来自 ModelForm 的图像未保存

Question

我在 wagtail 中有一个 Pgae 模型，它持有一个 ImageField：

from django.conf import settings
from wagtail.users.models import upload_avatar_to
from django.utils.translation import gettext_lazy as _

class ProfilePage(Page):
    avatar = models.ImageField(
        # Also updated from user.wagtail_userprofile.avatar
        verbose_name=_("profile picture"),
        upload_to=upload_avatar_to,
        blank=True,
    )
    intro = RichTextField(
        blank=True,
        null=True,
        verbose_name=_("Personal introduction"),
        help_text=_("maximum number of characters: 80 characters"),
        max_length=80,
    )
    school = models.CharField(
        verbose_name=_("School name"), max_length=100, blank=True, null=True
    )
    school_details = models.CharField(
        blank=True,
        null=True,
        verbose_name=_("School details"),
        help_text=_("example: Faculty of Medicine"),
        max_length=100,
    )
    location = models.CharField(
        verbose_name=_("Location"),
        max_length=50,
        blank=True,
        null=True,
        help_text=_("example: Osaka"),
    )
    user = models.ForeignKey(
        settings.AUTH_USER_MODEL, on_delete=models.PROTECT, verbose_name=_("User")
    )

我需要创建一个模型表单，因为我在渲染自定义模板以在注册后设置配置文件：

from django import forms
from django.forms import ModelForm

class ProfilePageDetailsForm(ModelForm):
    intro = forms.CharField(
        required=False,
        widget=forms.Textarea,
        label=_("Personal introduction"),
        help_text=_("maximum number of characters: 80 characters"),
        max_length=80,
    )

    class Meta:
        model = ProfilePage
        fields = [
            "avatar",
            "title",
            "school",
            "location",
            "intro",
        ]

我的view.py:

def profile_details(request: HttpRequest, pk: int = None) -> HttpResponse:
    user = cast("User", request.user)
    profile = ProfilePage.objects.get(pk=pk)
    form = ProfilePageDetailsForm(instance=profile)
    if request.method == "POST":
        form = ProfilePageDetailsForm(request.POST, instance=profile)
        if form.is_valid():
            form.save()
            return redirect("wagtailadmin_home")

    context = {
        "user": user,
        "form": form,
    }

    return render(request, "account/profile_details.html", context)

我的模板profile_details.html

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

    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" class="button" value="{% trans 'submit' %}">
</form>

点击提交并填写包括头像字段在内的所有字段后，我被成功重定向到 wagtail 管理页面但是当我查看个人资料页面时，头像图像不存在我尝试调试，但在此过程中没有发现任何错误非常欢迎任何帮助或建议非常感谢

当您 re-bind 表单出现在您的视图中时，您需要传递 request.FILES 和 request.POST - 请参阅 https://docs.djangoproject.com/en/3.1/topics/http/file-uploads/
