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.
