Question

I have a Django app, which populates content from a text file, and populates them using the initial option in a standard form. The file gets updated on the server, but when the form gets refreshed, it picks up content from the a previously saved version, or the version before the Apache WebServer was reloaded.

This means that the file is getting cached, and the content is picked up from a wrong cache and not the new file.

Here is my code. How do I ensure that everytime, spamsource function picks up the content from the most recently saved file, instead of from a cache.

def spamsource():
   try:
    f= open('center_access', 'r')
    read=f.read()
    # some manipulation on read 
    f.close()
    return read
   except IOError:
    return "prono.nr"

class SpamForm(forms.Form):

    domains =forms.CharField(widget=forms.Textarea(attrs=attrs_dict),
                                label=_(u'Domains to be Banned'), initial= spamsource())
def function(request):
    # It writes the file center_access based on the changes in the textbox domains

I fixed this. The problem was the presence of all the caching middleware in settings.py, which were being used to speed up another side of the web app.
