I'm very new to RoR and I'm trying to get a very basic site going. I have my home page working okay, but when I try to add a new page, I keep getting "No route matches" in the log. Here is the output from rake routes:
Prefix Verb URI Pattern Controller#Action
inventing_index GET /inventing/index(.:format) inventing#index
ideas_index GET /ideas/index(.:format) ideas#index
root GET / ideas#index
However, when I go to mysite.com/inventing or mysite.com/inventing/index I get the no route matches error. mysite.com/ shows the app/views/ideas.erb as hoped. All I did was rails generate controller inventing index. Is there something else I have to do to activate the route?
I'm running ruby 2.0.0p247 and rails 4.0.0 with passenger/apache on centos 6. I installed all the ruby/rails/passenger stuff, so its possible something isn't setup properly.
Thanks
EDIT: Here is my routes.db file:
Rortest::Application.routes.draw do
get "inventing/index"
get "ideas/index"
root to: 'ideas#index'
end
tldr: Your problem is probably the route. Change get 'inventing/index' to get 'inventing/index'=> 'inventings#index' to correctly point the route to your controller action.
There are four things you need to do when adding a new page/route. I usually do them in this order for static pages:
1) Create a controller with the appropriate action for each page
You already did this with rails generate controller inventing index, but make sure that:
In your app/controllers folder, you do indeed have a file called inventings_controller.rb
In inventings_controller.rb, you have at least this:
class InventingsController < ApplicationController
def index
end
end
2) Create a view for each controller action
Make sure that:
In your app/views/inventings folder, you have a file called index.html.erb
Puts some simple HTML in that file, like <h1>Testing123</h1>, just so you can see if it's working.
3) Add a route for each controller action
It looks like this may be the problem. In your routes.rb file, you'll need this:
get 'inventing/index' => 'inventings#index'
Your root to works because it's actually pointing directly to your controller action, but rails isn't smart enough to guess that inventing/index should go to the index action in your inventing**s** controller.
4) As others have suggested, restart your rails app
You can do this with ctrl+c at the command line, then rails s again to start it back up.

I am learning how to login from Rails and I wanted to know one thing:
I have several files which I want to show when a certain condition is met, in this case logging in will redirect me to another file called starter.html.erb
I am trying to redirect it through both the controller and the routes files and I get the following error:
No route matches [GET] "/app/views/usuarios/starter.html.erb"
Can you please tell me what I'm doing wrong? Thanks!
Controller portion:
redirect_to search_starter_path
routes.rb portion:
get "/search/starter" => redirect("/app/views/usuarios/starter.html.erb")
You have to use the controller#action syntax to redirect. Example: if your controller is usuarios_controller.rb you should have inside an action named starter. Then in your routes.rb put this entry:
get "search/starter" => 'usuarios#starter'
I am creating a simple suggestion box app (to learn Rails) and am getting the following Rails routing error when I go to "/suggestion-boxes" running on my local machine (localhost:3000)
"Routing Error
No route matches [GET] "/suggestion-boxes"
In my routes.rb file I have:
SuggestionBoxApp::Application.routes.draw do
resources :suggestion_boxes
end
This is what I get when I run rake routes:
suggestion-box-app$ rake routes
suggestion_boxes GET /suggestion_boxes(.:format) suggestion_boxes#index
POST /suggestion_boxes(.:format) suggestion_boxes#create
new_suggestion_box GET /suggestion_boxes/new(.:format) suggestion_boxes#new
edit_suggestion_box GET /suggestion_boxes/:id/edit(.:format) suggestion_boxes#edit
suggestion_box GET /suggestion_boxes/:id(.:format) suggestion_boxes#show
PUT /suggestion_boxes/:id(.:format) suggestion_boxes#update
DELETE /suggestion_boxes/:id(.:format) suggestion_boxes#destroy
However, if I modify my routes file to
SuggestionBoxApp::Application.routes.draw do
get "suggestion-boxes" => "suggestion_boxes#index"
end
Then the page "/suggestion-boxes" displays as per the index action in my SuggestionBoxesController.
I tried restarting my server but this had no impact. While I of course can go with using GET, this error makes no sense, and I would like understand what is causing it.
Any insights would be very much appreciated.
The error is that you are not renaming the REST route, instead the controller one.
Try declaring
resources :suggestion_boxes, :as => "suggestion-boxes"
in your config/routes.rb file.
