| 95 | The | In Datasette 0.x plugins could implement a get_metadata() plugin hook to customize how metadata was retrieved for different instances, databases and tables. This hook could be inefficient, since some pages might load metadata for many different items (to list a large number of tables, for example) which could result in a large number of calls to potentially expensive plugin hook implementations. As of Datasette 1.0a14 (2024-08-05), the get_metadata() hook has been deprecated: # ❌ DEPRECATED in Datasette 1.0 @hookimpl def get_metadata(datasette, key, database, table): pass Instead, plugins are encouraged to interact directly with Datasette's in-memory metadata tables in SQLite using the following methods on the Datasette class : get_instance_metadata() and set_instance_metadata() get_database_metadata() and set_database_metadata() get_resource_metadata() and set_resource_metadata() get_column_metadata() and set_column_metadata() A plugin that stores or calculates its own metadata can implement the startup(datasette) hook to populate those items on startup, and then call those methods while it is running to persist any new metadata changes. |
