Где найти стандартные правила наименования url, class base view и методов моделей?
Все что хочешь в рамках PEP8
Я обычно делаю так:articles/models/article.py:# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import models


class Article(models.Model):
    title = models.CharField(max_lenght=32, verbose_name=_('name'))articles/views/article.py:# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.views import generic


class ArticleMixin(object):
    fields = ['title']
    model = Article
    paginate_by = 30

    def get_success_url(self):
        return reverse('articles_article_index')


class Index(ArticleMixin, generic.ListView):
    template_name = 'articles/index.html'


class Create(ArticleMixin, generic.CreateView):
    template_name = 'articles/create.html'


class Update(ArticleMixin, generic.UpdateView):
    template_name = 'articles/update.html'


class Delete(ArticleMixin, generic.DeleteView):
    template_name = 'articles/delete.html'


index = Index.as_view()
create = Create.as_view()
update = Update.as_view()
delete = Delete.as_view()articles/urls.py# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.conf.urls import url
from django.conf.urls import patterns

from articles.views import article

urlpatterns = patterns('',
                       url(r'^$', article.index, name='articles_article_index'),
                       url(r'^update/(?P<pk>[\w-]+)/$', article.update, name='articles_article_update'),
                       url(r'^delete/(?P<pk>[\w-]+)/$', article.delete, name='articles_article_delete'),
                       url(r'^create/$', article.create, name='articles_article_create'),
                       )
Посмотрите проекты на github-e, поучитесь как говориться у мастеров.
