You can also do it like this:

    Delayed::Worker.new.run( Delayed::Job.find(x) ) 



answering how to run specific job from console:

```Delayed::Job.find(x).invoke_job```

but you must remember that it won&#39;t run any other things like destroying job that was done or so on. just running the job/task.

On Heroku I had a &quot;stuck&quot; job and just had to run `heroku restart` for the worker/job to start again.

I have the following class:

    class Detail
    {
        public Detail()
        {
            _details = new List&lt;string&gt;();
        }
        public IList&lt;string&gt; Details { get { return _details; } }
        private readonly List&lt;string&gt; _details;
    }

Currently I sort the class randomly using the following:

    void ShuffleGenericList&lt;T&gt;(IList&lt;T&gt; list)
    {
        //generate a Random instance
        var rnd = new Random();
        //get the count of items in the list
        var i = list.Count();
        //do we have a reference type or a value type
        T val = default(T);

        //we will loop through the list backwards
        while (i &gt;= 1)
        {
            //decrement our counter
            i--;
            //grab the next random item from the list
            var nextIndex = rnd.Next(i, list.Count());
            val = list[nextIndex];
            //start swapping values
            list[nextIndex] = list[i];
            list[i] = val;
        }
    }

What I would like to do is to sort the contents of details in alphabetic order.

So for example if the contents look like this:

    [0] a
    [1] d
    [2] b

I want to be able to run this method and have them sorted into:

    [0] a
    [1] b
    [2] d

Does anyone know of a simple way to do this? Note that the lists usually have less than ten entries in them. Can I do this with LINQ? Sorry but I am not very familiar with LINQ I have just heard a suggestion that I could use that.

I am presently working on an WiFi application for Android. I am having trouble trying to access the database on the device. Debugging in the emulator doesn&#39;t work for me, because there is no WiFi support in the emulator. I tried pulling the database file out of the device by using 

    adb pull data/data/package-name/databases/database-name


But I get the error &quot;Permission denied.&quot;. 
In this answer https://stackoverflow.com/questions/1105219/android-where-are-database-files-stored/1106563#1106563, Commonsware has suggested to pull database file by running in debug mode. But it doesn&#39;t work too. Any help on how to debug the database without rooting the device would be much appreciated.

For some reason, Delayed::Job&#39;s has decided to queue up but not excecute anything even though I&#39;ve restarted it several times, even kill -9&#39;d it and restarted it. It won&#39;t run any jobs.

Can I , in /console, specify a specific job and tell it to work?

Ex:.. `Delayed::Job.find(x).run`

How do you tell a specific Delayed::Job to run in console?

What would the difference be?

Example Match:&lt;br/&gt;
`match &#39;photos/show&#39; =&gt; &#39;photos#show&#39;`

Example Get:&lt;br/&gt;
`get &#39;photos/show&#39;`

Wouldn&#39;t both make it possible to reach the photos/show URL and also use the show action in the photos controller?

Thanks

Ruby on Rails Routes - difference between get and match

A `Person` can have many `Events` and each `Event` can have one polymorphic `Eventable` record.  How do I specify the relationship between the `Person` and the `Eventable` record?

Here are the models I have:

    class Event &lt; ActiveRecord::Base
      belongs_to :person
      belongs_to :eventable, :polymorphic =&gt; true
    end
    
    class Meal &lt; ActiveRecord::Base
      has_one :event, :as =&gt; eventable
    end
   
    class Workout &lt; ActiveRecord::Base
      has_one :event, :as =&gt; eventable
    end

The main question concerns the `Person` class:

    class Person &lt; ActiveRecord::Base
      has_many :events
      has_many :eventables, :through =&gt; :events  # is this correct???
    end

Do I say `has_many :eventables, :through =&gt; :events` like I did above?

Or do I have to spell them all out like so:

    has_many :meals, :through =&gt; :events
    has_many :workouts, :through =&gt; :events

If you see an easier way to accomplish what I&#39;m after, I&#39;m all ears! :-)


Rails: has_many through with polymorphic association - will this work?

Using this modified example from [the Rails guides][1], how does one model a relational &quot;has_many :through&quot; association using mongoid?

The challenge is that mongoid does not support has_many :through as ActiveRecord does.

