I have a database with a table "projekte" (german word for projects).
Some of the projects have a relation to eachother.
So i would like to have a BTM relation.
I created a joinTable "projektverbindungen" with the following fields:
projekt_id
nebenprojekt_id
I found a similar question here: BelongstoMany relationship between a table and itself and i tried the answer of ndm, but without success.
Here is my ProjekteTable.php
class ProjekteTable extends Table {
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('projekte');
$this->setDisplayField('name');
$this->setPrimaryKey('id');
$this->hasOne('Projekteigenschaften', [
'foreignKey' => 'projekt_id',
'dependent' => true,
]);
$this->belongsToMany('Projekte', [
'foreignKey' => 'projekt_id',
'targetForeignKey' => 'nebenprojekt_id',
'joinTable' => 'projektverbindungen',
]);
}
}
Here ist my template (add.ctp)
<?php
echo $this->Form->create($projekt);
echo $this->Form->control('name', ['class' => 'form-control']);
echo $this->Form->control('projekteigenschaft.projektverantwortlich');
echo $this->Form->control('projekteigenschaft.beschreibung');
echo $this->Form->control('projekte._ids', ['options' => $projekte, 'multiple' => true]);
echo $this->Form->button(__('Submit'));
echo $this->Form->end();
?>
The first step, saving a project with a related project works as expected.
The id of the created project was saved as projektverbindungen.projekt_id and the id of the related project as projektverbindungen.nebenprojekt_id.
When i query a projekt without the relation to other projects like so:
$projekt = $this->Projekte->get($id, [
'contain' => ['Projekteigenschaften']
]);
the query looks like this:
SELECT Projekte.id AS `Projekte__id`, Projekte.name AS `Projekte__name`, Projekteigenschaften.id AS `Projekteigenschaften__id`, Projekteigenschaften.projektverantwortlich AS `Projekteigenschaften__projektverantwortlich`, Projekteigenschaften.beschreibung AS `Projekteigenschaften__beschreibung`, Projekteigenschaften.projekt_id AS `Projekteigenschaften__projekt_id` FROM projekte Projekte LEFT JOIN projekteigenschaften Projekteigenschaften ON Projekte.id = (Projekteigenschaften.projekt_id) WHERE (Projekte.id = :c0 AND (Projekte.deleted) IS NULL)
And the debug of the result looks like:
"id": "6862279f-8134-401f-86ff-9278a3bfa5c3",
"name": "My Project",
"projekteigenschaft": {
"id": "89d9e241-e700-4c31-9266-ee5717f2a0aa",
"projektverantwortlich": "Blisginnis, Ralf",
"beschreibung": ""
}
Everything works fine.
But when i add the projects to contain like so:
$projekt = $this->Projekte->get($id, [
'contain' => ['Projekteigenschaften', 'Projekte']
]);
The query looks the same like above, but the entity looks a bit different:
"Projekteigenschaften": {
"id": "89d9e241-e700-4c31-9266-ee5717f2a0aa",
"projektverantwortlich": "Blisginnis, Ralf",
"beschreibung": ""
}
Projekteigenschaften seems no longer to be a hasOne relation and "Projekte" gets totally ignored.
Anyone has an idea what i did wrong? Or should i prefer an other way of doing this?
edit after ndm´s comment
I tried defining the relationship like so:
$this->belongsToMany('Projektverbindungen', [
'class' => 'Projekte',
'foreignKey' => 'projekt_id',
'targetForeignKey' => 'nebenprojekt_id',
'joinTable' => 'projektverbindungen',
]);
and changed the add.ctp template like so:
echo $this->Form->control('projektverbindungen._ids', ['options' => $projekte, 'multiple' => true]);
But then it doesn´t save the relation.
I also tried to rename the joinTable to projekte_projekte. It didn´t seem to make any difference.
Then I tried to use the through-option, but the results of that were even worse.
So I continued trying to find a solution with the method described above.

