  • Simple CanCan problem

    - by sscirrus
    I have just started with CanCan and here's a sample of the code: # Ability.rb def initialize(user) user ||= User.new can :read, Link end # view.html.erb <% if can? :read, @link %> ... <% end %> This is from the github repo for CanCan but this doesn't seem to work (it returns false and stops the ... code from running). When I change the view to <% if can? :read, Link %>, it works. But, this is different to the CanCan readme. Do you know where I'm going wrong here?

  • Load a UIView from a NIB

    - by Winder
    I have been using UIViewControllers and initWithNibName with much success, basically using them as a convenient way to design the view with Interface Builder. Unfortunately I have built a hierarchy of views before noticing this line in the UIViewController documentation: Note: You should not use view controllers to manage views that fill only a part of their window My question is this: Having a very simple NIB that only has a UIView in addition to the default First Responder and Owning Object, what is the simplest way to load the UIView into my code? I have not been able to get loadNibNamed:owner:options: to work at this point, but suspect the answer will involve it somehow.

  • WPF TreeView PreviewMouseDown on TreeViewItem

    - by imekon
    If I handle the PreviewMouseDown event on TreeViewItem, I get events for everything I click on that TreeViewItem include the little +/- box to the left (Windows XP). How can I distinguish that? I tried the following: // We've had a single click on a tree view item // Unfortunately this is the WHOLE tree item, including the +/- // symbol to the left. The tree doesn't do a selection, so we // have to filter this out... MouseDevice device = e.Device as MouseDevice; // This is bad. The whole point of WPF is for the code // not to know what the UI has - yet here we are testing for // it as a workaround. Sigh... // This is broken - if you click on the +/- on a item, it shouldn't // go on to be processed by OnTreeSingleClick... ho hum! if (device.DirectlyOver.GetType() != typeof(Path)) { OnTreeSingleClick(sender); } What I'm after is just single click on the tree view item excluding the extra bits it seems to include.

  • How to add UIview over a ViewController and its NavigationController

    - by Roxee Man
    I have a ViewController with a NavigationController and I want to add a translucent UIView with some Buttons over the ViewController when I press a ViewController button, the problem is that I can not put the UIView over the NavigationBar. How can I solve this? This is my code ( Very simple) -(void)setOpacityView { opacityVw = [[UIView alloc] initWithFrame:self.view.bounds]; opacityVw.backgroundColor = [[UIColor alloc] initWithRed:0.0 green:0.0 blue:0.0 alpha:0.8]; WPCustomButton *closeBtn = [[WPCustomButton alloc] initWithFrame:CGRectMake(230, 10, 80, 20)]; [closeBtn setTitle:@"Close X" forState:UIControlStateNormal]; [closeBtn setBackgroundColor:[UIColor clearColor]]; [closeBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal]; [closeBtn addTarget:self action:@selector(closeView) forControlEvents:UIControlEventTouchUpInside]; [opacityVw addSubview:closeBtn]; } // --------------------------------------------------------------------------------------------------------------------- #pragma mark - Button methods -(void) closeView { [opacityVw removeFromSuperview]; } -(void)setProfileImage { [self setOpacityView]; [self.view addSubview:opacityVw]; }

  • How to copy newly added document with metadata to another document library?

    - by James
    I need to copy the item that user just added (for example. myresume.doc or financial.xls) with the metadata (doc lib obtains the columns from content type, ct obtains the columns from site colum) and copy the item with metadata in a folder called "NativeFile". Every doc library has this folder. I know itemadded can be used but then I heard itemadded fires before user have a chance to complete the metadata for the item they just added. What are my options? (new to sp, so some sample code would greatly help. or some good link similar to this issue) Sharepoint 2007, itemadded or itemadding or itemupdating or itemupdated....

  • UIScrollView: Is 806k Image too much too handle? (Crash, out of memory)?

    - by Jordan
    I'm loading a 2400x1845 png image into a scroll view.

