  • JQuery AJAX returned too much data that I had not requested

    - by kwokwai
    Hi all, I am using CakePHP 1.26 and CDN JQuery in this URL: http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js In a HTML web page, I have these lines of code: $.ajax({ type: "POST", url: "http://mywebsite.com/controllers/avail/"+curl, success: function(data) { alert(data);} }); and in the PHP page, I got another few lines of code: function avail($uname){ $result1=$this->Site1->User->findByusername($uname); if($result1){ return 1; } else{ return 0; } } As you see, the Avail function will return either zero or one. But there was some redundant data returned from the server, what I saw in the Alert box was somthing like this (rather than 0 or 1): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Missing Method in Controller</title> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <style type="text/css"> /* CSS Document */ /*PAGE LAYOUT*/ 0

  • Contacts & Autocomplete

    - by Vince
    First post. I'm new to android and programming in general. What I'm attempting to is to have an autocomplete text box pop up with auto complete names from the contact list. IE, if they type in "john" it will say "John Smith" or any john in their contacts. The code is basic, I pulled it from a few tutorials. private void autoCompleteBox() { ContentResolver cr = getContentResolver(); Uri contacts = Uri.parse("content://contacts/people"); Cursor managedCursor1 = cr.query(contacts, null, null, null, null); if (managedCursor1.moveToFirst()) { String contactname; String cphoneNumber; int nameColumn = managedCursor1.getColumnIndex("name"); int phoneColumn = managedCursor1.getColumnIndex("number"); Log.d("int Name", Integer.toString(nameColumn)); Log.d("int Number", Integer.toString(phoneColumn)); do { // Get the field values contactname = managedCursor1.getString(nameColumn); cphoneNumber = managedCursor1.getString(phoneColumn); if ((contactname != " " || contactname != null) && (cphoneNumber != " " || cphoneNumber != null)) { c_Name.add(contactname); c_Number.add(cphoneNumber); Toast.makeText(this, contactname, Toast.LENGTH_SHORT) .show(); } } while (managedCursor1.moveToNext()); } name_Val = (String[]) c_Name.toArray(new String[c_Name.size()]); phone_Val = (String[]) c_Number.toArray(new String[c_Name.size()]); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, name_Val); personName.setAdapter(adapter); } personName is my autocompletetextbox. So it actually works when I use it in the emulator (4.2) with manually entered contacts through the people app, but when I use it on my device, it will not pop up with any names. I'm sure it's something ridiculous but I've tried to find the answer and I'm getting nowhere. Can't learn if I don't ask.

  • wordpress php > div issue

    - by Philip Bateman
    Thanks in advance for you help Ive been doing this as a lovejob for friends and now im getting quotes of several hundred dollars for minor homepage variation and I'm not sure if its valid. I'm not a programmer myself, just trying hard :) Via the CafePress press75 theme, I'm trying to go from 1 / 2 / 3 column home layout, to 1-2 merged and 3, push the 2nd column data to the right and have the 1st column span as a 16:9 gallery (nextgengallery plugin installed). Is this really a complex thing from a coding perspective? The current guy talking to me is saying its going to cost $700 or 800 AUD to alter, which is rough when the template cost $85.. From this http://shocolate.com.au.previewdns.com/wp-content/uploads/2010/05/shocolatecurrent.jpg to this 'url+Shocolatelooklikethis.jpg' I was able to get the sidebar removed by taking out ‘‘ near the bottom of home.css.. Just can’t get the middle data to flow over it? This would be ideal as a result, as the system puts the latest selected blog post on the homepage, so if we can get rid of the sidebar div and have the text appear where it was, that would be ideal. Removing the sidebar from the bottom of home.php and setting the thumbnail width to say 450 gives me the result im after EXCEPT the text doesn’t fill where the sidebar is, it wraps underneath. Reference 'shocolate.com.au.previewdns.com' for current site Thank you!!! Phil (Melbourne)

  • What is the best way to do scoped finds based on access control rules in Rails?

