No slug being added with friendly id rails

When i create a new category_item_key in the db the slug isn't being added to the slug column.

here is my coding

migration file

class AddSlugToCategoryItemKeys < ActiveRecord::Migration
   def change
    add_column :category_item_keys, :slug, :string
    add_index :category_item_keys,  :slug, unique: true
  end

end

category_item_key controller

def new
 @guide = Guide.friendly.find(params[:guide_id])
 @category = Category.friendly.find(params[:category_id])
 @key = Category.friendly.find(params[:category_id]).category_item_keys.new

end

def create

 @guide = Guide.friendly.find(params[:guide_id])
 @category = Category.friendly.find(params[:category_id])
 @key = Category.friendly.find(params[:category_id]).category_item_keys.new(key_params)


  if @key.save
       flash[:info] = "Key added succesfully!"
      redirect_to @guide
  else
      render 'new'
  end
end



private


def key_params
 params.require(:category_item_key).permit(:name, :slug)
end

new.html.erb

     <%= form_for([@category, @key], url: category_item_keys_create_path) do |f| %>
       <%= render 'shared/error_messages', object: f.object %>

      <%= f.label :name, "Key name" %>
      <%= f.text_field :name %>

      <%= f.submit "Next"  %>
    <% end %>

When creating a new guide or category friendly id works just fine, with the slug being added. But for category_item_key something is going wrong.

Maybe i'm missing something. But i cant find the problem.

Just for your notice

You can rewrite to_params method in your model to generate your uniq slug

to_params
 #for instance
  your_column + your_column
end

def new
   @guide    = Guide.find params[:guide_id]
   @category = Category.find params[:category_id]
   @key      = @category.category_item_keys.new
end

def create
   @guide    = Guide.find params[:guide_id]
   @category = Category.find params[:category_id]
   @key      = @category.category_item_keys.new key_params

   if @key.save
      redirect_to @guide, notice: "Key added succesfully!"
   else
      render 'new'
   end
end

private

def key_params
   params.require(:category_item_key).permit(:name)
end

--

<%= form_for [@guide, @category, @key] do |f| %>
   <%= render 'shared/error_messages', object: f.object %>

   <%= f.label :name, "Key name" %>
   <%= f.text_field :name %>

   <%= f.submit "Next"  %>
<% end %>

If you've ran your migration (have the columns in the db), the above should work. If it doesn't, you need to post the sent params, and the response you're receiving from the server.

As an aside, you'll also want to look at how many levels you're nesting your routes...

Resources should never be nested more than 1 level deep.

Because you've got guides and then categories before you get to keys, you'll probably want to remove the category or guide param:

# config/routes.rb
resources :categories do
   resources :keys
end

I think the issue you have is likely that you're only passing [@category, @key] to your form_for. Instead, you'll need to include the @guide as well.
