docs: updates to use DML and other changes (#7834)

- Change existing data model guides and add new ones for DML
- Change module's docs around service factory + remove guides that are now necessary
- Hide/remove all mentions of module relationships, or label them as coming soon.
- Change all data model creation snippets to use DML
- use `property` instead of `field` when referring to a data model's properties.
- Fix all snippets in commerce module guides to use new method suffix (no more main model methods)
- Rework recipes, removing/hiding a lot of sections as a lot of recipes are incomplete with the current state of DML.


### Other changes

- Highlight fixes in some guides
- Remove feature flags guide
- Fix code block styles when there are no line numbers.

### Upcoming changes in other PRs

- Re-generate commerce module references (for the updates in the method names)
- Ensure that the data model references are generated correctly for models using DML.
- (probably at a very later point) revisit recipes

In this chapter, you'll learn where to find resources on common data model definitions related to field's column types, relations, and indices.
## MikroORM Learning Resources
Refer to the following resources to learn about common definitions:
1. [Field column types](https://mikro-orm.io/docs/defining-entities).
2. [Creating indices](https://mikro-orm.io/docs/defining-entities#indexes).
Refer to MikroORM's documentation for more details related to your use case.
---
## Relations Between Data Models
You can build relations between data models in the same module using foreign keys.
Refer to [MikroORM's relations definitions](https://mikro-orm.io/docs/relationships) for more details.
<Note>
For building relationships between data models in different modules, refer to the [Module Relationships chapter](../../modules/module-relationships/page.mdx) instead.
</Note>
---
## Example Data Model
The following example showcase a data model with common definitions:
```ts collapsibleLines="1-10" expandButtonLabel="Show Imports"
import {
Entity,
Enum,
OneToOne,
PrimaryKey,
Property,
} from "@mikro-orm/core"
import { BaseEntity } from "@medusajs/utils"
// assuming this is another implemented data model
import ProductVariant from "./product-variant"
export enum MediaType {
MAIN = "main",
PREVIEW = "preview"
}
@Entity()
class ProductMedia extends BaseEntity {
@PrimaryKey({ columnType: "text" })
id: string
@Property({ columnType: "text" })
name: string
@Enum({ items: ["main", "preview"] })
type: MediaType
@Property({ columnType: "text" })
file_key: string
@Property({ columnType: "text" })
mime_type: string
@Property({ columnType: "text" })
variant_id: string
@OneToOne({
entity: ProductVariant,
onDelete: "cascade",
})
variant: ProductVariant
}
export default ProductMedia
```
In the example above:
- The `ProductMedia` data model has the columns `id`, `name`, `type`, `file_key`, `mime_type`, and `variant_id`.
- The data model has an index on the `variant_id` column.
- The data model has a one-to-one relation to a `ProductVariant` data model.

title: `${pageNumber} Configure Data Model Properties`,
}
# {metadata.title}
In this chapter, youll learn how to configure data model properties, such as setting their default value.
## Propertys Default Value
Use the `default` method of the `model` utility to specify the default value of a property.
For example:
export const defaultHighlights = [
["6", "default", "Set the default value to `black`."],
["9", "default", "Set the default value to `0`."]
]
```ts highlights={defaultHighlights}
import { model } from "@medusajs/utils"
const MyCustom = model.define("my_custom", {
color: model
.enum(["black", "white"])
.default("black"),
age: model
.number()
.default(0),
// ...
})
export default MyCustom
```
In this example, you set the default value of the `color` enum property to `black`, and that of the `age` number property to `0`.
---
## Nullable Property
Use the `nullable` method to indicate that a propertys value can be `null`.
For example:
export const nullableHighlights = [
["4", "nullable", "Configure the `price` property to allow `null` values."]
]
```ts highlights={nullableHighlights}
import { model } from "@medusajs/utils"
const MyCustom = model.define("my_custom", {
price: model.bigNumber().nullable(),
// ...
})
export default MyCustom
```
---
## Unique Property
The `unique` method indicates that a propertys value must be unique in the database.
For example:
export const uniqueHighlights = [
["5", "unique", "Configure the `email` property to allow unique values only."]
]
```ts highlights={uniqueHighlights}
import { model } from "@medusajs/utils"
const User = model.define("user", {
email: model.text().unique(),
// ...
})
export default User
```
In this example, multiple users cant have the same email.

