You can do this:

Add this, into your routes.rb file.

    match &#39;/foo&#39;, :to =&gt; redirect(&#39;/foo.html&#39;)


**Update**

In Rails 4, it should use &quot;get&quot;, not &quot;match&quot;:

    get &#39;/foo&#39;, :to =&gt; redirect(&#39;/foo.html&#39;)

This can be done without triggering a redirect. Follow the steps further down to be able to route static files in `config/routes.rb` as shown in this example:


    # This route will serve public/index.html at the /login URL 
    # path, and have a URL helper named `login_path`:
    get &quot;/login&quot;, to: static(&quot;index.html&quot;)
    
    # This route will serve public/register.html at the /register
    # URL path, and have URL helper named `new_user_registration_path`:
    get &quot;/register&quot;, to: static(&quot;register.html&quot;), as: :new_user_registration


  1. Install the rails-static-router gem: https://github.com/mufid/rails-static-router#installation
  2. Restart app (first `bin/spring stop` to be sure app is completely reloaded).
  3. Start using the `static(path)` method in your `config/routes.rb`.



E.g in Rails 4 add the following route:

    get &#39;/example&#39;, :to =&gt; redirect(&#39;example.html&#39;)

Also you need to enable static files from the &#39;public&#39; directory in your configuration:

    config.serve_static_files = true

OR

    config.serve_static_assets = true


Also you might need to provide your public directory as root in NGINX configuration.

I&#39;m having trouble using the regex of the `find` command. Probably something I don&#39;t understand about escaping on the command line.

Why are these not the same?

    find -regex &#39;.*[1234567890]&#39;
    find -regex &#39;.*[[:digit:]]&#39;

I&#39;m getting a date string from ExtJS in the format: 

&gt; &quot;2011-04-08T09:00:00&quot;

when i try to deserialize this date, it changes the timezone to Indian Standard Time (adds +5:30 to the time) . This is how i&#39;m deserializing the date:

    SimpleDateFormat dateFormat = new SimpleDateFormat(&quot;yyyy-MM-dd&#39;T&#39;HH:mm:ss&quot;);
    getObjectMapper().getDeserializationConfig().setDateFormat(dateFormat);


Doing this also doesn&#39;t change the timezone. I still get the date in IST:

    SimpleDateFormat dateFormat = new SimpleDateFormat(&quot;yyyy-MM-dd&#39;T&#39;HH:mm:ss&quot;);
    dateFormat.setTimeZone(TimeZone.getTimeZone(&quot;GMT&quot;));
    getObjectMapper().getDeserializationConfig().setDateFormat(dateFormat);

How do I deserialize the date in the way in which it is coming without the hassles of Timezone?

I want to be able to create a record in the DB but then prevent Rails from making changes from that point on.  I understand changes will still be possible at the DB level.

I believe attr_readonly does what I want on an attribute level, but I don&#39;t want to have to manually specify fields... I would rather have more of a white-list approach.

Also, I know there is a :read_only option for associations, but I don&#39;t want to limit the &quot;readonlyness&quot; of the object to if it was fetched via an association or not.

Finally, I want to be able to still destroy a record so stuff like :dependent =&gt; :destroy works in the associations.

So, to summarize: 1) allow the creation of records, 2) allow the deletion of records, and  3) prevent changing records that have been persisted.

If on Ruby on Rails, I need to add a method called

    class String
      def capitalize_first
        # ...

and wonder where should the file go to?  (which directory and filename, and is any initialize code needed?)  This is for a Rails 3.0.6 project.



In Ruby on Rails, to extend the String class, where should the code be put in?

I have the following in my application controller:

and the following condition in my controller:

    if mystring.is_number?
    
    end

The condition is throwing an `undefined method` error. I&#39;m guessing I&#39;ve defined `is_number` in the wrong place...?

Path helpers generate paths with dots instead of slashes

After creating a migration file with `rails generate migration AddClientToUser` I can edit my migration file like so:

    class AddClientToUser &lt; ActiveRecord::Migration
      def self.up
        change_table :users do |t|
          t.references :client
        end
      end
    
      def self.down
        change_table :users do |t|
          t.remove :client_id
        end
      end
    end

Is this the correct way to reverse the reference column added in the migration?

This is a easy question,but I just don&#39;t get it.
I want to detect url in a string and replace them with a shorten one.

I found this expression from stackoverflow,But the result is just `http` 

 

    Pattern p = Pattern.compile(&quot;\\b(https?|ftp|file)://[-a-zA-Z0-9+&amp;@#/%?=~_|!:,.;]*[-a-zA-Z0-9+&amp;@#/%=~_|]&quot;,Pattern.CASE_INSENSITIVE);

            boolean result = m.find();
            while (result) {
                for (int i = 1; i &lt;= m.groupCount(); i++) {
                    String url=m.group(i);
                    str = str.replace(url, shorten(url));

Is there a way in JavaScript to check if a string is a URL?

RegExes are excluded because the URL is most likely written like `stackoverflow`; that is to say that it might not have a `.com`, `www` or `http`.

Check if a JavaScript string is a URL

I want to add GET parameters to URLs that may and may not contain GET parameters without repeating `?` or `&amp;`.

