• Apache config that uses two document roots based on whether the requested resource exists in the first

  - by mattalexx

  Background I have a client site that consists of a CakePHP installation and a Magento installation: /web/example.com/ /web/example.com/app/ <== CakePHP /web/example.com/app/webroot/ <== DocumentRoot /web/example.com/app/webroot/store/ <== Magento /web/example.com/config/ <== Site-wide config /web/example.com/vendors/ <== Site-wide libraries The server runs Apache 2.2.3. The problem The whole company has FTP access and got used to clogging up the /web/example.com/, /web/example.com/app/webroot/, and /web/example.com/app/webroot/store/ directories with their own files. Sometimes these files need HTTP access and sometimes they don't. In any case, this mess makes my job harder when it comes to maintaining the site. Code merges, tarring the live code, etc, is very complicated and usually requires a bunch of filters. Abandoned solution At first, I thought I would set up a new subdomain on the same server, move all of their files there, and change their FTP chroot. But that wouldn't work for these reasons: Firstly, I have no idea (and neither do they remember) what marketing materials they've sent out that contain URLs to certain resources they've uploaded to the server, using the main domain, and also using abstract subdomains that use the main virtual host because it has ServerAlias *.example.com. So suddenly having them only use static.example.com isn't feasible. Secondly, The PHP scripts in their projects are potentially very non-portable. I want their files to stay in as similar an environment as they were built as I can. Also, I do not want to debug their code to make it portable. Half-baked solution After some thought, I decided to find a way to section off the actual website files into another directory that they would not touch. The company's uploaded files would stay where they were. This would ensure that I didn't break any of their projects that needed HTTP access. It would look something like this: /web/example.com/ <== A bunch of their files are in here /web/example.com/app/webroot/ <== 1st DocumentRoot; A bunch of their files are in here /web/example.com/app/webroot/store/ <== Some more are in here /web/example.com/site/ <== New dir; Contains only site files /web/example.com/site/app/ <== CakePHP /web/example.com/site/app/webroot/ <== 2nd DocumentRoot /web/example.com/site/app/webroot/store/ <== Magento /web/example.com/site/config/ <== Site-wide config /web/example.com/site/vendors/ <== Site-wide libraries After I made this change, I would not need to pay attention to anything except for the stuff within /web/example.com/site/ and my job would be a lot easier. I would be the only one changing stuff in there. So here's where the Apache magic would happen: I need an HTTP request to http://www.example.com/ to first use /web/example.com/app/webroot/ as the document root. If nothing is found (no miscellaneous uploaded company projects are found), try finding something within /web/example.com/site/app/webroot/. Another thing to keep in mind is, the site might have some problems if the $_SERVER['DOCUMENT_ROOT'] variable reads /web/example.com/app/webroot/ but the actual files are within /web/example.com/site/app/webroot/. It would be better if the DOCUMENT_ROOT environment variable could be /web/example.com/site/app/webroot/ for anything within the /web/example.com/site/app/webroot/ directory. Conclusion Is my half-baked solution possible with Apache 2.2.3? Is there a better way to solve this problem?

• What is the best resource or method for learning more about servers and networking?

  - by kaleidomedallion

  I can get around a server to some degree, but everything I have learned has been as I have needed to learn it. Every once in a while I will learn about some new command that will revolutionize how I think about systems and networking, and realize how I could have been using it this whole time if only I had known about it. Anything to bring someone from novice to some kind of fluency? Do I just need to earn the battle scars bit by bit over the course of years? (I mean of course I do but what can I do to help it be not quite so painful?) For instance, I am still fuzzy on all of networking. Any help would be greatly appreciated.

• How does 301 redirection work across the network? & should I use it if there is a chance we made need to change the resource back to the original URL?