In my bootstrap.php i have this:
Inflector::rules('plural', [
'/^(projekt)$/i' => '\1e',
'/^(projekteigenschaft|projektverbindung)$/i' => '\1en',
]);
Inflector::rules('singular', [
'/^(projekt)e$/i' => '\1',
'/^(projekteigenschaft|projektverbindung)en$/i' => '\1',
]);
After your recommendation I additionally added propertyName to the definition of the association:
$this->belongsToMany('Projektverbindungen', [
'class' => 'Projekte',
'propertyName' => 'Projektverbindungen',
'foreignKey' => 'projekt_id',
'targetForeignKey' => 'nebenprojekt_id',
'joinTable' => 'projektverbindungen',
]);
After that, the patched entity looks like this:
object(App\Model\Entity\Projekt) {
'name' => 'My Project',
'projekteigenschaft' => object(App\Model\Entity\Projekteigenschaft) {
'projektverantwortlich' => 'John Doe',
'beschreibung' => '',
'[new]' => true,
'[accessible]' => [
'projektverantwortlich' => true,
'beschreibung' => true,
'projekt_id' => true,
'projekt' => true
],
'[dirty]' => [
'projektverantwortlich' => true,
'beschreibung' => true
],
'[original]' => [],
'[virtual]' => [],
'[hasErrors]' => false,
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Projekteigenschaften'
},
'projektverbindungen' => [
'_ids' => [
(int) 0 => '1e28a3d1-c914-44be-b821-0e87d69cd95f'
]
],
'[new]' => true,
'[accessible]' => [
'name' => true,
'projekteigenschaft' => true,
'projekte' => true,
'projektverbindungen' => true
],
'[dirty]' => [
'name' => true,
'projekteigenschaft' => true,
'projektverbindungen' => true
],
'[original]' => [],
'[virtual]' => [],
'[hasErrors]' => false,
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Projekte'
}
But still no new entry in the table "projektverbindungen"
The last suggestion of ndm made the trick.
Now it works like expected. Thank you very much!
Here is the correct setup:
ProjekteTable.php
$this->belongsToMany('Nebenprojekte', [
'className' => 'Projekte',
'foreignKey' => 'projekt_id',
'targetForeignKey' => 'nebenprojekt_id',
'joinTable' => 'projektverbindungen',
]);
Here I used the property class instead of className, that has been the biggest issue.
Thats really embarrassing, because in the Cookbook is the correct name of that property:
https://book.cakephp.org/3/en/orm/associations.html#belongstomany-associations
Nevertheless, perhaps anyone else makes the same mistake and this thread can help.
The second thing is not to use the jointable`s name as the name of the association.
The rest is just straight forward...
Making the association accessible in the Entity Class (Projekt.php):
protected $_accessible = [
'name' => true,
'projekteigenschaft' => true,
'nebenprojekte' => true,
];
ProjekteController.php ("add" and "edit"):
public function add()
{
$projekt = $this->Projekte->newEntity();
if ($this->request->is('post')) {
$projekt = $this->Projekte->patchEntity($projekt, $this->request->getData());
if ($this->Projekte->save($projekt)) {
$this->Flash->success(__('flash message'));
return $this->redirect(['action' => 'index']);
}
$this->Flash->error(__('error message'));
}
$projekte = $this->Projekte->find('list');
$this->set(compact('projekt', 'projekte'));
}
public function edit($id = null)
{
$projekt = $this->Projekte->get($id, [
'contain' => ['Projekteigenschaften', 'Nebenprojekte']
]);
if ($this->request->is(['patch', 'post', 'put'])) {
$projekt = $this->Projekte->patchEntity($projekt, $this->request->getData());
if ($this->Projekte->save($projekt)) {
$this->Flash->success(__('flash message'));
return $this->redirect(['action' => 'index']);
}
$this->Flash->error(__('error message'));
}
$projekte = $this->Projekte->find('list')->where(['id !=' => $id]);
$this->set(compact('projekt', 'projekte'));
}
In the templates like add.ctp or edit.ctp:
echo $this->Form->control('nebenprojekte._ids', ['options' => $projekte, 'multiple' => true]);
If you use another language than english, don´t forget to set the correct inflection rules.
bootstrap.php:
Inflector::rules('plural', [
'/^(projekt|nebenprojekt)$/i' => '\1e',
'/^(projekteigenschaft)$/i' => '\1en',
]);
Inflector::rules('singular', [
'/^(projekt|nebenprojekt)e$/i' => '\1',
'/^(projekteigenschaft)en$/i' => '\1',
]);
I'm attempting to ->find('all') & contain the hasMany() Schedules which belongsTo() Services within the Services controller index method. A Service can actually have zero to many Schedules. Testing and experience from the Services view method has lead me believe that the issue is due to a DB field that is using a keyword. It's a field that I cannot see a need for at this time. Unfortunately, I don't have the ability to change database structure.
I attempted ->contain() and specified the fields I wanted, including the primary fields of the Schedules contain. The results were the same as Attempt #1 listed below. I have successfully used that in another model.
I attempted ->selectAllExcept($tableObj, ['FieldToExclude'])->contain(). I also attempted a beforeFind() within the SchedulesTable.php after research here but the function never seemed to be called.
I'm able to circumvent the issue in the view method by specifying the fields in a find directly to the Services table. However, this is not a viable option within the index method. I can do a loop to get the related records, but that's timely and defeats the fantastic benefits of Cake. Contain is awesome and is exactly what I need here.
Are the belongsTo & hasMany set up incorrectly? Am I missing something in the coding of $query? I've read through the documentation and I know that I am missing what is probably obvious to so many. I know I am getting to the point of frustration that won't let me think clearly. ;) I've even stepped away for a day hoping that would help.
Thank you in advance for any help that can be provided. It will be greatly appreciated.

