Django change url programmatically

Question

I have to page in my django powered website. index.html and books.html

I have this link to the books.html in my first page

<a href="books.html">books</a>

and this one is in books.html for getting back to the first page.

<a href="index.html">Home</a>

and my url conf is like this

urlpatterns = patterns('',
    url(r'^$', 'mysite.views.home', name='home'),
    url(r'^books.html/$', 'mysite.views.bookpage', name='books'),
    url(r'index.html/$', 'mysite.views.home', name='home'),
)

and views.py

def home(request):
        return render_to_response('index.html')

def bookpage(request):
        return render_to_response('books.html')

When I click on the second link to get back home. my url address looks like this

mysite.com/books.html/index.html/

How can I change url back to mysite.com/ when clicking on the second link in books.html?

sorry if the title is not appropriate. i didn't know what would be my question title

Update

I've deleted url(r'^index.html/$', 'mysite.views.home', name='home') from my url patterns and used <a href="{% url 'home' %}"> in the second page. But nothing happens when I click on that link

Is the view referenced in the sample `mysite.views`? or `azahra.views`? — Brandon Taylor, Mar 16 '15 at 17:10
Help me understand why you want/need `index.html` to point to the home view instead of `/` — Brandon Taylor, Mar 16 '15 at 17:12
I think there's something larger at fault if `/` isn't working to get you back to the site root. That should work no problem. — Brandon Taylor, Mar 16 '15 at 17:16

With Django don't write <a href="anything.html">. You should use url template tag for page addresses. More on url template tag here: https://docs.djangoproject.com/en/1.7/ref/templates/builtins/#url

Example: <a href="{% url 'home' %}">

In your urls.py you have ^books.html/$ and index.html/$. Notice the missing ^ before index? You may want to add it.
Don't use same name for different patterns in urls.py.

But nothing happens when I use `` – Ghasem Mar 16 '15 at 17:18
That's most likely because there are two patterns named "home" – Brandon Taylor Mar 16 '15 at 17:22
But it is in my urlconf. isn't it? – Ghasem Mar 16 '15 at 17:26
The problem is somewhere in my `js` codes. it works when I try it in a test `` tag. thank you – Ghasem Mar 16 '15 at 17:33

Two issues that have been missed in the other answers:

You're missing a ^ in your third URL: url(r'^index.html/$', 'azahra.views.home', name='home'),
You have two URLs with the same name='home'. One of them should be changed.

As mentioned, you should also be using {% url 'url_name' %} template tags, instead of hard-coding in your templates.

Also, unless your application is actually named mysite, you need to change that to reference your actual views...

What do you mean "nothing happens"? Do you get an error? – rnevius Mar 16 '15 at 17:23
No. there is no errors. its like you don't click at all! – Ghasem Mar 16 '15 at 17:25
Do you actually have an app called `mysite`? – rnevius Mar 16 '15 at 17:27

You're missing a ^:

urlpatterns = patterns('',
    url(r'^$', 'mysite.views.home', name='home'),
    url(r'^books.html/$', 'azahra.views.bookpage', name='books'),
    url(r'^index.html/$', 'azahra.views.home', name='home'),
)

Take a look at the url template tag - it'll simplify your URL routing in your templates and move you away from these types of errors.
