entities – Drupal 7 – Get the field value in the module

I need to add to the flow generated by the module, the output of the value of the field after the body $.

I have tried different values ​​of the output options fields in the module, but nothing works.
The model works. But when I insert the code into the module, it does not work or the result is nothing.

I'm trying to win this for a week. I would be very grateful if you told me how to solve it.

Code of the module:

fields ("n", table ("nest," & # 39 ;, & quot ;, & quot;) & quot;) & quot ;,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
-> condition (& # 39; status & # 39 ;, NODE_PUBLISHED)
-> condition (& # 39; type; $ node_types, & # 39; IN & # 39;);

$ query-> leftJoin ("field_data_body", "d.entity_id = n.nid AND d.entity_type =: node"), array (
& # 39 ;: knot & # 39; => & # 39; knot & # 39;
));

$ query-> addField ('body', $ source, & # 39; body & # 39;);

$ query-> leftjoin ('url_alias',' ua ',' ua.source = CONCAT (: str, n.nid) & # 39 ;, array (
& # 39 ;: str & # 39; => & # 39; node / & # 39;
));

$ query-> fields (& # 39; ua; array (& quot; alias & quot;));

if (Yes == variable_get ('yandex_turbo_sticky', 'No'))
{
$ query-> orderBy (& nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;)
}

if (Yes == variable_get (& # 39; yandex_turbo_promoted & # 39; No #);)
{
$ query-> orderBy ('n.promote', 'DESC');
}

$ query-> orderBy (& # 39; n. & # 39 ;. $ orderBy, $ order)
-> range (0, 1000);

$ query-> where (& # 39; d.body _ & # 39;. $ source. # = empty, array (& empty = & & 39; # 39;));

$ feeds = $ query-> execute ()
-> fetchAllAssoc ('nest', PDO :: FETCH_ASSOC);
}

return the theme (yandex_turbo_page_rss, array (& rsquo; feeds & rdquot; => $ feeds));
}