Attempt #2 generates a SQL query error "Error: SQLSTATE[42000]: [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Incorrect syntax near the keyword 'Close'". Makes sense because the default behavior for a model is to select all of the fields.
$query = $this->Services->find('all')
->where($conditions)
->order([$sort => $direction])
->select($this->Services->Schedules);
Attempt #3. I tried to pass the table object to ->selectAllExcept() and exclude the problem field. The query builder builds the query incorrectly by using the fields from the Schedules table as if they were part of the Services table
$query = $this->Services->find('all')
->where($conditions)
->order([$sort => $direction])
->selectAllExcept($this->Services->Schedules, ['Close'])
->contain(['Schedules']);
Query built by the query builder. SrcvCallID, Line & Technician are all fields of the Schedules table, not Services.

Again, thanks for any assistance.
I have 2 tables "Descriptions" and "Phases", associated BelongsToMany using a join Table "DescriptionsPhases", as per Cakephp naming conventions. I've been struggling with this for the best part of a day now: I just cannot get the controller to save the id's of description and phase into my join table, which is basically just 3 columns, id / description_id / phase_id. Possibly more may follow for metadata.
Here is my code structure:
In Descriptions Table:
$this->belongsToMany('Phases', [
'foreignKey' => 'description_id',
'targetForeignKey' => 'phase_id',
'through' => 'DescriptionsPhases',
'saveStrategy' => 'append'
]);
In Phases Table:
$this->belongsToMany('Descriptions', [
'foreignKey' => 'phase_id',
'targetForeignKey' => 'description_id',
'through' => 'DescriptionsPhases'
]);
In DescriptionsPhases Table:
$this->belongsTo('Descriptions', [
'foreignKey' => 'description_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Phases', [
'foreignKey' => 'phases_id',
'joinType' => 'INNER'
]);
In Entities of all 3 of the above (for now):
protected $_accessible = [
'*' => true
];
In Descriptions Controller, add() method. The id for $descriptions->phases is hardcoded for now, just to reduce complexity:
public function add() {
$description = $this->Descriptions->newEntity([
'associated' => ['Phases']]);
if ($this->request->is('post')) {
// additional data to be saved in new description
$description->user_id = $this->Auth->user('id');
$description->designvariant = 666;
// Hardcoded integer TO BE SAVED in associated model (via join table)
$description->phases = [['id' => 5]];
$patch = $this->Descriptions->patchEntity($description, $this->request->getData(), [
'associated' => ['Phases']]);
debug($patch);
$save = $this->Descriptions->save($patch);
debug($save);
if ($save) {
$this->Flash->success(__('The description has been saved.'));
return $this->redirect(['action' => 'index']);
}
$this->Flash->error(__('The description could not be saved. Please, try again.'));
}
// pass arrays for dropdown menus
$this->set('trades', ($this->Descriptions->Trades->listLabels()));
$this->set('elements', ($this->Descriptions->Elements->listLabels()));
$this->set('allocations', ($this->Descriptions->Allocations->listLabels()));
$this->set(compact('description'));
$this->render();
}
I have debugged both after patchEntity and saveEntity, and get this data structure.
debug($patch);

