  • Conditional root_url (index)

    - by vise
    I'd like my application to display different data on the frontpage depending on whether the user has been logged in or not. def index if current_user # render another controllers action else # render another controllers action end end I can achieve this by using render_component. However it has been obsolete for some time. Although I can still use it as a plugin, I'm interested if anyone has a better approach. Just take in mind that rendering another controller's view directly is not an option. Thanks.

  • Javascript split with RegEx

    - by Rohan
    Hey again, I just asked a question about Regex, and received a great answer: http://stackoverflow.com/questions/3047201/javascript-split-without-losing-character Now, I have another question. My current Regex looks like this: var split = text.split(/(?=\w*\d*\d:\d\d)/); Basically, I'm trying to split using the timestamps (eg - 9:30 or 10:30, the difference between them is the extra digit in the latter). How do I go about this? Currently, if I have these two: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. The splits are : 9:30 pm The user did action A. ---- 1 ---- 0:30 pm Welcome, user John Doe. How do I add an optional check for the first character in the timestamp? Thanks!

  • How to pass an int value on UIButton click inside UITableView

    - by Toran Billups
    So I have a view controller with a single UITableView that shows a string to the user. But I needed a way to have the user select this object by id using a normal UIButton so I added it as a subview and the click event works as expected. The issue is this - how can I pass an int value to this click event? I've tried using attributes of the button like button.tag or button.accessibilityhint without much success. How do the professionals pass an int value like this? Also it's important that I can get the actual [x intValue] from the int later in the process. A while back I thought I could do this with a simple NSLog(@"the actual selected hat was %d", [obj.idValue intValue]); But this doesn't appear to work (any idea how I can pull the actual int value directly from the variable?). The working code I have is below - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } if ([self.hats count] > 0) { Hat* obj = [self.hats objectAtIndex: [indexPath row]]; NSMutableString* fullName = [[NSMutableString alloc] init]; [fullName appendFormat:@"%@", obj.name]; [fullName appendFormat:@" %@", obj.type]; cell.textLabel.text = fullName; cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; //add the button to subview hack UIButton* button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button.frame = CGRectMake(50, 5, 50, 25); [button setTitle:@"Select" forState:UIControlStateNormal]; button.backgroundColor = [UIColor clearColor]; button.adjustsImageWhenHighlighted = YES; button.tag = obj.idValue; //this is my current hack to add the id but no dice :( [button addTarget:self action:@selector(action:) forControlEvents:UIControlEventTouchUpInside]; [cell.contentView addSubview:button]; //hack } return cell; } - (void)action:(id)sender { int* hatId = ((UIButton *)sender).tag; //try to pull the id value I added above ... //do something w/ the hatId }

  • Update database using restful ASP.NET MVC 1.0

    - by Mike
    We are building an MVC 1.0 application right now and using Linq - SQL for our DAL. Following the restful approach we have multiple action events depending on if you are updating or loading or what not. The two that I'm concerned with at this point are the edit and update action methods. Here is the signatures. public ActionResult Update(int customerId, int Id, AggregateModel viewModel) public ActionResult Edit(int customerId, int Id, AggregateModel viewModel) So the idea is that in the Edit method we load up our viewModel and pass it to the view. The user makes changes to the model and then posts back to the Update method. The first thing I could think of to do would be to get the viewModel from the database again, copy the changes in one by one from the posted back model and then submit it back. This would work but does seem clunky to me. What is the best way to insert those changes into the database at this point?

  • On a Hudson master node, what are the .tmp files created in the workspace-files folder?

    - by Patrick Johnmeyer
    Question: In the path HUDSON_HOME/jobs/<jobname>/builds/<timestamp>/workspace-files, there are a series of .tmp files. What are these files, and what feature of Hudson do they support? Background Using Hudson version 1.341, we have a continuous build task that runs on a slave instance. After the build is otherwise complete, including archiving the artifacts, task scanner, etc., the job appears to hang for a long period of time. In monitoring the master node, I noted that many .tmp files were being created and modified under builds//workspace=files, and that some of them were very large. This appears to be causing the delay, as the job completed at the same time that files in this path stopped changing. Some key configuration points of the job: It is tied to a specific slave node It builds in a 'custom workspace' It triggers a downstream job that builds in the same custom workspace on the same slave node

  • User-customizable rails authorization

    - by neutrino
    Hello everyone, Seems there is an abundance of popular declarative-style authorization plugins, which allow you to somehow state in the code that, e.g., this controller action can be accessed by users with such-and-such roles. But what if I need a more dynamic scheme. I want to have an admin area, with a list of all authorizable actions and an ability to assign permissions on actions from the UI. I have ideas how to implement it from scratch, like to define a model corresponding to a controller and/or action and store the permissions via normal associations. Just wonder if there are any ready solutions to this. Thanks a lot