  - by Faust

  I've built a CMS that makes it fairly easy for my client to relocate pages in their site hierarchy. This site has all human-readable and intuitive URLs, so moving a page necessarily means that its URL changes. I am storing records of each resource's past URLs in the data store so that requests for bygone URLs are re-routed to their appropriate successors. I'm warning my clients not to re-arrange the site willy-nilly (for numerous reasons). But nevertheless I suspect there's a chance page moves could get reversed from time to time. So I'm trying to figure out whether 301 or 302 or 307 redirects should be used when serving up pages to requests for out-of-date URLs. I understand the value of using 301 for search engine optimization. But my concern is with this system possibly inadvertently making some pages unavailable to some users QUESTIONS: That is, if the clients move a page at location/URL A to a new location B, then users get the redirect for A to B, and then the clients move the page back to A again, how long can I expect any of those users to keep getting their requests for A redirected to B -- in this case sending them to my friendly 404 page? Is it until an item in their browser history is cleared? Is the redirect somehow cached in routers throughout the internet? How does this work? How long can I expect the 301 redirect to linger out there ?

• Is there a way to use VirtualBox without using it's resource registry?

  - by Catskul

  Summary VirtualBox seems to want everything to be "registered" which makes it much more annoying to work with on the command line. I'm attempting to create an automated script which will create, move, start, stop, and destroy virtual machines and virtual disks. Requiring registration will complicate the task for the following reasons. leaves state information around that can cause unpredicted edgecases causing scripts to fail. creates potential name space collisions for multiple process creating VMs with the same name moving/copying resources on the same machine is more complicated because references in the registry need to be updated copying resources (disk + vm combination) to another machine require reconfiguration once they reach their target machine, and require the transfer of extra meta data to do the reconfiguration. If something unexpectedly fails, and an unregister thus fails to happen, left over configuration information can cause problems in subsequent runs. Use Case My specific use case is for a continuous integration server which creates and destroys VMs and Disk images potentially with the same name, and would require more logic to deal with the registry's statefulness. Imaginary Example It seems that I should just be able to for example (using some imaginary and/or incorrect commands): mkdir foobar customdiskimg_script ./foo/foo.vdi vboxmanage createvm --name "foo" --ostype Linux --basefolder ./foo/foo.xml vboxmanage storagectl ./foo/foo.xml --name foo --add ide vboxmanage storageattach --storagectl foo --medium ./foo/foo.vdi ./foo/foo.xml vboxmanage startvm ./foo/foo.xml TLDR Is there a way to use virtualbox without "registering" harddisks and VMs?

• Can someone please explain these Network Activity entries are? (resource monitor windows 7)

  - by Keyes

  The first one is the address microsoftword.com.br. What is this? I noticed when I connected windows to the internet briefly, and it went away soon after. when I typed the address into my tablet, it redirected to bing with the search "microsoftword com" with MSSRPD at the end of the address. The other unknowns seemed to appear when my brothers laptop was connected to the network. Is that normal? Usually if I disconnected and reconnected they would appear, but I noticed when I had disconnected and reconnected to try it didn't happen as he wasn't connected. I'm concerned about the microsoftword one is. Is it legitimate? The svchost that associated with is a legit svchost image.

• Error using eclipse for Android - No resource found that matches the given name.

  - by Kenny

  Common problem I'm sure, but I can't figure it out. In my AndroidManifest.xml and main.xml I'm getting the no resource found that matches the given name. I've double checked for typos and it used to work, but now I'm popping up with all these errors saying it can't find my strings in my strings.xml.

• When I use a form to call a method on the controller, I want the page to refresh, and the url to sho

  - by MedicineMan

  Using ASP MVC, I have set up a webpage for localhost/Dinner/100 to show the dinner details for dinner with ID = 100. On the page, there is a dropdown that shows Dinner 1, Dinner 2, etc. The user should select the dinner of interest (Dinner 2, ID = 102) off the form and press submit. The page should refresh and show the url: localhost/Dinner/102, and show the details of dinner 2. My code is working except for the url. During this, my url shows localhost/Dinner/100 even though it is correctly displaying the details of Dinner 2 (ID = 102). My controller method is pretty simple: public ActionResult Index(string id) { int Id = 0; if (!IsValidFacilityId(id) || !int.TryParse(id, out Id)) { return Redirect("/"); } return View(CreateViewModel(Id)); } can you help me figure out how to get this all working? p.s. I did create a custom route for the method: routes.MapRoute( "DinnerDefault", // Route name "Dinner/{id}", // URL with parameters new { controller = "Dinner", action = "Index", id = "" } // Parameter defaults );

• RESTful API design question - how should one allow users to create new resource instances?

