STI doesn't work with more properties

Reported by Sherrod | May 31st, 2008 @ 02:59 AM

I don't know if this is a bug, a feature, or just plain unimplemented, but I am doing STI like so:

class Metaphor
  include DataMapper::Resource

  property :id,   Integer, :key => true
  property :x, Integer
  ...
  property :type, Discriminator
end

class Product < Metaphor
  property :name, String, :length => 255, :nullable => false
end

Then, while in the merb console, I do:

Product.create(:x => 200, :name => 'A Product')

and I get the error:

Sqlite3Error: table metaphors has no column named name

Is this not possible? I was under the impression STI was inheritance as in...inheritance?

    I've resolved this in my forked repo.

    git pull git://github.com/cilquirm/dm-core.git

    There's a new spec ( thanks to bernerdschafer ) that tests sti against your adapter ( or sqlite3 ) if you have it.

    I've tested it against sqlite3 and mysql.

    • State changed from “new” to “resolved”

    This should be fixed, now, as of commit 9e755c7bdae06f7fec433dff31bfe931a9b22874.

    We should be pushing this to a new gem soon.
