# xpressinsight.AppInterface.list_app_attach_by_tag

Purpose
Retrieves a list of all the files attached to the app with the given tag.
Synopsis
`xpressinsight.AppInterface.list_app_attach_by_tag(self, tag: str) -> List[Attachment]`
Argument

tag | The tag to search for

Return value

A list of the app attachments.

This function may raise the following errors:

AttachError

  If there is some error listing the attachments.

Example
Example of fetching information about all attachments on the app with the tag tag1 into a list called atts

    >>> atts = insight_list_app_attach_by_tag('mytag1')
    ... print("Attachments: ", atts)

Further information
1. The method list_app_attach_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.
