=head1 SYNOPSIS
-See L<DBIx::Class::Schema::Loader>
+See L<DBIx::Class::Schema::Loader>.
=head1 DESCRIPTION
The option also takes a hashref:
- naming => { relationships => 'v7', monikers => 'v7' }
+ naming => {
+ relationships => 'v8',
+ monikers => 'v8',
+ column_accessors => 'v8',
+ force_ascii => 1,
+ }
+
+or
+
+ naming => { ALL => 'v8', force_ascii => 1 }
The keys are:
=over 4
+=item ALL
+
+Set L</relationships>, L</monikers> and L</column_accessors> to the specified
+value.
+
=item relationships
How to name relationship accessors.
How to name column accessors in Result classes.
+=item force_ascii
+
+For L</v8> mode and later, uses L<String::ToIdentifier::EN> instead of
+L<String::ToIdentifier::EM::Unicode> to force monikers and other identifiers to
+ASCII.
+
=back
The values can be:
=item v7
This mode is identical to C<v6> mode, except that monikerization of CamelCase
-table names is also done correctly.
+table names is also done better (but best in v8.)
-CamelCase column names in case-preserving mode will also be handled correctly
-for relationship name inflection. See L</preserve_case>.
+CamelCase column names in case-preserving mode will also be handled better
+for relationship name inflection (but best in v8.) 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.
+=item v8
+
+(EXPERIMENTAL)
+
+The default mode is L</v7>, to get L</v8> mode, you have to specify it in
+L</naming> explicitly until C<0.08> comes out.
+
+L</monikers> and L</column_accessors> are created using
+L<String::ToIdentifier::EN::Unicode> or L<String::ToIdentifier::EN> if
+L</force_ascii> is set; this is only significant for names with non-C<\w>
+characters such as C<.>.
+
+CamelCase identifiers with words in all caps, e.g. C<VLANValidID> are supported
+correctly in this mode.
+
+For relationships, belongs_to accessors are made from column names by stripping
+postfixes other than C<_id> as well, for example just C<Id>, C<_?ref>, C<_?cd>,
+C<_?code> and C<_?num>, case insensitively.
=item preserve
By default POD will be generated for columns and relationships, using database
metadata for the text if available and supported.
-Metadata can be stored in two ways.
+Comment metadata can be stored in two ways.
The first is that you can create two tables named C<table_comments> and
-C<column_comments> respectively. They both need to have columns named
-C<table_name> and C<comment_text>. The second one needs to have a column
-named C<column_name>. Then data stored in these tables will be used as a
-source of metadata about tables and comments.
+C<column_comments> respectively. These tables must exist in the same database
+and schema as the tables they describe. They both need to have columns named
+C<table_name> and C<comment_text>. The second one needs to have a column named
+C<column_name>. Then data stored in these tables will be used as a source of
+metadata about tables and comments.
(If you wish you can change the name of these tables with the parameters
L</table_comments_table> and L</column_comments_table>.)
-As a fallback you can use built-in commenting mechanisms. Currently this
-is only supported for PostgreSQL and MySQL. To create comments in
-PostgreSQL you add statements of the form C<COMMENT ON TABLE some_table ...>.
-To create comments in MySQL you add C<COMMENT '...'> to the end of the
-column or table definition. Note that MySQL restricts the length of comments,
-and also does not handle complex Unicode characters properly.
+As a fallback you can use built-in commenting mechanisms. Currently this is
+only supported for PostgreSQL, Oracle and MySQL. To create comments in
+PostgreSQL you add statements of the form C<COMMENT ON TABLE some_table IS

+C<COMMENT '...'> to the end of the column or table definition. Note that MySQL
+restricts the length of comments, and also does not handle complex Unicode
+characters properly.
Set this to C<0> to turn off all POD generation.
The table to look for comments about tables in. By default C<table_comments>.
See L</generate_pod> for details.
+This must not be a fully qualified name, the table will be looked for in the
+same database and schema as the table whose comment is being retrieved.
+
=head2 column_comments_table
The table to look for comments about columns in. By default C<column_comments>.
See L</generate_pod> for details.
+This must not be a fully qualified name, the table will be looked for in the
+same database and schema as the table/column whose comment is being retrieved.
+
=head2 relationship_attrs
Hashref of attributes to pass to each generated relationship, listed
=head2 db_schema
Set the name of the schema to load (schema in the sense that your database
-vendor means it). Does not currently support loading more than one schema
-name.
+vendor means it).
+
+Can be set to an arrayref of schema names for multiple schemas, or the special
+value C<%> for all schemas.
+
+For MSSQL, Sybase ASE, and Informix can be set to a hashref of databases as
+keys and arrays of owners as values, set to the value:
+
+ { '%' => '%' }
+
+for all owners in all databases.
+
+Name clashes resulting from the same table name in different databases/schemas
+will be resolved automatically by prefixing the moniker with the database
+and/or schema.
+
+To prefix/suffix all monikers with the database and/or schema, see
+L</moniker_parts>.
+
+=head2 moniker_parts
+
+The database table names are represented by the
+L<DBIx::Class::Schema::Loader::Table> class in the loader, the
+L<DBIx::Class::Schema::Loader::Table::Sybase> class for Sybase ASE and
+L<DBIx::Class::Schema::Loader::Table::Informix> for Informix.
+
+Monikers are created normally based on just the
+L<name|DBIx::Class::Schema::Loader::DBObject/name> property, corresponding to
+the table name, but can consist of other parts of the fully qualified name of
+the table.
+
+The L</moniker_parts> option is an arrayref of methods on the table class
+corresponding to parts of the fully qualified table name, defaulting to
+C<['name']>, in the order those parts are used to create the moniker name.
+
+The C<'name'> entry B<must> be present.
+
+Below is a table of supported databases and possible L</moniker_parts>.

