我最近在使用 FormView 时遇到了问题,发现这样做的方法是使用 get_form_kwargs。
这是我的代码:
class InternalResetPasswordView(FormView):
template_name = 'reset_password.html'
form_class = forms.InternalPasswordResetForm
# success_message = "Password was reset successfully"
# To get request object

def get_form_kwargs(self):
kwargs = super(InternalResetPasswordView, self).get_form_kwargs()
kwargs['user'] = self.request.user
return kwargs
def get_success_url(self):
return reverse('user-detail', kwargs={'pk': self.request.user.id})
@method_decorator(login_required)
def dispatch(self, *args, **kwargs):
return super(InternalResetPasswordView, self).dispatch(*args, **kwargs)
'''
def get_context_data(self, **kwargs):
context = super(InternalResetPasswordView, self).get_context_data(**kwargs)
context['InternalPasswordResetForm'] = context.get('form')
return context
def get_form_kwargs(self):
kwargs = super(InternalResetPasswordView, self).get_form_kwargs()
kwargs['request'] = self.request
return kwargs
'''
# self.request.user method obtained from
# https://docs.djangoproject.com/en/dev/topics/class-based-views/generic-editing/
def form_valid(self, form):
current_password = form.cleaned_data['old_password']
new_password = form.cleaned_data['new_password1']
confirm_new_password = form.cleaned_data['new_password2']
user = self.request.user
if user.check_password(current_password) and new_password == confirm_new_password:
user.set_password(new_password)
user.save()
# form.valid() redirects to get_success_url
return super(InternalResetPasswordView, self).form_valid(form)
看了这篇文章后,我仍然不明白为什么必须使用 get_form_kwargs 以及为什么在这种情况下使用 self.request 而不是 self.request.user 会给出__init__() got an unexpected keyword argument 'request'
。
有人可以向我解释一下吗?
感谢所有的帮助:)
