Hi all I have a yaml file: parameters/modules/basic.yml

general.Basic:
   asset_key: asset_id

Now I want to use value of

asset_key

in other yaml file: parameters/modules/capacity.yml

general.Basic:
   capacity_key: ${basic:general.Basic.asset_key}

So I define in settings.py:

CONFIG_LOADER_ARGS = {
    "config_patterns": {
        "basic": ["**/basic.yml"],
        "catalog": ["catalog*", "catalog*/**", "../catalog*", "../catalog*/**"],
        "parameters": ["parameters*", "parameters*/**", "**/parameters*"],
        "modules": [
            "parameters/modules*",
            "parameters/modules*/**",
        ],
        "credentials": ["credentials*", "credentials*/**", "**/credentials*"],
        "logging": ["logging*", "logging*/**", "**/logging*"],
    },
}

However, I keep getting an interpolation error. From the docs I have understood that this should be possible, using the approach described above.

${basic:general.Basic.asset_key}

This is an incorrect key

The PR is still up @Nok Lam Chan https://github.com/kedro-org/kedro/pull/4092

you're right😅sorry I have looked at too many PR today

Thanks guys!

I don’t understand what are the config_patterns you are using, they are all just parameters right? If so you can remove the basic and module from there.

Yeah, exactly this seems to be the issue, OmegaConfLoader interprets

general.Basic.asset_key

as

"general": {
  "Basic": {
      "asset_key: {}
   }
}
