laravel 4验证器错误数组到字符串转换

Question

大家好，我有一个验证器错误，我找不到解决方案。 我有以下验证规则：

'meta_description'     => 'required|max:200',
'meta_keywords'        => 'required|max:200',
'item_url'             => 'required|max:500',
'categories'           => 'required|not_in:0',
'tags'                 => 'required|not_in:0',
'title'                => 'required|max:150',
'description'          => 'required|max:500',
'author-name'          => 'required|max:250',
'author-link'          => 'required|max:250',
'format'               => 'required|max:300',
'smart-objects'        => 'required|max:300',
'dimensions'           => 'required|max:300',
'photoshop-version'    => 'required|max:300',
'file-size'            => 'max:300',
'link'                 => 'max:500',
'main_item_image'      =>'required|mimes:jpeg,bmp,png,jpg|max:10000',
'item_image'           => 'required|mimes:jpeg,bmp,png,jpg|max:10000',

验证有效，但是当所有输入都填满并且我尝试提交时，我收到以下错误：数组到字符串转换“，文件”：“\path to laravel project/vendor/laravel/framework/src/Illuminate/Validation /Validator.php","line":858.

我刚刚发现问题标签验证包含多个 id 并且 not_in:0 是问题。
