I have some very simple views that act as forms because there is no
information to fill out. I get all the information from the url and
the request object.
For example, I may have a model like:
class Subscription(models.Model):
user = models.ForeignKey(User)
magazine = models.ForeignKey(Magazine)
So I have URL's like
r'^subscriptions/subscribe/(?P<magazine_id>[\w-]+)/$'
r'^subscriptions/unsubscribe/(?P<magazine_id>[\w-]+)/$'
My views are like...
@login_required
def subscribe(request, magazine_id):
# get relevant objects
magazine = get_object_or_404(Magazine, id=magazine_id)
# retrieve subscription or create if it doesn't exist
try:
subscription = Subscription.objects.get(user=request.user,
magazine=magazine)
message = 'You are already subscribed'
except Subscription.DoesNotExist:
subscription = Subscription(user=request.user,
magazine=magazine)
subscription.save()
message = 'You are now subscribed.'
return render_to_response(
'myapp/subscribed.html',
{'subscription': subscription, 'message': message},
context_instance=RequestContext(request)
)
Okay, now finally the questions...
How can I implement an intermediate step in this process where I have
a confirmation message and an accept / cancel button?
Could a generic decorator be made to add an intermediate message.
Like ...
@disclaimer("Are you over the age of 18?")
def my_dirty_view(request):
return SomethingDirty()
Is it bad to have a view without a form actually do stuff like
database inserts and deletes via GET rather than POST?
I have several objects similar to this example of Subscription each of
which would have their own disclaimer / warning upon creation /
deletion.
I need some suggestions.
Thanks,
