django - 如何在 Django 中修复此操作错误？

Question

我在views.py 中创建了一个评论视图，供用户通过表单编写和提交评论。评论将显示在显示有关电影的信息的同一模板上。

当我尝试进入其中一部电影时，出现此错误：

/myapp2/2/ 处的 OperationalError 没有这样的列：myapp2_comentario.pelicula_id

视图.py

def detallesPelicula(request, pelicula_id):
peliculas = get_list_or_404(Pelicula.objects.order_by('titulo'))
pelicula = get_object_or_404(Pelicula, pk=pelicula_id)
actor = get_list_or_404(Actor.objects)

comentarios = Comentario.objects.filter(pelicula=pelicula).order_by('fecha')
comment_form = CommentForm(request.POST or None)

if request.method == 'POST':
    if comment_form.is_valid():
        comentario = comment_form.save(commit=False)
        comentario.usuario = request.user
        comentario.save()

        return HttpResponseRedirect(pelicula.get_absolute_url())


context = {'pelicula': pelicula, 'peliculas': peliculas, 'comentarios':comentarios,'comment_form':comment_form}
return render(request, 'detallesPelicula.html', context)

我的模型.py

class Comentario(models.Model):
usuario = models.ForeignKey(User,on_delete=models.CASCADE)
pelicula =models.ForeignKey(Pelicula, on_delete=models.CASCADE)
fecha = models.DateTimeField(auto_now_add=True,null=True,blank=True)
texto = models.TextField(max_length=2000, default="")

def __str__(self):
    return self.usuario.nickname

表格.py

class CommentForm(forms.ModelForm):
class Meta:
    model = Comentario
    fields = ['texto']
