DBIx::Class::Migration::Script::Help::prepare - Create migration files.
dbic-migration prepare \ --lib=lib \ --schema_class=MyApp::Schema
migrations directory under "target_dir" (if they don't already exist) and makes deployment files for the current schema. If deployment files exist, will fail unless you "overwrite_migrations".
migrations directory reflects a directory structure as documented in DBIx::Class::DeploymentHandler.
If this is the first version, we create directories and initial DLL, etc. For versions greater than 1, we will also generate diffs and copy any fixture configs etc (as well as generating a fresh 'all_table.json' fixture config). For safety reasons, we never overwrite any fixture configs (even if
overwrite_migrations is true.)
This command accepts the following options. You may learn more about each option by typing
dbic-migration help OPTION. The following is a summary.
Accepts String, Optional.
Adds the listed paths to @INC. Handy during development when you want to use a development schema class.
Accepts Str. Required.
This is the schema we use as the basis for creating, managing and running your deployments. This should be the full package namespace defining your subclass of DBIx::Class::Schema. For example
If the "schema_class" cannot be loaded, a hard exception will be thrown.
Usually if you've already prepared migration files for the current version as specified in your "schema_class" we don't write out files even if you call
prepare. If you want to force overwrite previously prepared files (and lose all your customizations) you can do so with this option.
This option won't overwrite previously existing fixture configuration files.
Optional. String (Path to directory).
When using a
sandbox_class for generating developer level database sandboxes, you may wish to place the sandbox in a directory other than the default (which is under the
share directory off the project root).
Value: Str or Array of Str (default: SQLite). Optional.
By default we create migrations for SQLite. You can use this option to change that default, or to write our migrations for more than one database
You can prepare deployment for any database type that SQLT understands.
dbic-migration prepare --database SQLite --database MySQL --PostgreSQL
Please note if you choose to manually set this value, you won't automatically get the default or inferred type.
Aliases: T, sb
Accepts: String (default: SqliteSandbox)
The class we use to create a developer level database sandbox.
Connection information to an already created and running instance of a database. If you don't specify this, we will assume you want a developer level sandbox ( See "sandbox").
