I'm trying to update a row in an associated table after a saving data in the current table. Say I have two tables, Listings and Queues. Queues has a foreign key of listing_id. So I've succesfully saved a new queue, which of course also includes the id of a listing, how can also update the status field of the Listing on the Listings table, say from from "paused" to "queued"?
See how my code looks like
$queue = $this->Queues->newEntity();
$queue->listing_id = $this->request->data['id'];
$queue->user_id = $this->Auth->user('id');
if ($this->Queues->save($queue)) {
$this->response->body("success");
$this->redirect(array('controller'=>'ListingsController','action' => 'changeStatus', $this->request->data['id'], "queued"));
}
Associations
Listings Table
$this->table('listings');
$this->displayField('name');
$this->primaryKey('id');
$this->addBehavior('Timestamp');
$this->belongsTo('Users', [
'foreignKey' => 'user_id',
'joinType' => 'INNER'
]);
Queues Table
$this->table('queues');
$this->displayField('id');
$this->primaryKey('id');
$this->belongsTo('Listings', [
'foreignKey' => 'listing_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Users', [
'foreignKey' => 'user_id',
'joinType' => 'INNER'
]);
This did the trick: $this->loadModel('Listings');
And then from there I could do a ->newEntity(), ->patchEntity() and/or ->save() on the Listings object using a WHERE clause on the query, like I would in the Listings controller.
E.g:
$this->loadModel('Listings');
$listing = $this->Listings->get($id);
$listing->status = "completed";
$this->Listings->save($listing);
Quite simple.

I am using CakeDC Users and as part of the registration I would like the registrant to choose some checkbox values that correspond to another Model in the application. I am able to get the form to load the choices just fine, but I am unable to get it to save to the join table even though I have added all of the associations and accessibilities where it would seem relevant. The form is displaying in a similar way to other areas where I am saving the same type of association with a different model.

In order for a "belongsToMany" association to work in this instance, both *Table.php files must have the relations listed as belongsToMany. Don't forget to make the field accessible in the Entities as well.
One also needs to place the associated array in the patchEntity function in the RegisterBehavior.php file.
UserTable.php (in CakeDC users)
public function initialize(array $config): void

