puts converts ruby object into string by invoking to_s method on object. The default to_s prints the object’s class and an encoding of the object id. In order to print human readable form of object use inspect<div class='code-highlight'><pre class='code-highlight-pre'><div data-line='1' class='code-highlight-row numbered'><div class='code-highlight-line'>locs = Location . find_by_sql ( 'select * from locations' )
</div></div><div data-line='2' class='code-highlight-row numbered'><div class='code-highlight-line'>Location Load ( 0 . 5 ms ) select * from locations </div></div></pre></div>
