NAME

Maypole::Model:CDBI::FromCGI - Validate form input and populate Model objects

SYNOPSIS

   $obj = $class->create_from_cgi($r);
   $obj = $class->create_from_cgi($r, { params => {data1=>...}, required => [..],
                  ignore => [...], all => [...]);
   $obj = $class->create_from_cgi($h, $options); # CDBI::FromCGI style, see docs
 
   $obj->update_from_cgi($r);
   $obj->update_from_cgi($h, $options);
 
   $obj = $obj->add_to_from_cgi($r);
   $obj = $obj->add_to_from_cgi($r, { params => {...} } );
 
   # This does not work like in CDBI::FromCGI and probably never will :
   # $class->update_from_cgi($h, @columns);
 
 

DESCRIPTION

Provides a way to validate form input and populate Model Objects, based on Class::DBI::FromCGI.

METHODS

untaint_columns

Replicates Class::DBI::FromCGI method of same name :

   __PACKAGE__->untaint_columns(
     printable => [qw/Title Director/],
     integer   => [qw/DomesticGross NumExplodingSheep],
     date      => [qw/OpeningDate/],
   );
 
 

untaint_type

   gets the  untaint type for a column as set in "untaint_types"
 
 

cgi_update_errors

Returns errors that ocurred during an operation.

create_from_cgi

Based on the same method in Class::DBI::FromCGI.

Creates multiple objects from a cgi form. Errors are returned in cgi_update_errors

It can be called Maypole style passing the Maypole request object as the first arg, or Class::DBI::FromCGI style passing the Untaint Handler ($h) as the first arg.

A hashref of options can be passed as the second argument. Unlike in the CDBI equivalent, you can *not* pass a list as the second argument. Options can be :
 params --- hashref of cgi data to use instead of $r->params,
 required --- list of fields that are required
 ignore   --- list of fields to ignore
 all      --- list of all fields (defaults to $class->columns)

update_from_cgi

Replicates the Class::DBI::FromCGI method of same name. It updates an object and returns 1 upon success. It can take the same arguments as create_form_cgi. If errors, it sets the cgi_update_errors.

add_to_from_cgi

$obj->add_to_from_cgi($r[, $opts]);

Like add_to_* for has_many relationships but will add nay objects it can figure out from the data. It returns a list of objects it creates or nothing on error. Call cgi_update_errors with the calling object to get errors. Fatal errors are in the respective ``FATAL'' key.

validate_all

Validates (untaints) a hash of possibly mixed table data. Returns validated and errors ($validated, $errors). If no errors then undef in that spot.

validate_inputs

$self->validate_inputs($h, $opts);

This is the main validation method to validate inputs for a single class. Most of the time you use validate_all.

Returns validated and errors.

If no errors then undef in that slot.

Note: This method is currently experimental (in 2.11) and may be subject to change without notice.

classify_form_inputs

$self->classify_form_inputs($params[, $delimiter]);

Foreign inputs are inputs that have data for a related table. They come named so we can tell which related class they belong to. This assumes the form : $accessor . $delimeter . $column recursively classifies them into hashes. It returns a hashref.
