Yii2: Rest POST Request Parameters not arriving

Good morning,

I dont get any further in this Topic so i am writing a Question here.

First of all i created a DB Table with Data from the Tutorial: https://www.yiiframework.com/doc/guide/2.0/en/start-databases

Then i created a Rest Controller from that Tutorial with the Data above: https://www.yiiframework.com/doc/guide/2.0/en/rest-quick-start

The first example GET Request from the Tutorial works fine and gives me all of the data from the DB. My Request URL: http://XX.X.X.12:XX90/country/

Now we come to my Error when trying to create a new Country in the DB via a POST Request. When using the CURL Command from underneath the Tutorial with my Test-Data i get following error:

SQLSTATE[HY000]: General error: 1364 Field 'code' doesn't have a default value**strong text**

(
    [0] => HY000
    [1] => 1364
    [2] => Field 'code' doesn't have a default value
)

My standard logging from rest api says that the POST Var is empty, but why? I also tested sending POST Request via a Tool (Postman) but i get the same error.

$_GET = []

$_POST = []

$_FILES = []

$_COOKIE = []

$_SERVER = [....]

My Model:

<?php

namespace appmodels;

use yiidbActiveRecord;

class Country extends ActiveRecord
{
}

My Controller:

<?php

namespace appcontrollers;

use yiirestActiveController;

class CountryController extends ActiveController
{
    public $modelClass = 'appmodelsCountry';
}

My CURL Request:

curl -i -H "Accept:application/json" -H "Content-Type:application/json" 
    -XPOST "http://XX.X.X.12:XX90/countries/" 
    -d '{"code": "TEST", "name": "TestCountry", "population": 01}'

return $config;

Suggestions?

Answer

You need to declare validation rules for working with the Rest API

Thanks to @Bizley

My Country Model now:

<?php

namespace appmodels;

use yiidbActiveRecord;

class Country extends ActiveRecord
{

    public function rules()
    {
        return [
            [['code', 'name', 'population'], 'required']
        ];
    }
}