    - by Rafael Szuminski
    Hi I need to find an elegant solution to scoped finds based on access control rules. Essentially I have the following setup: Users Customers AccessControl - Defines which user has access to another users data Users need to be able to access not just their own customers but also shared customers of other users. Obviously something like a simple association will not work: has_many :customers and neither will this: has_many :customers, :conditions => 'user_id in (1,2,3,4,5)' because the association uses with_scope and the added condition is an AND condition not an OR condition. I also tried overriding the find and method_missing methods with the association extension like this: has_many :customers do def find(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end def method_missing(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end end but the issue is that I don't have access to the user object / parent object inside the extension methods and it just does not work as planned. I also tried default_scope but as posted here before you can't pass a block to a default scope. Anyhow, I know that data segmentation and data access controls have been done before using rails and am wondering if somebody found an elegant way to do it. UPDATE: The AccessControl table has the following layout user_id shared_user_id The customer table has this structure: id account_id user_id first_name last_name Assuming the the following data would be in the AccessControl table: 1 1 1 3 1 4 2 2 2 13 and so on... And the account_id for user 1 is 13 I need to be able to retrieve customers that can be best described with the following sql statement: select * from customers where (account_id = 13 and user_id = null) or (user_id in (1,3,4))

  • Dynamic editor upload into web page. Need advice

    - by Andrew Florko
    Hello everybody, I am writing intranet site for tracking employees science activities in organization. There lots of editable information on each personal page (science degree, publications & so on) so I upload editor per request (user clicks "edit" and modal dialog with html editor: set of textboxes/comboboxes/autocomplete features & validation logic appears). Editor is html layout that is wrapped with jquery dialog plugin + some logic, written as javascript functions that should be invoked from the callee page (onsubmit, validate, afterLoad editor events). There are also attributes (editor preferrable with and height) that are passed to callee page also. Currently I send these functions & attribute as ... function onsubmit() { }; function validate() { } var width = 640; var height = 800 ... code that is embedded into the request page. Function calls and editor markup wrap with jquery plugin completed in the callee page. It works, but I have some try { call editor event handler } catch { } stuff in callee page (because not every editor provides these functions) and some attributes (editor width & height for instance) that are loaded as variables declared in javascript. Please, suggest, is there a better approach to build & use custom editors for my situation. Thank you in advance!

  • Should frontend and backend be handled by different controllers?

    - by DR
    In my previous learning projects I always used a single controller, but now I wonder if that is good practice or even always possible. In all RESTful Rails tutorials the controllers have a show, an edit and an index view. If an authorized user is logged on, the edit view becomes available and the index view shows additional data manipulation controls, like a delete button or a link to the edit view. Now I have a Rails application which falls exactly into this pattern, but the index view is not reusable: The normal user sees a flashy index page with lots of pictures, complex layout, no Javascript requirement, ... The Admin user index has a completly different minimalistic design, jQuery table and lots of additional data, ... Now I'm not sure how to handle this case. I can think of the following: Single controller, single view: The view is split into two large blocks/partials using an if statement. Single controller, two views: index and index_admin. Two different controllers: BookController and BookAdminController None of these solutions seems perfect, but for now I'm inclined to use the 3rd option. What's the preferred way to do this?

  • Quick questions re moving to InfoPath forms

    - by sweissman
    Hi there: I’ve been asked to look into how best to move forms into InfoPath and have a couple of basic questions about your experiences so I can get an insider’s lay of the land. Even some short, quick bullets would be really helpful -- thank you! Are you starting from scratch in InfoPath, or are you converting from paper or a different e-format? (Jetform, PDF, etc.) Are you trying to re-create the layout of a specific paper form, or is a regular online form OK? (trying to learn what the latest thinking is about this) Do you need only simple fill and submit capabilities, or do you need programming for calculations, validation, database lookup/entry/reporting, etc. as well? (don’t know how much harder it is to do all this vs. not) How long does each form take to finish? (I know it depends, but is there a rough guideline for planning purposes?) Who’s doing the actual work? (by title or function) What is especially straightforward or challenging about moving to InfoPath forms? (forewarned is forearmed!)

  • Clearing block affects wrong floating

    I've got two-column layout <div class="left-pane"> Left pane </div> <div class="central-pane"> <div> <ul class="customers-types-tabs"> <li>item 1</li> <li>item 2</li> <li>item 3</li> </ul> </div> <div>Main content</div> </div> and the stylesheet: .left-pane { width: 248px; float: left; background-color: #f6f6f6; border: 1px solid #e6e6e6; padding: 20px 5px; } .central-pane { margin-left: 270px; } .customers-types-tabs li { background-color: #f6f6f6; border: 1px solid #d5d5d5; line-height: 38px; padding: 0 20px; float: left; margin-right: 10px; position: relative; top: 1px; } The problem is that I want "Main content" to appear right below the div with ul inside it (that represents tabs control), but if I set Main content's div's style to clear: both, it appears below the left pane, which is taller than the ul. What should I do to get correct position of main content?

