Django Viewflow 使用基于类的视图但出现错误：找不到“索引”的反向。 “索引”不是有效的视图函数或模式名称

Question

我正在为我的 Django 视图流项目使用基于类的视图。但是我收到以下错误：

未找到“索引”的反向。 'index' 不是有效的视图函数或模式名称

这是我的课程：

rules/flows.py

class MyFlow(Flow):
    """
    My App Flow
    """
    process_class = models.MyProcess

    start = flow.Start(
        views.MyDetailView,
        fields=["rule"],
        task_title="New Task"
    ).Permission(
        auto_create=True
    ).Next(this.end)

    end = flow.End()

规则/urls.py

rule_urls = FlowViewSet(MyFlow).urls

urlpatterns = [
     url(r'^rule/', include(rule_urls, namespace='rule')),
     url(r'^(?P<pk>\d+)/mydetail/', MyDetailView.as_view(), {'flow_class': MyFlow, 'flow_task': MyFlow.start}, name='mydetail')
]

规则/models.py

class SubRules(models.Model):
    rule_id = models.AutoField(primary_key=True)

    class Meta:
        db_table = 'sub_rules'


class EntRules(models.Model):
    rule = models.OneToOneField(SubRules, primary_key=True, on_delete=models.CASCADE)
    entitlement_code = models.IntegerField()
    rule_approved = models.SmallIntegerField()
    rule_approved_datetime = models.DateTimeField(null=True)
    class Meta:

class MyProcess(Process):
    entrule = models.ForeignKey(EntRules, blank=True, null=True, on_delete=models.CASCADE)
    class Meta:
        permissions = (
                       ('approve_ent_rules','Can approve ent_rules')
                      )

规则/forms.py

class MyDetailForm(forms.ModelForm):

    def __init__(self, *args, **kwargs):
       pk = kwargs.pop('rule_id', None)
       super(MyDetailForm, self).__init__(*args, **kwargs)
       sub_rule = SubRules.objects.get(rule_id=pk)
       self.fields['rule'].queryset = sub_rule.objects.filter(rule_id=pk)

class MyDetailView(StartFlowMixin, generic.UpdateView):

    layout = Layout(
        Fieldset('Rule Details',
                 Row('rule',),
                 Row('entitlement_code',),

    )

    def activation_done(self, form):

    def get_object(self):
        return self.activation.process.entrule


    def get_form_kwargs(self):

        pk = int(self.kwargs['pk'])
        kwargs['rule_id'] = pk
        return kwargs

规则/模板/规则/my_detail.html

{% extends "base.html" %}
{% load material_form %}

{% block content %}
    <form method="POST">
        {% csrf_token %}
        <div class="row">
            {% form form=form %} {% endform %}
            {{ activation.management_form }}
            <div class="right">

            </div>
        </div>
   </form>
{% endblock %}

你能告诉我这里可能是什么问题吗？

我看了Process Views outside viewflow.frontend

但是，如何将 sub_rule pk "^(?P\d+)" 传递给 startview，如下面的 URL 所示？

class MyFlow(Flow):
    start = flow.Start(detail_view_class=MyDetailTaskView)

请指教。

您可以将自定义详细视图作为参数传递给 flow.Start http://docs.viewflow.io/viewflow_flow_nodes.html#viewflow.flow.StartFunction.detail_view
