• Resource mapping in a Ruby on Rails URL (RESTful API)

  - by randombits

  I'm having a bit of difficulty coming up with the right answer to this, so I will solicit my problem here. I'm working on a RESTFul API. Naturally, I have multiple resources, some of which consist of parent to child relationships, some of which are stand alone resources. Where I'm having a bit of difficulty is figuring out how to make things easier for the folks who will be building clients against my API. The situation is this. Hypothetically I have a 'Street' resource. Each street has multiple homes. So Street :has_many to Homes and Homes :belongs_to Street. If a user wants to request an HTTP GET on a specific home resource, the following should work: http://mymap/streets/5/homes/10 That allows a user to get information for a home with the id 10. Straight forward. My question is, am I breaking the rules of the book by giving the user access to: http://mymap/homes/10 Technically that home resource exists on its own without the street. It makes sense that it exists as its own entity without an encapsulating street, even though business logic says otherwise. What's the best way to handle this?

• URL Mapping prefix in Grails

  - by Furuno

  Recently, I'm trying to migrating my application from CakePHP to Grails. So far it's been a smooth sailing, everything I can do with CakePHP, I can do it with much less code in Grails. However, I have one question : In CakePHP, there's an URL Prefix feature that enables you to give prefix to a certain action url, for example, if I have these actions in my controller : PostController admin_add admin_edit admin_delete I can simply access it from the URL : mysite/admin/post/add mysite/admin/post/edit/1 mysite/admin/post/delete/2 instead of: mysite/post/admin_add mysite/post/admin_edit/1 mysite/post/admin_delete/2 Is there anyway to do this in Grails, or at least alternative of doing this?

• Path of Replication

  - by geeko

  I'm currently developing a replication system to keep data in-synch between an arbitrary number of servers. Some of these servers exist in one cluster on one LAN. Others exist somewhere else in the world. I'm wondering what are the pros/cons of different paths that we choose to flow replicated data on between servers? In other words, what are the different strategies to load balance the replication process ?

• Set and Verify the Retention Value for Change Data Capture

  - by AllenMWhite

  Last summer I set up Change Data Capture for a client to track changes to their application database to apply those changes to their data warehouse. The client had some issues a short while back and felt they needed to increase the retention period from the default 3 days to 5 days. I ran this query to make that change: sp_cdc_change_job @job_type='cleanup', @retention=7200 The value 7200 represents the number of minutes in a period of 5 days. All was well, but they recently asked how they can verify...(read more)

• Best practice? - Array/Dictionary as a Core Data Entity Attribute

  - by Run Loop

  I am new to Core Data. I have noticed that collection types are not available as attribute types and would like to know what the most efficient way is of storing array/dictionary type data as an attribute (e.g. the elements that make up an address like street, city, etc. does not require a separate entity and is more conveniently stored as a dictionary/array than separate attributes/fields). Thank you.

• Url mapping with my servlet?

  - by user291701

  Hi, I'm using GWT with GAE. When the user enters any of the following urls, I want to just serve my app as usual to them: http://www.mysite.com/ http://www.mysite.com/dog http://www.mysite.com/cat the first case works by default. I'm not sure how to get the /dog and /cat cases to work. I think I have to modify something with the url mappings to get that to work in web.xml. Essentially I'm trying to just get my app served with any url entered: http://www.mysite.com/* Thanks

• Rack URL Mapping

  - by Puru puru rin..

  Hi, I am trying to write two kind of Rack routes. Rack allow us to write such routes like so: app = Rack::URLMap.new('/test' => SimpleAdapter.new, '/files' => Rack::File.new('.')) In my case, I would like to handle those routes: "/" or "index" "/*" in order to match any other routes So I had trying this: app = Rack::URLMap.new('/index' => SimpleAdapter.new, '/' => Rack::File.new('./public')) This works well, but... I don't know how to add '/' path (as alternative of '/index' path). The path '/*' is not interpreted as a wildcard, according to my tests. Do you know how I could do? Thanks