export const metadata = {
title: `${pageNumber} Data Model Relationships`,
}
# {metadata.title}
In this chapter, youll learn how to define relationships between data models in your module.
## What is a Relationship Property?
A relationship property is defined using relation methods, such as `hasOne` or `belongsTo`. It represents a relationship between two data models in a module.
---
## One-to-One Relationship
To define a one-to-one relationship, create relationship properties in the data models using the following methods:
1. `hasOne`: indicates that the model has one record of the specified model.
2. `belongsTo`: indicates that the model belongs to one record of the specified model.
For example:
export const oneToOneHighlights = [
["5", "hasOne", "A user has one email."],
["10", "belongsTo", "An email belongs to a user."],
["11", `"email"`, "The relationship's name in the `User` data model."]
]
```ts highlights={oneToOneHighlights}
import { model } from "@medusajs/utils"
const User = model.define("user", {
id: model.id(),
email: model.hasOne(() => Email),
})
const Email = model.define("email", {
id: model.id(),
user: model.belongsTo(() => User, {
mappedBy: "email",
}),
})
```
The `hasOne` and `belongsTo` methods accept a function as a first parameter. The function returns the associated data model.
The `belongsTo` method also requires passing as a second parameter an object with the property `mappedBy`. Its value is the name of the relationship property in the other data model.
In the example above, a user has one email, and an email belongs to one user.
---
## One-to-Many Relationship
To define a one-to-many relationship, create relationship properties in the data models using the following methods:
1. `hasMany`: indicates that the model has more than one records of the specified model.
2. `belongsTo`: indicates that the model belongs to one record of the specified model.
For example:
export const oneToManyHighlights = [
["5", "hasMany", "A store has many products"],
["10", "belongsTo", "A product has one store."],
["11", `"products"`, "The relationship's name in the `Store` data model."]
]
```ts highlights={oneToManyHighlights}
import { model } from "@medusajs/utils"
const Store = model.define("store", {
id: model.id(),
products: model.hasMany(() => Product),
})
const Product = model.define("product", {
id: model.id(),
store: model.belongsTo(() => Store, {
mappedBy: "products",
}),
})
```
In this example, a store has many products, but a product belongs to one store.
---
## Many-to-Many Relationship
To define a many-to-many relationship, create relationship properties in the data models using the `manyToMany` method.
For example:
export const manyToManyHighlights = [
["5", "manyToMany", "An order is associated with many products."],
["10", "manyToMany", "A product is associated with many orders."]
]
```ts highlights={manyToManyHighlights}
import { model } from "@medusajs/utils"
const Order = model.define("order", {
id: model.id(),
products: model.manyToMany(() => Product),
})
const Product = model.define("product", {
id: model.id(),
order: model.manyToMany(() => Order),
})
```
In this example, an order is associated with many products, and a product is associated with many orders.
---
## Configure Relationship Property Name
The relationship property methods accept as a second parameter an object of options. The `mappedBy` property defines the name of the relationship in the other data model.
As seen in previous examples, the `mappedBy` option is required for the `belongsTo` method.
For example:
export const relationNameHighlights = [
["6", `"owner"`, "The relationship's name in the `Email` data model."],
["13", `"email"`, "The relationship's name in the `User` data model."]
]
```ts highlights={relationNameHighlights}
import { model } from "@medusajs/utils"
const User = model.define("user", {
id: model.id(),
email: model.hasOne(() => Email, {
mappedBy: "owner",
}),
})
const Email = model.define("email", {
id: model.id(),
owner: model.belongsTo(() => User, {
mappedBy: "email",
}),
})
```
In this example, you specify in the `User` data models relationship property that the name of the relationship in the `Email` data model is `owner`.
This is useful if the relationship propertys name is different than that of the associated data model.
---
## Cascades
When an operation is performed on a data model, such as record deletion, the relationship cascade specifies what related data model records should be affected by it.
For example, if a store is deleted, its products should also be deleted.
The `cascades` method used on a data model configures which child records an operation is cascaded to.
For example:
export const highlights = [
["8", "", "When a store is deleted, delete its associated products."]
]
```ts highlights={highlights}
import { model } from "@medusajs/utils"
const Store = model.define("store", {
id: model.id(),
products: model.hasMany(() => Product),
})
.cascades({
delete: ["products"],
})
const Product = model.define("product", {
id: model.id(),
store: model.belongsTo(() => Store, {
mappedBy: "products",
}),
})
```
The `cascades` method accepts an object. Its key is the operations name, such as `delete`. The value is an array of relationship property names that the operation is cascaded to.
In the example above, when a store is deleted, its associated products are also deleted.

