Hello Guys,
New Phalcon User Here.... I would like to know what method to count how many "unsaved" related Model is attached to Model. Example:
$parentModel = new Parent();
// Validate that $parentModel should have atleast 3 child models before saving.
$parentModel->save();This way:
if (count($parentModel->child) != 3) {
throw new Exception("error");
}Hello Andres... I appreciate your response... but unfortunately count($parent->child) doesn't show the number of child that has been attached to the parent. By the way.... in $parent->child = $childs, $childs is an array of newly created model (not yet saved to database).
This way:
if (count($parentModel->child) != 3) { throw new Exception("error"); }
So why count() won't be able to count an array of newly created model (not yet saved to database) if it's a simple array?
Let me have a simple example of my problem.
$children = array(
new Child(),
new Child(),
new Child());
$parent = new Parent();
$parent->child = $children;
echo count($parent->child); // should return 3, but it returns 0 instead
... inside $parent's validate function
return count($this->child) >= 3;You can see that I have no longer a reference to the children array but through $parent->child only. The problem is that $parent->child seems to not return the children array anymore. Upon successfully saving the $parent those children were also saved which is correct.
So why count() won't be able to count an array of newly created model (not yet saved to database) if it's a simple array?
I think I have the same problem like this one, but I dont know if this functionality has been provided right at this Phalcon version. https://forum.phalcon.io/discussion/919/-solved-kind-of-related-records-disappearing
Try doing it this way:
$parent->child = null;
$parent->child = $children;
