Rails partial render and devise action - ruby-on-rails

Question

In my rails app i go for example to devise sign up action (http://*:3000/users/sign_up) and get error:
No route matches {:controller=>"devise/vehicle_types", :action=>"search_vehicle_type"}
I thing it's becouse i'm in devise namespace of routing... But how can i normally render sign up view? My layout part look's so:
= render :partial => 'vehicle_types/findtype'
and this partial:
.form
= form_tag :controller => 'vehicle_types', :action => 'search_vehicle_type' do
= select("post", "MFA_ID", Manufacturer.all.collect {|p| [ p.MFA_BRAND, p.MFA_ID ] }, {:prompt => 'Марка'}, :class => "login-input man-select")
= select_tag "models", options_for_select(['Модель', nil]), :class => "login-input mod-select", :prompt => 'Модель', :disabled => :true
= select_tag "fueltype", options_for_select([['Тип топлива', nil], ['Не важно', nil], ['Бензин', 53302], ['Дизель', 53205], ['Газ', 53241], ['Гибрид', 55554], ['Электродвигатель', 52433]]), :class => "login-input fuel-select"
= text_field_tag "year", nil, :placeholder => "Год выпуска", :class => "login-input"
.submit-area
.left
= submit_tag "Выбор", :class => "orange-button"
On other pages (non-devise) all is ok, but when i go to password recovery, or sign up i get erros. But why? And how to solve it?
Also part of routes:
Oleg::Application.routes.draw do
devise_for :users
match '/search_vehicle_type' => 'vehicle_types#search_vehicle_type'
root :to => 'pages#index'
end
Also i read about links here https://github.com/plataformatec/devise/issues/471, but how for partial to do?
and rake routes | grep devise
new_admin_session GET /admins/sign_in(.:format) devise/sessions#new
admin_session POST /admins/sign_in(.:format) devise/sessions#create
destroy_admin_session DELETE /admins/sign_out(.:format) devise/sessions#destroy

new_admin_password GET /admins/password/new(.:format) devise/passwords#new

While it may not be the best style, the easiest fix to this is to use an actual path in the form_tag:
.form
= form_tag "/search_vehicle_type" do
# Rest of the form
Another alternative would be to name the route in your routes.rb file:
match '/search_vehicle_type' => 'vehicle_types#search_vehicle_type', :as => :search_vehicle_type
Then use that named route in the form_tag:
.form
= form_tag search_vehicle_type_path do
# Rest of the form
