By default, when displaying pagination numbers, the url looks like /controller/action/page:number. In my application I have defined a route:
Router::connect('/:categ', array('controller' => 'posts', 'action' => 'index'), array('categ' => '[a-zA-Z]+'));
I want the number link to be something like /:categ/:page.
I've tried with
Router::connectNamed(array('page'));
but has no effect.
Am I missing something?
You must using pagination options with url params:<?php $this->Paginator->options(array('url' => 'some params')); ?>

I'm creating a customisable nav menu for our site and have run into the following problem.
I need to generate a URL to any controller and action on the site and optionally pass it parameters. I was able to do the former by simply saying:
url_for(:controller => nav[:controller_name], :action => nav[:action_name])
which is great for sending you to {controller}/{action}. eg. news/articles
Throwing options in suddenly changes the game. Now I need to send you to something like:
{controller}/{action}/{category}/{slug}/{id}
eg. news/articles/world-domination/montana-max-vows-revenge/12345
the helper for the above would be something along the lines of:
news_article_path('world-domination', 'montana-max-vows-revenge', '12345')
and I haven't been able to replicate that in a vanilla url_for due to the arguments.
What I have done, and I don't really like is:
url_for(send("#{nav[:controller_name]}_#{nav[:action_name]}_path", *nav[:options]))
which generates the helper using send and then passes it a kwargs list. I'm sure there's a better way to do that surely?
You can do this cleanly if you are able to name the options (split here over lines for legibility):
url_for({
:controller => nav[:controller_name],
:action => nav[:action_name]
}.merge(nav[:options] || {}))
where
nav = {
:controller_name => 'news',
:action_name => 'articles',
:options => {
:category => 'world-domination',
:slug => 'montana-max-vows-revenge',
:id => '12345'
}
}
So I need to hit a url like mydomain.com/proxies/www.msn.com in order to fulfill some ajax requests for an API
In my route I have
get "/proxies/:url" => "proxies#get"
and I in the controller I have
url_contents = Net::HTTP.get(URI.parse(params[:url]))
which if i put /proxies/www i get
undefined method `request_uri' for #<URI::Generic:0x3f89508 URL:www>
if i put /proxies/www.msn.com
I get
No route matches [GET] "/proxies/www.msn.com"
You have two separate problems here:
You're trying to treat a URL without a scheme as an HTTP URL.
Your /proxies route won't match :urls with dots and slashes the way you're expecting it to.
For the first one, you'll have to add the schema manually:
url = 'http://' + params[:url]
content = Net::HTTP.get(URI.parse(url))
For the second one, you can use a splat-route to deal with embedded slashes and :format => false to keep Rails from trying to treat .com, for example, as a format:
get '/proxies/*url' => 'proxies#get', :format => false
If you use :url, Rails will see embedded slashes as component separators and that's probably not what you want. Without the the :format => false, Rails will try to interpret .X (for any X) as a format (just like .html, .json, ...) rather than as part of the URL.
This is applicable for rails-2
The problem is with the dot(.) I guess. Ive tried something like below and it worked.
#routes.rb
map.get_proxy 'proxies/:url', :controller => "Proxies", :action => "get", :requirements => { :url => /.*/ }
#view file
#Here dot(.) are needed to replace with its encoded string %2E
<%= link_to 'Get The Site', get_proxy_url('www.msncom') %>
#Proxies Controller
#After receiving the url the %2E need to conovert to dot(.) again.
url_contents = Net::HTTP.get(URI.parse('http://'+params[:url]))
modified as stated by #mu.
match '/proxies/:url' => 'proxies#get', :as => :proxies_get
Using github like chain routes in rails
I have URLs similar to this:
'localhost:3000/document_managers/[:module_name]'
'localhost:3000/document_managers/[:module_name]/1/2/3/.' # can be any level deep
Here is the route definition for them:
map.connect '/document_managers/:module',
:controller => "document_managers",
:action => :new_tree,
:module => ["A","B","C"]
map.connect '/docuemnt_managers/:module/*path',
:controller => "document_managers",
:action => "new_tree",
:module => ["A","B","C"]
Here is the problem:
The idea that module name value can't be anything except from the
given above array i.e("A","B","C") like at any time the URL must be something like
localhost:3000/document_managers/A/1 or
localhost:3000/document_managers/B/221/1 or
localhost:3000/document_managers/C/121/1
but that not the case even though
localhost:3000/document_managers/D/121/1 is treated as valid url
and module is set to D even though the "D" is not in listed array
above
I want the the URL localhost:3000/document_managers/A to
also redirect to same action i.e new_tree if the extra parameter isn't
provided as in the URL contain extra parameters
localhost:3000/document_managers/C/121/1 then the URL is redirected
appropriately to the desired controller and action but if the URL only
contain the path until the module name the Rails return a routes
ActionController::UnknownAction I don't know why as I have already
defined the controller and action.
