Re: display data 3 tables
You are not doing something right. Can you show more code with the debugged output please? Cracking this and understanding what is happening will help you enormously with developing Cake apps from here.

Re: display data 3 tables
Yes this works without recursive
$contain = array('Teacher' => array('User'),'Student' => array('User'));
$this->set('tutor', $this->Tutorsession->find('first',array(
'conditions' => array('Teacher.user_id' => $id),
'contain' => $contain
)));

Re: display data 3 tables
With the Containable behaviour you should set recursive to -1. Recursion makes
the model automatically attache related models n deep (where n is your
recursion level) so can give unexpected (or at least uncontrolled) results.
When it is -1 it only returns the model associations you specify. The
Containable behaviour may well override that, but it's better to be safe than
sorry.

Re: display data 3 tables
You are referencing the $user variable when you have set a $tutor variable. Add
this to your view so you can inspect the shape of the $tutor variable and work
out how to access the key you are looking for:
die(debug($tutor));
It'll probably look something like this:
array(
'Tutorsession' => array(
'id' => 1,
'user_id' => 123,
'other_fields' => 'other_values',
'User' => array(
'id' => 123,
'username' => 'the_user_name'
)
)
)
If it does, you access the username with:
$tutor['Tutorsession']['User']['username']

Re: display data 3 tables
A couple of things...
Why find all when presumably there is only one expected teacher? The contain
statement doesn't go inside an array:
$this->set(
'tutor',
$this->Tutorsession->find(
'first',
array(
'conditions' => array('Teacher.user_id' => $id),
'contain' => 'User.username'
)
)
);

display data 3 tables
Hi,
I just want to display fields from 3 tables which I have checked on how to
do this and I am not clear on this. Examples I have found concentrate on 2
fields or keyed in conditions on multiple tables.
I have models all related in some way.
I want the username from a tutorsession table and the middle table is the
teacher table.
Tutorsession - related to teacher
Teacher -related to tutorsession and teacher
User= related to teacher
The tutorsession automatically gets rows from teacher table but not user
table. I have checked the docs below and I am not sure what to use here as
the below doesnt work but I dont get errors.
$this->set( 'tutor',$this->Tutorsession->find('all',array('conditions' =>
array('Teacher.user_id' => $id,'Teacher.user_id' =>
'User.id';
$this->set(
'tutor',$this->Tutorsession->find('all',array('conditions' =>
array('Teacher.user_id' => $id;
