A simple Luigi app to connect django and luigi.

Project description

=====
luigi
=====

Luigi is a simple Django app to be able to link Django to the workflow manager luigi.

Quick start
-----------

1. Add 'django_luigi' to you INSTALLED_APPS settings like this::

INSTALLED_APP = [...
'django_luigi',
]

2. Create your `app` and `models` in Django as usual

3. Run `python manage.py migrate` to create the models.

You can know create objects in your luigi pipeline.

Assuming a django model Test in the test app with two CharField, item1, and item2, properly migrated

.. code-block:: python
from django.db import models

class Test(models.Model):
item1 = models.CharField(max_length=120)
item2 = models.CharField(max_length=120)

Here is a minimal example of a job to copy data to database using Django :

.. code-block:: python

import luigi
from django_luigi.django import ToORM

class TestTask(ToORM):

django_root = 'path_to_your_django_root' # Where manage.py is
settings_path = 'my_site.settings'

model = 'Test'
app = 'test'

def rows(self):
for row in [("item1", "property1"), ("item2", "property2")]:
yield row

if __name__ == '__main__':
task = TestTask()
luigi.build([task], local_scheduler=True)


In the above examples, the data that needs to be copied was directly provided by
overriding the rows method. Alternately, if the data comes from another task, the
modified example would look as shown below:

.. code-block:: python

import luigi
from django_luigi.django import ToORM
from luigi.mock import MockTarget

class BaseTask(luigi.Task):
def output(self):
return MockTarget("BaseTask")

def run(self):
out = self.output().open("w")
TASK_LIST = ["item%d\\tproperty%d\\n" % (i, i) for i in range(1,3)]
for task in TASK_LIST:
out.write(task)
out.close()

class TestTask(ToORM):

django_root = 'path_to_your_django_root' # Where manage.py is
settings_path = 'my_site.settings'

model = 'Test'
app = 'test'

def requires(self):
return BaseTask()

if __name__ == '__main__':
task1, task2 = TestTask(), BaseTask()
luigi.build([task1, task2], local_scheduler=True)
