suggestion about {% url %}
!张沈鹏(电子科大 08年毕业)
Example
mytags.py:
.....
@register.inclusion_tag('xxx.html')
def page_link(url_name):
return {"url_name":url_name}
______________________________________________________
xxx.html:
<a href="{% url url_name 1 %}">1</a>
______________________________________________________
Here , I modify the code of URLNode to do this :
class URLNode(Node):
def __init__(self, view_name, args, kwargs):
self.view_name = view_name
self.args = args
self.kwargs = kwargs
def render(self, context):
from django.core.urlresolvers import reverse, NoReverseMatch
args = [arg.resolve(context) for arg in self.args]
kwargs = dict([(smart_str(k,'ascii'), v.resolve(context)) for
k, v in self.kwargs.items()])
def _reverse(url_name):
return reverse(url_name,args=args, kwargs=kwargs)
try:
return _reverse(self.view_name)
except NoReverseMatch:
try:
project_name = settings.SETTINGS_MODULE.split('.')[0]
return _reverse(project_name + '.' + self.view_name)
except NoReverseMatch:
url = context.get(self.view_name,'')
if url:
try:
return _reverse(url)
except NoReverseMatch:
try:
return _reverse(project_name + '.' + url)
except NoReverseMatch:
return ''
return ''

that why I think below code is useful
mytags.py:
.....
@register.inclusion_tag('xxx.html')
def page_link(url_name):
return {"url_name":url_name}
______________________________________________________
xxx.html:
<a href="{% url url_name 1 %}">1</a>

If you're going to post things like this could you please explain what
the difference is? I've stared at this for more than a couple of minutes
both times you posted and I really have no idea what you are trying to
achieve. I'm not about to reverse-engineer dozens of lines of code in
your URLNode rewrite to work out what might be different from the
current stuff.
If you are trying to propose a new feature, explain what it does. And
how it remains backwards compatible with the existing code and why it
cannot be done with a third-party tag (which would mean why is it so
commonly used that we cannot live without it?). Otherwise you are not
helping yourself or helping us to help you.
Thanks,
Malcolm

patterns , it will try to find context[urlname] in patterns.

Aah ... so an attempt to allow variables in the URL tag. Okay. Now I
understand what you're trying to do.
This (variables in the URL tag) hasn't gathered a lot of support in the
past when it's been suggested -- there are always some supporters for
any idea, but it wasn't exactly critical mass. We got a bit stuck in
syntax discussions, too, if you look back at the old threads about this.
Transparently promoting something from a string to a variable is not
very uniform with the way template tags work (although I'll argue that
the syntax of the url tag isn't particularly uniform in the first
place).
Still, it's something to think about. You might get more feedback now
that your goal is clearer. Personally, I preferred the approach in
#3769, which was more explicit, but it didn't get enough support.
Regards,
Malcolm

Because my english very very poor :) , so I alway try to read and
write as little as I can .
Thanks for you pay attention to read my posting and reply it . You are
a good man .
I think passing a variable to url is useful when you are writing a
inclusion_tag.
for example a inclusion_tag:
{% page_link "bbs_posting_list" 25 221 %}
@register.inclusion_tag('xxx.html')
def page_link(url_name):
return {"url_name":url_name}
with a template like:
<a href="{% url urlname %}">xxx</a>
can generate links as below:
Prev 1 ... 23 24 25 26 27 ...221 Next
if variable can't work on with {%url%} , you have to do more work to
implement this .
