Octobercms child relationship of relationships - php

Question

Im working in a octobercms plugin and i have the following models in it:
Houses
Pays
Owners
In Houses model i have the following relationship:
public $hasManyThrough = [
'owner' => [
'Author\Plugin\Models\Owner',
'table' => 'author_plugin_houses_owners',
'key' => 'houses_id',
'otherKey' => 'owners_id'
]
];
this relationship has a intermediate table 'author_plugin_houses_owners':
+------------+-------------+--------+
| hoses_id | owners_id | active |
+------------+-------------+--------+
And in Pays model i have the following relationship:
public $belongsTo = [
'houses' => ['Author\Plugin\Models\Houses']
];
this model corresponds to a table like this:
+----+----------+---------+-------+------+
| id | hoses_id | amounth | payed | debt |
+----+----------+---------+-------+------+
in the table i have a column "houses_id", the question is, how i can access to "owner" relationship declared in "Houses" model since "Pays" model? i need access to it because i need printed "owner_name" on list view in the plugin backend.
owner table:
+----+------------+--------+
| id | owner_name | active |
+----+------------+--------+
thanks a lot!

Answer 1

I assume that Pay belongs to only one house.
public $belongsTo = [
'house' => ['Author\Plugin\Models\Houses']
// ^ you can use house instead houses for relation name
];
Now we can access owner with relation chain
$payModel->house->owner
Since you made relation hasMany one house can have multiple owners [ hasManyThrough ]
so this will return you a list of owners.
As in list view you need to use it, You can define partial type column
columns:
id:
label: id
type: number
searchable: true
sortable: true
.... other fields ...
owner_name:
label: Owner
type: partial
path: $/hardiksatasiya/demotest/models/sort/_ownername_column.htm
Make sure to replace the path with your own plugin author name and path.
Now inside partial, you can write your actual logic [ this must be in PHP not in twig ]
<?php
// this is hasmany relation so we expect multiple owners
$owners = $record->house->owner;
$ownerArr = [];
foreach($owners as $ownr) {
$ownerArr[] = $ownr->owner_name;
}
$output = implode($ownerArr, ', ');
?>
<?php echo $output ?>
If there is only one owner it will show Hardik one name only if there are multiple owners it will show Hardik, Noe comma separated values.
if any doubts please comment.
