[英]How can I add a new field from the other app's models.py to html in Django, Python
我想換個領域。
我有預訂應用程序的 email.html 和訂單應用程序的 order_detail.html。 這兩個文件都有一個詞苗圃信息：在頁面的底部。
我想在兩個 html 文件的 Nursery 信息下使用服務應用程序中的 Nursery 字段。
我寫了 order.nursery 但它沒有出現。 另一個像 order.shippingAddress1 可能會出現。 我怎樣才能像其他人一樣顯示 order.nursery？
我的關系應用程序名稱是預訂、訂單、服務。
這是預訂應用程序模板的 email.html。

我真的很感謝你每次的好意。 如果我必須顯示其他文件，請教我。
由於nursery是順序model class中的ForeignKey。 這意味着 Nursery model class 與訂單class 具有一對多關系。 為了訪問 html 文件中的 Nursery model class 屬性，您可以使用訂單 ZA8CFDE6331BD59EB266696
For Example:
order.nursery.name: This would return the name of Nursery.
以類似的方式，您可以訪問 html 文件中的所有其他 Nursery 屬性。
