NAME

       DBIx::Class::Schema::PopulateMore::Command - Command Class to Populate a Schema

DESCRIPTION

       This is a command pattern  class to manage the job of populating a DBIx::Class::Schema
       with information.  We break this out because the actual job is a bit complex, is likely to
       grow more complex, and so that we can more easily identify refactorable and reusable
       parts.

ATTRIBUTES

       This class defines the following attributes.

   schema
       This is the Schema we are populating

   exception_cb
       contains a callback to the exception method supplied by DBIC

   definitions
       This is an arrayref of information used to populate tables in the database

   match_condition
       How we know the value is really something to inflate or perform a substitution on.  This
       get's the namespace of the substitution plugin and it's other data.

   visitor
       We define a visitor so that we can perform the value inflations and or substitutions.
       This is still a little work in progress, but it's getting neater

   rs_index
       The index of previously inflated resultsets.  Basically when we create a new row in the
       table, we cache the result object so that it can be used as a dependency in creating
       another.

       Eventually will be moved into the constructor for a plugin

   set_rs_index
       Set an index value to an inflated result

   get_rs_index
       given an index, returns the related inflated resultset

   inflator_loader
       Loads each of the available inflators, provider access to the objects

   inflator_dispatcher
       Holds an object that can perform dispatching to the inflators.

METHODS

       This module defines the following methods.

   _build_visitor
       lazy build for the "visitor" attribute.

   _build_inflator_loader
       lazy build for the "inflator_loader" attribute

   _build_inflator_dispatcher
       lazy build for the "inflator_dispatcher" attribute

   execute
       The command classes main method.  Returns a Hash of the created result rows, where each
       key is the named index and the value is the row object.

   dispatch_inflator
       Dispatch to the correct inflator

   create_fixture({})
       Given a hash suitable for a DBIx::Class::Resultset create method, attempt to update or
       create a row in the named source.

       returns the newly created row or throws an exception if there is a failure

   merge_fields_values
       Given a fields and values, combine to a hash suitable for using in a create_fixture row
       statement.

   field_value
       Correctly create an array from the fields, values variables, skipping those where the
       value is undefined.

   coerce_to_array
       given a value that is either an arrayref or a scalar, put it into array context and return
       that array.
