Django一小时写出账号密码管理系统-巨人网络通讯

1、环境搭建

需安装：
python3.6
Pycharm专业版
django 2.2.6
mysqlclient

pip install django==2.2.6
pip install mysqlclient

2、生成django项目

django-admin startproject yourproject

3、修改数据库引擎为mysql并要数据库中创建对应名字的数据库

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'myblog',        #数据库名
        'USER':'root',           #用户名
        'PASSWORD':'******',     #密码
        'HOST':'127.0.0.1',      #本机地址
        'PORT':'3306',           #端口
    }
}
pip install mysqlclient

4、初始化数据库

python ./manage.py makemigrations
python ./manage.py migrate

5、汉化（修改项目settings.py）

LANGUAGE_CODE = 'zh-hans'

6、启动django项目

cd yourproject
python ./manage.py runserver 0.0.0.0:8000

7、创建django后台管理员

python ./manage.py createsuperuser

8、创建自己的app

python .\manage.py startapp yourapp

9、定义app的数据模型model.py

from django.db import models

# Create your models here.

class SinfoM(models.Model):
    description=models.CharField(max_length=50,verbose_name='描述',null=False,blank=False)
    username=models.CharField(max_length=50,verbose_name='账号',null=False,blank=False)
    password=models.CharField(max_length=50,verbose_name='密码',null=False,blank=False)
    remark=models.CharField(max_length=50,verbose_name='备注',null=True,blank=True)

    class Meta:
        db_table=u'self_info'
        verbose_name=u'个人信息'
        verbose_name_plural=u'个人信息'

    def __unicode__(self):
        return self.username

    def __str__(self):
        return self.username

10、在app的admin中定义页面显示内容

from django.contrib import admin

# Register your models here.

from sinfom.models import SinfoM

class SinfoMAdmin(admin.ModelAdmin):
    # exclude = ('password')
    list_display = (
        'description',
        'username',
        'password',
        'remark'
    )

admin.site.register(SinfoM,SinfoMAdmin)

11、重新执行数据库脚本

python ./manage.py makemigrations
python ./manage.py migrate

12、将app注册到项目的settings.py中

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'yourapp',
]
