laravel column updated_at of relation does not exist code example

Example 1: Column not found: 1054 Unknown column 'updated_at'

// turn off both 
public $timestamps = false;

// turn off only updated_at
const UPDATED_AT = false;

Example 2: Unknown column '.updated_at'

In the model, write the below code;
public $timestamps = false;

Explanation : By default laravel will expect created_at & updated_at column 
in your table. By making it to false it will override the default setting.
