NAME ^

CGI::Application::Plugin::ExtJS - Convert paginated DBIx::Class::ResultSet's to JSON-style structures

VERSION ^

version 1.000001

SYNOPSIS ^

  use CGI::Application::Plugin::ExtJS ':all';

  sub people {
     # ...
     my $json = $self->ext_paginate($paginated_rs);
     # ...
  }

  sub people_lite {
     # ...
     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 {
     # ...
     my $json = $self->ext_paginate($paginated_rs, 'foo');
     # ...
  }

  sub programmers_do_it_by_hand {
     # ...
     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 {
     # ...
     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->schema->resultset('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.
