• Setting Rails Checkbox from Another Model

  - by Kevin

  I have a checkbox that belongs to "Foo" class. I have another "Preferences" class that sets the default for what that checkbox should be. I tried using f.check_box :email_preference, :value => preferences.email_preference but it doesn't work. I use this page to do new record creation as well as edit, so obviously for new records I would want to take the preferences.email_preference setting as a default, then for editing the record use the foo.email_preference. Any suggestions?

• How do you protect your <appid>.appspot.com domain from DDOS attack?

  - by jacob

  If I want to use CloudFlare to help protect my GAE app via it's custom domain, I still am vulnerable to attacks directly on the .appspot.com domain. How do I mitigate that? I could force redirect appspot.com host requests, such as discussed here: http://stackoverflow.com/questions/1364733/block-requests-from-appspot-com-and-force-custom-domain-in-google-app-engine/ But I would still suffer the load of processing the redirect in my app. Are there any other solutions?

• Using scope, defined in parent model, inside it's child (STI pattern)

  - by Anton

  I implement a class hierarchy using STI pattern class A scope :aaa, where([someField]:[someValue]) end class B < A end The problem is that when I try to call something like: B.limit(5).aaa => SELECT "[table]".* FROM "[table]" WHERE "[table]"."type" IN ('A') AND ([someField] = [someValue]) LIMIT 5 So I am getting 5 objects of type A, which satisfies scope :aaa But I need to do the same with rows where type = "B" Is there any way to use scopes from parent, without redifinning it in childs in STI pattern? Thanks in advance EDITED I just discussed it with my frind and he showed me one important thing. A in not the root class of STI. IN fact whole hierarchy looks like class O < ActiveRecord::Base end class A < O scope ..... ..... end class B < A end maybe the reason is in hierarchy itself?...

• Logformat for catching asked hostname in a *.domain.com scenario?

  - by Dhiraj Gupta

  I have an Apache 2.2 VirtualHost with a *.domain.com Servername. This is required for my scenario, all subdomains are handled with the same site. Now, in the access log, I am trying to figure out a logformat variable (or way) that will let me log the asked for domain name. If I use the vhost_combined format, all I get in my access log is *.domain.com entries, not the actual vhost that was asked for. Anyone know how to do this?

• cross domain gwt ?

  - by jlo

  is there a way to run gwt on a proxy loaded web page ? ex) using proxy script on myexamplesite.com that loads finance.google.com, and running GWT on the newly loaded page. I've been doing the above before I found about GWT, using LAMP stack + Jquery (UI), which quickly turned out to be crap and inefficient. All this trouble to bypass browser's default Single Origin Policy. So, right now, is it possible to overcome this problem with GWT ? Is it possible to some how, run javascript on a html page from finance.google.com loaded into myexamplesite.com's frame with GWT or other solution? I am not looking to do JSON or RSS related topics. What I need is high lighted in bold. Is GWT + Gears what I should be using ? Thank you.

• Where to include business logic in a domain driven architecture

  - by Mike C.

  I'm trying to learn effective DDD practices as I go, but had a fundamental question I wanted to get some clarity on. I am using ASP.NET WebForms and I am creating a situation where a user places an order. Upon order submission, the code-behind retrieves the user, builds the order from the inputs on the form, calls the User.PlaceOrder() method to perform add the order object to the user's order collection, and calls the repository to save the record to the database. That is fairly simply and straightforward. Now I need to add logic to send an order confirmation email, and I'm not really sure the proper place to put this code or where to call it. In the olden days I would simply put that code in the code-behind and call it at the same time I was building the order, but I want to get a step closer to solid proper architecture so I wanted to get some information. Thanks for your help!

• WordPress > microsites use main site's menu (same domain, multiple subdirectories, multiple WP insta

  - by Scott B

  I have a main site at site.com and several subdirectory "microsites" at site1.site.com, site2.site.com, etc. These are all on the same server. Each site is set up in its own folder under public_html and each with its own separate wordpress install. I'd like for each microsite to share the same top level menu (the page's menu) with the main site. I'm sure there are several approaches and I'd like to ask you for a few ideas. As an aside, I'd also like to ask if the new WordPress 3.0 beta would make this simpler to do (since it combines wordpress MU into the main wordpress core)

• Programatically adding,changing and removing controls bound to model objects (MVVM)

  - by Ittai

  I have the following scenario and I'm trying to decide how it can and should be implemented in silverlight and c# via MVVM. Scenario: I have the following objects in my scenario: MyModel, MyModelControl, MyView and MyViewModel. MyModelcontrol is a custom UserControl of mine and the rest I think are pretty much self explanatory. MyViewModel is a Subscriber of a message which hands it a Collection<MyModel> newCol and let's mark curCol as the current Collection<MyModel> that MyViewModel holds. I then want to programatically add MyModelControl controls for each MyModel instance which belongs to newCol and not to curCol. I also want to bind the MyModelControl instance to the corresponding MyModel instance. In a similar manner I want to remove the controls which don't belong now to the collection and I want to update a property for those which belong to both. I do not want to remove all controls which belong to curCol and then add all controls for newCol as the creation of MyModelControl is "expensive". I'd appreciate help with how this should be implemented in SL as I'm new to it and to the MVVM pattern. Comments regarding the design would also be welcomed. B.T.W This will run on Windows Phone 7 so I think there are some limitations on versions, if this is an issue please comment and I'll verify which versions exactly I can use on the phone.

