FastApi add ability to edit post?

Question

Python

We need to add the ability to change the post

from typing import Optional

from fastapi import FastAPI, HTTPException
from fastapi.encoders import jsonable_encoder
from pydantic.dataclasses import dataclass

app = FastAPI()

@dataclass
class Post:
id: int
header: str
content: str

@dataclass
class CreatePost :
header: str
content: str

@dataclass
class UpdatePost:
id: int
header: str
content: str

posts: list[Post] = [
Post(id=1, header="Python", content="some text about Python") ,
Post(id=2, header="JavaScript", content="some text about JavaScript")
]

@app.get("/api/posts")
def get_posts():
return posts

@app.get("/api/ posts/{id}")
def get_post(id: int):
for post in posts:
if post.id == id:
return post
raise HTTPException(status_code=404)

@app.post("/api/posts")
def create_post(post: CreatePost):
global posts
id = posts[-1].id + 1
post = Post(id=id, header=post.header, content=post.content)
posts.append(post)
return post

@app .delete("/api/posts/{id}")
def delete_post(id: int):
global posts
for i in range(len(posts)):
if posts[i].id == id:
return posts.pop(i)
raise HTTPException(status_code=404)

Answer 1

you make a PATCH method handler, as a parameter in the url you pass id as in DELETE, for example, and in the body of the request you pass JSON with the fields that need to be changed, and then, look for the desired post by id, change its fields from the received JSON, well, you can return the changed record in case of success, as an option. all
