python-0004-django站点

站点

django自带站点用来操作增删改查

国际化（汉化）

项目setting.py

# LANGUAGE_CODE = 'en-us'
LANGUAGE_CODE = 'zh-Hans'
# TIME_ZONE = 'UTC'
TIME_ZONE = 'Asia/Shanghai'
USE_I18N = True
USE_L10N = True
USE_TZ = True

创建模型

在子应用的models.py中创建，如下：

from django.db import models

# Create your models here.
from django.db import models


class BookInfo(models.Model):
    name = models.CharField(max_length=15)

    def __str__(self):
        return self.name
    pass


class PeopleInfo(models.Model):
    name = models.CharField(max_length=15)
    gender = models.BooleanField()
    book = models.ForeignKey(BookInfo,on_delete=models.CASCADE)
    pass

生成迁移文件

在pycharm的终端或虚拟环境执行

python manage.py makemigrations

执行迁移

在pycharm的终端或虚拟环境执行

python manage.py migrate

此时会在项目的db.sqlite3中生成信息

注册模型到站点

在子应用的admin.py中注册，示例如下：

from django.contrib import admin

# Register your models here.
from book.models import BookInfo,PeopleInfo

admin.site.register(BookInfo)
admin.site.register(PeopleInfo)

重写__str__

目的：显示更全的数据

重写model的__str__，如：

from django.db import models

# Create your models here.
from django.db import models


class BookInfo(models.Model):
    name = models.CharField(max_length=15)

    def __str__(self):
        return self.name
    pass


class PeopleInfo(models.Model):
    name = models.CharField(max_length=15)
    gender = models.BooleanField()
    book = models.ForeignKey(BookInfo,on_delete=models.CASCADE)
    pass
