This is where he should take the variable

from django.shortcuts import render, get_object_or_404, redirect

from . models import *

class ObjectDetailMixin:
  model = None
  template = None

  def get(self, request, slug):
    	obj = get_object_or_404(self.model, slug__iexact=slug)
    	return render(request, self.template, context={self.model.__name__.lower(): obj, 'admin_obj': obj})





class ObjectCreateMixin:
  model_form = None
  template = None


  def get(self,request):
    form = self.model_form()
    return render(request, self.template, context={'form': form})

  def post(self, request):
    bound_form = self.model_form(request.POST)

    if bound_form.is_valid():
      new_obj = bound_form.save()
      return redirect(new_obj)

    return render(request, self.template, context={'form': bound_form})





class ObjectUpdateMixin:

  def get(self, request, slug):
    obj = self.model.objects.get(slug__iexact=slug)
    bound_form = self.model_form(instance=obj)
    return render(request, self.template, context={'form': bound_form, self.model.__name__.lower(): obj})

  def post(self, request, slug):
    obj = self.model.objects.get(slug__iexact=slug)
    bound_form = self.model_form(request.POST, instance=obj)

    if bound_form.is_valid():
      new_obj = bound_form.save()
      return redirect(new_obj)

    return render(request, self.template, context={'form': bound_form, self.model.__name__.lower(): obj})




class ObjectDeleteMixin:

  def get(self, request, slug):
    obj = self.model.objects.get(slug__iexact=slug)
    return render(request, self.template, context={self.model.__name__.lower(): obj})

  def post(self, request, slug):
    obj = self.model.objects.get(slug__iexact=slug)
    obj.delete()
    return redirect(reverse(self.redirect_url))
