Previously, this worked with MongoDB but failed with Postgres / SQLite
when the `slug` field has both `localized: true` and `unique: true`.
```ts
await payload.create({
collection: "posts",
locale: "en",
data: {
slug: "my-post"
}
})
await payload.create({
collection: "posts",
locale: "de",
data: {
slug: "my-post"
}
})
```
Now, we build unique constraints and indexes in combination with the
_locale column. This should also improve query performance for fields
with both index: true and localized: true.
### Migration steps (Postgres/SQLite only)
This change updates the database schema and requires a migration (if you
have any localized fields). To apply it, run the following commands:
```sh
pnpm payload migration:create locale_unique_indexes
pnpm payload migrate
```
Note that if you use `db.push: true` which is a default, you don't have
to run `pnpm payload migrate` in the development mode, only in the
production, as Payload automatically pushes the schema to your DB with
it.
Payload SQLite Adapter
Official SQLite adapter for Payload.
Installation
npm install @payloadcms/db-sqlite
Usage
import { buildConfig } from 'payload/config'
import { sqliteAdapter } from '@payloadcms/db-sqlite'
export default buildConfig({
db: sqliteAdapter({
client: {
url: process.env.DATABASE_URI,
},
}),
// ...rest of config
})
More detailed usage can be found in the Payload Docs.
