Re: Rename a module with migration script

You can't do the operation from the migrations scripts of the module with the new name itself, as they are not going to be ever triggered.

  • Rename a module with migration script 
    Hello all!
We are trying to rename a module. The main purpose is to change the
name of the module itself, as well as xmlids, models and tables.

Preliminary step:
- Add a pre-migrate script like this one in new_name_module (bumping
the version number):
https://github.com/OCA/l10n-italy/pull/2220/commits/d6c790525e1892be1d04391054ccb779092c354c#diff-a86bc87cb07b27f04908e90baeb089a9182ad568d8e7205f40f3e689272bb76c

Test steps:

1) old_name module installation
2) add/change some data in Odoo
3) checkout to commit containing new_name module, migration script and
version bumped
4) launch old_name_module update:
./odoo-bin -c etc/odoo14.cfg -d testdb -u old_name_module --stop-after-init

Output:
old_name_module: not installable, skipped

In fact pre-migrate script is not triggered.


As an alternative to 4), we tried this:
4) launch new_name_module update:
./odoo-bin -c etc/odoo14.cfg -d testdb -u new_name_module --stop-after-init

But it didn't work as well.


The only way (we have found so far) to trigger pre-migrate script is this:

1) old_name module installation
2) add/change some data
3) checkout to commit containing new_name module, migration script and
version bumped
4) execute odoo shell
    >>> from openupgradelib import openupgrade
    >>> openupgrade.update_module_names(env.cr, [('old_name_module',
'new_name_module'),], merge_modules=False,)
    >>> env.cr.commit()
5) launch new_name_module update:
./odoo-bin -c etc/odoo14.cfg -d testdb -u new_name_module --stop-after-init


Do you know a way to trigger the migration script without using odoo shell?

Thanks in advance.
