# Binding to Model

## Set up Binding to the input & output model

After creating the input and output model, it is necessary to set this model to the conditions and results in the decision table designer.

* Input model is bound to conditions.
* Output model is bound to results.

{% hint style="info" %}
Any leaf from the **input/output** model can be selected to set the **condition/result** variable. You cannot select a root that contains only one child as a **condition/result** variable.
{% endhint %}

#### Example of binding (Input Model):

```javascript
{
  "delivery": {
    "distance": {
      "car": {},
      "ship": {},
      "plane": {}
    },
    "tariff": {}
  },
  "package": {
    "weight": {},
    "longestSide": {}
  }
}
```

When this Input Model is modeled, the following values can be selected as the condition value:

* delivery.distance.car
* delivery.distance.ship
* delivery.distance.plane
* delivery.tariff
* package.weight
* package.longestSide

### Binding Input model to Conditions

1. Go to **decision table detail**.
2. Go to section **Decision Table Designer**.
3. Create a new **condition**.
4. Select the **condition variable**.

{% hint style="info" %}
More information is in [Table Designer](/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/decision-table-designer.md#select-value-from-input-model).
{% endhint %}

### Binding Output model to Result

1. Go to **decision table detail**.
2. Go to section **Decision Table Designer**.
3. Create a new **result**.
4. Select the **result variable**.

{% hint style="info" %}
More information is in [Table Designer](/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/decision-table-designer.md#select-value-from-output-model).
{% endhint %}

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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.decisionrules.io/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/binding-to-model.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
