Remove transformations from 1800 documents

[RBS]

Just recently started using Mayan and we had a user upload around 1800 documents.  Almost all of these documents had a transformation of {"degrees": 180} added and should not have.  How can I easily remove the transformations from all documents in the system?  Thanks!

BTW, We are using version 2.7.3 running under docker

This was most likely caused by the automatic orientation detection. This feature now defaults to disable since PDF are not always compliant. In 3.0 it is possible to select all the document in a page (40) and delete the transformations. A entry can be added to the "Tools" menu to clear all transformation in the system. In the meantime the only solution would be to launch a Python shell inside the Docker instance using:

docker exec -ti <docker container name> /bin/bash

The launcher a Python shell connected to Mayan.

/usr/local/python shell

execute the following:

from documents.models import Document

from converter.models import Transformation

[Transformation.objects.get_for_model(document).delete() for document in Document.objects.all()]

I'll push the option of adding an entry to the tools menu to clear all transformation in the queue for next version.
