Re: find all on complex model
You haven't provided any code other than a straight forward find query, we're likely to point you to book when this is the case, we need your code to help you also (like when I asked to see your associations). Here's an example based on the models and desired relationships you mentioned, this works for me but it assumes you've named your tables correctly like such: *lessons* id | tutor_id | ... *lesson_students* id | lesson_id | student_id *tutors* id | ... *students* id | ... The link is: http://pastie.org/private/vlod0ibqmwdf4geszb9fa It's much more simple to use contain over joins and hopefully you can see why. Also notice the 'with' part on the HABTM joins, writing this tells the association which model to use to join the tables, you can leave this blank and it will create a model on the fly. See more in the HABTM docs on this. Specifying one in advance this way allows you to access the join model easily and write methods within it, it's not required.

Also when saying adding something I NEED the code as please dont assume by adding containable I know what your talking about or the docs explain things.

Re: find all on complex model
I tried this and as expected it doesnt work and it cant work because HABTM
is a different case.
THis has to be the hardest framework to just get data to display from
tables. There just is no docs for a complete example.
$student= $this-Lesson-find('all', array('contain' = array( 'Student'
, 'Tutor')));

Re: find all on complex model
Again if this isn't working it's likely your tables or associations are
wrong, can you provide a pastie.

Re: find all on complex model
Hi Stephen,
Yes your example was a great effort and I solved the problem. The issue is
that I didnt add the fields argument in so this kept giving me undefined
errors.
I dont think your code will work as you dont specify fields.
Your models are setup like mine s that was really well done.
Also I need a find all as find first returns only 1 row.
$this-Lesson-recursive = -1;
$options['joins'] = array(
array('table' = 'lessons_students',
'alias' = 'LessonsStudent',
'type' = 'LEFT',
'conditions' = array(
'Lesson.id = LessonsStudent.lesson_id',
)
),
array('table' = 'students',
'alias' = 'Student',
'type' = 'LEFT',
'conditions' = array(
'LessonsStudent.student_id=Student.id',
)
),
);
$options['fields'] = array('Student.*','Lesson.*','LessonsStudent.*');
$options['conditions'] = array('Lesson.tutor_id' = 2);
$student=$this-set( 'student',$this-Lesson-find('all', $options));

find all on complex model
I just need to get the details from a find all across 4 associated tables.
I looked at the docs and I can get the data from 2 tables but not the other
tables.
I have a lessons table where I get the relevant tutor id rows to display
only. This works fine. I have a lessons-students table related to the
lessons table over the FK lessons id. From this lessons-students table I
then a field linked to another table.
lessons table (fk tutor_id but no student_id)
tutors table(linked to lessons table with tutor_id)
lessons_students table (linked with lessonID and has a studentID)
students table(linked with studentID from lesson-students table)
so if I get a row from lessons table I want the tutor name (from tutor
table and I can do this now), the student name via the studentID . This is
4 tables and this is proving a headache as the docs just do simple examples.
http://book.cakephp.org/2.0/en/models/retrieving-your-data.html
class LessonsController extends AppController {
$this-set( 'tutor',$this-Lesson-find('all', array(
'conditions'=array('Lesson.Tutor_id'=
1,'Lesson.id'='Lesson_Students.lesson_id') ) ));
view
?php
foreach ($tutor as $item):
echo 'trtd'. $item['Lesson']['id'].'/td';
// echo 'td'. $item['Tutor']['id']['username'].'/td';
echo 'td'. $item['Lesson']['tutor_id'].'/td';
echo 'td'. $item['Tutor']['last_name'].'/td';
echo 'td'. $item['Lesson_Student']['student_id'].'/td';
echo '/tr';
endforeach;
unset($item);

Re: find all on complex model
Looks like you are using recursive, you could try adding 'recursive' = 2 (or 3) to get deeper associations. Failing that you should look into Containable and HABTM or Has Many Through http://book.cakephp.org/2.0/en/core-libraries/behaviors/containable.html http://book.cakephp.org/2.0/en/models/associations-linking-models-together.html#hasandbelongstomany-habtm http://book.cakephp.org/2.0/en/models/associations-linking-models-together.html#hasmany-through If you're still having trouble if you could share your model associations and pr($item) on your query; On 30 August 2014 07:54, ajt jagguy...@gmail.com wrote: I cant get the student name to appear or student id -- Like Us on FaceBook https://www.facebook.com/CakePHP Find us on Twitter http://twitter.com/CakePHP --- You received this message because you are subscribed to the Google Groups CakePHP group.

Re: find all on complex model
$this-Lesson-find('all', array(
'contain' = array(
'Student' , 'Tutor')));
given that your models are named as the conventions suggest
You also need to attach the Containable Behaviour to your model
