No route matches "/"? - ruby-on-rails

I know this seems like a very simple error but its coming from a complex process.
Im trying to upgrade an old rails 2 app to rails 3. In my routes.rb file, i have
root :to => "home#index"
And I also have a file 'app/controllers/home_controller.rb' and a 'app/views/home/index.html.erb' so i simply dont get what could be causing this error. Upgrading to rails 3 isnt easy.
( in the home_controller.rb, i have def index
end )
Any suggestions?
**UPDATE - FULL ROUTES FILE**
SpecimenTracker::Application.routes do
map.resources :users
map.resource :session
# The priority is based upon order of creation: first created -> highest priority.
# Sample of regular route:
# map.connect 'products/:id', :controller => 'catalog', :action => 'view'
# Keep in mind you can assign values other than :controller and :action
# Sample of named route:
# map.purchase 'products/:id/purchase', :controller => 'catalog', :action => 'purchase'
# This route can be invoked with purchase_url(:id => product.id)
# Sample resource route (maps HTTP verbs to controller actions automatically):
# map.resources :products
# Sample resource route with options:
# map.resources :products, :member => { :short => :get, :toggle => :post }, :collection => { :sold => :get }
# Sample resource route with sub-resources:
# map.resources :products, :has_many => [ :comments, :sales ], :has_one => :seller
# Sample resource route with more complex sub-resources
# map.resources :products do |products|
# products.resources :comments
# products.resources :sales, :collection => { :recent => :get }
# end
# Sample resource route within a namespace:

get "home/index"
root :to => "home#index"
# See how all your routes lay out with "rake routes"
# Install the default routes as the lowest priority.
# Note: These default routes make all actions in every controller accessible via GET requests. You should
# consider removing the them or commenting them out if you're using named routes and resources.
map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id.:format'
end

The "map.connect", "map.resources" are old syntax
My Rails 3 routes.rb starts with
ApplicationName::Application.routes.draw do
Rails Routing from the Outside In: http://guides.rubyonrails.org/routing.html

Just to make sure, have you tried restarting Webrick (or whatever other server you're using). While this is very simple, it will always end up tripping you up :)
If that's not the problem, please post your log files (log/development.log).
Edit: Just seen the update to your post. Try removing the other (uncommented) lines in your routes file, line by line, until the problem is fixed.

remove the two map.connect statements. you don't need them in rails3.
and the ressources at the top should be just:
resources :users
resources :sessions

Try:
root :to => 'home#index'
Note single quotes. # has special meaning in a double quoted string in Ruby.

custom route for show action using slugs

I'm attempting to create some urls for a model that I want display. I have articles, which belong to sections which belong to issues.
I would like my URLs for the article show action to look like this:
/issue-slug/section-slug/article-slug issues articles and sections have slugs that are stored in the db.
Right now I have a backend section called 'pressroom' and I have the following routes for that. Here is the whole routes.rb file
MaskmagazineCom::Application.routes.draw do
devise_for :users, :path_names => { :sign_up => "register"}, :controllers => { :registrations => "registrations" }
# The priority is based upon order of creation: first created -> highest priority.
# See how all your routes lay out with "rake routes".
root 'magazine#index'
get 'users/' => 'users#index'
# Lobby Routes
# /log-in
devise_scope :user do
get '/sign-in' => 'devise/sessions#new'
end
# /subscribe
get 'subscribe' => 'subscribe#stepone'
get 'subscribe/sliding-scale' => 'subscribe#steptwo'
get 'subscribe/sliding-scale/subscriber' => 'subscribe#subscriber'
get 'subscribe/sliding-scale/supporter' => 'subscribe#supporter'
get 'subscribe/sliding-scale/sustainer' => 'subscribe#sustainer'
post 'subscribe/sliding-scale/:type' => 'subscribe#createSubscription'
# Pressroom Routes
get '/pressroom' => 'pressroom#index'
scope 'pressroom' do
resources :issues, :articles, :sections, :users, :authors
end
How can I pull out the show action and route it to the url that I described?
EDITED:
I've come up with what i want it to do in the routes file, but i need the corresponding controller code:
get '/:issue_slug/:section_slug/:article_slug' => 'article#show'
I'd recommend checking out friendly_id for the slugs.
for the routes, you'll want your routes to read:
# Mag Routes
get '/mag' => 'mag#index' #or wherever you're headed
scope 'mag' do
resources :issues do
resources :sections do
resources :articles
end
end
end
end

Pull out specific view on devise Rails

I'm applying a design for a Rails app, I usually works on PHP, anyway, I'm doing the reset password modifications the problem is I have the views for reset password, but not the email.
I know there is a generate devise:views which pull up even the email, the problem when I do this is this "damage" the current customizations in some part already done in this app by other programmer.
How can I pull up just the reset instructions email view on devise, so I can edit it?
Thanks.. I guess you can be more specific when you generate views of devise using
generate devise:views
Even more specific than
generate devise:views users
Also in the email the link is directed to localhost, for this issue I found this Devise: edit_password_url in password reset email is sending users to url/api/v1/
The problem is I can't make that work in my routes.rb which is here
Consult::Application.routes.draw do
devise_for :users, :controllers => { :registrations => "registrations" }
scope "/admin" do
resources :users, :controller => 'admin/users'
end
resources :players
resources :player_steps
resources :coach_steps
resources :candidates
resource :payment_notifications, :only => :show
#match 'candidates' => 'candidates#index'
match '*a', :to => 'errors#routing'
# The priority is based upon order of creation:
# first created -> highest priority.

