i have a ParentItem model
$parentItem = ParentItem::get()->first();
I have this array
$items = array(
array(
'title' => 'test1',
'desc' => 'test1'
),
array(
'title' => 'test2',
'desc' => 'test2'
)
);
i want to add it as a has many relationship.
so i can do:
foreach($items as $item) {
$parentItem->items()->create($item)
}
is there any way way to create all at once..?
something like:
$parentItem->items()->createMany($items);
You can tryout two path.
Using saveMany method:
$parentItem = ParentItem::first();
$items = array(
new Item(['title' => 'test1','desc' => 'test1']),
new Item(['title' => 'test2','desc' => 'test2'])
);
$parentItem->items()->saveMany($items)
For further info you can read here.
https://laravel.com/docs/5.1/eloquent-relationships#inserting-related-models
Using insert method:
$parentItem = ParentItem::first();
$items = array(
array('title' => 'test1','desc' => 'test1','parent_item_id' => $parentItem->id),
array('title' => 'test2','desc' => 'test2','parent_item_id' => $parentItem->id)
);
Item::insert($items);
Remember in insert created_at and updated_at won't be inserted automatically, you have to provide them in the array if you have them in your table. For further info you can read here.
https://laravel.com/docs/5.1/queries#inserts
As of right now, you may use the createMany Eloquent method to achieve this.

I am trying to take advantage of CakePHP's saveMany feature (with associated data feature), however am creating duplicate records. I think it is because the find() query is not finding authors, as the transaction has not yet been committed to the database.
This means that if there are two authors with the same username, for example, in the spreadsheet, then CakePHP will not associate the second with the first, but rather create two. I have made up some code for this post:
/*
* Foobar user (not in database) entered twice, whereas Existing user
* (in database) is associated
*/
$spreadsheet_rows = array(
array(
'title' => 'New post',
'author_username' => 'foobar',
'content' => 'New post'
),
array(
'title' => 'Another new post',
'author_username' => 'foobar',
'content' => 'Another new post'
),
array(
'title' => 'Third post',
'author_username' => 'Existing user',
'content' => 'Third post'
),
array(
'title' => 'Fourth post', // author_id in this case would be NULL
'content' => 'Third post'
),
);
$posts = array();
foreach ($spreadsheet_rows as $row) {
/*
* This query doesn't pick up the authors
* entered automatically (see comment 2.)
* within the db transaction by CakePHP,
* so creates duplicate author names
*/
$author = $this->Author->find('first', array('conditions' => array('Author.username' => $row['author_username'])));
$post = array(
'title' => $row['title'],
'content' => $row['content'],
);
/*
* Associate post to existing author
*/
if (!empty($author)) {
$post['author_id'] = $author['Author']['id'];
} else {
/*
* 2. CakePHP creates and automatically
* associates new author record if author_username is not blank
* (author_id is NULL in db if blank)
*/
if (!empty($ow['author_username'])) {
$post['Author']['username'] = $row['author_username'];
}
}
$posts[] = $post;
}
$this->Post->saveMany($posts, array('deep' => true));
Is there any way that this can be achieved, while also keeping transactions?
Update
You new requirement to save also posts that have no associated authors changes the situation a lot, as mentioned in the comments, CakePHPs model save methods are not ment to be able to save data from different models at once if it's not an association, if you need to do this in a transaction, then you'll need to handle this manually.
Save authors and their posts instead of posts and their authors
I would suggest that you save the data the other way around, that is save authors and their associated posts, that way you can easily take care of the duplicate users by simply grouping their data by using the username.
That way around CakePHP will create new authors only when neccessary, and add the appropriate foreign keys to the posts automatically.
The data should then be formatted like this:
Array
(
[0] => Array
(
[username] => foobar
[Post] => Array
(
[0] => Array
(
[title] => New post
)
[1] => Array
(
[title] => Another new post
)
)
)
[1] => Array
(
[id] => 1
[Post] => Array
(
[0] => Array
(
[title] => Third post
)
)
)
)
And you would save via the Author model:
$this->Author->saveMany($data, array('deep' => true));
Store non associated posts separately and make use of transactions manually
There is no way around this if you want to use the CakePHP ORM, just imagine what the raw SQL query would need to look like if it would need to handle all that logic.
