAF and am having a slight problem with using a
condition. I have the following code
@results = SupplierProduct.find_by_contents(params[:search], :conditions
=> [''area_id = ?'', @area])
and it seems the condition isn''t being applied. Does anyone have any
pointers?
Cheers,

validates_uniqueness_of: passing a method to :scope
I was wondering if anybody knows an easy way to pass a method name as
the scope option to a validates_uniqueness_of validation on a AR model?
For example, I have nested models a bit like:
class Survey
has_many :areas
end
class Area
belongs_to :survey
has_many :questions, :order => ''position''
validates_uniqueness_of :position, :scope => : survey_id
end

puppet 3.1.1
I''ve written a puppet module for configuring qpidd brokers. I have

I can successfully configure broker artifacts (exchanges, queues, bindings,

Now I''m trying to understand how I can do the same thing from inside a ruby

passing hash from controller to view and pluralization?
hi,
i have 2 tables (counties and towns). counties has_many towns and towns
belong_to counties.
now my question:
i thought i would need to do is say @counties = Counties.find(:all).
should that not return to me all counties in the counties table WITH all
towns associated with each county?
in my view i was getting error when doing this
if(counties.has_towns?)
saying undefined has_towns

Coloring counties on a full US map based on a certain criterion
Dear Rers,
is there a way to color counties on a full US map based on a criterion
one establishes (i.e., all counties I assign the same number should be
the same color)?
I explored a bit and looks like the package "maps" might be of help.
library(maps)
One could get a map of the US: map('usa')
One could get countries within a US state: map('county', 'iowa', fill

Does HABTM support non "id" FKs?
Quick question. Say I have a geographical database with counties and zip
codes where counties have and belong to many zip codes.
zip_codes (id, zip_code)
counties (id, name)
When I create the association table, the Rails way says to do the
following: counties_zip_codes (county_id, zip_code_id).
However, given that zip_codes.zip_code is itself a candidate key, I
would much prefer to do the

Map of UK Counties - to use in R
Hi,
Can anyone help me with either of these:
1) Map of the UK counties that I could use in R?
2) How could I use an existing map for example, a map from here
http://www.itraveluk.co.uk/maps/england.html - in R. I need to use a UK map
to plot locations on it by lat & long.
Would appreciate help on any of these.
Thanks,

observe_field submit behavior
I am using observe_field on a number of multi-selects and checkbox form
elements whose values would normally come in as arrays on a normal
(non-Ajax) form post.
I understand that by using the :with => ''name'' I will get name=value in
the request.raw_post however if the field I am submitting has mutliple
values and the name is of the form ''name[]'', I get

counties in different colours using map()
Hi,
I would like to plot a map of US counties using different colors. map()
seems to be the function to use, e.g.
library(maps); map('usa'); map('county', 'colorado', add=T,fill = T,
col=c(1:5))
plots Colorado counties using colours 1 to 5.
However, I want each color to represent a certain value - a value to be
picked from a data frame.

R equiv to proc gremove in maps package
Is there an R equivalent to SAS's proc gremove? You would use this procedure to combine the units on an existing map, for example to build a map of Metropolitan Statistical Areas (MSAs) from the [US] counties dataset where the internal boundries surround the MSAs (which are groups of counties) rather than the individual counties. I can imagine the mechanism would be to find and erase the

Package "maps": what is the name of county # 2395?
I am using "maps". I am running the following code to get this list of
all the counties:
map('county', plot=FALSE)$names
In the output, all counties have first the state listed and then,
after a comma, the name of the county.
However, county # 2395 (State = south dakota) has no county name.
Anyone knows what this county is?
Thank you!

has_many :through with a polymorphic join
Hi,
Four tables: users, user_counties, uk_counties and us_counties.
Each user has many counties, and each county has many users, so I
decided to make user_counties a polymorph, so it can have counties
from different countries (each country requires a completely different
set of tables with a completely different set of properties, that''s
why there''s one table for uk_counties and

Coloring Canada provinces (package maps?)
Dear R'ers,
I am wondering what is the smallest geographicterritorial unit
available for formatting in Canada. Provinces?
I know that in the US it is the county so that I can color US
