无法上传Django中的图像

Question

我有一个个人资料页面,我希望允许用户上传个人资料图片.我可以编辑所有文本,但无法上传图像.如果我通过管理员添加图像,但不通过网站上的用户个人资料页面,它可以工作.请注意,通过管理员创建时 - 它正确上传到我在媒体文件夹中指定的目录(profile_image).我在模板页面上创建了一些错误处理,但生成的错误是:"'image'属性没有与之关联的文件." 以下是我的代码:

models.py

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    first_name = models.CharField(default='',max_length=100 )
    last_name = models.CharField(default='',max_length=100)
    email = models.CharField(max_length=100, default='')
    date_birth = models.DateField(default=datetime.datetime.now())
    bio = models.TextField(default='')
    image = models.ImageField(upload_to='profile_image', blank=True)


def create_profile(sender, **kwargs):
    if kwargs['created']:
        user_profile = UserProfile.objects.create(user=kwargs['instance'])

post_save.connect(create_profile, sender=User)

views.py

@login_required
def edit_profile(request):
    profile = get_object_or_404(models.UserProfile)
    if request.method == 'POST':
        form = forms.EditProfileForm(data=request.POST, instance=profile)

        if form.is_valid():
            form.save()
            return redirect('/accounts/profile')
    else:
        form = forms.EditProfileForm(instance=profile)
        args = {'form':form}
        return render(request, 'accounts/edit_profile.html', args)

forms.py

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserChangeForm

from . import models


class UserProfileForm(forms.ModelForm):
    class Meta:
        model = models.UserProfile
        fields = [
            'first_name',
            'last_name',
            'email',
            'date_birth',
            'bio',
            'image',
        ]


class EditProfileForm(UserProfileForm):
    model = models.UserProfile
    fields = [
        'first_name',
        'last_name',
        'email',
        'date_birth',
        'bio',
        'image',
    ]

settings.py

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'accounts/media')

edit_profile.html

{% extends "layout.html" %}

{% block title %}User Profile | {{ user }}{{ super }}{% endblock %}

{% block body %}
<h1>My Profile</h1>

<form action="" method="POST" enctype="multipart/form-data">{% csrf_token %}
{{ form.as_p}}
    <button type="submit">Save</button>
</form>

{% endblock %}

Answer 1

该文件进来request.FILES,而不是request.POST.在视图中执行以下操作:

form = forms.EditProfileForm(data=request.POST, files=request.FILES, instance=profile)

请参阅文件上传文档:

处理此表单的视图将接收文件数据request.FILES,该文件数据是包含表单中每个FileField(ImageField或其他FileField subclass)键的字典.
