Yii Framework Churn data type

Yii Framework Change data type
The previous database has a field that is numeric, and I use the Yii tool GII to generate it, model,conttroler,view, and other layers. Later, because of the requirements, to change the value to a string, so I will change the value of the database type (char type). Then put the model layer of the Rules () method under the array: Array (' Aa,bb, ', ' numerical '),

Switch

Array (' AA,BB ', ' length ', ' Max ' =>20),

When I finally entered the character extraction data, the following error occurred:

CDBException
The column name must be a string or an array

D:\web_root\rd1039b\framework\db\schema\CDbCommandBuilder.php (701)

689}
690 if (count ($values) ===1)
691 {
692 $entries =array ();
693 foreach ($values [0] as $name = $value)
694 $entries []= $prefix. $table->columns[$name]->rawname. ($value ===null? ' Is NULL ': ' = '. $value);
695 return implode (' and ', $entries);
696}
697
698 return $this->createcompositeincondition ($table, $values, $prefix);
699}
-Else
701 throw New CDBException (Yii::t (' Yii ', ' Column name must is either a string or an array. '));
702}

252 if (Yii::app ()->user->role==study_user_role_pi) {
253 $model->entry2who= Yii::app ()->user->username;
254 if ($model, Save ())
255 {
if ($SORT!=3) {
257 $this->todo ($Name, $MH 1, $keyid);
258}
259 Else

Excuse me master, what is this reason? Please help, thank you Ah!!

------Solution--------------------
690 if (count ($values) ===1) Here $values is the array (' AA,BB ', ' length ', ' Max ' =>20), right? If yes, then count ($values) ===1 is False

Unable to verify the specific error.

You can remove the rules (). Try it, could you. If you can use it, the instructions are a problem with your rules () method. If it doesn't work, it means it's wrong to write somewhere else.

Simple example of rules rule
Public Function Rules ()
{
Return Array (
Array (' name,email ', ' length ', ' Max ' =>6),
);
}

This is a list of specific rules
