rails和ajax请求404错误

Question

I have this error on my rails logs :

Completed 404 Not Found in 11ms
** [Raven] User excluded error: #<ActionController::RoutingError: Not Found>

ActionController::RoutingError (Not Found):
  app/controllers/schools_controller.rb:6:in `common_content'

I don't understand why, here is the code :

Show.html.erb

<%= link_to "Vérifiés (#{@count_verified})", rate_verified_path, remote: true %>

routes.rb

get '/rate_verified' => 'schools#verified_rating'

schools_controller.rb

before_filter :common_content, :only => [:show, :verified_rating]

def verified_rating
  @selected = @ratings.where(:verified => true)
  respond_to do |format|
    format.js
  end
end

verified_rating.js.erb

$('#verifie').html("<%= escape_javascript render(:partial => 'rating') %>");

Does someone could help me ?

EDIT

the common_content method :

def common_content
  @school = School.where(city_namespace: params[:city], title_namespace: params[:title]).first || raise(ActionController::RoutingError.new('Not Found'))
  @rating = Rating.new(params[:rating])
  @rating.school_id = @school.id
  @ratings = @school.ratings.desc(:created_at)
end

Answer 1

In first line of common_content method, we can see:

  School.where(city_namespace: params[:city], title_namespace: params[:title]).first || raise(ActionController::RoutingError.new('Not Found'))

Because the first part (before || ) of that code returns nil the second part is executed, which is:

    raise(ActionController::RoutingError.new('Not Found')

So the 404 is raised because no School record was found.
