public / sequelize

Usually when adding to a `foobar.getBla()` a where param
like `foobar.getBla({where: {x: "y"}})` it should extend
the existing where param (`"id": id`) with the additional
where param.
This didn't work for belongsTo associations until now.

PostgreSQL will no longer try to split regclass identifiers for default values.

Added special field for describing tables with Postgres, this will give us ...

findOrCreate returns additional flag to tell whether the entry was found or created

…NUM values directly, also made a array conversion tool for postgres' querygenerator.

Add model validations option

Plus a test for that

Also add a test for it

Instead of a hash called __model with the model validation errors, the
model validation errors are now alongside the field validation keys of
the hash, named after the validation's key in the validate array. To be
as consistent as possible, the value is an array even though it will
only ever have one member. The structure is set to change in 2.0.

Example: where there was a model validation set up like

	validate: {
		xnor: function() {
			if (this.field1 === null) === (this.field2 === null) {
				throw new Error('require both or neither')
			}
		}
	}

and field1 and field2 have some validations, validate() might return
something like

	{
		field1: [
			'must be an email address',
			'email address must be @example.com'
		],
		xnor: ['require both or neither']
	}

Added DOA Getters and Setters

As discussed on IRC. Also add task for 2.0 to change the validate()
output structure.

The existing but unused (as far as I could tell) DAO option `validate`
can now have member methods which will be called with the model object's
context after the other (field-specific) validations.

Only custom functions are allowed (since isInt etc wouldn't make sense
in this context).

As with other custom validations, they are deemed to pass if they throw
no error, or fail if an error is thrown.

Any error messages collected are added to a '_' member array of the
validation result object, alongside the arrays named after any fields
whose validations failed.

Example:

	var Pub = Sequelize.define('Pub', {
		name: { type: Sequelize.STRING },
		address: { type: Sequelize.STRING },
		latitude: {
			type: Sequelize.INTEGER,
			allowNull: true,
			defaultValue: null,
			validate: { min: -90, max: 90 }
		},
		longitude: {
			type: Sequelize.INTEGER,
			allowNull: true,
			defaultValue: null,
			validate: { min: -180, max: 180 }
		},
	}, {
		validate: {
			xorCoords: function() {
				if ((this.latitude === null) === (this.longitude === null)) {
					throw new Error('Require either both latitude and longitude or neither')
				}
			}
		}
	})

In this simple case an object fails validation if latitude or longitude
is given, but not both. If we try to build one with an out of range
latitude and no longitude, `raging_bullock_arms.validate()`, might
return

	{
		'latitude': ['Invalid number: latitude'],
		'_': ['Require either both latitude and longitude or neither']
	}

A test is included.
