Re: UnboundLocalError

Also, you're missing 'else' statement, so if elemCategory is neither 'routing' nor 'switching', testElement will never be defined.
You should either assign default value to testElement before if-else block or add 'else' statement, like so:

testElement = ApprovedTestElement.objects.filter(testElemType=elemType)  # note that .filter() returnes QuerySet, not a single object
if ... :
    ...
elif ... :
    ...

return render(..., {'testElement': testElement})


or


if ... :
    ...
elif ... :
    ...
else:
    testElement = ApprovedTestElement.objects.filter(testElemType=elemType)

return render(..., {'testElement': testElement})

Hi!

That's about Python. You can't use variable if it wasn't defined earlier.
In your code return statement should have one less indentation level:

...
if(elemCategory=='routing'):
    testElement = ApprovedTestElement.objects.filter(testElemType=elemType,routing='Y');
elif(elemCategory=='switching'):
    testElement = ApprovedTestElement.objects.filter(testElemType=elemType,switching='Y');
 
return render(request,self.template_name,{'testElement':testElement,'testPlanId':testPlanId})


Also, you should definitely read PEP-8 - https://www.python.org/dev/peps/pep-0008/.

Hi Everyone, 

Class FilterSearch(View):
    template_name = 'approved/approvedElementsSEView.html

    def post(self, request, testPlanId):
        elemType = request.POST.get('testElementType);
        elemCategory = request.POST.get('category');
        
        if(elemCategory=='routing'):

            testElement = ApprovedTestElement.objects.filter(testElemType=elemType,routing='Y');

        elif(elemCategory=='switching'):

            testElement = ApprovedTestElement.objects.filter(testElemType=elemType,switching='Y');
         
            return render(request,self.template_name,{'testElement':testElement,'testPlanId':testPlanId})

I am trying to send a different testElement based on which if condition has been satisfied. I am new to Django and I keep getting UnboundLocalError Exception : local variable 'testElement' referenced before assignment . I have tried defining testElement outside the if loop, but maybe that's not the right way! Any Help will be greatly appreciated!
