[12 -> 13.0] muk_dms: OpenUpgrade: dms: error in migration script /opt/odoo/lib/addons/oca-mirror-dms/dms/migrations/13.0.8.1.0/post-migration.py: ('dms.file(3249,).content', None) #4881

[olaf-wagner]

When I run the migration in 13.0, it fails in the postmigration step for the dms. Im am using the latest versions of the openupgradelib (3.9.3) and the 13.0 branch from openupgrade itself.

Module

dms

Post-migration script fails with this error:

This may be a subsequent error, as I see some of these error logs before:

2025-03-24 16:20:03,383 2372 ERROR elego_v13 OpenUpgrade: Pass argument 'env_or_cr' as Cursor parameter until 16.0

I haven’t been able to isolate the problem further yet.
The actual data — dms.file(3249) — is there and should be correct (at least in the MuK tables); content is
one of the columns that are new or migrated.

To Reproduce

• not clear how to reproduce without the database in question yet

Expected behavior
Migration from muk_dms to dms should not fail.

Moved here from OCA/OpenUpgrade#4881 as requested by @victoralmau

[olaf-wagner]

Repeat comment by @victoralmau with explanation:

The problem is related to the dms code and/or the migration scripts included there.

I explain what happens:

Running https://github.com/OCA/dms/blob/13.0/dms/migrations/13.0.8.1.0/post-migration.py#L9 produces the error you indicate.
The error indicates that there is no value for the content field in file 3249.
The value of the content field in the files is defined with a compute according to different possibilities

dms/dms/models/dms_file.py

Line 395 in ca641ce

def _compute_content(self):

The reason why the error is displayed is because none of the 3 conditions are met, i.e. the file does not have content_file, content_binary or attachment_id defined. What is the reason why none of these values are defined in this (maybe other) file(s)?
The solution will be to define one of those values to all files. Another possibility would be to modify in dms 13.0 to make it possible to have the content field empty (this option would not be the most appropriate).

[olaf-wagner]

Here is the content of the original row in table muk_dms_file. AFAICS all values that are set in other entries are there:

id	locked_by	custom_thumbnail	custom_thumbnail_medium	custom_thumbnail_small	name	active	directory	storage	company	color	category	extension	mimetype	size	checksum	content_binary	create_uid	create_date	write_uid	write_date	reference_name	reference_model	reference_field	reference_id	content_file	automatic_thumbnail	automatic_thumbnail_medium	automatic_thumbnail_small	message_main_attachment_id	partner_id	invoice_number	date_invoice	user_id	import_type	invoice_type
3249					~$sign_Briefing_ASERVO_v01.docx	t	681	2	1	0		docx	application/vnd.openxmlformats-officedocument.wordprocessingml.document	162	1432a4d25b5a44945dfa11beaeff557fef09d2ad		7	2021-01-2317:44:28.646817	7	2021-01-2317:44:28.646817					/var/lib/odoo/files/elego_erp_v12/14/1432a4d25b5a44945dfa11beaeff557fef09d2ad
(1row)

The dms is working fine in v12 for that file, though it seems to be a bogus and unneeded entry.
If I remove 3249 from the table, we fail with another file:

odoo.exceptions.CacheMiss: ('dms.file(9835,).content', None)

This again has a strange name starting with ~$, so it may be related to certain characters in the filename.

A search shows only those two files with such strange name, so I delete them both for test purposes before the migration.

The next failure then is related to 000240.pdf with index 8615, so I assume these are just the first three files to be processed in that method.

id	locked_by	custom_thumbnail	custom_thumbnail_medium	custom_thumbnail_small	name	active	directory	storage	company	color	category	extension	mimetype	size	checksum	content_binary	create_uid	create_date	write_uid	write_date	reference_name	reference_model	reference_field	reference_id	content_file	automatic_thumbnail	automatic_thumbnail_medium	automatic_thumbnail_small	message_main_attachment_id	partner_id	invoice_number	date_invoice	user_id	import_type	invoice_type

(1row)

I've also checked that the content for the files is actually available in the volumes of the docker container:

wagner@odoo-mig-1:/opt/dconf/odoo-v13-ou$ docker-compose exec odoo /bin/bash -c 'ls -l /var/lib/odoo/files/elego_erp_v12/14/1432a4d25b5a44945dfa11beaeff557fef09d2ad'

wagner@odoo-mig-1:/opt/dconf/odoo-v13-ou$ docker-compose exec odoo /bin/bash -c 'ls -l /var/lib/odoo/files/elego_erp_v12/9f/9f127ea69ba96dd62530bd17160ffe579574ad0a'

It might be something simple I'm missing and overlooking all the time.

I'd still guess it is related to the errors previously reported from the openupgradelib:

2025-03-26 14:04:43,789 2598 ERROR elego_v13 OpenUpgrade: Pass argument 'env_or_cr' as Cursor parameter until 16.0

...

[victoralmau]

odoo.exceptions.CacheMiss: ('dms.file(9835,).content', None)

The problem is that the value of the content field is not set, maybe it is related to have access to the file indicated in content_file. @pedrobaeza do you have any idea what could be the reason?

[pedrobaeza]

I think the problem is because the DMS files are stored in a non compatible storage. MuK had other storages that are not supported by OCA.

[olaf-wagner]

It is correct that MuK DMS uses separate fielstores, though they have the same structure as the ones used by Odoo for the attachments. I have copied that filestore (below /var/lib/odoo/files) manually and mounted in the correct location into the docker image.
If the existing migration scripts do not support that, could it be a solution to just copy all the files into the regular Odoo filestore? I haven't tried that yet but it could work wrt. the structure used, I think.

[pedrobaeza]

I think that's the problem indeed.

[olaf-wagner]

I have tried

sudo rsync -au /var/lib/odoo/files/elego.erp_v12/elego_erp_v12/ /var/lib/odoo/filestore/odoo-v13/elego_v13/
sudo chown -R odoo:odoo /var/lib/odoo/filestore/odoo-v13/elego_v13/

now but the migration still aborts with the cache miss :-|
I'll check and try more later or tomorrow.
Perhaps we also need to adapt the paths stored in the content_file field. I'm not sure what the migration scripts actually except, but would have thought somebody has tried it before.

[pedrobaeza]

We did the migration from MuK DMS 12 to 13 with these scripts and worked, but it was a long time ago and don't remember the details of the used storage, sorry.

About the warning Pass argument 'env_or_cr' as Cursor parameter until 16.0, it's not the culprit of the problem.

[olaf-wagner]

Thank you, that's valuable information, Pedro. And it's really good to know that is has worked once before :-)
I think I'll figure out the storage problems.

[olaf-wagner]

I just want to post some updates here in case anybody else is interested. Things are progressing slowly.
I was able to continue with the overall migration by commenting out the recomputation of the mime type from the post migration steps. There were lots of other problems of course not related to DMS, but the overall structure got converted and is usable in version 14 with two exceptions:

• file content from the filestore is not heeded (we can reattach that later, if necessary, but will be looking into the code to do it properly)
• all users from the access groups are lost, because the corresponding relation table is not migrated

The latter can easily be fixed by

alter table muk_security_access_groups_users_rel rename to dms_access_group_users_rel

but we should probably also add a proper table renaming at the right position in the python code.
My colleague Mike is looking into the python issues but he's rather busy with other things.

I'll report here with some patches as soon as we have them.

[olaf-wagner]

I think this is the proper patch for the missing rename:
