I have a model named Fact. A fact belongs to many other models and holds
some attributes. Think of it as a data-warehouse fact table.
class Fact
include DataMapper::Resource
belongs_to :patientposition, :key => true
belongs_to :controlpointcount, :key => true
belongs_to :radiationtype, :key => true
belongs_to :collimatormovement, :key => true
belongs_to :beamcount, :key => true
belongs_to :marctype, :key => true
property :valid, Boolean, :required => true, :default => true
property :marctestdate_count, Integer, :required => true, :default => 0
property :realvortest1_count, Integer, :required => true, :default => 0
timestamps :at
end
All of the other models are described in the same way:
class *Name*
include DataMapper::Resource
property :id, Serial
property :value, String, :required => true
validates_uniqueness_of :value
end
If I want to first_or_create a fact issuing e.g.
Fact.first_or_create("patientposition_id"=>2, "controlpointcount_id"=>3,
"radiationtype_id"=>1, "collimatormovement_id"=>1, "beamcount_id"=>4,
"marctype_id"=>3)
I get this error (which renders me helpless):
*wrong number of arguments (1 for 0)*

`create'
/Users/jo/.rvm/gems/[email protected]/gems/dm-core-1.2.0/lib/dm-core/model.rb:444:in
`first_or_create'
This error appears whether I use the ids or the actual model instance
queried from the database.
Any hints or ideas?
