django将图片上传数据库后在前端显式的方法

1、使用ImageField先安装pillow模块

pip install pillow

2、在app的models中设置

class Image(models.Model):
  pic_name=models.CharField('图片',max_length=40)
  pic_path=models.ImageField(upload_to="pic_folder/",default='pic_folder/None/no_image.pig')

3、在app的view中设置获取图片的方法

def upload_pic(request):
  pic=Image.objects.all()
  return render(request,'blog/image.html',{'pic':pic})

4、在settings中设置

1、添加media模板
TEMPLATES = [
 {
  'BACKEND': 'django.template.backends.django.DjangoTemplates',
  'DIRS': [os.path.join(os.path.dirname(__file__), 'templates'),os.path.join(os.path.dirname(__file__), 'static'), ],

  'APP_DIRS': True,
  'OPTIONS': {
   'context_processors': [
    'django.template.context_processors.debug',
    'django.template.context_processors.request',
    'django.contrib.auth.context_processors.auth',
    'django.contrib.messages.context_processors.messages',
    'django.template.context_processors.media',
   ],
  },
 },
]

2、设置media的路径
MEDIA_URL='media/'
MEDIA_ROOT=os.path.join(BASE_DIR,'media').replace('\\','/')

5、在app的urls中设置

from django.conf.urls.static import static
 from django.conf import settings

 urlpatterns = [
  url(r'^pic$', views.upload_pic, name='upload_pic')
 ]+static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

通过admin登录后上传图片，会在站点下生成media/pic_folder的目录