In Rails 3.1, you can do this in your routes file to get what you want:
match '/document_managers/:module',
:controller => "document_managers",
:action => :new_tree,
:constraints => {:module => /[ABC]/}
I am generating a url in my controller accessed from the relative path "/hangouts/test", for a url on an external site (facebook). I want to use url_for and pass in params using hashes so it can escape them. The URL I want is this:
http://www.facebook.com/connect/prompt_permissions.php?api_key=6aca22e72866c7eaaedfb15be69c4b93&...
Using this, however:
url_for(:host => "www.facebook.com/connect/prompt_permissions.php?", :api_key => Facebooker.api_key, :next => test_hangouts_url, :cancel => root_url, :ext_perm => "publish_stream")
I instead get my current path of /hangouts/test thrown in there:
http://www.facebook.com/connect/prompt_permissions.php/hangouts/test?api_key=6aca22e72866c7eaaedfb15be69c4b93&...
As you can see, I don't want "/hangouts/test" to be in there - played a bit with the options in the API docs but stumped, anybody know how to use url_for without it inserting the current path? Thanks!
You shouldn't be using the hash form of url_for to generate links outside of your application.
Instead you should just be using the string version form:
url_for "http://www.facebook.com/connect/prompt_permissions.php?api_key=6aca22e72866c7eaaedfb15be69c4b93&next=#{test_hangouts_url}&cancel=#{root_url}&ext_perm=publish_stream"
url_for will use the current action controller/action/id unless the hash given to url_for contains one of those arguments. url_for will then generate a url from a route that matches the arguments given in the hash. The arguments to url_for used in the question generates a valid url, because it can match a route using the current controller/action. You will not be able to generate the url you want with the hash form of url for without matching a route. Providing a controller in the hash you give url_for should match the default routes that rails generates for you when you create an application, but that's not very DRY.
The better solution is to use a named route:
map.prompt_fb_permissions "/connect/prompt_permissions.php",
:host => "www.facebook.com", :controller => nil, :action => nil
then you can use the following in place of url_for whenever you want to generate this this url.
prompt_fb_permissions(:api_key => Facebooker.api_key, :next => test_hangouts_url,
:cancel => root_url, :ext_perm => "publish_stream")
You left out the controller parameter, which is why it's automatically adding your controller path ("/hangouts/test"), to your base host.
Try this:
url_for(:host => "www.facebook.com", :controller=> "/connect/prompt_permissions.php", :api_key => Facebooker.api_key, :next => test_hangouts_url, :cancel => root_url, :ext_perm => "publish_stream")
So we've got a legacy system that tracks places with IDs like "Europe/France/Paris", and I'm building a Rails facade to turn this into URLs like http:// foobar/places/Europe/France/Paris. This requirement is not negotiable, the number of possible levels in unlimited, and we can't escape the slashes.
Setting up routes.rb for http://foobar/places/Europe is trivial:
map.resources :places
...but http:// foobar/places/Europe/France complains "No action responded to Europe". I tried:
map.connect '/places/:id', :controller => 'places', :action => 'show'
...but this gives the same result, as apparently the :id ends at the first '/'. How do I make the ID cover anything and everything after the "places"?
Have a look at the Routing Guide for full documentation:
http://guides.rubyonrails.org/routing.html
Specifically section "4.9 Route Globbing".
But I think what you really want to do is declare your route like:
map.connect '/places/*id', :controller => 'places', :action => 'index'
Called with a URL like
/places/foo/bar/1
Yields a params[:id] => ["foo", "bar", "1"]
Which you could easily (re)join with "/" to yield the full string you want "foo/bar/1" (you will probably have to re-insert the leading slash manually.
That should get you going.
I tweaked Cody's answer above slightly to come up with this:
map.place '/places/*id', :controller => 'places', :action => 'show'
map.connect '/places/*id.:format', :controller => 'places', :action => 'show'
By using map.place instead of map.connect, Rails knows what resource we're dealing with and generated place_url, place_path etc helpers correctly.
Now, the 2nd line should work but doesn't thanks to the bug above, so here's a workaround for places_controller.rb that manually splits the ID and sets the format, defaulting to XML:
id, suffix = params[:id].join('/').split('.')
params[:format] = suffix ? suffix : "xml"
