I have a problem with automagic and related model data. I have 4 models: Exercice, Ecriture, Ligne, Compte. Exercice hasmany Ecriture and Ecriture hasmany Ligne and Compte hasmany Ligne in two relation given by to different foreign keys. I want to use automagic to populate my form. So using $this->data, I give this array to the view:
Array
(
[Exercice] => Array
(
[id] => 1
[theme] => marchandises
)
[Ecriture] => Array
(
[0] => Array
(
[id] => 1
[exercice_id] => 1
[numero] => 1
[enonce] => Quelle est la dincee?
[Ligne] => Array
(
[0] => Array
(
[id] => 1
[ecriture_id] => 1
[compte_debit_id] => 2
[compte_credit_id] => 1
[montant_debit] => 23
[montant_credit] => 23
[libelle] => Achat de marchandises
[student_id] => 1
[CompteDebit] => Array
(
[id] => 2
[nom] => achat marchandises
)
[CompteCredit] => Array
(
[id] => 1
[nom] => caisse
)
)
)
)
Now if I want to access to the first level I simply use:
$this->Form->input('Ecriture.0.enonce');
And everything works fine!
But I can't access the seconde level using:
$this->Form->input('Ecriture.0.Ligne.0.libelle');
Why is that so? Can somebody help me?
Try the following:
Within Controller:
$this->data = array(
'Exercice' => array('column1' => 'value1', 'column2' => 'value2', etc.),
'Ecriture' => array(0 => array('column1' => 'value1', 'column2' => 'value2', etc.)),
'Ligne' => array(0 => array('column1' => 'value1', 'column2' => 'value2', etc.)),
)
As you can see, what I'm proposing is to place the data for associated models in the same level and NOT nested one within the other. So, by this approach, you can set the form elements like: $this->Form->input('Exercice.column1'); or $this->Form->input('Ecriture.0.column1');
By the way, now that I think about it, you should be able to populate the $this->data array automatically (for the form fields) by using read(), like: $this->data = $this->ModelName->read(null, $recordId). See more here in the cookbook.

I have 2 table booking and message , now I want to show booking request and message in inbox at a time.
$this->paginate = array(
'conditions' => $conditions,'limit' =>10,
'order'=>array('Booking.created'=>'DESC'));
$bookings = $this->paginate('Booking');

'order'=>array('MessageDetail.created'=>'DESC'));
$messages = $this->paginate('MessageDetail');

Thanks in advance.
Option #1:
Create a third Model named "BookingAndMessage". You could use the Model's afterSave method (on both Booking and Message) to create a duplicate record in your new model. You could then query the BookingAndMessage in the proper sort order.
Option #2: To solve the problem, as it stands, you will want to use PHP's usort function (also explained here PHP Sort a multidimensional array by element containing date).
<?php
$BookingsAndMessages = array_merge($bookings, $messages);
function date_compare($a, $b)
{
$modelKeyA = array_key_exists('Booking',$a) ? 'Booking' : 'MessageDetail';
$modelKeyB = array_key_exists('Booking',$b) ? 'Booking' : 'MessageDetail';
$t1 = strtotime($a[$modelKeyA]['created']);
$t2 = strtotime($b[$modelKeyB]['created']);
return $t1 - $t2;
}
usort($BookingsAndMessages, 'date_compare');
// Would sort the merged records by `created` date
?>
The downside to option 2 is, you are going to have to create rules for each field (and sort direction).
Perhaps you should Union your queries first, the Order.
$bookings = $this->Bookings->find('all', [
'conditions' => $conditions,'limit' =>10,
]);
$messages = $this->find('all', [
'conditions' => $conditions,'limit' =>10
]);
$data = $bookings->union($messages);
// This works if your first selected field is the one you want to sort.
$data->epilog('ORDER BY 1 ASC');

