新手求助,几条linux命令,想写成脚本,求助
现在有几条命令,想写成脚本,用到的时候,直接执行脚本操作,求大神帮助 0、先登录服务器,192.168.196.1 1、进入项目代码目录/home/data/docker/chinaee/ee/project , 2、执行sudo git pull 拉取代码 3、 执行表结构变更(非必须,只在有表结构变更时需要) 1)sudo docker exec -it chinaee_eebash 进入docker容器 2)source /opt/django/venv/bin/activate 激活virtualenv虚拟环境 3)python manage.py migrate执行表结构变更。(有时执行python manage.py migrate会报错,是代码自动生成的表结构变更有问题,需要研发手动处理) 4)exit退出docker容器 4、 重启docker容器 sudo docker-compose -f etc/docker-compose.yml restart ,重启docker容器
django如何将mysql中表的内容通过models.py在网页端显示
各位朋友们好,mysql数据库中有1张表student包含了name,age两个字段,共1000条数据,现在我想通过django在网页端展示这些数据。看了网上的教程,我在models.py中添加了: from django.db import models import MySQLdb import mysite.settings class student(models.Model): name = models.CharField(max_length = 20) age = models.CharField(max_length = 20) def __str__(self): return self.name 并且在views.py中编写以下代码: # *-* coding: utf-8 *-* import sys reload(sys) sys.setdefaultencoding("utf-8") from django.shortcuts import render, render_to_response from polls.models import student from django.http import HttpResponse import MySQLdb import mysite.settings def index(request): students = student.objects.all() name = "" for stud in students: name = stud.name break return render_to_response('index.html' , {'students':students , 'name':name}) 在settings.py中设置数据库如下: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', #'NAME': os.path.join(BASE_DIR, 'test'),#database name 'NAME': 'test', 'USER':'root', 'PASSWORD':'123456', 'HOST': 'localhost', 'PORT': '3306', } } 在网页端index.html中编写以下内容 ``` <body> <p>学生数据如下:</p> <table border="10"> {% for student in students %} <tr > <td>{{student.name}}</td> <td>{{student.age}}</td> </tr> {% endfor %} </table> </body> ``` 我执行了python manage.py makemigrations 和 python manage.py migrate,虽然也出现了与mysql中表student对应的blog_student表,但是blog_student中没有内容,而且网页端没有数据显示。 请教各位朋友们,这是什么原因呢?该如何显示数据啊? 希望朋友们能指点一下,万分感谢。
有没有谁知道libmysqlclient-dev这个依赖包的下载地址?

dango中inspectdb 命令问题
我通过pycharm里边的tools中的Run manage.py Task 中输入 inspectdb命令后,会显在pycharm中示出1个model信息,而不是生成一个新的models.py文件。 如图所示: ![图片说明](https://img-ask.csdn.net/upload/201812/27/1545878003_882066.jpg) 有三个问题: 1.请问接下来的操作 是否是 将 显示出来的model信息,粘贴到model.py文件夹内? 2.通过inspectdb 生成的model信息是不是应该检查一遍它的类型啊,如果和数据库的某个字段的类型不匹配,那在做migrate的时候,会不会把这个表相应的字段给改了? 3.如果执行完 makemigrations 显示 的消息为:如下图 ![图片说明](https://img-ask.csdn.net/upload/201812/27/1545880574_998095.png) 但是 我这个字段有数据,也会把这列全都删除???我认为这样有些危险。 以上请教大神。
