 ## Get an asset's ID
 
-You can get an asset's ID by using it's URL:
+If the asset URL starts with `/media`, the asset ID is in the URL.
+For example, for the URL `https://assets.publishing.service.gov.uk/media/65f2c1110e1c2f8c4dffaa53/my_file.jpg`, the ID is `65f2c1110e1c2f8c4dffaa53`.
 
-1. Open a Rails console:
+For assets that do not start `/media`, obtain the ID by running the following rake task:
 
-    ```sh
-    k exec -it deploy/asset-manager -- rails c
-    ```
+<%= RunRakeTask.links("asset-manager", "assets:get_id_by_legacy_url_path[SLUG]") %>
 
-2. Find the asset:
-
-    ```ruby
-    asset = Asset.find_by(legacy_url_path: "/slug")
-    id = asset.id
-    ```

-    For example, if the URL is
-
-    ```
-    https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1234/document.pdf
-    ```
-
-    the slug would be `/government/uploads/system/uploads/attachment_data/file/1234/document.pdf`
+For example, for `https://assets.publishing.service.gov.uk/government/uploads/uploaded/hmrc/realtimepayetools-update-v23.xml"`, you would pass `/government/uploads/uploaded/hmrc/realtimepayetools-update-v23.xml` as the argument.