  • Drupal Views Bonus Pack export issue

    - by evanmcd
    Hi, In trying to solve the problem of getting data from Drupal into XML, I found the Views Bonus Pack module, which with a little figuring out works great. Except... When setting the Style property in the Basic settings of Feed view to XML file no items show up unless I am authenticated. If I log in, I see all the entries. If I log out, I see only <xml> <node/> </xml> The Access setting is set to unrestricted in both the Defaults and the Feed view. Anybody have any ideas as to how to fix this? Thanks a lot.

  • Using setSourceType with image picker up hides status bar

    - by Aaron
    I am pretty sure this is a bug but I thought I would check. I used the camera overlay to add a button so that on the iphone a user can switch from the camera view to the photo library. When button is taped the source type switches fine but the status bar is missing from the photo library. Throughout the rest of that session the status bar remains missing from all views evet thougth isStatusBarHidden reports NO. This is how the camera overlay view is created if (cameraOverlayView == nil) { [[NSBundle mainBundle] loadNibNamed:@"CameraOverlayView" owner:self options:nil]; } If camera is available this is when I set source type and add overlay if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) { [imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera]; [imagePicker setCameraOverlayView:cameraOverlayView]; } Here is the action statement to change source type. (IBAction)selectImage; { [imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; } If I don't tap the button on the overlay there is no problem with the status bar. PS. I did submit a bug report on this.

  • UITabBarController "More" tab issues

    - by codemonkey
    I've got a UITabBarController with 7 tabs. Each of the 7 tabs has its own UINavigationController and customizes its toolbar. When a view is loaded via the UITabBarController's "More" menu its custom toolbar isn't appearing. If i switch the order of the views around so that the same view is now accessible from the UITabBar without going through the "More" menu then the custom toolbar shows up like it's supposed to. Is there a way to customize a NavigationController's toolbar when that NavigationController is loaded via the "More" menu of a TabBarController? I'm actually also interested in replacing the "More" menu navigation controller with my own custom one on views loaded via the "More" menu... not sure whether that's even possible. Any feedback will be appreciated.

  • Why are my ActiveRecord class instance variables disappearing after the first request in development

    - by Paul C
    I have a class instance variable on one of my AR classes. I set its value at boot with an initializer and, after that, never touch it again except to read from it. In development mode, this value disappears after the first request to the web server. However, when running tests, using the console or running the production server this does not happen. # The AR class class Group < ActiveRecord::Base class << self attr_accessor :path end end # The initializer Group.path = File.join(RAILS_ROOT, "public", "etc") # First request in a view %p= Group.path #=> "/home/rails/app/public/etc" # Second request in a view %p= Group.path #=> nil Is there something about development mode that nukes instance variables from classes with each request? If so, is there a way to disable this for specific variables or classes?

  • Django: Geocoding an address on form submission?

    - by User
    Trying to wrap my head around django forms and the django way of doing things. I want to create a basic web form that allows a user to input an address and have that address geocoded and saved to a database. I created a Location model: class Location(models.Model): address = models.CharField(max_length=200) city = models.CharField(max_length=100) state = models.CharField(max_length=100, null=True) postal_code = models.CharField(max_length=100, null=True) country = models.CharField(max_length=100) latitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) longitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) And defined a form: class LocationForm(forms.ModelForm): class Meta: model = models.Location exclude = ('latitude','longitude') In my view I'm using form.save() to save the form. This works and saves an address to the database. I created a module to geocode an address. I'm not sure what the django way of doing things is, but I guess in my view, before I save the form, I need to geocode the address and set the lat and long. How do I set the latitude and longitude before saving?

  • Dojo slider: update value dynamically

    - by xApple
    I am building an application where the user browses certain objects by scrolling and zooming. To change the zoom level I have successfully implemented a "dijit.form.HorizontalSlider" object. Every time the user changes the position of the silder, I can catch the "onChange" call and do something with that. However, the user can also zoom-in by double clicking inside the view zone, at which point the slider should change position automatically to reflect the new zoom level. My question is the following: what function or method should I call in my javascript to update the position of a dojo silder ? Here is the code that creates the silder object: var zoomSlider = new dijit.form.HorizontalSlider({ name: "zoom_slider", id: "zoom_slider", value: 0, minimum: 0, maximum: 19, discreteValues: 20, intermediateChanges: false, style: "width: 160px;", onChange: function(value) { brwsr.view.zoomTo(value); } }, "zoom_slider"); navbox_silder.appendChild(zoomSlider.domNode);

