海外TECH	DEV Community	The Best Practice of handling FastAPI Schema	https://dev.to/gyudoza/the-best-practice-of-handling-fastapi-schema-2g3a	The Best Practice of handling FastAPI Schema The Best Practice of handling FastAPI SchemaFastAPI Has a concept of Schema DTO is more familiar name If you have developed at Spring or NestJS Simply DTO is Data Transfer Object and It is a kind of promise to exchange object information between methods or classes in a specific model FastAPI s schema depends on pydantic model from pydantic import BaseModelclass Item BaseModel name str model str manufacturer str price float tax floatAs you can see schema is made by inheriting the pydantic Base Model Now let s use this to construct an api endpoint from fastapi import FastAPIfrom pydantic import BaseModelapp FastAPI class Item BaseModel name str model str manufacturer str price float tax float app get async def root item Item return message Hello World If you declare that you re gonna get an item schema at the basic endpoint In this way an example of receiving the model is automatically generated You can use this in other ways likefrom fastapi import FastAPI Dependsfrom pydantic import BaseModelapp FastAPI class Item BaseModel name str model str manufacturer str price float tax float app get async def root item Item Depends return message Hello World If you register the value Depends at schema You can see that the part that you want to receive as a Body has changed to Parameter Doesn t it feel like You ve seen it somewhere Right It is a common method for constructing search query However as can be seen above it can be seen that there is a limit of required values It s a search query but it doesn t make sense that all members have a required option So it is necessary to change all of this to optional very easilyfrom pydantic import BaseModelfrom typing import Optionalclass Item BaseModel name Optional str model Optional str manufacturer Optional str price Optional float tax Optional float It can be made in this way but if the default value of the schema members are optional there is a hassle of removing all the Optional when configuring the PUT method endpoint later Oh it is recommended that anyone who has no clear distinction between the PUT method and the PATCH method here refer to this article In short PUT is the promised method of changing the total value of an element and PATCH is the method of changing some So I use this way from pydantic main import ModelMetaclassclass AllOptional ModelMetaclass def new self name bases namespaces kwargs annotations namespaces get annotations for base in bases annotations update base annotations for field in annotations if not field startswith annotations field Optional annotations field namespaces annotations annotations return super new self name bases namespaces kwargs This class has the function of changing all member variables of the class to Optional when declared as metaclass from fastapi import FastAPI Dependsfrom pydantic import BaseModelfrom pydantic main import ModelMetaclassfrom typing import Optionalapp FastAPI class AllOptional ModelMetaclass def new self name bases namespaces kwargs annotations namespaces get annotations for base in bases annotations update base annotations for field in annotations if not field startswith annotations field Optional annotations field namespaces annotations annotations return super new self name bases namespaces kwargs class Item BaseModel name str model str manufacturer str price float tax floatclass OptionalItem Item metaclass AllOptional pass app get async def root item OptionalItem Depends return message Hello World If you inherit the class made of the pydantic Base Model and declare metaclass AllOptional there You can see Parameters without required option However when dealing with a schema in practice there are things that are not needed when putting it in and necessary when bringing it later It is common for id created datetime updated datetime etc And sometimes you have to remove some members and show them In spring or nest you can flexibly cope with this situation by using the setFieldToIgnore function or the Omit class but as anyone who has dealt with FastAPI can see there are no such things So after a lot of trial and error i established a way of using FastAPI schema like the DTO we used before It would be irrelevant to say that this is the best practice now Why I looked up numerous examples but there was no perfect alternative so I defined them myself and made them This is an example using the schema called Item used above from pydantic import BaseModelclass BaseItem BaseModel name str model str manufacturer str price float tax floatThe most basic members are defined as BaseItem It can be seen as defining the elements used in Upsert The pydantic model will basically be a schema used in the PUT method because it will be treated as Required if it is not set as Optional or None class Item BaseItem metaclass AllOptional id int created datetime datetime updated datetime datetimeIt is an item that inherits BaseItem Even if the class inherited the Base Model is inherited the inherited class also becomes a pydantic model so it can be declared this simply It is used to throw items that are not used in Upsert including basic elements This is a schema mainly used to inquire items so wouldn t it be okay not to attach Optional But if there is a non Optional member and its value has no Value an error is occurred class FindBase BaseModel count int page int order strclass FindItem FindBase BaseItem metaclass AllOptional passParameters used to find items can be declared in this way It inherits the BaseItem and FindBase declared above and treats them both as options with metaclass AllOptional to remove the required option of the parameter And lastly class Omit ModelMetaclass def new self name bases namespaces kwargs omit fields getattr namespaces get Config omit fields fields namespaces get fields annotations namespaces get annotations for base in bases fields update base fields annotations update base annotations merged keys fields keys amp annotations keys merged keys add field for field in fields new fields new annotations for field in merged keys if not field startswith and field not in omit fields new annotations field annotations get field fields field type new fields field fields field namespaces annotations new annotations namespaces fields new fields return super new self name bases namespaces kwargs This is a metaclass that supports the Omit function I needed it but I couldn t find it so I made it class BaseItem BaseModel name str model str manufacturer str price float tax floatclass OmittedTaxPrice BaseItem metaclass Omit class Config omit fields tax price If you declare omit fields in class Config in this way you can get a new schema with removed fields ※And one thing to note is that metaclass is executed every time a class is created so only one class involved in an inheritance relationship can be declared For exampleclass BaseItem BaseModel name str model str manufacturer str price float tax floatclass Item BaseItem metaclass AllOptional id int created datetime datetime updated datetime datetimeclass TestItem Item additional number intIf the Item declared metaclass AllOptional is inherited from TestItem AllOptional is executed twice Once when creating an Item class once again when creating a TestItem that inherits the Item Therefore the additional number a member variable of TestItem that inherits the Item is also Optional That is metaclass So if you declare another metaclass like Omit the program is broken class TestItem Item metaclass AllOptional pass TypeError metaclass conflict the metaclass of a derived class must be a non strict subclass of the metaclasses of all its bases So it is good to declare and use metaclass in the last inheritance class before it is used as schema This makes easy to recognize its function Anyway if you use the above mentioned four http methods GET POST PUT and PATCH which are often used it consists of this It can also be found in my git repo from datetime import datetimefrom fastapi import FastAPI Dependsfrom pydantic import BaseModelfrom pydantic main import ModelMetaclassfrom typing import Optional Listapp FastAPI class

return hello world app put items id response model Item async def put item id int schema BaseItem return hello world app get items omitted response model OmittedTaxPrice async def omitted item schema OmittedTaxPrice return hello world When configured in this way the following swagger documents are generated find items endpoint with optional parameters create item Put methodIf you omit the item name according to the usage of PUT METHOD error is returned to send it with some name The PUT was formed by declaring that it would receive BaseItem as a body PATCH method OmittedIn this way we learned how to deal with FastAPIschema If you use something you may see more necessary functions but the endpoint and docs configuration that you need this much is progressing without difficulty in my case If you want to actively use FastAPI s schema to write docs please refer to it to reduce trial and error	2022-02-19 09:37:49
