如何用初始数据将django的通用CreateView子类化？
|
我正在尝试创建一个对话框，该对话框使用jquery的.load（）函数以呈现的django形式进行显示。 .load函数将传递“ alert”对象的pk。类函数中还提供了诸如
self.request.user
class Message(models.Model):
user = models.ForeignKey(User)
alert = models.ForeignKey(Alert)
date = models.DateTimeField()
message = models.TextField()
class MessageDialogView(CreateView):
\"\"\" show html form fragment \"\"\"
model = Message
template_name = \"message.html\"
def get_initial(self):
super(MessageDialogView, self).get_initial()
alert = Alert.objects.get(pk=self.request.POST.get(\"alert_id\"))
user = self.request.user
self.initial = {\"alert\":alert.id, \"user\":user.id, \"message\":\"test\"}
return self.initial
def post(self, request, *args, **kwargs):
super(MessageDialogView, self).post(request, *args, **kwargs)
form_class = self.get_form_class()
form = self.get_form(form_class)
context = self.get_context_data(form=form)
return self.render_to_response(context)
self.initial
post
message.html

应该只返回字典，而不会被setting3设置困扰。 您的方法应如下所示：def get_initial(self): # Get the initial dictionary from the superclass method initial = super(YourView, self).get_initial() # Copy the dictionary so we don\'t accidentally change a mutable dict initial = initial.copy() initial[\'user\'] = self.request.user.pk # etc... return initial寇剩
中的dict。 在解决问题方面，我对您似乎在ѭ11中做了多少感到有些怀疑–您可以使用默认值（非替代）ѭ11尝试一下吗？ 您还可以使用（或打印语句）检查的值，确保已设置。搁手
from django.shortcuts import HttpResponseRedirect class PostCreateView(CreateView): model = Post fields = (\'title\', \'slug\', \'content\', \'category\', \'image\') template_name = \"create.html\" success_url = \'/\' def form_valid(self, form): self.object = form.save(commit=False) self.object.user = self.request.user self.object.save() return HttpResponseRedirect(self.get_success_url())
