django勉強中のものです。  
今、画像投稿の機能をつけようとして、adminページからは登録できるようになったのですが、普通のフォームから投稿しようとすると、できない状態です。  
具体的には、下記のようなフォームで画像選択はできるのですが、送信を押してしまうと、画像が選択されていませんと出てしまいます。

[![入力段階では選択されていますが](https://i.stack.imgur.com/iIVLh.png)](https://i.stack.imgur.com/iIVLh.png)  
[![送信を押すと保存されていません。実際ディレクトリにも保存されていません。](https://i.stack.imgur.com/Akjca.png)](https://i.stack.imgur.com/Akjca.png)

環境  
dockerで構築  
python3.7.3  
django2.1.1  
pillow:pipでインストール済み

コードは以下のとおりです。

question
django
django2.1.1で画像投稿がうまくできない。


自己解決しました。  
formタグの１つ目の要素にenctype="multipart/form-data"をつけたら行けました。  
ちなみに、2つ目以降につけるとだめだったので、Ⅰつめじゃないと行けないようです。