    - by Paritosh Praharaj
    I'm trying to build a Rails app where I have to access the Zomato API Could anybody guide me on how to create the Controller and View. Suppose I want to get the name of the restaurant from this URL: Restaurant, how do I write the controller and views for it. Currently, I'm using HTTParty gem. This is my controller code: def restaurants @response = HTTParty.get("https://api.zomato.com/v1/restaurant.json/773", :headers => {"X-Zomato-API-Key" => "MYAPIKEY"}) puts response.body, response.code, response.message, response.headers.inspect @categories = Category.where(:category_name => 'Restaurants') end And I'm trying to get the response object in the view: <%= @response.each do |item| %> <td><%= item.id %></td> <td><%= item.name %></td> <td><%= item.url %></td> <% end %> So, this shows the following error: undefined method 'id' for ["id", 773]:Array

  • MVC Bootstrap: Autocomplete doesn't show properly

    - by kicked11
    I have a MVC website and it had a searchbox with autocomplete, now I changed the layout using bootstrap. But now the autocomplete isn't been shown correctly anymore. See the picture the suggestions are not shown right. the autocomplete goes through the text. I was fine before I used bootstrap. I am using a SQL server to get the data and this is js file (I'm not good at ajax, i took it from a tutorial I followed) $(function () { var ajaxFormSubmit = function () { var $form = $(this); var options = { url: $form.attr("action"), type: $form.attr("method"), data: $form.serialize() }; $.ajax(options).done(function (data) { var $target = $($form.attr("data-aptitude-target")); var $newHtml = $(data); $target.replaceWith($newHtml); $newHtml.show("slide", 200); }); return false; }; var submitAutocompleteForm = function (event, ui) { var $input = $(this); $input.val(ui.item.label); var $form = $input.parents("form:first"); $form.submit(); }; var createAutocomplete = function () { var $input = $(this); var options = { source: $input.attr("data-aptitude-autocomplete"), select: submitAutocompleteForm }; $input.autocomplete(options); }; $("form[data-aptituder-ajax='true']").submit(ajaxFormSubmit); $("input[data-aptitude-autocomplete]").each(createAutocomplete); }); this is the form in my view <form method="get" action="@Url.Action("Index")" data-aptitude-ajax="true" data-aptitude-target="#testList"> <input type="search" name="searchTerm" data-aptitude-autocomplete="@Url.Action("Autocomplete")" /> <input type="submit" value=Search /> And this is part of the controller of the view public ActionResult Autocomplete(string term) { var model = db.tests .Where(r => term == null || r.name.Contains(term)) .Select(r => new { label = r.name }); return Json(model, JsonRequestBehavior.AllowGet); } // // GET: /Test/ public ActionResult Index(string searchTerm = null) { var model = db.tests .Where(r => searchTerm == null || r.name.StartsWith(searchTerm)); if (Request.IsAjaxRequest()) { return PartialView("_Test", model); } return View(model); } I'm new to ajax as well as bootstrap 3. I got the searchfunction and autocomplete from a tutorial I followed. Anybody any idea on how to fix this, because it worked fine? Thanks in advance!

  • UIButton custom font vertical alignment

    - by Willshaw Media
    I've got a UIButton which uses a custom font, which is set when my view loads: - (void)viewDidLoad { [super viewDidLoad]; self.searchButton.titleLabel.font = [UIFont fontWithName: @"FONTNAME" size: 15.0 ]; } The problem I've got is that the font is appearing to float up of the center line. If I comment out this line, the default font appears vertically centered fine. But changing to the custom font breaks the vertical alignment. I'm getting the same issue on a Table Cell with a custom font too. Do I need to tell the view somewhere that the custom font is not as tall as other fonts? EDIT: I've just realized that the font I'm using is a Windows TrueType Font. I can use it fine in TextEdit on the Mac, only a problem with the alignment in my App

  • Will the app file be sync from dmgr side after we remove it from installedApps path in Websphere?

