fastapi-amis-admin是一个基于fastapi+amis开发的高性能并且高效率 web-admin 框架,使用 Python 3.7+ 并基于标准的 Python 类型提示. fastapi-amis-admin开发的初衷是为了完善fastapi应用生态, 为fastapi web应用程序快速生成一个可视化管理后台.

关键特性

  • 性能极高:基于FastAPI, 可享受FastAPI的全部优势.

  • 效率更快:完善的编码类型提示, 代码可重用性更高.

  • 支持异步和同步混合编写: ORM基于SQLModel+Sqlalchemy, 可自由定制数据库类型, 支持同步及异步模式, 可拓展性强.

  • 前后端分离: 前端由Amis渲染, 后端接口由fastapi-amis-admin自动生成, 接口可重复利用.

  • 可拓展性强: 后台页面支持Amis页面及普通html页面,开发者可以很方便的自由定制界面.

  • 自动生成API文档: 由FastAPI自动生成接口文档,方便开发者调试,以及接口分享.

核心依赖

项目组成

fastapi-amis-admin由三部分核心模块组成,其中amis, crud 可作为独立模块单独使用,admin基于前者共同构建.

  • amis: 基于baidu amispydantic数据模型构建库,用于快速生成/解析amis json 数据.
  • crud: 基于FastAPI+Sqlalchemy, 用于快速构建Create,Read,Update,Delete通用API接口.
  • admin: 启发自Django-Admin, 结合amis+crud, 用于快速构建Web Admin管理后台.

安装

pip install fastapi_amis_admin

注意

  • sqlmodel目前暂不支持sqlalchemy 2.0+, 如果你使用sqlalchemy 2.0+创建模型, 则不可同时使用sqlmodel.
  • fastapi-amis-admin>=0.6.0版本以后,sqlmodel不再是必须依赖库,如果你使用sqlmodel创建模型, 可以通过以下命令安装.
pip install fastapi_amis_admin[sqlmodel]

简单示例

from fastapi import FastAPI
from fastapi_amis_admin.admin.settings import Settings
from fastapi_amis_admin.admin.site import AdminSite

# 创建FastAPI应用
app = FastAPI()

# 创建AdminSite实例
site = AdminSite(settings=Settings(database_url_async='sqlite+aiosqlite:///amisadmin.db'))

# 挂载后台管理系统
site.mount_app(app)

if __name__ == '__main__':
    import uvicorn

    uvicorn.run(app)

模型管理示例

创建模型

  • 支持SQLModel模型的、SQLAlchemy模型、SQLAlchemy 2.0模型
  • 方式一: 通过SQLModel创建模型.
from sqlmodel import SQLModel
from fastapi_amis_admin.models.fields import Field


class Base(SQLModel):
    pass


# 创建SQLModel模型,详细请参考: https://sqlmodel.tiangolo.com/
class Category(SQLModel, table=True):
    id: int = Field(default=None, primary_key=True, nullable=False)
    name: str = Field(title='CategoryName', max_length=100, unique=True, index=True, nullable=False)
    description: str = Field(default='', title='Description', max_length=255)
  • 方式二: 通过SQLAlchemy创建模型.
from sqlalchemy import Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base

Base = declarative_base()


# 创建SQLAlchemy模型,详细请参考: https://docs.sqlalchemy.org/en/14/orm/tutorial.html
class Category(Base):
    __tablename__ = 'category'
    __pydantic_model__ = CategorySchema  # 指定模型对应的Schema类.省略可自动生成,但是建议指定.

    id = Column(Integer, primary_key=True, nullable=False)
    name = Column(String(100), unique=True, index=True, nullable=False)
    description = Column(String(255), default='')
  • 方式三: 通过SQLAlchemy 2.0创建模型.
from sqlalchemy import String
from sqlalchemy.orm import DeclarativeBase, Mapped, mapped_column


class Base(DeclarativeBase):
    pass


# 创建SQLAlchemy 2.0模型,详细请参考: https://docs.sqlalchemy.org/en/20/orm/quickstart.html
class Category(Base):
    __tablename__ = "category"
    __pydantic_model__ = CategorySchema  # 指定模型对应的Schema类.省略可自动生成,但是建议指定.

    id: Mapped[int] = mapped_column(primary_key=True, nullable=False)
    name: Mapped[str] = mapped_column(String(100), unique=True, index=True, nullable=False)
    description: Mapped[str] = mapped_column(String(255), default="")
  • 如果你通过sqlalchemy创建模型,建议同时创建一个对应的pydantic模型,并且设置orm_mode=True.
from pydantic import BaseModel, Field


class CategorySchema(BaseModel):
    id: int = Field(default=None, primary_key=True, nullable=False)
    name: str = Field(title="CategoryName")
    description: str = Field(default="", title="CategoryDescription")

    class Config:
        orm_mode = True

注册模型管理

from fastapi import FastAPI
from sqlmodel import SQLModel
from fastapi_amis_admin.admin.settings import Settings
from fastapi_amis_admin.admin.site import AdminSite
from fastapi_amis_admin.admin import admin

# 创建FastAPI应用
app = FastAPI()

# 创建AdminSite实例
site = AdminSite(settings=Settings(database_url_async='sqlite+aiosqlite:///amisadmin.db'))


# 注册ModelAdmin
@site.register_admin
class CategoryAdmin(admin.ModelAdmin):
    page_schema = '分类管理'
    # 配置管理模型
    model = Category


# 挂载后台管理系统
site.mount_app(app)


# 创建初始化数据库表
@app.on_event("startup")
async def startup():
    await site.db.async_run_sync(Base.metadata.create_all, is_session=False)


if __name__ == '__main__':
    import uvicorn

    uvicorn.run(app)

site = AdminSite(settings=Settings(database_url_async='sqlite+aiosqlite:///amisadmin.db'))


# 注册FormAdmin
@site.register_admin
class UserLoginFormAdmin(admin.FormAdmin):
    page_schema = 'UserLoginForm'
    # 配置表单信息, 可省略
    form = Form(title='这是一个测试登录表单', submitText='登录')

    # 创建表单数据模型
    class schema(BaseModel):
        username: str = Field(..., title='用户名', min_length=3, max_length=30)
        password: str = Field(..., title='密码')

    # 处理表单提交数据
    async def handle(self, request: Request, data: BaseModel, **kwargs) -> BaseApiOut[Any]:
        if data.username == 'amisadmin' and data.password == 'amisadmin':
            return BaseApiOut(msg='登录成功!', data={'token': 'xxxxxx'})
        return BaseApiOut(status=-1, msg='用户名或密码错误!')


# 挂载后台管理系统
