[Answered ]-Django ManyToManyField reverse Relationship

✅

Since you set up a many-to-many relationship, a Ticket may have many User_Detail objects. Therefore, Ticket.user_detail_set is a manager, not a single object. You could get the first user associated with a Ticket like this:

ticket.user_detail_set.first().user.username

But it sounds like you actually want a one-to-many relationship between Ticket and User_Detail, meaning you actually want Ticket to have a foreign key relationship. Your models should probably look like this:

class User_Detail(models.Model):
    user = models.OneToOneField(User)

class Ticket(models.Model):
    user = models.ForeignKey(User)
    title = models.CharField(max_length=100)
    contents = models.TextField()

Then you can do:

ticket = Ticket.objects.get(pk=1)
user = ticket.user

You might even be able to drop the User_Detail model entirely, unless you use it elsewhere in your application and/or it has more fields than what is shown here.
