Re: Official Django tutorial 3: Reverse for 'detail' with arguments '('',)' and keyword arguments '{}' not found.

thanks Xavier,

the problem was that I mistyped poll.id as poll_id and now it works fine.

Thanks again for your input.

Regards,

Max

Hi,

It looks like you are missing the poll in your context.

{% url 'detail' poll.id %} will try to match an url named detail with the argument poll.id

However Django says it can't find a reverse for 'detail' with arguments ('',) which means that you don't have a poll in your context (or the poll.id is empty).

Double check that you already did the part https://docs.djangoproject.com/en/1.5/intro/tutorial03/#raising-a-404-error since the view is there and that there's no typo in the render(..., {'poll': poll})

Hi everyone,

I'm following the official django tutorials to learn Django by building the polls app...

Everything seemed great until chapter 3.

I had this link as part of my index template, which was working fine:

<li><a href="/polls/{{ poll.id }}/">{{ poll.question }}</a></li>

however, this is hardcoded and the tutorial suggested a better way was to use:

<li><a href="{% url 'detail' poll.id %}">{{ poll.question }}</a></li>

so that you'll be better of when dealing with huge number of templates and u have to make changes to the url.

Since I made the above change I get the following errors when I run the app:

Exception Type:	NoReverseMatch
Exception Value:	Reverse for 'detail' with arguments '('',)' and keyword arguments '{}' not found.

Usually I could easily read where the error is coming from and deal with it but in this case I can't spot the cause of the error hence I'm unable to progress with my study.

Any help will be greatly appreciated.
