Rails: helper form helper to run by default

Question

I have a simple form. Also, as part of the form, I have a variable with an array / list of all country names. The form picks up the list just fine, however it starts with the first value, I think its Afghanistan , however I want it to start / default with United Kingdom

This is my code to select a form for countries.

 <%= f.select(:country, @country_list.map { |value| [ value, value ] }) %> 

I tried without success:

 <%= f.select(:country, @country_list.map { |value| [ value, value ] },['United Kingdom']) %> 

Answer 1

Have you tried the selected option

 :selected => "United Kingdom" or your_country_id 

not sure about syntax but hopefully it will work

Answer 2

From the documentation :

Set: selected => to use another choice or: selected => nil to leave all options unselected.

So, if you want the default to be selected, try the following:

 f.select(:country, @country_list.map { |value| [ value, value ] }, selected: "United Kingdom")
