Django - 从配置文件模型返回完整名称，该模型与其他模型中的 Django 用户模型相关

Question

我创建了 Book、Book_stat 一个与 Django User 模型相关的 Profile 模型，我正在尝试将Book title和Profile中的full_name显示为默认的str返回字符串，来自Book_stat

models.py

from django.db import models
from django.contrib.auth.models import User
from decimal import Decimal

# Create your models here.
class Book(models.Model):
    title = models.CharField(max_length=200)

    def __str__(self):
        return self.title

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    full_name = models.CharField(max_length=150)

    def __str__(self):
        return self.full_name

class Book_stat(models.Model):
    user = models.ForeignKey(User)
    book = models.ForeignKey(Book)
    rating = models.DecimalField(max_digits=5, decimal_places=2, default=Decimal('0.00'))
    like = models.BooleanField(default=False)

    def __str__(self):
        return self.book.title # here i would like to return book title + full_name from Profile Model 

admin.py

from django.contrib import admin
from .models import Book, Book_stat, Profile
# Register your models here.
admin.site.register(Book)
admin.site.register(Book_stat)
admin.site.register(Profile)    

当我在 django 管理页面中单击 Book_stat 时，我想在我的 中显示 Book title 和 Profile full_name 作为标题>Book_stat列表

Answer 1

    def __str__(self):
        return self.book.title +' '+ self.user.profile.full_name

试试这个希望你能得到它
