  csrf_token
  my $token   = $validation->csrf_token;
  $validation = $validation->csrf_token('fa6a08...');

CSRF token.

  input
  my $input   = $validation->input;
  $validation = $validation->input({foo => 'bar', baz => [123, 'yada']});

Data to be validated.

  output
  my $output  = $validation->output;
  $validation = $validation->output({});

Validated data.

  topic
  my $topic   = $validation->topic;
  $validation = $validation->topic('foo');

Name of field currently being validated.

  validator
  my $validator = $validation->validator;
  $validation   = $validation->validator(Mojolicious::Validator->new);

Mojolicious::Validator object this validation belongs to.

METHODS
Mojolicious::Validator::Validation inherits all methods from Mojo::Base and implements the following new ones.

  check
  $validation = $validation->check('size', 2, 7);

Perform validation check on all values of the current "topic", no more checks will be performed on them after the first one failed.

  csrf_protect
  $validation = $validation->csrf_protect;

Validate "csrf_token" and protect from cross-site request forgery.

  error
  my $err     = $validation->error('foo');
  $validation = $validation->error(foo => ['custom_check']);

Get or set details for failed validation check, at any given time there can only be one per field.

  # Details about failed validation
  my ($check, $result, @args) = @{$validation->error('foo')};

  every_param
  my $values = $validation->every_param('foo');

Similar to "param", but returns all values sharing the same name as an array reference.

  # Get first value
  my $first = $validation->every_param('foo')->[0];

  failed
  my $names = $validation->failed;

Return a list of all names for values that failed validation.

  # Names of all values that failed
  say for @{$validation->failed};

  has_data
  my $bool = $validation->has_data;

Check if "input" is available for validation.

  has_error
  my $bool = $validation->has_error;
  my $bool = $validation->has_error('foo');

Check if validation resulted in errors, defaults to checking all fields.

  is_valid
  my $bool = $validation->is_valid;
  my $bool = $validation->is_valid('foo');

Check if validation was successful and field has a value, defaults to checking the current "topic".

  optional
  $validation = $validation->optional('foo');

Change validation "topic".

  param
  my $value = $validation->param('foo');

Access validated values. If there are multiple values sharing the same name, and you want to access more than just the last one, you can use "every_param".

  passed
  my $names = $validation->passed;

Return a list of all names for values that passed validation.

  # Names of all values that passed
  say for @{$validation->passed};

  required
  $validation = $validation->required('foo');

Change validation "topic" and make sure a value is present and not an empty string.

AUTOLOAD
In addition to the "ATTRIBUTES" and "METHODS" above, you can also call validation checks provided by "validator" on Mojolicious::Validator::Validation objects, similar to "check".

  # Call validation checks
  $validation->required('foo')->size(2, 5)->like(qr/^[A-Z]/);
  $validation->optional('bar')->equal_to('foo');
  $validation->optional('baz')->in(qw(test 123));

  # Longer version
  $validation->required('foo')->check('size', 2,5)->check('like', qr/^[A-Z]/);
