CakePHP - how to apply translate behavior to existing database? - database

Question

I have and existing application in CakePHP with a database.
The task is to apply translate behavior to its models. The problem is that i18n.php script just creates _i18n table but doesn't copy existing data to this table.
Don't you know any script that could do that?
Thanks for any help.

Answer 1

I extended the answers from Aziz and MarcoB and created a even more generic CakeShell out of it.
In the method _execute() simply set something like:
$this->_regenerateI18n('BlogPosts', array('title'), 'deu');
And all entries for the Model BlogPosts for the column title in the language deu will be create in the i18n table.
This is CakePHP 2.4 compatible!
<?php
class SetuptranslationsShell extends AppShell {
public function main() {
$selection = $this->in('Start to create translated entries?', array('y', 'n', 'q'), 'y');
if (strtolower($selection) === 'y') {
$this->out('Creating entries in i18n table...');
$this->_execute();
}
}
function _execute() {
$this->_regenerateI18n('BlogPosts', array('title'), 'deu');
$this->_regenerateI18n('BlogTags', array('name'), 'deu');
}
/**
* See http://stackoverflow.com/q/2024407/22470
*
*/
function _regenerateI18n($Model, $fields = array(), $targetLocale) {
$this->out('Create entries for "'.$Model.'":');
if (!isset($this->$Model)) {
$this->{$Model} = ClassRegistry::init($Model);
}
$this->{$Model}->Behaviors->disable('Translate');
$out = $this->{$Model}->find('all', array(
'recursive' => -1,
'order' => $this->{$Model}->primaryKey,
'fields' => array_merge(array($this->{$Model}->primaryKey), $fields))
);
$this->I18nModel = ClassRegistry::init('I18nModel');
$t = 0;
foreach ($out as $v) {
foreach ($fields as $field) {
$data = array(
'locale' => $targetLocale,
'model' => $this->{$Model}->name,
'foreign_key' => $v[$Model][$this->{$Model}->primaryKey],
'field' => $field,
'content' => $v[$Model][$field],
);
$check_data = $data;
unset($check_data['content']);
if (!$this->I18nModel->find('first', array('conditions' => $check_data))) {
if ($this->I18nModel->create($data) AND $this->I18nModel->save($data)) {
echo '.';
$t++;
}
}
}
}
$this->out($t." entries written");
}
}

As far as I know, there's no way to do this. Moreover, because of the way the i18n table is configured to work, I think there's a better solution. A while back, I wrote a patch for the TranslateBehavior that will keep you from having to copy existing data into the i18n table (that felt insanely redundant to me and was a huge barrier to implementing i18n). If no record for that model exists in the i18n table, it will simply read the model record itself as a fallback.
Unfortunately, the Cake team appears to have moved everything to new systems, so I can no longer find either the ticket or the patch that I submitted. My patched copy of the TranslateBehavior is in my Codaset repository at http://codaset.com/robwilkerson/scratchpad/source/master/blob/cakephp/behaviors/translatable.php.
As you might expect, all of the usual warnings apply. The patched file was developed for 1.2.x and works for my needs, by YMMV.

try to use it
function regenerate()
{
$this->Article->Behaviors->disable('Translate');
$out = $this->Article->find('all', array('recursive'=>-1, 'order'=>'id'));
$t = $b = 0;
foreach($out as $v){
$title['locale'] = 'aze';
$title['model'] = 'Article';
$title['foreign_key'] = $v['Article']['id'];
$title['field'] = 'title';
$title['content'] = $v['Article']['title'];
if($this->Article->I18n->create($title) && $this->Article->I18n->save($title)){
$t++;
}
$body['locale'] = 'aze';
$body['model'] = 'Article';
$body['foreign_key'] = $v['Article']['id'];
$body['field'] = 'body';
$body['content'] = $v['Article']['body'];
if($this->Article->I18n->create($body) && $this->Article->I18n->save($body)){
$b++;
}
}
}

Thanks Aziz. I modified your code to use it within the cakeshell
(CakePHP 2.3.8)
function execute() {
$this->out('CORE_PATH: '. CORE_PATH. "\n");
$this->out('CAKEPHP_SHELL: '. CAKEPHP_SHELL. "\n");
$this->out('Migrate BlogPosts');
$this->regenerateI18n('BlogPost', 'title', 'BlogPostI18n');
}
/**
* #param string $Model
* #param string $Field
* #param string $ModelI18n
*/
function regenerateI18n($Model = null, $Field = null, $ModelI18n = null)
{
if(!isset($this->$Model))
$this->$Model = ClassRegistry::init($Model);
if(!isset($this->$ModelI18n))
$this->$ModelI18n = ClassRegistry::init($ModelI18n);
$this->$Model->Behaviors->disable('Translate');
$out = $this->$Model->find('all', array('recursive'=>-1, 'order'=>'id'));
$t = 0;
foreach($out as $v){
$data = array(
'locale' => 'deu',
'model' => $this->$Model->name,
'foreign_key' => $v[$Model]['id'],
'field' => $Field,
'content' => $v[$Model][$Field],
);
if($this->$ModelI18n->create($data) && $this->$ModelI18n->save($data)){
echo '.';
$t++;
}
}
$this->out($t." Entries written");
}