  • css absolute positioning hidden scrollbars ... with a twist

    - by ScottE
    I'm working on a website that targets 1024 X 768 as the minimum resolution. So, we're at about 970px wide. Design came back with an interesting layout that has a centered site with a banner that actually exceeds this width (1288px to be exact) that will look good for users with greater resolution, but look fine at 1024. So, to prevent scrollbars from showing up for those at 1024 I positioned the banner absolutely and used overflow-x: hidden on the body. This works just fine across our target browsers. Now, the client has come back and asked for scrollbars to be present for users on 800 X 600 (yes, this is not the target) so they can see a critical login button. How can this be accommodated for those 2% of their users without making radical changes? All I can think of is to detect their screen width and remove the overflow-x:hidden. You have to love when requirements change late in the build process! Edit - here's what I have that seems simple enough to me - any caveats here? if (screen.width === 800) { $("body").css("overflow-x", "visible"); }

  • Prawn image position

    I'm trying to layout 6 images per page with prawn in Ruby: case (idx % 6) # ugly when 0 : (pdf.start_new_page; pdf.image img, :position => :left, :vposition => :top, :width => 270) when 1 : pdf.image img, :position => :right, :vposition => :top, :width => 270 when 2 : pdf.image img, :position => :left, :vposition => :center, :width => 270 when 3 : pdf.image img, :position => :right, :vposition => :center, :width => 270 when 4 : pdf.image img, :position => :left, :vposition => :bottom, :width => 270 when 5 : pdf.image img, :position => :right, :vposition => :bottom, :width => 270 end Not sure what I'm doing wrong, but it prints the first 3 images to the PDF, then creates a new page and prints the last three: Page 1: <img> <img> <blank> <blank> <blank> <blank> Page 2: <blank> <blank> <blank> <img> <img> <img> Any suggestions would help.

  • How do I add an extra separator to the top of a UITableView?

    - by richt
    Hi, I have a view for the iPhone that is basically split in two, with an informational display in the top half, and a UITableView for selecting actions in the bottom half. The problem is that there is no border or separator above the first cell in the UITableView, so the first item in the list looks funny. How can I add an extra separator at the top of the table, to separate it from the display area above it? Here's the code to build the cells - it's pretty straightforward. The overall layout is handled in a xib. - (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]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } switch(indexPath.row) { case 0: { cell.textLabel.text = @"Action 1"; break; } case 1: { cell.textLabel.text = @"Action 2"; break; } // etc....... } return cell; }

  • Android ProgressDialog inside another dialog

    - by La bla bla
    I'm working on a game using AndEngine, and I need to show the users the list of his Facebook friends. I've created my custom Adatper and after the loading finishes everything works great. I have a problem with the loading it self. The ListView is inside a custom dialog, since I don't really know how to create one using AndEngine, So inside this dialog, I'm running an AsyncTask to fetch the friends' info, in that AsyncTask I'm have a ProgressDialog. The problem is, the ProgressDialog shows up behind the dialog that contains the to-be list (which while loading, is just the title). I can see the ProgressDialog "peeking" behind that dialog.. Any Ideas? Here's some code: FriendsDialog.java private ProgressDialog dialog; //Constructor of the AsyncTask public FriendsLoader(Context context) { dialog = new ProgressDialog(context); dialog.setMessage("Please wait..\nLoading Friends List."); } @Override protected void onPreExecute() { dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); dialog.setView(inflater.inflate(R.layout.loading, null)); dialog.setMessage("Please wait..\nLoading friends."); dialog.show(); } @Override protected void onPostExecute(ArrayList<HashMap<String, Object>> data) { if (dialog.isShowing()) { dialog.dismiss(); } MyAdapter myAdapter = new MyAdapter(context, data); listView = (ListView) findViewById(R.id.list); listView.setAdapter(myAdapter); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) { String id = (String) listView.getItemAtPosition(myItemInt); listener.onUserSelected(id); dismiss(); } }); }

