class thunderbird_accounts.celery.base.DatabaseTask

Bases: DjangoTask

Celery task base that retries transient database failures.

max_retries = 8

Maximum number of retries before giving up. If set to None, it will never stop retrying.

ignore_result = False

If enabled the worker won’t store task state and return values for this task. Defaults to the task_ignore_result setting.

priority = None

Default task priority.

rate_limit = None

Rate limit for this task type. Examples: None (no rate limit), ‘100/s’ (hundred tasks a second), ‘100/m’ (hundred tasks a minute),`’100/h’` (hundred tasks an hour)

reject_on_worker_lost = None

Even if acks_late is enabled, the worker will acknowledge tasks when the worker process executing them abruptly exits or is signaled (e.g., :sig:`KILL`/:sig:`INT`, etc).

Setting this to true allows the message to be re-queued instead, so that the task will execute again by the same worker, or another worker.

Warning: Enabling this can cause message loops; make sure you know what you’re doing.

request_stack = <celery.utils.threads._LocalStack object>

Task request stack, the current request will be the topmost.

serializer = 'json'

The name of a serializer that are registered with kombu.serialization.registry. Default is ‘json’.

store_errors_even_if_ignored = False

When enabled errors will be stored even if the task is otherwise configured to ignore results.

track_started = False

If enabled the task will report its status as ‘started’ when the task is executed by a worker. Disabled by default as the normal behavior is to not report that level of granularity. Tasks are either pending, finished, or waiting to be retried.

Having a ‘started’ status can be useful for when there are long running tasks and there’s a need to report what task is currently running.

The application default can be overridden using the task_track_started setting.

typing = True

Enable argument checking. You can set this to false if you don’t want the signature to be checked when calling the task. Defaults to app.strict_typing.

class thunderbird_accounts.celery.base.PatientExternalServiceTask

Bases: DatabaseTask

Maximum number of retries before giving up. If set to None, it will never stop retrying.