# match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase
# This route can be invoked with purchase_url(:id => product.id)
# Sample resource route (maps HTTP verbs to controller actions automatically):

# Sample resource route with options:

# end
#
# collection do
# get 'sold'
# end
# end
# Sample resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Sample resource route with more complex sub-resources
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', :on => :collection
# end
# end
# Sample resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end
# You can have the root of your site routed with "root"
# just remember to delete public/index.html.
#root :to => "devise/sessions#new"
get 'user_type', to: 'home#user_type', as: :choose
devise_scope :user do
root :to => "devise/sessions#new"
end
# See how all your routes lay out with "rake routes"
# This is a legacy wild controller route that's not recommended for RESTful applications.
# Note: This route will make all actions in every controller accessible via GET requests.
# match ':controller(/:action(/:id))(.:format)'
end
How in the name of rails can I make this work so that I can finish this?
Rails has some helpers that can come in useful when you do something wrong, such as
rails generate model Fish
rails g controller Fishes
You can also apply this to destroying the action task if you need too
rails destroy model Fish
rails destroy controller Fishes
You can apply this to anything with rails at the front so:
rails generate devise:views
rails destroy devise:views

Rails devise not working for rails 3.2.1 on localhost

I followed each and every single step for devise to work on my localhost as discussed under this tutorial - http://www.slideshare.net/wleeper/devise-and-rails upto page 8 of 22 and I was expecting the same user login form as mentioned on the page 8 but apart from this, i am getting this error-
If i keep the comments as it is on routes.rb file,
# match ':controller(/:action(/:id))(.:format)'
then this message flags -
And when i uncomment this line it show this error-
Have very less idea about rails, as I am from PHP background, but still trying some practical tests before theory, so let me know what exactly im doing wrong.
My routes.rb file -

devise_for :users

match ':controller(/:action(/:id))(.:format)'
end
Just run a rake routes command and find this -
You are accessing the wrong url.. you should try it with
http://application/users/login
you dont have the right root url like
root :to => redirect("/users/login")

Unable to parse the csv file in ruby and rails

I am a newbie to the ruby on rails platform and I was just trying out couple of example codes.
I was trying to run this example http://goodbadtech.com/2009/05/13/ruby-on-rails-import-csv-data-into-database/
I followed all the instructions but I am getting this error
ActionController::RoutingError (uninitialized constant CsvImportController):
Please help me to bash this error.
Here is my Routes.rb
Imports::Application.routes.draw do
# The priority is based upon order of creation:
# first created -> highest priority.
get "csv_imports/csv_view"
#map.resources :imports
#map.import_proc '/import/proc/:id', :controller => "imports", :action => "proc_csv"

# match ':controller(/:action(/:id(.:format)))'
Your file, containing the class CsvImportsController should be named csv_imports_controller. I believe that is the error. In your routing, you should have
resources :csv_imports
[EDIT] On the other hand, if your controller is named ImportsController, placed in imports_controller.rb, then inside your routing, you should have
resources :imports
Rails automatically tries to tie things together based on the names. This is what makes things easy if you follow them correctly. So resources :imports will assume there is a controller called ImportsController, which can be found in app/controllers/imports_controller.rb. It is best practice to call the relevant model Import, to be found in app/models/import.rb.
Hope this helps.
(also note that the blog-post you mention is for Rails 2 and not Rails 3)

Typus route order

It used to be that you could load Typus routes exactly where you needed them by placing
Typus::Routes.draw(map)
at the appropriate point in your routes.rb file. It seems that this is no longer supported and that they're always loaded after all of the application routes. This causes problems with catchall routes which must be defined last. Does anyone know how to control the load order for typus now? Is there a way to get them defined before any of the app routes rather than after? Thanks!
I got around it by leaving my catch-all routes at the end of my apps routes.rb BUT excluding it from matching for Typus urls:
# A catch all route
match '*path' => 'content#show', :constraints => lambda{|request|
!request.path.starts_with?("/admin") # excluded if typus will be taking it...
}
This may or may now work for you...
I'm looking for the same answer.
At the moment I have resorted to copying the contents from typus's config/routes.rb and placing it into my routes.rb file, before the catchall route.
It's a horrible, hackish solution, but it's solving my immediate problem.
Example:
# TODO: KLUDGE: MANUALLY BRING THE TYPUS ROUTES IN
# Typus used to provide :
# Typus::Routes.draw(map)
# But that is no longer the case.
scope "admin", :module => :admin, :as => "admin" do
match "/" => "dashboard#show", :as => "dashboard"
match "user_guide" => "base#user_guide"
if Typus.authentication == :session
resource :session, :only => [:new, :create, :destroy], :controller => :session
resources :account, :only => [:new, :create, :show, :forgot_password] do
collection do
get :forgot_password
post :send_password
end
end
end
Typus.models.map { |i| i.to_resource }.each do |resource|
match "#{resource}(/:action(/:id(.:format)))", :controller => resource
end
Typus.resources.map { |i| i.underscore }.each do |resource|
match "#{resource}(/:action(/:id(.:format)))", :controller => resource
end
end
# END KLUDGE
# Catch all to the state page handler
match '/:page' => 'pages#show', :as => 'page'
