No slug being added with friendly id rails

Question

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.

Please update your question with `category_item_key.rb` model code. — Pavan, Jan 12 '16 at 09:51
I forgot to add `extend FriendlyId friendly_id :name, use: :slugged` into my model! — Rob, Jan 12 '16 at 11:36

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.

The variables don't work now because they arer't using friendly.find. and thanks for the side note – Rob Jan 12 '16 at 11:13

Then just put `friendly_id: [[column]], use: [:slugged, :finders]` in your model – Richard Peck Jan 12 '16 at 11:14
adding `extend FriendlyId friendly_id :name, use: :slugged` into my model did the trick (swear i checked it was there). Thanks for your help. You showed me a cleaner way of coding and stopped me from creating a nested resource nightmare – Rob Jan 12 '16 at 11:39

haha thanks man. A pro tip - you don't even need that in your model; if you go to `config/initializers/friendly_id`, you can set `config.use :slugged` which applies to all models. So you'll just be able to use `friendly_id :x` in your model with inpunity – Richard Peck Jan 12 '16 at 11:41

I'll have to use that to save this headache happening again! Hate to do this but do you think you can checkout my other question that I was on before this problem sprung. http://stackoverflow.com/questions/34736173/edit-page-to-display-all-category-names-with-edit-inputs-on-each/ You seem like you would know exactly what to do – Rob Jan 12 '16 at 11:48
Sure, let me check it out – Richard Peck Jan 12 '16 at 11:49
btw if the answer fixed it for you, you may wish to accept it so that others don't get confused – Richard Peck Jan 12 '16 at 12:06

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
