Note that you should have a good +reason to create this under a new global namespace, otherwise use an +existing top level namespace for your schema class. + +C instructs this Helper to generate the named Schema +class for you, basing it on L (which +means the table information will always be dynamically loaded at +runtime from the database). + +C instructs this Helper to generate the named Schema +class for you, using L in "one shot" +mode to create a standard, manually-defined L +setup, based on what the Loader sees in your database at this moment. +A Schema/Model pair generated this way will not require +L at runtime, and will not automatically +adapt itself to changes in your database structure. You can edit +the generated classes by hand to refine them. + +C is the list of traits to apply to the model, see +L for details. + +C are described in L below. + +C arguments are the same as what +DBIx::Class::Schema::connect expects, and are storage_type-specific. +For DBI-based storage, these arguments are the dsn, username, +password, and connect options, respectively.
