From: Alexander Hartmaier Date: Fri, 22 Oct 2010 12:47:10 +0000 (+0200) Subject: Warn instead of throwing an exception if a key is neither a column, a relationship... X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;h=882e0965d8ecbf0320905b794bbbdbc7cc3582f7;p=chaz%2Fp5-DBIx-Class-ResultSet-RecursiveUpdate Warn instead of throwing an exception if a key is neither a column, a relationship nor a many-to-many helper. also added a new api to the resultset api which is able to suppress the warnings when the second parameter is a hashref containing a key named unknown_params_ok with a true value. --- diff --git a/Changes b/Changes index f90c739..3de0d2c 100644 --- a/Changes +++ b/Changes @@ -1,6 +1,8 @@ Revision history for DBIx::Class::ResultSet::RecursiveUpdate {{ $NEXT }} + - Warn instead of throwing an exception if a key is neither + a column, a relationship nor a many-to-many helper. 0.20 2010-10-19 09:25:33 Europe/Vienna - Support has_many relationships with multi-column primary keys diff --git a/dist.ini b/dist.ini index f6eaa7c..d98cf83 100644 --- a/dist.ini +++ b/dist.ini @@ -43,3 +43,4 @@ List::MoreUtils = 0.22 [Prereqs / TestRequires] Test::More = 0.88 +Test::Warn = 0.20 diff --git a/lib/DBIx/Class/ResultSet/RecursiveUpdate.pm b/lib/DBIx/Class/ResultSet/RecursiveUpdate.pm index ca0a771..6594748 100644 --- a/lib/DBIx/Class/ResultSet/RecursiveUpdate.pm +++ b/lib/DBIx/Class/ResultSet/RecursiveUpdate.pm @@ -2,17 +2,34 @@ use strict; use warnings; package DBIx::Class::ResultSet::RecursiveUpdate; + # ABSTRACT: like update_or_create - but recursive use base qw(DBIx::Class::ResultSet); sub recursive_update { - my ( $self, $updates, $fixed_fields ) = @_; + my ( $self, $updates, $attrs ) = @_; + + my $fixed_fields; + my $unknown_params_ok; + + # 0.21+ api + if ( defined $attrs && ref $attrs eq 'HASH' ) { + $fixed_fields = $attrs->{fixed_fields}; + $unknown_params_ok = $attrs->{unknown_params_ok}; + } + + # pre 0.21 api + elsif ( defined $attrs && ref $attrs eq 'ARRAY' ) { + $fixed_fields = $attrs; + } + return DBIx::Class::ResultSet::RecursiveUpdate::Functions::recursive_update( - resultset => $self, - updates => $updates, - fixed_fields => $fixed_fields + resultset => $self, + updates => $updates, + fixed_fields => $fixed_fields, + unknown_params_ok => $unknown_params_ok, ); } @@ -24,22 +41,25 @@ use List::MoreUtils qw/ any /; sub recursive_update { my %params = @_; my ( $self, $updates, $fixed_fields, $object, $resolved, - $if_not_submitted ) + $if_not_submitted, $unknown_params_ok ) = @params{ - qw/resultset updates fixed_fields object resolved if_not_submitted/}; + qw/resultset updates fixed_fields object resolved if_not_submitted unknown_params_ok/ + }; $resolved ||= {}; # warn 'entering: ' . $self->result_source->from(); carp 'fixed fields needs to be an array ref' - if $fixed_fields && ref($fixed_fields) ne 'ARRAY'; - my %fixed_fields; - %fixed_fields = map { $_ => 1 } @$fixed_fields if $fixed_fields; + if defined $fixed_fields && ref $fixed_fields ne 'ARRAY'; + if ( blessed($updates) && $updates->isa('DBIx::Class::Row') ) { return $updates; } if ( $updates->{id} ) { $object = $self->find( $updates->{id}, { key => 'primary' } ); } + + my %fixed_fields = map { $_ => 1 } @$fixed_fields + if $fixed_fields; my @missing = grep { !exists $updates->{$_} && !exists $fixed_fields{$_} } $self->result_source->primary_columns; @@ -122,11 +142,16 @@ sub recursive_update { } # unknown - # TODO: don't throw a warning instead of an exception to give users - # time to adapt to the new API - $self->throw_exception( + + # don't throw a warning instead of an exception to give users + # time to adapt to the new API + warn( "No such column, relationship, many-to-many helper accessor or generic accessor '$name'" - ); + ) unless $unknown_params_ok; + +#$self->throw_exception( +# "No such column, relationship, many-to-many helper accessor or generic accessor '$name'" +#); } # warn 'other: ' .
