Hi, I'm having problems working out how to specify the name of the join table in a (non-) anonymous many-to-many relationship in an unchangeable legacy database.
In SQL terms, I have three tables foo, bar and foo_bar (foo_bar being the join table, and that only having foo_id and bar_id columns). All table names are singular. I have made several attempts to model the relationship, the closest I can get it is with this: class Foo include DataMapper::Resource storage_names[:default] = 'foo' property :id, Serial property :a_column, String has n, :bars, :through => Resource end class Bar include DataMapper::Resource storage_names[:default] = 'bar' property :id, Serial property :a_column, String has n, :foos, :through => Resource end Except the join table's name comes out as "bar_foos". Close! I tried using "has n, :foos, :through => :foo_bars" and having the foo_bars class as: class FooBar include DataMapper::Resource storage_names[:default] = 'foo_bar' belongs_to :foo belongs_to :bar end But I'm told there's no key defined. Adding ":key => true" to both of them doesn't work. I looked through dm-core/associations/many_to_many.rb but there doesn't seem to be a way to name it through options, and my Ruby isn't good enough to discern how it does its magic! ;o) Is it possible? How can I set the join table's name? Cheers, -Carl -- You received this message because you are subscribed to the Google Groups "DataMapper" group.
