python - Django - 表单：“模块”对象不可调用错误

Question

我正在尝试更新表中的几行。和这个问题一样。我为我的项目修改了代码并试图解决它几天，但它对我不起作用。首先，我在表单中显示 html 页面中的所有现有行。如果是 POST 请求，则尝试保存到数据库中。我这里有 2 个错误。1.如果我使用return render_to_response('module.html',{'modules' : modules})它会像我想要的那样在 html 页面中显示数据，但是当单击保存按钮时，它会在 POST 请求中给出以下错误：

Forbidden (403)
CSRF verification failed. Request aborted.

Help
Reason given for failure:
CSRF token missing or incorrect.

2. 如果我使用return render(request, 'module.html',{'modules' : modules})，它甚至没有显示数据，只是在 GET 请求上给出以下错误：

你能帮我找出我的代码有问题吗？