  • Getting an updated location in Android

    - by jul
    Hi, I'm using the code shown below to get an updated value for location every time a button is clicked. When my activity is resumed I get an update every second, so that when I call getLastKnownLocation I expect to have a location that have been updated in the last second. Is that the correct way to do that? I would expect the onLocationChanged event to be triggered every time I execute a 'geo fix' command (or max after 1s since I request update every 1s), but it's only triggered the first time. Why? Any help/suggestion welcome! Thanks package org.digitalfarm.atable; ... public class Atable extends Activity { private Button mSearchButton; private TextView mytext; private LocationManager locationManager; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mSearchButton = (Button)this.findViewById(R.id.button); mytext = (TextView) findViewById(R.id.dude); locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); final Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); mSearchButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { String provider = locationManager.getBestProvider(criteria, true); Location location = locationManager.getLastKnownLocation(provider); } }); } //Start a location listener LocationListener onLocationChange=new LocationListener() { public void onLocationChanged(Location loc) { //sets and displays the lat/long when a location is provided String latlong = "Lat: " + loc.getLatitude() + " Long: " + loc.getLongitude(); mytext.setText(latlong); } public void onProviderDisabled(String provider) { // required for interface, not used } public void onProviderEnabled(String provider) { // required for interface, not used } public void onStatusChanged(String provider, int status, Bundle extras) { // required for interface, not used } }; //pauses listener while app is inactive @Override public void onPause() { super.onPause(); locationManager.removeUpdates(onLocationChange); } //reactivates listener when app is resumed @Override public void onResume() { super.onResume(); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,100.0f,onLocationChange); } }

  • avoiding code duplication in Rails 3 models

    - by Dustin Frazier
    I'm working on a Rails 3.1 application where there are a number of different enum-like models that are stored in the database. There is a lot of identical code in these models, as well as in the associated controllers and views. I've solved the code duplication for the controllers and views via a shared parent controller class and the new view/layout inheritance that's part of Rails 3. Now I'm trying to solve the code duplication in the models, and I'm stuck. An example of one of my enum models is as follows: class Format < ActiveRecord::Base has_and_belongs_to_many :videos attr_accessible :name validates :name, presence: true, length: { maximum: 20 } before_destroy :verify_no_linked_videos def verify_no_linked_videos unless self.videos.empty? self.errors[:base] << "Couldn't delete format with associated videos." raise ActiveRecord::RecordInvalid.new self end end end I have four or five other classes with nearly identical code (the association declaration being the only difference). I've tried creating a module with the shared code that they all include (which seems like the Ruby Way), but much of the duplicate code relies on ActiveRecord, so the methods I'm trying to use in the module (validate, attr_accessible, etc.) aren't available. I know about ActiveModel, but that doesn't get me all the way there. I've also tried creating a common, non-persistent parent class that subclasses ActiveRecord::Base, but all of the code I've seen to accomplish this assumes that you won't have subclasses of your non-persistent class that do persist. Any suggestions for how best to avoid duplicating these identical lines of code across many different enum models?

  • UML diagrams that are actually pretty?

    - by Borek
    I'm looking for a diagramming software that would produce good looking output. It doesn't need to support everything (or even much) from UML, is doesn't need to have code engineering functions or anything, it just needs to produce visually interesting output. Here is a couple of samples of products that I consider ugly / not good enough: Visio with default UML stencils (didn't find better looking ones), Enterprise Architect, Dia, ArgoUML and many other "professional" UML tools. A couple of visually compelling tools that I considered (but found issues with): Visual Studio class diagrams - just for .NET classes but the output is miles better than what UML tools typically produce NClass - similar to VS's class diagrams but I could not find the "pretty", blue skin anywhere yuml.me - very nice but lacking some advanced layout options. I have to say that I find their style almost ideal for high-level diagrams - they look sketchy which is good. Balsamiq - I think Joel used this for hginit.com and I liked it. However, it's not suited for creating software diagrams so I can imagine it would be quite a lot of work MS Word has actually quite a good graphics engine but I'd rather leave this as a choice of the last resort I'd be grateful for any good tips.

  • Dismiss android activity displayed as Popup

    - by Sit
    So i have a service, that starts an activity displayed as a Popup thank's to "android:style/Theme.Dialog" This Activity shows a Listview, with a list of application. On each element of the listview, there is a short description of the application, and two buttons. 1 for launching the application 2 for displaying a toast with more informations. Here is the code in my service : it starts the activity Intent intent = new Intent(this, PopUpActivity.class); intent.addFlags(Intent.FLAG_DEBUG_LOG_RESOLUTION); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); getApplicationContext().startActivity(intent); this activity uses a custom layout, with a listview, adapted with a custom ArrayAdapter In this adaptater, i've put an action on the start button in order to start the current application Button lanceur = (Button) v.findViewById(R.id.Buttonlancer); lanceur.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { p.start(mcontext); } }); with p.start, i start the application. But now, if i press "back" from the application, i go back to the popup... and i can start another application. I don't want it to be possible. That's why i wish i could dismiss/destroy/finish my PopupActivity, but i can't manage to do it with the code i have.

