I am coverting my app over to cakephp 3.0 and I am having trouble finding an alternative to using neighbors in the find method.
I need to find the next record in the associated table and neighbors was a great way to do it.
//Open courses
$options = [
'conditions' => ['Employees.user_id' => 1, 'CoursesEmployees.completed' => false],
'limit' => 3,
'contain' => 'Employees'
];
$recentOpen = $this->CoursesEmployees->find('all', $options)->toArray();
// get next module for each open course
foreach ($recentOpen as $key => &$value) {
$currentModule = $value['CourseModule']['id'];
$neighbors = $this->CoursesEmployees->CourseModules->find(
'neighbors',
['field' => 'id', 'value' => $currentModule]
);
$value['CourseModule']['next_module'] = $neighbors['next']['CourseModule']['name'];
};
Another issue with the code I discovered is that $this->CoursesEmployees->find('all', $options)->toArray(); seems to return a complex array with everything cakephp uses to query the table and not the actual results like I got with cakephp 2. I added the ->toArray() as recommended with 3.0
Because I loathe "Answers" that simply point to a URL where you may or may not be able to decipher a half answer today, but could be gone tomorrow, here is my replacement custom finder:
// In src/Models/Table/ExampleTable.php
/**
* Find neighbors method
*/
public function findNeighbors(Query $query, array $options) {
$id = $options['id'];
$previous = $this->find()
->select('id')
->order(['id' => 'DESC'])
->where(['id <' => $id])
->first();
$next = $this->find()
->select('id')
->order(['id' => 'ASC'])
->where(['id >' => $id])
->first();
return ['prev' => $previous['id'], 'next' => $next['id']];
}
Called simply in the Controller:
// In src/Controller/ExamplesController.php
public function view($id = null) {
...
$neighbors = $this->Examples->find('neighbors', ['id' => $id]);
....
}
As explained here
there is no neighbors find method in cakephp 3.
But if you follow the flow of the issue you will find a custom finder to accomplish it, maybe it will work for you.

How can I create a custom Rule-Action which will successfully save a value as a replacement pattern for use in the other actions?
I got some very good help here on retrieving Product-Display information from a Product-Order.
As I said, the linked answer helped a great deal but the returned path data for the Product-Display comes back in the http://www.mysite/node/77 format. However, I really just need the numeric value only so I can load the node by performing a Fetch entity by id action supplying the numeric value and publishing the Product-Display node etc.
So, I implemented a custom action which will take the Product-Display URL(node/77) and return 77.
I copied the Fetch entity by id code and modified it so my returned numeric value can be saved and used in other Actions. The code is below:
function my_custom_action_info(){
$actions['publish_product_display_node'] = array(
'label' => t('Fetch product-display id'),
'parameter' => array(
'type' => array(
'type' => 'uri',
'label' => t('My Action'),
'options list' => 'rules_entity_action_type_options2',
'description' => t('Specifies the product-display url.'),
),
),
'provides' => array(
'entity_fetched' => array('type' => 'integer', 'label' => t('Fetched entity')),
),
'group' => t('Entities'),
'access callback' => 'rules_entity_action_access',
);
return $actions;
}
function publish_product_display_node($path = null){
$parts = explode('node/', $path);
return $parts[1];
}
function rules_entity_action_type_options2($element, $name = NULL) {
// We allow calling this function with just the element name too. That way
// we ease manual re-use.
$name = is_object($element) ? $element->getElementName() : $element;
return ($name == 'entity_create') ? rules_entity_type_options2('create') : rules_entity_type_options2();
}
function rules_entity_type_options2($key = NULL) {
$info = entity_get_info();
$types = array();
foreach ($info as $type => $entity_info) {
if (empty($entity_info['configuration']) && empty($entity_info['exportable'])) {
if (!isset($key) || entity_type_supports($type, $key)) {
$types[$type] = $entity_info['label'];
}
}
}
return $types;
}
function rules_action_entity_createfetch_access2(RulesAbstractPlugin $element) {
$op = $element->getElementName() == 'entity_create' ? 'create' : 'view';
return entity_access($op, $element->settings['type']);
}
As I said I copied the modified code so I don't claim to thoroughly understand all the functions aside from publish_product_display_node.
