Does anybody know why activeRecord is not built on top of ruby-dbi?
Does anybody know why activeRecord is not built on top of ruby-dbi?
I am curious about the reasoning behind the decision.
Was it performance? Complexity? Databases support, ease of
installation or something else.
Let me know if anybody knows why.
Thanks
Diego

Does anybody know why activeRecord is not built on top of ruby-dbi?
I am curious about the opinionated opinion behind the decision.Was it
performance? Complexity? Databases support or something else.
I recently used Ruby:dbi and liked all the metadata that comes with the
data.
Performance looked good but I didn''t benchmark it so I don''t know which one
execute faster.
If I am not wrong Ruby:dbi offers true parameters binding which would be
nice

ActiveRecord 1.13.2 -> 1.14.0 breaks Postgres connectivity
To Whom It May Concern:
I have an ActiveRecord-based application (non-Rails). Life was grand
until I upgraded ActiveRecord yesterday, after which point I was getting
TONNES of these errors from my app and in PostgreSQL''s logs:
FATAL: terminating connection due to administrator command
According to Google searching, this happens when an external process

Getting at DBI connection via ActiveRecord connection
I have a standalone batch program that is going to move data between two
databases.
I am taking advantage of the AR connection semantics in database.yml to
get connections to these two DBs. But I want to do all of my DB access
at the DBI/DBD level for performance reasons.
I am having trouble getting access to the underlying DBI handle so that
I can prepare SQL statements, execute them etc.

SQL Server via DBI/ODBC configuration
I have followed the cookbook on http://wiki.rubyonrails.org/database-support/ms-sql
but am having problems with the rails part. I can connect to the
database using sqsh so I think all the freetds plumbing is good. When
I try to connect to the db with a rake db:migrate or just using script/
console I get this error:

Ruby DBD::Proxy
I noticed that some of the ActiveRecord adapters depend on ruby-dbi.
I''ve just started to play with the ruby-dbi database driver DBD::Proxy,
which allows me to connect to other ruby-dbi drivers running on other
operating systems.
What seems more practical, developing a ActiveRecord database adapter
for DBD::Proxy, or would you just target a specific database, and just
depend on

Extracting a connection out of ActiveRecord::Base
Hi
I''m trying to use the Typo wordpress converter script, but it requires
that the wordpress database is accessible over the connection to the
Typo database.
To get around this, I''m trying to use ActiveRecord::establish_connection
(...) to get a connection object to run the raw SQL queries that Typo''s
wordpress converter uses on. It doesn''t work with Ruby

controller before_filter issues
Hi,
Some controller filters:
before_filter :require_logged_in, :only => [:create, :new, :confirm]
before_filter :init_players, :only => [:create, :new, :confirm]
The first one, you guessed it, redirects a user if he''s not logged in.
Now when I hit this page and I''m not logged in, the 2nd filter gets
executed and throws an error, because it depends on the user

inserted_at seems buggy in production mode?
Hi,
I''ve got a table with an inserted_at column. When I insert a record it
automatically injects the current date/time, all is well.
Then when I insert a second record, it uses the exact same timestamp
that is used in the first record.
This behavior only seems to occur in production mode. When I restart the
server, the problem goes away but then immidetatly occurs again on the

how to create a command line script that acts on a model?
Hi,
I''m looking to create a ruby script that loads a bunch of records and
manipulates these. Where do I start?
I got this to begin with:

But it complains about a DB connection. How do I set this up?

ActiveRecord: table name with spaces?
Howdy.
I''m trying to work with a legacy SQL Server database where some of the
table names have spaces in them.
I''ve done set_table_name "tablename with spaces", but I can''t get
find(:all) to work. I get the following error (because apparently
it''s not putting [ ] around the name as is required for SQL Server for
names with spaces.
