Django实现上传图片功能(上传图片图片)

本文实例为大家分享了Django实现上传图片的具体代码，供大家参考，具体内容如下

1.设置存放上传的图片的文件夹

settings.py

MEDIA_ROOT = os.path.join(BASE_DIR, 'media').replace('\\', '/')
MEDIA_URL = '/media/'

2.创建图片路径的表结构

models.py

# 存放图片的表
class Avatar(models.Model):
 user = models.CharField(max_length=100)
 photo = models.ImageField(upload_to='photos', default='avatar.jpg')

3.构建并实施迁移文件

python manage.py makemigrations
python manage.py migrate

4.添加路径

urls.py

from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [  
  path('upload/', views.UpLoadInfo),
 ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

5.写逻辑

在view.py

# 上传图片
def UpLoadInfo(request):
 if request.method == 'POST':
  # img = request.FILES.get('photo')
  # user = request.FILES.get('photo').name
  new_img = models.Avatar(
photo=request.FILES.get('photo'),  # 拿到图片
user=request.FILES.get('photo').name  # 拿到图片的名字
  )
  new_img.save()  # 保存图片
  return HttpResponse('上传成功！')
 return render(request, 'upload.html')

6.添加html页面

文件夹templates

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>Title</title>
</head>
<body>
<form action="/upload/" method="POST" enctype="multipart/form-data">
{% csrf_token %}
 <input name="photo" type="file" >
 <button id="upload" type="submit">上传头像</button>
</form>
</body>
</html>

7.效果

运行项目，进入upload查看
