Re: simple cakePHP question
What is the Cake way of deleting all the prefences for a User (but not the User itself) without having to loop over all the users prefences and call DELETE on the Preference model? Look in the API at the model class. Specifically, checkout the del method, and the _deleteHasMany method. There is a lot of stuff in the API that you won't find anywhere else! _deleteHasMany will loop through the preferences and delete each one. This would be the recommended way of deleting preferences since it would be done by the model. Of course the other way would be: $this-Preference-execute(DELETE FROM preferences WHERE user.id = .$user_id); But, if you have a beforeDelete method defined for the preference model, the execute sql method would skip that logic. sc --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Cake PHP group.

Quick and easy dispatcher for cron jobs
There has been quite a few threads about the best way to run cron jobs
when using CakePHP. I had to do this for my own application and I am
happy with the result so I want to share it with everyone. I can't take
all the credit for this as it's based on Jason Lee's post in the
thread:
http://groups-beta.google.com/group/cake-php/browse_thread/thread/ff3ad3c9e1e40aab/
It involves hacking the dispatcher so you can call controller actions
via the command line. What you do is make a copy of index.php in
/app/webroot/, scroll to the bottom and when you come to the line -
require CORE_PATH.'cake'.DS.'bootstrap.php'; - replaces everything
below it with the following code:-
// Dispatch the controller action given to it
// eg c:\php4\cli\php cron_dispatcher.php /mailouts/send
if($argc == 2) {
$Dispatcher= new Dispatcher();
$Dispatcher-dispatch($argv[1]);
}
What this means is you can call controller actions from the command
line, so for example to call the send action in your mailouts
controller you just create a cron job like this:
php cron_dispatcher.php /mailouts/send
Hope people find this useful.

Re: simple cakePHP question
Hi Joel, CakePHP makes this very easy for you. I'm assuming you've setup the models so that User hasMany Preference and Preference belongsTo User. To have it that CakePHP automatically deletes all the Preference entries when you delete the parent User just set 'dependent' to true in the hasMany array for User.

Re: hasMany query question
Hmmm... Me thinks you have a logic problem.
If Classification belongsTo Ad and Location belongsTo Ad then
searching by both Location.id and Classification.id at the same time is
redundant, since they would both share (at most) exactly one parent.
So if Classification belongsTo Ad , then Classification has only one
parent, and you can simply do this:
$this-Ad-Classifications-recursive = 3;
$data =
$this-Ad-Classifications-findById($this-data['Classification']['id']);
$ad = $data['Ad'];
Or if Location belongsTo Ad , then Location has only one parent, and
you can simply do this:
$this-Ad-Location-recursive = 3;
$data = $this-Ad-Location-findById($this-data['Location']['id']);
$ad = $data['Ad'];
Back to the logic problem... If one ad can have more than one
classification, and many adds can share the same classification, then
you are not using the correct relationships. Based on your question, I
suspect you should be using hasAndBelongsToMany. If you think this is
possible, read the model chapter of the cake manual again:
http://manual.cakephp.org/chapter/models Otherwise, ignore my
response.

Querying Question
Hi, This might not necessarily related to cake, but I would like to know what's the best way to do this. I have a users table (that has user_id, first_name, last_name...etc) And a profile table (profile_id, user_id, country) And a friends table which has (friend_id, user_id profile_id) Now on the profile page, for that particular profile, I query friends table to get the user_id's of all the friends and display their photos, because all photos are user_id.jpg, but now I want to display the user's first name as well but that is in the user's table. I have 2 approaches - 1) Put user_name also in the friends table 2) Loop through all friends and for every entry go to the user table to get the user first name What do you guys suggest? 2nd one will have lots of select queries whereas first one would just duplicate data?

