我有一些問題,我可以上傳文本字段'文本'和字段'視頻',我在其中放置一個URLField,問題是,從管理面板我可以上傳圖像沒有任何問題。但從CreateView的角度來看,我是不可能的。如何在我的帖子上用CreateView上傳圖片?
我被告知需要在窗體中添加標籤(enctype =「multipart/form-data」),它可以工作,但不是將其上傳到/media/posts/image.jpg,而是嘗試將其上傳到(/media/image .jpg),並且它的結尾都是它不會上傳圖像。
我真的只是想把圖片上傳到我的帖子中,你可以在這裏看到https://plxapp.herokuapp.com/,後來用的是頭像和UserProfile的頭部。
如果他們有任何程序或驗證應該完成,他們可以告訴我這裏。
我離開我的代碼:

爲什麼你再次在模型表單中聲明字段? –
