Django Rest Framework custom error messages
I am trying to add custom field error messages for SlugRelated field as follows:
class Test(serializers.ModelSerializers):
team = serializers.SlugRelatedField(queryset=Team.objects.all(), slug_field='name',
error_messages={"does_not_exist": "Team not found"})
Works as expected. My query is how do I pass the team name dynamically in the error message. I tried the following but it did not work:
class Test(serializers.ModelSerializers):
team = serializers.SlugRelatedField(queryset=Team.objects.all(), slug_field='name',
error_messages={"does_not_exist": f"Team {team} not found"})
python django django-rest-framework

The default error message for does_not_exist
take slug_name
& value
as the keyword argument to format the error string.
Solution is to replace team
with value
.
Solution:
class Test(serializers.ModelSerializers):
team = serializers.SlugRelatedField(
queryset=Team.objects.all(),
slug_field='name',
error_messages={"does_not_exist": "Team {value} not found"}
)
Ref: relations:SlugRelatedField Source Code
That does not work...it gives an error saying value not defined..
