  • Spam proof hit counter in Django

    - by Jim Robert
    I already looked at the most popular Django hit counter solutions and none of them seem to solve the issue of spamming the refresh button. Do I really have to log the IP of every visitor to keep them from artificially boosting page view counts by spamming the refresh button (or writing a quick and dirty script to do it for them)? More information So right now you can inflate your view count with the following few lines of Python code. Which is so little that you don't even really need to write a script, you could just type it into an interactive session: from urllib import urlopen num_of_times_to_hit_page = 100 url_of_the_page = "http://example.com" for x in range(num_of_times_to_hit_page): urlopen(url_of_the_page) Solution I'll probably use To me, it's a pretty rough situation when you need to do a bunch of writes to the database on EVERY page view, but I guess it can't be helped. I'm going to implement IP logging due to several users artificially inflating their view count. It's not that they're bad people or even bad users. See the answer about solving the problem with caching... I'm going to pursue that route first. Will update with results. For what it's worth, it seems Stack Overflow is using cookies (I can't increment my own view count, but it increased when I visited the site in another browser.) I think that the benefit is just too much, and this sort of 'cheating' is just too easy right now. Thanks for the help everyone!

  • ArrayIndexOutOfBoundsException with custom Android Adapter for multiple views in ListView

    - by Dan Watling
    I am attempting to create a custom Adapter for my ListView since each item in the list can have a different view (a link, toggle, or radio group), but when I try to run the Activity that uses the ListView I receive an error and the app stops. The application is targeted for the Android 1.6 platform. The code: public class MenuListAdapter extends BaseAdapter { private static final String LOG_KEY = MenuListAdapter.class.getSimpleName(); protected List<MenuItem> list; protected Context ctx; protected LayoutInflater inflater; public MenuListAdapter(Context context, List<MenuItem> objects) { this.list = objects; this.ctx = context; this.inflater = (LayoutInflater)this.ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public View getView(int position, View convertView, ViewGroup parent) { Log.i(LOG_KEY, "Position: " + position + "; convertView = " + convertView + "; parent=" + parent); MenuItem item = list.get(position); Log.i(LOG_KEY, "Item=" + item ); if (convertView == null) { convertView = this.inflater.inflate(item.getLayout(), null); } return convertView; } @Override public boolean areAllItemsEnabled() { return false; } @Override public boolean isEnabled(int position) { return true; } @Override public int getCount() { return this.list.size(); } @Override public MenuItem getItem(int position) { return this.list.get(position); } @Override public long getItemId(int position) { return position; } @Override public int getItemViewType(int position) { Log.i(LOG_KEY, "getItemViewType: " + this.list.get(position).getLayout()); return this.list.get(position).getLayout(); } @Override public int getViewTypeCount() { Log.i(LOG_KEY, "getViewTypeCount: " + this.list.size()); return this.list.size(); } } The error I receive: java.lang.ArrayIndexOutOfBoundsException at android.widget.AbsListView$RecycleBin.addScrapView(AbsListView.java:3523) at android.widget.ListView.measureHeightOfChildren(ListView.java:1158) at android.widget.ListView.onMeasure(ListView.java:1060) at android.view.View.measure(View.java:7703) I do know that the application is returning from getView and everything seems in order. Any ideas on what could be causing this would be appreciated. Thanks, -Dan

  • ASP .NET MVC partial views and routing

    - by Johnny
    Hi, I have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller, or if this even possible at all! Thanks!

  • Difficulty with apps with a forced landscape orientation

    - by mahboudz
    I have two apps, both of which force the user to use the iPhone in landscape mode, in order to have a wider screen, instead of a taller one. One of the things I have found is that my first view will look fine, but all other views come up with their subviews (UIButtons, UIPicker, UIViews) squeezed to one side or clipped (depending on whether the elements were set to move, resize or stay in the same position as the view size changed). All my views are designed in IB in the landscape orientation. My underlying UIWindow, and everything I can think of has been laid out in landscape orientation. Even my plist file has the UIInterfaceOrientationLandscapeRight flag set. Now, if I load all my views at the same time as my rootview controller, then I have no problems. But if I have views loaded later, they get clipped or squeezed. The only way to get around the problem was to add the following line in my code that flips in a new view: [coming.view setFrame:CGRectMake(0, 0, 480, 300)]; Anyone know why I need to do this? Is it just that the iPhone assumes that loaded views are 300x480 unless a transform gets applied to them? Thanks. ps. This is what the view looks like if I don't call setFrame, as described above: All viewcontrollers that get loaded after the first one will have their screen similarly squeezed down. For some reason the first viewcontroller doesn't have this issue.

