djangocms_link/djangocms_picture to djangocms_frontend migration #184

Open aacimov opened 10 months ago

Is there a chance there will be a migration script for djangocms_link and djangocms_picture plugins which are, by my honest opinion, most used on lots of Django CMS based websites?

At the moment I am in a process of migrating the old Django CMS v3 with mentioned plugins (amongst others) and it would be a great option to migrate those to djangocms_frontend by ease. I must point out there is lots of data in the database I am migrating and only these 2 give me headache.

If not, are there any simple steps to transfer it easily (preferably with example)?

Thanks a lot!

Currently, there is no migration script for Link and/or picture plugins. However, it may not be difficult to create them: https://djangocms-frontend.readthedocs.io/en/latest/how-to/migrate-3rd-party-plugins.html The only difficulty I see, is that djangocms-link and djangocms-frontend use the same name for the link plugin. For the migration process the original link plugin might need to be renamed.

I'd suggest to look at:

Just be sure to make tests on a copied database first, where data loss would not matter.

Please let me know if I can assist with specific questions! This should be doable! 🚀

@fsbraun thanks!

I will definitely look into it. If I manage to do a migration process I will definitely share it.

Best regards.

Ok, I think I mapped the fields right but since bootstrap4_migration.pyis a subcommand it would be very helpful to point me in the right direction on how to do it as a standalone (single) command. Just a general bootstrapping of the command itself since there are lots of different methods in different files and it is giving me a hard time switching from different files "catching" the logic. I am afraid I could miss something.

I am working in a test environment of course, but still it would be very helpful.

Hi @aacimov !

If you have a mapping, put it into a file and in your settings.py set 

DJANGOCMS_FRONTEND_ADDITIONAL_MIGRATIONS = ["dotted.path.to.your.migration.mapping"]

Run manage frontend migrate and see if it works. If you do not want the djangocms-bootzstrap4 migrations to run, remove "djangocms_bootstrap4" from you INSTALLED_APPS and they will stay unaffected.
