# use-inject-manager-on-public-methods - ESLint plugin rules

This rule requires that service methods accepting a `Context` parameter are decorated with `@InjectManager()` (public) or `@InjectTransactionManager()` (protected or private).

## Severity

`warn`. This rule is enabled in the [recommended](https://docs.medusajs.com/resources/lint#recommended) preset.

## What it Targets

This rule targets service files in your project's `src/modules` directory. It reports a method on a service class that accepts a `Context` parameter but isn't decorated with the appropriate manager decorator.

The following code is reported by the rule:

```ts title="src/modules/blog/service.ts"
import { MedusaService } from "@medusajs/framework/utils"

class BlogModuleService extends MedusaService({}) {
  async list(sharedContext: Context = {}) {}
}
```

Instead, decorate a public method with `@InjectManager()`:

```ts title="src/modules/blog/service.ts"
import {
  MedusaService,
  InjectManager,
} from "@medusajs/framework/utils"

class BlogModuleService extends MedusaService({}) {
  @InjectManager()
  async list(sharedContext: Context = {}) {}
}
```

## Why it's Important

The `@InjectManager()` and `@InjectTransactionManager()` decorators inject the entity manager into the method's context. Without them, the method runs without a managed transaction and database operations can fail.

Learn more in the [Database Operations in Services documentation](https://docs.medusajs.com/learn/fundamentals/modules/db-operations).

## Fixable

This rule is auto-fixable. Run the linter with the `--fix` option to apply the fix automatically.

## Turn it Off

To turn off this rule, set it to `off` in your ESLint configuration:

```ts title="eslint.config.ts"
import { defineConfig } from "eslint/config"
import medusa from "@medusajs/eslint-plugin"

export default defineConfig([
  ...medusa.configs.recommended,
  {
    rules: {
      "@medusajs/use-inject-manager-on-public-methods": "off",
    },
  },
])
```

Or disable it for a single line using an inline comment:

```ts
// eslint-disable-next-line @medusajs/use-inject-manager-on-public-methods
async list(sharedContext: Context = {}) {}
```
