Re: Model Association and Find
Since HABTM data is constructed as separate SQL statements, and not a JOIN, you cannot add conditions to the query directly. There are ways to get the data you want, though.

Re: Model association problem - not getting expected array using $hasMany and $belongsTo association
Everything appears to be correct. Try deleting any files in
app/tmp/cache/models/ if you haven't already. And set debug to 2, both
so the models won't be cached and so you can see what queries are
being run.

Re: Model Association 'chain'
Take a look in the CakePHP manual at the Containable behaviour, which
will give you the possibility to specify how deep you want to go in
your relationships when retrieving your data.
http://book.cakephp.org/view/474/Containable
Also it will make your life easier :)
Enjoy,

Re: Model Association 'chain'
In the case of viewing a record, Containable is very much your friend. Saves you so much time. If paginating deep associations, espcially if you want a condition on model 3 or 4, then you need to get your head around ad-hoc (forced) joins. http://book.cakephp.org/view/86/Creating-and-Destroying-Associations-on-the-Fly Teknoids blog is a must read if you are to get your head around forcing joins, and you will eventually need his advice on HABTM too, saved me edless hours of pain. http://teknoid.wordpress.com/2008/07/17/forcing-an-sql-join-in-cakephp/ HTH Paul.

var $hasMany = array(

Result:

SQL Error: 1054: Unknown column 'Category.width' in 'where clause'
That seems clear if you make a look on the generated Query:
SELECT ... FROM 'zones' AS 'Zone' WHERE (('Category'.'width' =
'Zone'.'width') AND ('Category'.'height' = 'Zone'.'height'))
No Join occurs - but why? Can anybody help me out?
I appreciate any help on this issue.
Regards.

Re: Model association problem
The database table names ought to be plural, viz: MEDICINAL_DEVICES, USERS etc. Cake is intelligent enough to handle plurals such as COMPANIES (COMPANY). In the model definitions, the model will be the capitalised singular version of the tablename, e.g. User Foreign keys are singular, e.g. user_id All these things can be changed where required, but will generally break the bake if they don't follow the convention. see: http://book.cakephp.org/view/24/Model-and-Database-Conventions --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups CakePHP group.

For instance, the console does recognize all the tables from the database, but when it's triying to detect associations it comes up with the result like on the end of this post or just skips to 'Look okay?'. It the noted example on end of the post, I manage to create a complete model (with association to user), but association among other models fails. So my question's are: 1. Am I breaking some convetions and it's not working? 2. Could it be that I'm using InnoDB type? 3. Anything else? Any kind of sugestions is appreciated. Thnx. Possible Models based on your current database: 1. DocumentsDevice 2. Group 3. InvestigationalSite 4. Investigator 5. Manufacturer 6. MedicinalDevice 7. MedicinalProduct 8. ReportDevice 9. ReportProduct 10. SoaDevice 11. SoaProduct 12. User Enter a number from the list above, type in the name of another model, or 'q' to exit [q] 2 Would you like to supply validation criteria for the fields in your model? (y/n) [y] n Would you like to define model associations (hasMany, hasOne, belongsTo, etc.)? (y/n) [y] y One moment while the associations are detected. --- Please confirm the following associations: --- Would you like to define some additional model associations?

Re: Model Association Not Creating Query Joins
Start from the AccountAlert model rather than the Alert model. Use
contain as well.
$alert_ids = $this-AccountAlert-find (
'all',
array (
'contain' = array(),
'conditions'= array (
'AccountAlert.account_id' = $account_id
),
'fields'= array('alert_id'),
)
);
You should also use contain to restrict the number of models involved
in each query. Containing an empty array (or an empty string, I can't
remember) will tell your query to not join any other models.

I have an Alert model, an Account model and an AccountAlert model:

AccountAlert has several other defining fields, so it has its own

more than a simple linking table. It has foreign keys to the alerts
and accounts tables (alert_id and account_id, respectively).
From AccountModel, I'm trying to retrieve all of the Alerts for a
given Account. If I try a simple find:
$this-Alert-find ( 'all' )
I get each Alert and each AccountAlert that has that alert. If,
however, I try to restrict by the account_id then I get an unknown
column error:
$alert_ids = $this-Alert-find (
'all',

'conditions' = array (
'AccountAlert.account_id' = $account_id

Looking at the debug SQL, no join is being created. Since the model
associations are intact (I assume this is the case since the simple
find() returns data for both models), should CakePHP be building the
join automagically and, therefore, understanding the
AccountAlert.account_id syntax in my condition?
Even being relatively new to CakePHP, it still seems like I should
have run into this before, but I can't remember having seen this. Any
push in the right direction would be much appreciated.

Thanks, everyone. Has it always been like this? For some reason, I
would have sworn that in the past I've done something like this:
$this-AccountAlert-find (
'all',
array (
'conditions' = array (
'AccountAlert.active' = 1
),
'order' = 'Alert.priority'
)
);
Note the different models being used in the conditions and order
parameters. Has that never been possible?
Thanks again for the help. I'll definitely be digging into the
containable behavior.

Re: Model Association Not Creating Query Joins
In cases like what you are looking at it tends to work a bit better if
you rather do the find on the model you want to filter.
Something like:
$alert_ids = $this-Alert-AccountAlert-find (
'all',
array (
'conditions'= array (
'AccountAlert.account_id' = $account_id
),
'fields'= array('Alert.id'),
)
);
That might work (Sorry, sitting at university, can't test).
Otherwise you can try the containable behaviour, that should be able
to do what you wish.

