Django进阶三

一、Django Admin的简单用法

1. 　　创建管理员账号

   python manage.py createsuperuser

2. 　　在admin注册我们的表（/project/app01/admin.py）

                       from app01 import models
   admin.site.register(models.类名)
   
   示例：
   from django.contrib import admin
   from app01 import models
   # Register your models hereadmin.site.register(models.Author)
   admin.site.register(models.Publisher)
   admin.site.register(models.Book)

3. 　　其他配置项

   1. admin页面显示中文（settings.py）
       settings.py中修改LANGUAGE_CODE = ‘zh-hans‘
   2. 表名显示中文（models.py）
       类下面写如下配置项
           class Meta:
               verbose_name = "出版社"
               verbose_name_plural = verbose_name
   3. 字段显示中文（models.py）
       address = models.TextField(verbose_name="出版社地址")

4. 　　代码示例
   

                           from django.db import models
   
   
   # Create your models here.class Publisher(models.Model):
       name = models.CharField(max_length=32, unique=True, verbose_name="出版社名称")
       address = models.TextField(verbose_name="出版社地址")
   
       def__str__(self):
           return self.name
   
       class Meta:
           verbose_name = "出版社"
           verbose_name_plural = verbose_name
   
   
   class Author(models.Model):
       name = models.CharField(max_length=12, verbose_name="作者名称")
       gender = models.SmallIntegerField(
           choices=((0, "女"), (1, "男"), (2, "保密")),
           default=2,
           verbose_name="性别"
       )
       age = models.IntegerField(verbose_name="年龄")
   
       def__str__(self):
           return self.name
   
       class Meta:
           verbose_name = "作者管理"
           verbose_name_plural = verbose_name
   
   
   class Book(models.Model):
       title = models.CharField(max_length=32, unique=True, verbose_name="书籍名称")
       # auto_now_add:创建时间  auto_add:修改时间
       publish_date = models.DateField(auto_now_add=True, verbose_name="出版时间")
       phone = models.CharField(max_length=11, unique=True, null=True, blank=True, verbose_name="手机号")
       publisher = models.ForeignKey(to="Publisher", on_delete=models.CASCADE, verbose_name="出版社")
       authors = models.ManyToManyField(to="Author", verbose_name="作者")
   
       def__str__(self):
           return self.title
       
       class Meta:
           verbose_name = "书籍管理"
           verbose_name_plural = verbose_name

二、form和model form:https://www.cnblogs.com/liwenzhou/p/8747872.html

1. 　　form
   1. 　　form的作用

      1. 生成HTML代码
      2. 帮我们做数据有效性的校验
      3. 保留上次输入内容，显示错误提示

      3. 　　form组件校验数据有效性

         1. 内置的校验规则
             1. require=True    该字段必填
             2. max_length      该字段的最大长度
             3. min_length      该字段的最小长度

         2. 自定义校验规则
             1. phone的格式 利用内置的正则校验器
                 from django.core.validators import RegexValidator
                 validators=[RegexValidator(r‘^1[356789]\d{9}$‘, "手机号码格式不正确")],
                 
             2. 手机号的唯一性校验
                 validators=[RegexValidator(r‘^1[356789]\d{9}$‘, "手机号码格式不正确"), phone_validate],
                 
                 # 自定义一个字段的校验规则函数def phone_validate(value):
                     # 拿用户填写的手机号去数据库查找有没有
                     is_exist = models.Book.objects.filter(phone=value)
                     if is_exist:
                         # 如果该手机号已经被使用就不能再注册raise ValidationError("该手机号已经被注册！")
                     else:
                         return value
                                 
                         3. 使用钩子函数做校验
                             1. 局部钩子（hook）
                                 在form类内部定义一个 clean_字段名() 方法
                                 # 自定义一个局部钩子函数def clean_title(self):
                                     value = self.cleaned_data.get("title")
                                     # 判断有没有敏感词if"alex"in value:
                                         raise ValidationError("alex已被河蟹...")
                                     else:
                                         return value
                 
             2. 全局钩子
                 在form类内部定义一个 clean() 方法 
                 # 全局钩子函数def clean(self):
                     # 可以从self.cleaned_data取到所有字段的数据# self.add_error("字段", "密码和确认密码不一致")pass

          

      4. 　　form组合如何给html标签设置默认值

         1. 每一个字段设置默认值
             initial="默认值"

1. 　　model form

   1. 必须继承forms.ModelForm
       class BookModelForm(forms.ModelForm):

   2. class Meta：
       class Meta:
           model = models.Book
           # fields = "__all__"  # model类里所有的字段都展示# fields = ["title", ]  # 指定展示某些字段
           exclude = ["title", ]  # 除了指定字段，其他字段都展示
           labels = {  # 设置label标签名"title": "书名",
               "phone": "手机号",
               "publisher": "出版社",
               "authors": "作者",
           }
           widgets = {  # 设置每个字段的插件信息"title": forms.widgets.TextInput(attrs={"class": "form-control"}),
               "phone": forms.widgets.TextInput(attrs={"class": "form-control"}),
               "publisher": forms.widgets.Select(attrs={"class": "form-control"}),
               "authors": forms.widgets.SelectMultiple(attrs={"class": "form-control"}),
           }
           error_messages = {  # 设置每个字段的报错提示信息"publisher": {
                   "required": "必须给我选一个出版社！"
               }
           }

   3. 实例化
       1. form_obj = BookModelForm()
       2. BookModelForm(instance=book_obj)
       3. BookModelForm(request.POST, instance=book_obj)

   4. 保存 
       form_obj.save()
