### What?
Fixes the issue when visiting the create view with the Join Field and
using postgres adapter
```
invalid input syntax for type integer: "NaN"
```
This happens because we don't have an ID yet and we send to the
database:
`WHERE id = NaN`
### How?
Avoids calling `getTableState` inside of `RelationshipTable` if there's
no ID yet, as it will always lead to the same empty result. While we
_could_ avoid error directly in the database adapter, I don't think we
should do that render request
Fixes https://github.com/payloadcms/payload/issues/9193
### What?
Fixes issue with incorrect `totalDocs` value when an aggregation is used
for `find`.
Previously, `limit: 5` for example always returned `totalDocs: 5`.
### Why?
`totalDocs` must be returned correctly.
### How?
Removes `$limit` from the pipeline, as `Model.aggregatePaginate` handles
it by itself.
### 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?
Makes it possible to filter join documents using a `where` added
directly in the config.
### Why?
It makes the join field more powerful for adding contextual meaning to
the documents being returned. For example, maybe you have a
`requiresAction` field that you set and you can have a join that
automatically filters the documents to those that need attention.
### How?
In the database adapter, we merge the requested `where` to the `where`
defined on the field.
On the frontend the results are filtered using the `filterOptions`
property in the component.

### What?
Since the join field, we do store relationship fields values in
`ObjectID`. This wasn't true if the field is nested to an array /
blocks.
### Why?
All relationship fields values should be stored in `ObjectID`.
### How?
Fixes arrays / blocks handling in the `traverseFields.ts` function.
Before it didn't run for them.
### What?
Properly specifies `$lookup.from` when the collection name is singular.
### Why?
MongoDB can pluralize the collection name and so can be different for
singular ones.
### How?
Uses the collection name from the driver directly
`adapter.collections[slug].collection.name` instead of just `slug`.
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

### What?
Fixes the issue with `in` querying when the collection has a join field.
### Why?
When using `.aggregate`, MongoDB doesn't cast a comma delimited value
for the `$in` operator to an array automatically as it's not handled by
Mongoose.
### How?
Sanitizes the incoming value to an array if it should.
Fixes https://github.com/payloadcms/payload/issues/8901
### What?
Allow specifying the defaultSort and defaultLimit to use for populating
a join field
### Why?
It is much easier to set defaults rather than be forced to always call
the join query using the query pattern ("?joins[categories][limit]=0").
### How?
See docs and type changes
Fixes https://github.com/payloadcms/payload/issues/8630
- Fixes `hasMany: true` and `localized: true` on the foreign field
- Adds `limit` to the subquery instead of hardcoded `11`.
- Adds the schema path `field.on` to the subquery, without this having 2
or more relationship fields to the same collection breaks joins
- Properly checks if the field is `hasMany`
There are two of the exact same e2e tests for the join field, which
throws an error when running these tests locally because they have
identical names.
## Description
- Adds a new "join" field type to Payload and is supported by all database adapters
- The UI uses a table view for the new field
- `db-mongodb` changes relationships to be stored as ObjectIDs instead of strings (for now querying works using both types internally to the DB so no data migration should be necessary unless you're querying directly, see breaking changes for details
- Adds a reusable traverseFields utility to Payload to make it easier to work with nested fields, used internally and for plugin maintainers
```ts
export const Categories: CollectionConfig = {
slug: 'categories',
fields: [
{
name: 'relatedPosts',
type: 'join',
collection: 'posts',
on: 'category',
}
]
}
```
BREAKING CHANGES:
All mongodb relationship and upload values will be stored as MongoDB ObjectIDs instead of strings going forward. If you have existing data and you are querying data directly, outside of Payload's APIs, you get different results. For example, a `contains` query will no longer works given a partial ID of a relationship since the ObjectID requires the whole identifier to work.
