Question

I’ve just started with my first real rails app.

I have a predefined set of salutations (“Herr”, “Frau, “Herr und Frau”) for my customer model.
The app has to deal with an export to a csv file where “Herr” has to be the integer 1, “Frau” 2 and “Herr und Frau” = 3.

Therefore I thought it would be clever to save that salutation as an integer and simply add an salutation_readable method to my customer model like this:

def salutation_readable
    case salutation
    when 1
      "Herr"
    when 2
      "Frau"
    when 3
      "Herr und Frau"
    end
end

to display the salutation in my views.

In the customer form partial I added:

<%= f.select(:salutation, options_for_select([['Herr', 1], ['Frau', 2], ['Herr und Frau', 3]])) %>

Everything works as expected, except the customer edit view where the preselected value is always the first entry and not my saved one.

Answer 1

options_for_select takes a second parameter as the default selected option.

<%= f.select(:salutation, options_for_select([['Herr', 1], ['Frau', 2], 
['Herr und Frau', 3]], @customer.salutation_readable)) %>
