Okay, i've tried again, but i'm still not there. i think i need a little
more detail / hand-holding...
LISTING
Entity:
protected $_accessible = [
// All table columns = true, except id (not listed)
// ...
'attributes' => true
];
Table:
public function initialize() {
// Calls to table, primaryKey, displayField, belongsTo for other
tables...
$this->belongsToMany('Attributes', [
'foreignKey' => 'listing_id',
'targetForeignKey' => 'attribute_id',
'joinTable' => 'listings_attributes'
]);
// i thought all that could be handled automatically with
// $this->belongsToMany('Attributes', ['through' =>
'ListingsAttributes']); ?
}
ATTRIBUTES
Entity:
protected $_accessible = [
// All table columns = true, except id (not listed)
'listings' => true
];
Table:
public function initialize() {
// Calls to table, displayField, primaryKey
$this->belongsToMany('Listings', [
'foreignKey' => 'attribute_id',
'targetForeignKey' => 'listing_id',
'joinTable' => 'listings_attributes'
]);
// Again, i thought this could be done with
// $this->belongsToMany('Listings', ['through' =>
'ListingsAttributes']);
}
LISTINGS_ATTRIBUTES
Entity:
protected $_accessible = [
'listing_id' => true,
'attribute_id' => true,
'value' => true,
'listing' => true,
'attribute' => true,
];
Table:
public function initialize() {
// Calls to table, displayField, primaryKey
$this->belongsTo('Listings', ['foreignKey' => 'listing_id']);
$this->belongsTo('Attributes', ['foreignKey' => 'attribute_id']);
}
public function validationDefault(Validator $validator) {
$validator
->add('id', 'valid' ['rule' => 'numeric'])
->allowEmpty('id', 'create')
->add('listing_id', 'valid', ['rule' => 'numeric'])
->requirePresence('listing_id', 'create')
->notEmpty('listing_id')
->add('attribute_id', 'valid', ['rule' => 'numeric'])
->requirePresence('attribute_id', 'create')
->notEmpty('attribute_id')
->allowEmpty('value');
}
public function buildRules(RulesChecker $rules) {
$rules->add($rules->existsIn(['listing_id'], 'Listings');
$rules->add($rules->existsIn(['attribute_id'], 'Attributes');
return $rules;
}
Finally, ListingsController:
// Simplified add():
public function add() {
$listing = $this->Listings->newEntity();
if ($this->request->is('post')) {
$listing = $this->Listings->patchEntity($listing, $this->request->
data);
if ($this->Listings->save($listing)) {
// Flash->success & return redirect to index
} else {
// Flash->error
}
}
// various association data lookups for form data
// stuff like $attributes =
$this->Listings->findListByActive(true)->order('name');
// using magic finders
$this->set(compact(/* all the variables from the finders */));
}
Note that nowhere in the baked code is the *['associated' =>
['Attributes._joinData']]* option used as it is in the documentation. i
HAVE tried it in either *newEntity* or *patchEntity* calls, and both
together. No luck.
~whew~
The result of all this: the Listings record saves. But i'd already gotten
that far before. Still no ListingsAttributes records.
1. Your last post mentions removing validation for the two foreign key
columns in ListingsAttribute... So that means removing the *add*/
*requirePresence*/*notEmpty *calls for them?
2. i left my HTML/Form alone (see original post for what that looks
like), because i think there's a bug specifying a connection for cake bake
template... If the current documentation is accurate, that Form build
should work, correct?
3. i'm not sure what you meant by allowing id for attributes... i'm not
trying to create new attributes in this form, just write the joint table
records... Please clarify?
i hope i'm almost there... i will be SO happy when i can finally move
forward with this project again...
Thanks.
