构建一个Employee应用程序，使用表单更新Employee之后，它仅显示此错误，并且URL似乎正确，因此我可以说出错误的来源
我已经在表单中对所有的URL模式，视图和URL进行了交叉检查，还尝试使用this question中的解决方案，这给了我更大的错误
urls.py
urlpatterns = [
path('edit/<int:pk>/', views.edit, name = 'edit'),
]
views.py

logging.info(type(employ))

}

它应该被提交并路由到edit.hmtl，以防在提交时出现任何错误
答案 0 :(得分：1)
当您重定向到edit视图时，您需要传递主键。
return redirect('edit', pk=employ.pk)
顺便说一句，不建议直接从request.POST访问值。看看Django表单。

没什么改变表格
<form method = 'POST' action="{% url 'edit' pk=employ.pk %}" class="m-b-30" enctype="multipart/form-data">
到
<form method = 'POST' action="" class="m-b-30" enctype="multipart/form-data">
并将渲染到
return render(request, 'employees/edit.html', context)
