get_absolute_url and project name path

[Donn]

Hi,
I am looking at writing a tag that will deliver my project 'name' (directory
name) so that I can get around problems.

1. At the moment, my site is on a URL like http://blah/hdl/....

2. /hdl/search/ displays result. They include a link to the flatpage that
matched:
<a href="{{ page.get_absolute_url }}">

3. This produces HTML like: <a href="/about/">

4. But, the link to the actual page is either
<a href="about/"> or <a href="/hdl/about/">

5. So, I want to preface that with something like:
<a href="{% projectname %}{{ page.get_absolute_url }}">

Is this sensible, or is there some already done method? I suspect I can
override the get_absolute_url method somehow...

If <a href="about/"> works for you then it's the same as <a href="./
about/">.

So, all you need is this:

<a href=".{{ page.get_absolute_url }}">

Unfortunately this only works at root directory level. It will fail if
the page is several levels down the URL hierarchy. For example, if that
code appeared in two different pages with URLs

http://server/thing

and

http://server/dir/thing

in the first page it would reference http://server/about but in the
second it would reference http://server/dir/about.

Right...it only solves the problem if the case that the OP mentions
above is the only level at which he needs this to work.

Cunning. As mentioned it has problems if it's deeper down, but it's really
elegant.

Is this not a recurring theme in Django? I mean links and whatnot are stock in
trade for web apps and getting around seems to be quite hard if you want to
keep DRY and plugable.

Not at all. When you write your own models, you get to define your own
get_absolute_url() on it that should use absolute paths. Similarly all
URLs defined in your own urls.py files may be referenced elegantly
with the {% url %} tag[1] or the the URL reverse API[2]. That let's
you stay DRY.

Your problem above arises from the fact that you are using a contrib
app that doesn't have a good way of letting you override the flatpage
instance's url field representation with your own pattern because the
flatpage.url field is intended to represent an absolute URL path (/hdl/
about/ in your case instead of /about/).

Okay, I was just surprised because surely web sites that use flatpages need to
link between them. Perhaps this is a case for a feature request.

Thanks for the input on this.
