###TaffyDb for Titanium

Full credit goes to Ben Bahrenburg for the initial implementation of TaffyDB for Titanium, and to Ian Smith for the great TaffyDB library.

The current version of TiTaffyDb has a bug (I think the bug is in the older version of TaffyDB used by this module) that doesn't allow multiple dbs in the same module. There are query caching optimizations that make the data to be overwriten for the same query on two different dbs.

How the TiTaffyDb implementation goes deep integrated into TaffyDb, a simple update to the latest version was too much for me (I'm too lazy) so I stole some code from Ben and created a simpler wrapper for TaffyDb.

The syntax is cleaner (in my opinion) and the update to a future version of Taffy should be painless.

####TODO

  • Right now the only storage method is to a file. I will add, maybe :), storing to properties.
  • I tested it only on iOs, but the Ben's version was working just fine on Android so I see no reason why this version wouldn't. Anyway, I'll run some test and update this howto.

####How to

#####Create a database - plain simple The constructor accepts as argument the name of the store where the data wil reside.

var taffy = require('/taffydb4ti').taffy;

var my_db = new taffy('my_db_store_name');

my_db.insert({my_value:'first'});
my_db.insert({my_value:'second'});

my_db.save();

#####Create a database - passing taffydb settings More about Taffy settings (scroll to db.settings() )

var taffy = (require('/taffydb4ti').taffy;

var my_db = new taffy('my_db_store_name',{onInsert: function(){alert('We had an insert!')}});

my_db.insert({my_value:'first'});
my_db.insert({my_value:'second'});

my_db.save();

#####Save location - taffFolder and taffParentFolder. By default, save() will write the files to Ti.Filesystem.applicationDataDirectory/titaffydb. You can specify a full directory path with taffFolder or simply choose to keep the titaffydb directory name but select a differnt parent with taffParentFolder. This is useful if your database is a cache and you want it to live, for instance, in Ti.Filesystem.applicationCacheDirectory.

These two properties can be set through the settings when instanciating a taffy db.

var taffy = (require('/taffydb4ti').taffy;

var my_db = new taffy('my_db_store_name',{ taffParentFolder: Ti.Filesystem.applicationCacheDirectory });

my_db.insert({my_value:'first'});
my_db.insert({my_value:'second'});

my_db.save();

#####Create a database - autocommit This setting will autosave each change you are doing to the database. While handy, if you have many operation on the the db I suggest not to use it and call db.save() yourself. Of course autocommit can be used together with taffy settings.

var taffy = (require('/taffydb4ti').taffy;

var my_db = new taffy('my_db_store_name',{autocommit:true});

my_db.insert({my_value:'first'});
my_db.insert({my_value:'second'});

// no need for my_db.save() anymore;

####License TaffyDB is licensed under the BSD licence type.

TiTaffyDb seems to be under Apache2.

As long as you respect the above licenses I don't care what you do with the code.

Just have fun :)
