I *think* this is the correct syntax: The::Schema::Customer->belongs_to( "account", "The::Schema::Account", { "foreign.id" => "self.account_id" }, { join_type => 'left' }, ); # The::Schema::Customer::account(): Unable to resolve relationship # from Customer to account: column account.left not loaded from # storage (or not passed to new() prior to insert()). Maybe you # forgot to call ->discard_changes to get defaults from the db. at # loader.pl line 38 So I tried this: The::Schema::Customer->belongs_to( "account", "The::Schema::Account", { join_type => 'left' }, { "foreign.id" => "self.account_id" } ); # The::Schema::Customer::account(): Unable to resolve relationship # from Customer to account: column account.left not loaded from # storage (or not passed to new() prior to insert()). Maybe you # forgot to call ->discard_changes to get defaults from the db. at # loader.pl line 38 And flailing: The::Schema::Customer->belongs_to( "account", "The::Schema::Account", { join_type => 'left', "foreign.id" => "self.account_id" }, ); # The::Schema::Customer::account(): Invalid rel cond key join_type # at loader.pl line 38 I can't tell from the docs which I want, but this (from DBIx::Class::Relationship) suggest that my first try might have been correct: # in a Book class (where Author has_many Books) __PACKAGE__->belongs_to( author => 'My::DBIC::Schema::Author', 'author', { join_type => 'left' } ); Also, you stated that "might_have is the LEFT JOIN version of has_many." The docs say "one-to-one". Which is correct? Should I change my code from might_have to belongs_to?
