Bizarre error: Can't fetch data as class method

[Dan Horne]

Hi all

This morning I generated my schema using DBIX::Schema::Loader and  
spent the best part of a day trying to debug the following message;

DBIx::Class::Row::get_column(): Can't fetch data as class method at  
(eval 74) line 6

After much faffing around, I managed to zero in on the error. i had  
the following definition in a class:

   "source_name",
   {
     data_type => "VARCHAR2",
     default_value => undef,
     is_nullable => 0,
     size => 50,
   },

It seems there must be some collision between the column name and  
something in DBIC. So, how can I progress if I can't change the column  
name in the underlying table?

Have you got a sample piece of your calling code that was giving the error?

You diagnosed everything correctly, this is an unfortunate clash. Look at
the POD for DBIC::ResultSource::add_columns(), especially the 'accessor'
attribute.

Cheers
