Translation path from wagtailtrans to wagtail-localize

[ceelian]

Is there a migration path from wagtailtrans for existing installations to the new native translation system with wagtail-localize?

(As I am not aware to which project it may concern also added this in wagtail/wagtailtrans#208)

There's not really any overlap between Wagtail Localize and Wagtail trans since Wagtail Localize is a UI built on top of Wagtail's builtin translation models. Documentation for this is coming though!

I expect the move from Wagtail Trans to look like:

• Install Wagtail 2.11
• Replace wagtailtrans with a forked version that includes a data migration to port the data in TranslatablePage to Wagtail's builtin fields.
• Remove the translation root page (probably have to do this manually)

Thank you for the quick reply. I think I got the idea.

Install Wagtail 2.11

Hmm, that's not possible as wagtailtrans prevents the installation of wagtail 2.11. So I will try to fork wagtailtrans first and change that limitation to install it.

I finally managed to create a migration path. Because it finally needed some more steps as expected I wrote a blog post about it. I also created the necessary fork of wagtailtrans at https://github.com/carrotandcompany/wagtailtrans

If anyone has any suggestions, improvements, bugfixes to the migration path or the migration fork, I am happy to update the migration guide. Hope this is helpful for others as well.

@kaedroho thanks for the initial idea on how to execute the migration

@ceelian Hi, didn't you received an error like MainPage has no field named 'canonical_page' during your migration path?

[ceelian]

@mentecuantica I don't think so, at which step did the error occur?

@ceelian Hi, i'm following the steps on your blog post to migrate from wagtailtrans, but when i run the modified migration on step 4 i get the following error:

 line 11, in transfer_ids
    page.page_ptr = page.translatable_page_ptr
AttributeError: 'BasePage' object has no attribute 'translatable_page_ptr'
