NAME
DBIx::Class::Manual::Troubleshooting - Got a problem? Shoot it."Can't locate storage blabla"
``Can't locate storage blabla''
You're trying to make a query on a non-connected schema. Make sure you got the current resultset from $schema->resultset('Artist') on a schema object you got back from connect().
Tracing SQL
The "DBIC_TRACE" environment variable controls SQL tracing, so to see what is happening try
export DBIC_TRACE=1
Alternatively use the "storage->debug" class method:-
$class->storage->debug(1);
To send the output somewhere else set debugfh:-
$class->storage->debugfh(IO::File->new('/tmp/trace.out', 'w');
Alternatively you can do this with the environment variable too:-
export DBIC_TRACE="1=/tmp/trace.out"
Can't locate method result_source_instance
For some reason the table class in question didn't load fully, so the ResultSource object for it hasn't been created. Debug this class in isolation, then try loading the full schema again.
Can't get last insert ID under Postgres with serial primary keys
Older DBI and DBD::Pg versions do not handle "last_insert_id" correctly, causing code that uses auto-incrementing primary key columns to fail with a message such as:
Can't get last insert id at /.../DBIx/Class/Row.pm line 95
In particular the RHEL 4 and FC3 Linux distributions both ship with combinations of DBI and DBD::Pg modules that do not work correctly.
DBI version 1.50 and DBD::Pg 1.43 are known to work.
... Can't locate object method "source_name" via package ...
... Can't locate object method ``source_name'' via package ...
There's likely a syntax error in the table class referred to elsewhere in this error message. In particular make sure that the package declaration is correct, so for a schema " MySchema " you need to specify a fully qualified namespace: " package MySchema::MyTable; " for example.
