I am building a new app based on multiple databases with many tables which don't follow any Cake conventions. I want to use CakePHP but I'm not sure if it's possible without the database in a Cake format.
Problems include:
Tables not named as Cake expects
Primary keys are not necessarily named id (e.g. it might be order_id)
Foreign keys are not necessarily named like other_table_id
Changing the database tables is not an option.
Is it possible to manually configure the schema in each model so that Cake will then know how the model relationships need to work? Or should I just give up on using Cake?
yes. you can still use CakePHP in your case.
Check out various Model attributes to fit your needs
http://book.cakephp.org/2.0/en/models/model-attributes.html.
e.g.
public $useTable = 'exmp' can be used to configure what table to use.
public $primaryKey = 'example_id'; can be used to configure the primary key's name
**Try this code sample............**
More detail here http://book.cakephp.org/2.0/en/models/model-attributes.html
<?php
class Example extends AppModel {
// Name of the model. If you do not specify it in your model file it will be set to the class name by constructor.
public $name = 'Example';
// table name example
public $useTable = example;
// example_id is the field name in the database
public $primaryKey = 'example_id';
}
?>

I have a simple problem and I don't know how to solve it.
I work with an existing database, where tables don't match with cakePHP conventions, and I have to make cakePHP work with it.
For example, I have a table named "ItiConf" in sql db (instead of iti_confs by convention).
My model ItiConfModel.php :
class ItiConf extends AppModel {
}
My controller ItiConfsController.php :
class ItiConfsController extends AppController {
//...
}
I tried to make my own Inflector::rules in app/Config/bootstrap.php file,
but it doesn't work and I still have the following error :
*Error: Table iti_confs for model ItiConf was not found in datasource default.*
Do you please have any idea or hint about this problem and the synthax of the related inflector rule needed ?
Thanks you by advance !

While Cake has its conventions, it doesn't require them to be used. In this case, try the $useTable property to change the table the model uses, instead of modifying Inflector rules:
class ItiConf extends AppModel {
public $useTable = 'ItiConf';
}

I work in cakephp, I have a database table named 'movements' I want the named 'movements_bags' what changes need to be made:
- The model
-the controller
-folder view
To use a table with a name that is outside the CakePHP table naming convention (e.g. Movement model has table names movements, but you want to use the table named movements_bags) you simply specify which table name to use in your model with the $useTable property:
class Movement extends AppModel {
var $useTable = 'movements_bags'; // default would be movements
// ...
}
I prefer Scrowler answer, but if you are not happy with this answer you can try bellow code.
change controller name to MovementsBagsController.
And change controller class name
class MovementsBagsController extends AppController {
}
Change your model name to MovementsBag
and change model class name
class MovementsBag extends AppModel {
}
change view folder to MovementsBags
I think that will work fine now.
I am using CakePHP 2.x
There are several database tables setup :
1) Fruit
2) Vege
3) Drink
I am able to access these database tables in a CONTROLLER using this line below. With this line, I am able to access these other tables.
public $uses = array('Get', 'Fruit', 'Vege', 'Drink');
My problem is when trying to access them in a MODEL. When I try this code below, an error occurs.
App::uses('AppModel', 'Model');
class Get extends AppModel {
public function getHistory( $limit ) {
$searchLimit = $limit;
$raw = $this->Fruit->find('all')
An error occurs at the line '$this->Fruit'.
Call to a member function find() on a non-object...
Any ideas how to call multiple database tables in a single MODEL ?
As accessing all the database tables work perfectly in the CONTROLLER, I did this in the CONTROLLER instead of the MODEL. It seems much easier and straight forward to do this in CONTROLLER.
A private function is created in the CONTROLLER, and accessed by other functions using '$this->myPrivateFunctionName()'
First you should read on model associations Model associations
Second, if that doesn't fit your needs (meaning there is no clear association between models, honestly I don't see connection between Get and Fruit) you can use ClassRegistry:
$Fruit = ClassRegistry::init('Fruit');
Before you can use ClassRegistry you must add this before class definition:
App::uses('ClassRegistry', 'Utility');
Associate model by $belongsTo, $hasMany or what ever relation you want.
than access by $this->Fruit->find()
Is there a way in CakePHP 1.3 to define a model association without having a model for the associated table? For example:
<?php
class SomeModel extends AppModel
{
var $useTable = 'some_table';
var $belongsTo = array(
'AnotherModel' => array(
// association data here
)
);
}
?>
Where AnotherModel doesn't actually have a model file. I just want to define the table that model would use and the association details. Is this possible?
Quick answer is: It should be fine. Have you tried it? Worse case scenario is it won't work without the file, so just add the model file. It takes all of two seconds:
<?php
class AnotherModel extends AppModel {
var $name = 'AnotherModel';
}
?>
Done!
UPDATE
If you follow cake convention on the naming of tables, you should be able to reference the table using the appropriate name without the model file. For example:
my_models = MyModel
your_models = YourModel
model_tables = TableModel
However, if you have a table that does not follow convention, you must create a model file that defines $useTable to indicate which table it relates to:
some_table = model file: SomeTable where $useTable = 'some_table';
another_model = model file: CustomModel where $userTable = 'anotherModel';
There is no other way around it. CakePHP is not magic. It needs to know what table is being referenced. Unless you are doing joins. Then in the join you can reference the table.
Today I've got a problem when I tried using following code to alter the model attribute in the controller
function userlist($trigger = 1)
{
if($trigger == 1)
{
$this->User->useTable = 'betausers'; //'betausers' is completely the same structure as table 'users'
}
$users = $this->User->find('all');
debug($users);
}
And the model file is
class User extends AppModel
{
var $name = "User";
//var $useTable = 'betausers';
function beforeFind() //only for debug
{
debug($this->useTable);
}
}
The debug message in the model showed the userTable attribute had been changed to betausers.And It was supposed to show all records in table betausers.However,I still got the data in the users,which quite confused me.And I hope someone can show me some directions to solve this problem.

Model::useTable is only consulted during model instantiation (see the API documentation for Model::__construct). If you want to change the model's table on the fly, you should use Model::setSource:
if ( $trigger == 1 ) {
$this->User->setSource('betausers');
}
The table to use is "fixed" when the model is loaded/instantiated. At that time a DB connection object is created, the table schema is being checked and a lot of other things happen. You can change that variable later all you want, Cake is not looking at it anymore after that point.
One model should be associated with one table, and that association shouldn't change during runtime. You'll need to make another model BetaUser and dynamically change the model you're using. Or rethink your database schema, a simple flag to distinguish beta users from regular users within the users table may be better than a whole new table.
