NAME Catalyst::TraitFor::Controller::DoesExtPaging - Paginate DBIx::Class::ResultSets for ExtJS consumption VERSION version 0.093370 SYNOPSIS package MyApp::Controller; use Moose; BEGIN { extends 'Catalyst::Controller' } # a single with would be better, but we can't do that # see: http://rt.cpan.org/Public/Bug/Display.html?id=46347 with 'Catalyst::TraitFor::Controller::DBIC::DoesPaging'; with 'Catalyst::TraitFor::Controller::DoesExtPaging'; sub people :Local { # ... my $json = $self->ext_paginate($paginated_rs); # ... } sub people_lite :Local { # ... my $json = $self->ext_paginate($paginated_rs, sub { my $person = shift; return { first_name => $person->first_name, last_name => $person->last_name, } }); # ... } # this will call the 'foo' method on each person and put the returned # value into the datastructure sub people_more_different :Local { # ... my $json = $self->ext_paginate($paginated_rs, 'foo'); # ... } sub programmers_do_it_by_hand :Local { # ... my $data = [qw{foo bar baz}]; my $total = 10; my $json = $self->ext_parcel($data, $total); # ... } # defaults total to amount of items passed in sub some_programmers_do_it_by_hand_partially :Local { # ... my $data = [qw{foo bar baz}]; my $json = $self->ext_parcel($data); # ... } DESCRIPTION This module is mostly for sending DBIx::Class paginated data to ExtJS based javascript code. METHODS ext_paginate my $resultset = $self->model('DB::Foo'); my $results = $self->paginate($resultset); my $json = $self->ext_paginate($resultset); my $json_str = to_json($json); Description Returns a structure like the following from the ResultSet: { data => \@results, total => $count_before_pagination } Valid arguments are: rs - paginated ResultSet to get the data from coderef - any valid scalar that can be called on the result object ext_parcel my $items = [qw{foo bar baz}]; my $total = 7; my $json = $self->ext_parcel($data, $total); my $json_str = to_json($json); Description Returns a structure like the following: { data => [@{$items}], total => $total || scalar @{$items} } Valid arguments are: list - a list of anything you want to be in the data structure total - whatever you want to say the total is. Defaults to size of the list passed in. CONFIG VARIABLES root Sets the name of the root for the data structure. Defaults to data. total_property Sets the name for the total property for the data structure. Defaults to total. SEE ALSO Catalyst::Controller::Role::DBIC::DoesPaging.
