Cannot delete element from django arrayfield

I am trying to delete an element from an arrayfield in notes model 

obj=notes.objects.get(id=n_id,related_to__contains=[c_id])
obj.related_to.remove(c_id)
obj.save()

where related to is the arrayfield

related_to=ArrayField(models.IntegerField())

n_id is the note's id and c_id is contact's id. When i try to do this i am getting the error ValueError: list.remove(x): x not in list . I've checked and the c_id is in the arrayfield. What is wrong?

Since it finds the object, c_id is definitely in related_to field. I believe you are getting this error because c_id is not an int type but string type. You should first convert it to int:

c_id = int(c_id)
obj=notes.objects.get(id=n_id,related_to__contains=[c_id])
....
