airflow.providers.google.cloud.hooks.vision.ERR_DIFF_NAMES = Multiline-String[source]
Show Value
1The {label} name provided in the object ({explicit_name}) is different
2    than the name created from the input parameters ({constructed_name}). Please either:
3    1) Remove the {label} name,
4    2) Remove the location and {id_label} parameters,
5    3) Unify the {label} name and input parameters.
airflow.providers.google.cloud.hooks.vision.ERR_UNABLE_TO_CREATE = Multiline-String[source]
Show Value
1Unable to determine the {label} name. Please either set the name directly
2    in the {label} object or provide the `location` and `{id_label}` parameters.
class airflow.providers.google.cloud.hooks.vision.NameDeterminer(label, id_label, get_path)[source]

Helper class to determine entity name.

get_entity_with_name(self, entity, entity_id, location, project_id)[source]

Check if entity has the name attribute set: * If so, no action is taken.

  • If not, and the name can be constructed from other parameters provided, it is created and filled in

    the entity.

  • If both the entity’s ‘name’ attribute is set and the name can be constructed from other parameters

    provided:

    • If they are the same - no action is taken

    • if they are different - an exception is thrown.

Parameters

  • entity (Any) – Entity

  • entity_id (Optional[str]) – Entity id

  • location (Optional[str]) – Location

  • project_id (str) – The id of Google Cloud Vision project.

Returns

The same entity or entity with new name

Return type

str

Raises

AirflowException
