Question

I'm pretty new to web development (not to programming), but I just successfully (sort of) deployed a really basic hello-world style Django app. The first time I did it, I had an issue in my HTML. Here's my whole view with the error:

from django.http import HttpResponse
import datetime

def homepage(request):
  now=datetime.datetime.now()
  html="<html><body><It is now %s.</body></html>" % now
  return HttpResponse(html)

The extra < just after the first body tag caused the browser to display a blank page. I figured out what I did and fixed the error. I also added a title so I'd be able to track what's going on (somewhat) better. The old view became this:

from django.http import HttpResponse
import datetime

def homepage(request):
  now=datetime.datetime.now()
  html="<html><head><title>Hello</title></head><body>It is now %s.</body></html>" % now
  return HttpResponse(html)

Now the browser displays the old view (a blank page) most of the time, just the title with a blank body sometimes, and occasionally the whole correct new view. I have no clue what's going on. I'm running nginx with flup to handle the FastCGI. Ideas?

Solution

After changing your code you need to restart your FastCGI server, not Nginx.
