How do you imagine yourself a request with join beetween 2 tables in
different databases?
This is the reason you can't make relationships between different schemas.
If it's not a typo, the two schemas connect to the same database on the
mysql side...
Anyway, I think DBIC sees them as two different databases, even if their
connections strings are the same...

<mailto:[EMAIL PROTECTED]>>:
I am working on two Catalyst applications and had earlier set up
separate Mysql databases for each of them. Since some of the tables
that these two applications use, are the same, I put the common
tables in a third database and created two models in each of the
Catalyst applications. I am, however, unable to set up
relationships between tables in the common and specific databases.
I used myapp_create.pl to create the two models:
perl script/hardware_create.pl model MyhardwareDB DBIC::Schema
Myhardware::Schema::MyhardwareDB create=static dbi:mysql:hardware
'jag' 'passwd' '{ AutoCommit => 1 }'
perl script/hardware_create.pl model CommonDB DBIC::Schema
Myhardware::Schema::CommonDB create=static dbi:mysql:hardware 'jag'
'passwd' '{ AutoCommit => 1 }'
and then put in the relationships between the employee and hardware
tables as under:
# in Emp.pm
#employee has many hardware
__PACKAGE__->has_many(emp_hm_hw =>
'Myhardware::Schema::MyhardwareDB::Hardware', 'hw_emp_id');
# in Hardware.pm
#hardware belongs to employee
__PACKAGE__->belongs_to(hw_bt_emp_id =>
'Myhardware::Schema::CommonDB::Emp','hw_emp_id');
When I use these accessors in the tt2 templates, i get an undef error.
undef error - DBIx::Class::Relationship::Accessor::__ANON__(): Can't
find source for Myhardware::Schema::MyhardwareDB::Hardware at
/home/jag/catalyst_trials/Myhardware/root/src/usr_fragment.tt2 line 8
What am I doing wrong?
