Question

I have the following view code:
<%= f.select :day_of_play, Team::DAYS_OF_WEEK %>

And I have to create the following map for it to work and display a select box:

DAYS_OF_WEEK = {"Sunday" => 0,
                  "Monday"=>  1,
                  "Tuesday"=> 2,
                  "Wednesday"=>3,
                  "Thursday"=>4,
                  "Friday"=>  5,
                  "Saturday"=>6,
  }

I store the integer in the database, but then when I display the integer it seems backwards that I have to create another map in order to go from integer->to->Saturday?

What am I doing wrong and how should I implement this correctly, soit is the dry principle?

Answer 1

If you want to adhere to the DRY principle, I recommend using Date::DAYNAMES.

E.g. like this:

<%= f.select :day_of_play, Date::DAYNAMES.each_with_index.collect { |day,i| [day,i] } %>
