How can I use it in graphql?

[amiyatulu]

Is it possible to use it in graphql? https://fastapi.tiangolo.com/advanced/graphql/

Tried this: https://github.com/tiangolo/fastapi/issues/1279

But it's not showing the graphiql ide : {"detail":"Method Not Allowed"}

method not allowed because graphQLFetcher fetch with the same path as graphiql which only supports the get method, I saw from starlette graphql source code

to pass fastapi dependencies you can do this

import graphene
from fastapi import FastAPI, Request, Depends
from fastapi_jwt_auth import AuthJWT
from starlette.graphql import GraphQLApp
from starlette.datastructures import URL
from pydantic import BaseModel

class Settings(BaseModel):
    authjwt_secret_key: str = "secret"

@AuthJWT.load_config
def get_config():
    return Settings()

class Query(graphene.ObjectType):
    hello = graphene.String(name=graphene.String(default_value="stranger"))

    def resolve_hello(self, info, name):
        authorize = info.context['request'].state.authorize
        access_token = authorize.create_access_token(subject=name)
        return "Hello " + name + "access_token" + access_token

app = FastAPI()
graphql_app = GraphQLApp(schema=graphene.Schema(query=Query))

@app.get('/')
async def graphiql(request: Request):
    request._url = URL('/gql')
    return await graphql_app.handle_graphiql(request=request)

@app.post('/gql')
async def graphql(request: Request, authorize: AuthJWT = Depends()):
    request.state.authorize = authorize
    return await graphql_app.handle_graphql(request=request)

I'm sorry if my explanation is bad cause I never use graphql, I hope this can answer your question 😄

[amiyatulu]

Thank you. Its working.

[IndominusByte]

Glad to hear that 😄 🙏

hi @IndominusByte , was wondering if I could get your 2 cents? I modified the above example for database connections.

import fastapi
import uvicorn

import graphene
from fastapi import FastAPI, Request, Depends
from starlette.graphql import GraphQLApp
from starlette.datastructures import URL
from pydantic import BaseModel

from app.api import deps
from sqlalchemy.orm import Session

app = fastapi.FastAPI()

class Query(graphene.ObjectType):
    hello = graphene.String(name=graphene.String(default_value="stranger"))

    def resolve_hello(self, info, name):
        db = info.context['request'].state.db
        return f"hi {name}, db active {db.is_active}"

app = FastAPI()
graphql_app = GraphQLApp(schema=graphene.Schema(query=Query))

@app.get('/')
async def graphiql(request: Request):
    request._url = URL('/gql')
    return await graphql_app.handle_graphiql(request=request)

@app.post('/gql')
async def graphql(request: Request, db: Session = Depends(deps.get_db)):
    request.state.db = db
    return await graphql_app.handle_graphql(request=request)
