Jessica Rynkar b74f4fb9b2 fix(ui): fallback to default locale checkbox passes wrong value (#12396)
### What?
Allows document to successfully be saved when `fallback to default
locale` checked without throwing an error.

### Why?
The `fallback to default locale` checkbox allows users to successfully
save a document in the admin panel while using fallback data for
required fields, this has been broken since the release of `v3`.

Without the checkbox override, the user would be prevented from saving
the document in the UI because the field is required and will throw an
error.

The logic of using fallback data is not affected by this checkbox - it
is purely to allow saving the document in the UI.

### How?
The `fallback` checkbox used to have an `onChange` function that
replaces the field value with null, allowing it to get processed through
the standard localization logic and get replaced by fallback data.
However, this `onChange` was removed at some point and the field was
passing the actual checkbox value `true`/`false` which then breaks the
form and prevent it from saving.

This fallback checkbox is only displayed when `fallback: true` is set in
the localization config.
This PR also updated the checkbox to only be displayed when `required:
true` - when it's the field is not `required` this checkbox serves no
purpose.

Also adds tests to `localization/e2e`.

Fixes #11245

  • Deploy anywhere, including serverless on Vercel for free
  • Combine your front+backend in the same /app folder if you want
  • Don't sign up for yet another SaaS - Payload is open source
  • Query your database in React Server Components
  • Both admin and backend are 100% extensible
  • No vendor lock-in
  • Never touch ancient WP code again
  • Build faster, never hit a roadblock

Quickstart

Before beginning to work with Payload, make sure you have all of the required software.

pnpx create-payload-app@latest

If you're new to Payload, you should start with the website template (pnpx create-payload-app@latest -t website). It shows how to do everything - including custom Rich Text blocks, on-demand revalidation, live preview, and more. It comes with a frontend built with Tailwind all in one /app folder.

One-click templates

Jumpstart your next project by starting with a pre-made template. These are production-ready, end-to-end solutions designed to get you to market as fast as possible.

🌐 Website

Build any kind of website, blog, or portfolio from small to enterprise. Comes with a fully functional front-end built with RSCs and Tailwind.

We're constantly adding more templates to our Templates Directory. If you maintain your own template, consider adding the payload-template topic to your GitHub repository for others to find.
