DJ CRUD Update?

Roman Kitaev, так у меня при создании поста все норм, а при обновление (ObjectUpdateMixin) выдает ошибку

DJ CRUD Update?

Roman Kitaev, может дело в миксине utils.py

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})



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:
	model = None
	model_form = None
	template = None

	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)

Roman Kitaev, get () получил неожиданный аргумент ключевого слова 'slug'
и что это значит

Миксин в Django?

Спасибо!
Убрал

Миксин в Django?

Дело не HTML'ле окозалось, а в utils.py

from django.shortcuts import render
from django.shortcuts import get_object_or_404

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})

Миксин в Django?

Я новичок в этом деле. Так что прошу прошения у Senior'ов

Миксин в Django?

Всё! Работает!
Оказывается надо было написать не конкретное название модели, а self.model

from django.shortcuts import render
from django.shortcuts import get_object_or_404

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})

Поправить миксин?

Сергей Горностаев, вы не могли бы помочь мне? Спрашивайте какие файлы нужны, я все покажу и расскажу

Поправить миксин?

Сергей Горностаев, ранше работало все "до миксина"

Поправить миксин?

Сергей Горностаев, но у меня есть теги

Поправить миксин?

Теперь теги не работают

Сергей Горностаев, можно подробнее

Панель администратора?

Что переписать?

Почему не работает код (JavaScript)?

А почему раньше таких проблем не было?
