Re: HABTM confusion
I have solved my problem. Basically I changed my code from
$advertisers = $this-paginate('TblDetail', array
('TblDetail.ap_advertiser LIKE'=%.$searchstr.%));
to
$advertisers = $this-paginate($this-TblDetail-TblAdCategory, array
('TblDetail.ap_advertiser LIKE'=%.$searchstr.%));
and I got the result I was looking for.

var $belongsTo = array('TblDetail','TblCategory');
}
In my controller I have the following statement:
$advertisers = $this-paginate('TblDetail', array
('TblDetail.ap_advertiser LIKE'=%.$searchstr.%));
where $searchstr is merely a value passed in from a form.
When I do a pr($advertisers) it shows the [TblDetail] Array as
expected. But the associated [TblCategory] shows an empty array even
though there is related TblCategory records.
Been trying to figure out where I have gone wrong. How do I get the
associated TblCategory record as well?
Any help is greatly appreciated.
Thanks.

HABTM confusion was: How to add item using HABTM relation
Hi Rob and thanks,
I did already what you show but the issue was on client side, I found
the solution : name the HTML element with data[Person][Person][0] on a
contract creation form witch is really not intuitive !
Now back the controller I have to delete a contract. I read here
http://bakery.cakephp.org/articles/view/add-delete-habtm-behavior
a very interesting article but I still don't understand the difference
between add and delete.
Add : if I put the right ID in data[Person][Person][0] it work fine
Delete look like an update, so the idea is to put in ata[Person]
[Person][0], ata[Person][Person][1], ... the ID you want to keep.
= this ends up with an update : fine but then, adding should remove
the previously associated element, how it can work ???

Your $this-data['Contract']['Person'] would be an array of the data
required for the person.
Since it appears you are doing this in your contracts controller, you
would need to get the ID for the person, then save the contract just
as you've shown.
I do something similar in my code: I have a signup sheet that uses
the currently logged in user's ID to add a row to the signup slots:
$this-User-create();
if ( $this-User-save($this-data) ){
$this-data['User']['user_id'] = $this-User-
getLastInsertId();
$this-data['UserSlot']['user_id'] = $this-data
['User']['user_id'];
$this-User-UserSlot-create();
if ($this-User-UserSlot-save($this-data
['UserSlot'])) {
$user_slot_id = $this-User-UserSlot-
getLastInsertId();
Basically I create the user, get the user ID, set the UserSlot's
user_id, and save the UserSlot ...
So as long as you set the data for the HATBM id's correctly, the rows
will be created.

Hi,
How to add an item to a HABTM relation ?
I have a Person and I have to add a Contract to that person.
Here are the data on a view :
data[Contract][type] : 12
data[Contract][name] : contract-AAaa
data[Contract][Person] : 26 // Should I put the person id here ?? or
something else ??
In fact, that contract added to person 26 could be later on added to
another Person, that's why its HABTM.
Currently, I'm trying to add a new contract to an existing person, so
the question, but later I'm not sure how to just link an existing
contract to an existing person ...
Here is the code on the controller to receive that data :
function add() {
if (!empty($this-data)) {
$this- Contract-create();
if ($this- Contract-save($this-data)) {
$this-set('returncode', 'Contract '.
$this- Contract-id.'
saved');
} else {
$this-set('returncode', 'ERROR :
Contract '.$this-
data['Contract']['name'].' not saved');
}
}
}
Thanks !

Re: HABTM confusion was: How to add item using HABTM relation
Because the HABTM relationship causes Cake to do its' magic, you have
to build the structure with all of the associated data you want to
save.
That article is showing you a behavior that will help you do that more
easily, by giving you methods to do so.
If you set debug to 3, you'll see the SQL that is executed, which will
help you understand what's going on.
