下記のサイトを参考にして、解決方法を模索しました。

・views.pyのTemplateViewを使うこと
|
|

|
+
|
|

|
+
[Django でまず覚えたい TemplateView のパターン](https://qiita.com/ytyng/items/7cb3c3a5605974151678)

・Methodにより、クエリセットの処理方法をフィルターに指示する
|
|
14
|
+
|
|
15
|
+
[Django フィルターリファレンス](https://django-filter.readthedocs.io/en/latest/ref/filters.html?highlight=method#method)
|
|

|
+
|
|

|
+
・Methodによる検索条件の設定方法
|
|
18
|
+
|
|
19
|
+
[django-filterで検索用パラメータを受け取り加工してから検索する方法](https://teratail.com/questions/131200)

|
20
|
+
|
|
21
|
+
|
|

|
+
|
|

|
+
たどり着いたのが、filter.pyで、Methodによりfilterに関数を付与する方法です。
|
|
24
|
+
|
|
25
|
+
しかし、実行すると「AssertionError at /
|
|
26
|

|
27
|
+
Expected 'ItemFilter.age' to return a QuerySet, but got a NoneType instead.」
|
