django-better-repr 1.0.7

Installation

pip install django-better-repr

If you want to automatically improve the repr of all models in your project then add django_better_repr to your installed apps.

# settings.py
INSTALLED_APPS = [
   ...,
   'django_better_repr',
   ...,
]

Want to customize which apps get configured but don’t want to decorate each class individually? Head on down to the Configuration section.

How to use:

The repr logic in this library is designed to produce the smallest, most meaningful repr possible for your Django models. That means that fields which aren’t set won’t show up in the repr. This should reduce noise and let you get the most value out of your reprs.

from django_better_repr import better_repr

@better_repr
class MyDjangoModel(models.Model):
    my_field = models.CharField(max_length=16)

Or, if class inheritance is more your speed:

from django_better_repr.bases import BetterRepr

class MyDjangoModel(BetterRepr, models.Model):
    my_field = models.CharField(max_length=16)

Then load up your favorite shell and run:

MyDjangoModel.objects.create(my_field='Hello, world!')
>>> MyDjangoModel(my_field='Hello, world!')

If your model has a lot of fields then the repr will automatically switch to pretty printing. This can be configured via settings.

Configuration

If you want to customize the behavior of the library, below are all the options.

# settings.py
BETTER_REPR_CONFIG = {
   'ENABLE_MULTILINE_REPRS': True,  # bool (default: True), whether or not to allow multiline reprs
   'SINGLE_LINE_PARTS_LIMIT': 4,  # int (default: 4), the number of fields a repr can have before switching to multi line
   'MULTILINE_WHITESPACE': '\t',  # str (default: '\t'), the whitespace string to use for multiline reprs
   'AUTO_CONFIGURE_INCLUDE_MODELS': [],  # list (default: a sentinel for all models), which models to auto include if the auto configuration application is added to INSTALLED_APPS
   'AUTO_CONFIGURE_EXCLUDE_MODELS': [],  # list (default: []), which models to exclude from the auto setup if the auto configuration application is added to INSTALLED_APPS
   'EXCLUDE_DEFERRED_FIELDS': True,  # bool (default: True), whether or not to exclude deferred fields (https://docs.djangoproject.com/en/4.2/ref/models/querysets/#django.db.models.query.QuerySet.defer) from the repr
}
