孤人 提交于 2021-02-16 10:21:20
问题 I'm trying to deploy a small django app on Heoroku using the documentation provided. But my app does not run and when I look at the logs on Heroku it looks like the problem is with the procfile. Here are the contents of the procfile. Is this the correct syntax? web: gunicorn hashem3.wsgi -b 0.0.0.0:$PORT And here is what the Heroku logs show: 2012-07-21T03:02:58+00:00 heroku[slugc]: Slug compilation started 2012-07-21T03:04:28+00:00 heroku[api]: Add shared-database:5mb add-on by 2012-07-21T03

Django signals from admin

此生再无相见时 提交于 2021-02-16 09:24:10
问题 How can I distinguish between, for example, a post_save that comes from a regular view and one that comes from the admin? 回答1: By overriding ModelAdmin.response_add you may get a similar functionality, as it seems that the django admin does not sent any signals.

So by overriding the response_add method in our own ModelAdmin class we can execute code

点击上方“ Python进击者 ”,选择“ 星标 ”公众号 超级无敌干货推送给你!!! 机器之心报道 作者:魔王、小舟 还在用马赛克的方式隐藏密码? 小心被「看穿」。 像素化(又称马赛克)是一种常见的打码方式,通过降低图像中部分区域的分辨率来隐藏某些关键信息,比如: 再比如: 看图找马赛克!(找不到请看右侧原图) 但是,在你想隐藏信息的同时,有一些技术却反其道而行之,试图将图片还原为原始状态。 最近,一个名为 Depix 的 GitHub 项目爆火,上线三天 star 量已经高达 6.9k。项目作者 Sipke Mellema 是一名信息安全顾问。 项目地址 : https://github.com/beurtschipper/Depix Depix 能够从像素化图像截图中恢复原图中包含的文字密码。该项目适用于使用线性方框滤波器(linear box filter)创建的像素化图像。如下图所示,项目作者给出了像素化图像、恢复之后的效果和原图的对比结果: 马赛克打得够严实了,不过 Depix 还是基本解读出了被隐藏的信息。 如何使用? 使用 Depix 从像素化图像截图中恢复文字密码,操作也比较简单: 从截图中分割出矩形像素化 block; 在具有相同字体设置(包括文本大小、字体、颜色、hsl)的编辑器中,粘贴待处理字符的德布鲁因(De Bruijn sequence)。

The only thing I've managed so far is to run the SAR command in a terminal, parse the results to a text file and then print out the text file using import os from django.shortcuts import render def
