Question

I’m following Railscasts #228 in Rails 3.0.5 and ruby 1.9.2p180.

I have copied code near verbatim from the verbatim with the exception of changing the class name from Product to Player. I’m also skipping the last portion where Ryan adds arrows to denote the sort direction. I’m able to load the correct index page and see all of the desired URL’s with the desired parameters (direction and sort), but nothing is actually happening on click. The URL is changing, but the page is not reloading.

Here is my code:

ApplicationHelper

  def sortable(column, title = nil)  
    title ||= column.titleize  
    direction = (column == params[:sort] && params[:direction] == "asc") ? "desc" : "asc"  
    link_to title, :sort => column, :direction => direction  
  end

PlayersController

  def index
    @players = Player.order(sort_column + ' ' + sort_direction)
  end

  private

  def find_team
    session[:team] ||= Team.new
  end

  def sort_column  
    Player.column_names.include?(params[:sort]) ? params[:sort] : "name_e"  
  end  

  def sort_direction  
    %w[asc desc].include?(params[:direction]) ?  params[:direction] : "asc"  
  end

Thanks for your help!

Edit: As requested, HTML code. You can see that the link for Position is currently desc, as I am at: http://localhost:3000/players?direction=asc&sort=abb_pos. However, no actual sorting has occurred for this column, or any other column.

<th><a href="/players?direction=asc&amp;sort=name_e">Name</a></th> 
<th><a href="/players?direction=asc&amp;sort=team_e">Team</a></th> 
<th><a href="/players?direction=desc&amp;sort=abb_pos">Position</a></th> 
<th><a href="/players?direction=asc&amp;sort=height">Height</a></th> 
<th><a href="/players?direction=asc&amp;sort=weight">Weight</a></th>

Found the issue. I had the following code in my player model:

Player.rb

default_scope :order => 'name_e'

As a result, the SQL search generated looked like this:

SELECT `players`.* FROM `players` ORDER BY name_e, avg_points desc
