rails 3 absolute link to generated url - ruby-on-rails-3

I am looking into generating urls which look like https://mywebsite.com/user/check_email_confirmation/46cee41bc2044104aff8cf7746687ea8
for the famous "please click this link to confirm your email".
So I have a route which I intend to use for this in my routes.rb:
resources :user do
collection do
get 'check_email_confirmation/:generated_url', :to => 'user#check_email_confirmation'
end
end
Now, my trouble is to generate the full address above. I cah generate the SHA (46cee41bc2044104aff8cf7746687ea8) part, but how do I write the "https://mywebsite.com/user/check_email_confirmation/" part in my view?
Added view's code:
<p>Please click <%= url_for(:action => 'check_email_confirmation', :controller => 'user', :only_path => false, :id => #confirmation_url) %> to confirm your e-mail address.</p>

Replace id: with generated_url:.
You could also simplify the url_foring with naming the route by as: in routes
get 'check_email_confirmation/:generated_url', to: 'user#check_email_confirmation', as: :confirmation
More on this at http://viget.com/extend/rails-named-routes-path-vs-url

get "check_email_confirmation/:id" => "users#check_email_confirmation", :as => "check_email_confirmation"

url_for adding controller and action to querystring in rails 3.2

I am trying to generate a url in an actionmailer template. An example if the url I want to generate is
http://0.0.0.0:3000/users/confirm/lNbQxzFukYtEEw2RMCA
Where the last segment is a hash to identify the user
However when I use this
<%= url_for(:controller => 'users', :action => 'confirm', :id => #user.confirmhash, :only_path => false) %>
It generates this
http://0.0.0.0:3000/assets?action=confirm&controller=users&id=ZOR3dNMls8533T8hJUfCJw
How can I get it to correctly format? I have no idea where 'assets' is coming from.
Is there an easier way to use named routes that I am missing?
I've found the answer. As I'm still learning I've missed the option to create a named route. So this this the path I've taken.
In config/routes.rb
match 'user/confirm/:id' => 'users#confirm', :as => :confirm_account
Then in my action mailer template I've used
<%= link_to "Confirm your account", confirm_account_url(#user.confirmhash) %>
Which passes the :id into the controller action.

Using generated paths with resources in Rails

I have following routes defined:
CyberTrackRails3::Application.routes.draw do
scope "(:locale)", :locale => /en|de|nl/ do
resources :login do
get 'index', on: :collection
get 'check', on: :collection
end
end
end
Now, url_for(:controller => 'login', :action => 'check'), gives me the correct url, en/login/check.
Using login_check_path however doesn't work. How do I make this work?
I've tried replacing get 'index', on: :collection with match 'check' => 'check' but that doesn't work. Neither does match 'check' => 'login#check'.
since you're adding an action to a resource, i think the automatically generated name is going to be reversed, ie 'check_logins_path' (see adding-more-restful-actions)
do you need login_check_path specifically? if so, you should be able to define the path outside of the resources :login block, ie
match '/login/check' => 'login#check', :via => :get, :as => 'login_check'
and like Fivell suggested, rake routes will show you the automatically generated name for a route.

Routing with id and handle in Rails

I'm trying to set up rails to use both the ID and the Handle (which is just an URL safe version of the title) of a blog post in the route.
match '/articles/:id/:handle', :to => 'articles#show'
resources :articles
This works, of course -- but I can't seem to set up the to_param method in the model os the longer URL -- with the handle attached, is the default.
This doesn't work (not that I really expected it to):
def to_param
"#{id}/#{handle}"
end
I get a No route matches {:action=>"edit", :controller=>"articles", error. I also tried just using the handle, but then Rails generates links to the resource just using the handle and not the ID. I know I can do it with a - in stead of a /, but I prefer the /. Any way to make this work? If I have to add some extra paremeters to my link_to helpers, that's okay.
Did you try to pass a Hash to link_to?
link_to "Link", {:id => #article.id, :handle => #article.handle}
Update
You have to modify your routes:
match '/articles/:id/:handle', :to => 'articles#show', :as => :article_with_handle
and use the following helper to generate the link:
link_to "Link", article_with_handle_path(:id => #article.id, :handle => #article.handle)
You can override the helper to simplify things:
def article_with_handle_path(article)
super(:id => article.id, :handle => article.handle)
end
and use it like this:
link_to "Link", article_with_handle_path(#article)
Okay, here's what I did to remove the query string problem from the answer above:
Changed the route to this:
match '/articles/:id/:handle' => 'articles#show', :as => :handle
Removed the to_param method from the model and then generated the link like this:
link_to 'Show', handle_path(:handle => article.handle, :id => article.id) %>
That works, but could be condensed, obviously, with the helper above. Just change the one line to: args[1] = handle_path(:id => args[1].id, :handle => args[1].handle)

