Django上的实例不工作，图片字段除外

您知道为什么Django实例在我下面的代码中不能正常工作吗？这个想法是允许用户编辑他们的文章（在我的代码中称为seed），这样做对他们访问当前文章中的数据更方便。但出于某种原因，表单保持为空，图片字段除外，无论发生什么情况。所以我想知道我的代码是否有部分取消了这个实例。谢谢你的帮助

views.py

def seed_edit(request, slug):
    to_edit_seed = Seed.objects.get(slug=slug)
    if to_edit_seed.user.id != request.user.id:
        return render(request, 'dist/inside/knowledge/404_not_allowed.html')
    else:
        if request.method == 'POST':
            seed_form_edit = SeedForm(request.POST, request.FILES, instance=to_edit_seed)
            seed_vc_edit = SeedFormVC(request.POST)
            if seed_form_edit.is_valid() and seed_vc_edit.is_valid():
                seed = seed_form_edit.save(commit=False)
                seed.save()
                seed_form_edit.save_m2m()
                if Value_Chain_Seed.objects.filter(seed_id=to_edit_seed.id).exists():
                    f = Value_Chain_Seed.objects.filter(seed_id=to_edit_seed.id)
                    f.delete()
                    seed_vc_edit.instance.seed = to_edit_seed
                    seed_vc_edit.save()
                else:
                    seed_vc_edit.instance.seed = to_edit_seed
                    seed_vc_edit.save()
                messages.success(request,'Your seed was successfully updated!')
                return redirect(reverse(("knowledge:one_seed"),args=[to_edit_seed.slug]))
            else:
                seed_form_edit = SeedForm(request.POST, request.FILES, instance=to_edit_seed)
                seed_vc_edit = SeedFormVC(request.POST)

            seed_vc_edit = SeedFormVC(request.POST)

        return render(request, 'dist/inside/knowledge/seed/edit_seed.html', {
            'to_edit_seed': to_edit_seed,
            'seed_form_edit': seed_form_edit,
            'seed_vc_edit': seed_vc_edit,
    })

好吧，这么久之后，我终于明白了哪里出了问题，在“else”部分，我不应该添加request.Post或request.File，因为这样会停止加载文章。。。。所以是的