How do you modify a UNION query in CakePHP 3?
I have simple model relationship in CakePHP 1.3 with Categories -> Products
Category hasMany Products
There is slight difference between the data arrays which I get in the different controllers. The Product data is in the main product array when getting as associated model in the Categories controller and is separated when getting it in Products.
For Example to get 'Product1'
in Categories - $category['Product'][0]['title']
and in Products - $product[0]['Product']['title']
I would like to use same element for displaying the products. It does not matter which array scheme will be used just to be the same. And where is the right place to make the modification? I can modify those arrays after getting them, but don't think that it is the best option.
When I am in the Categories controller and get a category I get this:
// $this->Category->findById('12');
Array
(
[ProductCategory] => Array
(
[id] => 12
[title] => Category 1
[updated] => 2013-02-24 10:06:15
[created] => 2013-02-24 10:06:15
)
[Product] => Array
(
[0] => Array
(
[id] => 4
[parent_id] => 12
[title] => Product1
[updated] => 2013-02-24 10:17:01
[created] => 2013-02-24 09:12:59
)
[1] => Array
(
[id] => 6
[parent_id] => 12
[title] => Product2
[updated] => 2013-02-24 10:16:54
[created] => 2013-02-24 09:13:53
)
)
And when getting all the products inside the Products controller:
// $this->Product->find('all');
Array
(
[0] => Array
(
[Product] => Array
(
[id] => 10
[parent_id] => 12
[title] => Product1
[updated] => 2013-02-24 10:16:42
[created] => 2013-02-24 09:16:35
)
)
[1] => Array
(
[Product] => Array
(
[id] => 8
[parent_id] => 12
[title] => Product2
[updated] => 2013-02-24 10:16:47
[created] => 2013-02-24 09:15:39
)
)
)
)
One of your finds is a find('all') and the other is a findById() (which uses find('first')).
Both of these return data in a different format, since find('first') knows you only want one item, and find('all') is an unknown set of item(s).
Just use find('all') for both, but set your limit based on whether you need only one or more than one. Then, your data will be returned exactly the same.
Which Controller you retrieve your data from has no effect on the data returned. Which MODEL however, does - so just make sure you're doing your find from the same model.
Eg.
//in your ProductsController
$this->Product->find('all');
//in your CategoriesController
$this->Category->Product->find('all');
// in some other controller
$this->loadModel('Product);
$this->Product->find('all');
PS - BUT it's better if you don't do your "finds" in your Controller - make a method in your Model, and call it from your Controller(s) so instead of $this->Product->find(), it would be $this->Product->getProducts() (or whatever you want to call it). (read more about "fat models, skinny controllers" for reasons/examples...etc).
Dave is right, the difference is the method you're using... Even though you claim that associated data is always merged, your find on the 'Product' model is NOT associated data, so the format WILL always be different.
I've been here for a short while and I've already noticed that Dave knows his stuff. :)
I agree with the fat models/skinny controllers paradigm for clean, efficient code.
If you changed:
<?php
$this->Category->contain(array(
'Product'
));
$this->Category->find('all',
array(
'conditions' => array(
'Category.id' => $id // 12 for your OP.
),
'limit' => 1
)
);
?>
Should give you:
<?php
array
(
[0] => array
(
'Category' => array
(
[id] => 12
[title] => Category 1
[updated] => 2013-02-24 10:06:15
[created] => 2013-02-24 10:06:15
),
'Product' => array
(
[0] => array
(
...
),
[1] => array
(
...
)
)
)
)
?>
Please correct me if I am mistaken, thanks!
Or if you want "Products" to look like:
<?php
'Product' => array
(
[0] => array
(
'Product' => array
(
...
)
)
)
?>
when fetching data from the category model, you would need to fetch the associated data manually, e.g.:
<?php
$this->Category->contain();
$cats = $this->Category->find('all');
foreach ($cats as &$cat) {
$this->Category->Product->contain(); // You have to contain for each find.
$cat['Product'] = $this->Category->Product->find('all',
array(
'conditions' => array(
'Product.category_id' => $cat['Category']['id']
)
)
);
}
?>
I have two controllers: events and results. Events hasMany results, results belongsTo Events. I can save just fine, but when I go to edit, I can only get the information for the Event part of the form, to come in automagically.
I build the Results form info like this:
$option_number = 5;
for ($i = 0; $i < $option_number; $i++) {
echo $this->Form->select("Result.{$i}.object_id", $qual_options, array('empty' => false, 'class' => 'result-name'));
echo $this->Form->hidden("Result.{$i}.id");
echo $this->Form->hidden("Result.{$i}.type", array('value' => 'qual'));
echo $this->Form->hidden("Result.{$i}.action", array('value' => 'add')); ?>
}
In the backend, when I'm doing this to get the automagic population:
if ($this->request->is('get')) {
$this->request->data = $this->Event->findById($id);
}
It works just fine, but I can't figure out how to get it to show the Results. I've tried many things, most probable being:
$this->request->data['Result'] = $this->Result->findAllByEventId($id);
With that, I end up with a data structure like:
[Result] => Array
(
[0] => Array
(
[Result] => Array
(
[id] => 1
[object_id] => 1
[type] => qual
[action] => add
[amt] => 10
[event_id] => 1
)
)
[1] => Array
(
[Result] => Array
(
[id] => 2
[object_id] => 2
[type] => qual
[action] => add
[amt] => 1
[event_id] => 1
)
)
... etc.
)
)
Which definitely looks fishy, I just can't seem to manipulate it to work.
UPDATE I should have mentioned this; this is what my data looks like when I SAVE it, and I want to mimic this!
[Result] => Array
(
[0] => Array
(
[object_id] => 1
[type] => qual
[action] => add
[amt] => 0
[event_id] => 3
)
[1] => Array
(
[object_id] => 1
[type] => qual
[action] => add
[amt] => 1
[event_id] => 3
)
You can see that each numeric key after just has the information in it; instead, my numeric keys ALSO have an array INSIDE them name Result, and I have no idea how to make that go away properly! :} I could always loop through and build it in the format CakePHP wants, but I want to do it properly. And that single line above is what needs changing, but I have run out of ideas.
What about just using find('first') against the event? Since it's hasMany, it will return the Result model in a single [Result] key with many numeric keys.
$this->request->data = $this->Event->find('first', array(
'conditions' => array(
'Event.id' => $id
),
'contain' => array(
'Result'
)
));
This will return something like:
array(
'Event' => array(
'id' => 1,
'name' => 'event name'
),
'Result' => array(
0 => array(
'id' => 1,
...
),
1 => array(
'id' => 2,
...
)
)
);
You could unset the Event key if you needed to.
I have a page for editing records of the Venue model in my app. This page was working at some stage, but is now broken.
in the controller action, debugging $this->data gives the expected array of form values. However, in the Venue model, debugging $this->data in beforeSave gives only the values for fields from a related (HABTM) model, Category:
app/models/venue.php (line 89)
Array
(
[Category] => Array
(
[Category] => Array
(
[0] => 1
[1] => 2
[2] => 8
)
)
)
What could be happening to this data between the form being submitted to the controller action, and the call to beforeSave? Where should I be looking to debug this?
THanks
Edit - here's what's in $this->data in the controller (actual data changed to remove phone numbers, addresses etc).
app/controllers/venues_controller.php (line 63)
Array
(
[Venue] => Array
(
[id] => 19
[city_id] => 1
[user_id] => 130

