ruby on rails - NoMethodError in controller#new - undefined method -

i'm getting nomethoderror in new action of business_controller.

it seems acessing @business object form in view , error occurs then:

undefined method `businesses_path' 

here new method:

def new   if business.where(:user_id => current_user.id).first.blank?     @business = business.new   else     redirect_to user_businesses_path(current_user.id)   end end 

my routes are:

  resources :users     resources :businesses       member         'account'         post 'payment'         put 'update_password'         'membership'       end   end 

mind.blank's suggested changes

before_filter :check_if_user_has_business, :only => :index

   def new       @business = business.new    end    private   def check_if_user_has_business     redirect_to new_user_business_path(current_user) unless current_user.business   end 

do have route businesses_path or user_businesses_path? if have second 1 should specify url in form:

<%= form_for @business, url: user_businesses_path |f| %> 

also, if have correct associations set up, can write if statement follows:

if current_user.business.nil? # since it's has_one association 

here's how write it:

class businessescontroller < applicationcontroller   before_filter :check_if_user_has_business, only: :new    def new     @business = business.new   end    private    def check_if_user_has_business     redirect_to user_businesses_path(current_user) if current_user.business   end end
