Question

我正在尝试通过ModelForm在CreateView中创建一个新对象。我想让'player'实例拥有一个图像。但上传的图像不会存储到'player_image'目录或写入数据库。

这些是我的文件：

models.py：

class Player(models.Model):
    last_name = models.CharField(max_length=255, verbose_name=_("Last Name"))
    first_name = models.CharField(max_length=255, verbose_name=_("First Name"))
    secret_name = models.CharField(max_length=255, verbose_name=_("Secret Key"), unique=True)
    image = ImageField(upload_to='player_images/', verbose_name=_("Image"), null=True, blank=True)

player_form.py

class PlayerForm(forms.ModelForm):
    last_name = forms.CharField(required=True, label=_("Last Name"))
    first_name = forms.CharField(required=True, label=_("First Name"))

    class Meta:
        model = Player
        fields = ['first_name', 'last_name', 'image']

player_add_view.py

class PlayerAddView(LoginRequiredMixin, CreateView):
    form_class = PlayerForm
    template_name = "project/player_add_view.html"
    model = Player

def form_valid(self, form):
    player = form.save(commit=False)

    # I do other stuff here
    player.save()

    return HttpResponseRedirect(reverse('home'))

在views.py或enctype =＆＃34; multipart / form-data＆＃34;中可能会有一些缺失，如request.FILES。在表格中。

请看这里：https://docs.djangoproject.com/en/1.8/topics/http/file-uploads/

转到您的模板并添加：

 <form method="post" enctype="multipart/form-data">

我不知道为什么它不能正常工作，但在我的项目中，哪个有效，我从后期请求中获取图像是这样的：

profile_form = ProfileForm(data=request.POST)
if profile_form.is_valid():
    if 'picture' in request.FILES:
        current_user.image = request.FILES['image']

Django创建查看图像上传
