Create custom methods to check before find

[Davide Pastore]

There is some way to create custom methods to check the values before call find_ methods?

An easy example:

<?php

class User extends Model{
    public static $_table = "User";
    public static $_id_column = "UserID";

    /**
     * Check if the user can login.
     * @return true if the user can login, false otherwise.
     */
    public function canLogin($username, $password){
        return $this
            ->where('Username', $username)
            ->where('Password', $password)
            ->count() > 0
    }
}

and then call it using:

<?php

$username = 'foo';
$password = 'foosecret';

if(Model::factory('User')->canLogin($username, $password)){
    echo('You can login.');
}
else{
    echo('You can\'t login.');
}

I am not sure I understand what you're asking for, but I would suggest the pattern that I use in these situations:

class User extends Model {
    public static $_table = "User";
    public static $_id_column = "UserID";

    /**
     * Check if the user can login.
     * @return true if the user can login, false otherwise.
     */
    public static function canLogin($username, $password) {
        return Model::factory(__CLASS__)
            ->where('Username', $username)
            ->where('Password', $password)
            ->count() > 0;
    }
}

$username = 'foo';
$password = 'foosecret';

if(User::canLogin($username, $password)) {
    echo('You can login.');
} else{
    echo('You can\'t login.');
}

If you're talking about validating the actual values passed into a model then you should see https://github.com/tag/sudzy

Your example it's exactly what i was looking for. Thanks @treffynnon. I think that can be useful for other users. Why don't add it in the documentation?
