$newdata = [ 'title' => 'test', 'body' => 'test body', 'author_name' => 'test', 'author_url' => 'author_url', 'author_email' => 'author_email' ];         $newdata[ 'posts' ] = [ '_ids' => [ 1 ] ];          print_r( $newdata );          $tagentity = $this->posts->comments->newentity();         $tag = $this->posts->comments->patchentity( $tagentity, $newdata );          print_r( $tagentity );         print_r( $tag );          if( $this->posts->comments->save( $tag ) ) {          } 

and result is

array (     [title] => sdsds     [body] => dsfsf     [author_name] => ss     [author_url] => author_url     [author_email] => author_email     [posts] => array         (             [_ids] => array                 (                     [0] => 1                 )          )  ) blog\model\entity\comment object (     [title] => sdsds     [body] => dsfsf     [author_name] => ss     [author_url] => author_url     [author_email] => author_email     [posts] => array         (             [_ids] => array                 (                     [0] => 1                 )          )      [[new]] => 1     [[accessible]] => array         (             [*] => 1         )      [[dirty]] => array         (             [title] => 1             [body] => 1             [author_name] => 1             [author_url] => 1             [author_email] => 1             [posts] => 1         )      [[original]] => array         (         )      [[virtual]] => array         (         )      [[errors]] => array         (         )      [[invalid]] => array         (         )      [[repository]] => blog.comments ) 

finally got working

$data = $this->request->data; $data[ 'posts' ] = ['_ids' => [ $post->id ] ]; $comment = $this->posts->comments->patchentity( $this->posts->comments->newentity(), $data, [ 'posts' ] ); $this->posts->comments->save( $comment );  if( $this->posts->save( $comment ) ) {     echo 'done'; } else {     print_r( $comment ); }
