python - 在 django 中更新

问题描述

我是 django 的新手，我想制作一个更新视图，但我无法成功。我有页一个显示用户信息的页面，当我按下“更新我的个人资料”按钮时，我想更新或保存（即，如果我将“Laszlo”更改为“Lucy”，我想更新它，如果我写'nickname' 输入：'NICKNAME' 我想将该信息保存到 de dababase 中，以便下次访问此页面时向我显示有关用户的所有信息）

我的模型：'UserProfile'（即'User'）和'User_Details'（它们是1-1关系）

class UserProfile(AbstractUser):
    pass


class User_Details(models.Model):
    user = models.OneToOneField(UserProfile, on_delete=models.CASCADE)
    first_name = models.CharField(max_length=50, blank = True)
    last_name = models.CharField(max_length=50, blank=True)
    gender = models.CharField(max_length=6, blank=True, default='')
    image = models.ImageField(upload_to='avatar_image', blank=True, null=True)
    public_info=models.CharField(max_length=100, blank=False, default='')
    nickname=models.CharField(max_length=100,blank=True,default="")
    website=models.CharField(max_length=100,blank=True,default="")

我显示信息的观点：

class ShowProfile(APIView):
    renderer_classes = [TemplateHTMLRenderer]
    template_name = 'profile.html'


    def get(self, request, pk, format=None):
        details = UserProfile.objects.get(id=pk)
        serializer = UserProfileSerializer(details)
        pprint.pprint(json.loads(JSONRenderer().render(serializer.data)))
        return Response({'seri':serializer.data})

序列化器：

class UserDetailsSerializer(serializers.ModelSerializer):
    class Meta:
        model = User_Details
        fields = (
            'first_name',
            'last_name',
            'gender',
            'public_info',
            'nickname',
            'website'
        )

class UserProfileSerializer(serializers.ModelSerializer):
    user_details = UserDetailsSerializer()
    lookup_field = 'username'
    class Meta:
        model = UserProfile
        fields = ('id', 'user_details')

{% endblock %}

我试图做到这一点（进入“ShowProfile”视图）：

    def put(self, request,pk):
        serializer = ProfileUpdateSerializer()
        post = request.POST.copy()
        serializer.update(validated_data=dict(post))
        return HttpResponseRedirect('/account/login.html')

串行器

class ProfileUpdateSerializer(serializers.HyperlinkedModelSerializer):

    first_name = serializers.CharField(source='User_Details.first_name')
    last_name = serializers.CharField(source='User_Details.last_name')
    gender = serializers.CharField(source='User_Details.gender')
    public_info = serializers.CharField(source='User_Details.public_info')
    # image=serializers.ImageField(source='User_Details.image')
    nickname = serializers.CharField(source='User_Details.nickname')
    website = serializers.CharField(source='User_Details.website')

    class Meta:
        model = User_Details
        fields = ('first_name', 'last_name', 'gender', 'public_info', 'nickname', 'website')

    def update(self, validated_data, uid):
        user = UserProfile.objects.get(id=uid)


        firstname = validated_data.pop('user_details.firstname')[0]
        lastname = validated_data.pop('user_details.lastname')[0]

        user.user_details.firstname = firstname
        user.user_details.lastname = lastname

        # if avatar:
        #     user.user_details.avatar = avatar
        # if password != '':
        #     user.set_password(password)

        user.user_details.save()
        user.save()
        return user

在模板中我用这个改变''：

 <form action="{% url 'show_profile'  pk=user.id %}" method="PUT" enctype="multipart/form-data">

我不知道怎么做？我该怎么做？谢谢！

解决方案

问题出在<form action="{% url 'show_profile' pk=user.id %}" method="PUT" enctype="multipart/form-data">. PUThtml 标签中没有方法form。您必须使用 javascript 来发送此类请求。

PS 可以使用 发送类似 put 的请求form，但它看起来很难看，而且不会是 REST
