property model

class property < activerecord::base   attr_accessible  :name, :address_attributes, :tenants_attributes, :meter_attributes,  :council_history, :council_history_attributes, :property_id, :council_id, :status   belongs_to :user     has_one :council_history   accepts_nested_attributes_for :council_history    has_one :council, through: :council_history   accepts_nested_attributes_for :council  end

council model

class council < activerecord::base   attr_accessible :councilemail, :name, :counciltel    has_many   :council_history    has_many   :properties, :through => :council_history  end

council history model

 class councilhistory < activerecord::base   attr_accessible :council_id, :property_id, :vacant     belongs_to :council    belongs_to :property   end

select council view form

<h1>select council</h1>    <%= simple_form_for @property, :url => url_for(:action => 'update', :controller =>   'properties/build'), :method => 'put' |f| %>   <%= f.simple_fields_for :council_history |builder| %>   <%= builder.input :id, :collection => council.all %>   <%= builder.submit %>  <% end %> <% end %>

build property controller

class properties::buildcontroller < applicationcontroller   include wicked::wizard     steps :tenant, :meter, :council, :confirmed     def show     @property = property.find(params[:property_id])     @tenants = @property.tenants.new(params[:tenant_id])     @meter = @property.build_meter     @council = @property.build_council_history     render_wizard   end    def edit     @property = property.find(params[:property_id])   end     def update     @property = property.find(params[:property_id])     params[:property][:status] = step.to_s     params[:property][:status] = 'active' if step == steps.last     @property.update_attributes(params[:property])     render_wizard @property   end end

in property model have attr_accessible :council_history, try removing it.

i didn't test believe problem because have has_one :council_history, simple_fields_for using :council_history instead of generating council_history_attributes parameters.