## What is a Searchable Property?
Methods generated by the [service factory](../../modules/service-factory/page.mdx) that accept filters, such as `list{ModelName}s`, accept a `q` property as part of the filters.
When the `q` filter is passed, the query is applied on searchable properties in a data model.

## Define a Searchable Property
The `searchable` method of the `model` utility indicates that a `text` property is searchable.
For example:
```ts
import { model } from "@medusajs/utils"
const MyCustom = model.define("my_custom", {
name: model.text().searchable(),
// ...
})
export default MyCustom
```
In this example, the `name` property is searchable.
### Search Example
If you pass a `q` filter to the `listMyCustoms` method:
```ts
const myCustoms = await helloModuleService.listMyCustoms({
q: "John",
})
```
The `q` filter is applied on the `name` property of the `MyCustom` records.

## What is a Soft-Deletable Model?
## What is a Soft-Deletable Data Model?
A soft-deletable data model is a model whose records aren't actually removed from the database when they're deleted.
A soft-deletable data model is a model that has a `deleted_at` `dateTime` property.
Instead, their `deleted_at` field is set to the date the record was deleted.
When retrieving or listing records of that data model, records having their `deleted_at` field set aren't retrieved unless the `withDeleted` filter is provided.
When a record of the data model is deleted, this field is set to the current date, marking it as deleted.
---
## How to Create a Soft-Deletable Model?
## Configure Data Model Soft-Deletion
To create a soft-deletable model, first, add the following filter decorator to the data model class:
```ts title="src/module/hello/models/my-soft-deletable.ts" highlights={[["7"]]} collapsibleLines="1-7" expandButtonLabel="Show Imports"
// other imports...
import { Entity, Filter } from "@mikro-orm/core"
import { DALUtils } from "@medusajs/utils"
import { BaseEntity } from "@medusajs/utils"
@Entity()
@Filter(DALUtils.mikroOrmSoftDeletableFilterOptions)
class MySoftDeletable extends BaseEntity {
// ...
}
export default MySoftDeletable
```
Then, add a `deleted_at` field to the data model:
```ts highlights={[["7"], ["8"]]}
// other imports...
import { Property } from "@mikro-orm/core"
class MySoftDeletable extends BaseEntity {
// ...
@Property({ columnType: "timestamptz", nullable: true })
deleted_at: Date | null = null
}
```
---
## Manage Soft-Deletable Models
Services extending the service factory have methods to soft delete and restore records for all models specified during its creation.
### Soft Delete a Record
For example, to soft delete a `MySoftDeletable` record:
```ts
await helloModuleService.softDelete([
"id_123", "id_321",
])
```
The method receives an array of IDs of records to delete.
### Retrieve Soft-Deleted Records
The `retrieve`, `list`, and `listAndCount` methods accept as a second parameter a configuration object.
To retrieve soft-deleted records, set `withDeleted` to `true` in the configuration object passed as a second parameter.
For example:
```ts
const deletedRecords = await helloModuleService
.listMySoftDeletables({
// ...
}, {
withDeleted: true,
})
```
### Restore a Soft-Deleted Record
To restore a `MySoftDeletable` record:
```ts
await helloModuleService.restore([
"id_123", "id_321",
])
```
The method also receives an array of IDs of records to restore.
If the data model isn't the main data model, its method names are `softDelete` and `restore` suffixed with the plural name of the model. For example, `softDeleteMySoftDeletable`.
By default, all data models have a `deleted_at` property and are considered soft-deletable.
