我已嘗試更新 url 和對此的看法，但我不斷收到錯誤回應
path("add_page/<str:title>", views.add_page, name="addpage"),
def add_page(request, title):
請告知此錯誤回應可能來自何處，因為上述編輯是我在其他一些 stackoverflow 回應中看到的以清除錯誤的內容，但這對我不起作用。
謝謝
uj5u.com熱心網友回復：
當您重定向到 時entrypage，您需要指定標題，因此：
from django.shortcuts import redirect
def add_page(request):
if request.method == "POST":
form = AddPageForm(request.POST)
entries = util.list_entries()
if form.is_valid():
title = form.cleaned_data['title']
content = form.cleaned_data['content']
util.save_entry(title, content)
for entry in entries:
if title.upper() == entry.upper():
return render(request, "encyclopedia/errorpage.html")
# specify title ↓
return redirect('encyclopedia:entrypage', title=title)
# …我還強烈建議使用資料庫，而不是從實用程式中獲取所有條目：資料庫經過優化以搜索有效，而訪問檔案串列需要線性時間進行搜索。如果你定義了一個資料庫模型，你可以添加db_index=True[Django-doc]來構建一個索引，這可以極大地促進搜索。
