[英]Django UpdateView, get the current object being edit id?
我試圖讓當前記錄被編輯的id,但到目前為止失敗了。 我的觀點如下:
views.py
class EditSite(UpdateView):
model = SiteData
form_class = SiteForm
template_name = "sites/site_form.html"
@method_decorator(user_passes_test(lambda u: u.has_perm('config.edit_subnet')))
def dispatch(self, *args, **kwargs):
self.site_id = self.object.pk
return super(EditSite, self).dispatch(*args, **kwargs)
def get_success_url(self, **kwargs):
return reverse_lazy("sites:site_overview", args=(self.site_id,))
def get_form_kwargs(self, *args, **kwargs):
kwargs = super().get_form_kwargs()
return kwargs
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['SiteID']=self.site_id
context['SiteName']=self.location
context['FormType']='Edit'
return context
和錯誤:
File "/itapp/itapp/sites/views.py" in dispatch
890. self.site_id = self.object.pk
Exception Type: AttributeError at /sites/site/edit/7
Exception Value: 'EditSite' object has no attribute 'object'
我試過了:
self.object.pk
object.pk
self.pk
視圖的對象屬性在getUpdateView的get / post期間設置:
def get(self, request, *args, **kwargs):
self.object = self.get_object()
return super(BaseUpdateView, self).get(request, *args, **kwargs)
def post(self, request, *args, **kwargs):
self.object = self.get_object()
return super(BaseUpdateView, self).post(request, *args, **kwargs)
因此,在dispatch
方法中尚不可用。 但它將在get_success_url
和get_context_data
方法中可用,因為它們在get / post之后發生。 所以你可以這樣做:
from django.contrib.auth.mixins import PermissionRequiredMixin
class EditSite(PermissionRequiredMixin, UpdateView):
model = SiteData
form_class = SiteForm
template_name = "sites/site_form.html"
permission_required = 'config.edit_subnet'
def get_success_url(self, **kwargs):
return reverse_lazy("sites:site_overview", args=(self.object.site_id,))
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['SiteID']=self.object.site_id
context['SiteName']=self.location # <--- where does self.location come from? self.object.location perhaps?
context['FormType']='Edit'
return context
