class celery.bin.base.CeleryOption(*args, **kwargs)

Customized option for Celery.

get_default(ctx, *args, **kwargs)

Get the default for the parameter. Tries Context.lookup_default() first, then the local default.

参数:

• ctx -- Current context.

• call -- If the default is a callable, call it. Disable to return the callable instead.

在 8.0.2 版本发生变更: Type casting is no longer performed when getting a default.

在 8.0.1 版本发生变更: Type casting can fail in resilient parsing mode. Invalid defaults will not prevent showing help text.

在 8.0 版本发生变更: Looks at ctx.default_map first.

在 8.0 版本发生变更: Added the call parameter.

class celery.bin.base.CommaSeparatedList

convert(value, param, ctx)
