sample data output to template page from simple model

$content = $mv -> pages -> defineCurrentPage($mv -> router);
 echo $content -> name;
echo $content -> title;
echo $content -> content;

there is a $content object with data for the current page. It has $content -> id is the id of this page from the pages table.
The pages_blocks table contains rows with links of pages and blocks by their id. It is necessary to extract from there all the lines with pages_id = $content -> id. And then from these lines take blocks_id which will be the blocks for the page.
