Testing redirects to parameterized URLs when creating object

I have a view for creating blog posts which redirects the user to a form to fill the blog post content like this:
from django.views import View
from app.models import BlogPost
class CreateBlogPost(View):
def post():
new_post = BlogPost.objects.create()
return redirect(reverse('post_edit'), args=[new_post.id])
class EditBlogPost(View):
...
And my urls are the following:
from django.urls import path
from app.views import CreateBlogPost
urlpatterns = [
path('post', CreateBlogPost.as_view(), name='post_create'),
path('post/<int:pk>/edit', EditBlogPost.as_view(), name='post_edit')
]
I would like to: test the CreateBlogPost by asserting that it redirects to post/<some_id>/edit.
I've tried: using the method assertRedirects from django's SimpleTestCase, but couldn't find a way to make this work.
I'm also using pytest-django, in case that's relevant.

my Django DayArchiveView is not detected in urls.py

I created several date-based views in Django, and while views for year and month function as expected, the view to display days is not detected. For instance, if I try to get /balance/2018/, or /balance/2018/04/ the views will be displayed, while /balance/2018/04/02 will fail. I understand that the problem must be with urls.py configuration, but I just cannot find it in documentation. I also tried passing day_format='%d' to as_view method, without any results.
my urls.py file
from django.urls import path, re_path
from .views import ArticleYearArchiveView, ArticleMonthArchiveView, ArticleDayArchiveView
from . import views
urlpatterns = [
path('', views.index, name='index'),
path(r'<int:year>/<int:month:>/<int:day>/', views.ArticleDayArchiveView.as_view(day_format='%d'), name='show_day'),
path(r'<int:year>/<int:month>/', views.ArticleMonthArchiveView.as_view(month_format='%m'), name='show_month'),
path(r'<int:year>/', views.ArticleYearArchiveView.as_view(), name='show_year'),
]
my views.py file
from django.shortcuts import render
from django.views.generic.dates import YearArchiveView, MonthArchiveView, DayArchiveView
from django.http import HttpResponse
from django.db.models import Sum
from .models import Category, Article

def index(request):
num_of_articles = Article.objects.all().count()
num_of_categories = Category.objects.all().count()
return render(request, 'index.html', context = {
'num_of_articles':num_of_articles,
'num_of_categories':num_of_categories})
class ArticleYearArchiveView(YearArchiveView):
queryset = Article.objects.all()
date_field = 'financial_day'
make_object_list = True
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['summation'] = Article.objects.all().filter(financial_day__year=kwargs['year'].year).aggregate(Sum('amount_of_money'))['amount_of_money__sum']
return context
class ArticleMonthArchiveView(MonthArchiveView):
queryset = Article.objects.all()

#Here it'll show ARTICLE DETAILS for a given SLUG url
def show_article(request, article_slug):
response = "You are looking at the article %s."
return HttpResponse(response % article_slug)
Error text is:
Page not found (404)
Request Method: GET
Request URL: http://localhost:8000/balance/2018/04/02
Using the URLconf defined in spendings_calculator.urls, Django tried these URL patterns, in this order:
admin/
balance/ [name='index']
balance/ <int:year>/<int:month:>/<int:day>/ [name='show_day']
balance/ <int:year>/<int:month>/ [name='show_month']
balance/ <int:year>/ [name='show_year']
The current path, balance/2018/04/02, didn't match any of these.

You have a stray : after month - <int:month:>. Remove it:
path(r'<int:year>/<int:month>/<int:day>/', views.ArticleDayArchiveView.as_view(day_format='%d'), name='show_day'),
Also, note that you are defining the URL for balance/2018/04/02/ (with a trailing slash) but you are going to http://localhost:8000/balance/2018/04/02 (without a trailing slash). Once you have fixed the typo above, Django should redirect you to the URL with the trailing slash.

Import a class into the urls.py in Django

In the last few weeks I've switched from developing an application that processes a simple XML file, then writes its contents to an Oracle DB (cx_Oracle) and outputs in HTML, to using a Django framework. The Django framework switch wasn't necessary, but since I have an opportunity to develop something by using Django, I thought why not as it is a new area for me and can't damage my CV.
Anyway, I'm having issues with knowing what to write in my urls.py file when importing a Class from the views.py file. Here are the current contents:
urls.py
from myproj.views import Pymat_program
pymatProgram = Pymat_program()
urlpatterns = (
url(r'^pymat/$', pymatProgram.abc),
)
views.py
class Pymat_program:
def abc(self, request):
test = "<html><body>Random text.</body></html>"
return HttpResponse(test)
I've tried various permutations of using request, not using request, and also how the class is called in the url tuple, all to no avail. When I use a definition outside of the class (i.e. not in any class), then this is correctly displayed in HTML.

You don't want to wrap your program in a class. (In general, in Python you should treat modules like, say, Java might treat classes with static members only.)
There are two approaches, really:
Function-based views
urls.py
from myproj.views import abc_view
urlpatterns = (
url(r'^pymat/$', abc_view),
)
views.py
def abc_view(request):
test = "<html><body>Random text.</body></html>"
return HttpResponse(test)
Class-based views
urls.py
from myproj.views import AbcView
urlpatterns = (
url(r'^pymat/$', AbcView.as_view()),
)
views.py
from django.views.generic import View
class AbcView(View):
def get(self, request, *args, **kwargs):
test = "<html><body>Random text.</body></html>"
return HttpResponse(test)

Since you are using class based views in Django, so you have to call this class in URL like:
from myproj.views import Pymat_program
pymatProgram = Pymat_program()
urlpatterns = (
url(r'^pymat/$', pymatProgram.as_view()),
)
and then use get or post methods name in class like:
class Pymat_program:
model = ModelName
def post(self, request, *args, **kwargs):
....
2nd way is to use function based views:
urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^articles/2003/$', views.view_name),
]
views.py
from django.http import HttpResponse
import datetime
def view_name(request):
now = datetime.datetime.now()
html = "<html><body>It is now %s.</body></html>" % now
return HttpResponse(html)
for more details look into class based views docs
