Django：提交表单中的输入字段未显示

Question

所以我开始将表单模型切换到类基础视图。在EpisodeInfoView 中，当我在pod_funnel.py 的get 方法中在if podcast 下评论或取消评论production = Production.objects.create(podcast=podcast) 时，它会显示表单并让我填写字段但是当我在管理员下签入Productions ，它显示正在使用 Podcast 名称创建作品（从其 ForeignKey 中提取）but without the rest of the info (episode number, episode guest, episode title, etc...) 如果我删除并添加它以在帖子中创建对象，它会向我显示表单，但它什么也不做它显示任何错误。

pod_funnel.py 查看：

class EpisodeInfoView(LoginRequiredMixin, View):
    form_class = EpisodeInfoForm
    template_name = 'pod_funnel/forms_episode_info.html'

    def get(self, request, *args, **kwargs):

        initial_values = {}
        user = request.user

        # Lets get client and podcast for the user already. if not existent raise 404
        client, podcast = get_podfunnel_client_and_podcast_for_user(user)
        if client is None or podcast is None:
            raise Http404

        if podcast:
            initial_values['podcast_name'] = podcast.name
            initial_values['podcast_id'] = podcast.id
            production = Production.objects.filter(podcast=podcast).first()
            # production = Production.objects.create(podcast=podcast)

            if production:
                initial_values['episode_number'] = production.episode_number
                initial_values['episode_title'] = production.episode_title
                initial_values['episode_guest_first_name'] = production.episode_guest_first_name
                initial_values['episode_guest_last_name'] = production.episode_guest_last_name
                initial_values['episode_guest_twitter_name'] = production.episode_guest_twitter_name
                initial_values['episode_summary'] = production.episode_summary

        form = self.form_class(initial=initial_values)
        return render(request, self.template_name, {'form': form})

    def post(self, request, *args, **kwargs):
        form = self.form_class(request.POST)

        if form.is_valid():
            # lets get the data
            # podcast_id = form.cleaned_data.get('podcast_id')
            production_id = form.cleaned_data.get('production_id')
            episode_number = form.cleaned_data.get('episode_number')
            episode_title = form.cleaned_data.get('episode_title')
            episode_guest_first_name = form.cleaned_data.get('episode_guest_first_name')
            episode_guest_last_name = form.cleaned_data.get('episode_guest_last_name')
            episode_guest_twitter_name = form.cleaned_data.get('episode_guest_twitter_name')
            episode_summary = form.cleaned_data.get('episode_summary')


            user = request.user

            # Get the production
            # podcast = get_object_or_404(Podcast, id=podcast_id)
            production = get_object_or_404(Production, id=production_id)

            # Lets see if we have client and podcast for the user already
            client, podcast = get_podfunnel_client_and_podcast_for_user(user)

            if production is None:
                production = Production.objects.create(podcast=podcast)
            production.episode_number = episode_number
            production.episode_title = episode_title
            production.episode_guest_first_name = episode_guest_first_name
            production.episode_guest_last_name = episode_guest_last_name
            production.episode_guest_twitter_name = episode_guest_twitter_name
            production.episode_summary = episode_summary
            production.save()

            # TODO: Needs to redirect to next step
            return HttpResponseRedirect(reverse('podfunnel:episodeimagefiles'))

        return render(request, self.template_name, {'form': form})

episode_info.py 表单：

class EpisodeInfoForm(forms.Form):

    podcast_name = forms.CharField(widget=forms.Field.hidden_widget, required=False, max_length=100, disabled=True)
    podcast_id = forms.IntegerField(widget=forms.Field.hidden_widget)

    production_id = forms.IntegerField(widget=forms.Field.hidden_widget, required=False)

    id = forms.IntegerField(widget=forms.Field.hidden_widget)

    episode_number = forms.IntegerField(widget=forms.NumberInput, required=True)
    episode_title = forms.CharField(max_length=255, required=True)
    episode_guest_first_name = forms.CharField(max_length=128)
    episode_guest_last_name = forms.CharField(max_length=128)
    episode_guest_twitter_name = forms.CharField(max_length=64)
    episode_summary = forms.CharField(widget=forms.Textarea)

我会考虑使用 CreateView/UpdateView 和初始数据字典来设置值，然后将保存功能移动到表单本身。这样视图就小了很多，逻辑在表单中。

这对于管理员来说是类似的： https://djangosnippets.org/snippets/1727/
