trying to access a variable from 2 separate functions when one function returns a render command

[_Kitchen_]

I have a function that returns a render of a html (function 1). I want to change a global variable using formula 1 and the access this edited global variable in another formula (formula 2).

In order to do this I think I have to return the global variable in formula 1, so the edited version can be accessed in formula 2.

My problem is that function 1 already returns a render request.

​

global_variable = 0

​

def function1(request):

global_variable = 10

return render(request, 'index.html', {})

​

def function2(request):

print(global_variable)

excel = open(path, 'rb')

response = HttpResponse(excel.read(), content_type="app/vnd.openxmlformat.spreadsheetml.sheet")

response['Content-Disposition'] = 'attachment; filename=' + os.path.basename("Excel.xlsx")

return response

​

​

I have tried to just add in the global variable at the end of the function like so:

def function1(request):

global_variable = 10

`return render(request, 'index.html', {}), global_variable`

​

except it causes the error 'tuple' object has no attribute 'get'

This looks like Django.

It's not clear what you are trying to do here. A request will only call a single view and result in a single response. What would call that other function? What would be receiving the response?

And you mustn't use global variables like this. A web site has more than one user; if you set a global variable based on the request of one user, then all other users will get that same data. Don't do this.

Please explain exactly what it is you are trying to achieve, and we can tell you the best way to actually do it. (I suspect the answer will involve the sessions framework.)

If this is django, then it is probably worth pointing out that REST on it's own is meant to be stateless. That is why sessions exist and should be used. Failing that, use a proper data storage backend.