RE: Querying Question
From database normality PoV, you should stick with your current structure (approach 2). Complexity of SELECT query should belong to CakePHP engine, not yours. If you have defined the Model Association correctly, CakePHP will also retrieve related tables, so you shouldn't worry about how to query. From what I understand, you will have the following associations: User hasOne Profile (and Profile belongsTo User) User hasMany Friend (and Friend belongsTo User) If you queried (findAll) a Profile, CakePHP will also fetch related User, Friends, and Friends' User. CakePHP have a recursive limit of 3, that means you can only get 3 associated tables from the current one. This is good enough for your problem. -Original Message- From: cake-php@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Mandy Sent: 19 Nopember 2006 19:24 To: Cake PHP Subject: Querying Question Hi, This might not necessarily related to cake, but I would like to know what's the best way to do this.

Re: Querying Question
I would definitely avoid the duplicate data scenario.
I have a users table (that has user_id, first_name, last_name...etc)
And a profile table (profile_id, user_id, country)
And a friends table which has (friend_id, user_id profile_id)
Why does the friends table have profile_id?
If friend_id is pointing to a record in the users table, then there
would be no need to store the profile_id twice.
If friend_id is NOT pointing to a record in the users table, then I
have misunderstood your question and you can ignore the rest of this
post.
If I understand your problem correctly, you need a hasAndBelongsToMany
association which relates the users table to it's self.
Try renaming your friends table to users_friends, and then add this
association to your User model.
var $recursive = 2;
var $hasAndBelongsToMany = array('Friend' =
array('className'= 'User',
'joinTable'= 'users_friends',
'foreignKey' = 'user_id',
'associationForeignKey'= 'friend_id',
'conditions' = '',
'order'= '',
'limit'= '',
'uniq' = true,
'finderQuery' = '',
'deleteQuery' = '',
)
);
if it works correctly (it worked for me when I tested it) you should
find the friend records in the data returned from the User model.
So if your controller code looks like this:
$this-set('user', $this-User-read(null, $id));
Then your view code might look like this:
?php if(!empty($user['Friend'])):?
UlFriends
?php foreach($user['Friend'] as $friend): ?
li?php echo $friend['id'].' ' .$friend['first_name']?/li
/Ul
?php endforeach; ?
?php endif; ?
hasAndBelongsToMany associations can seem rather complicated if you're
not used to them. If you have trouble getting this code to work, you
should probably read the models chapter of the cake manual, and perhaps
some hasAndBelongsToMany tutorials.
I have seen this question before, but I don't think it was answered, so
please let me know it this works for you.
Good luck,
sc

Re: Self recursion problem
Go to the API and checkout the Model::findAllThreaded() method. It does exactly what you are looking for. In your controller, you should be able to replace findAll with findAllThreaded. findAllThreaded will look for a parent_id field, if it finds one, child objects (sub-menus in your case) will be put in a separate array named children. Use the debug output to see how the data is structured. sc On Nov 19, 8:30 am, voriux [EMAIL PROTECTED] wrote: Hi people, I would like to ask a noob question how to model this situation?

Re: hasMany query question
Thanks for the reply. Let me expand abit. Model 'A' hasMany 'B' and
hasMany 'C'. I want to find the instance of model 'A' that has a spicific
'B' AND a specific 'C'. Now here's the part I left out. Model 'D' hasMany
'B' and 'E' hasMany 'C'. So, a given 'B' or 'C' belongs to only one 'A',
but also to only one 'D' or 'E' (as apposed to many 'A', 'D' 'E's).
Basically, 'A' hasAndBelongsTo 'D' and 'E', but the join tables are too
complex for cake's standard habt relationship to work (there's more in there
than I've described). So I created a model for the join tables and made the
change in the relationships.
So, one 'Ad' can have many 'Classifications', and many 'Locations', but I'm
looking for the specific 'Ad' that has a 'Classification' AND a 'Location'
containing the correct 'Category' and 'City' respectively.
However, the question remains, is it posible to use a feild from a table
associated with a hasMany relationship in the findAll($conditions) array?
What I've recently decided to try on monday is to do:
$var1 = $this-Ad-Location-findAll($conditions);
$var2 = $this-Ad-Classification-findAll($conditions);
$ads = array_intersect($var1, $var2);
Although that seems like a weird way to do it. Then again, maybe my whole
concept is the weird way to do it in the first place.
