Python Django模型中未上载图像

我能够更新每个用户的个人资料图片的图像。 但不是通过代码。虽然它没有给我任何错误

u_form=用于更改用户名。 p_form=用于更改其配置文件中的图片

注：纵断面与纵断面模型有一对一关系

settings.py文件部分：

STATIC_URL = '/static/'
STATICFILES_DIRS = (os.path.join(BASE_DIR, 'static'),)
MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')
MEDIA_URL = '/media/'

models.py对于剖面模型：

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    image = models.ImageField(default='default.jpeg', upload_to='profile_pics')
    status = models.TextField(max_length='200')

    def __str__(self):
        return self.user.username

forms.py用于相同的：

class ProfileUpdate(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ['image',]

<form action="{% url 'update_profile' %}" method="POST" enctype="multipart/form-data">
    {% csrf_token %}
    {{ u_form }}
    {{ p_form }}
    <button type="submit">submit</button>
</form>

Mainviews.py文件：

.
.
from django.shortcuts import render, redirect
from django.contrib.auth.forms import  UserCreationForm as uc
from django.contrib.auth.forms import AuthenticationForm as af
.
.

@login_required(login_url='/login')
def update_profile(request):
    user = request.user
    if request.method == 'POST':
        u_form = UserUpdate(request.POST, instance=user)
        p_form = ProfileUpdate(request.POST, request.FILES, instance=user)
        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, 'The profile has been updated.')
            return redirect('/profile')
    else:
        #instance: to get pre-filled data of user
        u_form = UserUpdate(instance=user)
        p_form = ProfileUpdate(instance=user.profile)
        context = {
            'u_form': u_form,
            'p_form': p_form
        }
        return render(request, 'update_profile.html', context)

HTML表单“update_profile.HTML”：

class ProfileUpdate(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ['image',]

<form action="{% url 'update_profile' %}" method="POST" enctype="multipart/form-data">
    {% csrf_token %}
    {{ u_form }}
    {{ p_form }}
    <button type="submit">submit</button>
</form>

{%csrf_令牌%}
{{u_形式}
{{p_form}}
提交

试试这个：

p_form = ProfileUpdate(request.POST, request.FILES, instance=user.profile)

您必须传递配置文件实例，而不是用户实例p\u form=ProfileUpdate（request.POST，request.FILES，instance=Profile\u instance）
