Mac您的

path（“”，views.car\u detail，name='car\u detail'），

需要一个参数

id

“{%url'car\u detail'car.id%}”，需要是

“{%url'car\u detail'each\u car.id%}”

谢谢@ha neul。明显的疏忽。这解决了你的

路径（“”，views.car\u detail，name='car\u detail'），

需要一个参数

id

“{%url'car\u detail'car.id%}”，需要是

“{%url'car detail'each\u car.id%}”

谢谢@ha neul。明显的疏忽。这解决了汉克斯的问题。这就解决了，谢谢。这就解决了问题。
