DataObject validation for duplicate record
14 January 2013 at 3:30pm
Hi,
I would like to check if a certain record already exist before adding it in the table. Show meaningful error message
to the user too if it failes. I am using DataObject and ModelAdmin to manage those tables.class Country extends DataObject {
static $db = array('CountryName');
....
//check if country exist before saving
....
}
Is there anyone who would like to share some idea how to accomplish this?
Thanks!

The netefxvalidator works well with modeladmin, for ss 2.4 and 3.0
The unique rule is what you are looking for.You have to add the validator in a function getCMSValidator
Download: https://github.com/lx-berlin/NetefxValidator

Hello lx,
Can you share your thoughts on vlaidation on CMS (backend) please.Assuming I have a Product DataObject, containing name, price and date fields,
how can I validate these fields while I'm adding a new product at the backend.A piece of sample code for validator function would be very helpful.
Thank you very much -

Hi soolan,
here are some example rules, that are a little bit more complex than just "required".
I hope they are working.regards
lxclass Product extends DataObject {
...
public function getCMSValidator() {
$rule_Name_required = new NetefxValidatorRuleREQUIRED ("Name", "The name of the product is required.");
$rule_Price_higher_zero = new NetefxValidatorRuleGREATER ("Price", "You need to enter a price higher than 0.", null, "0");
$rule_Date_required = new NetefxValidatorRuleREQUIRED ("Date", "The date is required.");
$rule_Date_in_future = NetefxValidatorRuleFUNCTION("Date", "The date has to be in the future.", null,array('NetefxValidatorLibraryDate', 'DateIsMinDaysAfterToday', array('date' => 'Date', 'min' => 1)));$validator = new NetefxValidator($rule_Name_required, $rule_Price_higher_zero, $rule_Date_in_future, $rule_Date_required);
return $validator;
}...
}
