• Angular ng-style not changing with property

  - by ganaraj

  For the life of me I cant seem to figure out why the style property is not getting updated. In my larger application it seems to work fine. http://jsfiddle.net/ganarajpr/C2hRa/4/ Here is a fiddle which shows the issue I am currently facing. You will notice that the width and height are getting updated in the div when you change the input. But the style itself doesnt seem to be updating. Anyone can tell me what I am doing wrong here? I have tried all the following scenarios using $scope.$apply.. - Throws an error stating $apply already in progress.. $rootScope.$apply - same as above. Setting another variable in a service which is $watched in the other controller. - no change seen. It would be really cool if someone can get me an answer to this. Also would be really happy if you can tell me why exactly it is not getting updated.

• From where to send mails in a MVC framework, so that there is no duplication of code?

  - by Sabya

  It's a MVC question. Here is the situation: I am writing an application where I have "groups". You can invite other persons to your groups by typing their email and clicking "invite". There are two ways this functionality can be called: a) web interface and b) API After the mail sending is over I want to report to the user which mails were sent successfully (i.e., if the SMTP send succeeded. Currently, I am not interested in reporting mail bounces). So, I am thinking how should I design so that there is no code duplication. That is, API and web-interface should share the bulk of the code. To do this, I can create the method "invite" inside the model "group". So, the API and and the Web-interface can just call: group-invite($emailList); This method can send the emails. But the, problem is, then I have to access the mail templates, create the views for the mails, and then send the mails. Which should actually be in the "View" part or at least in the "Controller" part. What is the most elegant design in this situation? Note: I am really thinking to write this in the Model. My only doubt is: previously I thought sending mails also as "presentation". Since it is may be considered as a different form of generating output.

• Cocoa Touch: Creating and Adding Custom View

  - by Jason

  I create a custom view in cocoa touch that is superclassed by UIView and in my main controller I initialize it and then add it as a subview to the main view, but when I add it to the main view it calls my initializer method again and causes an infinite loop. Am I going about creating my custom view wrong? Here is the mainView (void)loadView { UIImage *tempImage = [UIImage imageNamed: @"image1.jpg"]; CustomImageContainer *testImage = [[CustomImageContainer alloc] initWithImage: tempImage andLabel: @"test image" onTop: true atX: 10 atY: 10]; [self.view addSubview: testImage]; } and the CustomImageContainer -(CustomImageContainer *) initWithImage: (UIImage *)imageToAdd andLabel: (NSString *)text onTop: (BOOL) top atX: (int) x_cord atY: (int) y_cord{ UIImageView *imageview_to_add = [[UIImageView alloc] initWithImage: imageToAdd]; imageview_to_add.frame = CGRectMake(0, 0, imageToAdd.size.width, imageToAdd.size.height); UILabel *label_to_add = [[UILabel alloc] init]; label_to_add.text = text; label_to_add.alpha = 50; label_to_add.backgroundColor = [UIColor blackColor]; label_to_add.textColor = [UIColor whiteColor]; [self addSubview: imageview_to_add]; self.frame = CGRectMake(x_cord, y_cord, imageToAdd.size.width, imageToAdd.size.height); if (top) { label_to_add.frame = CGRectMake(0, 0, imageview_to_add.frame.size.width, imageview_to_add.frame.size.height); //[self addSubview: label_to_add]; } else { label_to_add.frame = CGRectMake(0,.2 * imageview_to_add.frame.size.height, imageview_to_add.frame.size.width, imageview_to_add.frame.size.height); } [self addSubview: label_to_add]; [super init]; return self; }

• Multiple UIWebViewNavigationTypeBackForward not only false but make inferring the actual url impossi

  - by SG1

  I have a UIWebView and a UITextField for the url. Naturally, I want the textField to always show the current document url. This works fine for urls directly input in the field, but I also have some buttons attached to the view for reload, back, and forward. So I've added all the UIWebViewDelegate methods to my controller, so it can listen to whenever the webView navigates and change the url in the textField as needed. Here's how I'm using the shouldStartLoadWithRequest: method: - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType { NSLog(@"navigated via %d", navigationType); //loads the user cares about if ( navigationType == UIWebViewNavigationTypeLinkClicked || navigationType == UIWebViewNavigationTypeBackForward ) { //URL setting [self setUrlQuietly:request.URL]; } return YES; } Now, my problem here is that an actual click will generate a single navigation of type "LinkClicked" followed by a dozen type "Other" (redirects and ad loads I assume), which gets handled correctly by the code, but a back/forward action will generate all its requests as back/forward requests. In other words, a click calls setUrlQuietly: once, but a back/forward calls it multiple times. I am trying to use this method to determine if the user actually initiated the action (and I'd like to catch page redirects too). But if the method has no way of distinguishing between an actual "back" and a "load initiated as a result of a back", how can I make this assessment? Without this, I am completely stumped as to how I can only show the actual url and not intermediate urls. Thank you!

