# xpressinsight.AppInterface.get_attachs_by_tag

Purpose

Gets Insight attachments by tag.

Searches the scenario and the containing app for an attachment or attachments with the given tag, and retrieves them from the Insight server, placing them in a local directory where they can be read by the model. If any scenario attachments with the given tag are found, these are retrieved without searching the app. If no scenario attachments with the given tag are found, then the search continues at the app level.

Synopsis
`xpressinsight.AppInterface.get_attachs_by_tag(self, tag: str, *, destination_directory: str = None) -> Optional[List[Attachment]]`
Arguments

tag | The tag to search for
destination_directory | The directory into which to copy the attachments, which must exist or a FileNotFoundError will be raised. If not specified, the attachments will be copied into the Python working directory.

Return value

A list which will be populated with the details of the attachments that were retrieved.

This function may raise the following errors:

AttachError

  If there is some error querying the attachments

Example
Example of searching for and retrieving all attachments with the tag tag1

    >>> attachments = insight.get_attachs_by_tag('mytag1')
    ... for a in attachments:
    ...     print(a.filename)

Further information
1. The method get_attachs_by_tag is part of the class xpressinsight.AppInterface.
2. To maintain backwards compatibility, attachment operations will only raise exceptions on error if the raise_attach_exceptions attribute of either the AppConfig or AppInterface class is set to True. When this is not the case, after every call to this method you should check the value of insight.attach_status to see if your request succeeded.
3. Attempting to access attachments outside an Xpress Insight scenario will access local files that have been supplied to this class.
