To pass a variable from a FastAPI route to another class, you can simply instantiate the class and pass the variable as an argument to a method or a constructor of the class. Here is an example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
from fastapi import FastAPI
from pydantic import BaseModel
from typing import List
app = FastAPI()
class SomeClass:
def do_something(self, variable):
print(f"Received variable: {variable}")
# Do something with the variable
some_instance = SomeClass()
class Item(BaseModel):
name: str
@app.post("/items/")
async def create_item(item: Item):
some_instance.do_something(item.name)
return {"name": item.name}
|
In this example, the /items/ route receives an Item object, extracts the name attribute, and passes it to the do_something method of the SomeClass instance. You can modify the example according to your requirements and structure of your code.
