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})
