I have a table called items
and a table called item_pics
.
item_pics
has an item_id
, file_name
and a rank
field (among others).
What I'm looking for is for each item
my index
page's $items
array to contain the file_name
from the item_pics
matching the item
's item_id
with the lowest rank
. So I can access like (or something like) this in my Items/index.ctp
:
foreach ($items as $item):
$img = $item['Item']['ItemPic']['file_name'];
...
I'm pretty new to CakePHP, this is my first project. I thought that this within the Item
model would cause item_pics
data to be pulled (although I figured all related item_pics
for each item
would get pulled rather than just the one with the lowest rank
):
public $hasMany = array(
'ItemPic' => array(
'className' => 'ItemPic',
'foreignKey' => 'item_id',
'dependent' => false
)
}
but I can see that no item_pics
data is loaded (at the bottom of items/index
):
SELECT `Item`.`id`, `Item`.`title`, `Item`.`description`, `Item`.`created`, `Item`.`modified`, `Item`.`type`, `Project`.`id`, `Project`.`item_id`, `Project`.`title`, `Project`.`description`, `Project`.`rank`, `Project`.`created`, `Project`.`modified`
FROM `laurensabc`.`items` AS `Item`
LEFT JOIN `laurensabc`.`projects`
AS `Project`
ON (`Project`.`item_id` = `Item`.`id`)
WHERE `Item`.`type` IN (1, 2)
LIMIT 20
also, while I would like projects
to be joined in the view
pages, I don't really need them in the index
page.
I've done some searching and haven't been able to find exactly what I'm looking for. I suppose I could do a query within the index
view item loop, but I'm trying to make sure I do things the right way... the CakePHP way. I assume I need to change something about my model relationships but I haven't had any luck.
CakePHP - Associations - HasMany, this makes it seem like I could order by rank and limit 1. But this didn't work... and even if it did, I wouldn't want that to affect the view
pages but rather just the index
page.
My Controller looks like this:
public function index($type = null) {
$this->Item->recursive = 0;
$conditions = array();
if ($type == "sale") {
$conditions = array(
"Item.type" => array(self::FOR_SALE, self::FOR_SALE_OR_RENT)
);
} else if ($type == "rent" ) {
$conditions = array(
"Item.type" => array(self::FOR_RENT, self::FOR_SALE_OR_RENT)
);
} else {
$conditions = array("Item.type !=" => self::HIDDEN);
}
$paginated = $this->Paginator->paginate($conditions);
debug($paginated);
$this->set('items', $paginated);
$this->set('title', ($type == null ? "Items for Sale or Rent" : "Items for " . ucwords($type)));
}
I have also tried this on my controller, but it doesn't seem to do anything either:
$this->paginate = array(
'conditions' => $conditions,
'joins' => array(
array(
'alias' => 'ItemPic',
'table' => 'item_pics',
'type' => 'left',
'conditions' => array('ItemPic.item_id' => 'Item.id'),
'order' => array('ItemPic.rank' => 'asc'),
'limit' => 1
)
)
);
$paginated = $this->paginate($this->Item);