Trying to create a POST request but getting No route matches [GET]

I'm trying to do something similar to Railscasts #255 but I'm getting a No Route error:
In Ryan's routes.rb file:
post "versions/:id/revert" => "versions#revert", :as => "revert_version"
In in the controller where he uses the route, versions_controller.rb
link = view_context.link_to(link_name, revert_version_path(#version.next, :redo => !params[:redo]), :method => :post)
redirect_to :back, :notice => "Undid #{#version.event}. #{link}"
In my routes.rb
post "/approve/:id" => "listings#approve", :as => "listing_approve"
and view where I use my link:
<%= link_to 'Approve Content', listing_approve_path(#listing), :method => :post %>
My tests return to me a ActionController::RoutingError: No route matches [GET] "/approve/1"
If I leave the method as a GET everything works.. Using rails 3.1.0rc5. Any guidance as to what I'm doing wrong here would be very much appreciated..
EDIT: routes.rb file (the last line is set as match right now to work)
RLR::Application.routes.draw do
root :to => "home#index"
devise_for :users, :controllers => { :registrations => "registrations" }
devise_for :users
match '/user' => "layouts#index", :as => :user_root
resources :users, :only => :show
resources :layouts, :only => [:index, :show]
resources :listings
resources :features
resources :orders
match "/preview/:id" => "listings#preview", :as => "listing_preview", :via => "get"
match "/approve/:id" => "listings#approve", :as => "listing_approve"
end
Hmmmm, it looks right to my eye. The test sounds like it is generating a GET instead of a POST though, so it might be a problem with the link_to call. You've got :method => :post there, so it should be fine. http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to seems to indicate that link_to will generate some javascript to make a POST call on click (and that users with javascript disabled will get a normal GET link unless you use :href="#"), so it might be because your test engine isn't running the javascript.
You can fix this by changing it to a button that submits a hidden form, but that might not be the visual representation you want.
It might be a precedence thing - the first matching route definition in routes.rb is used, so if you have a resources route or something like that it may be matching on that first.
I got the same problem in my rails application and I solved it the same way you did by doing a via: :get on the match instead of a via: :post. I think for some reason when you send a request in the format of /something/:id it will automatically assume its a [GET] request and search for a get route. This of course will cause problems in your routes if you have it as a :POST.
If anyone has a better solution or idea as to why you cannot send a post request in the format '/something/:id' let me know please.

Rails 3 Route: button_to HTML INPUT Action not working

I have a strange problem that I think has to do with routes.
In my "view" I have this:
<%= button_to "New Item", new_proposal_pitem_path(#proposal), :method => :get %>
I want to click the "New Item" button, and create a new pitem for a proposal. This generates the HTML I would expect:
<form method="get" action="/proposals/1234/pitems/new" ...><input ...></form>
However, what really happens is, when I click on the button it attempts a GET on /proposals/1234 rather than /proposals/1234/pitems/new. This gives me a "show" page rather than a "new" page. Interestingly, I can manually put the {site}/proposals/1234/pitems/new directly into the web browser HTTP address and get what I want (the "new" page). But rails is, on its own, translating it first to /proposals/1234 if I leave it to its own in response to the button click.
To make this more mysterious, I have a similar item on the same form which looks exactly the same way:
<%= button_to "New Payment", new_proposal_payment_path(#proposal), :method => :get %>
which generates the same HTML as the other case:
<form method="get" action="/proposals/1234/payments/new" ...><input ...></form>
But this one works! It takes me right to /proposals/1234/payments/new when I click the button, just like I'd expect. I just don't understand what makes these behave differently.
My full routes file looks like this:
TCoB::Application.routes.draw do
resources :proposals do
resources :pitems, :payments
get 'list', :on => :collection
end
resources :pitems do
get 'list', :on => :collection
end
resources :invoices do
resources :iitems, :payments
get 'list', :on => :collection
end
resources :iitems do
get 'list', :on => :collection
end
resources :payments do
get 'list', :on => :collection
end
resources :ids
resources :clients do
resources :proposals, :invoices
# Route GET /cients/list
get 'list', :on => :collection
get 'list_proposals', :on => :collection
get 'list_invoices', :on => :collection
end
get "home/index"
root :to => "home#index"
end
Can someone shed light on this issue?
Thanks!
Small helper method that uses JavaScript:
def button_link_to(name, url)
"<button type=\"button\" onclick=\"window.location.href='#{url}';\">#{h(name)}</button>".html_safe
end
button_link_to "New Item", new_proposal_pitem_path(#proposal)