'joinTable' = 'products_sizes',

Re: Model association
Hi guys, thanks for your replies.
Right now, im my 'add' view of products, im getting a multiple select
for the sizes, where i can select which sizes are available for that
particular product, thats fine. The problem is that i need a stock
number for each of this available sizes, so a multiple select wont
work for me.
An example would be:
[ (checkbox) ] Small --- Stock [ input (a number) ]
[ (checkbox) ] Medium --- Stock [ input (a number) ]
[ (checkbox) ] Large --- Stock [ input (a number) ]
So when i hit submit on the form, i can see the selected sizes for
that product along with the stock value for each one. Thats what i
need to achieve, but i dont know how to make the associations, neither
the necessary models for this to work.

I explain how with work here, I think this should be good to get
you started:
http://teknoid.wordpress.com/2008/07/03/notes-on-cakephp-habtm-part-1-the-basics/
Also, just a hint... cake can easily create checkboxes for you
(instead of multi-select).
Just tell it to use 'multiple'='checkbox' in your input() tag.

Re: Model association
Ok guys, it seems i have the data (extra field 'stock' in the
association table) in $this-data when i edit a Product, something
like this, so the association table is auto-modelized:
[Size] = Array
(
[0] = Array
(
[id] = 2
[name] = S
[position] = 2
[created] =
[modified] =
[ProductsSize] = Array
(
[id] = 248
[product_id] = 4
[size_id] = 2
[stock] = 0
)
)
[1] = Array
(
[id] = 5
[name] = XL
[position] = 5
[created] =
[modified] =
[ProductsSize] = Array
(
[id] = 249
[product_id] = 4
[size_id] = 5
[stock] = 0
)
)
)
But i dont know how to update that stock value, i think the idea is,
like i explained before to get and input field for each row, so i can
specify the stock number for that particular association, in other
words, be able to fill that extra information.

Re: Model Association Query....stumped
I've done the following:
Clipranking Model:
function findClipByRank($site_id){
return $this-query(SELECT Clipranking.rank,
Clipranking.site_id,
Clipranking.required, Clip.id, Clip.name, Clip.length FROM
cliprankings AS Clipranking, clips AS Clip WHERE Clipranking.site_id =
$site_id AND Clipranking.clip_id = Clip.id);
}
And calling in my controller works fine: $clip = $this-Site-
Clipranking-findClipByRank($id);
In my short experience with Cake, it seems that there would be a more
Cake-ish way to accomplish this. I'm a noob here so, it's probably
obvious.

Is this not inconsistent? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Cake PHP group.

Re: Model Association 'limit' not working
Did you try turning on debug mode and see how the SQL statement looks
like? Try running the sql statement manually and you should be able to
track where the problem is.

Re: Model association issue
Hi Brian,
You can´t create 2 associations with the same name. You can't say a
user HasOne Venue and User HABTM Venue - if you don´t give you
associations unique names the data for both will get mixed together
(with confusing results as you have seen).
Let me clarify what that means before you say but I need those
associations ;)
Try something like this:
?php
class User extends AppModel
{
var $name = 'User';
var $hasOne = array('MainFan' = // Changed
array('className'= 'Fan',
'conditions' = '',
'order'= '',
'dependent'= true,
'foreignKey' = 'user_id'
),
'MainArtist' = // Changed
array('className'= 'Artist',
'conditions' = '',
'order'= '',
'dependent'= true,
'foreignKey' = 'user_id'
),
'MainVenue' = // Changed
array('className'= 'Venue',
'conditions' = '',
'order'= '',
'dependent'= true,
'foreignKey' = 'user_id'
),
'MainPromoter' = // Changed
array('className'= 'Promoter',
'conditions' = '',
'order'= '',
'dependent'= true,
'foreignKey' = 'user_id'
),
);
var $hasAndBelongsToMany =
array('Fan','Artist','Venue','Promoter'); // unchanged
}
If the hasOne is to specify some special relationship, I think that in
1.2 you have/will have the possibility to add fields to your join table
such that you could then have only a HABTM with one of the defined
relationships having the type Main (or whatever is the actual
meaining of the hasOne as defined here).
Rather than dribble on, after renaming your associations - does that
work?
HTH,
AD7six
PS. this is all based upon looking at your debug data and glancing at
the source - so it could be wrong.

Re: Model association issue
Scaffolding can display this for you, it's a great tool! You can view the output here: http://www.myclubbersguide.com/users It contains the queries being used as well as the print_r() of the object(s). The code for the models was in the first email/post in this thread. As far as i understand it, scaffolding is recursive.

Re: Model association
I'm having a similar problem simply trying to add comments to posts.
I've tried to get a list of comments that would be associated with a
single post by adding
$this-set('comments', $this-Comment-findAll(WHERE post_id =
'$id'));
to the view() function under posts_controller.php but that line returns
Fatal error: Call to a member function on a non-object. I don't
fully understand how to go about viewing and manipulating data like
comments that are fully dependent on posts. I shouldn't have to set up
individual controllers and views for them because I don't want users to
have to go to /comments to view them.
Can anyone give a little insight into this as well as the original
question?

Re: Model association
Gotta use model assocations - it makes this sort of thing so much nicer.
http://manual.cakephp.org/chapter/6
Looks like your Comment belongsTo Post, and probably Post hasMany
Comment.
Give the manual a look, and let me know if you have questions on it.
