Get_Slug_Field() example for multiple slugs in Django 2.1?

I want to find a way to add multiple slugs from different models to one view.

Either with get_slug_field and get_object; or other ways are appreciated as well..

But please, take into consideration that this is Generic View in which I am looking for the solution.

If your generic view is of type View, then you could declare it with the ContextMixin and then def get_context_data(**kwargs) on the view. If your view is a TemplateView, ListView, DetailView, etc., then you can do def get_context_data(**kwargs) without having to use a mixin.

View

def get_context_data(**kwargs)

TemplateView

ListView

DetailView

def get_context_data(**kwargs)

Example using plain View and ContextMixin (you would need to do proper importing where necessary):

View

ContextMixin

models.py:

class ModelOne(models.Model):
slug = models.SlugField(default='', max_length=75)


class ModelTwo(models.Model):
slug = models.SlugField(default='', max_length=75)


Note: max_length defaults to 50; the 75 is arbitrary

views.py

class MyView(View, ContextMixin):

def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['slug_from_model_one'] = ModelOne.objects.get(...define your lookup...).slug
context['slug_from_model_two'] = ModelTwo.objects.get(...define your lookup...).slug
return context
