UnboundLocalError：分配前已引用局部变量“ team_members”

Question

我遇到以下错误：

  

UnboundLocalError：之前引用的本地变量'team_members'   作业

默认情况下，模型中的塞子值为1。

这是功能：

def single_slug(request, single_slug):

team = [c.infraTeam_slug for c in infraTeam.objects.all()]
if single_slug in team:
   team_members = TeamMember.objects.filter(infra_team__infraTeam_slug=single_slug)
   series_urls = {}

for m in team_members.all():
    part_one = vulnerability.objects.filter(member_name__member_name=m.member_name).earliest("vulnerabilty_date")
    series_urls[m] = part_one.vulnerability_slug

return render(request=request,
              template_name='main/category.html',
              context={"member_name": team_members, "part_ones": series_urls})

请帮助我解决这个问题。
