Mango::Database - MongoDB database

       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.

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

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

   build_write_concern
         my $concern = $db->build_write_concern;

       Build write concern based on l</"mango"> settings.

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

       Build Mango::Collection object for collection.

   collection_names
         my $names = $db->collection_names;

       Names of all collections in this database. You can filter the results by using the same arguments as for
       "list_collections". 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;

       Build Mango::GridFS object.

   list_collections
         # return a cursor for all collections
         my $cursor = $db->list_collections;
         # only collections which name matchs a regex
         my $cursor = $db->list_collections(filter => { name => qr{^prefix} });
         # only capped collections
         my $cursor = $db->list_collections(filter => { 'options.capped' => 1 });
         # only the first 10 collections
         my $cursor = $db->list_collections(cursor => { batchSize => 10 });

       Returns a Mango::Cursor of all collections in this database. Each collection is represented by a document
       containing at least the keys "name" and "options". You can also append a callback to perform operation
       non-blocking.

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

   stats
         my $stats = $db->stats;

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

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