+=head2 col_accessor_map
+
+Same as moniker_map, but for column accessor names. If a coderef is
+passed, the code is called with arguments of
+
+ the name of the column in the underlying database,
+ default accessor name that DBICSL would ordinarily give this column,
+ {
+ table_class => name of the DBIC class we are building,
+ table_moniker => calculated moniker for this table (after moniker_map if present),
+ table_name => name of the database table,
+ full_table_name => schema-qualified name of the database table (RDBMS specific),
+ schema_class => name of the schema class we are building,
+ column_info => hashref of column info (data_type, is_nullable, etc),
+ }
+
=head2 inflect_plural
Just like L</moniker_map> above (can be hash/code-ref, falls back to default
Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all
columns with the DATE/DATETIME/TIMESTAMP data_types.
+=head2 datetime_undef_if_invalid
+
+Pass a C<0> for this option when using MySQL if you B<DON'T> want C<<
+datetime_undef_if_invalid => 1 >> in your column info for DATE, DATETIME and
+TIMESTAMP columns.
+
+The default is recommended to deal with data such as C<00/00/00> which
+sometimes ends up in such columns in MySQL.
+
=head2 config_file
File in Perl format, which should return a HASH reference, from which to read
col_collision_map => { '(foo).*(bar)' => 'column_%s_%s' }
+=head2 rel_collision_map
+
+Works just like L</col_collision_map>, but for relationship names/accessors
+rather than column names/accessors.
+
+The default is to just append C<_rel> to the relationship name, see
+L</RELATIONSHIP NAME COLLISIONS>.

Another option is to use the L</col_collision_map> option.
+=head1 RELATIONSHIP NAME COLLISIONS
+
+In very rare cases, you may get a collision between a generated relationship
+name and a method in your Result class, for example if you have a foreign key
+called C<belongs_to>.
+
+This is a problem because relationship names are also relationship accessor
+methods in L<DBIx::Class>.
+
+The default behavior is to append C<_rel> to the relationship name and print
+out a warning that refers to this text.
+
+You can also control the renaming with the L</rel_collision_map> option.
