i am newbie in cakephp and trying to implement this query
SELECT DISTINCT textmessage.mobileNo FROM textmessage
JOIN contacts
ON textmessage.User_id=contacts.User_id AND textmessage.mobileNo = Contacts.mobileNo
i am expecting only one result here .. want to implement this query in textMessage Controller ... i have never use join query before in CAKEPHP... i have actually a mobileNo field in both the tables and i want to retrieve the mobileNo if the mobileNo of textmessage table is also in Contacts table
here is what i have modified your query according to my requirments ..
$this->bindModel(array('belongsTo' => array('Contact' => array('className' => 'Contact',
'foreignKey' => false,
'conditions' => array('Message.user_id = Contact.user_id','Message.mobileNo = Contact.mobileNo')))), true);
return $message_details = $this->find('all', array('conditions' => array(),
'fields' => array('DISTINCT mobileNo')));
Put the following code in your controller's code:
If you need only single record:
function test1()
{
$this->TextMessage->bindModel(array('belongsTo' => array('Contact' => array('className' => 'Contact',
'foreignKey' => false,
'conditions' => array('TextMessage.user_id = Contact.user_id')))), false);
$message_details = $this->TextMessage->find('all', array('conditions' => array(),
'fields' => array('DISTINCT mobileNo')));
}
If you have multiple text messages corresponding to each contact then try the following:
function test2()
{
$this->Contact->bindModel(array('hasMany' => array('TextMessage' => array('className' => 'TextMessage',
'foreignKey' => false,
'conditions' => array('TextMessage.user_id = Contact.user_id'),
'fields' => array('DISTINCT mobileNo')))
), false);
$message_details = $this->Contact->find('all', array('conditions' => array()));
}
You can also write the association in your model. I gave you an example to dynamically join any table on the fly.
According to your edited question, if you don't need two arrays. Use query() function.
Hope this will fulfill your requirement.

I would like to add a "virtual" field to a Prestashop 1.6 custom table in the back office. The field indice_calculo_pvp2 should not be saved into the database, as it is a calculated from the values of indice_calculo_pvp and precio_venta_recomendado. What would be the correct way to implement this?
My code is as follows :
public function renderList() {
$this->addRowAction('edit');
$this->addRowAction('delete');
$this->fields_list = array(
'id_product_price' => array(
'search' => false,
'title' => 'ID'
),
'precio_coste' => array(
'title' => 'Precio coste',
'search' => false,
'callback' => 'callback_format_price',
'suffix' => '€'
),
'indice_calculo_pvp' => array(
'title' => 'Indice de cálculo PVP',
'search' => false,
'callback' => 'callback_format_price',
'suffix' => '%'
),
'indice_calculo_pvp2' => array(
'title' => 'Indice de cálculo PVP2',
'search' => false,
'callback' => 'callback_calculate_pvp',
'suffix' => '%'
),
'precio_venta_recomendado' => array(
'title' => 'Precio de venta recomendado con IVA',
'search' => false,
'callback' => 'callback_format_price',
'suffix' => '€'
)
);
return parent::renderList();
}
Use calculation in your SQL SELECT query for the list. I don't know what your calculation formula and your SELECT query is but example of this:
$this->_select = 'a.indice_calculo_pvp / a.precio_venta_recomendado AS indice_calculo_pvp2';
You have 2 options:
You can use a callback function as in your code:
public function callback_calculate_pvp($id, $tr)
{
return $tr['indice_calculo_pvp'] * $tr['precio_venta_recomendado'];
}
You can use a virtual column in your field list indice_calculo_pvp2 and set the value in your SQL query or in getList override function (as ProductController do with price).
Good luck.

Basically, I have a 1:n relationship where in I need only latest record from child table. The parent table data will be displayed based on the comment that is done latest in child table. How to make this field sortable ?
Error
CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'c.lastactivity' in 'order clause'.
Just a theory:
because you have a join with together sql, all the data will be together in 1 result. I am not sure if you can still use $data->ca->date because your data is not a known active record type.
Try putting
$criteria->select = 'maintable.*,ca.date as ca_date';
then you should be able to use
array(
'header' => 'Last Activity',
'class' => 'gridDataColumn',
'value' => '$data->ca_date',
),
Below is the Model which will allow to have a custom/computational field that will be SORTABLE. Instead of simply writing 'lastactivity'=>'lastactivity' in sort array, passing whole array did the trick for me. Hope it helps someone :)
class Contact extends CActiveRecord {
public $verifyCode;
public $lastactivity;
public static function model($className = __CLASS__) {
return parent::model($className);

public function tableName() {
return '{{contact}}';

