Rails 3 simple form error : couldn't parse YAML

Question

My new.html.erb:

  
New konkurrancer

    <%= simple_form_for [:admin, @konkurrancer] do |f| %
        <%= f.input :name %>
                 


        

Answer 1

You're using a namespaced model - you must reference the namespace in your form path.

Try this:

<%= simple_form_for [:admin, @konkurrancer] do |f| %>

Answer 2

try

<%= simple_form_for ['admin', @konkurrancer] do |f| %>

It looks like you're in a name spaced model?
