Question

当我尝试访问帖子模型的详细信息页面时，收到该错误。 URL文件中有子弹字段，但这似乎无关紧要。

型号

TYPE_STATUS = (
    ('post', 'Post'),
    ('page', 'Page'),
    ('media', 'Media'),
    ('menu', 'Menu'),
)    

class Post(models.Model):
    title = models.CharField(max_length=70)
    slug = models.SlugField(blank=True, unique=True)
    type_status = models.CharField(max_length=70, default='post', 
    choices=TYPE_STATUS)
    description = models.TextField()
    short_description = models.CharField(max_length=155)
    image = models.ImageField(upload_to=upload_image_path, null=True, blank=True)
    active = models.BooleanField(default=True)
    timestamp = models.DateTimeField(auto_now_add=True)
    featured = models.BooleanField(default=False)

查看

from django.views.generic import DetailView
from django.shortcuts import render
from posts.models import Post

class home_page(DetailView):
    queryset = Post.objects.filter(slug='home', featured=True)
    template_name = "home_page.html"

网址

from .views import home_page

urlpatterns = [
    url(r'^(?P<slug>[\w-]+)/$', home_page.as_view(), name='home'),
]

像这样更改您的网址

DetailView

然后确保您的CBV $file="C:\logtest\log-3.json" add-type -path "C:\logtest\Newtonsoft.Json.dll" $sr=new-object system.IO.StreamReader($file) $reader=new-object Newtonsoft.Json.JsonTextReader($sr) $analyzer=New-Object Newtonsoft.Json.JsonSerializer $analyzer.ReferenceLoopHandling=[Newtonsoft.Json.ReferenceLoopHandling]::Ignore $i=0 $n=0 while($reader.read()){ if($n -gt 2){ if($reader.TokenType.ToString() -eq "StartObject"){ $single=$null $single=$analyzer.Deserialize($reader) # Deal with the json record... $i++ } } $n++ } $reader.Close()中的queryset中有一个值

在Django应用程序中找不到页面错误
