In my application in user registration I have a country picker..
<%= select(:user, :country, options_for_select(@COUNTRIES)) %>
And I wan
collection_select(:product,
:category_id,
Category.all,
:id,
:title,
{:prompt => true}
)
collection_select(:product,
:category_id,
Category.all,
:id,
:title,
{:include_blank => 'Please Select'}
)
both of these result in the same html, but the first one will not include the 'Please Select' option when you return to edit the previously created Product
Use the FormHelper :prompt
select(:user, :country, options_for_select(@COUNTRIES), {:prompt => "--select county--"})
http://apidock.com/rails/ActionView/Helpers/FormOptionsHelper
Very simple:
select(:user, :country, options_for_select(@COUNTRIES), :prompt=>true)
For the prompt "Please select", or this for your custom text:
select(:user, :country, options_for_select(@COUNTRIES), :prompt=>"Select country")
Also note that @COUNTRIES
is wrong, an instance variable should be lowercase - @countries
, a contant would just be COUNTRIES
.
You can also give customized prompt value like this
select(:user, :country, options_for_select(@COUNTRIES), :prompt=>"select User name")
