int（）引数はdjangoの 'SimpleLazyObject'ではなく、文字列または数字でなければなりません

Question

私はこの問題をSelfieモデルのpkにキャッチしていますが、コメントを保存しようとしていますが、 views.pyにCREATECOMMENTクラスであり、みんなは私がmodels.py views.py

class SelfieDetail(DetailView): 
    template_name = "SelfieDetail.html" 
    model = Selfie 

    def get_context_data(self, **kwargs): 
     context = super(SelfieDetail, self).get_context_data(**kwargs) 
     context['form'] = CommentForm 
     if self.request.POST: 
      context['form'] = CommentForm(self.request.POST) 
     else: 
      context['form'] = CommentForm() 
     return context 

class CreateComment(FormView): 
    form_class = CommentForm 
    success_url = '../login' 
    template_name = "SelfieDetail.html" 

    def get_form_kwargs(self): 
     form_kwargs = super(CreateComment, self).get_form_kwargs() 
     if 'pk' in self.kwargs: 
      form_kwargs['instance'] = models.Selfie.objects.get(pk=int(self.kwargs['pk'])) 
     return form_kwargs 

    def form_valid(self, form, *args, **kwargs): 
     context = self.get_context_data() 
     form = context['form'] 
     obj = form.save(commit=False) 
     obj.comment_user_id = self.request.user 
     #obj.post_comment_id = kwargs={'pk': Selfie.pk} .... self.request.POST.get('comment') 
     obj.post_comment_id = self.request.GET.get('post_comment_id') 
     obj.save() 
     return redirect('/login') 

で

class Selfie(models.Model): 
    selfie_title = models.CharField(max_length=50) 
    selfie_description = models.TextField(null=True, blank=True) 
    selfie_image = models.ImageField(upload_to="images/", 
     width_field="selfie_width", 
     height_field="selfie_height", 
     ) 
    selfie_height = models.IntegerField(default=0) 
    selfie_width = models.IntegerField(default=0) 
    selfie_favorite = models.BooleanField() 
    selfie_user = models.ForeignKey("auth.User") 
    selfie_timestamp = models.DateTimeField(auto_now=True) 

    def __unicode__(self): 
     return unicode(self.selfie_title) 

    def __str__(self): 
     return self.selfie_title 

class Comment(models.Model): 
    comment_user = models.ForeignKey("auth.User") 
    body_comment = models.TextField() 
    timestamp_comment = models.DateTimeField(auto_now=True) 
    post_comment = models.ForeignKey("Selfie") 

    def __unicode__(self): 
     return unicode(self.body_comment[:20]) 

    def __str__(self): 
     return self.body_comment[:20] 

に

手を必要としてください。それは整数を期待するので

テンプレート

<form method="POST" action="{% url 'createComment' %}"> 
{% csrf_token %} 
{{ form.as_p }} 
<button type="submit" class="btn btn-lg">(Comentar)</button> 
</form>

Answer 1

あなたはcomment_user_idからuserを割り当てることはできません。次のいずれかが動作します：

obj.comment_user_id = self.request.user.id 

obj.comment_user = self.request.user
