| ============ | |
| Module that makes django admin handle OneToOneFields in a better way. | |
| A common use case for one-to-one relationships is to "embed" a model | |
| inside another one. For example, a Person may have multiple foreign |

The major tradeoffs between using UUIDs and sequential integers as primary keys fall into two categories:
And I'll say up front: I believe UUIDs are rarely a good idea, both for the reasons I've listed here, and the fact that I've almost never seen them used in the wild.

| # Python 2's %-formatting will "upgrade" the format string to unicode if an | |
| # argument is unicode, where str.format(…) will downgrade unicode arguments to | |
| # bytes. This leads to unnecessarily fragile code, as very small programmer | |
| # mistakes can cause show-stopping Unicode-related exceptions. | |

| * ezdirective makes it possible to create AngularJS directives without | |
| * checking the documentation. | |
| * | |
| * Sane defaults are used (`restrict: 'E'` and `scope: {}`), and the link() | |
| * function is injected using $injector, which which can also inject the | |
| * `$scope`, `$elem`, and `attrs` that a normal directive link function would | |
| * expect. | |
