Question

最近我正在开发一个移动应用程序（android）。对于后端，我正在使用Django REST。首先，我创建了一个用户API。哪个帖子用户的全名和来自Google登录名的电子邮件。我的移动应用程序的主要目标是解决用户问题。在这里，用户将从移动应用程序上传照片，该照片将保存在已注册的指定用户下。最后，我想知道如何在已注册用户下在django后端中发布图像。如果有人知道了，请发布。帮助将不胜感激。

这里是model.py

from django.db import models

# Creating krisi_user Model

class krisi_user(models.Model):
    full_name = models.CharField(max_length=250)
    email = models.CharField(max_length=100)

    def __str__(self):
        return self.full_name

此处Serializer.py

from rest_framework import serializers # imported serializers fror rest framework

from .models import krisi_user # added Model from model.py

#class for krisi_user serializer
class krisi_user_searializers(serializers.ModelSerializer):

    # meta class for field which we want to show


    class Meta:
        model = krisi_user
        fields = ('id','full_name','email')

此处views.py

from django.shortcuts import render

from rest_framework import viewsets


'''importing krisi_user model and serializers 
in the views file '''

from .models import krisi_user
from .serializers import krisi_user_searializers


#class for krisi_user_view

class krisi_user_view(viewsets.ModelViewSet):
    queryset = krisi_user.objects.all()
    serializer_class = krisi_user_searializers

Answer 1

You're gonna want to use a FileField, as such:

profile_photo = models.FileField(
    upload_to='user/profile_photo', null=True, blank=True
)

There's good documentation of the FileField and how to use it at https://docs.djangoproject.com/en/2.1/ref/models/fields/#filefield.

首先将ImageField添加到模型中。

1）将图像字段添加到模型中

from django.db import models

# Creating krisi_user Model

class krisi_user(models.Model):
    full_name = models.CharField(max_length=250)
    email = models.CharField(max_length=100)
    image = models.ImageField(upload_to='images')


    def __str__(self):
        return self.full_name

2）修改序列化器以包括图像字段

from rest_framework import serializers # imported serializers fror rest framework

from .models import krisi_user # added Model from model.py

#class for krisi_user serializer
class krisi_user_searializers(serializers.ModelSerializer):

    # meta class for field which we want to show


    class Meta:
        model = krisi_user
        fields = ('id','full_name','email','image')

3）在您的views.py中使用APIView。要上传图像，您需要MultiPartParser，您可以将其添加到APIView。

class kriri_user_view(APIView):
    parser_classes = (MultiPartParser, )

    def post(self, request, format=None):
        serializer = krisi_user_searializers(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return JsonResponse(serializer.data)
        return JsonResponse(serializer.errors, status=400)