  • Relatively simple task: How do I pass back the selected item from one activity to another?

    - by Brian D
    I have two activities: one displays an image and a button, the other displays a photo gallery. I want to be able to select any of the images in the gallery and then display them on the first activity in place of the default image. public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.gallery); Gallery g = (Gallery) findViewById(R.id.gallery); g.setAdapter(new ImageAdapter(this)); g.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView parent, View v, int position, long id) { Toast.makeText(PhotoGallery.this, "Position: " + id, Toast.LENGTH_SHORT).show(); Intent intent=new Intent(); intent.putExtra("PictureID", position); setResult(RESULT_OK, intent); finish(); } }); } Am I even close here? I'm not quite sure what to do with any string or int I would attach to the Intent -- can I attach the object itself? I'd much rather pass back at minimum the string name of the resource (image), but the only thing I can seem to figure out right now is how to pass back the position of the picture ... not a great solution. I can clarify more if necessary -- thanks.

  • iOS6: do we have to set rootViewController in App delegate in order to support different orientations?

    - by Centurion
    The app was perfectly fine working in iOS5 in landscape orientation. However in iOS6, it started to use portrait orientation in all view controllers. The methods shouldAutorotateToInterfaceOrientation are not called anymore. I read the new stuff about changed rotation mechanism in iOS6 and I was able to fix that by adding a line in my AppDelegate: self.window.rootViewController = _viewController _viewControler is the starting screen (Home-menu). All other view controllers implement shouldAutorotateToInterfaceOrientation method and returns YES for landscape orientations only. So, it's perfectly working solution for the app that needs to support only one orientation. However, the problem is I need one view controller (lets call it phone-VC) to be presented in portrait orientation. Now, if I want this view controller would be rotated then I need to return YES in Home-menu controller that is assigned to rootViewControler in appDelegate. However, I can't do that because this rootViewController is starting window that need to presented in landscape only, otherwise the layout with graphics in this window will break. But if I don't return YES from its shouldAutorotateToInterfaceOrientation (Home-menu) then the same method is not called in my view phone-VC that needs to be presented in portrait. Any ideas? Does the assignation of rootViewController is mandatory in AppDelegate? UPDATE: the problem exists on device (at least on iPhone4).

  • tbody td borders not scrolling with content in tbody overflow:auto;

    - by tester
    I am unable to get the borders of these td's to follow their rows as I scroll through this overflow:auto; . Any ideas on a fix? Note: Setting table-layout:fixed or making rows display:block isn't an option as the rows will lose their fluidity.. You can see the issue in the latest Firefox, so I assume it's messed up elsewhere. Here is a test I setup (scroll to the bottom for the demo): http://www.webdevout.net/test?01y HTML: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en"> <head> <title>Test</title> </head> <body> <table> <thead><th>One</th><th>Two</th><th>Three</th></thead> <tbody> <tr><td>Item</td><td>Item</td><td>Item</td></tr> <tr><td>Item</td><td>Item</td><td>Item</td></tr> <tr><td>Item</td><td>Item</td><td>Item</td></tr> <tr><td>Item</td><td>Item</td><td>Item</td></tr> </tbody> </table> </body> </html> CSS: table {width:100%;border-collapse:collapse;} tbody {height:200px;overflow:auto;} td {border-bottom:1px solid #f00;}

  • C# function called after dependency property have been set

    - by mizipzor
    My code currently looks like this: private Foo myFoo; public Foo CurrentFoo { get { return myFoo; } set { SetFoo(value); } } private void SetFoo(Foo newFoo) { // Do stuff // Here be dragons myFoo = newFoo; } To be able to bind it in XAML/WPF I need to turn Foo into a dependency property: public static DependencyProperty CurrentFooProperty = DependencyProperty.Register("CurrentFoo", typeof(Foo), typeof(FooHandler), new PropertyMetadata(false)); public Foo CurrentFoo { get { return (Foo)GetValue(CurrentFooProperty); } set { SetValue(CurrentFooProperty, value); } } Ive heard that you shouldnt do magic inside the actual C# property set {}, since it might not be called but the value is written directly to the dependency property. If this is false, let me know, it seems like the most obvious and simple route to take. I know I can add a validation function to the dependency property but I assume that it shouldnt be used for this? I need to communicate the change to legacy systems that cannot yet be bound in XAML. Whats the best way to approach this problem?