• Update model objects across different activities

  - by Tom Esterez

  Lets say I have 2 activities: A: A ListView displaying articles titles. Data is fetched from a web server and converted from XML to a list of ArticleSummary. Only user titles and id are returned by the server. Click on a title starts activity B. B: A form to edit an article. Article is fetched from server. When the user hits OK, modifications are sent to the server and activity closed. When the user go back to activity A, I would like to update the article title without any additional web request. I was thinking about the following solution: When article is modified, send a broadcast event with article id and new attributes values. Listen for this event on activity A Update the ArticleSummary object notify data changed on ListView Is there a better approach ?

• how to create a auto-incremented attribute in xcode managed object model

  - by Mausimo

  Hey, what i want to do is to make a int that will be the ID of the entity and auto increment itself whenever a new entity is added (just like a SQL identity property). Is this possible? i tried using indexed (checked on attribute) however there is no description to what indexed even does. EDIT: I am adding annotations to a map, when you click the pin the annotationview with a chevron shows up. Now when you click this button i would like to load an associated picture. However the only way i know how to link the picture to this button is to give the picture a unique id, and then set the button.tag to this id and then load based on the button.tag.

• How to create a local user with the same name as a likewise domain user?

  - by JamesRyan

  I need to create a local user with the same name as a domain user under CentOS with Likewise installed. When I use Useradd it says user exists, because a domain user with the same name exists. It is a service account for backup and does not work using a domain account. On machines where the local account was added before likewise was installed it works fine. Is there a way to temporarily disable this check?

• What is the best way to migrate to a new file share in a new domain?

  - by cbattlegear

  I am looking to move a file share (100 GB or so) from one domain/server to a new domain and server. I would like to do this with little to no downtime and if possible I would like to be able to map permissions from the groups/users in the current system to groups/users in the new domain. A side question, a large number of the files in the system are office documents with hard links to the old file server. Any way to programmatically change all those links to the new file server?

I need to redirect the app to the same page and flash the error. How do i do this? I have overridden the method in my own user.rb so that I can change the code.

  in my asp.net MVC project i have an database connection with connectionstring: Data Source=.;Initial Catalog=dbname;Integrated Security=True All users can execute Stored Procedures on that connection and i want to log those users. so after each execution I store "User.Identity.Name" to another database.

• MVC + Repository Pattern - Still depends on Data Model?

  - by Jack

  I've started a project for school in which I am using ASP.NET MVC 2 + LINQ2SQL, and a business layer so my UI doesnt interact with the DB directly. My question is this: In my MVC project, when bringing up views and passing around data, I still have to include my Data project for access to the classes in my Linq2Sql project. Is this correct? Example: Controller: ClassesRepository cr = new ClassesRepository(); // this is from my Business project Class classToEdit = cr.GetByClassId(id); // "Class" is from my data project I still have to reference the Class class in my linq2sql data project - shouldn't my UI be completely independent of my data layer? Or maybe I'm going about this all wrong.

• Cross domain XMLHttpRequest in classic ASP

  - by HahaHehe

  My code is working fine till i migrate it to another server with firewall. After since, some part of my code is not working. Its seem to be the xmlhttp POST problem. Can someone point me to the right direction and how to determine if the firewall is the problem. My client insisted to me to use classic asp, so i cannot upgrade to .net. Dim objHttp SUBMIT_URL = "http://www.abc.com/confirm.asp" Call Process() Public Sub Process() set objHttp = Server.CreateObject("Microsoft.XMLHTTP") 'set the timeout values in milliseconds lResolve = 1 * 1000 lConnect = 1 * 1000 lSend = 2 * 1000 lReceive = 2 * 1000 objHttp.open "POST", SUBMIT_URL, false objHttp.setRequestHeader "Content-type", "application/x-www-form-urlencoded" objHttp.Send str if err.number <> 0 then Response.Write "Error : " & err.Description err.Clear end if End Sub

• ASP.NET MVC Access model data in masterpage

  - by Paul

  I have created a UserSiteBaseController that gets commonly used data and sets the data to a UserSiteBaseViewData viewmodel in a method called SetViewData public T CreateViewData<T>() where T : UserSiteBaseViewData, new() { .... } I then create specific Controllers that inherit from the UserSiteBaseController as well as viewModels that inherit from UserSiteHomeViewData and can be created in the controller like so: public ActionResult Index(string slug) { Slug = slug; var viewData = CreateUserSiteHomeViewData<UserSiteHomeViewData>(); //If invalid slug - throw 404 not found if (viewData == null) return PageNotFound(); viewData.Announcements = _announcementsData.All(slug).ToList(); return View(viewData); } private T CreateUserSiteHomeViewData<T>() where T : UserSiteHomeViewData, new() { T viewData = CreateViewData<T>(); return viewData; } The UserBaseViewData holds data that needs to be use on every page so it would be great to be able to access this data from the Masterpage in a strongly typed manner. Is this possible or am I going about this in the incorrect manner?
