Getting stuck trying to use assets. I have one file that generates assets:

assets_list = []
for ii in [1, 2, 3]:
    @asset(name=["my_asset", f"model_{ii}"])
    def _generated_asset():
        return ii
    assets_list.append(_generated_asset)

and i want to reference it in another file

from .asset_list_file import assets_list

asset_1 = assets_list[0]
asset_2 = assets_list[1]

@asset
def my_downstream_asset(asset_1, asset_2):
    return asset_1 + asset_2

But I'm getting a variety of errors related to

asset_1

not being created, etc. I've tried creating new

SourceAssetes

that reference the assets in the first file. The cross-repository example here seems to be what I want, but I can't directly import the AssetDefinition, because it's being dynamically generated. Its just really unclear to me what the relationship is between asset keys, the input arguments for assets, how to do AssetSelections. It seems like there's some under-the-hood relationship between the variable name and the inputs. Is there a recommended way for me to approach this problem?

hey @Stephen Bailey - glad you were able to figure it out. there are a couple things going on here: • the input matching is based on the asset key/name, not the variable name. so this should work:

assets_list = []
for ii in [1, 2, 3]:
    @asset(name="model_{ii}")
    def _generated_asset():
        return ii
    assets_list.append(_generated_asset)

@asset
def my_downstream_asset(model_1, model_2):
    return model_1 + model_2

• when an has a multi-segment key, like in your case, you need to use `AssetIn`s

gotcha, thanks. it was a little confusing because in the ui, it appears that you can reference the multi-part asset keys by joining with

__

like

my_asset__model_1

, but that doesn't appear to be the case
