Installation

pip install sanic-dantic

Why use it

Do you have to get the request parameters first every time you process them ?

from sanic import Sanic
from sanic.response import json

app = Sanic("SanicDanticExample")


@app.route('/example')
async def path_param_examples(request):
    name = request.get("name")
    age = request.get("age")
    if not isinstance(name, str) or not isinstance(age, int):
        return json({"error": "parameter type error"})
    return json({"message": f"hello {name} are you {age} years old ?"})

How terrible, and there is no good experience for developers at all.

Therefore, sanic-dantic is to help you improve your development efficiency and experience.

It allows you to skip the process of type checking and parameter acquisition.

How to use

It is based on pydantic, which can facilitate developers to quickly check and obtain request parameters

In sanic-dantic, you can pass the pydantic model to different formal parameters in parse_params to check and parse the values of different types of request parameters

You can get all the parsed parameters by appending the formal parameter , and get the value of the parameter through the attribute params

from sanic import Sanic
from sanic.response import json

from sanic_dantic import parse_params, BaseModel


class Person(BaseModel):
    name: str
    age: int


app = Sanic("SanicDanticExample")


@app.route('/example')
@parse_params(path=Person)
async def path_param_examples(request, params):
    print(params.ctx.name, params.ctx.age)
    return json(
        {"message": f"hello {params.name} are you {params.age} years old ?"})
