ruby on rails - Why do I have to add .to_i for Postgresql to know this field is an integer? -

The following line works fine in MySQL, but in Postgresql I get a rail error, "Fixnum does not convert to string Can be done ".

  viewable.update_editrile (: total_views, viewable.Tot_views.to_i + 1)  

Total_view is an integer field

The short answer is "yes" the rail should know how to make that column as an integer Deserialize

  viewable.increment (  
  
: total_view))
