You can filter the Tasks to return Tasks with the user as like through an F object ^[Django-doc] to refer to a field, so:

from django.db.models import F

Task.objects.filter(
    likes__user_info=F('user_info')
)

or for a Task, you can check in a Task with:

def has_self_like(self):
    return self.user_info_id in self.likes.values_list('user_info_id', flat=True)

or through an exists():

def has_self_like(self):
    return self.likes.filter(user_info_id=self.user_info_id).exists()

Note: Normally one does not add a suffix _id to a ForeignKey field, since Django will automatically add a "twin" field with an _id suffix. Therefore it should be task_id, instead of task.
