Hello guys
I'm trying to work with a lot of through associations, but they seem to fail.
Here's an example incl. test:
Anyone got an idea how to fix this?
require 'rubygems'
require 'bacon'
require 'dm-core'
File.unlink('model.log') rescue
DataMapper::Logger.new('model.log', :debug)
DataMapper.setup(:default, 'sqlite3::memory:')
dir = File.dirname(__FILE__)
class League
include DataMapper::Resource
property :id, Serial
property :name, String
has n, :league_membership
has n, :player, :through => :league_membership
end
class LeagueMembership
include DataMapper::Resource
property :id, Serial
belongs_to :player
belongs_to :league
has n, :league_event
end
class Player
include DataMapper::Resource
property :id, Serial
property :name, String
has n, :league_membership
has n, :league, :through => :league_membership
end
class LeagueEvent
include DataMapper::Resource
property :id, Serial
property :reason, Text
belongs_to :league_membership
belongs_to :player, :through => :league_membership
belongs_to :league, :through => :league_membership
end
DataMapper.auto_migrate!
describe 'League' do
before do
@league = League.create :name => "foo"
@player = Player.create :name => "bar"
@mem = LeagueMembership.create(:player => @player, :league => @league)
@event = LeagueEvent.create(:reason => "win", :league_membership => @mem)
@event.reload
end
it 'should query with through assoc' do
@mem.league.should.equal @league
@mem.player.should.equal @player
@event.player.should.equal @player
@event.league.should.equal @league
end
end
