# Field Processor [#](https://gudhub.com/ru/docs/core-api/field-processor/#field-processor)

Field processor is responsible for receiving, updating fields models. Also with field processor you can get and update field values.

All field methods are collected and described in this article:

1.  [getField](#getfield)
    
2.  [updateField](#updatefield)
    
3.  [deleteField](#deletefield)
    
4.  [getFieldModels](#getfieldmodels)
    
5.  [getFieldValue](#getfieldvalue)
    
6.  [setFieldValue](#setfieldvalue)
    

## getField() [#](https://gudhub.com/ru/docs/core-api/field-processor/#getfield)

Due to this method you can get field from the relevant application. It takes application and field IDs as arguments.

Копировать

```js
async gudhub.getField(app_id, field_id)
```

| Argument Name | Type | Description |
| :-- | :-- | :-- |
| app\_id | `number` | _application ID where we want to get the field model_ |
| field\_id | `number` | _field ID that we want to receive_ |

Копировать

```js
import GudHub from '@gudhub/core';

const AUTHKEY = 'kLKKSlfjMmslk;eks;ldfspfk,v';
let app_id = 23;
let field_id = 34212;

(async ()=>{
    const gudhub = await new GudHub(AUTHKEY);
    let gottenField = await gudhub.getField(app_id, field_id);
    console.log(gottenField)
})();
```

Method returns field model from specific application:

```json
{
    "app_id": 23,
    "field_id": 34212,
    "data_type": "image",
    "name_space": "thumbnail",
    "field_priority": 0,
    "field_name": "Thumbnail",
    "data_model": {...}
}
```

```js
async gudhub.updateField(app_id, fieldModel);
```

| Argument Name | Type | Description |
| :-- | :-- | :-- |
| app\_id | `number` | _application ID where we want to update the field model_ |
| fieldModel | `object` | _contains existing field data_ |

Копировать

```js
import GudHub from '@gudhub/core';

const AUTHKEY = 'kLKKSlfjMmslk;eks;ldfspfk,v';
let app_id = 23;
let fieldModel = {
    "app_id": 23,
    "field_id": 505247,
    "data_type": "image",
    "name_space": "thumbnail",
    "field_priority": 0,
    "field_name": "Thumbnail",
    "data_model": {...}
};

(async ()=>{
    const gudhub = await new GudHub(AUTHKEY);
    let updatedField = await gudhub.updateField(app_id, fieldModel);
    console.log(updatedField)
})();
```

The method returns an updated field model:

Копировать

```json
{
    "app_id": 23,
    "field_id": 505247,
    "data_type": "image",
    "name_space": "thumbnail",
    "field_priority": 0,

Копировать

```js
gudhub.deleteField(app_id, field_id)
```

| Argument Name | Type | Description |
| :-- | :-- | :-- |
| app\_id | `number` | _application ID where we want to delete the field model_ |
| field\_id | `number` | _unique field ID_ |

let field_id = 34545;

(async ()=>{
    const gudhub = await new GudHub(AUTHKEY);
    let deletedField = await gudhub.deleteField(app_id, field_id);
    console.log(deletedField)
})();
```

In response, we will get the model of the deleted field.
