图片上传到Django中的“无”文件夹

标签： python django python-2.7 image-uploading django-1.11

我正在尝试通过Ajax上传图像。图像可以很好地上传，但会在MEDIA_ROOT值和upload_to的{​​{1}}参数之间的“无”文件夹中传送。

我当前的设置如下：

ImageField

在我的应用程序的models.py中：

MEDIA_ROOT = (os.path.join(BASE_DIR, 'static', 'media'))

和

image = models.ImageField(blank=True, null=True, upload_to=get_image_path)

当我上传图片时，它会转到def get_image_path(instance, filename): return os.path.join(connection.tenant.schema_name, 'img', 'devices', filename) ，而不是static/media/None/(tenant.schema_name)/img/devices

（在图片中，static/media/(tenant.schema_name)/img/devices是“ ars”）

wrong path image upload

表格如下：

tenant.schema_name

保存段：

class DeviceForm(ModelForm):
    class Meta:
        model = Device
        fields = ['name', 'model', 'serial', 'location', 'note', 'image', 'page', 'address']

是否缺少我的配置？任何帮助将不胜感激

编辑：以下是整个 if request.method == 'POST': post_data = request.POST.dict() form = DeviceForm(post_data, request.FILES) if not form.is_valid(): return JsonResponse({"message": "Form is invalid"}, status=400) obj = form.save() return JsonResponse(obj.to_dict(), safe=False) ：

settings.py

我使用了以下答案建议的配置，但是在import os from django.utils.translation import ugettext_lazy # Build paths inside the project like this: os.path.join(BASE_DIR, ...)

您应该在settings.py文件中定义媒体目录。您要从网站上载的图像和文件，存储在媒体目录中。

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static', 'static_root')

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static', 'static_dirs'),
    )

MEDIA_ROOT = os.path.join(BASE_DIR, 'static', 'media')

MEDIA_URL = '/media/'

您的项目中需要静态目录。树目录如下：

static -
        |-static_root
        |-static_dirs
        |-media

请创建以下4个目录： static ， static_root ， static_dirs ， media

答案 1 :(得分：-1)

在整个项目目录中的同一级别（与manage.py相同的级别）中，将媒体和静态文件创建为文件夹，然后尝试：

PROJECT_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
BASE_DIR = os.path.dirname(PROJECT_DIR)

STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATIC_URL = '/static/'

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

media和static文件夹用于两个完全不同的事物，并且绝对不能将media嵌套在static中。媒体文件夹用于存储用户上传的内容，您定义的MEDIA_ROOT是用户上传的内容上传到的位置（通过upload_to=.....设置了MEDIA_ROOT中的子文件夹）。静态文件夹和（和子文件夹）包含您定义为网站一部分的内容（例如css，js）。

我也会做一个小的更改（不需要request.POST.dict()）：

if request.method == 'POST':
    form = DeviceForm(request.POST, request.FILES)
