ruby on rails - Devise and helper for custom form builder -


i created custom form builder devise sign form.

form looks this, , works fine: 

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), builder: bootstrapformbuilder) |f|    <%= f.text_field :username, :autofocus => true %>   <%= f.email_field :email %>   <%= f.password_field :password %>   <%= f.password_field :password_confirmation %>    <%= f.submit "sign up", class: "btn btn-default" %> <% end %>

now want create helper named bootstrap_form_for. in application helper wrote (just test it):

module applicationhelper   def bootstrap_form_for(record, options = {}, &block)     form_for(record, options = {}, &block)   end end

when instead of form_for insert bootstrap_form_for error: undefined method 'users_path' #<#<class:0x007f9eb40bc728>:0x007f9eb40bb9b8> in bootstrap_form_for line.

error page title: nomethoderror in devise::registrations#new

do know why?

problem here:

module applicationhelper   def bootstrap_form_for(record, options = {}, &block)     form_for(record, options = {}, &block)   end end

it should be:

module applicationhelper   def bootstrap_form_for(record, options = {}, &block)     form_for(record, options, &block)   end end
