Question

我的权限类有问题-我不知道为什么向用户添加权限无法按我的意愿工作。我喜欢它如何工作->在单击带有用户列表的站点中的按钮后，他获得了查看下载特定文件的权限。

提供权限的类（在views.py中）：

class GiveBetaPermission(LoginRequiredMixin, AccountTypeRequiredMixin, RedirectView):
   model = BetaSoftware
   account_type_required = ['admin', ]
   url = reverse_lazy('accounts:client-list')
   success_message = _("Permission granted.")

   def get(self, request, *args, **kwargs):
       user = get_object_or_404(User, pk=kwargs.get('pk'))
       perm_name = 'softwares.view_beta'
       perm = Permission.objects.get(

       content_type=ContentType.objects.get_for_model(BetaSoftware),
       codename='view_beta')
       assert perm_name == '{}.{}'.format(perm.content_type.app_label, perm.codename)
       print('check before add:', user.has_perm(perm))
       user.user_permissions.add(perm)
       user.save()
       user = get_object_or_404(User, pk=kwargs.get('pk'))
       print('check after add:', user.has_perm(perm))
       return super(GiveBetaPermission, self).get(request, *args, **kwargs)

型号：

class BetaSoftware(models.Model):
    (some working download code)
            class Meta:
                permissions = (
                    ("view_beta","view_beta"),
            )

表格操作代码（提供访问权限的按钮）

    {% if user.account_type == 'admin' %}
    {% if  not softwares.view_beta %}
        <a href="{% url 'softwares:beta-permission' pk=record.pk %}" data-toggle="tooltip" data-placement="bottom" title="{% trans "Beta test access" %}"><i class="fa fa-fw fa-bold"></i></a>
    {% endif %}
    {% endif %}

经许可即可使用的HTML代码：

{% if softwares.view_beta %}
<div class="card mb-3">
    <div class="card-header">
        <i class="fa fa-table"></i> {% trans "Beta Software" %}
    </div>
    <div class="card-body">
        {% if user_has_licences %}
            <div class="form-group row align-items-center">
                <div class="col-sm-3">{% trans "Download the beta software:" %}</div>
                <div class="col-sm-9">
                    <a href="{% url 'softwares:betadownload' %}" class="btn btn-primary" data-toggle="tooltip" data-placement="bottom" title=""
                       data-original-title="Download software"><i class="fa fa-fw fa-download"></i> {% trans "Download" %}</a>
                </div>
            </div>
        {% else %}
            <div class="form-group row">
                <div class="col-sm-8">{% trans "No available beta software, user have no licenses." %}</div>
            </div>
        {% endif %}
    </div>
</div>
{% endif %}

在Django中添加权限不起作用
