Here is the situation
I have a model like
class Content(ndb.Model):
likeCount=ndb.IntegerProperty(default=0)
likeUser = ndb.KeyProperty(kind=User, repeated=True)
When a new content generate than a new "Content" object is generated like
content_obj = Content(parent=objContentData.key, #Where ContentData is
another ndb.Model subclass
likeUser=[],
likeCount=0
)
And when any user like the same content than below function gets called
def modify_like(contentData_key, user_key):
like_obj = Content.query(parent=contetData_key).get()
if like_obj:
like_obj.likeUser.append(user_key)
like_obj.likeCount += 1
like_obj.put()
###################Problem#############
Now the problem is that when at the same time more than 4 user like the
same content than this object write wrong data.
So how can I solve this problem
