### What?
Adds a new property to collection / global config `forceSelect` which
can be used to ensure that some fields are always selected, regardless
of the `select` query.
### Why?
This can be beneficial for hooks and access control, for example imagine
you need the value of `data.slug` in your hook.
With the following query it would be `undefined`:
`?select[title]=true`
Now, to solve this you can specify
```
forceSelect: {
slug: true
}
```
### How?
Every operation now merges the incoming `select` with
`collectionConfig.forceSelect`.
Previously, behavior with custom IDs and `select` query was incorrect.
By default, the `id` field is guaranteed to be selected, even if it
doesn't exist in the `select` query, this wasn't true for custom IDs.
Previously, if you selected only upload `hasMany: true` field, you would
receive an empty arrays always, because the `_rels` table wasn't joined
in this case. Fixes the condition to count `field.type === 'upload'` .
Fixes https://github.com/payloadcms/payload/issues/9606
With Postgres / SQLite, select fields (non `hasMany: true`) weren't
properly handled in the `traverseFields.ts` function for `select` query.
### What?
Adds full support for the point field to Postgres and Vercel Postgres
adapters through the Postgis extension. Fully the same API as with
MongoDB, including support for `near`, `within` and `intersects`
operators.
Additionally, exposes to adapter args:
*
`tablesFilter`https://orm.drizzle.team/docs/drizzle-kit-push#including-tables-schemas-and-extensions.
* `extensions` list of extensions to create, for example `['vector',
'pg_search']`, `postgis` is created automatically if there's any point
field
### Why?
It's essential to support that field type, especially if the postgres
adapter should be out of beta on 3.0 stable.
### How?
* Bumps `drizzle-orm` to `0.36.1` and `drizzle-kit` to `0.28.0` as we
need this change https://github.com/drizzle-team/drizzle-orm/pull/3141
* Uses its functions to achieve querying functionality, for example the
`near` operator works through `ST_DWithin` or `intersects` through
`ST_Intersects`.
* Removes MongoDB condition from all point field tests, but keeps for
SQLite

### What?
Generates types for `joins` property.
Example from our `joins` test, keys are type-safe:
<img width="708" alt="image"
src="https://github.com/user-attachments/assets/f1fbbb9d-7c39-49a2-8aa2-a4793ae4ad7e">
Output in `payload-types.ts`:
```ts
collectionsJoins: {
categories: {
relatedPosts: 'posts';
hasManyPosts: 'posts';
hasManyPostsLocalized: 'posts';
'group.relatedPosts': 'posts';
'group.camelCasePosts': 'posts';
filtered: 'posts';
singulars: 'singular';
};
};
```
Additionally, we include type information about on which collection the
join is, it will help when we have types generation for `where` and
`sort`.
### Why?
It provides a better DX as you don't need to memoize your keys.
### How?
Modifies `configToJSONSchema` to generate the json schema for
`collectionsJoins`, uses that type within `JoinQuery`
### What?
Adds `populate` property to Local API and REST API operations that can
be used to specify `select` for a specific collection when it's
populated
```ts
const result = await payload.findByID({
populate: {
// type safe if you have generated types
posts: {
text: true,
},
},
collection: 'pages',
depth: 1,
id: aboutPage.id,
})
result.relatedPost // only has text and id properties
```
```ts
fetch('https://localhost:3000/api/pages?populate[posts][text]=true') // highlight-line
.then((res) => res.json())
.then((data) => console.log(data))
```
It also overrides
[`defaultPopulate`](https://github.com/payloadcms/payload/pull/8934)
Ensures `defaultPopulate` doesn't affect GraphQL.
### How?
Implements the property for all operations that have the `depth`
argument.
### What?
Fixes type for the `select` property when having `strictNullChecks:
true` or `strict: true` in tsconfig.
### Why?
`select` should provide autocompletion for users, at this point it
doesn't work with this condtiion
### How?
Makes `collectionsSelect` and `globalsSelect` properties required in
`configToJSONSchema.ts`.
Fixes
https://github.com/payloadcms/payload/pull/8550#issuecomment-2452669237
### What?
Fixes `select` handling for properties inside of unnamed tabs using the
mongodb adapter.
Additionally, refactors `traverseFields` in drizzle to reuse logic from
groups / collapsible or rows if unnamed.
### Why?
`select` must work for any fields.
### How?
Fixes the `'tab'` case in `buildProjectionFromSelect` to handle when the
field is an unnamed tab.
Adds extra tests for named tabs / unnamed.
### What?
Adds `defaultPopulate` property to collection config that allows to
specify which fields to select when the collection is populated from
another document.
```ts
import type { CollectionConfig } from 'payload'
// The TSlug generic can be passed to have type safety for `defaultPopulate`.
// If avoided, the `defaultPopulate` type resolves to `SelectType`.
export const Pages: CollectionConfig<'pages'> = {
slug: 'pages',
// I need only slug, NOT the WHOLE CONTENT!
defaultPopulate: {
slug: true,
},
fields: [
{
name: 'slug',
type: 'text',
required: true,
},
],
}
```
### Why?
This is essential for example in case of links. You don't need the whole
document, which can contain large data but only the `slug`.
### How?
Implements `defaultPopulate` when populating relationships, including
inside of lexical / slate rich text fields.
Adds `select` which is used to specify the field projection for local
and rest API calls. This is available as an optimization to reduce the
payload's of requests and make the database queries more efficient.
Includes:
- [x] generate types for the `select` property
- [x] infer the return type by `select` with 2 modes - include (`field:
true`) and exclude (`field: false`)
- [x] lots of integration tests, including deep fields / localization
etc
- [x] implement the property in db adapters
- [x] implement the property in the local api for most operations
- [x] implement the property in the rest api
- [x] docs