• Passing an Ajax variable to a Codeigniter function

  - by Matt

  Hello, I think this is a simple one. I have a Codeigniter function which takes the inputs from a form and inserts them into a database. I want to Ajaxify the process. At the moment the first line of the function gets the id field from the form - I need to change this to get the id field from the Ajax post (which references a hidden field in the form containing the necessary value) instead. How do I do this please? My Codeigniter Controller function function add() { $product = $this->products_model->get($this->input->post('id')); $insert = array( 'id' => $this->input->post('id'), 'qty' => 1, 'price' => $product->price, 'size' => $product->size, 'name' => $product->name ); $this->cart->insert($insert); redirect('home'); } And the jQuery Ajax function $("#form").submit(function(){ var dataString = $("input#id") //alert (dataString);return false; $.ajax({ type: "POST", url: "/home/add", data: dataString, success: function() { } }); return false; }); As always, many thanks in advance.

• Rails uploaded file blank

  - by Ceilingfish

  Hi chaps, I'm trying to upload a file to the server using a HTTP multipart form in rails, and for some reason it's turning up blank at the other end. I can see it being received in the rails log thusly: Processing Admin::HeadlinesController#update (for 127.0.0.1 at 2010-03-08 12:26:13) [PUT] Parameters: {"commit"=>"Save changes", "action"=>"update", "_method"=>"put", "authenticity_token"=>"mK70XRk5gOPUwXOcNboT/4K8PD9RBM7GqCOlEUKZwcA=", "headline"=>{"position"=>"1", "location"=>"primary", "attachment_id"=>"13", "headline_content"=>"questionnaires", "article_id"=>"3", "image"=>#<File:/tmp/RackMultipart20100308-63211-1vym9nj-0>}, "id"=>"140", "controller"=>"admin/headlines"} But if I have a look in /tmp/RackMultipart20100308-63211-1vym9nj-0 the file is blank.

• iPhone SDK: App crashing when trying to scroll through table

  I have a view controller with a table on it. When the app starts, it loads the first 5 visble cells. That works as expected.

• grabbing layer contents in a class

  - by Mike

  I have a custom UIImageView class that creates thumbnails (UIImageView) and each thumbnail has a label. The label is created by another class. The label class creates a UIImageView and a UITextView on top of it. This is the init object class' init method: - (id)initWithFrame:(CGRect)frame { if ([super initWithFrame:frame] == nil) { return nil; } CGRect myFrame = CGRectMake(0, 0, 100, 100); myLabel = [[myLabelClass alloc] initWithFrame: myFrame]; //myLabelClass is a UIImageView based class [myLabel setCenter:CGPointMake(50, 50)]; [self addSubview: myLabel]; return self; } So, I have this MAIN VIEW CONTROLLER | |___ UIImageView WITH LABEL | |____ label background (UIView) |____ UITEXTVIEW (text) Now I want to write the contents of all these 3 components to a quartz context. I need to write using drawInRect, because I need to write the full object to a precise location. I expected object.layer.contents to be the image equivalent to these 3 "layers" flattened, in other words, the object's image, the label background and the label text, as it would if I created these 3 objects in Photoshop and flatten the composition. I also expect object.myLabel.layer.contents to contains the rendered contents of the UITextView over the label background. The problem is that when I use UIImage *myImage = [UIImage imageWithCGImage:objecto.myLabel.layer.contents]; [myImage drawInRect:CGRectMake(0, 0, 100, 100)]; I get nothing. How can I obtain a "flattened" image resultant to the full object (including its subviews)? thanks

• How to access global variable in a view in Ruby on Rails?

  - by ben

  I have a User model. I have a Session controller, in which I have a global user variable that is assigned as follows: $user = User.authenticate(params[:session][:email], params[:session][:password]) (I've made user global just to try to solve this problem, so if there's a better way please let me know!) I need to use the email of the logged in user as a parameter to send to Flex part of my website. At the moment I'm creating the link as follows: <%= link_to "secondpage", secondpage_path(:email => @session.$user.email) But I'm getting the following error: compile error /Users/benhartney/rails_projects/talk/app/views/layouts/_header.html.erb:12: syntax error, unexpected tGVAR ..._path(:email = @session.$user.email) ).to_s); @output_buffe... There's also a little arrow pointing at $user If I remove the $ from $user, I get this error: undefined method `user' for nil:NilClass If I remove the (:email => @session.user.email) part, everything works fine, so I think all of the code except for this is ok. Can anyone tell me what I'm doing wrong? Thanks for reading!

