Rails 3.2.13 undefined method `photos_path' with nested resources with CarrierWave -


i hoping can give me insights on how nested resources , more how tie carrierwave.

i'm getting error undefined method 'photos_path' , bit stuck on how go getting work.

i want able have following urls

create new photo

site.com/animal/dog/photos/new

show photo

site.com/animal/dog/photos/my-dog-in-the-park

should using nested form? appreciated.

my routes

root to: "home#index"  resources :animal   resources :photos end

my home view

<%= link_to "add dog photo", new_animal_photo_path(animal_permalink: "dog") %>

my _form partial

<%= form_for [@animal, @photo], :html => {:multipart => true} |f| %>   <%= f.hidden_field :animal_permalink %>   <p>     <%= f.label :title %><br />     <%= f.text_field :title %>   </p>   <p>     <%= f.file_field :image %>   </p>   <p>   </p>   <p><%= f.submit %></p> <% end %>

my photo model

class photo < activerecord::base   include activemodel::forbiddenattributesprotection    before_create :set_permalink   before_update :set_permalink    belongs_to :dog   mount_uploader :image, photouploader    def set_permalink     self.permalink = title.parameterize   end    def to_param     permalink.parameterize   end end

my animal model

class animal < activerecord::base   include activemodel::forbiddenattributesprotection    has_many :photos    scope :dog, where(name: "dog")    def to_param     permalink.parameterize   end end

my photocontroller

class photoscontroller < applicationcontroller    def show     @photo = photo.find(params[:id])   end    def new     @animal = animal.find_by_permalink(params[:id])     @photo = photo.new   end    def create     @photo = photo.new(photo_params)     if @photo.save       flash[:notice] = "successfully created photo."       redirect_to root_url     else       render :action => 'new'     end   end    def edit     @photo = photo.find(params[:id])   end    def update     @photo = photo.find(params[:id])     if @photo.update_attributes(photo_params)       flash[:notice] = "successfully updated photo."       redirect_to root_url     else       render :action => 'edit'     end   end    def destroy     @photo = photo.find(params[:id])     @photo.destroy     flash[:notice] = "successfully destroyed photo."     redirect_to root_url   end    private    def photo_params     params.require(:photo).permit(:title, :image, :animal_id)   end  end

thanks taking look. appreciated.

i've made few adjustments code.

notice i've added "s" animal

root to: "home#index"  resources :animals   resources :photos end

notice i've removed "s" animals. i've changed animal_permalink id because default expected nested resource. also, note that, in photos controller new method check "id" param, not animal_permalink param.

new_animal_photo_path(id: "dog")

in _form. set value of animal_permalink

<%= f.hidden_field :animal_permalink, value: @animal.permalink %>

this assumes photo able recognize animal_permalink attribute , you've defined animal.permalink method/attribute. i'm not familiar permalink approach, may have fiddle around bit, should steer in right direction (i set :dog_id/:animal_id attribute).

let me know how goes.
