BBS项目（二）
可以在本地写或虚拟环境
- 添加虚拟环境
- 如果虚拟环境启动报错：解决 query = query.decode(errors=‘replace‘) AttributeError: ‘str‘ object has no attribute ‘decode‘
- 解决办法
query = query.decode(errors='replace')
'''换成'''
query = errors='replace'
ORM 创建相关表
'''models.py'''
from django.contrib.auth.models import AbstractUser

# Create your models here.
'''扩写auth_user表需要使用AbstractUser'''
# 用户表

表模型
修改admin样式
'''创建超级用户'''

'''修改配置'''
LANGUAGE_CODE = 'zh-hans'

参考：Simple UI
Simple-UI
-
导入：
pip install django-simpleui -
注册：
INSTALLED_APPS = [
'simpleui',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
...
]
样式改变
注册表添加数据
'''admin.py'''
from django.contrib import admin
from blog import models
# Register your models here.
admin.site.register(models.Article)
admin.site.register(models.Blog)
admin.site.register(models.UserInfo)
admin.site.register(models.UpAndDown)
admin.site.register(models.Commit)
admin.site.register(models.Category)
admin.site.register(models.Tag)
应用名改成中文在后台显示
'''apps.py'''
from django.apps import AppConfig
class App01Config(AppConfig):
name = 'blog'
verbose_name = '博客管理'
# 如果想改表名为中文在后台显示，只需在类中添加Meta类
class Meta:
# admin进入以后看到的名字
verbose_name_plural = '博客表'
注册forms类编写
'''forms校验'''
from django import forms
from django.forms import widgets
'''注册校验,写入样式'''
class RegisterForm(forms.Form):
# 名称校验
username = forms.CharField(
max_length=18, min_length=3,label='用户名',
error_messages={'required': '该字段必填', 'max_length': '名字过长,不能超过18个字符',
'min_length': '名字过短,不能少于三个字符'},
widget=widgets.TextInput(attrs={'class': 'form-control'})
)
# 密码校验
password = forms.CharField(
max_length=18, min_length=3,label='密码',

'min_length': '密码过短,不能少于三个字符'},

# 邮箱
email = forms.EmailField(
