使用FBV对多个图像进行后期创建

大家好,我是Django的新手,头发拉扯了,快秃顶了。谁能帮我一下吗。

我正在尝试将多个图像添加到我的帖子中,但我遇到了问题。我有两个模型。一个帖子模型和一个图片模型。我的帖子模型已经有1个imagefield。然后我有另一个相关的模型,它允许多个图像。下面是我的模型的样子

class Post(models.Model):
    user = models.ForeignKey(User, related_name='posts')
    title = models.CharField(max_length=250, unique=True)  
    slug = models.SlugField(allow_unicode=True, unique=True)  
    message = models.TextField()  
    post_image = models.ImageField()

class Image (models.Model): #(Images)
    post = models.ForeignKey(Post, on_delete=models.CASCADE)
    image = models.ImageField(upload_to='images/', blank=True, null=True)
    image_title = models.CharField(max_length=100)
    image_description = models.CharField(max_length=250)

    def __str__(self):
        return self.post.title + " Image"

下面是我的观点。当窗体加载时。它有多个图像字段。只是在我的帖子创建时没有保存这些图片。我收到一篇帖子,完全忽略了表单集和多个图像。它仅显示后模型方面和后模型的1个图像。即使在管理中也没有多个图像。

有人能告诉我代码中的错误是什么吗?

视图。py第一次尝试

@login_required
def post_create(request):
    ImageFormset = modelformset_factory(Image, fields=('image', 'image_title', 'image_description'), extra=7)
    if request.method == 'POST':
        form = PostForm(request.POST, request.FILES)
        formset = ImageFormset(request.POST or None, request.FILES or None)
        if form.is_valid() and formset.is_valid():
            post = form.save(commit=False)
            post.user = request.user
            post.save() ## It seems as if my code just plays till here and then disconnects
            for f in formset:
                try:
                    photo = Image(post=post, image=f.cleaned_data['image', 'image_title', 'image_description'])
                    photo.save()
                    return redirect('posts:single', username=request.user.username, slug=post.slug)
                except Exception as e:
                    break
    else: ## This part works too as it shows the correct empty form
        form = PostForm()
        formset = ImageFormset(queryset=Image.objects.none())
    context = {'form': form, 'formset': formset}
    return render(request, 'posts/post_form.html', context)

下面是我的表格。py公司

class PostForm(forms.ModelForm):
    class Meta:
        model = Post
        fields = ('title', 'message', 'post_image' )

更改了user3054319建议的视图,请参见下文。它工作正常,但在图像文件夹中仅保存1个图像。一切正常吗我的缩进

视图。py第二次尝试

@login_required
def post_create(request):
    ImageFormset = modelformset_factory(Prep, fields=('image', 'image_title', 'image_description'), extra=7)
    if request.method == 'POST':
        form = PostForm(request.POST, request.FILES)
        formset = ImageFormset(request.POST or None, request.FILES or None)
        if form.is_valid() and formset.is_valid():
            post = form.save(commit=False)
            post.user = request.user
            post.save()
            for f in formset:
                try:
                    photo = Prep(post=post, image=f.cleaned_data['image'], image_title=f.cleaned_data['image_title'],
                                 image_description=f.cleaned_data'image_description'])
                    photo.save()
                    return redirect('posts:single', username=request.user.username, slug=post.slug)
                except Exception as e:
                    break 

然后,我尝试删除try和except语句,并在循环外部获取重定向 它保存所有7幅图像 但最后给出了一个错误(见下面的错误图片)

视图。py第三次尝试

@login_required
def post_create(request):
    ImageFormset = modelformset_factory(Prep, fields=('image', 'image_title', 'image_description'), extra=7)
    if request.method == 'POST':
        form = PostForm(request.POST, request.FILES)
        formset = ImageFormset(request.POST or None, request.FILES or None)
        if form.is_valid() and formset.is_valid():
            post = form.save(commit=False)
            post.user = request.user
            post.save()
            for f in formset:
                    photo = Prep(post=post, image=f.cleaned_data['image'], image_title=f.cleaned_data['image_title'], image_description=f.cleaned_data['image_description'])                                 
                    photo.save()
                return redirect('posts:single', username=request.user.username, slug=post.slug)

下面的错误图像 如果这可以通过CBV实现,我可以添加一段我跳舞的视频,就像我中了彩票一样。但我不会太贪心,即使解决这个问题也能帮我省点麻烦