My code modifications work as far as setting the Product-Display URL token as the argument and also setting an entity variable label(Display NID) and value(display_nid).
The problem is when I check display_nid in newly created actions, the value is empty.
I need help figuring out the how to successfully save my entity value so I can use it in following Actions.
in the function publish_product_display_node, can you verify that you don't need to be returning $parts[0], instead of $[parts[1]?
It's just that Drupal paths are frequently in the form 'node/7' or 'taxonomy/term/6', and if you explode with 'node/' as the separator, you'd only have a single value which would start at index 0 for nodes...
So, just wondering if that would solve your issue...
I currently have this in my Model (Referer Model):
public function getReferers($type = 'today') {
if ($type == 'this_month') {
return $this->_getThisMonthsReferers();
} elseif ($type == 'today') {
return $this->_getTodaysPageReferers();
}
}
private function _getThisMonthsReferers() {
$today = new DateTime();
return $this->Visitor->find('all', array(
'fields' => array(
'Referer.url',
'COUNT(UserRequest.visitor_id) as request_count',
'COUNT(DISTINCT(Visitor.id)) as visitor_count',
'COUNT(UserRequest.visitor_id) / COUNT(DISTINCT(Visitor.id)) as pages_per_visit',
'COUNT(DISTINCT(Visitor.id)) / COUNT(UserRequest.visitor_id) * 100 as percent_new_visit'
),
'joins' => array(
array(
'table' => 'user_requests',
'alias' => 'UserRequest',
'type' => 'RIGHT',
'conditions' => array(
'UserRequest.visitor_id = Visitor.id'
)
)
),
'conditions' => array(
'Visitor.site_id' => $this->Site->id,
'MONTH(UserRequest.created)' => $today->format('m'),
'YEAR(UserRequest.created)' => $today->format('Y')
),
'group' => array(
'url'
)
));
}
The thing is that I how I would paginate this. It will be so easy if just copy my code out of the model and to the controller. The thing is I want the keep the query in my Model.
How is this supposed to be done in CakePHP?
A custom find type is one method. You can find more information here: http://book.cakephp.org/2.0/en/core-libraries/components/pagination.html#custom-query-pagination
To turn your _getThisMonthsReferers into a custom find, follow this http://book.cakephp.org/2.0/en/models/retrieving-your-data.html#creating-custom-find-types
For example:
// model
protected function _findThisMonthsReferers($state, $query, $results = array()) {
if ($state === 'before') {
$query['fields'] = ....
$query['joins'] = ....
return $query;
}
return $results;
}
// controller
public $paginate = array('findType' => 'thisMonthsReferers')
EDIT:
I think it should be :
public $paginate = array('thisMonthsReferers');
However the Solution I used derived from this answer is adding this to the method I am using
$this->paginate = array('thisMonthsReferers');
Since I don't want i used in all my actions. Then paginating the Model like this.
$this->paginate('Visitor);
Instead of returning the results of the find, just return it's array of options:
return array(
'fields' => array(
//...etc
Then use those options to paginate in the controller. More details on this answer of this similar question: Paginate from within a model in CakePHP
It still keeps the model fat (with any logic that might alter the conditions, joins, fields...etc), and the controller skinny, which just uses the returned array as paginate options.
Hi I'm currently working on a project and was wondering if it was possible to do two find functions in cakephp?
For example I am making a sports news website and I am grouping the news articles as top story, understory and headline.
What I want to do is retrive top stories so i can highlight these as the prominent story and then understory will be beneath as a lesser story and then headlines will be the least important.
This is what I have so far
function latestnews() {
$articles = $this->Article->find('all',
array('limit' =>3,
'order' =>
array('Article.date_created' => 'desc')));
if(isset($this->params['requested'])) {
return $articles;
}
$this->set('articles', $articles);
$articler = $this->Article->find('all',
array('Article.type' => 'topstory',
'Limit' => '1'
));
$this->set('articles', $articler);
}
however this doesn't seem to work, it doesn't limit the $articles function but instead echos all the data in the table.
in the view im doing a standard foreach statement to echo the data and I get thrown a undefined variable error.
