Documentation
-------------

The purpose of this package is to handle in some way mentions to users in a text field of a model. You can choose the model you want, the field you want to listen to mentions, the pattern you use to codify the mention and the callback to notify to your app.

The package will notify to callback function each time there is a mention in this field of the model. Then you can act accordingly on your application requisites.

The full documentation is at https://exo-mentions.readthedocs.io.

Quickstart
----------

Install django-exo-mentions::

pip install django-exo-mentions

=====
Usage
=====

To use django-exo-mentions in a project, add it to your `INSTALLED_APPS`:

.. code-block:: python

INSTALLED_APPS = (
...
'exo_mentions',
...
)

Define a signal for the callback

.. code-block:: python

from django.dispatch import receiver
from django.core.signals import request_finished

@receiver(request_finished)
def post_detect_mention_callback(sender, **kwargs):
""" You will receive information of the mention
user_from: kwargs.get('user_from')
User that mentions
object_pk: kwargs.get('object_pk')
User's Pk that has been mentioned
target: kwargs.get('target')
The object where the mention was made
"""

# Your code here

Register a model and field in which you want to detect mentions.
You can override the pattern if you want.

.. code-block:: python

from django.apps import AppConfig
from exo_mentions.registry import register

class MyAppConfig(AppConfig):
name = 'myapp'

def ready(self):
model = Post
field = 'description'
callback = post_detect_mention_callback

register(model, field, callback)

At this point the library will notify to the callback each time there is a mention in the field of the registered model. Thats all! :)

.. code-block:: python

def register(model, field, callback, pattern):
"""
This method handles the mentions about the model in the field and notify to the callback when there is any mention

Parameters
----------
model : Models
The model to register for detect mentions
field : str
Field of the model to detect mentions
callback : function
Callback function to notify when there are mentions
pattern : regular expression
The pattern to codify the mentions (default r'class="mention" data-user=[\'"]?([^\'" >]+)')

"""


Running Tests
-------------

Does the code actually work?

Docker, Compose, and Tox are used to approximate the environment that Travis CI, Code Climate, and Coveralls all run when you push. This will allow you to test your code against multiple versions of Python (3.4, 3.5, 3.6, 3.7) locally before pushing it or even committing it. For more information about how to get Docker, please visit `documentation
https://docs.docker.com/install/linux/docker-ce/ubuntu/`_.

To run everything (this will take a while the first time you run it, but subsequent runs will be quick):

$ docker build -t django-exo-mentions/tox:latest .
