Question

有点像标题所说的...检查图片。当我尝试发布新帖子时，它说我成功了，但它不会显示在管理页面或detail.html中。

这是我的帖子模型代码

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse



class Post(models.Model):
    title = models.CharField(max_length=100)
    slug = models.SlugField(help_text="A short label, generally used in URLs.",default='', max_length=100)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')
    content = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now)
    author = models.ForeignKey(User, on_delete=models.CASCADE)

    class Meta:
        ordering = ['-date_posted']

    def save(self):
        slug = self.title

    def get_absolute_url(self):
        return reverse('detail', kwargs={'slug':self.slug})

    def __str__(self):
        return self.title

admin.py

from django.contrib import admin
from .models import Post

class PostAdmin(admin.ModelAdmin):
    list_display = ['title', 'slug', 'date_posted', 'author']
    list_filter = ['title', 'date_posted']
    prepopulated_fields = { 'slug': ('title',)}

admin.site.register(Post, PostAdmin)

名为Blog的应用程序中的 ~~views.py是否也具有模型发布~~

from django.contrib import messages from . models import Post from django.core.mail import send_mail from django.views.generic import DeleteView, ListView def index_view(request): return render(request, 'blog/index_view.html') def blog_view(request): context = { 'posts': Post.objects.all() } return render(request, 'blog/blog_view.html', context) class PostDetailView(DeleteView): model = Post template_name = 'blog/detail.html' context_object_name = 'post'

如果您需要我的其他任何代码，请将其发布

Answer 1

您实际上并没有使用save(self)方法保存数据：

def save(self):
    slug = self.title
    super(Post, self).save(*args, **kwargs)

您应按文档中所述调用真正的save方法：

Overriding predefined model methods

当我在Django中通过管理页面发帖时，它没有显示
