Using :collection and :include_blank in Formtastic. How to do it?
formtastic, ruby-on-rails
Solution
What kind of association is `:organizations`? Does it work if you specify `:as => :select`?
There's spec coverage for the following `belongs_to` select, date, time and datetime inputs:
f.input(:author, :as => :select, :include_blank => true)
f.input(:created_at, :as => :date, :include_blank => true)
f.input(:created_at, :as => :time, :include_blank => true)
f.input(:created_at, :as => :datetime, :include_blank => true)
My guess is that organizations is not a `belongs_to` association, right? If it's a `:has_many` or `:has_and_belongs_to_many` association, Formtastic will try to do checkboxes or a multi-select. In the case of a multi-select, obviously it makes no sense to have a blank line in there (you just don't select any of the items).
Hope this helps, please post some more details about the models and associations in question.
Problem
I use the superb Formtastic plugin for Ruby on Rails. Does anybody know how to include a blank (option), when using a custom collection? When I try: ``` <%= f.input :organizations, :collection => Organization.all(:order => :name), :include_blank => true %> ``` I get the select box with the collection, but NOT a blank...