    # doctor checking out patient
    class Physician &lt; ActiveRecord::Base
      has_many :appointments
      has_many :patients, :through =&gt; :appointments
      has_many :meeting_notes, :through =&gt; :appointments
    end
    
    # notes taken during the appointment
    class MeetingNote &lt; ActiveRecord::Base
      has_many :appointments
      has_many :patients, :through =&gt; :appointments
      has_many :physicians, :through =&gt; :appointments
    end
    
    # the patient
    class Patient &lt; ActiveRecord::Base
      has_many :appointments
      has_many :physicians, :through =&gt; :appointments
      has_many :meeting_notes, :through =&gt; :appointments
    end
     
    # the appointment
    class Appointment &lt; ActiveRecord::Base
      belongs_to :physician
      belongs_to :patient
      belongs_to :meeting_note
      # has timestamp attribute
    end

I am currently working on a Rails 3 project that is divided up into four parts:

 - The public facing website
 - The administration website/backend
 - The models
 - The API for third party data access

As the models are shared between the three key components I want to keep them away from being in one main project, however each part needs access to the models, but I don&#39;t want to repeat the code and have different versions everywhere.

Currently I have the model code in a gem, and in each project&#39;s Gemfile I am referencing them with the following line:

    gem &quot;my_models&quot;, :path =&gt; &quot;../my_models/&quot;

However when I deploy to our test servers for my co-workers to evaluate the system on I need to pull the models from an external repository, so I swap out the above line with the following:

    gem &quot;my_models&quot;, :git =&gt; &quot;git@private.repository.com:username/my_models.git&quot;

This in its self works well, but its quite clunky in terms of &#39;versions&#39; (i.e. I need to bump the version every time I wish to deploy the changes to the test servers), switch the line over to use git instead of local, and make sure that I&#39;m pushing the files properly.

Previously I was using a shared git submodule, but this was just as awkward.

I would rather not build everything into one mega-project, as these tend to become monstrous and difficult to maintain, and I would also like to separate concerns if possible, so any changes I make to the administration site doesn&#39;t have much of a chance to impact the other components - obviously the models have the potential to cause issues, but that is a risk I have considered and understand.

What would people out there suggest when it comes to something like this? Or, am I going about it completely the wrong way?

*Some additional background:*

This app is a rewrite of an existing website which followed the model of &#39;lump everything into the one project&#39; - unfortunately there are two issues here:

 1. The app was badly developed - I inherited this project and when I first picked it up the load times were ~2 minutes per page with a single user - this has since been reduced but still has issues throughout
 2. We are currently at our capacity limit of the current site and we anticipate that we will need to take on more load in the next 6 months - however scaling out with an &#39;all in one&#39; app means we&#39;ll be wasting resources on scaling out the back end of the site which doesn&#39;t need it.

Essentially there are two things I want to separate - the Front end (being the public website and the API) and the back end - everything I know about software development tells me that combining all this together is not an ideal solution (and past history shows me that splitting these two is a good move in terms of ensuring front end performance).

Perhaps I need to look at this from another angle - keep the models in each project, and instead of sharing them between projects have a cut-down subset of functionality for each functional area (i.e. the backend needs to know who created a post, but the front end doesn&#39;t really care about that, so omit that logic when reading in the model).

Shared models between two Rails apps - what is the ideal solution for Workflow?

I wonder if I succeeded to get [Delayed::Job](https://github.com/collectiveidea/delayed_job) working.
Can&#39;t see jobs in the `delayed_jobs` table.

- Is that normal?
- Is there any other ways too see job queue?

How can I see the delayed job queue?

trying to upgrade to Rails 4.2, using delayed_job_active_record. I&#39;ve not set the delayed_job backend for test environment as thought that way jobs would execute straight away. 

I&#39;m trying to test the new &#39;deliver_later&#39; method with RSpec, but I&#39;m not sure how.

Old controller code:

    ServiceMailer.delay.new_user(@user)

New controller code:

    ServiceMailer.new_user(@user).deliver_later

I USED to test it like so:

    expect(ServiceMailer).to receive(:new_user).with(@user).and_return(double(&quot;mailer&quot;, :deliver =&gt; true))

Now I get errors using that. (Double &quot;mailer&quot; received unexpected message :deliver_later with (no args))

Just

    expect(ServiceMailer).to receive(:new_user)

fails too with &#39;undefined method `deliver_later&#39; for nil:NilClass&#39;

I&#39;ve tried some examples that allow you to see if jobs are enqueued using test_helper in ActiveJob but I haven&#39;t managed to test that the correct job is queued.

    expect(enqueued_jobs.size).to eq(1)

This passes if the test_helper is included, but it doesn&#39;t allow me to check it is the correct email that is being sent.

What I want to do is:

 - test that the correct email is queued (or executed straight away in test env)
 - with the correct parameters (@user)

Any ideas??
thanks