  • Key event handling process

    - by backspace7
    I'd like to know how the key event is handled in Android platform. From 'when user type key 'a' on software keyboard', To 'view draw the character 'a' on itself'. Probably, the key event is generated by IME, And it will be sent to parent view, Finally, view(such as EditText) displays chracters. Please somebody explains about these entire key event handling process.

  • XMLBeans - xsi:type stripped using Axis2 and Tomcat?

    - by Matthew Gamble
    I’m new to XMLBeans and have been trying to use it to create an XML document as part of an axis2 web service. When I run my code as a standard Java application or as a standard servlet, the XML is correctly generated: <?xml version="1.0" encoding="UTF-8"?> <c:BroadsoftDocument protocol="OCI" xmlns:c="C"> <sessionId>000000001</sessionId> <command xsi:type="AuthenticationRequest" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <userId>admin</userId></command> </c:BroadsoftDocument> However, when the exact same code is run under Axis2 & Tomcat in a servlet I get: <?xml version="1.0" encoding="UTF-8"?> <c:BroadsoftDocument protocol="OCI" xmlns:c="C"> <sessionId>000000001</sessionId> <command> <userId>admin</userId></command> </c:BroadsoftDocument> This of course isn’t valid – the xsi:type of the “command” element is stripped when the code is run under Tomcat. Does anyone have any suggestions of what I could be doing wrong that would cause this type of issue only when running under Axis2? At first I thought it was a Tomcat issue, but after creating a generic servlet and running the exact same code I don't have any issues. I've tried playing with the XMLOptions for XMLBeans, but couldn't seem to resolve the problem. The options I'm currently using are: xmlOptions = new XmlOptions(); xmlOptions.setCharacterEncoding("UTF-8"); xmlOptions.setUseDefaultNamespace(); xmlOptions.setSaveAggressiveNamespaces(); xmlOptions.setSavePrettyPrint();

  • Determing size of visible area of a ScrollingGraphicalViewer in Eclipse GEF

    - by Simon
    I am attempting to create a simple application using Eclipse GEF that displays a diagram inside a ScrollingGraphicalViewer. On start-up I want the diagram to be centered inside the viewer (imagine a star layout where the center of the star is in the center of the view). Here are what I think are the relevant code sections: My view: public class View extends ViewPart { public static final String ID = "GEFProofOfConcept.view"; ... public void createPartControl(Composite parent) { viewer.createControl(parent); viewer.setRootEditPart(rootEditPart); viewer.setEditPartFactory(editPartFactory); viewer.setContents(DummyModelCreator.generateModel()); } The edit part code: @Override protected void refreshVisuals() { Project project = (Project) getModel(); // This is where the actual drawing is done, // Simply a rectangle with text Rectangle bounds = new Rectangle(50, 50, 75, 50); getFigure().setBounds(bounds); Label label = new Label(project.getName()); projectFont = new Font(null, "Arial", 6, SWT.NORMAL); label.setFont(projectFont); label.setTextAlignment(PositionConstants.CENTER); label.setBounds(bounds.crop(IFigure.NO_INSETS)); getFigure().add(label); setLocation(); } private void setLocation() { Project project = (Project) getModel(); if (project.isRoot()) { // Place in centre of the layout Point centrePoint = new Point(0, 0); // This is where I need the center of the view getFigure().setLocation(centrePoint); } else { ... } } And the parent of the above edit part: public class ProjectDependencyModelEditPart extends AbstractGraphicalEditPart { @Override protected IFigure createFigure() { Figure f = new FreeformLayer(); f.setLayoutManager(new XYLayout()); return f; } ... Alternative solutions to the problem also welcome, I am most certainly a GEF (and Eclipse in general) newbie.