);
}

return array(
'ca' => array(self::HAS_MANY, 'ContactAction', 'contact_id'),

$criteria->compare('email', CommonFunctions::escapeOperator($this->email), true, 'OR');
$criteria->compare('status', CommonFunctions::escapeOperator($this->status), true,'OR');
$lastactivity_sql = '(select max(date) from tbl_contact_action ca where ca.contact_id=t.contact_id)';
$criteria->select = array('*', $lastactivity_sql . ' as lastactivity');
$criteria->addCondition('status<>"Deleted"');
$criteria->compare($lastactivity_sql, $this->lastactivity);
$sort = new CSort;
$sort->defaultOrder = array('lastactivity' => CSort::SORT_DESC); //'title ASC';
$sort->attributes = array(
'name' => 'name',
'email' => 'email',

I'm using fuelphp's orm to model my data. How can I control which order my child elements are returned when doing a cascaded find.
For example, here's the example config to attach comments to a post:
protected static $_has_many = array(
'comments' => array(
'key_from' => 'id',
'model_to' => 'Model_Comment',
'key_to' => 'post_id',
'cascade_save' => true,
'cascade_delete' => false,
)
);
How can I say, for example, order the comments by the 'date_entered' field?
Thanks in advance,
David
You can add the order_by clause to the conditions.
protected static $_has_many = array(
'comments' => array(
'key_from' => 'id',
'model_to' => 'Model_Comment',
'key_to' => 'post_id',
'cascade_save' => true,
'cascade_delete' => false,
'conditions' => array(
'order_by' => array(
'field1' => 'DESC',
'field2' => 'ASC',
)
),
),
);
Note that as they are defined in the relation, they are always active and can not be turned off!
What I am trying to do is create a selectlist using the form API, where a user can select rows and press a delete button that deletes the selected rows from the database and reloads the table with a conformation that those selected had been deleted. With my current code, when I hit the delete button I get this error:
Warning: Invalid argument supplied for foreach() in form_execute_handlers() (line 1431 of C:\xampp\htdocs\amaware\includes\form.inc).

Any help is deeply appreciated.
EDIT:
I've edited my news_letter_table_form to read:
function newsletter_table_form_delete ($form, $form_state) {
foreach (($form_state['values']['table']) as $rows) {
//$delete = db_delete('sms_newsletter')
//-> execute();
drupal_set_message ('' . $rows . '');
//drupal_set_message ('' . $form_state['values']['table'] . '');
}
}
And the new output leaves me puzzled as to how I'd identify selected rows, and delete them from the database. Using the above newsletter_table_form_delete I get the following output:
If I select the top row nothing happens
If I select the second row the output is 1
If I select the third row the output is 2 and so on
If I select multiple rows the output is an unordered html list of the selected rows.
I'm curious now how I could take what I have now and change it so I can delete selected rows from the database.
Thanks again!
Try changing
$form['delete'] = array(
'#type' => 'submit',
'#value' => t('Delect Selected'),
'#submit' => 'newsletter_table_form_delete'
);
to
$form['delete'] = array(
'#type' => 'submit',
'#value' => t('Delect Selected'),
'#submit' => array('newsletter_table_form_delete') // <-- make this an array
);
Based on the additional info added in your question edit, I noticed that your tableselect is built without specifying array keys like:
foreach ($results as $line) {
$rows[] = array( // <-- No array keys specified here
$line->name,
$line->number,
$line->email,
);
}
Since there were no keys specified, the default by PHP is a 0-based index. That is why you are getting no results for the top row, 1 for the second row, and so on.
See the documentation for the tableselect element for an example.
I don't know what your database table structure looks like but you will probably need to query the Primary Key for the table and include it as array keys to your $rows array. That way, when you process the data in your delete function, you have the Primary Key of the row you want to delete and delete it.
For me this wasn't clear straight away so.
I would just like to add that in the end what nmc was saying is you should construct your rows like this, where you add a key to row.
foreach ($results as $line) {
$rows[$line->name] = array(
$line->name,
$line->number,
$line->email,
);
I'm trying to use Lithiums list option with find() along with SQL's DISTINCT.
I should get an array populated with values, instead, I'm getting an empty array.
This does make sense since I'm passing in the distinct fields as one string instead of an array of elements but I don't know how else to use DISTINCT in Lithium.
Some direction would be greatly appreciated.
It may be valentines day but Lithium is not showing me too much love today :)
