ruby on rails - Undefined method "cmdb_searches_path" for form_for in index -

i have cmdbs_controller.rb inside of have index , defined cmdb resource route:

def index    @cisearch = cmdbsearch.new  end

also have cmdb_search model model search form (empty). in index.html.erb want load form_for that:

<%= form_for @cisearch, remote:true  |f| %>  ...some code..             <% end %>

i have done such search other page before, error:

undefined method `cmdb_searches_path'

edit: there no cmdb_search controller, cmdb_model created building search form, used temorarily. example worked: did before , worked:

 #requests_controller.rb  def index    if !user_signed_in?      redirect_to new_user_session_path    else        @requests = request.search(params[:search]).order("#{sort_column} #{sort_direction}").where("payed = ?", false).order(created_at: :desc).paginate(per_page: 20, page: params[:page])       @search = search.new    end  end

have search model. inside requests/index.html.erb have:

<%= form_for @search, remote: true |f| %>    .. code   <% end %>

the way works create search model instance inside requests_controller able create form_for @search. didn't define specific routes, resource ones. worked before 1 isn't working.

since rendering form index action, not knows create action. modify form_for as:

 form_for @cisearch, :url => your_create_action,remote:true
