前置步骤
setting.py文件配置:
添加app目录
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'app01', ]
添加media文件和路径
PROJECT_ROOT = os.path.abspath(os.path.join(os.path.dirname('__file__'))) MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
app目录下models.py配置
from django.db import models # Create your models here. class Test(models.Model): name = models.CharField(max_length=50) image = models.ImageField(upload_to='logo/')
注意:
ImageField() 依赖 Pillow (pip install Pillow)
这里login是目录路径 完整的路径是 /media/logo/图片
这里图片可以通过Django admin后台直接添加
所有设置一下app里 admin.py文件
from django.contrib import admin from app01.models import Test # Register your models here. admin.site.register(Test)
引入models 中的Test类 然后 admin.site.register(Test)
接着加载数据库 写入数据库
创建超级用户
然后就是正常的Django访问配置了:
urls.py配置
注意!!! 这里必须要添加static 目录,后端通过传递/media/logo/图片,而这里是将图片传递到前端浏览器,这样才能访问路径的图片
from django.contrib import admin from django.urls import path from app01 import views from django.conf.urls import url from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('admin/', admin.site.urls), url(r'index/', views.index), ] urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
views.py配置
from django.shortcuts import render,HttpResponse from app01 import models # Create your views here. def index(request): img = models.Test.objects.all() # img = models.Test.objects.filter(id=1)[0].image.url return render(request,'index.html',{'img':img})
从数据库中读取图片路径 然后传递到前端页面.
前端页面:
后台传递的若是: img = models.Test.objects.all()
前端则是:
<body> {% for i in img %} <img src="{{ i.image.url}}"> {% endfor %} </body>
后台传递的若是:img = models.Test.objects.filter(id=1)[0].image.url
前端则是:
<body> {{ img }} </body>
测试:
添加图片以后再 访问index页面
