Aggregating data from two data frames
Dear all,
I'm working with two data frames.
The first frame (agg_data) consists of two columns. agg_data[,1] is a unique
ID for each row and agg_data[,2] contains a continuous variable.
The second data frame (geo_data) consists of several columns. One of these
columns (geo_data$ZCTA) corresponds to the unique ID in the first data
frame. The problem is that only a subset of the unique ID

Memory Issue while looping through CSV file
I have a site on a shared host at TextDrive. I have an import process
that imports a CSV file into the database using a ruby script executed
using script/runner. TextDrive has a memory limit which I am hitting
and the process gets killed. I get through to about 400 records before
it dies. I guess each time I instantate a new object for each record I
am using more memory but thought I was using

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

Sorting by computed temporary field
Hey all,
I''m rather new to Ruby and Rails (and not great with SQL), but I''m

Validation errors in has_one/belongs_to relationships.
I have two objects, QuoteInput and Insured.
QuoteInput has one Insured and Insured belongs to QuoteInput.
I don''t understand what I''m seeing.
I assign an Insured to a QuoteInput. The Insured object has invalid
data.
I call save! on the quote input. QuoteInput has no validations.
I expect two things to happen - 1) an exception should be thrown,

Rspec not loading fixtures
I am taking over a code base and am trying to run the tests. I am
somewhat new to RSpec so this might be a trivial problem.
Basically I can tell that the fixtures are not getting loaded. All 100

But I don''t know why. Below is the code, with my narrative with ***

PGError: duplicate key
I''m running a rails 2.3.5 / ruby 1.8.7 / postgresql 8.4.2 app and have
just run into a curious problem.
I have several tables that are initialized with data from csv files
and I''ve noticed that, when I try to add new data to any of these
tables via Table.new I get a PGError on duplicate key.
For example:

So I''ve knocked up this little function to use CSV files instead. Now

Best way to split forms into steps?
I have a form with about 30+ fields, which the client is wanting to
separate into 3 pages/steps - just wondering what is the best way to go
about this, specifically remembering data entered, from one page to
another, and making sure the various bits of data are validated
correclty, error messages outputted etc etc...
is there a best practice method for doing this?

Column aliasing in ActiveRecord?
Anybody know of a way to alias a column in ActiveRecord such that you
could reference it via a different symbol in your view for view
purposes?
Like my column is named X but I want to display it as Y and maybe I have
an accessor named Y set up on the model so that when I "call" Y from the
view (and controller?) I''m actually manipulating the column X?
Hope that makes sense.

Below is my attempt to include direct and nested associations.

reading VERY large binary files
Hello,
I am trying to read in elements out of a very large binary file ... the
total file is 4 gigs. I want to select rows out of the file, and the
current procedure I run works but is prohibitively slow (takes more than

accomplish this?

Geodata SQL statements with multiple results in the controller
Hi Everyone-
In my project I need to take a zip code and get all the schools within
the selected mile radius of that zip code. In addition I will need to
check to see if the user selected any other items to add to the
search.
My problem is the geo code will return multiple results and I need to
get that result into the final sql string.
The flow is this:
