前言:

之前一直使用celery本来好好的,但是昨天更新代码的时候celery出了小问题,celery无法获取新写的tasks任务

后面通过查看官方文档有自动获取的方法。主要是 使用 autodiscover_tasks()

官网地址: http://docs.celeryproject.org/en/latest/reference/celery.html

autodiscover_tasks(self, packages=None,
                           related_name='tasks', force=False):
        """Auto-discover task modules.
        Searches a list of packages for a "tasks.py" module (or use
        related_name argument).
        If the name is empty, this will be delegated to fix-ups (e.g., Django).
        For example if you have a directory layout like this:
        .. code-block:: text
            foo/__init__.py
               tasks.py
               models.py
            bar/__init__.py
                tasks.py
                models.py
            baz/__init__.py
                models.py
        Then calling ``app.autodiscover_tasks(['foo', bar', 'baz'])`` will
        result in the modules ``foo.tasks`` and ``bar.tasks`` being imported.

        Arguments:
            packages (List[str]): List of packages to search.
                This argument may also be a callable, in which case the
                value returned is used (for lazy evaluation).
            related_name (str): The name of the module to find.  Defaults
                to "tasks": meaning "look for 'module.tasks' for every
                module in ``packages``."
            force (bool): By default this call is lazy so that the actual
                auto-discovery won't happen until an application imports
                the default modules.  Forcing will cause the auto-discovery
                to happen immediately.

看解释以后只要传入对应的tasks.py目录的路径就可以,因此我的代码就是

celery.autodiscover_tasks(['app.script','app.script.main'])

然后重启celery以后,新写的tasks任务就自动发现了
