has_one relations. Get title from ID in the template
1 November 2007 at 1:58pm
Hi,
i just started to play around SS. I have a little problem which, i guess, can be easy solved.
I install countries, which i can chose in the admin system, but i can't get this country name in the templates, because i got just it ID from variable $CountryID.
Any ideas how to declarate country title from it ID.
class Lake extends Lakes {
static $db = array(
'CountryID' => 'Int'
);
static $has_one = array(
'Countries' => 'Country'
);function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab('Root.Content.Country',new DropdownField('CountryID','Select one',DataObject::get('Country')->toDropDownMap('ID', 'Title')));
return $fields;
}}
Thank you,
Vitas -

If I understand correctly, you can put something like this in your LakeController class:
public function Country() {
$country= $this->getComponent('Country');
return $country;
}Then in the template, use $Country.Title to get the country's name.
I think.

You shouldn't need to add 'CountryID' as a $db array entry. The has_one automatically makes a CountryID for you I thought.
I think the way you've named has_one = array('Countries' => 'Country') is confusing, I would've made it 'Country' => 'Country' as it's only one component, and not more than one.
You should just be able to call $Countries in the template, or $this->Countries() in the code on the controller to return your country object (with the current way you've got it setup). Is that not the case?
Hope this helps,
Cheers,

Thank You Sean for your advice.
Looks i solved the problem for now, but I guess that this way is not correct. I think the problem still exist because I was not able to use any suggested code in this forum.
I will be interesting to know other ways how to solve this problem. Please, let me know.
Currently working code:
<?php
class Lake extends Lakes {
static $db = array(
);
static $has_one = array(
'Countries' => 'Country'
);function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab('Root.Content.Country',new DropdownField('CountryID','Select one',DataObject::get('Country')->toDropDownMap('ID', 'Title')));
return $fields;
}}
class Lake_Controller extends Lakes_Controller {
public function Country() {
$country = DataObject::get_one("Country", "`Country_Live`.ID = ".$this->__get('CountryID'));
return ($country)?$country->__get('Title'):false;
}}
?>
This code should not be like i described in the controller, but i think that here still is bug. I found one link, where was described problem about dropdown then CMS do not save selections. I guess this kind of code is temporary.
