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})
