Simple email confirmation for django model instances.

djeveric

    Simple email confirmation for django model instances with 
    [Django Rest Framework](https://www.django-rest-framework.org/).
    
    ## Usage
    
    ### Create a model
    
    Create a model class inheriting from `ConfirmableModelMixin` with a `ConfirmationField` and refer to a 
    `ConfirmationEmail` class like this:
    
    ```python
    from django.conf import settings
    from django.db import models
    
    from djeveric.emails import ConfirmationEmail
    from djeveric.fields import ConfirmationField
    from djeveric.models import ConfirmableModelMixin
    
    class MyModelConfirmationEmail(ConfirmationEmail):
        subject = "Please confirm"
        
        def get_body(self, context):
            return f"Use this link to confirm: http://my-frontend/confirm/{self.token}"
        
        def get_recipient(self) -> str:
            return self.instance.owner.email
    
    class MyModel(ConfirmableModelMixin, models.Model):
        owner = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
        is_confirmed = ConfirmationField(email_class=MyModelConfirmationEmail)
    ```
    
    When unconfirmed instances of the model are saved, djeveric sends a confirmation email to the specified address.
    
    
    ### Create a ViewSet
    
    To actually confirm a viewset, your backend needs a view set using the `ConfirmModelMixin`:
    
    ```python
    from rest_framework import viewsets
    
    from djeveric.views import ConfirmModelMixin
    
    
    class MyModelViewSet(ConfirmModelMixin, viewsets.GenericViewSet):
        queryset = MyModel.objects
    ```
    
    On a `POST /api/my-models/{pk}/confirm/` with `{"token": "THE TOKEN"}` as data the model instance will be confirmed.
