reviewboard.search.signal_processor¶

The signal processor for Review Board search.

class SignalProcessor(*args, **kwargs)[source]¶

Bases: haystack.signals.BaseSignalProcessor

“Listens for signals and updates the search index.

This will listen for any signals that would affect the search index, and invokes a suitable Haystack callback to immediately update the data stored in the index.

This only updates the search index if:

1. Search is enabled.
2. The current search engine backend supports on-the-fly indexing.

save_signals = [(<class 'reviewboard.reviews.models.review_request.ReviewRequest'>, <django.dispatch.dispatcher.Signal object>, u'review_request'), (<class 'django.contrib.auth.models.User'>, <django.db.models.signals.ModelSignal object>, u'instance'), (<class 'reviewboard.accounts.models.Profile'>, <django.db.models.signals.ModelSignal object>, u'instance')][source]¶

delete_signals = [(<class 'reviewboard.reviews.models.review_request.ReviewRequest'>, <django.db.models.signals.ModelSignal object>), (<class 'django.contrib.auth.models.User'>, <django.db.models.signals.ModelSignal object>)][source]¶

__init__(*args, **kwargs)[source]¶

Initialize the signal processor.

Parameters:	*args (tuple) – Positional arguments to pass to the parent constructor. **kwargs (dict) – Keyword arguments to pass to the parent constructor.

can_process_signals[source]¶

Whether the signal processor can currently process signals.

setup()[source]¶

Register the signal handlers for this processor.

teardown()[source]¶

Unregister all signal handlers for this processor.

check_handle_save(instance_kwarg, **kwargs)[source]¶

Conditionally update the search index when an object is updated.

Parameters:	instance_kwarg (unicode) – The name of the instance parameter. **kwargs (dict) – Signal arguments. These will be passed to handle_save().

check_handle_delete(**kwargs)[source]¶

Conditionally update the search index when an object is deleted.

Parameters:	**kwargs (dict) – Signal arguments. These will be passed to handle_delete().

handle_save(**kwargs)[source]¶

Update the search index when an object is updated.

If there’s any error writing to the search backend, the error will be caught and logged.

Parameters:	**kwargs (dict) – Signal arguments. These will be passed to handle_save().

handle_delete(**kwargs)[source]¶

Update the search index when an object is deleted.

If there’s any error writing to the search backend, the error will be caught and logged.

Parameters:	**kwargs (dict) – Signal arguments. These will be passed to handle_save().