Example:

If I want to add `category=action`

    $url=&quot;http://www.acme.com&quot;;
     // will add ?category=action at the end

    $url=&quot;http://www.acme.com/movies?sort=popular&quot;;
     // will add &amp;category=action at the end

If you notice I&#39;m trying to not repeat the question mark if it&#39;s found.

The URL is just a string.

GET URL parameter in PHP

I am receiving the rather self explanatory error:

&gt;A potentially dangerous Request.Path value was detected from the client (*).

The issue is due to `*` in the request URL:

    https://stackoverflow.com/Search/test*/0/1/10/1

This url is used to populate a search page where &#39;test*&#39; is the search term and the rest of the url relates to various other filters.

Is there an easy way to allow these special characters in the URL? I&#39;ve tried modifying the `web.config`, to no avail.

Should I manually encode / decode the special characters?
Or is there a best practice for doing this, I would like to avoid using query strings. - but it may be an option.

The application itself is a `c# asp.net` webforms application that uses routing to produce the nice URL above.

I am currently trying to get started with Akka and I am facing a weird problem. I&#39;ve got the following code for my Actor:

    class AkkaWorkerFT extends Actor {
      def receive = {
        case Work(n, c) if n &lt; 0 =&gt; throw new Exception(&quot;Negative number&quot;)
        case Work(n, c) =&gt; self reply n.isProbablePrime(c);
      }
    }

And this is how I start my workers:

    val workers = Vector.fill(nrOfWorkers)(actorOf[AkkaWorkerFT].start());
    val router = Routing.loadBalancerActor(SmallestMailboxFirstIterator(workers)).start()

And this is how I shut everything down:

    futures.foreach( _.await )
    router ! Broadcast(PoisonPill)
    router ! PoisonPill

Now what happens is if I send the workers messages with n &gt; 0 (no exception is thrown), everything works fine and the application shuts down properly. However, as soon as I send it a single message which results in an exception, the application does not terminate because there is still an actor running, but I can&#39;t figure out where it comes from.

In case it helps, this is the stack of the thread in question:

      Thread [akka:event-driven:dispatcher:event:handler-6] (Suspended)	
    	Unsafe.park(boolean, long) line: not available [native method]	
    	LockSupport.park(Object) line: 158	
    	AbstractQueuedSynchronizer$ConditionObject.await() line: 1987	
    	LinkedBlockingQueue&lt;E&gt;.take() line: 399	
    	ThreadPoolExecutor.getTask() line: 947

    	MonitorableThread(Thread).run() line: 680	
    	MonitorableThread.run() line: 182	

PS: The thread which is not terminating isn&#39;t any of the worker threads, because I&#39;ve added a postStop callback, every one of them stops properly.

PPS: `Actors.registry.shutdownAll` workarounds the problem, but I think shutdownAll should only be used as a last resort, shouldn&#39;t it?

Akka Actor not terminating if an exception is thrown

I&#39;m using Devise in a Rails 3 app, but in this case, a user must be created by an existing user, who determines what permissions he/she will have.

Because of this, I want:

- To **remove the route for users to sign up**. 
- To **still allow users to edit their profiles** (change email address and password) **after** they have signed up

How can I do this?

Currently, I&#39;m effectively removing this route by placing the following before `devise_for :users`:

    match &#39;users/sign_up&#39; =&gt; redirect(&#39;/404.html&#39;)

That works, but I imagine there&#39;s a better way, right?

## Update


As Benoit Garret said, the best solution in my case is to skip creating the registrations routes en masse and just create the ones I actually want. 

To do that, I first ran `rake routes`, then used the output to re-create the ones I wanted. The end result was this:

    devise_for :users, :skip =&gt; [:registrations] 
    as :user do
      get &#39;users/edit&#39; =&gt; &#39;devise/registrations#edit&#39;, :as =&gt; &#39;edit_user_registration&#39;
      put &#39;users&#39; =&gt; &#39;devise/registrations#update&#39;, :as =&gt; &#39;user_registration&#39;
    end

Note that:

- I still have `:registerable` in my `User` model
- `devise/registrations` handles updating email and password
- Updating other user attributes - permissions, etc - is handled by a different controller

## Actual answer:

Remove the route for the default Devise paths; i.e.:

    devise_for :users, path_names: {
      sign_up: &#39;&#39;
    }


How do I remove the Devise route to sign up?

I&#39;m working with Symfony 2 on a site which having 2 languages,
and I want to change patterns of my routes depending on user locale language !

Example:

    user_login_en:
        pattern:  /en/user/login.html
        defaults: { _controller: SfErrorsAppBundle:User:login, _locale: en }
    
    user_login_fr:
        pattern:  /fr/utilisateur/connexion.html
        defaults: { _controller: SfErrorsAppBundle:User:login, _locale: fr}


Inside a template, this is not difficult, i just have to pass the $this-&gt;get(&#39;session&#39;)-&gt;getLocale() from the controller to the template...

To work, I have to call my routes:

    $router-&gt;generate(&#39;user_login_&#39;.$locale, array());

But  inside my layouts, I have of course a menu, and sidebars, which have links... So I want to get the locale variable to use it ! So my question is simple: how to get this variable inside a &quot;layout&quot; template ? Otherwise, have you got any idea to change the pattern depending on the language ?

The reasons are that I want beautiful routes for all users, whether they&#39;re english or french... And also for a SEO reason !

How to get the _locale variable inside in a Symfony layout?

How do I get the current route in [Symfony][1] 2?
