ruby-on-rails - Rails 3，嵌套资源，没有路由匹配 [PUT]

Question

我真的为这个而疯狂。我一直在搜索答案并尝试我找到的所有内容，包括相关问题和 stackoverflow 上的答案，但仍然无法正常工作。

我正在使用嵌套资源，但无法使表单正常工作。我总是遇到错误，例如没有路线匹配 [PUT] "/galleries/1/photos"

表格在这里:/galleries/1/photos/1/edit

路线.rb

resources :galleries do
  resources :photos
end
resources :galleries
resources :photos

照片 Controller .rb

def new
  @gallery = Gallery.find(params[:gallery_id])
  @photo = @gallery.photos.build

  respond_to do |format|
    format.html
  end
 end

def edit
  @gallery = Gallery.find(params[:gallery_id])
  @photo = Photo.find(params[:id])
end

def create
  @gallery = Gallery.find(params[:gallery_id])
  @photo = @gallery.photos.build(params[:photo])

  respond_to do |format|
    if @photo.save
      format.html { redirect_to @photo, notice: 'Photo was successfully created.' }
    else
      format.html { render action: "new" }
    end
  end
end

def update
  @gallery = Gallery.find(params[:gallery_id])
  @photo = Photo.find(params[:id])

  respond_to do |format|
    if @photo.update_attributes(params[:photo])
      format.html { redirect_to @photo, notice: 'Photo was successfully updated.' }
      format.json { head :ok }
    else
      format.html { render action: "edit" }
      format.json { render json: @photo.errors, status: :unprocessable_entity }
    end
  end
end

_form.html.erb

<%= form_for([@gallery, @photo], :url => gallery_photos_path(params[:gallery_id]), :html => {:multipart => true}) do |f| %>
  <div class="field">
  <%= f.label :title %><br />
  <%= f.text_field :title %>
</div>
<div class="field">
  <%= f.file_field :image %>
</div>
<div class="actions">
  <%= f.submit %>
</div>
<% end %>

我也试过 form_for([@gallery, @photo], :html => {:multipart => true}) 和 form_for(@photo, :url => gallery_photos_path (@gallery), :html => {:multipart => true})

更新

这里是部分佣金路线。

gallery_photos GET    /galleries/:gallery_id/photos(.:format)          {:action=>"index", :controller=>"photos"}
    POST   /galleries/:gallery_id/photos(.:format)          {:action=>"create", :controller=>"photos"}
new_gallery_photo GET    /galleries/:gallery_id/photos/new(.:format)      {:action=>"new", :controller=>"photos"}
edit_gallery_photo GET    /galleries/:gallery_id/photos/:id/edit(.:format) {:action=>"edit", :controller=>"photos"}
gallery_photo GET    /galleries/:gallery_id/photos/:id(.:format)      {:action=>"show", :controller=>"photos"}
    PUT    /galleries/:gallery_id/photos/:id(.:format)      {:action=>"update", :controller=>"photos"}
    DELETE /galleries/:gallery_id/photos/:id(.:format)      {:action=>"destroy", :controller=>"photos"}

您不需要指定 URL，无论如何这对于更新都是错误的。尝试

<%= form_for([@gallery, @photo], :html => {:multipart => true}) do |f| %>
