Help with implementing dynamic views/models
This may seem like a very simple question and I have just missed the
answer in the piles of documentation and tutorials that I've read over
the past two days. I'm new to Django and trying to implement an
internal site at work, and I'm the only Python/Django person we have,
so this is all on me.
What I am doing is this: I have a set of .html files, templates, which
are named testn.html (i.e. test1.html, test2.html, etc) Each template
extends base.html, but they each have at least 2 divs that I need to
populate with HTML that is entered in the admin interface and stored
in the Page model. What I need to do is this:
from the url parse what test is being requested:
url(r'^test(\d{1})/$', test),
cal the test view:
def test(request, testn):
try:
testn = str(testn)
return direct_to_template(request, template="test%s.html" %
testn)
except ValueError:
raise Http404()
And then return the template, but with the correct object attached to
it, filtered by name. I can't find a way to do this, all that I can
find are ways that make me grab all the objects (and where do I do
this? In models.py or views.py? There are conflicting thoughts on
this). I really just need to grab the one object, and if it has the
fields I need, to populate the template with them. Is there an easy
way to do this that won't require me to loop over all objects?
Thank you so much for any help or insight!

Re: Help with implementing dynamic views/models
That is exactly what I want to do, I can't seem to understand exactly
how to implement that and have it populate in the template. Do I just
define the variable in the views and then in the template use
{{ variable_name }} where I need it? Because I tried that first and it
didn't work. So, maybe I'm just not sure what it is I'm doing
exactly ;)
Thanks for any help!

Re: Help with implementing dynamic views/models
I thank you for your help and apologize for my naivete, however I
still am not seeing that tag populate in the template. Here is my view
function in its entirety:
def test(request, testn):
try:
testn = str(testn)
page = Page.objects.filter(name = "test%s" % testn)
return direct_to_template(request, template="test%s.html" %
testn, extra_context={page:page})
except ValueError:
raise Http404()
I am using {page:page} because anything else returns errors in debug
mode.
in my template I have :
{{ page.leaderboard }}
the page object looks like this:
class Page(models.Model):
name = models.CharField(max_length=25, verbose_name='Page Name')
leaderboard = models.TextField(max_length=500, null=True,
blank=True, verbo\
se_name='Leaderboard Tag')
rectangle = models.TextField(max_length=500, null=True,
blank=True, verbose\
_name='300x250 Tag')
rectangle2 = models.TextField(max_length=500, null=True,
blank=True, verbos\
e_name='Additional 300x250')
def __unicode__(self):
return self.name
I know that once I figure this out, I'm going to feel rather daft and
I appreciate all the help you've given me! Thanks so much!
