KeyError: 'f'

I fixed the error by adding a , next to true like this :

class Relationship(Model):
    from_user=ForeignKeyField(User, related_name='relationships')
    to_user=ForeignKeyField(User, related_name='related_to')
    class Meta:
        database=DATABASE
        indexes=((('from_user','to_user'),True),)

class Liketable(Model):
    from_user=ForeignKeyField(User, related_name='relationships')
    to_user=ForeignKeyField(User, related_name='related_to')
    class Meta:
        database=DATABASE
        indexes=((('from_user','to_user'),True),) # <- , next to parenthesis in
