How to make a button?

Rails
1

I made a button using “<%= button_to “New”, :action => “click” %>” and
have
a method in controller as:
def click
end
In router file i had added resources as "
resources:
posts" .In app/view/posts/click.html.erb file holds simple hello
message,but
when i click on the button it says:

                 No route matches {:controller=>"posts",

:action=>“click”}.

Click isn’t one of the REST states, so you will have to add that to
your routes. In Rails 2.3, this looks like this:

map.resources :posts, :member => { :click => :get }

In Rails 3, you would do:

resources :posts do
member do
get ‘click’
end
end

resources: posts just gives you the standard routes. If you want a
non-standard one you have to add it yourself. See the Rails Guide on
Routing for more information.
You can type
rake routes
to find what routes are defined. If you do that you will find that
posts/click is not there at the moment, so you get the error.

I have just realised that the OP here is John Shelfer who has already
been advised to study that guide in order to understand routing.
John, assuming that you did study that guide, please ask for
clarification of which bits you did not understand. It will be better
to get a good understanding rather than just have those here help you
out each time you have a trivial problem.

That is the result of following advice without understanding that
advice. The above syntax is explained in section 2.9.1 of the rails
guide on routing and expects an id to be passed, which is not what you
want.

As has been stated several times you can use rake routes to see what
routes you have declared, and you will see that posts/click is not one
of them.

 rake routes gave and following and it seems posts/click is there.
  posts_index GET    /posts/index(.:format)     {:action=>"index",

:controller=>“posts”}
click_post GET /posts/:id/click(.:format) {:action=>“click”,
:controller=>“posts”}
posts GET /posts(.:format) {:action=>“index”,
:controller=>“posts”}
POST /posts(.:format) {:action=>“create”,
:controller=>“posts”}
new_post GET /posts/new(.:format) {:action=>“new”,
:controller=>“posts”}
edit_post GET /posts/:id/edit(.:format) {:action=>“edit”,
:controller=>“posts”}
post GET /posts/:id(.:format) {:action=>“show”,
:controller=>“posts”}
PUT /posts/:id(.:format) {:action=>“update”,
:controller=>“posts”}
DELETE /posts/:id(.:format) {:action=>“destroy”,
:controller=>“posts”}

If you just want a static route (which I think you do) then have a
look at section 3.3

   match ':posts/:click'         didn't work as per tutorial there.

This time make sure that rake routes shows the result you expect. If
you still cannot get it to work post what you have tried and what you
see in rake routes.
I just want a simple button at click which will show the Hello message in
/app/views/posts/click.html.erb

After reading routing tutorial ,made some changes.Button is created
using
“<%= button_to “New”, :action => “click” %>” .When i clicked the button
error is:
No routes matches “/posts/click”

In router.rb ,i added a route to click action of controller as but
error is
not resolved yet.

Check::Application.routes.draw do
get “posts/index”
resources :posts do

end
get ‘posts/click’

The priority is based upon order of creation:

first created -> highest priority.

Sample of regular route:

match ‘products/:id’ => ‘catalog#view’

Keep in mind you can assign values other than :controller and

:action

Sample of named route:

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):

resources :products

Sample resource rwith_user/:uoute with options:

resources :products do

member do

get ‘short’

post ‘toggle’

end

collection do

get ‘sold’

end

end

Sample resource route with sub-resources:

resources :products do

resources :comments, :sales

resource :seller

end

Sample resource rwith_user/:uoute 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 => “welcome#index”

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

Note that it has an id in there, as I said.

 PUT  /posts/:id(.:format)    {:action=>"update",

:controller=>“posts”}
DELETE /posts/:id(.:format) {:action=>“destroy”,
:controller=>“posts”}

Once again you have taken advice (in this case mine) without
understanding what is being suggested. I should have directed you to
section 3.7. If you had read and understood the guide you would have
seen this and not been led astray by my bad advice.

map.root :controller => “controller_name”, :action => “Index”

map.connect ‘:controller/:action/:id’
map.connect ‘:controller/:action/:id.:format’

Did you try this?

Once again I have to ask whether the route appears when you do
rake routes
Your first action should be to do that and make sure the route appears
there. If it does not then experiment with routes.rb until it does
appear in rake routes.

Did you remember to restart the server after editing routes.rb?
