我正在通過此Getting started with Django Rest Framework by Building a Simple Product Inventory Manager教程工作。在最後的教程中,它說我「現在應該能夠運行你的服務器並開始使用不同的API端點」。但是,當我運行服務器時,我得到的是一個TemplateDoesNotExist錯誤。在教程中沒有提到創建模板(這最終將連接到Angular 2前端,如this tutorial所示),所以我很困惑這是否是我的代碼中的錯誤,或者如果教程離開了一步。當我運行我的代碼時,我沒有遇到任何控制檯錯誤。django - TemplateDoesNotExist錯誤

如果你需要看到更多的我的代碼,請評論,我會發布,但一切都應該與教程中給出的代碼相同。
改變了錯誤我得到,至少。現在它顯示「OperationalError at/products/no such table:inventory_product」。我認爲這僅僅意味着我需要向表中添加數據? – rustbird
不可以。您已在數據庫級別首先創建表。 –
使用「python manage.py makemigrations」和「python manage.py migrate」 –
