Question

我是django的新手，我正在创建一个简单的博客。我刚刚添加了标题＆＃39;，＆＃39; body＆＃39;，＆＃39; date＆＃39;和＆＃39;时间＆＃39;领域。点击保存按钮后，该特定帖子已成功添加＆＃39;但每个帖子的标题仍然是“邮件对象”。我尝试过“管理。制作”和＃39;在manage.py sync之后管理和管理.py迁移命令，但它也没有帮助。

admin.py

from django.contrib import admin
from blog.models import Post
# Register your models here.

class PostAdmin(admin.ModelAdmin):
    search_fields = ["title"]

admin.site.register(Post, PostAdmin)

models.py

from django.db import models

# Create your models here.

    class Post(models.Model):
        title=models.CharField(max_length = 140)
        body=models.TextField()
        date=models.DateTimeField()

    def _unicode_(self):
        return self.title

Answer 1

您需要定义（重载）__unicode__(self)方法（双_）

回答有关python3的问题：

在Python 3上，因为所有字符串本身都被认为是Unicode，所以只能使用 str （）方法（ unicode （）方法已过时）。
