The application that I am working on uses myapp_create.pl to create the
model from the database schema.
The problem is that the DBIx::Schema::Loader is creating a relationship with
a name that is inappropriate, and conflicts with a relationship that I've
manually created.
tl;dr
Perhaps DBIx::Schema::Loader::Base will help.
moniker_map
Overrides the default table name to moniker translation. ...
The default behavior is to split on case transition and non-alphanumeric
boundaries, ..
Table Name | Moniker Name
-
luser| Luser
Using dbicdump, perhaps:
dbicdump -o dump_directory=./loader -o
moniker_map='{round=Round,rounds=Rounds}' Tennis::Schema
dbi:Pg:dbname=tennis002 '' ''
In this case, there is a table of group, employee and a third table
employee_group that links employees to groups. The group table has a
leader field that references an employee who is the group leader. DBIC has
decided to create a relationship on players called groups that basically
says what groups the employee is the leader of. Not a very good name, and
of course conflicts with the groups relationship that I created, that
indicates what groups an employee is actually in. (Yes, there is an
employee_groups relation, but I added the groups relation to bridge that
indirection.)
Looking at the documentation for DBIx::Schema::Loader, there is an option
called rel_collision_map that can supposedly be used to fix this. I'm unsure
how it works, and even less sure how to pass a hash as an option to the
myapp_create.pl script.
If that option is supported, examples would be helpful.
