>Not. In rails, a method within a controller is called 'an action'--not 'a method'. In the http protocol, which is the syntax everyone agrees to use over the internet, the 'method' is usually GET or POST, which specifies how data is to be sent over the internet. If you don't know the difference, do some research. Therefore, when you write: :method => :update_points that is wrong because it does not specify 'get' or 'post' for the method. By default, links use the method GET. If you want to change some data on the server, then you should specify POST. The action that the link_to goes to can be tricky to figure out. rails will automatically work out what action it should execute based on the path you specify and the method(= get or post). See the chart in section 2.2 here: http://guides.rubyonrails.org/routing.html Note that the '/photos' path will cause rails to execute a different action depending on the method. If the automatic routing doesn't work for you, you can specify the controller and the action in link_to (instead of a path): <%= link_to "Click me", {:controller => 'users', :action => 'get_info'} %> Sometimes you don't even have to specify a path and rails will still figure out where to go. See the examples in the link_to docs: http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to You have another problem, too. You used the 'named route': village_path. village_path requires an argument, which may look like this: village_path(@village). Compare that to the named route: villages_path. > So when you see :method it > The question is now: Where do i write this method?

Also, what page do you want your rails app to send back in response to the update? Do you want your app to remain on the same page? Remember that when you call an action, rails automatically sends back a page to the browser that matches the action name, e.g. rails converts update_points.html.erb. into update_points.html and sends it back to the browser. Then the browser loads the page. > > cause when i click on the link i just get : > > No route matches "/villages/12" > > When i open the /villages/12 without the method it works all fine. > My routes.rb : > > Citywar::Application.routes.draw do > > > > devise_for :users > resources :users, :only => [:index, :show] > resources :villages > root :to => 'pages#home' > > end > > So how can i solve this? > > Best regards > Genji -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
