Python常用包地址：若windows安装出错 ，可以去这里找想要的包——> [https://www.lfd.uci.edu/~gohlke/pythonlibs/][https_www.lfd.uci.edu_gohlke_pythonlibs]

1.  django-simple-captcha用于验证码的包(我也是从这里学到的：[https://www.cnblogs.com/zhaijunming5/p/7570180.html][https_www.cnblogs.com_zhaijunming5_p_7570180.html])

*  下载安装django-simple-captcha
 *  INSTALLED\_APPS中添加：'captcha',
 *  配置url：url(r'^captcha/', include('captcha.urls')),
 *  数据库迁移
 *  app中新建form，并创建form对象

*  新建views对象（记得导入要用的包和模块）

*  配置views的url：

*  html网页取值![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0xpc2FZYW5nOTQ_size_16_color_FFFFFF_t_70 2][]

效果：

（1）进入页面

（2）验证码错误

2.定时任务

from apscheduler.schedulers.background import BackgroundScheduler\#导包

scheduler = BackgroundScheduler()\#声明对象

from django\_apscheduler.jobstores import DjangoJobStore

\# If you want all scheduled jobs to use this store by default,

\# use the name 'default' instead of 'djangojobstore'.

scheduler.add\_jobstore(DjangoJobStore(), 'djangojobstore')

from django\_apscheduler.jobstores import register\_events

@scheduler.scheduled\_job("interval", seconds=1000, id="job")

\#方法定义

def job():

time.sleep(10)\#每隔10秒打印一次

print("hello world！")

\#任务开启

scheduler.start()

3.富文本编辑器

(1)富文本编辑器用于Xadmin

由于djangoueditor虚拟环境安装的只适合用于py2，则要去github上下载最新的来适用于py3，

1.  将下载下来的解压到extra\_apps中
2.  在installed\_apps（setting.py）中引入:'DjangoUeditor',
3.  配置url：url(r'^ueditor/',include('DjangoUeditor.urls' )),
4.  修改model：

5.xadmin插件中添加ueditor插件，内容如下：

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)

6.xadmin插件init.py中添加ueditor用于初始化检查

7使用方式：(a) adminx.py中: style\_fields = \{" testField ": "ueditor"\}

(b)html中解析字段时要防止转义：\{% autoescape off %\}

\{ \{ TestModel.testField\}\}

\{% endautoescape %\}

(2)富文本用于前端

1.  views中引入from django.forms import forms、from DjangoUeditor.forms import UEditorField
2.  声明form类并设置富文本各项参数class FormStyle(forms.Form): test = UEditorField(u'描述', width=600, height=300, toolbars="full", imagePath="images/%(basename)s\_%(datetime)s.%(extname)s", filePath="/files/", )
3.  若model传值可以对对象进行初始赋值form.fields\["test"\].initial = xxx. test (test是model中的一个富文本字段, form是含有富文本字段的form对象)，然后将富文本对象更新到要传值的字典中\{“form”: form\}
4.  前端引入富文本样式\{% form.media %\}
5.  前端引入值\{ \{ form \}\}

以上均属于个人学习之后的总结，若有不妥，请各位前辈多指教。