  - by Tamás

  I'm working in a research group where we intend to publish implementations of some of the algorithms we develop on the web via a RESTful API. Most of these algorithms work on small to medium size datasets, and in many cases, a user of our services might want to run multiple queries (with different parameters) on the same dataset, so for me it seems reasonable to allow users to upload their datasets in advance and refer to them in their queries later. In this sense, a dataset could be a resource in my API, and an algorithm could be another. My question is: how should I let the users upload their own datasets? I cannot simply let users upload their data to /dataset/dataset_id as letting the users invent their own dataset_ids might result in ID collision and users overwriting each other's datasets by accident. (I believe one of the most frequently used dataset ID would be test). I think an ideal way would be to have a dedicated URL (like /dataset/upload) where users can POST their datasets and the response would contain a unique ID under which the dataset was stored, but I'm not sure that it does not violate the basic principles of REST. What is the preferred way of dealing with such scenarios?

• How do I access variable values from one view controller in another?

  - by Thomas

  Hello all, I have an integer variable (time) in one view controller whose value I need in another view controller. Here's the code: MediaMeterViewController // TRP - On Touch Down event, start the timer -(IBAction) startTimer { time = 0; // TRP - Start a timer timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(updateTimer) userInfo:nil repeats:YES]; [timer retain]; // TRP - Retain timer so it is not accidentally deallocated } // TRP - Method to update the timer display -(void)updateTimer { time++; // NSLog(@"Seconds: %i ", time); if (NUM_SECONDS == time) [timer invalidate]; } // TRP - On Touch Up Inside event, stop the timer, decide stress level, display results -(IBAction) btn_MediaMeterResults { [timer invalidate]; NSLog(@"Seconds: %i ", time); ResultsViewController *resultsView = [[ResultsViewController alloc] initWithNibName:@"ResultsViewController" bundle:nil]; [self.view addSubview:resultsView.view]; } And in ResultsViewController, I want to process time based on its value ResultsViewController - (void)viewDidLoad { if(time < 3) {// Do something} else if ((time > 3) && (time < 6)) {// Do something else} //etc... [super viewDidLoad]; } I'm kind of unclear on when @property and @synthesize is necessary. Is that the case in this situation? Any help would be greatly appreciated. Thanks! Thomas

• Where's the Win32 resource for the mouse cursor for dragging splitters?

  - by Luther Baker

  I am building a custom win32 control/widget and would like to change the cursor to a horizontal "splitter" symbol when hovering over a particular vertical line in the control. IE: I want to drag this vertical line (splitter bar) left and right (WEST and EAST). Of the the system cursors (OCR_*), the only cursor that makes sense is the OCR_SIZEWE. Unfortunately, that is the big, awkward cursor the system uses when resizing a window. Instead, I am looking for the cursor that is about 20 pixels tall and around 3 or 4 pixel wide with two small arrows pointing left and right. I can easily draw this and include it as a resource in my application but the cursor itself is so prevalent that I wanted to be sure it wasn't missing something. For example: when you use the COM drag and drop mechanism (CLSID_DragDropHelper, IDropTarget, etc) you implicitly have access to the "drag" icon (little box under the pointer). I didn't see an explicit OCR_* constant for this guy ... so likewise, if I can't find this splitter cursor outright, I am wondering if it is part of a COM object or something else in the win32 lib.

• Ruby on Rails: how to get error messages from a child resource displayed?

