问题描述

我正在制作一个django webapp，用户可以在其中上传个人资料图像。我还使用默认的 USERCHANGEFORM 创建了一个 EDIT PROFILE 页面。但是问题是，我无法从该表单更新个人资料图片。我可以删除它，但不能上传新的吗？需要帮助。
这是我的用户创建表格：

I am making a django webapp where users can upload profile image. I have also created an EDIT PROFILE page by using the default USERCHANGEFORM. But the problem is, that I cannot update the profile picture from that form. I can delete it but not upload new one? Help needed. This is my USER CREATION FORM:

class SignUpForm(UserCreationForm):

    photo               = forms.ImageField(required=False)
    bio                 = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Enter your bio'}))
    designation         = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Enter your designation'}))
    university          = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Enter your university'}))

    company_name        = forms.CharField(widget=forms.TextInput(attrs={'placeholder': "Enter your company's name"}))
    grad_year           = forms.IntegerField(widget=forms.TextInput(attrs={'placeholder': 'What year did you graduate in?'}))
    phone               = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Enter your phone number'}))
    address             = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Enter your present address'}))
    city                = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Enter your city'}))
    company_category    = forms.CharField(widget=forms.TextInput(attrs={'placeholder':  "Enter your company's category"}))
    company_desc        = forms.CharField(widget=forms.TextInput(attrs={'placeholder': "Enter your company's description"}))
    company_site        = forms.CharField()
    no_employees        = forms.IntegerField(widget=forms.TextInput(attrs={'placeholder': 'Enter no. of employees in your company'}))
    technologies        = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'What technologies are you interested in?'}))
    markets             = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'What markets are you interested in?'}))
    linkedin            = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Enter your Linked In profile'}))

    def __init__(self, *args, **kwargs):
        super(UserCreationForm, self).__init__(*args, **kwargs)
        del self.fields['password2']

        for fieldname in ['password1']:
            self.fields[fieldname].help_text = None

        self.fields['password1'].widget.attrs.update({'placeholder': 'Enter your password'})
        self.fields['first_name'].widget.attrs.update({'placeholder': 'Enter your first name'})
        self.fields['last_name'].widget.attrs.update({'placeholder': 'Enter your last name'})
        self.fields['company_site'].widget.attrs.update({'placeholder': "Enter company's website"})
        for field in ['email',
                   'password1',

                   self.fields[field].widget.attrs['class'] = "col-lg-4 col-md-12 col-sm-12 col-xs-12 offset-lg-2 ml-6 form-control"
                   self.fields[field].widget.attrs['style'] = "padding:20px;"

        self.fields['photo'].widget.attrs['class'] = "col-lg-8 col-md-12 col-sm-12 col-xs-12 offset-lg-1 "


    class Meta:
        model = User
        widgets = {
        "email": forms.fields.TextInput(attrs={'placeholder':'Enter your email'}),
        }
        fields = ('email',
                   'password1',
                  'first_name',
                  'last_name',
                   'photo',
                   'bio',
                   'designation',

                   'markets',
                   'linkedin')

这是我的用户更改表

class EditProfileForm(UserChangeForm):

    def __init__(self, *args, **kwargs):
        super(UserChangeForm, self).__init__(*args, **kwargs)

        for field in [
                    'first_name',

        )```

推荐答案

基本上，您是在获取实例，但不仅可以更新图片。

Basically you are getting the instance but you are not only able to update only the picture.
