This is an example of a structure, also shows how to use the
get_absolute_url method. Note that the first parameter that is passed to
the same method (city_detail) is the name assigned to the url in
urlpatterns, and that the third parameter is a list in which is slug, which
matches the expected parameter in the urlpattern, and also expected by the
view. Note also that the view specifies the template to be used.
# in the models.py file
class City(Displayable):
# fields, class Meta, etc.
@models.permalink
def get_absolute_url(self):
return ("city_detail", (), {"slug": self.slug})
# in the views.py file
def city_detail(request, slug, template="cities/city_detail.html",
extra_context=None):
"""
Custom templates are checked for using the name
``cities/city_detail_XXX.html`` where ``XXX`` is the city slug.
"""
city = get_object_or_404(City, slug=slug, status=2)
context = {"city": city,
"editable_obj": city}
context.update(extra_context or {})
templates = [u"cities/city_detail_%s.html" % str(slug), template]
return TemplateResponse(request, templates, context)
# in the urls.py file
urlpatterns = [
url("^(?P<slug>.*)%s$" % _slash, city_detail, name="city_detail"),
]
# in the templates/cities/city_detail.html file
{% extends "base.html" %}
{% load mezzanine_tags keyword_tags %}
{% block meta_title %}{{ city.meta_title }}{% endblock %}
{% block meta_keywords %}
{% metablock %}
{% keywords_for city as tags %}
{% for tag in tags %}{% if not forloop.first %}, {% endif %}{{ tag
}}{% endfor %}
{% endmetablock %}
{% endblock %}
{% block meta_description %}
{% metablock %}{{ city.description }}{% endmetablock %}
{% endblock %}
{% block title %}
{{ city.title }}
{% endblock %}
{% block breadcrumb_menu %}
{{ block.super }}
<li class="active">{{ city.title }}</li>