  - by randombits

  I'm having a difficult time understanding how to get Rails to show explicitly the error messages that a child resource is failing on when I render an XML template. Hypothetically, I have the following classes: class School < ActiveRecord::Base has_many :students validates_associated :students end class Student < ActiveRecord::Base belongs_to :school validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i, :message => "You must supply a valid email" end Now, in the controller, let's say we want to build a trivial API to allow us to add a new School with a student in it (again, I said, it's a terrible example, but plays its role for the purpose of the question) class SchoolsController < ApplicationController def create @school = School.new @student = school.students.build @student.email = "bad@email" respond_to do |format| if @school.save # some code else format.xml { render :xml => @school.errors, :status => :unprocessable_entity } end end end end Now the validation is working just fine, things die because the email doesn't match the regex that's set in the validates_format_of method in the Student class. However the output I get is the following: <?xml version="1.0" encoding="UTF-8"?> <errors> <error>Students is invalid</error> </errors> I want the more meaningful error message that I set above with validates_format_of to show up. Meaning, I want it to say: <error>You must supply a valid email</error> What am I doing wrong for that not to show up?

• How to create a JAX-RS service where the sub-resource @Path doesn't have a leading slash

  - by Matt

  I've created a JAX-RS service (MyService) that has a number of sub resources, each of which is a subclass of MySubResource. The sub resource class being chosen is picked based on the parameters given in the MyService path, for example: @Path("/") @Provides({"text/html", "text/xml"}) public class MyResource { @Path("people/{id}") public MySubResource getPeople(@PathParam("id") String id) { return new MyPeopleSubResource(id); } @Path("places/{id}") public MySubResource getPlaces(@PathParam("id") String id) { return new MyPlacesSubResource(id); } } where MyPlacesSubResource and MyPeopleSubResource are both sub-classes of MySubResource. MySubResource is defined as: public abstract class MySubResource { protected abstract Results getResults(); @GET public Results get() { return getResults(); } @GET @Path("xml") public Response getXml() { return Response.ok(getResults(), MediaType.TEXT_XML_TYPE).build(); } @GET @Path("html") public Response getHtml() { return Response.ok(getResults(), MediaType.TEXT_HTML_TYPE).build(); } } Results is processed by corresponding MessageBodyWriters depending on the mimetype of the response. While this works it results in paths like /people/Bob/html or /people/Bob/xml where what I really want is /people/Bob.html or /people/Bob.xml Does anybody know how to accomplish what I want to do?

• Canonical resource for forms-based design in ASP.NET MVC?

  - by Robert Harvey

  Is there a resource on the web that describes various form scenarios in ASP.NET MVC, and gives example solutions within a sensible, consistent design philosophy? Examples of such scenarios might be: One-to-many forms, like invoice data-entry forms. Foreign-table forms such as Add New User in a form that requires specifying a user Forms that require dynamic interaction, using Ajax or JSON. Popup forms Forms requiring multiple data records to be input, without postbacks. Note that there is considerable conceptual and technological overlap among these example scenarios. I am aware that there is a vast patchwork quilt of available technologies and examples out there that provide partial solutions and pieces of solutions, such as jQuery Ajax, CSS, and so forth. But I would like guidance in using these technologies in more effective and consistent ways. I am not considering web forms integration with an ASP.NET MVC application; I would still like my applications to be pure MVC. Nor am I, at the moment, considering a paid solution like Telerik. But I would like to know if someone has already done some of the work combining these technologies into a consistent, cohesive whole, that follows a sensible design philosophy. (an open source framework, perhaps?)

• pushing view controller inside a tab bar from app delegate, after a notification.

  hi i have an app with tab bar and a navigation controller inside every tab. i have set a notification that when it lunches the user can get lunch the app by pressing the action on the alert. i want to redirect the user to one of the views inside one of the controllers. i have tried this: (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif { NSArray *data = [notif.userInfo objectForKey:@"todoDate"]; NSInteger ind = [[data objectAtIndex:2] integerValue]; QuickViewController *detailViewController ; detailViewController = [[QuickViewController alloc] initWithNibName:@"QuickViewController" bundle:nil]; detailViewController.title = @"Edit"; detailViewController.personName = [data objectAtIndex:0]; detailViewController.DelitionDate=[data objectAtIndex:1]; detailViewController.personCategory=@"NO Category"; detailViewController.personID = ind r ; rootControler.selectedIndex = 1; [rootControler.tabBarController.selectedViewController.navigationController pushViewController:detailViewController animated:YES]; } but nothing is happening (no crashing) except of the :rootControler.selectedIndex = 1; when i tried : presentModalViewController i got the view perfectly but without the navigation controller. thanks shani

