DBIx::Class::Manual::Troubleshooting - Got a problem? Shoot it.
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().
The DBIC_TRACE environment variable controls SQL tracing, so to see what is happening try
DBIC_TRACE
export DBIC_TRACE=1
Alternatively use the storage->debug class method:-
storage->debug
$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"
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.
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:
last_insert_id
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.
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.
MySchema
package MySchema::MyTable;
To install DBIx::Class, copy and paste the appropriate command in to your terminal.
