Dynamic Python Function Generation from GraphQL Schema for API Requests

[b8511]

I'm looking for a method to dynamically generate Python functions that correspond to the queries and mutations defined in a GraphQL schema. After obtaining the schema, I want a system that can automatically create these functions, so I can simply import the generated code into my Python project and call the functions with the necessary parameters.

The ideal solution would facilitate seamless interactions with the GraphQL API by abstracting the request construction process. It would allow for changes in the schema without the need for manual updates to the function definitions in the client code.

I haved tried ariadnegraphql code generator but I had to specify a query like this:

query MyQuery {
getCar(plate_number: "14-77-ER") {
addresses
brand
mongoObjId
}
}
and it created an Client for this query with fix params.

Any advice on how I can better leverage the capabilities of Ariadne would be awesome!

Hello!

This is exactly what Ariadne Codegen does. It takes schema, GraphQL queries and generates fully typed client class you import in your code to run queries.

Alright, maybe I'm not understanding what is the use for queries_path, cause I just put an example of one of my queries in the file that queries_path is pointing to
like so:
query MyQuery {
getCar(plate_number: "14-77-ER") {
addresses
brand
mongoObjId
}
}

and got client.py file like this:
`

Generated by ariadne-codegen

Source: queries.graphql

from typing import Any, Dict

from .async_base_client import AsyncBaseClient
from .my_query import MyQuery

def gql(q: str) -> str:
return q

class Client(AsyncBaseClient):
async def my_query(self, **kwargs: Any) -> MyQuery:
query = gql(
"""
query MyQuery {
getCar(plate_number: "14-77-ER") {
addresses
brand
mongoObjId
}
}
"""
)
variables: Dict[str, object] = {}
response = await self.execute(query=query, variables=variables, **kwargs)
data = self.get_data(response)
return MyQuery.model_validate(data)
`

I wanted to not have a fixed param in the plate_number

You need to change your query to accept variable:

query MyQuery($plate: String!) {
  getCar(plate_number: $plate) {
    addresses
    brand
    mongoObjId
  }
}

Then generated client will have a my_query(plate: string) method.

It work. Lets Go! Sry for my ignorance

[b8511]

Is there a way to make queries.graphql automatically?

[rafalp]

Nope, GraphQL is too open standard for this to make a sense.

But you can try implementing such solution yourself through a plugin.

alright, anyways thank you for your time
