🔗 Translating Ecto Changeset Errors in Phoenix

I recently received a great pull request for Keila, my Open Source email newsletter tool, that added a French translation. Even though I had previously translated Keila to German, it seems like I missed quite a few strings that should have been translated. One of the aspects I had previously neglected to translate were Ecto changeset errors from custom validations.

So in this how-to I’ll share what I learned when fixing this and how you can translate Ecto changeset errors in your own Phoenix applications.