• How can I tell when something outside my UITableViewCell has been touched?

  - by kk6yb

  Similar to this question I have a custom subclass of UITableViewCell that has a UITextField. Its working fine except the keyboard for doesn't go away when the user touches a different table view cell or something outside the table. I'm trying to figure out the best place to find out when something outside the cell is touched, then I could call resignFirstResponder on the text field. If the UITableViewCell could receive touch events for touches outside of its view then it could just resignFirstResponder itself but I don't see any way to get those events in the cell. The solution I'm considering is to add a touchesBegan:withEvent: method to the view controller. There I could send a resignFirstResponder to all tableview cells that are visible except the one that the touch was in (let it get the touch event and handle it itself). Maybe something like this pseudo code: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint touchPoint = // TBD - may need translate to cell's coordinates for (UITableViewCell* aCell in [theTableView visibleCells]) { if (![aCell pointInside:touchPoint withEvent:event]) { [aCell resignFirstResponder]; } } } I'm not sure if this is the best way to go about this. There doesn't seem to be any way for the tableviewcell itself to receive event notifications for events outside its view.

• Core Data confusion: fetch without tableview.

  - by Mr. McPepperNuts

  I have completed and reproduced Core Data tutorials using a tableview to display contents. However, I want to access an Entity through a fetch on a view without a tableview. I used the following fetch code, but the count returned is always 0. The data exists when the database is opened using SQLite tools. NSManagedObject *entryObj; XYZDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; NSManagedObjectContext *managedObjectContext = appDelegate.managedObjectContext; NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Quote" inManagedObjectContext:managedObjectContext]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"id" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [request setEntity: entity]; NSArray *results = [managedObjectContext executeFetchRequest:request error:nil]; if (results == nil) { NSLog(@"No results found"); entryObj = nil; }else { NSLog(@"results %d", [results count]); } [request release]; [sortDescriptors release]; count returned is always 0; it should be 5. Can anyone point me to a reference or tutorial regarding creating a controller not to be used with a tableview.

• How to handle checkboxes in ASP.NET MVC forms?

  - by Will

  This seems a bit bizarre to me, but as far as I can tell, this is how you do it. I have a collection of objects, and I want users to select one or more of them. This says to me "form with checkboxes." My objects don't have any concept of "selected" (they're rudimentary POCO's formed by deserializing a wcf call). So, I do the following: public class SampleObject{ public Guid Id {get;set;} public string Name {get;set;} } In the view: <% using (Html.BeginForm()) { %> <%foreach (var o in ViewData.Model) {%> <%=Html.CheckBox(o.Id)%>&nbsp;<%= o.Name %> <%}%> <input type="submit" value="Submit" /> <%}%> And, in the controller, this is the only way I can see to figure out what objects the user checked: public ActionResult ThisLooksWeird(FormCollection result) { var winnars = from x in result.AllKeys where result[x] != "false" select x; // yadda } Its freaky in the first place, and secondly, for those items the user checked, the FormCollection lists its value as "true false" rather than just true. Obviously, I'm missing something. I think this is built with the idea in mind that the objects in the collection that are acted upon within the html form are updated using UpdateModel() or through a ModelBinder. But my objects aren't set up for this; does that mean that this is the only way? Is there another way to do it?

• How to submit Nothing as a route value to ASP MVC

  - by Adam

  I have a route with several optional parameters. These are possible search terms in different fields. So, for example, if I have fields key, itemtype and text then I have in global.asax: routes.MapRoute( _ "Search", _ "Admin.aspx/Search/{Key}/{ItemType}/{Text}", _ New With {.controller = "Admin", .action = "Search" .Key = Nothing, .ItemType = Nothing, .Text = Nothing} _ ) My action takes optional parameters: Function Search(Optional ByVal Key As String = Nothing, _ Optional ByVal ItemType As Integer = 0, _ Optional ByVal Text As String = Nothing, _ Optional ByVal OtherText As String = Nothing) It then checks if the Key and Text strings have a non-null (and non-empty) value and adds search terms to the db request as needed. However, is it possible to send in a null value for, for example, Key but still send in a value for Text? If so, what does the URL look like? (Admin.aspx/Search//0/Foo doesn't work :) ) I know I can handle this using a parameter array instead, but wondered if this was possible using the sort of route described? I could of course define some other value as equivalent to null (for example, a space/%20) but is there any way to send a null value in the URL? I'm suspecting not, but thought I'd see if anyone knew of one. I'm using ASP MVC 2 for this project.

