I have this method to run an asset.

def materialize_those_assets():
    materialize([AssetKey("your_asset_name")])
    print("Asset materialization completed.")

how to change it in order to pass a list of methods defined with asset decorator

my_asset_list = [asset_1, asset_2, asset_3]
materialize_those_assets(my_asset_list)

how to retrieve the AssetKey properly and make the materialization works?

To materialize a list of assets defined with the

@asset

decorator, you need to retrieve the

AssetKey

for each asset and pass them to the

materialize

function. The

AssetKey

is typically derived from the name of the asset function or can be explicitly defined using the

key_prefix

and

name

parameters in the

@asset

decorator. Here's how you can modify your

materialize_those_assets

function to accept a list of asset functions and materialize them:

python from dagster import AssetKey, materialize  def materialize_those_assets(asset_list):     asset_keys = [AssetKey(asset.__name__) for asset in asset_list]     materialize(asset_keys)     print("Asset materialization completed.")  # Assuming asset_1, asset_2, and asset_3 are defined with the @asset decorator my_asset_list = [asset_1, asset_2, asset_3] materialize_those_assets(my_asset_list)

In this code snippet, we assume that the asset functions are named

asset_1

,

asset_2

, and

asset_3

, and we use the

__name__

attribute of the function to construct the

AssetKey

. If you have defined a custom asset key using the

key_prefix

argument in the

@asset

decorator, you would need to construct the

AssetKey

accordingly. For example, if

asset_1

is defined with a custom key prefix like this:

python from dagster import asset  @asset(key_prefix=["my", "custom", "prefix"]) def asset_1():     # Asset computation logic     pass

You would need to construct the

AssetKey

using the same prefix:

python AssetKey(["my", "custom", "prefix", "asset_1"])

Please adjust the

AssetKey

construction in the

materialize_those_assets

function based on how you have defined your asset keys. If you have used a different naming convention or key structure, you will need to modify the

AssetKey

creation accordingly.