    - by wing2ofsky
    do you know whether the app file will be sync from dmgr side and regenerated after we remove it from installedApps path? i've got one issue recently from customer. That is, they uploaded one image file into WASNode installedApps app path manually. Afterwards, they removed that file manually again from installedApps app path. But after restarting the Application server process, that file has been regenerated under same installedApps path. So i suspect that file maybe has been resync from dmgr node, like app file under applications folder. However, first of all, i don't see that image file within application ear file from DMGR applications folder. Moreover, i made a test myself, if i deleted file from installedApps app path, that file never be regenerated any more even though the node sync completed. So does anybody know why? Thanks in advance

  • Recursive compilation using gcc

    - by curiousexplorer
    I am using the gcc compiler. My project source tree looks like somewhat like this test$~: tree . . |-- folder | |-- hello.cpp | `-- hello.h `-- main.cpp 1 directory, 3 files test$~: The file main.cpp contains the main() function and all the functions invoked by main.cpp lie in the directory named folder So far in all my little projects I never had to put some source code under a sub-directory. What I am looking for, in short, is some gcc command for recursive compilation in sub-directories and their subdirectories and so on... This command should be invoked from the home directory of the code project.

  • Does a program exist for checking two similar directories for file differences?

    - by John Sullivan
    Is there a program to compare one folder and all subfolders to another folder and all subfolders for differences in the files contained therein (presence, absence of files, size and list of filenames)? Example of usage: I have 100 DLL files from environment 1 and I want to check if any of them are different (in size and date modified) from the 100 DLL files in environment 2. So I copy and paste all the DLLs in environment 1 into directory A, and all the DLLs in environment 2 into directory B. I then run my "directory comparison" program on directories A and B and find out that, aha, here is a list of 7 DLLs that have different modified dates and times between the two directories. EDIT: OS is windows XP

  • Access Rules created by WSAT are not enforced

    - by rsteckly
    Hi, I'm trying to implement roles in my site. There are several projects in the solution, one of which is a web application. In that web application, I'm trying to use WSAT to create three roles. There are many folders for the application. I've used WSAT to define role based access rules for each folder. However, when I debug and navigate to those pages, they do not redirect to a login and show me the protected page. There are web.config files in each folder. Why would the system not enforce these rules? My web.config file has: I've tested the connections in WSAT and they work. Any ideas?

  • XCode: compiling doesn't always replace plist?

    - by Brian Postow
    I have an application and I will sometimes just change the plist, say to change the version number. Sometimes I'll actually make a change to the code, AND the version number....in the latter case, SOMETIMES the version number of the resulting app will change, in the former it will never change. The only way I've found that surely does it right is when I delete the .app before compiling. In case it matters, the resulting app is being put in a folder that isn't in the build folder, but I doubt that that's relevant. any thoughts?

  • Semantic Fish-eye zoom on table cells in UIKit?

    - by niblha
    How would I go about implementing a table view that looks and works something as illustrated in the link below, with UIKit for the iPhone? http://img442.imageshack.us/img442/4177/uifisheyeview.png I was thinking of using UITableView, and was looking a bit at the UITableViewDelegate methods tableView:willDisplayCell:forRowAtIndexPath: tableView:heightForRowAtIndexPath: But it seems as the UITableView will modify the cell frames after these methods are called and just before the cells are drawn? Maybe skipping the UITableView and go straight for some subclassing of a UIScrollView would be a better approach? So my question is basically that I would just like some overall thought in what might be the best ways to use existing UIKit components to implement this type of table view.

  • How can I create a shortcut to uninstall MyApplication using the Visual Studio Installer?

    - by Coder7862396
    I have created an installer for MyApplication using the Visual Studio Installer (VSI) Setup Project. I would like to create a shortcut in the user's Start Menu to uninstall MyApplication (instead of having to go through the Add/Remove Programs control panel). I cannot simply create a batch/script file to run the command "msiexec /uninstall {MyGUID}" because, although it does succeed in running the uninstaller, when the uninstall completes the program folder (wherever the user has chosen to install the app) does not get deleted. It stays empty. How can I create a shortcut that can uninstall the program but not leave behind an empty program folder?
