Hello again,
I tried to add a 'many to many' relationship between two of my
classes. I followed the tutorial and everything works as long as I
define foreign_keys for the mapping table:
__PACKAGE__->meta->foreign_keys(
therapeut =>
{
class => 'PVonline::Therapeuten',
key_columns => { therapeut_id => 'nr' },
},
gruppe =>
{
class => 'PVonline::Gruppen',
key_columns => { gruppe_id => 'nr' },
},
);
But then I tried to change this to normal relationships as stated in
the tutorial:
__PACKAGE__->meta->relationships(
therapeut => {
type => 'many to one',
class => 'PVonline::Therapeuten',
column_map => { therapeut_id => 'nr'},
},
gruppe => {
type => 'many to one',
class => 'PVonline::Gruppen',
column_map => { gruppe_id => 'nr'},
},
);
To my understanding the two definitions should be equivalent but with
the second I get the error message:
Don't know how to auto-join relationship 'gruppe' of type 'many to
one' at C:/Perl/site/lib/Rose/DB/Object/MakeMethods/Generic.pm line
3330
Any pointers, what I am doing wrong here?
Cheers,
Michael
