我正在尝试在一个应用程序中同时使用django-viewflow和django-permission的想法，其中会有一些复杂的权限规则。我理解 django-permission 工作方式的方式是向要应用权限规则的视图添加装饰器。
通过扩展基本视图流视图并将 urls.py 指向扩展视图，我已设法在流程视图上进行此操作。当我尝试对任务遵循相同的想法时，我遇到了下面列出的错误
类型对象“CBVTask”没有属性“flow_class”
模型.py
class CBVArticle(models.Model):
created_by = models.ForeignKey(User)
title = models.CharField(max_length=100)
content = models.TextField()
class CBVArticleProcess(Process):
article = models.ForeignKey(CBVArticle, blank=True, null=True)
class CBVTask(Task):
class Meta:
proxy = True
流.py
class CBVArticleFlow(Flow):
process_class = models.CBVArticleProcess
task_class = models.CBVTask
start = (
flow.Start(views.ArticleCreate).Next(this.end)
)
end =flow.End()
网址.py
myflow_urls = FlowViewSet(CBVArticleFlow).urls
urlpatterns = [
url(r'^process/(?P<process_pk>\d+)/$', views.TestDetailProcessView.as_view(), kwargs = dict(flow_class=CBVArticleFlow), name='detail'),
url(r'^process/(?P<process_pk>\d+)/start/(?P<task_pk>\d+)/detail/$', views.DetailTaskView.as_view(), kwargs = dict(flow_class=CBVArticleFlow, flow_task=CBVTask), name='start__detail'),
]
视图.py
from viewflow.flow.views import DetailProcessView as BaseDetailProcessView, DetailTaskView as BaseDetailTaskView
@permission_required('test_app_cbv.view_cbvarticleprocess')
class TestDetailProcessView(BaseDetailProcessView):
template_name = 'test_app_cbv/detail.html'
def get_queryset(self):
pk = self.kwargs['process_pk']
return models.CBVArticleProcess.objects.filter(process_ptr_id = pk)
class DetailTaskView(BaseDetailTaskView):
template_name = 'test_app_cbv/task_detail.html'
提前感谢您的任何指点！