Is what i am saying even possible or should I create different functions and then use them as elements?
Thanks for any input in advance!
You can bind the associationship with itself dynamically. Try this code:
function latestnews() {
$this->Article->bindModel(array('hasMany' => array('TopStory' => array('className' => 'Article',
'foreignKey' => false,
'conditions' => array('Article.type' => 'topstory')
),
'Highlight' .....
)));
$articles = $this->Article->find('all',
array('limit' =>3,
'order' => array('Article.date_created' => 'desc')));
if(isset($this->params['requested'])) {
return $articles;
}
$this->set('articles', $articles);
$articler = $this->Article->find('all',
array('Article.type' => 'topstory',
'Limit' => '1'
));
$this->set('articles', $articler);
}
Hope it will work for you.
#Arun Nope that didn't seem to work, I get this error, Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Article.type' in 'where clause' also I've tried to put it in an element with its own function and I then get thrown this error...
Notice (8): Undefined variable: data [APP/View/Elements/Articles/topstories.ctp, line 5]
Warning (2): Invalid argument supplied for foreach() [APP/View/Elements/Articles/topstories.ctp, line 5]
Notice (8): Undefined property: View::$Paginator [CORE/Cake/View/View.php, line 806]
Fatal error: Call to a member function prev() on a non-object in /Applications/XAMPP/xamppfiles/htdocs/kickoff/app/View/Elements/Articles/topstories.ctp on line 21
The controller code is the following...
function topstories() {
$this->paginate = array(
'conditions' => array('Article.type' => 'topstory'),
'limit' => 2,
'order' => array(
'date_created' => 'asc'
)
);
$data = $this->paginate('Article');
$this->set(compact('data'));
}
I find this error confusing as if I don't put this in an element and in a view instead it works perfectly! however in an element not so perfect :S
any ideas as to why this is the case??
Instead of using two find methods in one function I instead chose to simply create different functions and use them as elements for example...
function premiershiptopstory() {
$pltopnews = $this->Article->find('all', array(
'conditions' => array('Article.league' => 'premiership',
'Article.type' => 'topstory')));
if(!empty($this->request->params['requested'])) {
return $pltopnews;}
$this->set('article', $pltopnews);
}
However in the view you must request the action otherwise you will get thrown an error, to request the action simply use this line of code...
<?php $pltopnews = $this->requestAction('/Articles/premiershiptopstory');
Hope this helps others!
Cake handles pagination of a model with a simple $this->paginate(), but what should I use if I want to paginate a array of values?
The Scenario is like this:
$this->set('sitepages', $this->paginate());
This code in my index() returns an array like
Array
(
[0] => Array
(
[Sitepage] => Array
(
[id] => 13
[name] => Home
[urlslug] => home
[parent_id] => 1
[page_title] => Welcome to KIAMS, Pune
[order] => 1
)
)
[1] => Array
(
[Sitepage] => Array
(
[id] => 26
[name] => About Us
[urlslug] => aboutus
[parent_id] => 1
[page_title] =>
[order] => 2
)
)
[2] => Array
(
[Sitepage] => Array
(
[id] => 27
[name] => Overview of KIAMS
[urlslug] => aboutus/overview
[parent_id] => 26
[page_title] =>
[order] => 2
)
)
I retrieved the same data using $this->Sitepage->find('all') and then performed some manipulations as required and form a array which is very similar to the above one, but the ordering gets changed. I want to paginate this new array and pass it to the view. I tried
$this->set('sitepages',$this->paginate($newarray))
But the data is not getting paginated. Can some one please help with paginating the $newarray in CakePHP?
To paginate in CakePHP you need to pass select conditions to the paginate() call.
Other data manipulation should be done in afterFind(), in your model file.
