I have a problem with extracting data from the database.

My application is based on CodeIgniter 3 and AngularJS.

I have two tables in my database:

1. domains
2. organic search

In domains and organic_search, I have view_id columns - which are related to each other.

My problem: I connect to the database, when I go to a given domain URL, I get the domain ID (from the table domains), however, the data from the organic_search table is not collected. I have no idea how to connect the domains.iD relationship with domains.viewId = organic_search.viewId.

Below my code:

Controller domains.php

{
    $this->load->model('admin/analytics_model');
    $result = $this->analytics_model->get_by_domain_id($id);
    echo '{"records":' . json_encode( $result ) . '}';
}

Controller analytics.php

public function index($id = false)
{
    $result = $this->analytics_model->get($id);
    echo '{"records":' . json_encode( $result ) . '}';
}

Model analytics_model.php

public function get_by_domain_id($id)
{
    $this->db->where('id', $id);
    $q = $this->db->get('organic_search');
    $q = $q->result();
    return $q;
}