[description] =>

And here's my code to save the data...
if (!empty($this->data)) {
if ($this->Venue->save($this->data)) {
$this->Session->setFlash('The venue has been saved','success');
$countryId = $this->Venue->City->field('country_id',array('id'=>$this->data['Venue']['city_id']));
if (!empty($this->data['Venue']['send_email'])){
$this->_emailVenue($this->Venue->id,'venue_added',$countryId);
}
$this->redirect(array('action' => 'index','city'=>$this->data['Venue']['city_id']));
} else {
$this->Session->setFlash('The venue could not be saved. Please, try again.','failure');
}
}
I think i found a solution to this but I am really unsure if this should be considered a "good" solution.
I backup the request data before the save and then restore it if it fails.
$temp = $this->request->data;
if ($this->Post->save($this->request->data)) {
}else{
$this->request->data = $temp;
}
Maybe a stupid question, but do you pass the content of controller $data to the model when you call the save() method ?
$this->Venue->save($this->data)
Are you trying to save an entry to the categories table at the same time? If so, you can use $this->Venue->saveAll($this->data) instead of save(). If you just want to save the Venue data, just pass that in to save() instead of the entire $this->data like this: $this->Venue->save($this->data['Venue']);
I have a bit more complex system...
I have
users model - hasMany Ads
ads model - hasMany "placads"
placads model - belongsTo Ads and Places
places model - hasMany placads
Now I run query like this:
$this->set(
'ad',
$this->User->Ad->find(
'all',
array(
'conditions' => array('Ad.user_id' => $this->Auth->user('id'))
)
)
);
and I am getting this without "Place" in * mark
[0] => Array
(
[Ad] => Array
(
[id] => 1
[user_id] => 1
[name] => bota
)
[Placad] => Array
(
[0] => Array
(
[id] => 1
[ad_id] => 1
[place_id] => 1
[count] => 10
*[Place] => Array
(
info about place
)*
)
[1] => Array
(
[id] => 2
[ad_id] => 1
[place_id] => 2
[count] => 20
*[Place] => Array
(
info about place
)*
)
)
)
What should I do to get something like I wrote into the * mark?
Thanks in advance!
use recursive:
http://book.cakephp.org/view/1063/recursive
$this->User->Ad->recursive = 2; // before find
alternatively:
$this->User->Ad->find( 'all',
array(
'recursive' => 2,
'conditions' => array('Ad.user_id' => $this->Auth->user('id'))
)
)
number 2 is an example, but should do in your case
2nd alternative:
