Django ueditor插件的安装

下载地址：https://github.com/zhangfisher/DjangoUeditor

进入mxonline的虚拟环境

Python setup.py install

进行安装

在settings.py中引入ueditor

在url配置中引入

# 富文本相关url
url(r'^ueditor/',include('DjangoUeditor.urls' )),

在课程中引入富文本

from DjangoUeditor.models import UEditorField

替换models中具体的字段

# 详情用富文本代替
detail = UEditorField(verbose_name=u'课程详情', width=600, height=300, imagePath="courses/ueditor/", filePath="courses/ueditor/",default='')

编写插件

Ueditor.py

import xadmin
from xadmin.views import BaseAdminPlugin, CreateAdminView, ModelFormAdminView, UpdateAdminView
from DjangoUeditor.models import UEditorField
from DjangoUeditor.widgets import UEditorWidget
from django.conf import settings

class XadminUEditorWidget(UEditorWidget):
    def __init__(self,**kwargs):
        self.ueditor_options=kwargs
        self.Media.js = None
        super(XadminUEditorWidget,self).__init__(kwargs)

class UeditorPlugin(BaseAdminPlugin):

    def get_field_style(self, attrs, db_field, style, **kwargs):
        if style == 'ueditor':
            if isinstance(db_field, UEditorField):
                widget = db_field.formfield().widget
                param = {}
                param.update(widget.ueditor_settings)
                param.update(widget.attrs)
                return {'widget': XadminUEditorWidget(**param)}
        return attrs

    def block_extrahead(self, context, nodes):
        js = '<script type="text/javascript" src="%s"></script>' % (settings.STATIC_URL + "ueditor/ueditor.config.js")         #自己的静态目录
        js += '<script type="text/javascript" src="%s"></script>' % (settings.STATIC_URL + "ueditor/ueditor.all.min.js")   #自己的静态目录
        nodes.append(js)

xadmin.site.register_plugin(UeditorPlugin, UpdateAdminView)
xadmin.site.register_plugin(UeditorPlugin, CreateAdminView)

在init文件中引入ueditor插件

添加课程可以看到富文本已经引入了

使用上传图片的时候报错如下：

D:\python2.7.16\Lib\importlib\__init__.py:37: RemovedInDjango110Warning: django.core.context_processors is deprecated in favor of django.template.context_processors.

pydev debugger: process 34408 is connecting

解决办法：

找到源码修改views.py 文件中的get_ueditor_controller方法

添加装饰器

步骤总结：

前端显示的时候直接显示了转义后的代码

解决办法：在模板页面关闭自动转义

引入导入excel的功能

修改__init__.py 增加’excel’插件

Excel.py插件

# _*_ coding:utf-8 _*_
# __author__ == 'jack'
# __date__ == '2019-11-09 11:49 AM'

import xadmin
from xadmin.views import BaseAdminPlugin, ListAdminView
from django.template import loader

# excel导入
class ListImportExcelPlugin(BaseAdminPlugin):
    import_excel = False

    def init_request(self, *args, **kwargs):
        return bool(self.import_excel)

    def block_top_toolbar(self, context, nodes):
        nodes.append(loader.render_to_string("xadmin/excel/model_list_top.boolbar.import.html", context_instance=context))

xadmin.site.register_plugin(ListImportExcelPlugin, ListAdminView)

具体的html
