=head2  "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().

=head2 Tracing SQL

The C<DBIC_TRACE> environment variable controls
SQL tracing, so to see what is happening try

  export DBIC_TRACE=1

Alternatively use the C<< 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"

=head2 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.

=head2 Can't get last insert ID under Postgres with serial primary keys

Older L<DBI> and L<DBD::Pg> versions do not handle C<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 L<DBI> and L<DBD::Pg> modules that do not work
correctly.

L<DBI> version 1.50 and L<DBD::Pg> 1.43 are known to work.

=head2 ... 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 C< MySchema > you need to
specify a fully qualified namespace: C< package MySchema::MyTable; >
for example.
