python Django调用数据库出错
显示没有backens.mysql模块,手动调用backens也显示没有,但很明显是有这个文件的 调用Django其他模块没问题,说明路径没问题。 我在stackoverflow等网站上看的是说我的版本有问题,但不知道是python版本还是Django版本,我的python必须要用2.7(服务器要求) 数据库配置没问题。 ![问题1](https://gss0.baidu.com/-Po3dSag_xI4khGko9WTAnF6hhy/zhidao/pic/item/3bf33a87e950352addd62b0e5a43fbf2b2118b04.jpg) ![问题](https://gss0.baidu.com/94o3dSag_xI4khGko9WTAnF6hhy/zhidao/pic/item/80cb39dbb6fd526648b63212a218972bd4073612.jpg) 求大牛指导解决方法

python django models 中的返回值问题
首先是python3,django2.1.4, from django.db import models class Event(models.Model): name = models.CharField(max_length=100) def _str_(self): return self.name 但是显示的结果却是 EventObject, 而不是输入的name的内容。求解!
python+django能够同时使用mongodb和mysql两种数据库引擎吗?
各位朋友们好,我原来做一个项目:因为表没有关联,所以用的是非关系型数据库mongodb,项目开发环境用的是python+django,部署在ubuntu上。当时用了pymongo做python和mongodb的连接,用mongoengine做了django与mongodb的连接。 现在来了新的需求,表之间有关联,因此我准备添加一个mysql数据库。 请教各位朋友们,django展示网页的时候,能够同时展示mongodb中表的内容和mysql中表的内容吗?settings.py中应该如何配置数据库呢? 希望朋友们能指点一下,万分感谢。

django连接mysql提示 django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module. Did you install mysqlclient? 也就是说要我pip install mysqlclient 可我安装mysql的时候自带MySQL Connector Python 8.0 for Python 3.7 C:\Program Files\MySQL\MySQL Connector Python 8.0 for Python 3.7 也就是说我只要告诉django连接mysql用这个目录里的文件就好了... 可我怎么才能让django知道这件事...

django执行python manage.py runserverbao'cuo

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过...

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入 假设现有4个人...
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