=head2 constraint
=head2 moniker_map
-Overrides the default table name to moniker translation. Can be either
-a hashref of table keys and moniker values, or a coderef for a translator
-function taking a single scalar table name argument and returning
-a scalar moniker. If the hash entry does not exist, or the function
-returns a false value, the code falls back to default behavior
-for that table name.
+Overrides the default table name to moniker translation. Can be either a

+(which stringifies to the unqualified table name) and returning a scalar
+moniker. If the hash entry does not exist, or the function returns a false
+value, the code falls back to default behavior for that table name.
The default behavior is to split on case transition and non-alphanumeric
boundaries, singularize the resulting phrase, then join the titlecased words
{
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,
+ table => table object of interface DBIx::Class::Schema::Loader::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),
- }
+ }
+
+the L<table object|DBIx::Class::Schema::Loader::Table> stringifies to the
+unqualified table name.
=head2 rel_name_map
Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
+=head2 schema_components
+
+List of components to load into the Schema class.
+
=head2 result_base_class
Base class for your table classes (aka result classes). Defaults to
List of additional classes which all of your table classes will use.
-=head2 schema_components
-
-List of components to load into the Schema class.
-
=head2 components
List of additional components to be loaded into all of your Result

],
}
-
+
You may use this in conjunction with L</components>.
=head2 result_roles
],
RouteChange => 'YourApp::Role::TripEvent',
}
-
+
You may use this in conjunction with L</result_roles>.
=head2 use_namespaces
Must be a coderef that returns a hashref with the extra attributes.
-Receives the table name, column name and column_info.
+Receives the L<table object|DBIx::Class::Schema::Loader::Table> (which
+stringifies to the unqualified table name), column name and column_info.
For example:
custom_column_info => sub {
- my ($table_name, $column_name, $column_info) = @_;
+ my ($table, $column_name, $column_info) = @_;
if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
return { is_snoopy => 1 };
=head2 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.
+Normally database names are lowercased and split by underscore, use this option
+if you have CamelCase database names.
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.
+B<NOTE:> L</naming> = C<v8> is highly recommended with this option as the
+semantics of this mode are much improved for CamelCase database names.
+
+L</naming> = C<v7> or greater is required with this option.
=head2 qualify_objects
Set to true to prepend the L</db_schema> to table names for C<<
__PACKAGE__->table >> calls, and to some other things like Oracle sequences.
+This attribute is automatically set to true for multi db_schema configurations.
+
=head2 use_moose
Creates Schema and Result classes that use L<Moose>, L<MooseX::NonMoose> and
-L<namespace::autoclean>. The default content after the md5 sum also makes the
-classes immutable.
+L<MooseX::MarkAsMethods> (or L<namespace::autoclean>, see below). The default
+content after the md5 sum also makes the classes immutable.
It is safe to upgrade your existing Schema to this option.
+=head2 only_autoclean
+
+By default, we use L<MooseX::MarkAsMethods> to remove imported functions from
+your generated classes. It uses L<namespace::autoclean> to do this, after
+telling your object's metaclass that any operator L<overload>s in your class
+are methods, which will cause namespace::autoclean to spare them from removal.
+
+This prevents the "Hey, where'd my overloads go?!" effect.
+
+If you don't care about operator overloads, enabling this option falls back to
+just using L<namespace::autoclean> itself.
+
+If none of the above made any sense, or you don't have some pressing need to
+only use L<namespace::autoclean>, leaving this set to the default is
+recommended.
+
=head2 col_collision_map
This option controls how accessors for column names which collide with perl
on tables to primary keys, assuming there is only one largest unique
constraint.
+=head2 filter_generated_code
+
+An optional hook that lets you filter the generated text for various classes
+through a function that change it in any way that you want. The function will
+receive the type of file, C<schema> or C<result>, class and code; and returns
+the new code to use instead. For instance you could add custom comments, or do
+anything else that you want.
+
+The option can also be set to a string, which is then used as a filter program,
+e.g. C<perltidy>.
+
+If this exists but fails to return text matching C</\bpackage\b/>, no file will
+be generated.
+
+ filter_generated_code => sub {
+ my ($type, $class, $text) = @_;
