Python Web Development Techdegree Graduate 14,810 PointsHow to rebuild Learning site for new Django 1.10.2?
Learning site works with Django 1.8.4 well, but doesn't with new Django 1.10.2.
Throws exceptions "NoReverseMatch" for views.

Python Web Development Techdegree Graduate 28,600 PointsReversing by dotted path was deprecated in Django 1.10. Just naming the view will solve the problem.

Treehouse Guest TeacherAh, yeah, IIRC, there was something like {% url "views.hello_world" %} in a template, right? That's no longer supported as of Django 1.10, so you'll need to give the URL a name and use that instead, like Tatiana Vasilevskaya mentioned.
Kenneth Love
Treehouse Guest TeacherIf that's what you named the URL. url(r"^hello/$", views.hello_world, name="hello_world") for example.

Python Web Development Techdegree Graduate 14,810 PointsThanks to Tatiana Vasilevskaya and Kenneth Love !
OK, so if someone else is interested in how to correct learning_site to use with Django 1.10:
1 In learning_site/urls.py add name to hello_world.
from django.conf.urls import include, url
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from . import views
urlpatterns = [
url(r'^courses/', include('courses.urls', namespace='courses')),
url(r'^admin/', include(admin.site.urls)),
url(r'^$', views.hello_world, name='hello_world'),
]
urlpatterns += staticfiles_urlpatterns()
2 in layout.html change dot notation for hello_world to the name added.
{% load static from staticfiles %}
<!doctype html>
<html>
<head>
<title>{% block title %}{% endblock %}</title>
<link rel="stylesheet" href="{% static 'css/layout.css' %}">
</head>
<body>
<div class="site-container">
<nav>
<a href="{% url 'hello_world' %}">Home</a>
<a href="{% url 'courses:list' %}">Courses</a>
</nav>
{% block content %}{% endblock %}
</div>
</body>
</html>

Python Web Development Techdegree Graduate 14,810 PointsOk.
- I use PyCharm.
- If i specify django version for my venv to 1.8.4 or 1.8.7 (You used 1.8.7 in video) - everything works like in video.
- If i instal latest django 1.10.2 to my venv - i get exceptions (i guess while rendering templates).
Run manage.py Task:
Exception in browser:
Same exception i get for all views.

Python Web Development Techdegree Graduate 14,810 PointsHi, Tatiana Vasilevskaya ! What do you mean saying naming? Naming in views.py?
Tatiana Vasilevskaya
Python Web Development Techdegree Graduate 28,600 PointsTatiana Vasilevskaya
Python Web Development Techdegree Graduate 28,600 PointsSorry, naming the view url in urls.py and then use this name, when reversing to it.