  • Qt4: QPrinter / QPainter only prints the first document

    - by hurikhan77
    The problem is that my application only prints the first document fine. The second document is empty, only the page number is printed, the rest of the page is empty. In Qt4, I'm initializing the printer in the main.cpp in the following way: mw->printer = new QPrinter(QPrinter::HighResolution); mw->printer->setPaperSize(QPrinter::A5); mw->printer->setNumCopies(2); mw->printer->setColorMode(QPrinter::GrayScale); QPrintDialog *dialog = new QPrintDialog(mw->printer, mw); dialog->setWindowTitle(QObject::tr("Printer Setup")); if (dialog->exec() == QDialog::Accepted) { mw->printer->setFullPage(TRUE); return a.exec (); } This works fine for printing the first document from the application: qDebug("Printing"); QPainter p; if (!p.begin(printer)) { qDebug("Printing aborted"); return; } Q3PaintDeviceMetrics metrics(p.device()); int dpiy = metrics.logicalDpiY(); int dpix = metrics.logicalDpiX(); int tmargin = (int) ((marginTop / 2.54) * dpiy); int bmargin = (int) ((marginBottom / 2.54) * dpiy); int lmargin = (int) ((marginLeft / 2.54) * dpix); int rmargin = (int) ((marginRight / 2.54) * dpix); QRect body(lmargin, tmargin, metrics.width() - (lmargin + rmargin), metrics.height() - (tmargin + bmargin)); QString document; /* ... app logic to write a richtext document */ Q3SimpleRichText richText(QString("<qt>%1</qt>").arg(document), QFont("Arial", fontSize)); richText.setWidth(&p, body.width()); QRect view(body); int page = 1; do { // draw text richText.draw(&p, body.left(), body.top(), view, colorGroup()); view.moveBy(0, body.height()); p.translate(0, -body.height()); // insert page number p.drawText(view.right() - p.fontMetrics().width(QString::number(page)), view.bottom() + p.fontMetrics().ascent() + 5, QString::number(page)); // exit loop on last page if (view.top () >= richText.height ()) break; printer->newPage(); page++; } while (TRUE); if (!p.end()) qDebug("Print painter yielded failure"); But when this routine runs the second time, it does not print the document. It will just print an empty page but still with the page number on it. This worked fine before with Qt3.

  • Custom NSView in NSMenuItem not receiving mouse events

    - by Dennis
    I have an NSMenu popping out of an NSStatusItem using popUpStatusItemMenu. These NSMenuItems show a bunch of different links, and each one is connected with setAction: to the openLink: method of a target. This arrangement has been working fine for a long time. The user chooses a link from the menu and the openLink: method then deals with it. Unfortunately, I recently decided to experiment with using NSMenuItem's setView: method to provide a nicer/slicker interface. Basically, I just stopped setting the title, created the NSMenuItem, and then used setView: to display a custom view. This works perfectly, the menu items look great and my custom view is displayed. However, when the user chooses a menu item and releases the mouse, the action no longer works (i.e., openLink: isn't called). If I just simply comment out the setView: call, then the actions work again (of course, the menu items are blank, but the action is executed properly). My first question, then, is why setting a view breaks the NSMenuItem's action. No problem, I thought, I'll fix it by detecting the mouseUp event in my custom view and calling my action method from there. I added this method to my custom view: - (void)mouseUp:(NSEvent *)theEvent { NSLog(@"in mouseUp"); } No dice! This method is never called. I can set tracking rects and receive mouseEntered: events, though. I put a few tests in my mouseEntered routine, as follows: if ([[self window] ignoresMouseEvents]) { NSLog(@"ignoring mouse events"); } else { NSLog(@"not ignoring mouse events"); } if ([[self window] canBecomeKeyWindow]) { dNSLog((@"canBecomeKeyWindow")); } else { NSLog(@"not canBecomeKeyWindow"); } if ([[self window] isKeyWindow]) { dNSLog((@"isKeyWindow")); } else { NSLog(@"not isKeyWindow"); } And got the following responses: not ignoring mouse events canBecomeKeyWindow not isKeyWindow Is this the problem? "not isKeyWindow"? Presumably this isn't good because Apple's docs say "If the user clicks a view that isn’t in the key window, by default the window is brought forward and made key, but the mouse event is not dispatched." But there must be a way do detect these events. HOW? Adding: [[self window] makeKeyWindow]; has no effect, despite the fact that canBecomeKeyWindow is YES.

  • where to set wait cursor in long operation in MVP pattern?

    - by Benny
    For a long operation that will be executed in presenter, where to set the wait cursor? in View? the view shouldn't know too much about business logic, it is passive. in presenter? seems odd in presenter to call UI code. add method to View interface, like SetWait(bool), and call it in presenter? So what do you think?

