Hi,
I'm new on Cakephp, I trying use hasMany Through relationships, after
read this, http://book.cakephp.org/view/1650/hasMany-through-The-Join-Model.
First of all, I have a model Subjects
Subject hasMany Student
Student belongsTo Subject
Now the problem, with hasMany through.
Course hasMany Student
Student hasMany Course
CourseMembership belongsTo Course, Student
In function add(), from subject controller, can't create N-students
with the existing N-courses.
But in function edit(), works fine with this form, in view:
echo $this->Form->create('Subject');
if($count < 3)
{
for($i=1; $i <= 2; $i++)
{
echo $this->Form->input('Student.' . $count .
'.CourseMembership.' . $i . '.course_id', array('type' => 'hidden',
'value' => $i));
echo $this->Form->input('Student.' . $count .
'.CourseMembership.' . $i . '.student_id', array('type' => 'hidden',
'value' => $student['student']['id']));
echo $this->Form->input('Student.' . $count .
'.CourseMembership.' . $i . '.hours', array('type' => 'hidden',
'value' => 10));
}
}
and controller:
if (!empty($this->data)) {
if ($this->Subject->saveAll($this->data)) {
foreach ($this->data['Student'] as $value) {
if(!empty($value['CourseMembership']))
$this->Subject->Student->CourseMembership-
>saveAll($value['CourseMembership']);
}
...
I need help.
Thanks.
