Can someone explain to me why I'm getting undefined method when I add day[] (an array) to my select tag
<%= form_for [@hourable, @hour] do |f| %>
<%= f.select 'day[]', options_for_select(days_hours) %>
<% end %>
But when I have it like this :day:
<%= form_for [@hourable, @hour] do |f| %>
<%= f.select :day, options_for_select(days_hours) %>
<% end %>
It works fine?
Thanks
In f.select helper, the first argument is the property you want to assign. There is no property day[]. What you need here is :multiple => true option. So, it will look like:
f.select(:day, options_for_select(days_hours), {}, :multiple => true)
For more information, see the docs
:multiple => true allows to select multiple items in one select field right? So what if I want separate the select fields, say two different select fields but same name, would I have to just change f.select to select_tag? Thanks
You can also use select_tag helper:
<%= select_tag "days[]", options_for_select(days_hours), {:multiple => :multiple} %>
It's only another option. Roman's answer give you what you wanted.
Hope it helps :)
