Re: displaying 2 tables

Hey that looks correct to me, I probably should have been more specific over recursive.

By default recursive is switched on, which means when you query a specific model, it will find associated tables along with it (up to 1 level I believe), you can change recursive to find more associated tables or none at all. I find it best practice to turn this off immediately as I like to specify which models and fields should be queried to be more efficient.


I do this by adding public $recursive = -1; in my AppModel.php file.

This brings us to contain which is what you should use when you want to find associated tables in your query (if recursive isn't switched off you may not need to do this), I forgot to mention you'll likely need to enable this behaviour (I do this in AppModel).

Hi,

OK you need to be a bit more specific as I am new to this.

Say I have 2 tables table1 and table2 and each has its own model.
table1 has a 1 to many relationship with table2.

table1 has a id
table2 has the same id as a foreign key.


In my table1 model

public $belongsTo = array('Table2');

In my table2 model

public $hasMany = array('Table1');


The query
$everything = $this->Table1->find('all', array('contain' => array('Table2')));
// Assuming recursive is -1 in your AppModel ??????????????? where is this please

Then I can access the data from a view

foreach($everything as $data) {
    echo $user['Table1']['name'];
    echo $user['Table2'']['username'];
}

Is this correct?

Hey

Name refers to the name of the model, you may also be interested in $useTable = 'table_name' to specify a table name other than the plural of your model name.

As for referring to two database tables in one view, you don't necessarily need to have two controllers for this but you should have two models. Let assume you have a User model and a UserType model (Where the users table has a field named user_type_id)

In your users model



public $belongsTo = array('UserType');

In your user type model

public $hasMany = array('User');

The query$users = $this->User->find('all', array('contain' => array('UserType'))); // Assuming recursive is -1 in your AppModel


Then you can access to the UserType like such

foreach($users as $user) {
    echo $user['UserType']['name'];
    echo $user['User']['username'];
}

Hi,
I have just started cakephp and got working an example.

if you look at a hello world example from cakephp then I have these files.
I have a table name called users and looking at the blog tutorial that name users should refer to a database name .

q1)My example works but what is correct? Is the name 'users' a table or databasename?

q2)How do I refer to 2 database tables in the 1 view as do I need another model and controller for every database table I access?

http://book.cakephp.org/2.0/en/tutorials-and-examples/blog/part-two.html

<?php
class User extends AppModel
{
var $name='User';
}
?>

<?php
class UsersController extends AppController
{
var $name='Users';
function index()
{
}
}
?>

<html>

<?php

/*http://127.0.0.1/cakephp/users/    */
echo "Hello World";
?>
</html>
