belongs_to does not create the foreign-key property for Namespaced models
Reported by Postmodern | April 27th, 2008 @ 02:33 AM
The belongs_to association does not create the foreign-key property for models within a Namespace.
module Namespace
class Bird < DataMapper::Base
property :lol, :string
has_many :feathers
end
class Feather < DataMapper::Base
property :lol, :string
belongs_to :bird
end
end
Namespace::Bird.auto_migrate!
Namespace::Feather.auto_migrate!
$ sqlite3 test.db
sqlite> .schema
CREATE TABLE "namespace/birds" ("id" INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, "lol" TEXT);
CREATE TABLE "namespace/feathers" ("id" INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, "lol" TEXT);

Temporary work-around for DataMapper 0.3.1, manually add the foreign-key property to the model:
property :bla_id, :integer belongs_to :bla -

Although the above work-around creates the needed columns, it does not fix the associations.
include Namespace bird = Bird.create(:lol => 'haha') bird.feathers << Feather.new(:lol => 'haha')Produces:

I am also having this issue.
A poor workaround is to remove the belongs_to and create methods manually.

We'll give it a stab. Adam, please see what you can do about this. We'll fix up the DM 0.3.x associations real quick for that other work project for now so it'll be win/win for everyone...

Is this still an issue? I notice the ticket is a month old with no follow up....

Unless there's been a new 0.3.x release that fixes it, yes it's still an issue.

That's not the point. Some of us can't easily move to 0.9.x yet.

Resolved in 0.9.x. Happy to apply a patch for 0.3.x if anyone contributes one.
