Hey there.

I am starting on my first active warehouse project.  I understand the
current active warehouse plugin is not compabable with rails 2.1.  But I am
going to get (at least) the sample project in
active_warehouse/rails_warehouse to work.

I will detail my frustra.... progress.  once I have a working plugin with
2.1, what should I do then to release it ?

thanks much

Brad

Hi Brad,

Why don't you post back your results to the list.  I know we'll be
upgrading to 2.1 in the near future so we'll need to do the same
thing.  I'm sure between us we can get a pull request put together so
it will be done.

Cheers,
Marty

Hi Brad,
do you intend on creating a fork on GitHub for this ? (here
http://github.com/aeden/activewarehouse/tree/master and here
http://github.com/bcotton/activewarehouse-demo/tree/master)

I could be a convenient way to share your changes, while ensuring it will be
easy to push them back into the main branch.

Just a though - maybe that's what you already intented to do ?

cheers and keep us posted!

Get in touch with Darin Wilson, who posted a few weeks ago.  He said he was going to work on patching AW and/or the sample project for 2.1.

Hi all-

I think this is the post you're referring to:

http://rubyforge.org/pipermail/activewarehouse-discuss/2008-August/000307.ht
ml

I haven't actually been able to start getting aw-etl to work with Rails 2.1,
but the patch I supplied in this post lets you take advantage of the
vendor/rails feature, so you can use a frozen version of Rails with aw-etl.
This is useful if you're running on a machine that has 2.1 installed on the
system level and you want to bypass that (at least for now).

HTH,
Darin

Subject: [Activewarehouse-discuss] non sum views
Message-ID: <7140a9950809081242o665e6227s5a7c741d4e5e2737@mail.gmail.com>

I'm working on a proof of concept using the active warehouse plugin.

I have my dimension tables as

city_dimension (country_name, state_name, city_name)
person_dimension (first_name, last_name, city_id)
company_dimensoin (name, city_id)

my facts are the projects that tie them together

project_facts (:title, :city_id, :person_id, company_id)

here is a cube that sorta works....
class CityPeopleCube < ActiveWarehouse::Cube
  reports_on :project
  pivots_on :city, :person
end

and my fact file...

class ProjectFact < ActiveWarehouse::Fact

  aggregate :title

  dimension :date
  dimension :city
  dimension :person
  dimension :organization
end

of course, it tries to place a sum(project_facts.title) in the SQL query.  I
would rather not do that.   I looked at the
lib/active_warehouse/aggregate/aggregate.rb and ../aggregate_field.rb  but I
don't see a way to override the
strategy_name = :sum.  Well, I can do

aggregrate :title, :type => :string
but then my SQL query will crash when it wraps the project_facts.title with
string.

any ideas ?

my ProjectFact has an incorrect line

dimension :organization should be dimension :company.

As you're probably aware, strings rarely appear on facts, because they're not additive (can't be summed, averaged, etc.).  The one exception I'm aware of is degenerate dimensions.  

So, if "title" is a degenerate dimension in your schema, you shouldn't specify it as an aggregate.  That, is you should probably remove "aggregate :title" from the fact.  The problem with that is you would no longer have any aggregates.  You can fix this by adding:

aggregate :id, :type => :count

Which will do a count on the ids in the fact table - basically a "Number of Projects" aggregate.  In fact, the :type parameter is what you use to override strategy_name in general.  It can be any SQL aggregate function (avg, max, or whatever else your db supports.)  You can also add :distinct => true, if that's what you're looking for.
