Django使用富文本编辑器

1.下载kindeditor
　　网址：http://kindeditor.net/demo.php
2.解压到项目中
　　地址：\static\js\kindeditor-4.1.10
3.删除没用的文件
　　例如：example，php，asp等
4.在需要使用富文本编辑器的model中定义meta类：

class Media:
        js = (
            '/static/js/kindeditor-4.1.10/kindeditor-min.js',
            '/static/js/kindeditor-4.1.10/lang/zh_CN.js',
            '/static/js/kindeditor-4.1.10/config.js',
        )

5.在kindeditor-4.1.10目录中定义config.js文件：

KindEditor.ready(function(K) {
                K.create('textarea[name=需要使用富文本的字段名]',{
                    width:'800px',
                    height:'200px',
　　　　　　　　　　　 uploadJson: '/util/upload/kindeditor',
                });
        });

6.在urls.py中定义文件上传的处理器：

from util.upload import upload_image

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

7.在settings.py中定义文件上传的目录如下：

MEDIA_URL = '/uploads/'

MEDIA_ROOT = os.path.join(BASE_DIR,  'uploads')

8.处理upload的py文件：

# -*- coding: utf-8 -*-
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()) # 保存图片
    return {"error": 0, "url": file_url}
