Migrating a Field to External Model
I have a model Product with an attribute ''brand''. Currently it is a
simple attribute, however, I am migrating it to a separate model

table. So far so good. Then I created a separate migration to
transfer the data. The up method

Migrations - add_column :default=>true, :null=>false
This seems pretty brain dead:
add_column :types, :notify_on_create, :boolean, {:default=>true,
:null=>false}
$ rake migrate
Error: ERROR: column "notify_on_create" contains null values
: ALTER TABLE types ALTER notify_on_create SET NOT NULL
Why doesn''t Rails set the new column to true, as it''s supposed to
default to? I tried :default=>1 as well (same

Counter cache like plugin for sum
Hi list,
Is there a plugin similar to counter_cache except for caching sums
instead of counts? The reason I ask is for performance and convenience
for reporting.

counter cache
Hi,
I have two models, employees and departments, and i am using
counter_cache to count the number of employees in a department.
This works great, but employees can change their departments, and the
counter cache does not get updated to reflect this.
Is their a built in way to do this, or do i have to implement my own
before_save hook
thanks

[Bug?] in tests, @foo.bars_count <> @foo.bars.count
Example: if a ''foo'' has 3 ''bars'',
bars_count == "0" # ERROR
bars.count == 3 # OK
It looks like a bug to me.

How to pass a collection to paginate?
There must be a better way to write this code:
@project_pages, @projects= paginate :project,
:per_page => 10,
:conditions => ["account_id = ?", account]
?!
If only I could pass the sub-collection
account = ...
@projects = account.project
to paginate, instead of letting it extract it with a find :all + sql
conditions

Parent Child together in input form
Hi all,
I understand how rails is supposed to work when dealing with one entity
input form.
However, when I have a relation between two objects (composition):
Customer(1) --------> (1)Address
How can you create a inputform where both the properties of a Customer and
Address can be filled in?

rake migrate ignores '':null => false'' on mysql
I wanted to add a login string column to an existing table
=> I created a migration :

remark: it shouldn''t work, as the table is not empty (=> ''login'' would
be null in the existing rows.)

rake craziness with Migrate as a dependency
Hi everyone,
For one of our projects we have a need to deploy and maintain a demo.

My goal is have one rake task called "deploy_demo" which purges the
database, migrates to the current schema, and loads the db from a set
of fixture files in a specified location.
I''ve written two new tasks the perform
