Re: Generic views and url issues

Have you tried it without the quotes around 'detail' in the url template tag invocation?

If I'm remembering correctly, the need for the quotes depends on django version and options.

Thanks for your response!

Unfortunately, your suggestion did not eliminate the NoReverseMatch error.

NoReverseMatch at /testadcall/

Reverse for 'detail' with arguments '()' and keyword arguments '{'object_id': 1}' not found.

I have another example where I request the list view, which does not expect arguments, to keep it even simpler.

urls.py

queryset = {'queryset': Adcall.objects.order_by('name')}

urlpatterns = patterns('django.views.generic.list_detail',

    url(r'^$','object_list', queryset, name="adcalls"),

    url(r'^(?P<object_id>\d+)/detail/$', 'object_detail', queryset, name="detail"),

)

template:

EDIT TEMPLATE

{% load url from future %}

<form action="" method="post">{% csrf_token %}

{{ form.as_p }}

<input type="submit" value="Submit" />

</form>

<a href="{% url 'adcalls' %}">Back to adcall list</a>

Error:

NoReverseMatch at /testadcall/1/detail/

  Reverse for 'adcalls' with arguments '()' and keyword arguments '{}' not found.

I've been trying to understand how to use generic views.  I've followed some tutorials, and read through Django docs, but I can't get the url function to work in my templates.

I get the error
NoReverseMatch at /testadcall/
Reverse for 'detail' with arguments '(1,)' and keyword arguments '{}' not found.

in my urls.py

queryset = {'queryset': Adcall.objects.order_by('name')}

urlpatterns = patterns('django.views.generic.list_detail',
    url(r'^$','object_list', queryset, name="adcalls"),
    url(r'(?P<object_id>\d+)/detail/$', 'object_detail', queryset, name="detail"),
)

in my template for the list view:

{% load url from future %}
{% if object_list %}
    <ul>
    {% for adcall in object_list %}
        <li><a href="{% url 'detail' adcall.id %}/">{{ adcall.name }}</a></li>
    {% endfor %}
    </ul>
{% endif %}

I've tried no quotes, single quotes, and double quotes around the url name "detail", with no apparent effect.

Am I wrong in thinking that this should work?

The problem is a mismatch between your urls.py pattern and the parameters you give to the url templatetag - note in the error message that it mentions both arguments and keyword arguments (with your example having a single non-keyword argument). However, in your url pattern for the "detail" url, you use a named capture (object_id). In this case, you must use a keyword argument to match:

{% url 'detail' object_id=adcall.id %}

Michael.
