Question

我有一个模型表单，用于保存更改请求，并在创建新条目时通过电子邮件通知管理员。管理员获取并通过链接进行温和通知，以查看条目http://mydjango/admin，然后他们登录查看并批准或拒绝请求。管理员希望上面的链接将它们直接带到条目而不是管理站点，让他们浏览条目列表以找到最新的条目。我不得不说，我是django的新手，并希望看看这是否可行。我注意到，如果我转到某个条目并单击它，我的浏览器上的链接就会有一个唯一的编号，例如：http://127.0.0.1:8000/admin/app/changerequests/61/change/

每个条目都有61个更改。所以我想的可能包括那个＆＃34; id＆＃34;发送给管理员的电子邮件中新创建的条目。

她是我的模特，形式，观点，管理员

Answer 1

我无法看到您在该电子邮件中包含任何类型的链接的位置，但您当然可以使用reversing admin urls功能创建指向您的内容的链接。

from django.core.urlresolvers import reverse

...

if form.is_valid():
    item = form.save()
    link = reverse('admin:app_changerequests_change', args=(item.id,))
    url = "https://ADDRESS_OF_MY_SITE{}".format(link)

您可以在电子邮件中加入url值。

Answer 2

就像你的模型一样，它是一样的。所以，你可以传递id或pk。

据您所知，Django始终在每个模型中添加id字段以获得唯一性，pk表示您的主键字段。因此，您可以将任何字段分配给主键（默认情况下，它分配给id字段）。所以，您曾经为任何一个字段指定了主键。然后，当你致电pk时。它将返回主键字段的值。

希望它会对你有所帮助。：）

Answer 3

您可以使用

获取模型对象的正确管理员更改网址

reverse('admin:app_model_change', args=(model_object.id))

在您的电子邮件中发送网址。

Django MySQL条目唯一ID或pk
