Re: Generic views and url issues

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.
