Probably something basic, but cannot seem to figure it out.
I am trying to implement a custom UI for viewflow where the various tasks are displayed as modals. I have managed to get the initial start view to display in a modal and to use AJAX to submit the form. I would like to get all the other process task views to do the same. The following is my attempt based on this answer however, the overridden view AJAXDetailTaskView(DetailTaskView) does not seem to get called and I am wondering where I am going wrong.
In this specific instance I am trying to modify the start detail view (which I presume will be the same principle for all the other views)
flows.py
class AssetFlow(Flow):
process_class = models.AssetProccess
task_class = models.AssetTask
lock_impl = select_for_update_lock
start = (
flow.Start(
views.StartView)
.Permission(auto_create=True)
.Next(this.co_approval)
)
co_approval = (
flow.View(
views.AssetView
)
.Next(this.finance_tc)
)
...
views.py
from viewflow.flow.views.detail import DetailTaskView
class AJAXDetailTaskView(DetailTaskView):
def render_to_response(self, context, **response_kwargs):
if self.request.META.get('HTTP_X_REQUESTED_WITH') == 'XMLHttpRequest':
print('An AJAX request')
return JsonResponse('Success', safe=False, **response_kwargs)
else:
print('Not an AJAZ request')
return super(AJAXDetailTaskView, self).render_to_response(context, **response_kwargs)
class StartView(StartFlowMixin, generic.UpdateView, flow.View):
model = models.Item
form_class = forms.AssetForm
data = dict()
detail_view_class = AJAXDetailTaskView
def get_object(self):
return self.activation.process.asset
def get(self, request, *args, **kwargs):
self.object = None
form_class = self.get_form_class()
form = self.get_form(form_class)
context = self.get_context_data(form=form, data=self.data)
html_form = render_to_string('asset/asset/partial_start.html',
context,
request=request,
)
return JsonResponse({'html_form': html_form})
...
detail_view_class is an attribute of flow.Start not the StartView
