为什么我的“ if project_form.is_valid（）和p_formset.is_valid（）”不起作用？

因此，我一直在尝试在我的网站上实施一项功能，以便能够在其中发布多张图片。我不确定为什么同时对project_forms.is_valid（）和p_formset.is_valid（）都执行if语句，但我的代码无法正常工作。但是，如果只是其中之一，它们就可以正常工作。

我没有出现任何错误，只是它没有按预期执行。没有图像或帖子进入我的数据库。

我实现多图片上传的方式是为帖子和多图片上传创建单独的表格，但使用外键链接。

这是我的代码：

views.py

def create_projects(request):
    # Special case if the request method is not POST

    project_form = ProjectsForm(request.POST, request.FILES)
    p_formset = P_ImageForm(request.POST, request.FILES)

        # Checks if the form is valid before save
    if project_form.is_valid() and p_formset.is_valid():
        instance = project_form.save(commit=False)
        instance.user = request.user
        instance.save()
        p_photos = p_formset.save(commit=False)
        p_photos.save()

        data = {'is_valid': True, 'name': p_photos.p_file.name, 'url': p_photos.p_file.url}

        return JsonResponse(data)

    else:

        data = {'is_valid': False}

    context = { 
    'project_form': project_form,
    'p_formset': p_formset,
    }
    return render(request, 'projects/forms.html', context)

    img_height = models.PositiveIntegerField(default=600)
    img_width = models.PositiveIntegerField(default=300)

    def __str__(self):
        return self.title

    def save(self, *args, **kwargs):
        # Generates a random string 
        unique_string = get_random_string(length=32)

        # Combines title and unique string to slugify
        slugtext = self.title + "-" + "unique_id=-" + unique_string
        self.slug = slugify(slugtext)

        return super(Projects, self).save(*args, **kwargs)

def get_p_image_filename(instance, filename):
    title = instance.p_post.title
    slug_title = slugify(title)
    return "post_images/%s-%s" % (slug_slug, filename)

class P_Images(models.Model):
    p_file = models.ImageField(upload_to='images/', blank=None)
    p_uploaded_at = models.DateTimeField(auto_now_add=True, auto_now=False)
    #p_post = models.ForeignKey(Projects, on_delete=models.CASCADE, default=DEFAULT_IMAGE_ID)

由于一个单独的问题，外键变量已被注释掉。我正在尝试通过解决此问题来修复它，以便可以将其保存到我的数据库中。
