Question

当我尝试使用Django进行练习时，URL路径问题失败 ” 提高ImproperlyConfigured（ django.core.exceptions.ImproperlyConfigured：URL路由“ post / Title：Title /”使用无效的转换器“ Title”。 ” 1.我尝试将变量Title更改为其他路径名，但仍然无法正常工作。 2.我检查了setting.py，请帮帮我。

urls.py

from django.contrib import admin
from django.urls import path
from mblog.views import homepage, showpost

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', homepage),
    path('post/<Title:Title>/', showpost),
]

views.py


from django.shortcuts import render, redirect

from django.http import HttpResponse
from .models import Post
from datetime import datetime


# Create your views here.
def homepage(request):
    posts = Post.objects.all()  # SQL SELECT * FROM mblog_post(creat from models)
    now = datetime.now()
    return render(request, 'index.html', locals()) 


def showpost(request, Title):
    try:
        post = Post.objects.get(Title = Title)
        if post != None:
            return render(request, 'post.html', locals())
    except:
        return redirect('/')

Answer 1

在您的urls.py中执行以下操作：

path('post/<str:Title>/', showpost)

Answer 2

您必须尝试执行此操作，这将有助于您解决错误。您不能在主键中传递相同的值名称，而应将“ slug”或“ int”放入

path('post/<slug:Title>/', showpost),

然后在视图中将post变量的参数更改为slug = title。

def showpost(request, Title):
    try:
        post = Post.objects.get(slug= Title)
        if post != None:
            return render(request, 'post.html', locals())
    except:
        return redirect('/')