• How can I shared controller logic in ASP.NET MVC for 2 controllers, where they are overriden

  - by AbeP

  Hello, I am trying to implement user-friendly URLS, while keeping the existing routes, and was able to do so using the ActionName tag on top of my controller (http://stackoverflow.com/questions/436866/can-you-overload-controller-methods-in-asp-net-mvc) I have 2 controllers: ActionName("UserFriendlyProjectIndex")] public ActionResult Index(string projectName) { ... } public ActionResult Index(long id) { ... } Basically, what I am trying to do is I store the user-friendly URL in the database for each project. If the user enters the URL /Project/TopSecretProject/, the action UserFriendlyProjectIndex gets called. I do a database lookup and if everything checks out, I want to apply the exact same logic that is used in the Index action. I am basically trying to avoid writing duplicate code. I know I can separate the common logic into another method, but I wanted to see if there is a built-in way of doing this in ASP.NET MVC. Any suggestions? I tried the following and I go the View could not be found error message: [ActionName("UserFriendlyProjectIndex")] public ActionResult Index(string projectName) { var filteredProjectName = projectName.EscapeString().Trim(); if (string.IsNullOrEmpty(filteredProjectName)) return RedirectToAction("PageNotFound", "Error"); using (var db = new PIMPEntities()) { var project = db.Project.Where(p => p.UserFriendlyUrl == filteredProjectName).FirstOrDefault(); if (project == null) return RedirectToAction("PageNotFound", "Error"); return View(Index(project.ProjectId)); } } Here's the error message: The view 'UserFriendlyProjectIndex' or its master could not be found. The following locations were searched: ~/Views/Project/UserFriendlyProjectIndex.aspx ~/Views/Project/UserFriendlyProjectIndex.ascx ~/Views/Shared/UserFriendlyProjectIndex.aspx ~/Views/Shared/UserFriendlyProjectIndex.ascx Project\UserFriendlyProjectIndex.spark Shared\UserFriendlyProjectIndex.spark I am using the SparkViewEngine as the view engine and LINQ-to-Entities, if that helps. thank you!

• Why does Rails screw up timezones when I am editing a resource?

  - by DJTripleThreat

  Steps to produce this: prompt>rails test_app prompt>cd test_app prompt>script/generate scaffold date_test my_date:datetime prompt>rake db:migrate now edit your app/views/date_tests/edit.html.erb: <h1>Editing date_test</h1> <% form_for(@date_test) do |f| %> <%= f.error_messages %> <p> RIGHT!<br/> <%= text_field_tag @date_test, f.object.my_date %> </p> <p> WRONG!<br /> <%= f.text_field :my_date %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> <%= link_to 'Show', @date_test %> | <%= link_to 'Back', date_tests_path %> now edit your config/environment.rb: #add this config.time_zone = 'Central Time (US & Canada)' This recreates the problem I am having in my actual app. The problem with my app is that I'm storing a date in a hidden field and rendering a "user friendly" version. Creating a resource works fine but as soon as I try to edit it the time changes (it adds the difference between my current time zone configuration and UTC). go to http://localhost:3000/date_tests/new and save the time then go to reedit it and you will have two different representations of the date/time one which will save incorrectly and the other that will.

• Controller actions appear to be synchronous though on different requests?

