SYNOPSIS

# in startup
$app->plugin('Data::Transfigure' => {
  renderers => [qw(json openapi)]
});

$app->transfig->output->add_transfigurators(
  Data::Transfigure::Type->new(
    type => "App::Model::Result::Book",
    handler => sub($data) {
      +{
        id     => $data->id,
        name   => $data->name,
        author => $data->author,
      }
    }
  ),
  Data::Transfigure::Type->new(
    type => 'App::Model::Result::Person',
    handler => sub($data) {
      +{
        id        => $data->id,
        firstname => $data->names->[0],
        lastname  => $data->names->[1],
      }
    }
  )
);

$app->transfig->input->add_transfigurators(
  Data::Transfigure::Position->new(
    position => '/**/author',
    handler  => sub($data) {
      +{
        id    => $data->id,
        names => [$data->{firstname}, $data->{lastname}]
      }
    } 
  )

# in controller
sub get_book($self) {
  my $book = $self->model("Book")->find($self->param('id'));
  $self->render(json => $book);
}

sub update_book($self) {
  my $book = $self->model("Book")->find($self->param('id'));
  my $data = $self->transfig->json;

  $book->author->update(delete($data->{author}));
  $book->update($data);
  $book->discard_changes;
  $self->render(json => $book);
}

DESCRIPTION

This plugin is an adapter to make Data::Transfigure a bit more convenient to use in Mojolicious applications. Two transfigurators are created for you: one for data input, and the other for output. The default output transfigurator is automatically invoked when rendering data via any of the methods configured as "renderers". The default input transfigurator is manually invoked by calling the transfig.json helper rather than, e.g., $c->req->json.

METHODS

Mojolicious::Plugin::Data::Transfigure inherits all methods from Mojolicious::Plugin and implements the following new ones

register

Register the plugin in a Mojolicious application. Configuration via named arguments:

bare

Configures the default input and output transfigurators to be initialized with no transfigurations instead of their usual default sets.

prefix

Configures the prefix used for the module's Mojolicious helper functions. This documentation assumes that it is left unchanged

Default: transfig

renderers

Controls which output rendering functions (e.g., text, json) are intercepted and automatically transfigured before being delivered to the client

Default: ['json']

HELPERS

transfig.input

app->transfig->input

Returns the default input transfigurator. Add transfigurations to it by calling add_transfigurator()/add_transfigurator_at() on the return value.

By default, the following transfigurators are configured, unless the "bare" configuration option is enabled:

transfig.output

app->transfig->output

Returns the default output transfigurator. Add transfigurations to it by calling add_transfigurator()/add_transfigurator_at() on the return value.

By default, the following transfigurators are configured, unless the "bare" configuration option is enabled:

transfig.json

app->transfig->json
app->transfig->json(transfigurator => $t)

Returns the request body, decoded as JSON, and passed through the input transfigurator. "transfig.input" is used by default, but an alternative transfigurator may be passed in via the transfigurator argument.
