We used a custom\_language (created from a plugin) and now I moved the overrides to default ‘es’ but I see that users stills with the old option selected and I want to clean this.

How can I switch all the users language from Rails? I hope you can help me with this 🙂

Thanks!

Hey, thanks for your answer! I did it already but it seems that some users didn’t get their language fields updated.

Maybe there is some job to work on that or a manual way to update this specific workflow 🙂

Were you able to resolve your issue?

Do you recall if you had `Allow user locale` enabled, so your users can choose their own language interface via their preferences? I believe if that is disabled, everyone will be forced to use the default locale you specified in the `Default locale` setting.

It occurs to me that the `Default locale` setting should maybe work like the other User Preferences settings. When these settings are changed, you’re prompted with the option to apply the change historically for all users.

Oh, yes. I ended solving this issue exporting and importing the custom language _(ES\_XX)_ as default on _(ES on my case)_.

Thanks for your following up, I forget this thread.
