Wow, CakePHP really hasn't got this problem sorted.
After hours of searching I came across the solution below (which may or may not be outdated), but I'm having issues applying paginatior 'limit' => 10 or other ordering.
Any ideas what I'm missing?
My model:
public $hasAndBelongsToMany = array(
'Post' => array(
'className' => 'Post',
'joinTable' => 'tags_posts',
'foreignKey' => 'tag_id',
'associationForeignKey' => 'post_id',
'order' => array('Post.created DESC'),
'unique' => true
)
);
In my controller in view()
public function view($id) {
$this->Tag->bindModel(array('hasOne' => array('TagsPost')), false);
$this->set('tag', $this->paginate('Tag', array('TagsPost.tag_id' => $id)));
}
In my view I then had to change:
foreach ($tag['Post'] as $post)
to
foreach ($tag[0]['Post'] as $post)
Your view method should looks like:
public function view($id) {
$this->Paginate['limit'] = 10;
$this->Paginate['conditions'] = array('TagsPost.tag_id' => $id);
$this->Tag->bindModel(array('hasOne' => array('TagsPost')), false);
$this->set('tag', $this->paginate('Tag'));
}
Kindly ask if it not worked for you.
Tested with CakePHP 2.x
public function view ($id)
{
$this->paginate = array (
'limit' => 10,
'conditions' => array('TagsPost.tag_id' => $id)
);
$this->Tag->bindModel(array('hasOne' => array('TagsPost')), false);
$this->set('tag', $this->paginate('Tag'));
}

I've got the following models:
Run->hasMany ActualResult
ActualResult belongs to Status
When I view an ActualResult, Cake gets the corresponding Status without straight out of the box.
When I view a Run, I want to paginate the ActualResults. I have managed to get this to almost work with the following code in RunsController::view():
public function view($id = null) {
if (!$this->Run->exists($id)) {
throw new NotFoundException(__('Invalid run'));
}
$this->Run->contain ( 'Pack', 'User', 'Status');
$options = array('conditions' => array('Run.' . $this->Run->primaryKey => $id));
$run = $this->Run->find('first', $options);
$this->set('run', $run);
// Paginate the ActualResults
$this->paginate = array(
'contain' => array('Status'),
'order' => 'ActualResult.format',
'limit'=>5 ,
'conditions' => array('ActualResult.run_id' => $id)
);
$actualResults = $this->Paginator->paginate('ActualResult');
$this->set('actualResults',$actualResults);
}
The problem is that I get a warning:
Warning (512): Model "ActualResult" is not associated with model "Status" [CORE\Cake\Model\Behavior\ContainableBehavior.php, line 343
Something v. similar works for me in another model association, and as mentioned view() in ActualResultController works fine, so I am stumped.
Can anyone help?
Here are the model assocations:
In Run.php:
public $hasMany = array(
'ActualResult' => array(
'className' => 'actual_result',
'foreignKey' => 'run_id',
'dependent' => true,
'finderQuery' => 'SELECT ActualResult.*, Txn.name, Status.name FROM actual_results AS ActualResult, txns as Txn, codes AS Status WHERE ActualResult.run_id = {$__cakeID__$} and Txn.id = ActualResult.txn_id and (Status.code = ActualResult.status and Status.code_type = "ARS");'
)
);
In ActualResult.php
public $belongsTo = array(
'Run' => array(
'className' => 'Run',
'foreignKey' => 'run_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
'Status' => array(
'class`enter code here`Name' => 'Code',
'foreignKey' => 'status',
'conditions' => 'code_type = "ARS"',
'fields' => '',
'order' => ''
)
);
I have a database there have two table tutorials and districts tutorials has a one to one relation with district.Here in tutorials add page I am trying to get districts list.
So I have Coded in TutorialsController in add methods below code
public function add() {
if ($this->request->is('post')) {
$this->Tutorial->create();
if ($this->Tutorial->save($this->request->data)) {
$this->Session->setFlash(__('The tutorial has been saved.'));
return $this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The tutorial could not be saved. Please, try again.'));
}
}
$districts = $this->Tutorial->District->find('list');
$this->set(compact('districts'));
}
I have ensured
var $uses = array('Tutorial','District');
Relation code in Tutorial
public $belongsTo = array(
'Districts' => array(
'className' => 'Districts',
'foreignKey' => 'districts_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
Still I am facing error Call to a member function find() on a non-object in line code
$districts = $this->Tutorial->District->find('list');
I have used var $uses = array('Tutorial','District');
Why still this error is giving ?
Remove var $uses = array('Tutorial','District');(its unnecessary while models are associated) and edit as-
public $belongsTo = array(
'District' => array( // remove 's'
'className' => 'Districts',
'foreignKey' => 'districts_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
I've tried every simple cakedc search setup, and followed code samples from previous posts on this but it just won't seem to cooperate for me. I'm not sure, but there doesn't seem to be any search query generated with the search string, judging from a query log I have running on my database.
When I try to search, from /books/search, I get no results on a title I know is in the database and the URL changes to /books/index/title:sweet (I'm not sure if that is relevant).
Any help would be much appreciated.

public $actsAs = array('Search.Searchable');
public $primaryKey = 'isbn13';

'Override' => array (
'className' => 'Override',

Routes
Router::connect('/', array('controller' => 'books', 'action' => 'index'));
Router::connect('/index/*', array('controller' => 'books', 'action' => 'search'

