TemplateDoesNotExist at /file_name 在 django 中出錯

Question

我正面臨這個問題，我相信我已經做了我應該做的一切。

這是我的settings.py

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

嘗試編寫一個簡單的函數視圖來呈現索引或登錄頁面。

def index(request):
    return render(request, 'interconcept/index.html')

每當我運行服務器並嘗試訪問該網頁時，我都會收到此錯誤。

我已將我的應用程序添加到 settings.py。 我所指的文件存在。 我的模板文件夾有一些其他文件夾，這樣做是為了使我的代碼更整潔且易於調試。

我在模板下有以下文件夾 - interconcept、blog 和 partials。 Partials 由_alert.html、_navbar.html 和_footer.html 組成。interconcept 文件夾由index.html 和其他一些html 文件組成。

我認為問題在於我的目錄搞砸了。 它似乎正在影響其他事情。

Answer 1

您需要通過應用程序名稱引用模板文件。 似乎您的項目名稱是interconcept而您的應用名稱是interconceptapp 。

def index(request):
    return render(request, 'interconceptapp/index.html')

假設您已將index.html放置在模板目錄下名為interconceptapp的文件夾中，並使用 in interconceptapp 。
