在views.py中

class Selfie(models.Model):
    selfie_title = models.CharField(max_length=50)
    selfie_description = models.TextField(null=True, blank=True)

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

    def __str__(self):

模板

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:

        obj.post_comment_id = self.request.GET.get( 'post_comment_id' )
        obj.save()
        return redirect('/login')

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

您无法将user分配给comment_user_id，因为它需要一个整数。以下任何一种都可以使用：

obj.comment_user_id = self.request.user.id

obj.comment_user = self.request.user