$this->belongsToMany('Types', [

I have two tables category and product. I want to get details of product whose id are passed in conditions array of find query. The problem is when i pass condition as an array, it returns
Cannot convert value to integer
Secondly, if i debug it by passing only one id it returns category record, but it should return product record. Please help to solve my issue.
My code is as follows:
public function display()
{
$ids = array(1,2,3,4,5);
$c_List = $this->Products->Categories->find('all',array('conditions'=>array('Categories.category_id'=>$ids)));
$data = $c_List->toArray();
debug($data);
die();
}
Model - ProductsTable.php
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('products');
$this->setDisplayField('product_id');
$this->setPrimaryKey('product_id');
$this->belongsTo('Products', [
'foreignKey' => 'product_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Categories', [
'foreignKey' => 'category_id',
'joinType' => 'INNER'
]);
}
Model - CategoriesTable.php
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('categories');
$this->setDisplayField('category_id');
$this->setPrimaryKey('category_id');
$this->belongsTo('Categories', [
'foreignKey' => 'category_id',
'joinType' => 'INNER'
]);
}
When you are finding the records based on an array of ids, use IN in the condition clause.
public function display()
{
$ids = array(1,2,3,4,5);
$c_List = $this->Products->Categories->find('all',array('conditions'=>array('Categories.category_id IN'=>$ids)));
$data = $c_List->hydrate(false)->toArray();
pr($data);
die();
}
I need to build the associations like Group hasMany users and User belongToMany groups.
But I can't get the right result, it always use the wrong table instead groups_relations
My models:
class GroupsTable extends Table
{
public function initialize(array $config)
{
$this->setTable('groups');
$this->setDisplayField('title');
$this->setPrimaryKey('id');
$this->hasMany('Users', [
'joinTable' => 'groups_relations',
'foreignKey' => 'user_id',
]);
}
}
class UsersTable extends Table
{
public function initialize(array $config)
{
$this->table('user_users');
$this->belongsToMany('Groups', [
'joinTable' => 'groups_relations',
'foreignKey' => 'group_id',
]);
}
}
class GroupsRelationsTable extends Table
{
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('groups_relations');
$this->setDisplayField('group_id');
$this->setPrimaryKey('id');
$this->belongsTo('Groups', [
'foreignKey' => 'group_id',
'joinType' => 'INNER'
]);
$this->belongsToMany('Users', [
'foreignKey' => 'user_id',
'joinType' => 'INNER'
]);
}
}
And my table groups_relations:
id | group_id | user_id
I run query as:
$groupsWithUsers = $this->Groups->find('all', array(
'contain' => array('Users')
));
I can't understand how to tell to cake use my intermediary table and append reuslts to array.
joinTable is not a valid configuration key for a hasMany association. I think that you want to have Groups belongsToMany Users. Another clue about this is that hasMany is the "opposite" of belongsTo, while belongsToMany is it's own opposite. (That is, if A hasMany B, then B belongsTo A, but if A belongsToMany B, then B belongsToMany A.) Note that you will also want to change your GroupsRelations association with Users to belongsTo.
Is this code that was baked for you? Because it should know better. When I run into sticky association problems, I sometimes have Cake bake the model code for me, and then look at how the result differs from what I've written.
Rather than trying to use the relation the way you are doing why not just select from the relations table in the first place. This seems like the more Cake way of doing things. You can exclude the conditions clause if you want all data back.
$groupsWithUsers = $this->GroupsRelations->find('all', array(
'contain' => ['Users', 'Groups'],
'conditions' => ['Group.id' => $id]
)
);
After further looking into this I found something I have not used but seems to fit exactly what you need its a belongsToMany using an intermediary table. In your table file for the users you would add the following. A similar entry would be added to the group page.
$this->belongsToMany('Groups', [
'through' => 'GroupRelations',
]);
I'm making some tournament scoring software for my bike polo league. The goal is to match up teams in such a way that everyone gets a chance to play every other team before repeat matches start.
In my Match Entity class, I have a function called createMatches that should find all teams and associated matches. There is a HABTM relationship between matches and teams, with a join table. This relationship works fine - I've selected teams (contain matches) and matches (contain teams) in several controller methods, saved associations through forms, and so on. But even so, in this Entity function, I get the error "Teams is not associated with Matches. Could this be caused by using Auto-Tables? ...." and so on. Can anyone tell me what's wrong?
Here's the method in question.
public function createMatches($tournamentId) {
$team = TableRegistry::get('Teams', ['contain' => ['Matches']]);
$teams = $team->find('all', ['conditions' =>
['tournament_id' => $tournamentId],
'contain' =>
['Matches' =>
['fields' =>
['Matches.id']
]]]);
return $teams;
}
Here's the init function from Match.php:
public function initialize(array $config)
{
parent::initialize($config);
$this->table('matches');
$this->displayField('id');
$this->primaryKey('id');
$this->addBehavior('Timestamp');
$this->belongsTo('Rounds', [
'foreignKey' => 'round_id',
'joinType' => 'INNER',
'className' => 'SwissRounds.Rounds'
]);
$this->belongsToMany('Teams', [
'foreignKey' => 'match_id',
'targetForeignKey' => 'team_id',
'joinTable' => 'matches_teams',
'className' => 'SwissRounds.Teams'
]);
}
Here's the init function from Team.php:
public function initialize(array $config)
{
parent::initialize($config);
$this->table('teams');
$this->displayField('name');
$this->primaryKey('id');
$this->hasMany('Players', [
'foreignKey' => 'team_id',
'className' => 'SwissRounds.Players'
]);
$this->belongsToMany('Matches', [
'foreignKey' => 'team_id',
'targetForeignKey' => 'match_id',
'joinTable' => 'matches_teams',
'className' => 'SwissRounds.Matches'
]);
}
I don't believe I've touched either of those functions - they were both generated by cake bake.
Error message is quite exact, but not descriptive. It says that Teams is not associated with Matches.
Well, I tested this with minimal setup, with only difference, that I did not have my tables inside plugins. And no errors detected. So, I am pretty sure that CakePHP cant find your table classes inside SwissRounds -plugin for some reason.
If your tables are in a SwissRounds plugin, you should use plugin notation for the associations: $this->belongsToMany('SwissRounds.Teams', [... and $this->belongsToMany('SwissRounds.Matches', [...
Alright, I have some issues understanding how the associations are working, particularly belongsTo here is my setup:
Articles can have multiple Categories
Categories can belong to multiple Articles
so in my database i have 3 tables:
articles, categories and a join table articles_categories
Table/ArticlesTable.php:
public function initialize(array $config)
{
$this->addBehavior('Timestamp');
$this->table('articles');
$this->belongsTo('Users');
$this->belongsToMany('Categories', [
'through' => 'ArticlesCategories',
'alias' => 'Categories',
'foreignKey' => 'article_id',
'joinTable' => 'articles_categories',
'targetForeignKey' => 'category_id'
]);
}
Table/CategoriesTable.php:
public function initialize(array $config)
{
$this->table('categories');
$this->displayField('name');
$this->primaryKey('id');
$this->addBehavior('Timestamp');
$this->belongsToMany('Articles', [
'through' => 'ArticlesCategories',
'alias' => 'Articles',
'foreignKey' => 'category_id',
'joinTable' => 'articles_categories',
'targetForeignKey' => 'article_id'
]);
}
Table/ArticlesCategoriesTable.php:
public function initialize(array $config)
{
$this->belongsTo('Articles');
$this->belongsTo('Categories');
}
Now inside in the view action CategoriesController.php i can overview a particular category and i need to retrieve some articles related to that category.
What is the right way to do such a thing? Here is what i have:
public function view($id = null)
{
$category = $this->Categories->find('all',['limit'=>1])->where(['Categories.id' => $id])->contain(['Articles']);
$this->set(['category'=> $category]);
}
It kinda does the job but I'd also need to be able to limit the number of related articles..
you can modify the query object used to load the associated models:
$category = $this->Categories->find('all',['limit'=>1])
->where(['Categories.id' => $id])
->contain(['Articles' => function($q) {
$q->limit(10);
return $q;
}
]);
edit: or you can do
$category = $this->Categories->get($id,
[
'contain' => [
'Articles' => function($q) {
$q->limit(10);
return $q;
}
]);
or maybe if you want the Articles without the Category data you can use matching
$articles = $this->Categories->Articles->find()
->matching('Categories', function ($q) use $id{
return $q->where(['id' => $id])
->limit(10);
I did not tested the last one but I think something like that should work
But as you can see the complexity is more o less the same
