Question

How would one do something like:

  = f.input_field :age,
                  :collection => 18..60,
                  :id => 'age',
                  :selected => params[:age].blank? or "20"

Above doesen’t work. I want to be able to set a default value if there is no param available for that attribute.

Any smart way to do this thx!

EDIT 1:
Full form:

  = simple_form_for  :people,  :url => request.fullpath, :method => :get,  :html => { :class => 'form-search' } do |f|
    #container_search_small.form-search


      = f.input_field :age,
                      :collection => 18..60,
                      :id => 'age',
                      :selected => params[:people][:age_from] || "20"



      = f.submit "Go »"

Answer 1

You’re using helpers that are taking their values from the object you’re building the form on.

So in your controller, you should preset the values on the object.

def some_action
  @people = People.new
  @people.age = params[:age] || 20
end

Then in the form, remove the :selected option and it should be fine. Make sure you build the form for @people :

= simple_form_for  @people,  :url => request.fullpath, :method => :get,  :html => { :class => 'form-search' } do |f|
  #container_search_small.form-search


    = f.input_field :age,
                  :collection => 18..60,
                  :id => 'age'



    = f.submit "Go »"
