Pycharm Django新建项目的一个问题
最近在看python编程入门到实践这本书,然后试着Pycharm新建Django项目,遇到一个问题 运行的时候提示 You have 13 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions. Run 'python manage.py migrate' to apply them. 于是我在命令行中运行 python manage.py migrate 但是结果提示: File "<input>", line 1 python manage.py migrate SyntaxError: invalid syntax 实在是不知道为什么 这个命令应该在哪里运行呢?求教 谢谢!

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。

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。
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。

程序员接私活怎样防止做完了不给钱?
