Django static 文件從模板工作，但不是從 CSS 文件

Question

我剛剛回到 Django，我在開發服務器中設置了一個新項目。 我設置了 static 文件並且我已經能夠從模板加載文件但是當通過 CSS 訪問文件時出現 404 錯誤。 以下是在 CSS 中訪問圖像的方式：

background-image: linear-gradient(rgba(206, 27, 40, 0.25), rgba(206, 27, 40, 0.25)), url(../images/cta01.jpg);

瀏覽器中的 404 錯誤正在查找 staic/images/ 文件夾，但未提供他的位置。 我知道這個 static 文件的事情總是很棘手，但我不記得以前是這樣的問題。 我究竟做錯了什么？ 這是設置文件和主 URL 文件。

我也嘗試使用白噪聲，它似乎工作但行為相同：static 文件在模板中加載，但不是從 CSS 加載。

Answer 1

使用絕對 URL指向應用程序中的任何 static 文件。

設置.py

...
STATIC_URL = '/static/'

當您的設置中有STATIC_URL = '/static/'時。 所以你可以這樣的東西是 css

樣式.css

url('/static/images/cta01.jpg');

Answer 2

有同樣的問題，嘗試添加settings.py

STATICFILES_DIRS = ["C:/Users/user/mysite/djangoapp/static"]

（您電腦中 static 文件的路徑）。

為我工作！
