Choices on steroids

[](https://travis-ci.org/krotkiewicz/choose)

Basic usage:

```python
>>> class Types(choose.Choices):
>>> BAR = choose.Choice('foo_bar', 'Foo Bar')
>>> BAZ = choose.Choice('foo_baz', 'Foo Baz')
>>> Types.BAR
'foo_bar'
>>> Types.BAR.text
'Foo Bar'
>>> Types.items()
(('foo_bar', 'Foo Bar'), ('foo_baz', 'Foo Baz'))
>>> Types.keys()
('foo_bar', 'foo_baz')
>>> Types.values()
('Foo Bar', 'Foo Baz')
>>> 'foo_bar' in Types
True
```

Extended usage:

```python
>>> class Types2(choose.Choices):
>>> BAR = choose.Choice('foo_bar', 'Foo Bar', default=False)
>>> BAZ = choose.Choice('foo_baz', 'Foo Baz', default=False)
>>> FOO = choose.Choice('foo_foo', 'Foo Foo', default=True)
>>>
>>> @classmethod
>>> def get_default(cls):
>>> return next(
>>> (item for item in cls.keys() if item.opts.default is True),
>>> None,
>>> )
>>>
>>> Types2.BAR.opts.default
False
>>> Types2.BAR.opts.not_existing_attr is None
True
>>> 'foo_bar' == Types2.get_default()
False
>>> Types2.BAR == Types2.get_default()
False
>>> 'foo_foo' == Types2.get_default()
True
>>> Types2.FOO == Types2.get_default()
True
```

Usage in Django:

```python
class AModel(models.Model):
class AChoices(choose.Choices):
X = choose.Choice('x', 'X')
Y = choose.Choice('y', 'Y')

choice = models.CharField(max_length=63, choices=AChoices.items())
```
