How can you use the @cache_page decorator with Django class based views?

[daniels]

The only method that seems to be working is adding the decorator in urls.py 
which is ugly.

Is there any way to apply this decorator in the view?

class HomeView(View):
@method_decorator(cache_page(60 * 60))
def dispatch(self, *args, **kwargs):
return super(HomeView, self).dispatch(*args, **kwargs)

I've tried the above but it doesn't seem to be working. I've also tried 
adding it to the get method (which is what I want to cache).

I'm using FileBasedCache and only when I use cache_page decorator in 
urls.py I see files being created in my cache folder. With the method above 
nothing happens.

Existing database - new project

[Robert Daniels]

I understand it is possible to use an existing database on a new Django 
project. 

As I see it, I have 2 choices.

1 - Use the existing database and deal with it in that fashion.

or

2 - Create a new project to store the same type of data as if there were no 
existing database, Then write a separate export-import script to move the 
data from the existing db to the new structure. 

Wondering if anyone has gone through the "good" and "bad" of each of these. 
I have about 100,000 records in the database, but moving the data across 
should not be that difficult as its a pretty flat model

Re: Django dev server issue

[daniels]

Ok, so i used pdb and did a line by line pass, but i didn't get anything.
All data seems to be normal. I even edited socket.py and did a print on data
to see what's going on and everything seems normal.. :( so i'm left with no 
idea
I guess i'll have to get used with this hangs.

Just tried latest version of Django 1.2.4 and same issue
I'll try that. Never used pdb before so let's see how things will go.
I'll reply with updates.

Re: Django dev server issue

[daniels]

Hi,
Unfortunately i did not found the case, and i'm getting it pretty
often, about 3 out of 5 times i refresh the page.
If i leave it loading and i don't stop it it stays like that for about
30-40 seconds and then the page loads.
I just don't understand what is causing this.
I've restarted the server like 10 time or more from the first time i
got this and i'm still getting it every time i run it.

My Python version is : ActivePython 2.6.6.17 (ActiveState Software
Inc.) based on
Python 2.6.6 (r266:84292, Nov 24 2010, 09:16:51) [MSC v.1500 32 bit
(Intel)] on
win32

and Django: (1, 2, 3, 'final', 0)

I did a lot of dev on Windows 7 before but i never had this issue. So
my thoughts are that this is either
related to this Django version or Python version.

Django dev server issue

[daniels]

Hi,
I'm having a issue with Django's dev server. I did a "django-admin.py
startproject" then "manage.py startapp home", then added the app in
settings.py and in urls.py. The app only has  a index function in
views.py which is mapped to / and just renders a simple html template.
What happens is that sometimes(and this is often) when i load the page
in a broswer (tryed Chrome and Firefox) or refresh it, the page starts
loading but it never finishes. And if i hit the browser's stop button
i get this in the console



Exception happened during processing of request from ('127.0.0.1',
52495)
Traceback (most recent call last):
  File "C:\Python26\lib\SocketServer.py", line 283, in

self._sock.sendall(buffer(data, write_offset, buffer_size))
error: [Errno 10053] An established connection was aborted by the
software in your host machine



Any idea what's causing this? As it really cripples my dev time.
I'm on a Windows 7 32bit machine

Re: temp url with time limit

Take a look at this Lighttpd module:

You could implement something based on what the module above is doing.
