To run a command 5 times in a row, you can do

    5.times { send_sms_to(&quot;xxx&quot;) }

For more info, see the [`times` documentation](http://www.ruby-doc.org/core/classes/Integer.html#M000187) and there&#39;s also the [`times` section](http://www.techotopia.com/index.php/Looping_with_for_and_the_Ruby_Looping_Methods#The_Ruby_times_Method) of [Ruby Essentials](http://www.techotopia.com/index.php/Ruby_Essentials)

You can use the [`times`](https://ruby-doc.org/core-1.9.3/Integer.html#method-i-times) method of the class `Integer`:

    5.times do 
       send_sms_to(&#39;xxx&#39;) 
    end

or a `for` loop

    for i in 1..5 do
      send_sms_to(&#39;xxx&#39;)
    end

or even a `upto`/`downto`:

    1.upto(5) { send_sms_to(&#39;xxx&#39;) }

Here is an example using ranges:

    (1..5).each { send_sms_to(&quot;xxx&quot;) }

Note: [ranges](http://ruby-doc.org/core-2.1.3/Range.html) constructed using `..` run from the beginning to the end inclusively.

I only use terminal (mac) for git, and I only use git for one directory. Is it possible to set the default directory (the directory when terminal is opened) to the directory where I use git, and if so how?

    @NotAudited
    @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
    @OneToMany(mappedBy = &quot;booking&quot;)
    @OrderBy(&quot;bookingOrder&quot;)
    private List&lt;CustomerBooking&gt; customerBookingList = new LinkedList&lt;CustomerBooking&gt;();

Why use both? is it good to use both or would one suffice?

I&#39;ve tried Cucumber for a few projects a couple of years ago and am looking to give it another go. I don&#39;t really need another &quot;Beginning Cucumber&quot; article. Instead, I&#39;d like to see some actual uses in the wild—one&#39;s that other Cucumber users would consider idiomatic and antipattern-free.

So, in your opinion, what are the best examples of actual Cucumber specs in large projects?

Good Cucumber examples in the wild?

Is there any way to create a variable in a module in Ruby that would behave similar to a class variable? What I mean by this is that it would be able to be accessed without initializing an instance of the module, but it can be changed (unlike constants in modules).

I am confused with the usage of `||=` operator in Rails. I couldn&#39;t locate anything useful on the web. Can anyone please guide me?

Do let me know if there are any weblinks that you are aware of.

I would like what the following statement means:

    @_current_user ||= session[:current_user_id] &amp;&amp;
          User.find(session[:current_user_id])


When do we use the &quot;||=&quot; operator in Rails ? What is its significance?

in my rails app I&#39;m creating an array like so:

    @messages.each do |message|

      @list &lt;&lt; {
        :id =&gt; message.id,
        :title =&gt; message.title,
        :time_ago =&gt; message.replies.first.created_at
      }
    end

After making this array I would like to then sort it by time_ago ASC order, is that possible?

Is there a nice (one line) way of writing a hash in ruby with some entry only there if a condition is fulfilled? I thought of

    {:a =&gt; &#39;a&#39;, :b =&gt; (&#39;b&#39; if condition)}

But that leaves `:b == nil` if the condition is not fulfilled. I realize this could be done easily in two lines or so, but it would be much nicer in one line (e.g. when passing the hash to a function).

Am I missing (yet) another one of ruby&#39;s amazing features here? ;)

Build-in rake tasks work fine, but my new custom one, in Project/lib/tasks/payments.rb doesn&#39;t get loaded:

    namespace :payments  do
      desc &quot;Tally payments at the end of the month&quot;
      task :compute =&gt; :environment do
        BillingPeriod.compute_new_period
      end
    end

    $ rake payments:compute
    (in /Users/rob/Code/Apps/skyfarm)
    rake aborted!
    Don&#39;t know how to build task &#39;payments:compute&#39;

It works fine if I load the file application.rb:

    require &#39;lib/tasks/payments.rb&#39;

...but it breaks other things:

    $ rails s
    ./lib/tasks/payments.rb:1: undefined method `namespace&#39; for main:Object (NoMethodError)




Why is my custom rake task in lib/tasks not discovered in Rails 3?

I have a model A that has a &quot;has_many&quot; association to another model B.  I have a business requirement that an insert into A requires at least 1 associated record to B.  Is there a method I can call to make sure this is true, or do I need to write a custom validation?

Right now I&#39;m using this which works for the development host, but I have to manually change the {:host =&gt; &quot;&quot;} code when I move to production.

### post.rb

    def share_all
      url =  Rails.application.routes.url_helpers.post_url(self, :host =&gt; &#39;localhost:3000&#39;)
      if user.authentications.where(:provider =&gt; &#39;twitter&#39;).any?
        user.twitter_share(url)  
      end
    end

I&#39;d like to use this and then define the default_url_options per environment:

### post.rb

    def share_all
      url =  Rails.application.routes.url_helpers.post_url(self)
      if user.authentications.where(:provider =&gt; &#39;twitter&#39;).any?
        user.twitter_share(url)  
      end
    end


I&#39;ve tried adding this to my config/environments/development.rb but I still get the &quot;Missing host to link to! Please provide :host parameter or set default_url_options[:host]&quot; error 

### development.rb

    config.action_controller.default_url_options = {:host =&gt; &quot;localhost:3000&quot;}


And I even tried it this way:

### development.rb 
    config.action_controller.default_url_options = {:host =&gt; &quot;localhost&quot;, :port =&gt; &quot;3000&quot;}



EDIT:

I&#39;ve now also followed this and still the same error guide http://edgeguides.rubyonrails.org/action_controller_overview.html#default_url_options

### application controller

    class ApplicationController &lt; ActionController::Base
      protect_from_forgery
      include ApplicationHelper
      def default_url_options
        if Rails.env.production?
          { :host =&gt; &quot;example.com&quot;}
        else
          {:host =&gt; &quot;example1.com&quot;}
        end
      end
    end

This is driving me crazy, what am I missing here???

How to set config.action_controller.default_url_options = {:host = &#39;#&#39;&#39;} on per environment basis

image_tag isn&#39;t using the asset_host I&#39;ve set. Any ideas why? The only thing I can think of is it having to do with it being a Mailer.


**config/environment/development.rb**

    config.action_controller.asset_host = &quot;http://localhost:3000&quot;

  
**myMailer.rb**

    &lt;%= image_tag &quot;logo.png&quot;, :style=&gt;&quot;margin-left:10px; padding-bottom:15px;&quot; %&gt;

**rendered as:**
 
    &lt;img alt=&quot;Logo&quot; src=&quot;/images/logo.png?1303090162&quot; style=&quot;margin-left:10px; padding-bottom:15px;&quot; /&gt;

**In console:**
   
    &gt; MyApp::Application.config.action_controller
    #&lt;OrderedHash {… :asset_host=&gt;&quot;http://localhost:3000&quot;, …}&gt;

I need the image_tag to create a full path url because it will be showing up in an email.
