[Catalyst] Jason Kohles' tutorial on ExtJs editable data gridsandCatalyst

[jagdish eashwar]

Hi Ian,
Thanks a ton. It's really a lot clearer now. The name for the belongs_to
relationship was given by the AdventAjaxGrid2_create.pl when I created the
model. Disregarding the instruction not to modify anything above the md5sum
line, I changed the relationship name in People.pm from 'affiliation_id' to
'affiliation'.  I could then access the affiliation_id column in the People
table without having to mention the relationship name. Nice. But what is the
recommended way for getting around the problem of the catalyst helper using
the column name for the relationship name ? To what extent can one safely
disregard the 'don't modify' instruction?
