Heroku website crashes with Rails 3.2.9 and route constraint
heroku, ruby, ruby-on-rails, ruby-on-rails-3, ruby-on-rails-3.2
Solution
Can you try out the following versions in your Gemfile:
# Gemfile
gem 'rails', '3.2.9'
gem 'high_voltage', '~> 1.2.1'
gem 'thin'
# ...
The `1.2.1` release of High Voltage has the root route constraints baked into it. This will allow you to remove the routes completely from your `config/routes.rb` file.
Just set up an initializer for High Voltage:
# config/initializers/high_voltage.rb
HighVoltage.route_drawer = HighVoltage::RouteDrawers::Root
I deployed the above to a Cedar app on Heroku and it ran as expected.
Problem
My website, hosted in Heroku, has been working fine with Rails 3.2.8. I'm using a route constraint class with the HighVoltage gem for static (mostly) webpages: routes.rb: ``` get "/*id" => "high_voltage/pages#show", constraints: Constraints::StaticPage.new ``` I have a file in `/lib/constraints/static_page.rb`: ``` module Constraints class StaticPage def matches?(request) File.exist? file_path(request.path) end private def file_path(view) static_page_views_dir.to_s.concat("#{view}.html.erb") end def static_page_views_dir Rails.root.join('app', 'views', 'pages') end end end ``` Problem is, I just updated to Rails 3.2.9 and did a `git push heroku` and my app crashed :( ``` my-host:my-site scott$ heroku ps === web: `bundle exec rails server -p $PORT` web.1: crashed 2012/11/14 12:14:41 (~ 2s ago) ``` Apparently, Ruby/Heroku can't find my `Constraints::StaticPage` class. I have it `require`d at the top of my `routes.rb`: ``` require 'constraints/static_page' ``` Did something change in Rails 3.2.9 so that no longer works with Heroku? Locally everything works fine, just not in Heroku. If I take out that constraint in my route, everything works perfect (aside from not having those constraints). Here's my `heroku logs` output: ``` 2012-11-14T20:14:36+00:00 app[web.1]: DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins!
