NAME
DBIx::Class::Schema::PopulateMore::Command - Command Class to Populate a SchemaDESCRIPTION
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 populatingexception_cb
contains a callback to the exception method supplied by DBICdefinitions
This is an arrayref of information used to populate tables in the databasematch_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 neaterrs_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 resultget_rs_index
given an index, returns the related inflated resultsetinflator_loader
Loads each of the available inflators, provider access to the objectsinflator_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" attributeexecute
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 inflatorcreate_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