I've renamed the search-master folder to Search and put it in my plugins directory and In my bootstrap.php I've loaded the plugin
CakePlugin::load('Search');
Fixed! Needed
$this->set('books', $this->paginate($this->Book->parseCriteria($this->passedArgs)));'
instead of
$this->set('books', $this->paginate());'
in the controller. Not sure why though..
For some reason i'm really having a hard time wrapping my head around HABTM associations. I learn best by watching someone do something and explaining why. Anyways, I have 2 tables I want associated, Drugs, and SideEffects. I've created the intermediate table drugs_side_effects(has no data right now). Does cake put the data in that automatically or do I need to do something? The 3.7.6.5 hasAndBelongsToMany (HABTM) from the book didn't specify.
I've set up the models correctly(I think) and am not sure how to proceed at this point. It seems pretty simple. I need to display side_effect from the SideEffects table in a Drug view. I think in the edit_french controller function i'll need something like
$side_effect = $this->Drug->SideEffect->read(
array('SideEffect.id','SideEffect.side_effect'), $id);
$this->set('side_effect',$side_effect);
but I feel like that won't work as expected. Or maybe there's a more efficient way? Any advice or help is appreciated.
Drug Model:
var $hasAndBelongsToMany = array(
'SideEffect' => array(
'className' => 'SideEffect',
'joinTable' => 'drug_side_effects',
'foreignKey' => 'drug_id',
'associationForeignKey' => 'side_effect_id'
)
);
}
?>
SideEffect Model:
var $hasAndBelongsToMany = array(
'Drug' => array(
'className' => 'Drug',
'joinTable' => 'drug_side_effects',
'foreignKey' => 'side_effect_id',
'associationForeignKey' => 'drug_id'
)
);
}
?>
Drugs Controller:
<?php
class DrugsController extends AppController {
var $name = 'Drugs';
var $helpers = array('Html','Form','Paginator');
var $paginate = array(
//'contain' => array('SideEffect'),
//'fields' => array('Drug.id', 'Drug.generic'),
'fields' => array('Drug.id', 'Drug.generic','Drug.date_altered'),
'limit' => 50,
'order' => array(
'Drug.generic' => 'asc'
)
);
function index() {
$data = $this->paginate('Drug');
$alldrugs = $this->set('drugs', $this->Drug->find('all'));
$this->set('drugs', $data);
$this->set('alldrugs', $data);
//$this->set('lessdrugs', $this->paginate());
$this->set('title_for_layout','List of all current drugs');
}
function edit_french($id = null) {
$this->Drug->id = $id;
$drug = $this->Drug->read(
array(
'Drug.id','Drug.generic','Drug.ahl','Drug.aap','Drug.rid','Drug.oral','Drug.mw','Drug.clinical_recommendations'
),
$id
);
$this->set('title_for_layout', 'Translate clinical recommendations - ' . $drug['Drug']['generic']);
$this->set('drug',$drug);
if (empty($this->data)) {
$this->data = $this->Drug->read();
} else {
if ($this->Drug->save($this->data)) {
$this->Session->setFlash('The drug has been updated.');
$this->redirect(array('action' => 'index'));
}
}
}
}
?>
You can pull the related data using ContainableBehavior. To do so, simply run a find on the Drug model and tell it to contain the associated SideEffect data.
$drug = $this->Drug->find('first', array(
'conditions' => array(
'Drug.id' => $id
),
'contain' => array(
'SideEffect'
)
));
You can also set the contain before using read() if you prefer.
$this->Drug->contain(array('SideEffect'));
$drug = $this->Drug->read(null, $id);
Using Containable allows you to gather all associated data in a single find() request.
Model
<?php
class Tonguetwister extends AppModel {
var $name = 'Tonguetwister';
//The Associations below have been created with all possible keys, those that are not needed can be removed
var $belongsTo = array(
'language' => array(
'className' => 'language',
'foreignKey' => 'language_alias',
'dependent'=> true
)
);
}
?>
Controller
<?php
class TonguetwistersController extends AppController {
var $name = 'Tonguetwisters';
var $uses = array('Tonguetwister', 'Language');
function index() {
$this->set('languages', $this->Language->find('all'));
}
function view($id = null) {
if (!$id) {
$this->Session->setFlash(__('Invalid tonguetwister', true));
$this->redirect(array('action' => 'index'));
}
$this->set('tonguetwisters', $this->Tonguetwister->find('all', array('conditions' => array('language_alias' => $id))));
}
}
?>
I only want to see languages on index() that have tongue twisters. How can I do this?
There might be a more efficient way, but here's how to pick only unique languages from the Tonguetwister table:
function index() {
$languageList = $this->Tonguetwister->find(
'list',
array(
'fields' => array( 'language_alias', 'language_alias' ),
'group' => 'Tonguetwister.language_alias',
'recursive' => -1
)
);
// $languageList is now an array that holds the language ids
$this->set(
'languages',
$this->Tonguetwister->Language->find(
'all',
array(
'conditions' => array(
'Language.id' => $languageList
)
)
)
);
}
By the way, you don't need to put Language into $uses. Since they have a relation set you can access the Language model with $this->Tonguetwister->Language.
You don't really need to do two SQL queries for this. If the tables are joined on "language_alias" you can do something like this:
function index() {
$this->Language->recursive = 0;
$this->set('languages', $this->Language->find('all', array(
'conditions' => array($this->Language->alias.'.language_alias' => $this->Tonguetwister->alias.'.language_alias')
));
}
You should just do one query that's going to join the tables properly.
