我正在嘗試在 slug:slug url 頂部添加另一個 html 網頁，它會引發錯誤.. 我不知道這里出了什么問題。
已經嘗試了我能想到的一切并且在放棄的邊緣，這里有人可以幫忙嗎？:)

uj5u.com熱心網友回復：
根據您的網址urls.py：
path('<slug:slug>/add-comment/', views.add_comment, name='add-comment')
您需要像這樣編輯視圖：
@login_required(login_url='/accounts/login')
def add_comment(request, slug): # We edited here: pk -> slug
movie = Movie.objects.get(slug=slug) # And we edited here: pk -> slug, twice.
form = CommentForm()
context = {
'form': form
}
return render(request, 'add_comment.html', context)
現在您需要驗證您的 slug 并檢查電影物件是否存在。
from django.http import Http404 # Don't forget this import!
@login_required(login_url='/accounts/login')
def add_comment(request, slug):
try:
movie = Movie.objects.get(slug=slug)
except Movie.DoesNotExist: # We catch exception and raise 404 error, it means that movie with that slug doesn't exist.
raise Http404
form = CommentForm()
context = {
'form': form
}
return render(request, 'add_comment.html', context)
PS 按欄位獲取電影不是一個好主意，這不是必需的，也不是唯一的。例如，您有兩部電影具有相同的標題和 slug（由標題生成）。如果你將這個 slug 傳遞給 url - 你會得到MultipleObjectsReturned例外。
