Re: trying to understand get_absolute_url, NoReverseMatch and url configs
Some followup, in case some other poor soul searches for this topic:
I found some better doc for get-absolute-url() here:
http://docs.djangoproject.com/en/dev/ref/models/instances/?from=olddocs#get-absolute-url
Including a better example:
@models.permalink
def get_absolute_url(self):
return ('archive_view', (), {
'year': self.created.year,
'month': self.created.month,
'day': self.created.day})
So I changed my method like this:
@models.permalink
def get_absolute_url(self):
return ('organization', (), {
"type_slug": self.type.slug,
"org_slug": self.slug})
...which works!
However, the permalink decorator still doesn't work. Get error:
AttributeError: 'Org' object has no attribute 'permalink'

Re: trying to understand get_absolute_url, NoReverseMatch and url configs
Got the url tag version working this way:
Changed the url pattern to:
url(r'^org/(?P[-\w]+)/(?P[-\w]+)/$',
'orgs.views.org', name='organization'),
And the template to:
{% url organization type_slug=org.type.slug, org_slug=org.slug %}
And added the new keyword to the view.
But I'm still a long ways from understanding this stuff enuf to do a
new one with any confidence.

Re: trying to understand get_absolute_url, NoReverseMatch and url configs
Tried going about this another way:
In the template:
{% url orgs.views.org org.type.slug, org_slug=org.slug %}
That gets me this error message:
Don't mix *args and **kwargs in call to reverse()!
But how is that different from this example in the Django doc?
http://docs.djangoproject.com/en/dev/ref/templates/builtins/#url
{% url path.to.some_view arg1,arg2,name1=value1 %}
"The first argument is a path to a view function in the format
package.package.module.function. Additional arguments are optional and
should be comma-separated values that will be used as positional and
keyword arguments in the URL. All arguments required by the URLconf
should be present."

Re: trying to understand get_absolute_url, NoReverseMatch and url configs
Shabda,
Thanks for trying, but:
> return ('orgs.views.org', [self.type.slug, self.slug])
In the shell, that gets me:
TypeError: reverse() argument after ** must be a dictionary
But do I understand correctly that the first argument shd be a view?
And that what gets returned from get_absolute_url goes into reverse()?
Looking at the code for urlresolvers.revers() now. If I read
correctly, it wants either a view or an URL pattern name.
That's a start at getting more understanding.

Re: trying to understand get_absolute_url, NoReverseMatch and url configs
You want something like this
@models.permalink
def get_absolute_url(self):
return ('orgs.views.org', [self.type.slug, self.slug])
Essentially, you code would be doing something like reverse('/org/
hoa/', kwargs={..}) which fails. Templates supress Exceptions so you
do not see them.

trying to understand get_absolute_url, NoReverseMatch and url configs
Altho I have read alot of the relevant documentation, and searched
this group and the Web, I remain confused about these topics and their
relationships. Something is not sticking in my brain.
I usually get something working by blind cut and paste. Looking for a
more conceptual explanation, or even some pointers to where to look
next.
Here's my current problem:
in models.py:
def get_absolute_url(self):
prefix = "/org/%s/" % self.type.slug
return (prefix, None, {"org_slug": iri_to_uri(self.slug)})
in urls.py:
url(r'^org/(\w)+/(?P[-\w]+)/$', 'orgs.views.org',
name='org'),
in a template:
{{ org.get_absolute_url }}
returns nothing. No error message.
Error message from the shell:
>>>org,get_absolute_url()
[...]
NoReverseMatch: Reverse for '/org/hoa/' with arguments '()' and
keyword arguments '{'org_slug': 'cp'}' not found.
If I enter the url http://127.0.0.1:8000/org/hoa/cp/ in the address
bar, it works fine.
Using current trunk and the Django dev server.
What am I missing?
