Django: how to get value from model in view - django

Question

I have a view that will conditionally display a breadcrumb trail based on the value of the object's "status" field. This works if I manually set the status value (ex status = "completed"). However, as a newbie, I can't figure out how to retrieve the value?
status = Project.status is not working.
Here is the view:
class CompanyProjectsDetailView(DetailBreadcrumbMixin, UpdateView):
model = Project
queryset = Project.objects.get_with_counted_notes_documents_todos()
template_name = 'company_accounts/project_detail.html'
context_object_name = 'project'
form_class = ProjectStatusForm
status = Project.status
if status == "completed":
#cached_property
def crumbs(self):
return [
("projects", reverse(
"company_project:" + CompanyProjects.list_view_name, )
),
(f"completed projects", reverse(
"company_project:" + CompanyProjects.list_view_name, )
),
]

I figured out a way to get this to work. The key is getting the instance in the crumbs method. I imagine there may be a more elegant way to accomplish this.
The working view:
class CompanyProjectsDetailView(DetailBreadcrumbMixin, UpdateView):
model = Project
queryset = Project.objects.get_with_counted_notes_documents_todos()
template_name = 'company_accounts/project_detail.html'
context_object_name = 'project'
form_class = ProjectStatusForm
# pk_url_kwarg = 'project_id'
#cached_property
def crumbs(self):
project = self.get_object()
if project.status == "completed":
return [
("projects", reverse(
"company_project:" + CompanyProjects.list_view_name, )
),
(f"completed projects", reverse(
"company_project:completed_projects" )
),
(f"{project.title}",
reverse(
"company_project:" + CompanyProjectsDetailView.detail_view_name,
kwargs={'pk': project.id})
),
]
elif project.status == "paused":
return [
("projects", reverse(
"company_project:" + CompanyProjects.list_view_name, )
),
(f"paused projects", reverse(
"company_project:paused_projects" )
),
(f"{project.title}",
reverse(
"company_project:" + CompanyProjectsDetailView.detail_view_name,
kwargs={'pk': project.id})
),
]
else:
return [
("projects", reverse(
"company_project:" + CompanyProjects.list_view_name, )
),
(f"{project.title}",
reverse(
"company_project:" + CompanyProjectsDetailView.detail_view_name,
kwargs={'pk': project.id})
),
]
