Hi everyone,

I need several pages to be static but also modify when requested. I try following the railcast from Ryan at

Here what I have done!!

rails g scaffold Pages name:string permanentlink:string title:string author:string access_level:string is_published:boolean meta_description:string meta_keyword:string meta_author:string content:text

route.db get 'static/:permanentlink', :controller => 'pages', :action =>'show'

show.html.erb <p id="notice"><%= notice %></p> <p>   <%= @page.title %> </p>

<p>   <%= @page.content %> </p> <%= link_to 'Edit', edit_page_path(@page) %> | <%= link_to 'Back', pages_path %>

controller#show.rb def show   if params[:permanentlink]     @page = Page.find_by_permanentlink(params[:permanentlink])   else     @page = Page.find(params[:id])   end     respond_to do |format|       format.html # show.html.erb       format.json { render json: @page }     end   end

The error NoMethodError in Pages#show

Showing /home/jean/rail/wyw/app/views/pages/show.html.erb where line #3 raised:

undefined method `title' for nil:NilClass Extracted source (around line #3):

1: <p id="notice"><%= notice %></p> 2: <p> 3: <%= @page.title %> 4: </p> 5: 6: <p> Rails.root: /home/jean/rail/wyw

Hi everyone,

I need several pages to be static but also modify when requested. I try following the railcast from Ryan at #117 Semi-Static Pages - RailsCasts

Here what I have done!!

rails g scaffold Pages name:string permanentlink:string title:string author:string access_level:string is_published:boolean meta_description:string meta_keyword:string meta_author:string content:text

route.db get 'static/:permanentlink', :controller => 'pages', :action =>'show'

show.html.erb <p id="notice"><%= notice %></p> <p>   <%= @page.title %> </p>

<p>   <%= @page.content %> </p> <%= link_to 'Edit', edit_page_path(@page) %> | <%= link_to 'Back', pages_path %>

controller#show.rb def show   if params[:permanentlink]     @page = Page.find_by_permanentlink(params[:permanentlink])   else     @page = Page.find(params[:id])   end     respond_to do |format|       format.html # show.html.erb       format.json { render json: @page }     end   end

The error means that @page is nil, so your find is not finding anything. Have a look at the Rails Guide on debugging for ideas on how to debug your code.