  - by Oded

  I am under the impression that the below code should work asynchronously. However, when I am looking at firebug, I see the requests fired asynchronously, but the results coming back synchronously: Controller: [HandleError] public class HomeController : Controller { public ActionResult Status() { return Content(Session["status"].ToString()); } public ActionResult CreateSite() { Session["status"] += "Starting new site creation"; Thread.Sleep(20000); // Simulate long running task Session["status"] += "<br />New site creation complete"; return Content(string.Empty); } } Javascript/jQuery: $(document).ready(function () { $.ajax({ url: '/home/CreateSite', async: true, success: function () { mynamespace.done = true; } }); setTimeout(mynamespace.getStatus, 2000); }); var mynamespace = { counter: 0, done: false, getStatus: function () { $('#console').append('.'); if (mynamespace.counter == 4) { mynamespace.counter = 0; $.ajax({ url: '/home/Status', success: function (data) { $('#console').html(data); } }); } if (!mynamespace.done) { mynamespace.counter++; setTimeout(mynamespace.getStatus, 500); } } } Addtional information: IIS 7.0 Windows 2008 R2 Server Running in a VMWare virutual machine Can anyone explain this? Shouldn't the Status action be returning practically immediately instead of waiting for CreateSite to finish? Edit: How can I get the long running process to kick off and still get status updates?

• Pass object from JSON into MVC Controller - its always null ?

  - by SteveCl

  Hi I have seen a few questions on here related to the a similar issue, I have read them, followed them, but still i have the same problem. I am basically creating an object in javascript and trying to call a method on the controller that will return a string of html. Not JSON. I've been playing around with dataType and contentType but still no joy. So apologies if the code snippets are a bit messy. Build the object in JS. function GetCardModel() { var card = {}; card.CardTitle = $("#CardTitle").val(); card.TopicTitle = $("#TopicTitle").val(); card.TopicBody = $("#TopicBody").data("tEditor").value(); card.CardClose = $("#CardClose").val(); card.CardFromName = $("#CardFromName").val(); return card; } Take a look at the object - all looks good and as it should in JSON. var model = GetCardModel(); alert(JSON.stringify(GetCardModel())); Make the call... $.ajax({ type: "POST", url: "/Postcard/Create/Preview/", dataType: "json", //contentType: "application/json", date: GetCardModel(), processData: true, success: function (data) { alert("im back"); alert(data); }, error: function (xhr, ajaxOptions, error) { alert(xhr.status); alert("Error: " + xhr.responseText); //alert(error); } }); Always when I step into the controller, the object is ALWAYS there, but with null values for all the properties.

Both bean objects end up with only null values. Can anyone see anything wrong with the code? I know that I could use strings instead of the int, but never mind that at this point.

• Where should my "filtering" logic reside with Linq-2-SQL and ASP.NET-MVC in View or Controller?

  - by Nate Bross

  I have a main Table, with several "child" tables. TableA and TableAChild1 and TableAChild2. I have a view which shows the information in TableA, and then has two columns of all items in TableAChild1 and TableAChild2 respectivly, they are rendered with Partial views. Both child tables have a bit field for VisibleToAll, and depending on user role, I'd like to either display all related rows, or related rows where VisibleToAll = true. This code, feels like it should be in the controller, but I'm not sure how it would look, because as it stands, the controller (limmited version) looks like this: return View("TableADetailView", repos.GetTableA(id)); Would something like this be even work, and would it be bad what if my DataContext gets submitted, would that delete all the rows that have VisibleToAll == false? var tblA = repos.GetTableA(id); tblA.TableAChild1 = tblA.TableAChild1.Where(tmp => tmp.VisibleToAll == true); tblA.TableAChild2 = tblA.TableAChild2.Where(tmp => tmp.VisibleToAll == true); return View("TableADetailView", tblA); It would also be simple to add that logic to the RendarPartial call from the main view: <% Html.RenderPartial("TableAChild1", Model.TableAChild1.Where(tmp => tmp.VisibleToAll == true); %>

• what is the wrong with this spec and controller code?

