Introduction

fastapi-amis-admin is a high-performance and efficient framework based on fastapi & amis with Python 3.7+, and based on standard Python type hints. The original intention of the development is to improve the application ecology and to quickly generate a visual dashboard for the web application . According to the Apache2.0 protocol, it is free and open source . But in order to better operate and maintain this project in the long run, I very much hope to get everyone's sponsorship and support.

Features

• High performance: Based on FastAPI. Enjoy all the benefits.
• High efficiency: Perfect code type hints. Higher code reusability.
• Support asynchronous and synchronous hybrid writing: ORM is based onSQLModel & Sqlalchemy. Freely customize database type. Support synchronous and asynchronous mode. Strong scalability.
• Front-end separation: The front-end is rendered by Amis, the back-end interface is automatically generated by fastapi-amis-admin. The interface is reusable.
• Strong scalability: The background page supports Amis pages and ordinary html pages. Easily customize the interface freely.
• Automatic api documentation: Automatically generate Interface documentation by FastAPI. Easily debug and share interfaces.

Dependencies

• FastAPI: Finish the web part.
• SQLModel: Finish ORM model mapping. Perfectly combine SQLAlchemy with Pydantic, and have all their features .
• Amis: Finish admin page presentation.

Composition

fastapi-amis-admin consists of three core modules, of which, amis, crud can be used as separate modules, admin is developed by the former.

• amis: Based on the pydantic data model building library of baidu amis. To generate/parse data rapidly.
• crud: Based on FastAPI &Sqlalchemy. To quickly build Create, Read, Update, Delete common API interface .
• admin: Inspired by Django-Admin. Combine amis with crud. To quickly build Web Admin dashboard .

Installation

pip install fastapi_amis_admin

Note

• After version fastapi-amis-admin>=0.6.0, sqlmodel is no longer a required dependency library. If you use sqlmodel to create a model, you can install it with the following command.

pip install fastapi_amis_admin[sqlmodel]

Simple Example

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

# create FastAPI application
app = FastAPI()

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

# mount AdminSite instance
site.mount_app(app)

if __name__ == '__main__':
    import uvicorn

    uvicorn.run(app)

ModelAdmin Example

Create Model

• Support SQLModel model, SQLAlchemy model, SQLAlchemy 2.0 model
• Method 1: Create model through SQLModel.

from typing import Optional
from sqlmodel import SQLModel
from fastapi_amis_admin.models.fields import Field


class Base(SQLModel):
    pass


# Create an SQLModel, see document for details: https://sqlmodel.tiangolo.com/
class Category(SQLModel, table=True):
    id: Optional[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)

• Method 2: Create model through SQLAlchemy.

from sqlalchemy import Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base

Base = declarative_base()


# Create an SQLAlchemy model, see document for details: https://docs.sqlalchemy.org/en/14/orm/tutorial.html
class Category(Base):
    __tablename__ = 'category'
    # Specify the Schema class corresponding to the model. It is recommended to specify it. If omitted, it can be automatically generated.
    __pydantic_model__ = CategorySchema

    id = Column(Integer, primary_key=True, nullable=False)
    name = Column(String(100), unique=True, index=True, nullable=False)
    description = Column(String(255), default='')

• Method 3: Create model through SQLAlchemy 2.0.

from sqlalchemy import String
from sqlalchemy.orm import DeclarativeBase, Mapped, mapped_column


class Base(DeclarativeBase):
    pass


# Create an SQLAlchemy 2.0 model, see document for details: https://docs.sqlalchemy.org/en/20/orm/quickstart.html
class Category(Base):
    __tablename__ = "category"
    # Specify the Schema class corresponding to the model. It is recommended to specify it. If omitted, it can be automatically generated.
    __pydantic_model__ = CategorySchema

    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="")

• If you create a model through sqlalchemy, it is recommended to create a corresponding pydantic model at the same time, and set orm_mode=True.

from pydantic import BaseModel, Field


class CategorySchema(BaseModel):
    id: Optional[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

Register ModelAdmin

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

# create FastAPI application
app = FastAPI()

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


# register ModelAdmin
@site.register_admin
class CategoryAdmin(admin.ModelAdmin):
    page_schema = 'Category'
    # set model
    model = Category


# mount AdminSite instance
site.mount_app(app)


# create initial database table
@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)

FormAdmin Example

from typing import Any
from fastapi import FastAPI
from pydantic import BaseModel
from starlette.requests import Request
from fastapi_amis_admin.amis.components import Form
from fastapi_amis_admin.admin import admin
from fastapi_amis_admin.admin.settings import Settings
from fastapi_amis_admin.admin.site import AdminSite
from fastapi_amis_admin.crud.schema import BaseApiOut
from fastapi_amis_admin.models.fields import Field

# create FastAPI application
app = FastAPI()

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


# register FormAdmin
@site.register_admin
class UserLoginFormAdmin(admin.FormAdmin):
    page_schema = 'UserLoginForm'
    # set form information, optional
    form = Form(title='This is a test login form', submitText='login')

    # create form schema
    class schema(BaseModel):
        username: str = Field(..., title='username', min_length=3, max_length=30)
        password: str = Field(..., title='password')

    # handle form submission data
    async def handle(self, request: Request, data: BaseModel, **kwargs) -> BaseApiOut[Any]:
        if data.username == 'amisadmin' and data.password == 'amisadmin':
            return BaseApiOut(msg='Login successfully!', data={'token': 'xxxxxx'})
        return BaseApiOut(status=-1, msg='Incorrect username or password!')


# mount AdminSite instance
site.mount_app(app)

if __name__ == '__main__':
    import uvicorn

    uvicorn.run(app)
