我在NarrateUpdate视图上出现属性错误。我想编辑/更新表单中的用户提交
这是我的views.py:
class NarrateUpdate(SuccessMessageMixin, UpdateView):
model = Narrate
fields = ['title', 'body']
template_name = 'narrate_update_form.html'
success_url = reverse_lazy('narrate-status')
success_message = "Narration successfully updated"
def get(self, request, *args, **kwargs):
footer = FooterLinks.objects.all()
context = self.get_context_data(**kwargs)
context['footer'] = footer
return self.render_to_response(context)
urls.py
path('narration/<int:pk>/update/', NarrateUpdate.as_view(), name='edit-narration'),
这是models.py:
class Narrate(models.Model):
STATUS = (
('F', 'FOR REVIEW'),
('P', 'PASSED'),
)
title = models.CharField(max_length=255)
body = models.CharField(max_length=10000)
status = models.CharField(
max_length=25, choices=STATUS, default='for_review', blank=True)
def __str__(self):
return self.title
def get_absolute_url(self):
return "/narration/%i/" % self.title
class Meta:
verbose_name = "narration"
verbose_name_plural = "narrations"
我该怎么做才能使这项工作成功?
答案 0 :(得分:1)
您为什么要覆盖get
方法?如果您想添加footer
更好地使用get_context_data()
方法:
class NarrateUpdate(SuccessMessageMixin, UpdateView):
model = Narrate
fields = ['title', 'body']
template_name = 'narrate_update_form.html'
success_url = reverse_lazy('narrate-status')
success_message = "Narration successfully updated"
def get_context_data(self, **kwargs):
context = super(NarrateUpdate, self).get_context_data(**kwargs)
context['footer'] = FooterLinks.objects.all()
return context