If you don't need these changes to be done in every single retrieval, you might as well consider creating a new model file pointing to the very same table as the current one, and adding an afterFind() method to that new file.
I've just dealt with this same problem...
I found the only way is to use the paginate() function to handle all the logic, rather than passing it a custom array. However, this isn't as bad as it seems:
$this->paginate = array(
'limit' => 2,
'order' => array(
'Report.name' => 'asc'
),
'conditions' => array(
'Account.id' => $this->foo()
),
);
$reports = $this->paginate();
In this example, I'm paginating Reports - but some Reports will not be included, depending on which Account they belong to (Account has some relationship with Report, hasmany, etc.).
By writing $paginate inside your action, you can use a custom callback for the conditions array. So function foo() can be written in your controller (or shoved to model) and returns an array of valid Account IDs.
I found I could easily rewrite my custom logic in this function - keeping both me and the Cake paginator happy.
Hope that helps!
I'm using cakephp version 1.3 and it seems this one is working:
at controller:
$result = $this->Paginate('Event');
$results = $this->Task->humanizeEvent($result);
$this->set('events', $results);
and it seems to display as a normal paginated array, at the view (setup your pagination in view as normal).
The humanizeEvent function just edits a field on the results array, to make it a sentence based on other fields inside the array, and it seems to work properly.
$this->paginate($newarray) is the wrong way to paginate. The first parameter cannot be an array. It must be a model name. You may want to study pagination setup from the manual. This will order alphabetically:
var $paginate = array(
'limit' => 25,
'order' => array(
'Sitepage.name' => 'asc'
)
);
$this->set('sitepages', $this->paginate('Sitepage'));
I create a component checking the paginator code..
Is not the best thing, but It work for me.....
Controller
$slicedArray = array_slice($fullArray,($page - 1) * $this->PaginatorArray->limit ,$this->PaginatorArray->limit)
$this->params['paging'] = $this->PaginatorArray->getParamsPaging('MyModel', $page, $total,count($slicedArray));
$this->helpers[] = 'Paginator';
Component
<?php
/* SVN FILE: $Id$ */
/**
* Pagination Array Component class file.
* #subpackage cake.cake.libs.view.helpers
*/
class PaginatorArrayComponent {
var $limit = 40;
var $step = 1;
function startup( & $controller){
$this->controller = & $controller;
}
function getParamsPaging($model, $page, $total, $current){
$pageCount = ceil($total / $this->limit);
$prevPage = '';
$nextPage = '';
if($page > 1)
$prevPage = $page - 1;
if($page + 1 <= $pageCount)
$nextPage = $page + 1;
return array(
$model => array(
'page' => $page,
'current' => $current,
'count' => $total,
'prevPage' => $prevPage,
'nextPage' => $nextPage,
'pageCount' => $pageCount,
'defaults' => array(
'limit' => $this->limit,
'step' => $this->step,
'order' => array(),
'conditions' => array(),
),
'options' => array(
'page' => $page,
'limit' => $this->limit,
'order' => array(),
'conditions' => array(),
)
)
);
}
}
?>
There was a bug in find("count") and it returned incorrect count if the query resulted in records for only in group. This has been fixed click here
i have a little problem with cakephp
i have DB
measurers => id, title, color...
usages => id, measurer_id, value...
and i want to do something like
$this->paginate = [
'contain' => [
'MeasurerTypes',
'Usages' => function($q) {
return $q->find('latest');
}
],
'finder' => ['my' => $this->user['id']]
];
$this->set('title',__('My measurers'));
$this->set('measurers', $this->paginate($this->Measurers));
$this->set('_serialize', ['measurers']);
this is only example code, is there to find only one latest variable and no all list for that?
Check this:
http://book.cakephp.org/2.0/en/models/additional-methods-and-properties.html#model-getinsertid
Example:
$lastItem = $this->YOURMODEL->getInsertID();
Edit:
In CakePHP 3
http://book.cakephp.org/3.0/en/orm/retrieving-data-and-resultsets.html
$result = $articles->find('all')->all();
// Get the first and/or last result.
$row = $result->first();
$row = $result->last();
