Repost - Do dynamic finders work with legacy schemas?
Hello everyone,
I have another question related to a legacy schema I am working with.
Do dynamic finders work with legacy schemas in general? The schema I am
working with uses hungarian prefixes for column names. For example fOpen is
0 if a bug is closed and 1 if it is open (type smallint). When I try @bugs
= Bug.find_all_by_fOpen(1), I get the following exception:
undefined method

Problem running unit tests
I am running Rails 1.1.2 with Ruby 1.82-15. My database is Postgresql. I
haven''t had any problems generating models, migrations, using scaffolds, and
generally building and using my application, but I haven''t been able to get
testing to work. I initially just ignored the problem and kept developing,
but would like to add proper testing from here on out.

Versioning the contents of a table as a set
I am looking at using acts_as_versioned to manage revisions of data in
several tables in my application. However, the default behavior of
acts_as_versioned appears to apply to individual rows within a table. The
tables I want to version are complicated lookup tables and what I really
want is to version the entire contents of each table as a single set.

Hello Everyone,
I have been reading this mailing list for a while and am impressed with the

Which database to choose for a new Rails application - MySQL 4.1 or 5.0?
Hi
I''m choosing a database for a new Rails application. I pretty much
ruled out PostgreSQL, since despite good reviews of the database
itself, it seems it has countless issues with Rails (for example: in
recent releases migrations don''t work, and unit-tests fail).
So I should now choose between MySQL 4.1, which as I understand enjoys
widespread popularity - perhaps the most

Migrations don''t really support transactions
I read in various places that although migrations aren''t transactional, all
you need to do is wrap you migration method in "ActiveRecord::
Base.connection.transaction do"
to make the self.up or self.down transactional. In my experience (Rails +
PostgreSQL), this doesn''t work very well. If my migration hits an
exception, any tables that were touched remain modified.

OT -- A "HOWTO" is a guide not a question.
This is way offtopic, but I''ve seen this several times recently and
it''s annoying me.
If you put "HOWTO" in your subject that means that you''re posting a
guide on a particular topic. It doesn''t mean that you''re asking a
question about "how to" do something.
It''s not like it''s a crisis, but it screws up searches

Reduce Number of Queries When Using ActiveRecord
I have a controller method called update_all that grabs parameters for about
30 form fields and saves them to the database. My current code looks to see
if there is a string in params[] for each form field (two fields for each
SelfEvaluationItem) and saves the updated self_evaluation_answer if a string
is available. Since this is iterated code, I am almost certain that this
generates 30 or so

How to display a welcome page
Wow, I can''t believe that after a few weeks of playing around with Rails I
got stuck on something that seems like it should be really simple.
How do I display a default welcome page for visitors who are not logged in
and send logged in users to the appropriate controller. I am using the
login_engine and the user_engine.
The two methods I have seen looking at sample code are to stick a

string to date/time?
Hey All,
Anyone know of a library for parsing "human" dates, like "this friday"
or "2 days ago"? I used to use strtotime in php, but starting from
here;

and doing lots of googling, I haven''t been able to find anything
similar for ruby. I know of javascript solutions to this, but I''d

[BUMP] conditional require? conditional action code?
Greetings all.
I have some controller code that uses win32ole (only available on
windows). This code is now solid, and I''d now like to resume
development on (any) other OS(grin).
But alas, the controller bails because the OS specific library can''t
be found.
Can I conditionally specify action code compilation (and a require
''win32ole'') based on OS or

Getting column value from lookup table in HABTM relationship
I have a HABTM relationship between my agents and listings tables. Each
listing can have many agents and each agent can have many listings. In
the agents_listings table I have a column called ''is_primary_agent''
which denotes if the agent is responsible for the listing - only one
agent can be primary.
At the moment I use this in my listing_controller''s view

proposal for "strict" versions of subsetting operators
I'd like to propose adding "strict" versions of the subsetting operators "[", "[[", and "$" to the R language. These strict versions would be intended for use in programming rather than in interactive use. They do not perform any form of partial string matching or opportunistic simplification such as dimension dropping by default. They allow more

enforcing special behavior of child rows in HABTM
Hi,
I have a scenario where a doctor can have one or more specialties.
For each doctor, one and only one of her specialties can be designated
as primary.
So I have tables called doctors, specialties, and doctors_specialties,
the last of which has a boolean is_primary column.
The doctor model class specifies that:

Postgresql and ActiveRecords problems
Hi all. I have a problem with postgresql PK columns and ActiveRecord.
The error is: PGError: ERROR: null value in column "item_id" violates

radrails gone mad
Hi *,
I have been using radrails as an IDE for awhile now and we were getting
along just fine - but recently it has just gone totally postal?!??
I created a new rails app - when I click to expand the folders there is
no framework in place, just the root folder of the app.
To add insult to injury two weeks of work also just disapeered - I kid
you not just gone without any deletion on my part.