  - by user1609468

  I'm trying to test an existing rails project with rspec. And I want to test a controller but getting an error which I can't solve :S Here is the my spec code ; require 'spec_helper' describe BriefNotesController do before(:all) do @customer=Factory(:customer) @project=Factory(:project_started, :owner => @customer) end context 'get :new' do it 'should redirect to login page for not signed in users' do get :new, :project_id => @project.id response.should redirect_to("/kullanici-girisi") end it 'should be success and render new brief note page for project owner' do sign_in @customer get :new, :project_id => @project.id response.should be_success end end end Here is the my controller code ; class BriefNotesController < ApplicationController before_filter :authenticate_user! before_filter :find_project def new @brief_note = @project.brief_notes.new end def create @brief_note = @project.brief_notes.build(params[:brief_note]) if @brief_note.save redirect_to brief_project_path(@project) else render :action => :new end end private def find_project @project = current_user.projects.find_by_cached_slug([params[:project_id]]) end end I think current_user.projects.find_by_cached_slug method don't work. So this is the error; Failures: 1) BriefNotesController get :new should be success and render new brief note page for project owner Failure/Error: get :new, :project_id => @project.id NoMethodError: undefined method `brief_notes' for nil:NilClass # ./app/controllers/brief_notes_controller.rb:6:in `new' # ./spec/controllers/brief_notes_controller_spec.rb:19:in `block (3 levels) in <top (required)>'

• One controller with multiple models? Am I doing this correctly?

  - by user363243

  My web app, up until this point, has been fairly straight forward. I have Users, Contacts, Appointments and a few other things to manage. All of these are easy - it's just one model per section so I just did a scaffold for each, then modified the scaffolded code to fit my need. Pretty easy... Unfortunately I am having a problem on this next section because I want the 'Financials' section of my app to be more in depth than the other sections which I simply scaffolded. For example, when the user clicks the 'Contacts' link on the navigation bar, it just shows a list of contacts, pretty straight forward and is in line with the scaffold. However, when the user clicks the 'Financials' link on the navigation bar, I want to show the bank accounts on the left of the page and a few of the transactions on the right. So the financials tab will basically work with data from two models: transactions and bank_accounts. I think I should make the models (transactions & bank_accounts) and then make a controller called Financials, then I can query the models from the Financials controller and display the pages in app/views/financials/ Am I correct in this app layout? I have never worked with more than the basics of scaffolding so I want to ensure I get this right! Thank you!

