Hi,
The homepage of my app displays a list of items with their content
(might as well think of it as a blog), and you can also link to
individual items. I'd like to use the same set of templates for both
cases.
So my handlers look something like this:
-----------------------------------------------------
class MainPage(webapp.RequestHandler):
def get(self):
items = db.GqlQuery('SELECT * FROM Item')
values = {'items': items}
self.response.out.write(template.render('main.html', values))
class SingleItem(webapp.RequestHandler):
def get(self):
key = #determine item key
linked_item = db.get(key)
values = {'linked_item': linked_item}
self.response.out.write(template.render('main.html', values))
-----------------------------------------------------
And here's main.html:
-----------------------------------------------------
{% if linked_item %}
{{ linked_item.content }}
{% else %}
{% for item in items %}
{{ item.content }}
{% endfor %}
{% endif %}
-----------------------------------------------------
This doesn't look like a great solution but I haven't been able to
think of (or find) a better one. I've been told to use db.get when
possible because it's faster, but the object it returns isn't iterable
and so the template becomes awkward.
Is there a way to put the return from db.get into an iterable object?
That way I could simply have "{% for item in items %}
{{ item.content }} {% endfor %}" in my template and it would work
without errors.
Should I just use a query instead of db.get? Any other solutions? I've
been looking through GAE and Django template docs but haven't found
anything yet.
Any ideas, even a link to the right piece of documentation would be
awesome.
Thanks,
Kev