So just split this into two saves, and use DboSource::begin()/commit()/rollback() manually to wrap it all up.
An example
Here's a simple example based on your data, updated for your new requirements:
$spreadsheet_rows = array(
array(
'title' => 'New post',
'author_username' => 'foobar',
'content' => 'New post'
),
array(
'title' => 'Another new post',
'author_username' => 'foobar',
'content' => 'Another new post'
),
array(
'title' => 'Third post',
'author_username' => 'Existing user',
'content' => 'Third post'
),
array(
'title' => 'Fourth post',
'content' => 'Fourth post'
),
array(
'title' => 'Fifth post',
'content' => 'Fifth post'
),
);
$authors = array();
$posts = array();
foreach ($spreadsheet_rows as $row) {
// store non-author associated posts separately
if (!isset($row['author_username'])) {
$posts[] = $row;
} else {
$username = $row['author_username'];
// prepare an author only once per username
if (!isset($authors[$username])) {
$author = $this->Author->find('first', array(
'conditions' => array(
'Author.username' => $row['author_username']
)
));
// if the author already exists use its id, otherwise
// use the username so that a new author is being created
if (!empty($author)) {
$authors[$username] = array(
'id' => $author['Author']['id']
);
} else {
$authors[$username] = array(
'username' => $username
);
}
$authors[$username]['Post'] = array();
}
// group posts under their respective authors
$authors[$username]['Post'][] = array(
'title' => $row['title'],
'content' => $row['content'],
);
}
}
// convert the string (username) indices into numeric ones
$authors = Hash::extract($authors, '{s}');
// manually wrap both saves in a transaction.
//
// might require additional table locking as
// CakePHP issues SELECT queries in between.
//
// also this example requires both tables to use
// the default connection
$ds = ConnectionManager::getDataSource('default');
$ds->begin();
try {
$result =
$this->Author->saveMany($authors, array('deep' => true)) &&
$this->Post->saveMany($posts);
if ($result && $ds->commit() !== false) {
// success, yay
} else {
// failure, buhu
$ds->rollback();
}
} catch(Exception $e) {
// failed hard, ouch
$ds->rollback();
throw $e;
}
You need to use saveAll, which is a mix between saveMany and saveAssociated (you will need to do both of them here).
Plus, you need to change the structure of each post.
Here is an example of the structures you will need to create inside the loop.
<?php
$posts = array();
//This is a post for a row with a new author
$post = array (
'Post' => array ('title' => 'My Title', 'content' => 'This is the content'),
'Author' => array ('username' => 'new_author')
);
$posts[] = $post;
//This is a post for a row with an existing author
$post = array (
'Post' => array ('title' => 'My Second Title', 'content' => 'This is another content'),
'Author' => array ('id' => 1)
);
$posts[] = $post;
//This is a post for a row with no author
$post = array (
'Post' => array ('title' => 'My Third Title', 'content' => 'This is one more content')
);
$posts[] = $post;
$this->Post->saveAll($posts, array ('deep' => true));
?>
Following the "use transactions manually" bit suggested by ndm, this piece of code (written in a unit test!) seemed to do the trick:
public function testAdd() {
$this->generate('Articles', array());
$this->controller->loadModel('Article');
$this->controller->loadModel('Author');
$csv_data = array(
array(
'Article' => array(
'title' => 'title'
)),
array(
'Article' => array(
'title' => 'title'
),
'Author' => array(
'name' => 'foobar'
),
),
array(
'Article' => array(
'title' => 'title2'
),
'Author' => array(
'name' => 'foobar'
)
),
/* array( */
/* 'Article' => array( */
/* 'title' => '' */
/* ), */
/* 'Author' => array( */
/* 'name' => '' // this breaks our validation */
/* ) */
/* ), */
);
$db = $this->controller->Article->getDataSource();
$db->begin();
/*
* We want to inform the user of _all_ validation messages, not one at a time
*/
$validation_errors = array();
/*
* Do this by row count, so that user can look through their CSV file
*/
$row_count = 1;
foreach ($csv_data as &$row) {
/*
* If author already exists, don't create new record, but associate to existing
*/
if (!empty($row['Author'])) {
$author = $this->controller->Author->find('first',
array(
'conditions' => array(
'name' => $row['Author']['name']
)
));
if (!empty($author)) {
$row['Author']['id'] = $author['Author']['id'];
}
}
$this->controller->Article->saveAssociated($row, array('validate' => true));
if (!empty($this->controller->Article->validationErrors)) {
$validation_errors[$row_count] = $this->controller->Article->validationErrors;
}
$row_count++;
}
if (empty($validation_errors)) {
$db->commit();
} else {
$db->rollback();
debug($validation_errors);
}
debug($this->controller->Article->find('all'));
}
I have problem, becouse only last item from loop is saved in database.
