更新Djanngo 1.11中的用户配置文件

Question

我是一名新的开发人员，我想知道您是否可以帮助我，通过编辑表单更新我的用户/用户配置文件的值。你知道吗

一开始我不知道，但现在我知道我可以扩展（默认）用户模型，这样做可以避免为配置文件创建一个新模型用户配置文件，并使事情更简单（例如，使用通用视图）。你知道吗

因为我还在学习，所以我决定尝试一种变通方法来促使自己思考，而不是要求一个完整的解决方案。你知道吗

我已经在这里和Django的官方文档中找到了类似的问题，但是由于我没有遵循特定的配方，所以我找不到合适的方法来解决它。你知道吗

到目前为止我得到的是：

型号.py

class UserProfile(models.Model):
    GENDER_CHOICES = ( 
        ('M', 'Masculino'),
        ('F', 'Feminino')
    )

    user = models.OneToOneField(User, on_delete=models.CASCADE) 
    profile_image = models.ImageField(upload_to='uploads/', blank=True, null=True)
    gender = models.CharField(max_length=40, blank=True, null=True, choices=GENDER_CHOICES)
    birthday = models.DateField(blank=True, null=True)
    address = models.TextField(max_length=300, blank=True, null=True)
    city = models.TextField(max_length=50, blank=True, null=True)
    country = models.TextField(max_length=50, blank=True, null=True)

    def __str__(self):
        return str(self.id)

表单.py

class CustomUserForm(ModelForm):
    class Meta:
        model = User
        fields = [
            'username', 'id', 'first_name', 'last_name', 'email', 'last_login', 'date_joined'
        ]
        widgets = {
            'username': forms.TextInput(attrs={'class': 'form-control'}),
            'id': forms.TextInput(attrs={'class': 'form-control', 'readonly': 'readonly'}),
            'first_name': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Insira seu nome'}),
            'last_name': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Insira seu sobrenome'}),
            'email': forms.EmailInput(attrs={'class': 'form-control', 'placeholder': 'Insira seu email. Ex: seuemail@gmail.com'}),
            'last_login': forms.DateInput(attrs={'class': 'form-control-plaintext rdonly', 'readonly': 'readonly'}),
            'date_joined': forms.DateInput(attrs={'class': 'form-control-plaintext rdonly', 'readonly': 'readonly'}),
        }

class UserProfileForm(ModelForm):
    class Meta:
        model = UserProfile
        fields = [
            'profile_image', 'gender', 'birthday', 'address', 'city', 'country'
        ]
        widgets = {
            'profile_image': forms.ClearableFileInput(attrs={'class': ''}),
            'gender': forms.Select(attrs={'class': 'form-control'}),
            'birthday': forms.DateInput(attrs={'class': 'form-control'}),
            'address': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Insira seu endereço completo'}),
            'city': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Insira sua cidade. Ex: Recife-PE'}),
            'country': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Informe o país em que vive'}),
        }

视图.py

class Profile(View):

    def get(self, request, *args, **kwargs):
        submitted = False
        if request.user.is_authenticated():
            # Getting the Target objects in the DB
            targetuserprofile = UserProfile.objects.get(user=request.user)
            # Instanciating forms and passing current values
            profile_form = UserProfileForm(instance=targetuserprofile)
            user_form = CustomUserForm(instance=request.user)
            user_form.id = request.user.id
        else:
            return HttpResponseRedirect('/login/?next=/')
        if 'submitted' in request.GET:  
            submitted = True
        context = {
            'user_form': user_form,
            'profile_form': profile_form,
            'submitted': submitted
        }
        return render(request, "registration/profile.html", context)

    def post(self, request, *args, **kwargs):
        submitted = False
        # Creating new forms
        profileform_formclass = UserProfileForm
        userform_formclass = CustomUserForm
        # Getting the values passed throught POST method
        profile_form = profileform_formclass(request.POST, request.FILES)
        user_form = userform_formclass(request.POST)
        # Getting the Target objects in the DB
        targetuserprofile = UserProfile.objects.filter(user=request.user)
        targetuser = request.user
        # Validating forms and saving
        if profile_form.is_valid() & user_form.is_valid():
            profile = profile_form.save(commit=False)
            usr = user_form.save(commit=False)
            targetuserprofile.user = targetuser
            targetuserprofile.profile_image = profile.profile_image
            targetuserprofile.gender = profile.gender
            targetuserprofile.birthday = profile.birthday
            targetuserprofile.address = profile.address
            targetuserprofile.city = profile.city
            targetuserprofile.country = profile.country
            targetuserprofile.save()
            targetuser.first_name = usr.first_name
            targetuser.last_name = usr.last_name
            targetuser.email = usr.email
            targetuser.save()
        else:
            return HttpResponse("Erro")
        submitted = True
        context = {
            'submitted': submitted        
        }
        return render(request, "registration/profile.html", context)

配置文件.html（仅相关部分）

<form action="" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ profile_form.profile_image }}
    {{ user_form.first_name }}
    {{ user_form.last_name }}
    {{ user_form.email }}
    {{ profile_form.gender }}
    {{ profile_form.birthday }}
    <label class="profile_readonly"></label>
    {{ user_form.id }}
    <label class="profile_readonly"></label>
    {{ user_form.last_login }}
    <label class="profile_readonly"></label>
    {{ user_form.date_joined }}
    {{ profile_form.address }}
    {{ profile_form.city }}
    {{ profile_form.country }}
    <input class="btn btn-primary" type="submit" value="Salvar" />
</form>

获取方法（视图.py）工作正常，以便在窗体上显示当前的用户/用户配置文件值，但是post没有更新值。可能是我在验证它时做错了什么，因为我从else语句中得到了“错误”消息。你知道如何正确更新我的用户/用户配置文件吗？你知道吗
