=head1 NAME
=head1 CONSTRUCTOR OPTIONS
These constructor options are the base options for
-L<DBIx::Class::Schema::Loader/loader_opts>. Available constructor options are:
+L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
=head2 skip_relationships
Skip setting up relationships. The default is to attempt the loading
of relationships.
+=head2 skip_load_external
+
+Skip loading of other classes in @INC. The default is to merge all other classes
+with the same name found in @INC into the schema file we are creating.
+
+=head2 naming
+
+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 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 => 'current'
+
+will disable the backward-compatible RelBuilder and use
+the new-style relationship names along with singularized Results, even when
+overwriting a dump made with an earlier version.
+
+The option also takes a hashref:
+
+ naming => { relationships => 'v6', monikers => 'v6' }
+
+The keys are:
+
+=over 4
+
+=item relationships
+
+How to name relationship accessors.
+
+=item monikers
+
+How to name Result classes.
+
+=item column_accessors
+
+How to name column accessors in Result classes.
+
+=back
+
+The values can be:
+
+=over 4
+
+=item current
+
+Latest style, whatever that happens to be.
+
+=item v4
+
+Unsingularlized monikers, C<has_many> only relationships with no _id stripping.
+
+=item v5
+
+Monikers singularized as whole words, C<might_have> relationships for FKs on
+C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships.
+
+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.
+
+CamelCase column names in case-preserving mode will also be handled correctly
+for relationship name inflection. See L</preserve_case>.
+
+In this mode, CamelCase L</column_accessors> are normalized based on case
+transition instead of just being lowercased, so C<FooId> becomes C<foo_id>.
+
+If you don't have any CamelCase table or column names, you can upgrade without
+breaking any of your code.
+
+=back
+
+Dynamic schemas will always default to the 0.04XXX relationship names and won't
+singularize Results for backward compatibility, to activate the new RelBuilder
+and singularization put this in your C<Schema.pm> file:
+
+ __PACKAGE__->naming('current');
+
+Or if you prefer to use 0.05XXX features but insure that nothing breaks in the
+next major version upgrade:
+
+ __PACKAGE__->naming('v5');
+
+=head2 generate_pod
+
+By default POD will be generated for columns and relationships, using database
+metadata for the text if available and supported.
+
+Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only
+supported for Postgres right now.
+
+Set this to C<0> to turn off all POD generation.
+
+=head2 pod_comment_mode
+
+Controls where table comments appear in the generated POD. Smaller table
+comments are appended to the C<NAME> section of the documentation, and larger
+ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION>
+section to be generated with the comment always, only use C<NAME>, or choose
+the length threshold at which the comment is forced into the description.
+
+=over 4
+
+=item name
+
+Use C<NAME> section only.
+
+=item description
+
+Force C<DESCRIPTION> always.
+
+=item auto
+
+Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the
+default.
+
+=back
+
+=head2 pod_comment_spillover_length
+
+When pod_comment_mode is set to C<auto>, this is the length of the comment at
+which it will be forced into a separate description section.
+
+The default is C<60>
+
+=head2 relationship_attrs
+
+Hashref of attributes to pass to each generated relationship, listed
+by type. Also supports relationship type 'all', containing options to
+pass to all generated relationships. Attributes set for more specific
+relationship types override those set in 'all'.
+
+For example:
+
+ relationship_attrs => {
+ belongs_to => { is_deferrable => 1 },
+ },
+
+use this to make your foreign key constraints DEFERRABLE.
+
=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: 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 | LuserOpts
+ Table Name | Moniker Name
+ ---------------------------------
+ luser | Luser
+ luser_group | LuserGroup
+ luser-opts | LuserOpt
+ stations_visited | StationVisited
+ routeChange | RouteChange
=head2 inflect_plural
=head2 result_base_class
-Base class for your table classes (aka result classes). Defaults to 'DBIx::Class'.
+Base class for your table classes (aka result classes). Defaults to
+'DBIx::Class::Core'.
=head2 additional_base_classes
=head2 components
List of additional components to be loaded into all of your table
-classes. A good example would be C<ResultSetManager>.
+classes. A good example would be
+L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime>
=head2 resultset_components
=head2 use_namespaces
+This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass
+a C<0>.
+
Generate result class names suitable for
L<DBIx::Class::Schema/load_namespaces> and call that instead of
L<DBIx::Class::Schema/load_classes>. When using this option you can also
of the rest of your code for that matter). Don't blame me if a bug in this
code wipes something out when it shouldn't have, you've been warned.
+=head2 overwrite_modifications
+
+Default false. If false, when updating existing files, Loader will
+refuse to modify any Loader-generated code that has been modified
+since its last run (as determined by the checksum Loader put in its
+comment lines).
+
+If true, Loader will discard any manual modifications that have been
+made to Loader-generated code.
+
+Again, you should be using version control on your schema classes. Be
+careful with this option.
+
+=head2 custom_column_info
+
+Hook for adding extra attributes to the
+L<column_info|DBIx::Class::ResultSource/column_info> for a column.
+
+Must be a coderef that returns a hashref with the extra attributes.
+
+Receives the table name, column name and column_info.
+
+For example:
+
+ custom_column_info => sub {
+ my ($table_name, $column_name, $column_info) = @_;
+
+ if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
+ return { is_snoopy => 1 };
+ }
+ },
+
+This attribute can also be used to set C<inflate_datetime> on a non-datetime
+column so it also receives the L</datetime_timezone> and/or L</datetime_locale>.
+
+=head2 datetime_timezone
+
+Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all
+columns with the DATE/DATETIME/TIMESTAMP data_types.
+
+=head2 datetime_locale
+
+Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all
+columns with the DATE/DATETIME/TIMESTAMP data_types.
+
+=head1 config_file
+
+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.
+
=head1 METHODS
None of these methods are intended for direct invocation by regular
-users of L<DBIx::Class::Schema::Loader>. Anything you can find here
-can also be found via standard L<DBIx::Class::Schema> methods somehow.
+users of L<DBIx::Class::Schema::Loader>. Some are proxied via
+L<DBIx::Class::Schema::Loader>.
