Django - 发布表单后图像不会上传

Question

更改用户名或电子邮件可以，但不能更改个人资料图片。

我在“INSTALLED_APPS”中添加了我的个人资料应用程序，设置 MEDIA_ROOT 和 MEDIA_URL 并设置 urlspatterns ：

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'home.apps.HomeConfig',

    'inscription.apps.InscriptionConfig',

    'profile.apps.ProfilConfig',

]

    

[...]

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

MEDIA_URL = '/media/'

[...]

urlpatterns = [

    path('profile/', p.profile, name='profile'),

] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

我将用户链接到其个人资料，设置默认图像models.py并在中注册模型admin.py

from django.db import models

from django.contrib.auth.models import User

    

class Profile(models.Model):

    user = models.OneToOneField(User, on_delete=models.CASCADE)

    image = models.ImageField(default='default.png', upload_to='profile_image')

    

    def __str__(self):

        return f"{self.user.username}'s Profile"

[...]

from django.contrib import admin

from .models import Profil

    

admin.site.register(Profil)

然后我在 forms.py 中创建了配置文件修改表单：

from django import forms

from django.contrib.auth.models import User

from django.contrib.auth.forms import UserCreationForm

from .models import Profile

    

class ChangeUserForm(forms.ModelForm):

    username = forms.CharField(

        label = 'Username',

        min_length = 4,

        max_length = 150,

            initial=User.username,

        )

        email = forms.EmailField(

            label = 'Email',

            min_length = 4,

            max_length = 150,

        )

    

class Meta:

    model = User

    fields = ['username', 'email']

    

class ChangeProfileForm(forms.ModelForm):

    image = forms.FileField(

        label = 'Profile form'

    )

class Meta:

    model = Profile

    fields = ['image']

当您使用 HTML 形式的文件时，应该添加 enctype。<form&nbsp;method="post"&nbsp;enctype="multipart/form-data">
