带有参数的get_absolute_url [英] get_absolute_url with parameters

问题描述

我的 urls.py ：

urlpatterns = [
        ...
        url(r'^profile/$', profile.profile, name='profile'),
]

我的模型：

class Reg(models.Model):
    name = models.CharField(max_length=32, primary_key=True)
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, 
        related_name='%(app_label)s_%(class)s_reg', null=True)
    ...

    def get_absolute_url(self):
        return reverse('core:profile', ???)

我的观看次数：

@login_required
def profile(request):
    context_dict = {}
    u = User.objects.get(username=request.user)
    context_dict['user'] = u
    r = reg.Reg.objects.get(user=u)
    context_dict['reg'] = r
    return render(request, 'core/reg.html', context_dict)

是否可以使用get_absolute_url查看不同的配置文件？例如，在/ admin中，当您查看个人资料 John时，单击在站点上查看，并获得包含约翰数据而不是您的个人资料的个人资料页面

Is it possible use get_absolute_url to views different profiles? For example from the /admin when you look the profile "John", you click on the "view on site" and obtain the profile page with john datas, not yours

推荐答案

您的视图必须能够接受额外的参数，最好是用户ID，因为名称通常包含空格：

Your views must be able to accept an extra argument, preferably the user id, since names usually contain spaces:

from django.shortcuts import get_object_or_404

@login_required
def profile(request, user_id):
    context_dict = {}
    u = get_object_or_404(User, pk=user_id)
    context_dict['user'] = u
    r = reg.Reg.objects.get(user=u)
    context_dict['reg'] = r
    return render(request, 'core/reg.html', context_dict)

然后您的 urls.py 变为：

urlpatterns = [
        ...
        url(r'^profile/(?P<user_id>[0-9]+)/$', profile.profile, name='profile'),
]

最后是您的 models.py 和 get_absolute_url 方法：

class Reg(models.Model):
    name = models.CharField(max_length=32, primary_key=True)
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, 
        related_name='%(app_label)s_%(class)s_reg', null=True)
    ...

    def get_absolute_url(self):
        return reverse('core:profile', user_id=self.id)
