TemplateSyntaxError at / Could not parse the remainder: 'product.tk' from ''main-product-detail'product.tk'

Question

我被困在一个我大部分时间都解决的问题上，但是现在，当我将链接放在产品详细信息页面的 home.html 文件中时，出现错误：TemplateSyntaxError at / 无法分析其余部分：''main-product-detail'product.tk'的'product.tk'我到处检查并修改了东西但没有改变。

看看我的代码，告诉我错误在哪里

问题就在这里

<a href="{% url 'product-detail'product.tk %}"> 

改了好几次都没有定下来

Answer 1

在 Django 模板中，

url

是一个函数，它需要一个或多个用空格分隔的参数。在您的情况下，第一个参数是一个字符串：端点的名称，第二个是存储在

product.tk

变量中的主键。你只需要在它们之间放一个空格就可以了：

<a href="{% url 'main-product-detail' product.tk %}"> 

注意：检查模板中产品详细信息的端点名称。在

urls.py

中，您将其命名为

main-product-detail

，但有时您只使用

product-detail

。
