Cannot generate model in Yii framework using Gii, warning: count(): Parameter must be an array or an object that implements Countable

Question

Whenever I try to generate a model using Gii in the Yii framework, it throws:

php warning : count(): Parameter must be an array or an object that implements Countable

It also mentions following file:

app\protected\vendor\yiisoft\yii\framework\gii\generators\model\ModelCode.php(371)

While questions with same title exists, none of them fixed mine.I'm using yii version 1.1.14 and windows 10

Answer 1

You should upgrade Yii to 1.1.21 - this bug was fixed almost 2 years ago.

Answer 2

If you want to fix it without upgrading your existing Yii version, then follow as below. Go to

framework/gii/generators/model/ModelCode.php:371

and fix with

$pk=$table->primaryKey;
$count=is_array($pk) ? count($pk) : 1;
return ($count === 2 // we want 2 columns

Just check the $pk is an array or not and store value in a new variable $count and return it.

Answer 3

Downgrading Php to 5.6 works fine with the older versions of yii.
