django-文件上传

1. 如何配置上传的文件路径
2. 如何解决富文本编辑器文件上传的问题

配置上传：

1、在settings.py中配置MEDIA_URL和MEDIA_ROOT
2、urls.py中配置路由

from django.views.static.serve
from django.conf import settings

url(r"^uploads/(?P<path>.*)$", \
                serve, \
                {"document_root": settings.MEDIA_ROOT,}),

3、在model中设置图片的上传位置和路径

class User(AbstractUser):
    avatar = models.ImageField(upload_to='avatar/%Y/%m',\
    default='avatar/default.png', max_length=200, \
    blank=True, null=True, verbose_name='用户头像')
    ...

富文本编辑器文件上传

config.js:
KindEditor.ready(function(K) {
    K.create('textarea[name="content"]', {
        width : "800px",
                height : "200px",
        uploadJson:
         '/admin/upload/kindeditor',
    });
});

urls配置：

url(r'^admin/upload/(?P<dir_name>[^/]+)$', upload_image, name='upload_image'),

upload.py:

from django.http import HttpResponse
from django.conf import settings
from django.views.decorators.csrf import csrf_exempt
import os
import uuid
import json
import datetime as dt

@csrf_exempt
def upload_image(request, dir_name):
    ##################
    #  kindeditor图片上传返回数据格式说明：
    # {"error": 1, "message": "出错信息"}
    # {"error": 0, "url": "图片地址"}
    ##################
    result = {"error": 1, "message": "上传出错"}
    files = request.FILES.get("imgFile", None)
    if files:
        result =image_upload(files, dir_name)
    return HttpResponse(json.dumps(result), content_type="application/json")

#目录创建
def upload_generation_dir(dir_name):
    today = dt.datetime.today()
    dir_name = dir_name + '/%d/%d/' %(today.year,today.month)
    if not os.path.exists(settings.MEDIA_ROOT + dir_name):
        os.makedirs(settings.MEDIA_ROOT + dir_name)
    return dir_name

# 图片上传
def image_upload(files, dir_name):
    #允许上传文件类型
    allow_suffix =['jpg', 'png', 'jpeg', 'gif', 'bmp']
    file_suffix = files.name.split(".")[-1]
    if file_suffix not in allow_suffix:
        return {"error": 1, "message": "图片格式不正确"}
    relative_path_file = upload_generation_dir(dir_name)
    path=os.path.join(settings.MEDIA_ROOT, relative_path_file)
    if not os.path.exists(path): #如果目录不存在创建目录
        os.makedirs(path)
    file_name=str(uuid.uuid1())+"."+file_suffix
    path_file=os.path.join(path, file_name)
    file_url = settings.MEDIA_URL + relative_path_file + file_name
    open(path_file, 'wb').write(files.file.read())
    return {"error": 0, "url": file_url}
