ActiveRecord::StatementInvalid error
When I try to run my webserver in the production environment I just

cached-model broken with Rails 1.1
It looks like cached-model is broken again under rails 1.1. Can anyone
confirm? Note that the exception below indicates it''s trying to treat
CachedModel as the class name of the model, rather than using the proper
class name (which is Entry in this case, and the table called entries).
This is a model using Single Table Inheritance and acts_as_tree, and
worked just fine under 1.0 and

habtm confusion
Hello friends!
I am trying to make a database that will have a group of people set to
committees, and a person can be in multiple committees, and a committee
obviously has multiple people. The people are senators at my
university. These are my current models:

Boolean circles..
Hi,
This is just kindof a RoR question, but since you all potentially do
the same things as I do, I thought I''ll ask here..
Im trying to use the boolean type in the database. Migrations is no
problem, it even converts the 0/1 values from my import CSV to false
and true.
However, I cannot make the :conditions part of a find work:

SQLite3::SQLException: id may not be null
I am getting the following error using sqlite3. If I ran the same query

Sqlite3, in-memory db and rspec_server
Hi everyone.
I can''t get the above(subject line) combination to work. If I use a
standard sqlite3 file db for the test db, and spec_server all the
specs on my models pass. If I use an in-memory db for the test db,
script/spec w/o spec_server, they all pass. But if I use in-memory and

BackgrounDRB and Sqlite3 / Autotest / Memory_test_fix Issues
Hello all.
I am using BackgrounDRB with "great happiness and joy", however, I am
running into one problem in that when I am running my tests with
autotest using Sqlite3 3.3.17 I am getting
"ActiveRecord::StatementInvalid" exception inside of the
sqlite_adapter.rb:360 which is checking for an empty structure.
I thought it might be the version of Sqlite, so I upgraded to 3.3.17

ConnectionNotEstablished when using connection on AR::Base abstract subclass
I''m using AR outside of Rails and calling establish_connection on an
ActiveRecord::Base abstract_class subclass (to protect my connection
in case anyone else is using AR). It was working just fine with AR
3.0.9, but I recently attempted to upgrade to AR 3.2.2. Now, when I
hit a "nested" query from a has_many, I get a

SQLite primary key schema
So after successfully getting the test SQLite db to run from memory, I
tried running some tests but found that somewhere in the schema
translation from Postgres (my devel database) and SQLite Rails fails
to properly set the ''id'' column, which breaks all kinds of things.
Take as an example my ''users'' table. In Postgres the schema is

abstract_class... what exactly does it do
Hi,
Does anyone know much about abstract_class? Does it actually prevent
instances of the class from being created? Does it disable certain
methods? I already know what it''s for, but I want to know what setting
self.abstract_class=true actually does.
The reason I ask is that I want to use it for a slightly unorthodox
purpose. I want a class who''s only attributes are its

Inheritance problem in model
Hello,
I''ve got a problem with the inheritance as soon as I try to use it in a
model.
I''ve got plenty of items which can share a lot of code, so I created a
class "Item", which inherits from ActiveRecord::Base, but because it''s
not a "real item" but an interface, I set it abstract (writing
abstract_class? method).
Then I have all the differents

SQLite in-memory
I left ":memory:" in database.yml for testing and the most simple
tests in the Agile book do not work (see trace below for test_truth).
Since that''s what comes with the distributed database.yml I suppose
it''s me doing something wrong.
Did someone get SQLite ":memory:" working? How does it grab the schema?

Model with self.abstract_class=true allows save method call
I think this is a bug.
I declared a model with self.abstract_class = true and then tried to
call save on it and it attempted the save. I think this should raise a
"method not allowed" exception of some sort.
Where is the Trac system that I would use to report this?
Thanks,
Wes
