我正在尝试使用上下文将一些数据导入到我的HTML中 现在我的代码是以下，并且工作得很好。 我正在使用Try / Except，因为并不总是创建项目而且kwargs ['pk1']）并不总是存在：
我的工作代码：
class ProjectDetailView(generic.DetailView, LoginRequiredMixin):
#import pdb; pdb.set_trace()
model = Project
template_name = 'project_details.html'
def get_object(self, queryset=None):
return get_object_or_404(Project,id=self.kwargs['pk1'])
def get_context_data(self, **kwargs):
context = super(ProjectDetailView, self).get_context_data(**kwargs)
try:
team_name = Project.objects.get(id=self.kwargs['pk1']).team_id.members.all()
context['team_name'] = team_name
except AttributeError:
pass
return context
那就是我想在那个上下文中添加另一个密钥对，从那里我总是得到一个
Reverse for 'team_select' with keyword arguments '{'pk1': ''}' not found.
1 pattern(s) tried: ['website/project/(?P<pk1>[0-9]+)/linkteam2/$']
我试过了：
def get_context_data(self, **kwargs):
context = super(ProjectDetailView, self).get_context_data(**kwargs)
try:
team_name = Project.objects.get(id=self.kwargs['pk1']).team_id.members.all()
team_score = get_team_cohesivenss_score(self)
m_context = {'team_name':team_name,
'team_score':team_score
}
context = m_context
except AttributeError:
pass
return context
任何想法？
