ruby - rails : Routing Error - No route matches [GET] "/posts/new" -

i'm creating simple crud , trouble create method.

error

no route matches [post] "/usuarios/new"

this controller:

controller

    class articlescontroller < applicationcontroller  def index       @articles = article.all    end  def show        @article = article.find(params[:id])    end  def new    @article = article.new  end  def create    @article = article.new(article_params)    if @article.save      redirect_to @article    else      render 'new'    end  end  private    def article_params      params.require(:article).permit(:title, :text)    end 

my new.html.reb file :

new.html.erb

<%= form_for :article |f| %>   <p>     <%= f.label :title %><br>     <%= f.text_field :title %>   </p>    <p>     <%= f.label :text %><br>     <%= f.text_area :text %>   </p>    <p>     <%= f.submit %>   </p> <% end %> 

my routes.rb file :

routes.rb

rails.application.routes.draw   'welcome/index'   resources :articles   root 'welcome#index' end 

anybody can me?

most part of post redundant in context. seems try call new_usarios_path, in case must define route in routes.rb file:

resources :usarios
