I get the below error trying to update my database from 2.7.3 to 3.0.

Any ideas what to check?

(mayan-edms) ***@sjc1-mayan01:/usr/share/mayan-edms# mayan-edms.py
performupgrade

CommandError: Error during pre_upgrade signal: Migration

Hi,

I was able to track down the migration files causing this error but don't
seem to be able to correct the dependances in them.

/usr/share/mayan-edms/local/lib/python2.7/site-packages/mayan/apps/document_states/migrations/0005_auto_20170803_0638.py
-- contains ---
class Migration(migrations.Migration):

dependencies = [
('events', '0006_objecteventsubscription'),
('document_states', '0004_workflow_internal_name'),
]

and

/usr/share/mayan-edms/local/lib/python2.7/site-packages/mayan/apps/events/migrations/0006_objecteventsubscription.py

not sure how to get the event migration files to load first???

thanks!

Hi! Thanks for reporting this. I've started working on fixing this issue.
I'm removing all the squashed migrations, they were causing too many
problems. This feature of Django is not ready for production.

Are upgrading via the Docker image?

To migrate a specific app the command is:

mayan-edms.py migrate events

To migrate a specific migration of an app the command is:

mayan-edms.py migrate events 0004

I am using PIP to install/update, not the docker image.

There is still something wedged with 3.0.1 and get the same error in the
end using your suggestions...

thanks

Very good! That error means that the document with the UUID
a5985893-a3c5-47f0-8b8c-12bbb889b99f exists in the database but doesn't
exist in the disk. I can add code to skip this error but that would only
hide the problem and your installation's database and document storage will
still remain out of sync.

If you are using a dummy install of Mayan EDMS NG 3.0.2 to test the upgrade
make sure you copy the document_storage content too.

If this is a production installation, you can do a few things:

- Check a backup of your document_storage and find the file.
- Launch Mayan (metadata 0009 is the last migration), search the document
in question and delete it from the UI.
- Execute "touch
/usr/share/mayan-edms/local/lib/python2.7/site-packages/mayan/media/document_storage/a5985893-a3c5-47f0-8b8c-12bbb889b99f"
to create a blank file and allow the performupgrade command to finish.

Released version 3.0.1 which removes the squashed migrations. Give it a try.

Post by Michael Price
Are upgrading via the Docker image?
mayan-edms.py migrate events
mayan-edms.py migrate events 0004

Hi! Thanks for reporting this. I've started working on fixing this
issue. I'm removing all the squashed migrations, they were causing too many
problems. This feature of Django is not ready for production.

Hi,
I was able to track down the migration files causing this error but
don't seem to be able to correct the dependances in them.
/usr/share/mayan-edms/local/lib/python2.7/site-packages/mayan/apps/document_states/migrations/0005_auto_20170803_0638.py
-- contains ---
dependencies = [
('events', '0006_objecteventsubscription'),
('document_states', '0004_workflow_internal_name'),
]
and
/usr/share/mayan-edms/local/lib/python2.7/site-packages/mayan/apps/events/migrations/0006_objecteventsubscription.py
not sure how to get the event migration files to load first???
thanks!

I get the below error trying to update my database from 2.7.3 to 3.0.
Any ideas what to check?
mayan-edms.py performupgrade
No handlers could be found for logger "pyocr.libtesseract"
CommandError: Error during pre_upgrade signal: Migration