• How to call a function from another class file

  - by Guy Parker

  I am very familiar with writing VB based applications but am new to Xcode (and Objective C). I have gone through numerous tutorials on the web and understand the basics and how to interact with Interface Builder etc. However, I am really struggling with some basic concepts of the C language and would be grateful for any help you can offer. Heres my problem… I have a simple iphone app which has a view controller (FirstViewController) and a subview (SecondViewController) with associated header and class files. In the FirstViewController.m have a function defined @implementation FirstViewController (void) writeToServer:(const uint8_t ) buf { [oStream write:buf maxLength:strlen((char)buf)]; } It doesn't really matter what the function is. I want to use this function in my SecondViewController, so in SecondViewController.m I import FirstViewController.h import "SecondViewController.h" import "FirstViewController.h" @implementation SecondViewController -(IBAction) SetButton: (id) sender { NSString *s = [@"Fill:" stringByAppendingString: FillLevelValue.text]; NSString *strToSend = [s stringByAppendingString: @":"]; const uint8_t *str = (uint8_t *) [strToSend cStringUsingEncoding:NSASCIIStringEncoding]; FillLevelValue.text = strToSend; [FirstViewController writeToServer:str]; } This last line is where my problem is. XCode tells me that FirstViewController may not respond to writeToServer. And when I try to run the application it crashes when this function is called. I guess I don't fully understand how to share functions and more importantly, the relationship between classes. In an ideal world I would create a global class to place my functions in and call them as required. Any advice gratefully received.

• Alloy MVC Framework Titanium Network (Model)

  - by flyingDuck

  I'm trying to authenticate using the Model in Alloy. I have been trying to figure this problem out since yesterday. If anybody could help me, I'd really appreciate it. So, I have a view login.xml, then a controller login.js. The login.js contains the following function: var user = Alloy.Models.user; //my user.js model function login(e) { if($.username.value !== '' && $.password.value !== ''){ if(user.login($.username.value, $.password.value)){ Alloy.createController('home').getView().open(); $.login.close(); } }else{ alert('Username and/or Password required!'); } } Then in my user.js model, it's like this: extendModel : function(Model) { _.extend(Model.prototype, { login: function(username, password) { var first_name, last_name, email; var _this = this; var url = 'http://myurl.com/test.php'; var auth = Ti.Network.createHTTPClient({ onerror: function(e){ alert(e.error); }, onload: function(){ var json = this.responseText; var response = JSON.parse(json); if(response.logged == true){ first_name = response.f_name; last_name = response.l_name; email = response.email; _this.set({ loggedIn: 1, username: email, realname: first_name + ' ' + last_name, email: email, }); _this.save(); }else{ alert(response.message); } }, }); auth.open('POST', url); var params = { usernames: username, passwords: password, }; auth.send(params); alert(_this.get('email')); //alert email }, }); When I click on login in login.xml it calls the function login in index.js. So, now my problem is that, when I click the button for the first time, I get an empty alert from alert(_this.get('email')), but then when I click the button the second time, everything works fine, it alerts the email. I have no idea what's going on. Thank you for the help.

• Overriding content_type for Rails Paperclip plugin

  - by Fotios

  I think I have a bit of a chicken and egg problem. I would like to set the content_type of a file uploaded via Paperclip. The problem is that the default content_type is only based on extension, but I'd like to base it on another module. I seem to be able to set the content_type with the before_post_process class Upload < ActiveRecord::Base has_attached_file :upload before_post_process :foo def foo logger.debug "Changing content_type" #This works self.upload.instance_write(:content_type,"foobar") # This fails because the file does not actually exist yet self.upload.instance_write(:content_type,file_type(self.upload.path) end # Returns the filetype based on file command (assume it works) def file_type(path) return `file -ib '#{path}'`.split(/;/)[0] end end But...I cannot base the content type on the file because Paperclip doesn't write the file until after_create. And I cannot seem to set the content_type after it has been saved or with the after_create callback (even back in the controller) So I would like to know if I can somehow get access to the actual file object (assume there are no processors doing anything to the original file) before it is saved, so that I can run the file_type command on that. Or is there a way to modify the content_type after the objects have been created.