Im using CakePhp 2.x
Controller:
for ($x=1; $x <= count($this->request->data['Goodsandoffer'])/3;$x++){
$promID = $this->request->data['Goodsandoffer']['promotionaloffer_id_'.$x];
if($this->request->data['Goodsandoffer']['cenaPromocyjna_'.$x] != ''){
$helperReqestTable3 = array('promotionaloffer_id'=>$this->request->data['Goodsandoffer']['promotionaloffer_id_'.$x],'good_id'=>$this->request->data['Goodsandoffer']['good_id_'.$x],'cenaPromocyjna'=>$this->request->data['Goodsandoffer']['cenaPromocyjna_'.$x]);
$helperReqestTable['Goodsandoffer']=$helperReqestTable3;
debug($helperReqestTable);
$this->Goodsandoffer->save($helperReqestTable);
}
}
Here is how look my debug in loop:
array(
'Goodsandoffer' => array(
'promotionaloffer_id' => '7',
'good_id' => '18',
'cenaPromocyjna' => '1'
)
)
And in next interation:
array(
'Goodsandoffer' => array(
'promotionaloffer_id' => '7',
'good_id' => '19',
'cenaPromocyjna' => '2'
)
)
In database is created only one row with last item.
Model:
class Goodsandoffer extends AppModel {
public $displayField = 'id';
public $belongsTo = array(
'Promotionaloffer' => array(
'className' => 'Promotionaloffer',
'foreignKey' => 'promotionaloffer_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
'Good' => array(
'className' => 'Good',
'foreignKey' => 'good_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
}
Have you tried calling $this->Goodsandoffer->create() before you call save? That way you're definitely telling Cake to create a new record each time.
The general process of creating and saving data in Cake is:
$this->Model->create()
$this->Model->set($data_array)
$this->Model->save()
You can also eliminate step 2 above by passing you $data_array to the save() function:
$this->Model->create();
$this->Model->save($data_array);
NOTE: from the manual (if you aren't using create()):
When calling save in a loop, don’t forget to call clear().
Another way you could create new data would be to make sure the primary key for your model is null in the data set you pass into save, although this is a little less obvious and probably best to stick to the create/[set/]save flow:
$data = array('id' => null, 'somefield' => 'foobar');
$this->Model->save($data); // new record created
In cakephp 2.0 $this->Model->create() create work fine. But if you are using cakephp version 3 or greater then 3. Then follow the below code
$saveData['itemId'] = 1;
$saveData['qty'] = 2;
$saveData['type'] = '0';
$saveData['status'] = 'active';
$saveData = $this->Model->newEntity($saveData);
$this->Model->save($materialmismatch);
In normal case we use patchEntity
$this->Model->patchEntity($saveData, $this->request->data);
It will only save last values of array so you have to use newEntity() with data
I want to make an if else in filterArgs (in Model) as follow:
public $filterArgs = array(
array('name' => 'to', 'type' => 'value' => 'Product.regular_price' ),
);
I want the field to change base on the condition.
if sale = 1, field is promo_price, else field is regular_price
I already try below code (but unsuccessful):
'field'=> 'Product.sale' => 1 ? 'Product.promo_price >=' : 'Product.regular_price >='
Can someone please help me. Thanks alot in advance!
