Я хочу обновить его после регистрации изображения, но изображение не появляется всякий раз, когда я его обновляю.

Я делаю функцию обзора, но если я регистрирую картинку в обзоре и обновляю его, картинка не отображается должным образом. Тем не менее, остальное содержимое рецензии обновляется нормально. Я не знаю, почему только картинка не отображается должным образом.

здесь view.py:

def update(request, id): 
    review = Post.objects.get(id=id)
    category = review.postType
    placeId = review.placeId
    
    if category == 'cafe':
        place = Cafe.objects.get(id=placeId)
    elif category == 'accomo':
        place = Accomodation.objects.get(id=placeId)
    else:
        place = Place.objects.get(id=placeId)

    if request.method == "POST":
        postGood = request.POST["postGood"]
        postBad = request.POST["postBad"]
        try:
            postImage = request.FILES['postImage']
        except:
            postImage='NULL'
        ranking = request.POST["ranking"]

        Post.objects.filter(id=id).update(postGood=postGood,postBad=postBad,postImage=postImage,ranking=ranking)


        posts = Post.objects.filter(Q(postType=category)&Q(placeId=placeId))
        total = 0
        len_posts= len(posts)
        for p in posts:
            total += p.ranking
        place.star = total/len_posts
        place.save()
        return redirect(f"/reviewDetail/{review.id}")

    placeName = place.name
    location = place.location

    context = {"review":review, "placeName":placeName}
    return render(request, "reviewUpdate.html", context=context)

здесь update.html:

def update(request, id): 
    review = Post.objects.get(id=id)
    category = review.postType
    placeId = review.placeId
    
    if category == 'cafe':
        place = Cafe.objects.get(id=placeId)
    elif category == 'accomo':
        place = Accomodation.objects.get(id=placeId)
    else:
        place = Place.objects.get(id=placeId)

    if request.method == "POST":
        postGood = request.POST["postGood"]
        postBad = request.POST["postBad"]
        try:
            postImage = request.FILES['postImage']
        except:
            postImage='NULL'
        ranking = request.POST["ranking"]

        Post.objects.filter(id=id).update(postGood=postGood,postBad=postBad,postImage=postImage,ranking=ranking)


        posts = Post.objects.filter(Q(postType=category)&Q(placeId=placeId))
        total = 0
        len_posts= len(posts)
        for p in posts:
            total += p.ranking
        place.star = total/len_posts
        place.save()
        return redirect(f"/reviewDetail/{review.id}")

    placeName = place.name
    location = place.location

    context = {"review":review, "placeName":placeName}
    return render(request, "reviewUpdate.html", context=context)

Create работает хорошо, но на всякий случай... (чтобы исправить обновление) вот view.py:

def create(request,category,category_id):
    current_user = request.user
    me = User.objects.get(username=current_user) 

    if category == 'cafe':
        place = Cafe.objects.get(id=category_id)
    elif category == 'accomo':
        place = Accomodation.objects.get(id=category_id)
    else:
        place = Place.objects.get(id=category_id)

    placeName = place.name
    location=place.location

    if request.method == "POST":
        postGood = request.POST["postGood"]
        postBad = request.POST["postBad"]
        try:
            postImage = request.FILES['postImage']
        except:
            postImage='NULL'
        ranking = request.POST["ranking"]
        new_post=Post.objects.create(user=me,postType=category,postImage=postImage,postGood=postGood,postBad=postBad,ranking=ranking, placeId=category_id)

        posts = Post.objects.filter(Q(postType=category)&Q(placeId=category_id))
        total = 0
        len_posts= len(posts)
        for p in posts:
            total += p.ranking
        place.star = total/len_posts
        place.save()

        return redirect(f"/reviewDetail/{new_post.id}")
    else:
        return render(request, 'reviewWrite.html', {'placeName':placeName,'location':location, 'category':category, 'category_id':category_id})

здесь create.html:

<form action="/create/{{category}}/{{category_id}}" method="POST" enctype="multipart/form-data">
      <div class="post_container">
        {% csrf_token %}
        <div class="post_review">
          <p>
            <span class="review_span">다녀온 곳 </span> {{placeName}}
          </p>
          <input type="file" name="postImage" />
          <br>

вот модель Post:

class Post(models.Model):
    postType = models.CharField(max_length=100, null=True)
    postImage= models.ImageField(blank=True, null=True, default="NULL", upload_to='posts/%Y%m%d', verbose_name="사진")
    postGood= models.TextField(null=True)
    postBad= models.TextField(null=True)
    ranking= models.FloatField(null=True, blank=True)
    user = models.ForeignKey(User, related_name='user_post', on_delete=models.CASCADE)
    placeId = models.IntegerField(null=True)


here is url.py:
  path('create/<str:category>/<int:category_id>', views.create, name='create')
  path('delete/<int:id>', views.delete, name="delete")
  path('update/<int:id>', views.update, name="update")
