signals

✓ from fieldsignals import signals

Connect a signal to a specific field on a model. Place in AppConfig.ready().

from django.apps import AppConfig from fieldsignals import connect, post_save, pre_save class MyAppConfig(AppConfig): name = 'myapp' def ready(self): from myapp.models import MyModel connect(post_save, MyModel, 'my_field', receiver) def receiver(sender, instance, **kwargs): print(f"{sender} field changed: {instance}")

Debug

Known issues

gotchaSignal receivers must be connected after Django app setup (in AppConfig.ready()). Connecting at module level may cause race conditions.

fix

Always connect signals inside AppConfig.ready() or using ready() decorator.

affects: all

gotchaThe library only tracks field changes within the save() call. Model-level updates via queryset.update() do not trigger signals.

fix

Use Django's post_save signal or override save() for bulk updates if needed.

affects: all

deprecatedThe connect_signal() function was removed in 0.7.0. Use connect() directly.

fix

Replace connect_signal() with connect().

affects: >=0.7.0

breakingSignals no longer pass 'field' argument; they pass 'field_name' (string).

fix

Update receivers to expect field_name instead of field.

affects: >=0.8.0
