Hey! Is there a way to pass a path (or similar) from an asset materialization config to the

ins

parameter? My specific case is passing a google sheet URL to an asset and having an io manager read it in as a pandas DataFrame. This was how I imagined it might look but, it raises a code location error that

AttributeError: 'In' object has no attribute 'key'

.

@asset(
    io_manager_key="gsheets_io",
    config_schema={
        "input_url": str,
    },
    ins={
        "df": In(
            input_manager_key="gsheets_io",
            asset_key=lambda context: AssetKey([context.config["input_url"]]),
        )
    },
)
def asset_fn(context, df):
    ...

Hi @Guy McCombe does the

input_url

need to change between materializations of the asset?

That was the plan, yep

ok. You may want to use an op for this instead. Basically an asset is supposed to represent like a single dataset stored in the same location. You might add to that dataset over time, but the location where the data is stored doesnt change. If you use an op you can provide configuration values via op config You could also look into generating assets in a factory function based on the user input. if that sounds more like what you need i can write up some pseudocode

OK I’ll give these a look, thanks jamie 😃

yep!
