2. Adding __repr__() to models
|
||
|
|
|
||
|
|
Although it's not a strict requirement, each model should have a ``__repr__()``
|
||
|
|
method to return a "human-readable" representation of the object. Do this not
|
||
|
|
only for your own sanity when dealing with the interactive prompt, but also
|
||
|
|
because objects' representations are used throughout Django's
|
||
|
|
automatically-generated admin.