I would create a virtualField in my Product Model
$virtualFields = array
(
'my_price' => 'IF(Product.sale = 1, Product.promo_price, Product.regular_price)';
)
public $filterArgs = array
(
'my_price' => array('type' => 'value'),
);
I have a CakePHP controller like this:
$this->loadModel('Project');
$list2 = $this->Project->find( 'list', array(
'fields' => array('Project.project'),
'conditions' => array('Project.user_id' => $userId)
));
$this->set($list2, 'list2');
$this->loadModel('Distance');
if(!empty($this->request->data)){
$this->Distance->create();
if ($this->Distance->save($this->request->data)) {
$this->Session->setFlash('Saved.');
// $this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash('FAILED');
}
}else{
// $this->Session->setFlash('test');
}
and a view like this:
echo $this->Form->input('Distance.project', array('options' => $list2, 'label' => false, 'empty' => '(choose one)' ;
But I get inserted to the database the id of the project instead of the project name.
I never have such problems working with the fields - just with a list of data.
Any idea why it happens?
It's normal ... The $list2 it's and array ... and the values of the options are the indexes from that array.
If you want to insert only the project name you need to change $list2 with $list2['project_name']. You need to remove or replace the indexes of $list2.
LE: take iexiak example. He change also the code for you.
$list2 = $this->Project->find( 'list', array(
'fields' => array('Project.project'),
'conditions' => array('Project.user_id' => $userId)
)
);
This is because $list2 automatically creates a list of ID => project; and when you use that as input for your form it automatically creates the drop down to reflect this. This is generally the best practice, to link to ID's instead of to descriptions, as ID's do not change as often. The below should get you exactly what you want though:
$list2 = $this->Project->find( 'list', array(
'fields' => array('Project.project','Project.project'),
'conditions' => array('Project.user_id' => $userId)
)
);
It feels like I've tried everything so I now come to you.
I am trying to order my data but it isn't going so well, kinda new to Cake.
This is my code:
$this->set('threads', $this->paginate('Thread', array(
'Thread.hidden' => 0,
'Thread.forum_category_id' => $id,
'order' => array(
'Thread.created' => 'desc'
)
)));
It generates an SQL error and this is the last and interesting part:
AND `Thread`.`forum_category_id` = 12 AND order = ('desc') ORDER BY `Thread`.`created` ASC LIMIT 25
How can I fix this? The field created obviously exists in the database. :/
You need to pass in the conditions key when using multiple filters (i.e. order, limit...). If you just specify conditions, you can pass it as second parameter directly.
This should do it:
$this->set('threads', $this->paginate('Thread', array(
'conditions' => array(
'Thread.hidden' => 0,
'Thread.forum_category_id' => $id
),
'order' => array(
'Thread.created' => 'desc'
)
)));
or perhaps a little clearer:
$this->paginate['order'] = array('Thread.created' => 'desc');
$this->paginate['conditions'] = array('Thread.hidden' => 0, ...);
$this->paginate['limit'] = 10;
$this->set('threads', $this->paginate());
if you get an error, add public $paginate; to the top of your controller.
Try
$this->set('threads', $this->paginate('Thread', array(
'Thread.hidden' => 0,
'Thread.forum_category_id' => $id
),
array(
'Thread.created' => 'desc'
)
));
I'm not a Cake master, just a guess.
EDIT. Yes, thats right. Cake manual excerpt:
Control which fields used for ordering
...
$this->paginate('Post', array(), array('title', 'slug'));
So order is the third argument.
try
$all_threads = $this->Threads->find('all',
array(
'order' => 'Threads.created'
)
);
$saida = $this->paginate($all_threads,[
'conditions' => ['Threads.hidden' => 0]
]);
There are a few things to take note of in paginate with order. For Cake 3.x, you need :
1) Ensure you have included the fields in 'sortWhitelist'
$this->paginate = [
'sortWhitelist' => [
'hidden', 'forum_category_id',
],
];
2) for 'order', if you put it under $this->paginate, you will not be able to sort that field in the view. So it is better to put the 'order' in the query (sadly this wasn't stated in the docs)
$query = $this->Thread->find()
->where( ['Thread.hidden' => 0, 'Thread.forum_category_id' => $id, ] )
->order( ['Thread.created' => 'desc'] );
$this->set('threads', $this->paginate($query)
