'Bypassing NoneType in a list comprehension
To work around when there is no value x.competition.name, I tried to use is not None:
'competition': [x.competition.name if x.competition.name is not None else '-' for x in a]
But the error still keeps showing up:
AttributeError: 'NoneType' object has no attribute 'name'
How can I go about getting around this problem?
Solution 1:[1]
Apparently competition is None, so please replace
[x.competition.name if x.competition.name is not None else '-' for x in a]
using
[x.competition.name if x.competition is not None else '-' for x in a]
Solution 2:[2]
The error message is saying that you tried to get None.name. That means x.competition must be None, which is why you can't get a name attribute from it. Instead, try making your condition x.competition is not None.
