Django DEMO地址 ios-swift DEMO地址
1. 软件环境:
django ~1.11
Python 3.6.1
Anaconda 4.4.0
Mac sbulime
2. 新建项目
django-admin.py startproject django_uploadImg_userHeadChange_rest
复制代码3. 新建APP
python manage.py startapp upload_test
复制代码4. 新建 mySerializers.py文件，项目构成如下
5. models.py
from django.db import models
class haveFunUser(models.Model):
user_id = models.AutoField(primary_key=True)
name = models.CharField(max_length=128)
phone = models.CharField(max_length=11,unique=True)
date_joined = models.DateTimeField(auto_now=True) #DateField
gender_choices = ((0,"男"),(1,"女"))
sex = models.IntegerField(choices=gender_choices,default=1)
age = models.PositiveIntegerField(default=18)
address = models.CharField(max_length=80,null=True,blank=True)
email = models.EmailField(null=True,blank=True)
img = models.TextField(null=True,blank=True)
user_type_choice=((0,"超级用户"),(1,"普通用户"))
user_type = models.IntegerField(choices=user_type_choice,default=1)
passwd = models.CharField(max_length=64)
def __str__(self):
return self.name,self.phone
class userHeadImage(models.Model):
image_id = models.AutoField(primary_key=True)
image = models.ImageField(max_length=None,upload_to='head_images',null=True, blank=True)
uploaded_by = models.ForeignKey(haveFunUser)
复制代码6. mySerializers.py
from django.contrib.auth.models import *
from rest_framework import serializers
from . import models
import time
from django.conf import settings
class ImageSerializer(serializers.ModelSerializer):
image = serializers.ImageField(max_length=None, use_url=True) #use_url=True是否显示完整的路径
def create(self, validated_data):
data = self.context.get('request').data.dict()
user_id = data['user_id']
print('xxxx=------',user_id,'xasaaaaa=---',validated_data)
validated_data.update({'uploaded_by_id': user_id})
return models.userHeadImage.objects.create(**validated_data)
class Meta:
model = models.userHeadImage
fields = ('image_id','image')
#用户基本信息
class UserSerializer(serializers.ModelSerializer):
time_join = serializers.SerializerMethodField()
img = serializers.SerializerMethodField()
def get_time_join(self,obj):
t = obj.date_joined
return t.strftime('%Y-%m-%d %X')
def get_img(self,obj):
image = ImageSerializer(models.userHeadImage.objects.filter(uploaded_by_id__exact=obj.user_id).first()).data
if image:
return image['image']
else:
return ''
class Meta:
model = models.haveFunUser
fields = ('user_id','name', 'phone','time_join','sex','age','address','email','img','user_type','passwd')
复制代码7. settings.py
注册APP
INSTALLED_APPS = [
'rest_framework',
'upload_test',
]
复制代码要想外网内网都能访问需要：
ALLOWED_HOSTS = ['*']
复制代码设置图像储存的文件路径以及获取图像的网络路径
MEDIA_ROOT = os.path.join(BASE_DIR, 'image')
MEDIA_URL = '/media/'
复制代码REST_FRAMEWORK设置
REST_FRAMEWORK = {
'DEFAULT_PERMISSION_CLASSES': ('rest_framework.permissions.AllowAny',),
'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
'PAGINATE_BY': 10,
'DEFAULT_PARSER_CLASSES': (
'rest_framework.parsers.JSONParser',
'rest_framework.parsers.FormParser',
'rest_framework.parsers.MultiPartParser',
'rest_framework.parsers.FileUploadParser'
),
}
复制代码8. 在django_uploadImg_userHeadChange_rest下的urls.py中配置自己APP的URL文件
from django.conf.urls import url,include
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^api-auth/',include('rest_framework.urls', namespace='rest_framework')),
url(r'^haveFun/', include('upload_test.urls',namespace='haveFun')),
]+ static(settings.MEDIA_URL , document_root=settings.MEDIA_ROOT )

复制代码10. APP中urls.py配置
from django.conf.urls import url,include
from . import views
urlpatterns = [
url(r'^upload_head_image$', views.UploadViewSet.as_view()),
url(r'^register$', views.UserRegisterAPIView.as_view()),
url(r'^login$', views.UserLoginAPIView.as_view()),
]
复制代码11. 开始运行项目
python managey makemigrations
python manage.py migrate
python manage.py runserver 192.168.38.127:8000
复制代码192.168.38.127:8000是我电脑自己的WiFiIP，当你手机和你电脑同一WiFi就可以连接项目进行测试
