Problem with plurals, migrations?
Hi,
Ruby 1.8.4
Rails 1.1.4
Windows XP Pro
I''m hitting an issue with migrations that I suspect relates to
pluralization. Here''s the migration:
class Hardware < ActiveRecord::Migration
def self.up
create_table :hardware do |h|
h.column :vendor, :string, :limit => 32
h.column :model, :string, :limit => 32

How to disconnect to a database????
Hi,
We have experienced some problems with
ActiveRecord::Base class of Ruby-Rails. We are
building a web-application based on the Ruby-rails
framework and the web-application needs to access to
difference databases, so we do not pre-define our
database accesses in the database.yml file. In fact,
we are using the
ActiveRecord::Base.establish_connection() to connect
to our database, the function

Migrate default now()
I want to set default value to current time of database:

def self.up
create_table :users do |t|

t.column :created_at, :timestamp, :null => false, :default => ''now''
end
end

On postgresql, it is converted to:
created_at timestamp NOT NULL DEFAULT ''2006-04-25

[Tip] Introspection to determine if a column may be null
I still want to get this into Rails for all connection adaptors, but
for now I''ve hacked my own addition on for just PostgreSQL.
The following code extends every Column object returned by
MyModel.columns to support a new #required? method, which indicates if
the column may or may not be null.
The following is a huge hack - suggestions on a cleaner way to add this
functionality

Can't use models in migrations
Hi there,
This always used to work for me... but not now. I want to blame Rails
1.2 but I''m sure its not.
I can''t use AR models in my migrations. To make sure its not just my
dodgy code I tried to do the same with a well known plugin..
acts_as_versioned.
A migration such as the one below (taken from acts_as_versioned) is
giving the error

Helps!!!!! Rails database connection guru needed!!!!!!!
Hi,
I really need help to understand what is happening
while Rails connect to a database, (we area actually
using postgresql, so my example will be with
postgresql) What I understand is Rails is able to
connect to different DB. Actually, this is what we
want, and we have made some tests, everything is juste
fine. However, all these tests lead us to some
important questions that we did find the

Migrations - add_column :default=>true, :null=>false
This seems pretty brain dead:

Error: ERROR: column "notify_on_create" contains null values

Why doesn''t Rails set the new column to true, as it''s supposed to
default to? I tried :default=>1 as well (same

Migrations: column option "offset"?
Hi,
On the wiki
http://wiki.rubyonrails.com/rails/pages/UnderstandingMigrations it says:
Valid column options are:
- limit
- offset
- null (i.e. ? :null => false? implies NOT NULL)
- default (to specify default values)
I was wondering what the purpose of the "offset" option is. And after
looking at the API at

Patch for Element.Class - wrong regexp
Hello,
I noticed (due to a recent post by Martin Honnen to clp) that
Element.Class uses wrong regexps for its operations.
E.g., Element.Class.has() will find "classA" in "classA-foobar"
I also changed the interface of .has() to the more general one used in
.has_any()

Get first class name
I have a situation where I need to get the first class name of an
element.
Element.ClassNames() returns an object not an array...
Object.values() will turn it into an array, but the API Docs say that
the order of the resulting array is browser-dependent.. So for my use
is no good...
So I am using:
el.className.split(" ").first();

rails ignoring the migration file
I have a mysql database that I am trying to use migrations on. The
problem that I am having is that when I create a blob field in my
migration file like so:

rails changes it to this in the schema:

mangle ActiveRecord
Dear Gurus on Rails!
How do I change the behaviour of one method in
ActiveRecord::ConnectionAdapters::SchemaStatements ?
Full story:
I''d like to mangle
ActiveRecord::ConnectionAdapters::SchemaStatements
so when it creates a new sql table, it also (optionally) creates my
created_at, deleted, key_id, session_id etc columns that I use on basically
all tables.
It would not be DRY to repeat
