User object has no attribute-CodePudding

I am creating an app in which it manages ranking and ELO functions for a local hobby game store. I am using django to write the application. I am having troubles trying to figure out how to access a user's model from their name.

models.py

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    mtg_currentELO = models.IntegerField(default=1000)
    mtg_highestELO = models.IntegerField(default=1000)
    mtg_lowestELO = models.IntegerField(default=1000)

   def __str__(self):
        return self.user.username

views.py

def home(request):
    users = User.objects.all()
    
    if request.method == 'GET':

        user1 = User.objects.get(username=request.POST['player1']) 
        user2 = User.objects.get(username=request.POST['player2'])
        print(user1, user2) # DEBUG LINE -- it does find
        print(user1.mtg_currentELO) # DEBUG LINE -- it does NOT FIND

So what I'm trying to accomplish is the find mtg_currentELO from the user1. However, I can't access it via user1.mtg_currentELO. How can I access the property mtg_currentELO of a Profile, via the user's name?

CodePudding user response：

You should assign a related name to OneToOneField like this:

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, related_name="assigned_profile")
    ...

then you will be able to access it like user1.assigned_profile.mtg_currentELO
