OctoberCMS Builder plugin with state and suburb - php

Question

I have created two plugins (States and Suburbs) using Builder plugin and so far it works great.
The Thing is, in States plugin, I am simply allowing ability to add state names and in Suburbs plugin, I am allowing users to select State first and then enter suburb name. All works fine as of now in these two plugins.
Now the thing is, I have a third plugin called as Properties in which I have both these 2 drop-downs State and Suburb but as of now All States and All Suburbs are showing. But I want users to select first State and then based on state selection it should should all its suburbs to my another Suburb drop-down.
I have tried to use dependsOn which Builder plugin provides but I just am not able to understand the flow to achieve it step by step based on the current scenario I have. Below is the code what I have done and tried so far.
plugins\technobrave\properties\models\Property.php
<?php namespace Technobrave\Properties\Models;
use Model;
use technobrave\states\Models\State as State;
use technobrave\suburbs\Models\Suburb as Suburb;
public function getStateIdOptions()
{
// getting all states
$get_all_states = State::all();
$fields[''] = 'Select any State';
foreach ($get_all_states as $current_state) {
$fields[$current_state->attributes['id']] = $current_state->attributes['state_name'];
}
ksort($fields);
return $fields;
}
public function getSuburbIdOptions($stateId)
{
// getting all suburbs
$get_all_suburbs = Suburb::all();
$fields[''] = 'Select any Suburb';
foreach ($get_all_suburbs as $current_suburb) {
$fields[$current_suburb->attributes['id']] = $current_suburb->attributes['suburb'];
}
ksort($fields);
return $fields;
}
}
How can I do this from here on ? Any help or guidance will be highly appreciated and useful.
Thanks

Ok Guys,
Eventually I have come up with a solution. Here is what I have done.
fields.yaml File: technobrave\properties\models\property\fields.yaml
state_id:
label: 'State:'
span: auto
required: 1
type: dropdown
tab: 'Address Information'
suburb_id:
label: 'Suburb:'
span: auto
required: 1
type: dropdown
tab: 'Address Information'
placeholder: 'Select any Suburb'
dependsOn: state_id
As you can see above,
In suburb_id I have added, below two lines of code.
placeholder: 'Select any Suburb'
dependsOn: state_id
Property Model File: technobrave\properties\models\Property.php
use Model;
use technobrave\states\Models\State as State;
use technobrave\suburbs\Models\Suburb as Suburb;
public function getStateIdOptions()
{
// getting all states
$get_all_states = State::all();
$fields[''] = 'Select any State';
foreach ($get_all_states as $current_state) {
$fields[$current_state->attributes['id']] = $current_state->attributes['state_name'];
}
ksort($fields);
return $fields;
}
public function getSuburbIdOptions()
{
return Suburb::getNameList($this->state_id);
}
Here above, I have just updated getSuburbIdOptions method with below code and removed my old code.
return Suburb::getNameList($this->state_id);
Then I went to my Suburbs plugin.
Suburb Model File: technobrave\suburbs\models\Suburb.php
And in this model file, I have made sure to use belongsTo and added getNameList method like below.
<?php namespace Technobrave\Suburbs\Models;
use Model;
use technobrave\states\Models\State as State;
/**
* Model
*/
class Suburb extends Model
{
/**
* #var string The database table used by the model.
*/
public $table = 'youtable_here_';
public $belongsTo = ['State' => [
'technobrave\states\Models\State',
'key' => 'state'
],
];
/**
* #var array Cache for nameList() method
*/
protected static $nameList = [];
public static function getNameList($stateId)
{
if (isset(self::$nameList[$stateId])) {
return self::$nameList[$stateId];
}
return self::$nameList[$stateId] = self::wherestate($stateId)->lists('suburb', 'id');
}
}
And it works.
Hope it will help to those who stuck on the same issue/implementation.
Thanks
