CakePHP : Translate Behaviour : Fixing Nested Translation Problem

If you ever tried to use Translation Behaviour of CakePHP you should realize that Translate Behavior does not support nested translations for the model relations. I’ve found one article that shows how to fix a similar translation problem on related models at

Unfortunately it was not a complete solution that you can implement easily but it gave me a good approach to help the model to request nested queries to make Translate Behaviour work.

I need to warn you that this solution is not a really good one but until CakePHP team fix this issue on one of the future releases of CakePHP this would help you a lot.

Here is the code:

class AppModel extends Model {

    var $_findMethods = array('all' => true, 'first' => true, 'count' => true,
		'neighbors' => true, 'list' => true, 'threaded' => true, 'translated' => true);

    function _findTranslated($state, $query, $results = array()) {
        if ($state == 'before') {
            return array_merge($query, array(
                //'fields' => array('id', 'name'),
                //'recursive' => -1
        } elseif ($state == 'after') {
            if (empty($results)) {
                return $results;

            // get the model's belongs to relation model names
            $belongsTo = Set::extract($this->belongsTo, '/@*');

            if(!empty($belongsTo) && isset($belongsTo[0]) && is_array($belongsTo[0]))
                $belongsTo = $belongsTo[0];

                foreach($results as &$result)
                    foreach($belongsTo as $modelName)
                        if(isset($result[$modelName]) &&
                            isset($result[$modelName]['id']) &&

                            $data = $this->$modelName->find('first', array(
                                'conditions' => array(
                                    $modelName.'.id' => $result[$modelName]['id']
                                'recursive' => -1

                                $result[$modelName] = $data[$modelName];

            return $results;

What you need to do is just implement the _findTranslated method on your model or on AppModel for general usage with the $_findMethods private variable and instead of using regular find methods for example:


You should use:


And the result will look as the same above but with translated inner relations.

Not: I have not implement all types of the relations yet but if you find hard to add such relations let me know, I’ll do my best.

I hope this could help you. Please leave me some responses to make sure is helpful.

Thank you for reading this article.

Ext JS Templates – The Complete Tutorial

Today I’ve searched all over the web sites to find some basic Ext JS template definitions and could not find a good resource as I needed. So, I decided to bring out one myself. Hope you will enjoy.


Ext JS templates have their own parsing algorithms that needs to be compiled before used and here is a quick start to it.

Defining Variables

If you would like to add variables on the template you need to surround the variable name with curly parentheses (‘{‘ and ‘}’ ).



Using Variables in Texts

To add variables into the predefined texts you can just add the variable with curly parentheses where you want to put the variable.


This page has {page_picture_count} pictures.

Using HTML Tags on Templates

It is the same way you add html tags on your Ex JS template as adding predefined text.


<a id="{id}" href="{url}">{text}</a>


You can set conditions to perform on template rendering to the parameter as well. How you do this is pretty simple.


<tpl if="your condition">{field}</tpl>

Example 1 (If condition):

<tpl if="{field}=='Good Example'">{field}</tpl>

With this template what ever else the field variable is will not be evaluated except if it is equal to ‘Good Example’ string.


You can use loops when you need to output a list of variables.


<tpl for="{parent}">{child}, </tpl>

With this template for each child in parent will be separated with columns.

Example 2 (If and Else If condition):

<tpl if="{field}=='Good Example'">{field}</tpl>
<tpl if="{field}=='Else Example'">{field}</tpl>

With this template what ever else the field variable is will not be evaluated except if it is equal to ‘Good Example’ or ‘Else Example’ string.

Using Predefined Functions on Templates

Ext JS has internal Template functions that are useful for your templates.

Suppose we want to output a variable named content but we are afraid that it may take too much space. A useful feature would be able to truncate this content to 50 characters and show the user a link to view all of the content. We can use the formatting function “ellipsis” to truncate the content to only 50 characters. This function will also append “…” to indicate to our users that there is actually more content but it has been truncated.


<div>{content:ellipsis(50)}<br/><a href="{moreLink}">Read More</a></div>

Here is a list of the formatting functions which you can use with Templates:

ellipsis(length): Abbreviate your variable to a specified length and append “…”. Useful for when you want to only show the first x characters and then provide a more detailed view.

undef: If the variable is undefined show “” instead of “undefined”

htmlEncode: If the variable contains ampersands, less than, greater than symbols or quotes HTML escape them.

trim: If the variable contains extra rwhite space, trim it.

substr(start, length): Substring the variable

lowercase: Transform the variable to all lowercase.

uppercase: Transform the variable to all uppercase.

capitalize: Capitalize the first letter of the variable, the remaining characters will be transformed to lowercase.

usMoney: Format in US Dollars. ie: $10.97

date[(format)]: Transform the variable to a date format, if the format argument is omitted uses the mask ‘m/d/Y’

stripTags: Strips the variable of all html tags.

You can also create your own custom formatting functions by adding a new method to your template instance and calling it by prepending this. to your format function like this “{VARIABLE:this.<FORMATFUNCTION>}”

Here is a sample which adds a new function called yesNoFormat to an instance of a template. yesNoFormat is similar to a ColdFusion function which converts ‘truthy’ values to the word “Yes” and ‘falsey’ values to the word “No”.

var testCustomTpl = new Ext.Template(
    '<div>User: {username} IsRevoked: {revoked:this.yesNoFormat}</div>'
testCustomTpl.yesNoFormat = function(value) {
	return value ? 'Yes' : 'No';
testCustomTpl.append(document.body, {username: 'aconran', revoked: 1});

Note: This post will continue when I found something else and developing some examples on Ext JS Templates.

What Happend With Migration Process?

I was trying to migrate from Ext JS 3 to Ext JS 4 and could not manage to fix all the problems that occurred with the developed Ext JS 3 project of mine. Then I tried to figure out if I could build a complete application from beginning and if there is any easy way to do that. Finally I decided not to start anything about migration at this point of the project when I do not really need it because it will take too much time to finish the project of which I don’t have.

Later I’ll do the migration with another project I suppose.

Migrating from Ext JS 3.0 to Ext JS 4.0

Today I feel very lucky and I decided to migrate all my application that I build on the Advertisement Agenda project and may be I can find some easy ways of migration. This is the first time I intend to migrate any older version of a framework in the middle of a project. Let’s see what is waiting for e :) .

By the way, there is a complete tutorial and an easy way of doing the migration with a compatibility tool that you should install. But I want to have complete new start with Ext JS 4. And why I need to migrate is the API that I use is not compatible with the application I’m developing. It is really become a confusion for me.  Here I go..

Step By Step Migration Plan

  1. Backup Project Files for later needs
  2. Download new release of Ext JS from
  3. Just change the base ext file path to the new one.
  4. Try it out.
  5. If there has been a problem, try to figure out what is it and solve the problem.
  6. Continue to the 4th step until there is no problem.
  7. If I still came up nowhere, start to build a complete new application.

So, how did it go? I did the first 4 steps and jump to the 7th one :D . It looks like I need a complete new application.

Here what it is! There is not enough documentation about the steps to build an application from start. I decided watch those videos first:

I must say, I’m stucked! I’ll go through examples, that will do.

New Ext JS 4.0 API Documentation

Ext JS 4.0 API

After Sencha own  Ext JS, they have started to build a new corporation face from beginning and recently the realized new version of Ext JS with customizable templates. I wanted to post this review to share new API link at Ext JS API. For me it is really slow and there are many links that are actually old version API and not working properly. I’ll keep waiting for the changes on the documentation and love it anyway to figure out more “how to do”s on it.

Find out new API at