• How to configure a zone cluster on Solaris Cluster 4.0

  - by JuergenS

  This is a short overview on how to configure a zone cluster on Solaris Cluster 4.0. This is a little bit different as in Solaris Cluster 3.2/3.3 because Solaris Cluster 4.0 is only running on Solaris 11. The name of the zone cluster must be unique throughout the global Solaris Cluster and must be configured on a global Solaris Cluster. Please read all the requirements for zone cluster in Solaris Cluster Software Installation Guide for SC4.0. For Solaris Cluster 3.2/3.3 please refer to my previous blog Configuration steps to create a zone cluster in Solaris Cluster 3.2/3.3. A. Configure the zone cluster into the already running global clusterCheck if zone cluster can be created # cluster show-netprops to change number of zone clusters use # cluster set-netprops -p num_zoneclusters=12 Note: 12 zone clusters is the default, values can be customized! Create config file (zc1config) for zone cluster setup e.g: Configure zone cluster # clzc configure -f zc1config zc1 Note: If not using the config file the configuration can also be done manually # clzc configure zc1 Check zone configuration # clzc export zc1 Verify zone cluster # clzc verify zc1 Note: The following message is a notice and comes up on several clzc commands Waiting for zone verify commands to complete on all the nodes of the zone cluster "zc1"... Install the zone cluster # clzc install zc1 Note: Monitor the consoles of the global zone to see how the install proceed! (The output is different on the nodes) It's very important that all global cluster nodes have installed the same set of ha-cluster packages! Boot the zone cluster # clzc boot zc1 Login into non-global-zones of zone cluster zc1 on all nodes and finish Solaris installation. # zlogin -C zc1 Check status of zone cluster # clzc status zc1 Login into non-global-zones of zone cluster zc1 and configure the shell environment for root (for PATH: /usr/cluster/bin, for MANPATH: /usr/cluster/man) # zlogin -C zc1 If using additional name service configure /etc/nsswitch.conf of zone cluster non-global zones. hosts: cluster files netmasks: cluster files Configure /etc/inet/hosts of the zone cluster zones Enter all the logical hosts of non-global zones B. Add resource groups and resources to zone cluster Create a resource group in zone cluster # clrg create -n <zone-hostname-node1>,<zone-hostname-node2> app-rg Note1: Use command # cluster status for zone cluster resource group overview. Note2: You can also run all commands for zone cluster in global cluster by adding the option -Z to the command. e.g: # clrg create -Z zc1 -n <zone-hostname-node1>,<zone-hostname-node2> app-rg Set up the logical host resource for zone cluster In the global zone do: # clzc configure zc1 clzc:zc1 add net clzc:zc1:net set address=<zone-logicalhost-ip> clzc:zc1:net end clzc:zc1 commit clzc:zc1 exit Note: Check that logical host is in /etc/hosts file In zone cluster do: # clrslh create -g app-rg -h <zone-logicalhost> <zone-logicalhost>-rs Set up storage resource for zone cluster Register HAStoragePlus # clrt register SUNW.HAStoragePlus Example1) ZFS storage pool In the global zone do: Configure zpool eg: # zpool create <zdata> mirror cXtXdX cXtXdX and # clzc configure zc1 clzc:zc1 add dataset clzc:zc1:dataset set name=zdata clzc:zc1:dataset end clzc:zc1 verify clzc:zc1 commit clzc:zc1 exit Check setup with # clzc show -v zc1 In the zone cluster do: # clrs create -g app-rg -t SUNW.HAStoragePlus -p zpools=zdata app-hasp-rs Example2) HA filesystem In the global zone do: Configure SVM diskset and SVM devices. and # clzc configure zc1 clzc:zc1 add fs clzc:zc1:fs set dir=/data clzc:zc1:fs set special=/dev/md/datads/dsk/d0 clzc:zc1:fs set raw=/dev/md/datads/rdsk/d0 clzc:zc1:fs set type=ufs clzc:zc1:fs add options [logging] clzc:zc1:fs end clzc:zc1 verify clzc:zc1 commit clzc:zc1 exit Check setup with # clzc show -v zc1 In the zone cluster do: # clrs create -g app-rg -t SUNW.HAStoragePlus -p FilesystemMountPoints=/data app-hasp-rs Example3) Global filesystem as loopback file system In the global zone configure global filesystem and it to /etc/vfstab on all global nodes e.g.: /dev/md/datads/dsk/d0 /dev/md/datads/dsk/d0 /global/fs ufs 2 yes global,logging and # clzc configure zc1 clzc:zc1 add fs clzc:zc1:fs set dir=/zone/fs (zc-lofs-mountpoint) clzc:zc1:fs set special=/global/fs (globalcluster-mountpoint) clzc:zc1:fs set type=lofs clzc:zc1:fs end clzc:zc1 verify clzc:zc1 commit clzc:zc1 exit Check setup with # clzc show -v zc1 In the zone cluster do: (Create scalable rg if not already done) # clrg create -p desired_primaries=2 -p maximum_primaries=2 app-scal-rg # clrs create -g app-scal-rg -t SUNW.HAStoragePlus -p FilesystemMountPoints=/zone/fs hasp-rs More details of adding storage available in the Installation Guide for zone cluster Switch resource group and resources online in the zone cluster # clrg online -eM app-rg # clrg online -eM app-scal-rg Test: Switch of the resource group in the zone cluster # clrg switch -n zonehost2 app-rg # clrg switch -n zonehost2 app-scal-rg Add supported dataservice to zone cluster Documentation for SC4.0 is available here Example output: Appendix: To delete a zone cluster do: # clrg delete -Z zc1 -F + Note: Zone cluster uninstall can only be done if all resource groups are removed in the zone cluster. The command 'clrg delete -F +' can be used in zone cluster to delete the resource groups recursively. # clzc halt zc1 # clzc uninstall zc1 Note: If clzc command is not successful to uninstall the zone, then run 'zoneadm -z zc1 uninstall -F' on the nodes where zc1 is configured # clzc delete zc1
