this controller, (i generated controller "scaffold_controller"):

class tipocontenidoscontroller < applicationcontroller   # /tipocontenidos   # /tipocontenidos.json   def index     @tipocontenidos = tipocontenido.all      respond_to |format|       format.html # index.html.erb       format.json { render json: @tipocontenidos }     end   end    # /tipocontenidos/1   # /tipocontenidos/1.json   def show     @tipocontenido = tipocontenido.find(params[:id])      respond_to |format|       format.html # show.html.erb       format.json { render json: @tipocontenido }     end   end    # /tipocontenidos/new   # /tipocontenidos/new.json   def new     @tipocontenido = tipocontenido.new      respond_to |format|       format.html # new.html.erb       format.json { render json: @tipocontenido }     end   end    # /tipocontenidos/1/edit   def edit     @tipocontenido = tipocontenido.find(params[:id])   end    # post /tipocontenidos   # post /tipocontenidos.json   def create     @tipocontenido = tipocontenido.new(params[:tipocontenido])      respond_to |format|       if @tipocontenido.save         format.html { redirect_to @tipocontenido, notice: 'tipocontenido created.' }         format.json { render json: @tipocontenido, status: :created, location: @tipocontenido }       else         format.html { render action: "new" }         format.json { render json: @tipocontenido.errors, status: :unprocessable_entity }       end     end   end    # put /tipocontenidos/1   # put /tipocontenidos/1.json   def update     @tipocontenido = tipocontenido.find(params[:id])      respond_to |format|       if @tipocontenido.update_attributes(params[:tipocontenido])         format.html { redirect_to @tipocontenido, notice: 'tipocontenido updated.' }         format.json { head :no_content }       else         format.html { render action: "edit" }         format.json { render json: @tipocontenido.errors, status: :unprocessable_entity }       end     end   end    # delete /tipocontenidos/1   # delete /tipocontenidos/1.json   def destroy     @tipocontenido = tipocontenido.find(params[:id])     @tipocontenido.destroy      respond_to |format|       format.html { redirect_to tipocontenidos_url }       format.json { head :no_content }     end   end end 

and model:

class tipocontenido   include mongoid::document   store_in collection: "ctipocontenido"    field :nombretipo, type: string   belongs_to :aparienciacontenido   embeds_many :seccion end 

i working with:

1. ruby 1.9.3p448
2. rails 3.2.13
3. rake version 10.1.0
4. mongodb shell version: 2.2.3
5. mongoid 3.1.2

i don't understand error, because have document create in mongodb database in collection "ctipocontenido":

> db.ctipocontenido.find().pretty() {         "_id" : objectid("51edfd3fddbc8d2622000001"),         "nombretipo" : "colores suaves 3 partes",         "seccion" : [                 {                         "_id" : objectid("51edfd3fddbc8d2622000002"),                         "nombre" : "encabezado",                         "color" : "#e5e5e5",                         "borde" : "1px solid red",                         "etiqueta" : [                                 {                                         "_id" : objectid("51edfd3fddbc8d2622000003"),                                         "texto" : "título",                                         "tipoletra" : "verdana",                                         "tamanioletra" : "7",                                         "colorletra" : "#000000"                                 },                                 {                                         "_id" : objectid("51edfd3fddbc8d2622000004"),                                         "texto" : "lema",                                         "tipoletra" : "verdana",                                         "tamanioletra" : "6",                                         "colorletra" : "#000000"                                 }                         ]                 },                 {                         "_id" : objectid("51edfd3fddbc8d2622000005"),                         "nombre" : "panel izquierdo",                         "color" : "#e5e5e5",                         "borde" : "1px solid red",                         "etiqueta" : [                                 {                                         "_id" : objectid("51edfd3fddbc8d2622000006"),                                         "texto" : "título",                                         "tipoletra" : "verdana",                                         "tamanioletra" : "7",                                         "colorletra" : "#000000"                                 },                                 {                                         "_id" : objectid("51edfd3fddbc8d2622000007"),                                         "texto" : "lema",                                         "tipoletra" : "verdana",                                         "tamanioletra" : "6",                                         "colorletra" : "#000000"                                 }                         ]                 }         ] }

pd: excuse english !!

thanks in advance !! :)

you're looking in wrong places. error saying there's wrong config/routes.rb file. rails not being able figure out url matches show method in controller.

apparently rails generate scaffold_controller not edit routes.rb, you'll have hand , add following code it:

resources :tipocontenidos 

there's great tool debug rails routing here: http://guides.rubyonrails.org/routing.html#listing-existing-routes
