TypeError： 'NoneType'オブジェクトは添え字付きではなく、その後にAttributeError： 'NoneType'オブジェクトには 'split'属性がありません

Question

djangoを使用しています。

class Postagem(models.Model): 
id = models.AutoField(primary_key=True, editable=False) 
descricao = models.CharField(max_length=50) 
area = models.ForeignKey('core.Area', null=True) 
user = models.ForeignKey('User') 
categoria = models.CharField(max_length=50, null=True) 
post = models.FileField(upload_to='posts/', null=True) 
thumbnail = models.FileField(upload_to='posts/', null=True) 


def __str__(self): 
    return self.descricao 

次の形式：：

class PostForm(forms.ModelForm): 
categoria = forms.ChoiceField(choices=[("Video","Vídeo"),("Audio","Aúdio"),("Imagem","Imagem"),("Musica","Música")], required=True) 
thumbnail = forms.FileField(required=False) 

class Meta: 
    model = Postagem 
    fields = ['descricao', 'area', 'user', 'post'] 

ビュー：

def profileView(request): 
context = getUserContext(request) 

if request.method == 'POST': 
    exception=None 
    userDict = {} 
    userDict["user"] = context["user"].id  
    if "categoria" in request.POST: 
     newPost = request.POST.copy() 
     newPost.update(userDict) 
     form = PostForm(newPost,request.FILES) 
     print("postform POST: ",newPost, " File ",request.FILES) 
     if form.is_valid(): 
      print("valid") 
      try: 
       form.save() 
       print("saved") 
       return HttpResponseRedirect(reverse_lazy('accounts:profile')) 
      except IntegrityError as e: 
       print("Integrity Error") 
       exception=e    
     else: 
      print("PostForm error") 
      print(form.errors) 

    form.non_field_errors=form.errors 
    if exception is not None: 
     form.non_field_errors.update(exception) 
    context['form']=form 

posts = Postagem.objects.get_queryset().order_by('id') 
paginator = Paginator(posts, 12) 
page = request.GET.get('page') 
context["areas"] = Area.objects.all() 
try: 
    posts = paginator.page(page) 
except PageNotAnInteger: 
    # If page is not an integer, deliver first page. 
    posts = paginator.page(1) 
except EmptyPage: 
    # If page is out of range (e.g. 9999), deliver last page of results. 
    posts = paginator.page(paginator.num_pages) 

context["posts"]=posts 

return render(
    request, 
    'accounts/profile.html', 
    context 
) 

そして最後テンプレートで

：の

{% for post in posts %} 
     {% if forloop.counter0|divisibleby:4 or forloop.counter0 == 0 %}  
     <div id="grid-profile" class="row grid"> 
      <div class="col-md-1"></div> 
     {% endif %} 

      {% ifnotequal post.categoria "Imagem"%} 
      <iframe id=post{{forloop.counter}} width="420" height="315" 
       src={{post.post.url}}> 
      </iframe> 
      {% else %} 
      <div class="col-md-2"> 
       <button type="button" id="modal1trigger" data-toggle="modal" data-target="#modal1"><img class="img-responsive" src={{post.post.url}}></img></button> 
      </div> 
      {% endifnotequal %} 

     {% if forloop.counter|divisibleby:4 or forloop.counter == posts|length %} 
      <div class="col-md-1"></div> 
     </div> 
     {% endif %} 
     {% endfor %} 
     <div class="pagination"> 
      <span class="step-links"> 
       {% if posts.has_previous %} 
        <a href="?page={{ posts.previous_page_number }}">previous</a> 
       {% endif %} 

       <span class="current"> 
        Page {{ posts.number }} of {{ posts.paginator.num_pages }}. 
       </span> 

       {% if posts.has_next %} 
        <a href="?page={{ posts.next_page_number }}">next</a> 
       {% endif %} 
      </span> 
     </div> 

は、私はカットし、いくつかの私は、次のモデルを持っていますテンプレート...とにかく、私はできるようになりたいすべての種類の投稿を追加します。歌、ビデオ、画像、文書などが含まれています。投稿が追加されています。しかし、私は繰り返しエラーが発生していると私は理由を知らない。それは非常に危険かもしれませんので、私はそれを調べ始めましたが、受け入れられる答えを見つけるのは幸運でした。 エラーは、曲やビデオを取得しようとしたときにのみ発生します。

ちょっと、エラーのみの場合 htmlにiframeタグがある場合は！

Answer 1

それが表示されているPythonのエラー：

クロームでエラーのようです。それは私には来なかった。なぜなら私はオペラを使っていたからだが、オペラはクロムも使う。 Internet Explorerでは、エラーは表示されませんでした。

https://code.djangoproject.com/ticket/21227#no1

これは、問題は、このself.environとself.statusは、特に私のプロジェクトからのものではないですバグトラッカー

Answer 2

最初のエラー self.environ['SERVER_PROTOCOL'].upper()は、self.environ ['SERVER_PROTOCOL']がNoneであり、None.upper（）を実行できないため、失敗しています。文字列の.upper（）私は意識している）。

2番目のエラー self.status.split(' ',1)[0], self.bytes_sent AttributeError: 'NoneType' object has no attribute 'split' あなたはself.statusので、これは失敗であるNoneです、あなたはNone.split（）を行うことができない、再びこれは文字列でなければなりません。

したがって、これらのクラスに必要な値の一部が初期化されていないか、または渡されていないようです。

Django.coreとWSGIrefに問題があるようですので、設定が正しくないか、インストールしたバージョンに問題がありますか？

実行中のDjangoのバージョンは？ ./manage.py runserverからサーバーを実行していますか？

は、[更新2017年9月28日]

あり、私が変更した物事のカップルが、だ私はそれを渡す前に、新しい辞書にrequest.POSTをコピーしていないよと開始するには、これは可能性が投稿を処理しようとしたときに値の一部が消えてしまう原因。

コピーしたPOSTに注入するのではなく、ユーザーをkwargとしてフォームに渡しています。

ほとんど私はちょっと読みやすくするためにいくつかのコードを更新しましたが、それがどうなるか見てみましょう。