• Dynamically changing background color of a UIView

  - by EricM

  Hello- Here's my setup. I have a viewcontroller that I'm creating and adding as a subview. The viewcontroller presents some options that a user can chose from. The viewcontroller is being pushed in response to a "long press" gesture. Within the viewcontroller, I added a child UIView to group some other controls together so I can move them around the screen as a unit and, when they are displayed, center them on the location of the long press. Here is the code that instantiates the view controller, changes its location, and adds it as a subview: UserOptions *opts = [[UserOptions alloc] initWithNibName:@"UserOptions" bundle:nil]; [opts recenterOptions:location]; [self.view addSubview:opts.view]; That bit of code does create and push the viewcontroller, but the call to recenterOptions doesn't do anything. Here is that method: - (void) recenterOptions:(CGPoint)location { CGRect oldFrame = self.optionsView.frame; CGFloat newX = location.x; // + oldFrame.size.width / 2.0; CGFloat newY = location.y; // + oldFrame.size.height / 2.0; CGRect newFrame = CGRectMake(newX, newY, oldFrame.size.width, oldFrame.size.height); self.optionsView.frame = newFrame; } Note that self.optionsView is the child UIView that I added to the viewcontroller's nib. Does anyone know why I'm unable to change the location of the UIView? Regards, Eric

• Why isn't my UITableView appearing in the correct scroll position?

  - by zbrimhall

  I have a split view-based app that presents a master-detail interface, and uses a popover to present the master list when in portrait mode. The popover presents a sectioned table view that ultimately gets populated by a subclass of NSFetchedResultsController. I can tap the tool bar button to present the master list, scroll to whatever row, and tap the row to dismiss the popover. My problem is that if the table is scrolled past the top of the second section, when I dismiss the popover and then later tap the toolbar button to re-present it, the table's scroll position is always set such that the first row of the second section is at the top of the list. If I haven't scrolled past the top of the second section, it correctly remembers its scroll position when the table is presented again. Similarly, in landscape mode, if I scroll the table past the top of the third section and then rotate to portrait, when I come back to landscape the scroll position is always set such that the first row of the third section is at the top of the list. I tried calling -scrollToNearestSelectedRowAtScrollPosition:animated in both the master view controller's -viewWillAppear, as well as in the split view delegate's splitViewController:popoverController:willPresentViewController:, to no effect. Anybody have a clue what I might be doing wrong?

• Use interface between model and view in ASP.NET MVC

  - by Icerman

  Hi, I am using asp.net MVC 2 to develop a site. IUser is used to be the interface between model and view for better separation of concern. However, things turn to a little messy here. In the controller that handles user sign on: I have the following: IUserBll userBll = new UserBll(); IUser newUser = new User(); newUser.Username = answers[0].ToString(); newUser.Email = answers[1].ToString(); userBll.AddUser(newUser); The User class is defined in web project as a concrete class implementing IUser. There is a similar class in DAL implementing the same interface and used to persist data. However, when the userBll.AddUser is called, the newUser of type User can't be casted to the DAL User class even though both Users class implementing the interface (InvalidCastException). Using conversion operators maybe an option, but it will make the dependency between DAL and web which is against the initial goal of using interface. Any suggestions?

• collection_select not working as expected

  - by kgb

  First time I've come to use collection_select in a project and I've hit a wall with it. A Profile has_one Team, Team has_many Profile. In my view for editing profiles I have this. <td><%= f.collection_select(:team_id, @team, :id, :title) %></td> Which populates the drop down with titles of teams as expected. The couple of examples I have read seem to use it in a very similar way. I can't figure out when the profile is saved why it isn't populating the team_id field in my DB. In the development log the team_id is being passed. Processing ProfilesController#update (for 127.0.0.1 at 2010-03-28 22:49:16) [PUT] Parameters: {"commit"=>"Update", "profile"=>{"dob(1i)"=>"2010", "second_name"=>"", "dob(2i)"=>"3", "role"=>"", "dob(3i)"=>"28", "project"=>"", "specialties"=>"", "about"=>"", "team_id"=>"1", "status"=>"", "first_name"=>""}, "authenticity_token"=>"sdTiFPGj9JCO3OEge5EGNGxZbQSsq9ME5LP342EBjyc=", "id"=>"3"} The update controller is the standard scaffold one, this has worked fine for all other additions to the profile model I'd made previously. Am I missing something obvious?
