CakePHP 2.1 - Saving (and creating) multiple Join Models and associated models - cakephp

Question

My model relationship is as follows:
Student hasMany ClassStudent
Class hasMany ClassStudent
ClassStudent belongsTo Student
ClassStudent belongsTo Class
ClassStudent is a join model.
What I want to do is create Student(s), use an existing Class or create a new one, and create a join model record that links the Students and classes.
I want to do this all in one call to save (if this is even possible).
I have tried:
$data = array(
'Student' => array(
'0' => array( ... ), // Data in here
'1' => array( ... ),
...,
'n' => array( ... )
),
'Class' => array(
'class_id' => x // The class that I want the above students to be associated with
)
)
What I want to do is create n records of students and also add them to a class (possibly creating a class at the same time if the users wants to add a new one). I also want to create a join model record for each Student to the Class when I am creating the Student records.
Is this possible? I am using Cake 2.1.0 (today's stable release), and I have tried the different types of saveAll (saveAssociated and saveMany) with $options['deep'] = true.
Is it possible my data array is not in the correct format?
EDIT:
I have also tried:
$data = array(
'ClassStudent' => array(
'0' => array(
'Student' => array (...), // Data
'Class' => array(id => x) // The id of the Class the Student should be associated to
...,
'n' => array(
'Student' => array(...), // n-th Student
'Class' => array(id => x)
)
);
$this->saveAll($data['ClassStudent'], array('deep' => true));
In the above case, it successfully creates new Student records in the students table, but nothing is created in the join table.

Answer 1

saveAll (saveAll is a wrapper to saveMany and saveAssociated) is the right tool for the job. Take a look at the documentation for saveAll, I don't see any notes about it changing for 2.1. Having taking more time to read, here are some thoughts
First off, is there a type in your array structure. You have
'Class' => array ( 'class_id' => x )
If the Class is already defined and you are just wanting to add a student, then it would be
'ClassStudent' => array( 'class_id' => x )
With that said, CakesPHP ORM should allow you to use a saveAll with on a hasMany using a numerical index, so if assuming you have a typo, there follow might work for you
$data = array(
'Student' => array(
'0' => array( ... ), // Data in here
'1' => array( ... ),
...,
'n' => array( ... )
),
'ClassStudent' => array(
'class_id' => x // The class that I want the above students to be associated with
)
)
$this->ClassStudent->saveAll($data);
