# Model Object Namespace

The default namespace is not specifying one. This namespace is used to retreive either named mappings or full component paths.

| DSL                   | Description                                                                                                          |
| --------------------- | -------------------------------------------------------------------------------------------------------------------- |
| empty                 | Same as saying *id*. Get a mapped instance with the same name as defined in the property, argument or setter method. |
| id                    | Get a mapped instance with the same name as defined in the property, argument or setter method.                      |
| id:{name}             | Get a mapped instance by using the second part of the DSL as the mapping name.                                       |
| id:{name}:{method}    | Get the {name} instance object, call the {method} and inject the results                                             |
| model                 | Get a mapped instance with the same name as defined in the property, argument or setter method.                      |
| model:{name}          | Get a mapped instance by using the second part of the DSL as the mapping name.                                       |
| model:{name}:{method} | Get the {name} instance object, call the {method} and inject the results                                             |

```javascript
// Let's assume we have mapped a few objects called: UserService, SecurityService and RoleService

// Empty inject, use the property name, argument name or setter name
property name="userService" inject;

// Using the name of the mapping as the value of the inject
property name="security" inject="SecurityService";

// Using the full namespace
property name="userService" inject="id:UserService";
property name="userService" inject="model:UserService";

// Simple factory method
property name="roles" inject="id:RoleService:getRoles";
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://coldbox.ortusbooks.com/v4.x-1/the-basics/models/injection-dsl/model-object-namespace.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
