So please ignore any prior remarks regarding the cause of the problem and here is the observed behavior using the classic Product and Price classes as examples:
Here are two classes, the first works as expected the second fails with the listed error message:
Working class:
package Product;
use My::DB ;
use base qw(My::DB::Object);
__PACKAGE__->meta->setup
( table => 'product'
, columns =>
[ 'Id' => { type => 'integer', primary_key => 1, sequence =>
'Product_Id_Seq' }
#
# Name Null? Type
# ----------------------------------------- --------
-------------------
# 'Id' # Not Null Number(38)
, 'Name' # Not Null
varchar2(255)
]
, unique_key => 'Name'
, relationships =>
[ Prices =>
{ class => 'Product::Price'
, key_columns => { Id => 'Product_Id' }
, type => 'one to many'
},
]
) ;
Class which does not work:
package Product;
use My::DB ;
use base qw(My::DB::Object);
__PACKAGE__->meta->setup
( table => 'product'
, columns =>
[ 'Id' => { type => 'integer', primary_key => 1, sequence =>
'Product_Id_Seq' }
#
# Name Null? Type
# ----------------------------------------- --------
-------------------
# 'Id' # Not Null Number(38)
, 'Name' # Not Null
varchar2(255)
]
, unique_key => 'Name'
, relationships =>
[ Price =>
{ class => 'Product::Price'
, key_columns => { Id => 'Product_Id' }
, type => 'one to many'
},
]
) ;
Use of which results in the following error message:
Can't call method "Id" on unblessed reference at
.../Rose/DB/Object/MakeMethods/Generic.pm line 3470.
The single change is that the name of the relationship is 'Prices' in the working version and 'Price'
in the broken version. In both cases, the detail class is 'Product::Price'.I've attached complete versions of the regional pricing both working and not working including test logs:
regional-pricing/working/log/1.use.txt regional-pricing/working/log/2.new.txt regional-pricing/working/log/3.fields.txt regional-pricing/working/log/4.save.txt regional-pricing/working/log/5.load.txt regional-pricing/bug/log/1.use.txt regional-pricing/bug/log/2.new.txt regional-pricing/bug/log/3.fields.txtWith regional-pricing/bug/log/3.fields.txt containing the listed error message.
