How to run two methods inside django models in parallel manner? - django

Question

I'm incrementing two different fields in User models which are the number of likes given to user's post and number of likes received by the user's post. I did this through adding two methods in class model. It is working when I'm liking other posts but however, if I liked my own post it is not working. Anyone know how to solve this problem?
Code snippet for user models
class User(models.Model):
username = models.CharField(max_length=100)
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
email = models.EmailField(null=True)
company = models.ForeignKey(Company, on_delete=models.CASCADE)
datetime_joined = models.DateTimeField(auto_now_add=True)
num_likes_received = models.IntegerField(default=0)
num_dislikes_received = models.IntegerField(default=0)
num_likes_given = models.IntegerField(default=0)
num_dislikes_given = models.IntegerField(default=0)
total_votes = models.IntegerField(default=0)
prediction = models.BooleanField(default=True)
def add_total_votes(self, vote):
self.total_votes += vote
self.save()
def inc_num_likes_received(self):
self.num_likes_received += 1
print("1 like received")
self.save()
def inc_num_likes_given(self):
self.num_likes_given += 1
print("1 like given")
self.save()
Code snippet for Post Model
class Post(models.Model):
post = models.TextField()
num_likes = models.IntegerField(default=0)
num_dislikes = models.IntegerField(default=0)
username = models.ForeignKey(User, on_delete=models.CASCADE)
datetime_comments = models.DateTimeField(auto_now_add=True)
def add_num_likes(self):
self.num_likes+=1
self.save()
def __str__(self):
return str(self.id)
Function for submitting like to certain post and at the same time this is where I executed the created two method from the models. (inc_num_likes_received and inc_num_likes_given)
def submit_like(request):
User_PK = User.objects.get(username=request.user)
User_Give_Like = get_object_or_404(User, pk=User_PK.id)
pk = request.POST.get('Status', None)
post = get_object_or_404(Post, pk=pk)
post.add_num_likes()
User_PK_Receive = User.objects.get(id=post.username.id)
User_Receive_Like = get_object_or_404(User, pk=User_PK_Receive.id)
LikeObject = Likes(username = User_Give_Like, post = post, liked=True, disliked=False)
LikeObject.save()
User_Give_Like.inc_num_likes_given()
User_Receive_Like.inc_num_likes_received()
return HttpResponse(200)
To become more specific these two lines of code below are the methods. The problem here is that the first line of code are not actually working but the last line are the only working. Whenever I rearranged these two lines of code the only executed was the last line of code.
....
User_Give_Like.inc_num_likes_given()
User_Receive_Like.inc_num_likes_received()
Example:
In this case, User_Receive_Like.inc_num_likes_given() are working but User_Receive_Like.inc_num_likes_received() are not working and vice-versa.
....
User_Receive_Like.inc_num_likes_received()
User_Give_Like.inc_num_likes_given()
The expected output is both fields num_likes_given and num_likes_received must incremented by 1.
