Optional get parameters in django?

Question

Can someone please explain how you can write a url pattern and view that allows optional parameters? I\'ve done this successfully, but I always break the url template tag.

Answer 1

For anyone who is still having this problem. I use Django 1.5 (updated: using 1.8) and it's still working fine.

I use:

urls.py

url(r'^(?P<app_id>\d+)/start/+(?P<server_id>\d+)?', views.restart, name='restart')

Then when I want to have the two urls

/1/start/2

and

/1/start

I use:

{% url '<namespace>:start' app.id %}
{% url '<namespace>:start' app.id server.id %}

This will create the urls

/1/start/2 and 
/1/start/ <- notice the slash.

If you create a url manually you have to keep the / in mind.

I hoop this helps anyone!
