# CRUD Create

ZingGrid has default behavior for **create** actions. There are expected inputs and outputs for a **create** action. You can, of course, extend or override this default behavior.

## CRUD Defaults

The default send and return values for CRUD actions are:

CRUD Defaults

| Action | Type | Response Codes: Success | Response Codes: Error | Returns |
| --- | --- | --- | --- | --- |
| Create row | POST | 200 - 299 | \>= 400 | **Expected Return Contents**
• Entire dataset
• Single record **or** ID of record |
| Read data | GET | 200 - 299 | \>= 400 | Expects a JSON or dataset response. |
| Update row | PUT | 200 - 299 | \>= 400 | Response is not read. |
| Update cell | PATCH | 200 - 299 | \>= 400 | Response is not read. |
| Delete row | DELETE | 200 - 299 | \>= 400 | Response is not read. |

## Override Defaults

If you need to override any default **create** actions, you can use `createOptions` to adjust all actions against the initial and subsequent fetches from the grid. [You can read more about available `createOptions` values here](https://www.zinggrid.com/docs/api-zg-param#zg-param-name-createOptions).

> **Note:** Remember, since `value` is an HTML attribute, it must be in valid JSON format and stringified.

Here is a list of available `createOptions`:

```javascript
{
  // to change the read method of the action to POST
  "method": "POST",
  // takes a JSON packet to be sent to the server in place of the action
  // in this case user_id is always one.
  "body": {user_id:1},
  "requestType": "application/json",
  "exclude": "",
  "headers": {"Authorization": "Basic super-secrete-key"},
  "mode": "no-cors",
  "responseType": "",
  "src": "",
  "queryString": ""
}
```

The body value can be a static JSON, like so:

```html
<!-- basic create option with static body -->
<zg-param name="createOptions" value='{"body": {"user_id":1}}'></zg-param>
```

The body value can also be a function which returns an object, like so:

```html
<!-- basic create option with function reference for body -->
<zg-param name="createOptions" value='{"body": "_fncStringReference"}'></zg-param>
```
```javascript
// function returns an object
function _fncStringReference(record) {
  return {
    // to change the read method of the action to POST
    method: 'POST',
    // takes a JSON packet to be sent to the server in place of the action
    // in this case user_id is always one.
    body: {user_id:1},
    requestType: 'application/json',
    exclude: '',
    headers: {"Authorization": "Basic super-secrete-key"},
    mode: 'no-cors',
    responseType: '',
    src: '',
    queryString: ''
  }
}
```
