NAME

Mango::Database - MongoDB database

SYNOPSIS

  use Mango::Database;

  my $db = Mango::Database->new(mango => $mango);
  my $collection = $db->collection('foo');
  my $gridfs     = $db->gridfs;

DESCRIPTION

Mango::Database is a container for MongoDB databases used by Mango.

ATTRIBUTES

Mango::Database implements the following attributes.

mango

  my $mango = $db->mango;
  $db       = $db->mango(Mango->new);

Mango object this database belongs to. Note that this reference is usually weakened, so the Mango object needs to be referenced elsewhere as well.

name

  my $name = $db->name;
  $db      = $db->name('bar');

Name of this database.

METHODS

Mango::Database inherits all methods from Mojo::Base and implements the following new ones.

collection

  my $collection = $db->collection('foo');

Get Mango::Collection object for collection.

collection_names

  my $names = $db->collection_names;

Names of all collections in this database. You can also append a callback to perform operation non-blocking.

  $db->collection_names(sub {
    my ($db, $err, $names) = @_;
    ...
  });
  Mojo::IOLoop->start unless Mojo::IOLoop->is_running;

command

  my $doc = $db->command(bson_doc(text => 'foo.bar', search => 'test'));
  my $doc = $db->command(bson_doc(getLastError => 1, w => 2));
  my $doc = $db->command('getLastError', w => 2);

Run command against database. You can also append a callback to run command non-blocking.

  $db->command(('getLastError', w => 2) => sub {
    my ($db, $err, $doc) = @_;
    ...
  });
  Mojo::IOLoop->start unless Mojo::IOLoop->is_running;

dereference

  my $doc = $db->dereference($dbref);

Resolve database reference. You can also append a callback to perform operation non-blocking.

  $db->dereference($dbref => sub {
    my ($db, $err, $doc) = @_;
    ...
  });
  Mojo::IOLoop->start unless Mojo::IOLoop->is_running;

gridfs

  my $gridfs = $db->gridfs;

Get Mango::GridFS object.

stats

  my $stats = $db->stats;

Get database statistics. You can also append a callback to perform operation non-blocking.

    ...
  });
  Mojo::IOLoop->start unless Mojo::IOLoop->is_running;