Somewhere in your code you are calling to suggestion-boxes controller which does not exist. Your controller is suggestion_boxes, spelling. So where every you have "suggestion-boxes" you should replace with "suggestion_boxes". The code that you added create an alias that matches 'suggestion-boxes' to the index action of the suggestion_boxes controller so this resolves it if it is your desired affect. But simply fixing your spelling would resolve your problem. I usually use the second approach if I want the change the URL that user see. Have a look at the routing doc for a better understanding
Hi this is ROR beginner's question.
I have creat controller.rb and view hello.rhtml following the tutorial, but when I try to open localhost:3000/say/hello, it come up with with error: No route matches [GET] "/say/hello"
could any one advice please?
Well you need to setup a route for that in your config/routes.rb file.
For first try i would say use a script generator, enter on the command line as being in the project library > rails g controller helloworld index. This will create a route for itself, and a controller file.
After this script runs, there should be a line in your config/routes.rb
Cloud::Application.routes.draw do
get "helloworld/index"
end
Then you need to enter localhost:3000/helloworld/index in your browser url bar. Then ( as default ) rails will render the view located in app/views/helloworld/index.*. If you want to change this behaviour, go to the helloworld controller.
For more info there is a useful guide: ROUTING GUIDES
You need to define a route definition so that the URL you are requesting gets mapped to an action in the controller you have created which would render hello.rhtml. Say your controller name is says_controller.rb (thats how Rails gives the filename). In that if you define and action hello which would by default render hello.rhtml, then the fallback routes which are defined in the routes.rb file at the end would make a request to say/hello to look for the say_controller and hello action, thus rendering hello.rhtml.
For detailed help you can refer to the Rails Guides. There is a lot of helpful material and it is explained very well.
I started developing RoR recently and the best practise I got was the tutorial # rails for zombies and video's # railscasts. I suggest you watch some / make some and you get a general idea how to get started :)
-edit- on this issue: You're trying to render the hello view from the say controller.
since routing is handled by default on :controller/:action, do you have a action called hello in say? No action means no route means no view rendered.
class SayController < ApplicationController
def hello
#do nothing or add some code
logger.debug "I'm in the say controller, hello action!"
end
end
This should get it to render the hello file. You might want to take a look at restful actions / crud though, rails uses those by default.
I'm new to Ruby on Rails and am doing my first tutorial and am running the latest version of rails 3 and ruby 1.9.2. After creating my controller and navigating to http://localhost:3000/say/hello I'm receiving a blank page. I do see the Welcome to Rails message when I just go to http://localhost:3000. I've done some Google searches and people have similar problems but there is no clear fix. I've never really worked with MVC before so the concept of routing is fairly new to me.
Below is my controller:
class SayController < ApplicationController
def hello
end
def goodbye
end
end
My view:
<h1>Say hello to Rails!</h1>
You should delete the public/index.html file as that will mess with your routing and display by default. Have you set up your routes already, and what is the exact location and filename of the template?
You will need something like in your config/routes.rb file to correctly route that url to your template/view:
match '/say/hello' => 'say#hello'
First delete the index.html file from your public folder. Then, go to the app/views and check the views for the say controller. You should have a hello.html.erb.
The answer to your particular question was answered already by Bitterzoet, but I thought you might want some alternative learning resources.
I'm not sure which tutorial you're starting with, but I find it odd that they're not using RESTful routes. You can find out what routes you have set up at the moment by going to the console and typing "rake routes". If you would like a different tutorial, I recommend the one here:
http://www.wiki.devchix.com/index.php?title=Rails_3_Curriculum
I'd also recommend http://railsforzombies.org/ as a good first-time rails experience.
A fun general line to add to config/routes is:
match ':controller(/:action(/:id(.:format)))'
While developing, this will allow you to display the controller/action in address bar for ALL controller/action/id.format etc.
Like Bitterzote wrote, if controller is "say" and action is "hello", http://localhost:3000/say/hello .
If you use controller "say" and action "move", http://localhost:3000/say/move .
I've found this route to be very useful during development, but change this if you launch your application! (Rails warns: "Note: This route will make all actions in every controller accessible via GET requests.")
I'm using Rails 3
I have a controller called subscriber_controller.rb
I just added an action called "def houston" and added this to my routes file
match '/houston' => 'subscriber#houston'
get "subscriber/houston"
but whenever I try to go to "http://localhost:3000/houston" which was the goal i get the error
Routing Error
No route matches "/houston"
What else do I need to add to the routes file to find the correct action in the controller and have the url work as http://localhost:3000/houston ?
What does "rake routes" give you?
I tried the same thing and it worked.
Check that you saved your routes file.
