Question

In a Django app, I have an extra module. So my app is called header and inside it I have a model, view and a header file. Inside of the header file I have a class called resources which does what I want, but for some reason on a page refresh, it duplicates the information.

view:

def home(request):
header = Resources("home") #generate the resources for this page

return render_to_response('pages/index.html', {'header': header, 'content': test})

resources:

class Resources(object):

javascript_resources = []
javascript_files = []
style_sheets = []

def __init__(self, page_id = "home"):
    self.page_id = page_id.lower()
    self.get_status()
    self.get_meta()
    self.get_javascript()
    self.get_style_sheets()

def get_status(self):

def get_meta(self):

def get_javascript(self):

def get_style_sheets(self):

So what happens is, the header.javascript_resources list should only be 3 members long, but each duplicate it adds to it. So for some reason this object is staying in memory, even after a page refresh. What is causing this?

Answer 1

The problem seems to be that you created javascript_resources as class variable. Try to move its initialisation in the __init__ method.
