Django 框架快速使用扩展库

【阅读文档】

本项目在以下代码托管网站同步更新:

安装与升级

目前 Django Cool 支持的 Python 环境有 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13 支持 Django 版本 2.2, 3.x, 4.x, 5.x

为了简化安装过程,推荐使用 pip 进行安装

pip install django-cool

升级 Django Cool 到新版本:

pip install -U django-cool

如果需要安装 GitHub 上的最新代码:

pip install https://github.com/007gzs/django-cool/archive/master.zip

如果需要展示html接口文档需要安装markdown依赖:

pip install markdown

如果使用websocket功能需要安装channels依赖:

pip install channels>=2.4

开始使用

settings.py 配置

INSTALLED_APPS 中添加 cool

INSTALLED_APPS = (
    ...
    'cool',
)

settings.py 中设置 DJANGO_COOL

DJANGO_COOL = {
    'API_ERROR_CODES': (
        ('ERR_DEMO_NOLOGIN', (10001, '请先登陆')),
        ('ERR_DEMO_NOTFOUND', (10002, '用户名密码错误')),
        ('ERR_DEMO_PERMISSION', (10003, '权限错误')),
        ('ERR_DEMO_DUPLICATE_USERNAME', (10011, '用户名已存在')),
        ('ERR_DEMO_DUPLICATE_MOBILE', (10012, '手机号已存在')),
    )
}

models扩展

自定义 Model 继承 BaseModel 可使用扩展功能:

  • 支持字段变更监控记录
    • 通过 save_changed() 保存已修改字段

  • 主键唯一键缓存
    • 缓存获取: get_obj_by_pk_from_cache() get_obj_by_unique_key_from_cache()

    • 删除缓存: flush_cache_by_pk() flush_cache_by_unique_key() flush_cache()

  • 搜索字段自动生成
    • get_search_fields() 自动生成搜索字段,默认返回所有设置索引的char和int类型字段

后台管理扩展

BaseModelAdmin 提供扩展功能:

  • 默认列出所有基础字段

  • 增加相关项列,通过外键快速跳转

  • 增、删、改权限统一控制

  • 提交保存时,检查数据是否被修改

使用 admin_register() 装饰器可以快速将 Model 注册到后台管理

@admin_register
class Module(BaseModel):
    name = models.CharField('module name', max_length=255)
    code = models.CharField('module code', max_length=100, unique=True)


@admin_register(
    list_display=['module', 'name'],
    list_filter=['module', ],
    change_view_readonly_fields=['code', ],
    list_editable=['name', 'module']
)
class Permission(BaseModel):
    name = models.CharField('permission name', max_length=255)
    code = models.CharField('permission code', max_length=100)
    module = model.ForeignKey(
        Module, verbose_name='module', to_field='code', db_column='module_code', on_delete=models.PROTECT
    )

api接口扩展

  • CoolBFFAPIView 可方便创建 application/x-www-form-urlencoded / multipart/form-data 方式的接口。

  • Meta 类中配置参数列表 param_fields 后可以自动生成接口文档,自动做参数验证

  • 使用 ViewSite 快速注册接口生成 urlpatterns

使用样例:

views.py:

from cool.views import ViewSite, CoolBFFAPIView, ErrorCode, CoolAPIException
from django.contrib.auth import authenticate, login
from django.db import IntegrityError
from django.db.models import Q
from rest_framework import fields

from . import serializer, constants

site = ViewSite(name='demo', app_name='demo')


@site
class UserRegister(CoolBFFAPIView):

    name = '用户注册'
    response_info_serializer_class = serializer.UserSerializer

    def get_context(self, request, *args, **kwargs):
        user = models.User.objects.filter(
            Q(username=request.params.username) | Q(mobile=request.params.mobile)
        ).first()
        if user is not None:
            if user.username == request.params.username:
                raise CoolAPIException(ErrorCode.ERR_DEMO_DUPLICATE_USERNAME)
            elif user.mobile == request.params.mobile:
                raise CoolAPIException(ErrorCode.ERR_DEMO_DUPLICATE_MOBILE)
        user = models.User()
        user.username = request.params.username
        user.mobile = request.params.mobile
        user.nickname = request.params.nickname
        user.name = request.params.name
        user.avatar = request.params.avatar
        user.gender = request.params.gender
        user.set_password(request.params.password)
        try:
            user.save(force_insert=True)
        except IntegrityError as exc:
            if exc.args[0] == 1062:
                if exc.args[1].find('username') >= 0:
                    exc = CoolAPIException(ErrorCode.ERR_DEMO_DUPLICATE_USERNAME)
                elif exc.args[1].find('mobile') >= 0:
                    exc = CoolAPIException(ErrorCode.ERR_DEMO_DUPLICATE_MOBILE)
            raise exc
        user = authenticate(self, base_username=request.params.username, base_password=request.params.password)
        if user is None:
            raise CoolAPIException(ErrorCode.ERR_DEMO_NOTFOUND)
        login(request, user)
        return serializer.UserSerializer(user, request=request).data

    class Meta:
        param_fields = (
            ('username', fields.CharField(label='登陆名', max_length=64, help_text='字段说明,会显示在接口文档中')),
            ('password', fields.CharField(label='密码'),
            ('gender', fields.ChoiceField(label='性别', choices=constants.Gender.get_choices_list())),
            ('mobile', fields.RegexField(r'1\d{10}', label='手机号')),
            ('nickname', fields.CharField(label='昵称', max_length=255)),
            ('name', fields.CharField(label='姓名', default='', max_length=255)),
            ('avatar', fields.ImageField(label='头像', default=None)),
        )


urls = site.urls
urlpatterns = site.urlpatterns

urls.py:

from django.contrib import admin
from django.urls import path, include
from cool.views import get_api_doc_html


api_patterns = [
    path('demo/', include('example.apps.demo.views')),
]
urlpatterns = [
    path('cool/', include('cool.urls')),
    path('admin/', admin.site.urls),
    path('api/', include(api_patterns)),
    path('api_doc.html', get_api_doc_html)
]
