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


Define a signal for the callback

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

from django.apps import AppConfig
from 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! :)

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

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=[\'"]?([^\'" >]+)')
