-Static schemas (ones dumped to disk) will, by default, use the new-style 0.05XXX
+Static schemas (ones dumped to disk) will, by default, use the new-style
relationship names and singularized Results, unless you're overwriting an
-existing dump made by a 0.04XXX version of L<DBIx::Class::Schema::Loader>, in
-which case the backward compatible RelBuilder will be activated, and
-singularization will be turned off.
+existing dump made by an older version of L<DBIx::Class::Schema::Loader>, in
+which case the backward compatible RelBuilder will be activated, and the
+appropriate monikerization used.
Specifying
- naming => 'v5'
+ naming => 'current'
will disable the backward-compatible RelBuilder and use
the new-style relationship names along with singularized Results, even when
The option also takes a hashref:
- naming => { relationships => 'v5', monikers => 'v4' }
+ naming => { relationships => 'v6', monikers => 'v6' }
The keys are:
=item current
-Latest default style, whatever that happens to be.
+Latest style, whatever that happens to be.
+
+=item v4
+
+Unsingularlized monikers, C<has_many> only relationships with no _id stripping.
=item v5
-Version 0.05XXX style.
+Monikers singularized as whole words, C<might_have> relationships for FKs on
+C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships.
-=item v4
+Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for
+the v5 RelBuilder.
+
+=item v6
+
+All monikers and relationships are inflected using
+L<Lingua::EN::Inflect::Phrase>, and there is more aggressive C<_id> stripping
+from relationship names.
+
+In general, there is very little difference between v5 and v6 schemas.
+
+=item v7
+
+This mode is identical to C<v6> mode, except that monikerization of CamelCase
+table names is also done correctly.
-Version 0.04XXX style.
+CamelCase column names in case-sensitive mode will also be handled correctly
+for relationship name inflection.
+
+Currently, only Sybase ASE, MSSQL with CS/BIN collation and Firebird without
+the L<unquoted_ddl|DBIx::Class::Schema::Loader::DBI::InterBase/unquoted_ddl>
+option are in case-sensitive mode.
+
+If you don't have any CamelCase table or column names, you can upgrade without
+breaking any of your code.
=back
will set the C<cascade_delete> option to 0 for all generated relationships,
except for C<has_many>, which will have cascade_delete as 1.
-NOTE: this option is not supported if v4 backward-compatible naming is
-set either globally (naming => 'v4') or just for relationships.
-
=head2 debug
If set to true, each constructive L<DBIx::Class> statement the loader
returns a false value, the code falls back to default behavior
for that table name.
-The default behavior is to singularize the table name, and: C<join '', map
-ucfirst, split /[\W_]+/, lc $table>, which is to say: lowercase everything,
-split up the table name into chunks anywhere a non-alpha-numeric character
-occurs, change the case of first letter of each chunk to upper case, and put
-the chunks back together. Examples:
+The default behavior is to split on case transition and non-alphanumeric
+boundaries, singularize the resulting phrase, then join the titlecased words
+together. Examples:
- Table Name | Moniker Name
- ---------------------------
- luser | Luser
- luser_group | LuserGroup
- luser-opts | LuserOpt
+ Table Name | Moniker Name
+ ---------------------------------
+ luser | Luser
+ luser_group | LuserGroup
+ luser-opts | LuserOpt
+ stations_visited | StationVisited
+ routeChange | RouteChange
=head2 inflect_plural
File in Perl format, which should return a HASH reference, from which to read
loader options.
+=head1 preserve_case
+
+Usually column names are lowercased, to make them easier to work with in
+L<DBIx::Class>. This option lets you turn this behavior off, if the driver
+supports it.
+
+Drivers for case sensitive databases like Sybase ASE or MSSQL with a
+case-sensitive collation will turn this option on unconditionally.
+
+Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support
+setting this option.
