Does anyone have an example of how to access params passed at the CLI in a hook? I know this isn't a very Kedronic pattern, but it seems a necessary workaround for my use case

I’d argue it is Kedriffic! The params should be in the
extra_params
attr of the
before_pipeline_run
hook

I'll add that one to my vocabulary! Do you have any thoughts about if this will work if I'm trying to dynamically generate catalog entries? I think what I really need is to be able to override globals from the CLI, something like this:
Copy code
${<http://globals.site|globals.site>}_${globals.service}_usage:
  type: pandas.SQLQueryDataSet
  filepath: data/01_raw/${globals.service}.sql
  load_args:
    index_col: "my_index_col"
    params:
      start_date: ${globals.start_date}
      end_date: ${globals.end_date}
  credentials: ${globals.site.db_creds}
  layer: Raw
But as I understand, this isn't currently possible with catalog templating. Dynamically generating the catalog at runtime via hooks seems like the next best option.

You can do it with a omega conf resolver

Thanks, I'll look into this!
@datajoely So am I right in saying that this can now (as of
0.18.13
) be done right from
settings.py
? Something like:
Copy code
CONFIG_LOADER_ARGS = {
    "custom_resolvers": {
        "runtime_param": lambda x: self.runtime_params[x],
    }
}
Though I don't understand the OmegaConf implementation well enough to know the correct syntax here, surely
self
is not right

hey let me look into this
They create a new config loader class which is how they can use self

Oh yeah I saw this, but I wasn't sure where
ExtendedOmegaConfigLoader
was implemented (within
settings.py
?) or what the contents of
register_custom_resolver
was supposed to be!

it can be anywhere you just need to import it into setting.py and use it under
CONFIG_LOADER_CLASS

Cheers, that makes sense! It would be good to know what's going on in that static method 🤔

@Jordan Barlow Did this end up working for you? OmegaConf looks undefined to me in the static method above. @Fazil B. Topal @datajoely any help appreciated. Edit: nvm was being silly. Just had to import OmegaConf from omegaconf. Sorry for the pings.
