has no attribute named " ".

Error message

{class} has no attribute named "{name}".

What it means

setAttribute() writes into the model's attribute store only after hasAttribute() confirms the name — meaning it is either already present in _attributes or is a column of the model's table schema. Any other name raises InvalidArgumentException with the class and the offending attribute, stopping typos and writes to columns the schema does not know.

Solutions

1. Fix the attribute name to exactly match the table column
2. Flush the schema cache after altering the table (Yii::$app->cache->flush(), or disable enableSchemaCache in dev)
3. For virtual properties, add a setter (setXyz) instead of using setAttribute
4. Guard writes: if ($model->hasAttribute($name)) { $model->setAttribute($name, $value); }

Example fix

// before
$user->setAttribute('emial', 'a@b.c'); // throws: has no attribute "emial"

// after
$user->setAttribute('email', 'a@b.c');

if (!$model->hasAttribute($name)) {
    throw new InvalidArgumentException(get_class($model) . " has no attribute '{$name}'.");
}
$model->setAttribute($name, $value);

When it happens

Trigger: $model->setAttribute('emial', $v) with a typo; setting a column added to the table after the schema cache was populated; setting a virtual/computed property that exists only as a getter; mass-assignment loops that feed unvalidated keys.

Common situations: Stale schema cache after ALTER TABLE in development; form or importer data containing extra keys; column renamed in migration but code not updated; copy-pasting attribute names across similar models.