The record is saved smoothly into the Descriptions Table, but it just won't save any associated data.
Am I missing something obvious?
Any help is gratefully received. Also, if you need more info, plz ask as it's my 1st post here :-)
Only entities are being saved, ie phases must hold an array of entities, not nested arrays. The nested arrays are what you'd pass to newEntity()/patchEntity(), where they would be converted into entities accordingly.
$description->phases = [
$this->Descriptions->Phases->get(5)
];

Suppose I have this find():
$categories = $this->Pages->Categories->find('active')
->select(['title', 'slug', 'page_count'])
->order(['title' => 'ASC'])
->cache('widget_categories')
->toArray();
Now, I want the slug field will be the array key.
For now I use a (horrible) loop:
foreach ($categories as $k => $category) {
$categories[$category->slug] = $category;
unset($categories[$k]);
}
Example of debug for $categories:
########## DEBUG ##########
[
'first-page-category' => object(MeCms\Model\Entity\PagesCategory) {
'title' => 'First page category',
'slug' => 'first-page-category',
'page_count' => (int) 1,
'[new]' => false,
'[accessible]' => [
'*' => true
],
'[dirty]' => [],
'[original]' => [],
'[virtual]' => [],
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'MeCms.Categories'
},
'sub-sub-page-category' => object(MeCms\Model\Entity\PagesCategory) {
'title' => 'Sub sub page category',
'slug' => 'sub-sub-page-category',
'page_count' => (int) 2,
'[new]' => false,
'[accessible]' => [

],
'[dirty]' => [],

This creates two problems:
it's a horrible method;
the data is cached before changing the array keys, then the same cycle must be performed each time.
One possible solution is to use Cache::read() and Cache::write(). Example:
$categories = Cache::read('widget_categories');
if (empty($categories)) {
//Find...
//Loop for changing keys...
Cache::write('widget_categories', $categories);
}
What seems to me the best solution, however, it is to use formatResults() with combine() methods. Example:
$categories = $this->Pages->Categories->find('active')
->select(['title', 'slug', 'page_count'])
->order(['title' => 'ASC'])
->formatResults(function ($results) {
return $results->combine('slug', function ($row) {
return $row;
});
})
->cache('widget_categories')
->toArray();
It's correct? Is there a simpler method and/or makes the code more readable?
Thanks.
i am trying to save additional data to a belongsToMany join Table.
I followed the instructions here
But they are just in case the entities already exist, because an id is used it seems. But my entities should be new created and additional join data should be saved.
My save data looks like this. Everything is persisted fine, except the additional field 'type_keys'
(int) 0 => object(Cloud\Model\Entity\MediaObject) {
'media_object_type_id' => 'image',
'title' => '1482842705_1_749145',
'relative_path' => '/optional_images/1/1/',
'extension' => 'jpg',
'size' => (int) 142683,
'original_title' => 'logo.jpg',
'_joinData' => [
'type_key' => 'optional_image_1'
],
'[new]' => true,
'[accessible]' => [
'*' => true
],
'[dirty]' => [
'media_object_type_id' => true,
'title' => true,
'relative_path' => true,
'extension' => true,
'size' => true,
'original_title' => true,
'_joinData' => true
],
'[original]' => [],
'[virtual]' => [],
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Cloud.MediaObjects'
}
Unfortunately just the joind ids in the join table are saved, but not the joinData field 'type_keys'
I would be happy if someone can give me a clue.
On further testing i found out that the join data gets overwritten when saving.
For your information: I am setting the media object join data in the beforeSave callback.
object(Cloud\Model\Entity\Touchpoint) {
'title' => 'test',
'user_id' => (int) 1,
'tp_image' => [
'name' => '',

'tmp_name' => '',
'error' => (int) 4,
'size' => (int) 0

'_joinData' => [

],
'[virtual]' => [],
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Cloud.MediaObjects'
}
],
'id' => (int) 8,
'[new]' => false,
'[accessible]' => [
'*' => true
],
'[dirty]' => [],
'[original]' => [],
'[virtual]' => [],
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Cloud.Touchpoints'
}
So i know it gets overwritten, but i am not sure how to do this the right way?
Ok i found the solution now.
Since i saw an entity is created as _joinData i created an entity myself and did set the property in the entity myself, this way the _joinData does not get replaced, but just enriched with the ids.
$joinTable = TableRegistry::get('MediaObjectsTouchpoints');
$newMediaObject->_joinData = $joinTable->newEntity();
$newMediaObject->_joinData->type_key = 'something';
$entity->media_objects[] = $newMediaObject;
