Question

我跟随Add image/avatar to users in django提示，让用户上传他们的个人资料照片，并在用户登录时显示用户的个人资料照片。

Adding profile picture to django user

但出于某种原因，它出现了一个错误：“禁止创建没有'fields'属性或'exclude'属性的ModelForm;表单UserProfileForm需要更新。”

无论如何我可以直接修改django.contrib.auth.models的用户模型，这样我只能添加个人资料图片并将其显示在index.html上吗？

没有关于此个人资料图片系统的大量信息。

自从我开始学习django和python以来，这只是几天。

任何人都可以用例子来解释，我怎么能做到这一点？

感谢。

（这是实现上述提示的forms.py）

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth import authenticate, get_user_model, login, logout

class UserSignupForm(forms.ModelForm):
    email = forms.EmailField(label='Confirm Email')
    password = forms.CharField(widget=forms.PasswordInput)
    class Meta:
        model = User
        fields = [
            'username',
            'email',
            'password'
        ]
    def clean_email(self):
        email = self.cleaned_data.get('email')
        email_qs = User.objects.filter(email=email)
        if email_qs.exists():
            raise forms.ValidationError("This email has already been registered")
        return email



from django.core.files.images import get_image_dimensions
from .models import UserProfile


class UserProfileForm(forms.ModelForm):
    class Meta:
        model = UserProfile

    def clean_avatar(self):
        avatar = self.cleaned_data['avatar']

        try:
            w, h = get_image_dimensions(avatar)

            #validate dimensions
            max_width = max_height = 100
            if w > max_width or h > max_height:
                raise forms.ValidationError(
                    u'Please use an image that is '
                     '%s x %s pixels or smaller.' % (max_width, max_height))

            #validate content type
            main, sub = avatar.content_type.split('/')
            if not (main == 'image' and sub in ['jpeg', 'pjpeg', 'gif', 'png']):
                raise forms.ValidationError(u'Please use a JPEG, '
                    'GIF or PNG image.')

            #validate file size
            if len(avatar) > (20 * 1024):
                raise forms.ValidationError(
                    u'Avatar file size may not exceed 20k.')

        except AttributeError:
            """
            Handles case when we are updating the user profile
            and do not supply a new avatar
            """
            pass

        return avatar

实施例： models.py：

class YouModel(models.Model):
    .............You field ................
    user_avatar = models.ImageField((upload_to="You/media/uploads", blank=True) # You need to configure media in settings.py
    ........... You fields ..............

class YouModelForm(ModelForm)
    class Meta:
        model = YouModel
        fields = ['user_avatar']

views.py：

来自.models导入YouModel，YouModelForm

def youfunc(request):
    youtemplate = YouModelForm()
    if request.method == POST:
        youform = YouModelForm(request.POST, request.FILES)
        if youform.is_valid():
           youform.save()
           return HttpResponseRedirect('http://www.You.url') # or other
    youquery = .objects.order_by('user_avatar').last()
    return render(request, "YouProject/YouHtml.html", {'youtemplate': youtemplate, 'youquery': youquery})

我累了写。您需要配置django并从用户写入第一个文件上传。您可以访问我的网站并查看和决定 - 这是您想要的吗？我的网站http://www.webmamoffice.org/en并转到UperVote或http://www.webmamoffice.org/en/upervote