  • Oracle global_names DELETE problem

    - by jyzuz
    I'm using a database link to execute a DELETE statement on another DB, but the DB link name doesn't conform to global naming, and this requirement cannot change. Also I have global_names set to false, and cannot be changed either. When I try to use these links however, I receive: ORA-02069: - global_names parameter must be set to TRUE for this operation Cause: A remote mapping of the statement is required but cannot be achieved because GLOBAL_NAMES should be set to TRUE for it to be achieved. - Action: Issue `ALTER SESSION SET GLOBAL_NAMES = TRUE` (if possible) What is the alternative action when setting global_names=true is not possible? Cheers, Jean

  • Struts 1 - problem in showing ActionMessages through a JSP page

    - by Yatendra Goel
    I am using Struts 1.3.10. I am trying to display ActionMessage and ActionError set by Action class through a JSP page. The problem is that the ActionErrors are displaying well but ActionMessages are not displaying. When I debug the application, I found that the messages (reference variable of ActionMessages) contains messages. I also saved those messages through saveMessages(request, messages) method of Action class. So, I think that the problem is in the JSP code through which I am trying to display those messages. The JSP code is as follows: <logic:messagesPresent> <ul id="messsages"> <html:messages id="msg" message="true"> <li><bean:write name="msg"/> </li> </html:messages> </ul> </logic:messagesPresent>

  • Event is causing an error, but I can't catch the exception

    - by proudgeekdad
    A developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line. Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound Try ProcessBadData... Catch ex As Exception Throw ex End Try End Sub In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. Any ideas how I can capture the exception in this ASCX control so I can report it to the user?

  • I am having trouble with my first project in ruby on rails

    - by Sebastian
    Here's my index action in the books controller: http://pastebin.com/XdtGRQKV Here's the view for the action i just mentioned: http://pastebin.com/nQFy400m Here's the result without being logged in: http://i.imgur.com/rQoiw.jpg Here's the result when i'm logged in with the user 'admin': http://i.imgur.com/E1CUr.jpg So the problem is that, in the view, before line 25 the 'user' variable seems to be empty ( or not loaded), and after line 25 the variable 'user' has the expected values. I have tried initializing a variable in the index method of the books controller but get exactly the same results. Thanks in advance! BTW had to make the links text because of stackoverflow limit.

  • History tables pros, cons and gotchas - using triggers, sproc or at application level.

    - by Nathan W
    I am currently playing around with the idea of having history tables for some of my tables in my database. Basically I have the main table and a copy of that table with a modified date and an action column to store what action was preformed eg Update,Delete and Insert. So far I can think of three different places that you can do the history table work. Triggers on the main table for update, insert and delete. (Database) Stored procedures. (Database) Application layer. (Application) My main question is, what are the pros, cons and gotchas of doing the work in each of these layers. One advantage I can think of by using the triggers way is that integrity is always maintained no matter what program is implmentated on top of the database.

  • How do you render a rails partial that is outside of a namespace in a view that is inside of a namespace?

    - by iand675
    I've got a 'static' controller and static views that are pages that don't utilize ruby in their views. For these pages, I have a sitemap partial that is generated programatically and used in the application layout file. Namespaced routes still use the application layout file but are taking the static routes and trying to namespace them too. Here's the relevant portion of the route file: namespace :admin do resources :verse_categories resources :verses resources :songs resources :flowers resources :visits, :except => [:new, :create] end match ':action' => 'static' root :to => 'static#home' Here's the error I'm getting: No route matches {:controller=>"admin/static", :action=>"about"} Note that about is one of the static pages that the sitemap partial uses. So, how can I resolve this routing issue so that it's not trying to find my static sites inside of the admin namespace? Any help would be appreciated!

  • What is the difference between Invoking and BeginInvoking a MessageBox?

    - by mafutrct
    In a form, compare BeginInvoke (new Action (() => { MessageBox.Show ()); })); with Invoke (new Action (() => { MessageBox.Show ()); })); What is the difference, and when should I use one over the other? How is the behavior affected by the message pump of the MessageBox? I did some testing and found that both methods block the UI. The only difference is that Invoke is actually called instantly while BeginInvoke takes a (very short) time until the code is run. This is to be expected.

  • Display two images side by side on an HTML Page

    - by user77735
    I am trying to place two images of the same size side-by-side. If I use a "table" then I am able to display both images side-by-side. But in my CSS Stylesheet I am using a custom format for the table and this shows on the page containing the images too. But I want to just display both images without any custom background or border etc. I tried using "div", "span", "ul" & "li" etc. but failed in each case. How can I place two images (of same size) in a single line, without using a "table"? If I have to use "table" for the same, then how can I use two (or more) different formatting for my tables using CSS? Thank you. Lalit Kumar Barik

  • How to customize JBoss AS7 404 page

    - by user23308
    I already created a custom 404 page inside my web app deployed in JBoss AS 7.1. So if my app is at fubar dot com :8080/Myapp and I go to fubar dot com :8080/Myapp/xyzzy, I get the custom error page (defined in the web app's web.xml file). However, when I go to fubar dot com :8080/xyzzy, JBoss displays the default 404 page which discloses that it's JBoss and which JBoss version. I need to replace this page in order to hide this information. Please advise.