  • Asp.Net MVC - Blank model not returning blank data

    - by Pino
    I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action. [HttpPost] public ActionResult Manage(ProductOptionModel DataToAdd) { if (!ModelState.IsValid) { return View(DataToAdd); } var ProdServ = new ProductService(); if (DataToAdd.ID != 0) { //Edit Mode. DataToAdd = ProdServ.EditProductOption(DataToAdd); ViewData["Message"] = "Option Changes Made"; }else { //Add DataToAdd = ProdServ.AddProductOption(DataToAdd); ViewData["Message"] = "New Option Added"; } var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID}; return View(RetModel); } So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. Any ideas why? I have debugged the code and checked that the RetModel variable is empty.

  • Data in two databases, eager spool resulting in query

    - by Valkyrie
    I have two databases in SQL2k5: one that holds a large amount of static data (SQL Database 1) (never updated but frequently inserted into) and one that holds relational data (SQL Database 2) related to the static data. They're separated mainly because of corporate guidelines and business requirements: assume for the following problem that combining them is not practical. There are places in SQLDB2 that PKs in SQLDB1 are referenced; triggers control the referential integrity, since cross-database relationships are troublesome in SQL Server. BUT, because of the large amount of data in SQLDB1, I'm getting eager spools on queries that join from the Id in SQLDB2 that references the data in SQLDB1. (With me so far? Maybe an example will help:) SELECT t.Id, t.Name, t2.Company FROM SQLDB1.table t INNER JOIN SQLDB2.table t2 ON t.Id = t2.FKId This query results in a eager spool that's 84% of the load of the query; the table in SQLDB1 has 35M rows, so it's completely choking this query. I can't create a view on the table in SQLDB1 and use that as my FK/index; it doesn't want me to create a constraint based on a view. Anyone have any idea how I can fix this huge bottleneck? (Short of putting the static data in the first db: believe me, I've argued that one until I'm blue in the face to no avail.) Thanks! valkyrie Edit: also can't create an indexed view because you can't put schemabinding on a view that references a table outside the database where the view resides. Dang it.

  • DTGridView losing content while scrolling

    - by Wim Haanstra
    I am using DTGridView from the DTKit by Daniel Tull. I implemented it in a very simple ViewController and the test I am doing is to place a button in the last row of the grid, which should add another row to the grid (and therefor moving the button to a row beneath it). The problem is, when I click the button a couple of times and then start scrolling, the grid seems to lose its content. As I am not completly sure this is a bug in the grid, but more in my code, I hope you guys can help me out and track down the bug. First I have my header file, which is quite simple, because this is a test: #import <UIKit/UIKit.h> #import "DTGridView.h" @interface TestController : UIViewController <DTGridViewDelegate, DTGridViewDataSource> { DTGridView* thumbGrid; } @end I declare a DTGridView, which will be my grid, where I want to put content in. Now, my code file: #import "TestController.h" @implementation TestController int rows = 1; - (NSInteger)numberOfRowsInGridView:(DTGridView *)gridView { return rows; } - (NSInteger)numberOfColumnsInGridView:(DTGridView *)gridView forRowWithIndex:(NSInteger)index { if (index == rows - 1) return 1; else return 3; } - (CGFloat)gridView:(DTGridView *)gridView heightForRow:(NSInteger)rowIndex { return 57.0f; } - (CGFloat)gridView:(DTGridView *)gridView widthForCellAtRow:(NSInteger)rowIndex column:(NSInteger)columnIndex { if (rowIndex == rows - 1) return 320.0f; else return 106.6f; } - (DTGridViewCell *)gridView:(DTGridView *)gridView viewForRow:(NSInteger)rowIndex column:(NSInteger)columnIndex { DTGridViewCell *view = [[gridView dequeueReusableCellWithIdentifier:@"thumbcell"] retain]; if (!view) view = [[DTGridViewCell alloc] initWithReuseIdentifier:@"thumbcell"]; if (rowIndex == rows - 1) { UIButton* btnLoadMoreItem = [[UIButton alloc] initWithFrame:CGRectMake(10, 0, 301, 57)]; [btnLoadMoreItem setTitle:[NSString stringWithFormat:@"Button %d", rowIndex] forState:UIControlStateNormal]; [btnLoadMoreItem.titleLabel setFont:[UIFont boldSystemFontOfSize:20]]; [btnLoadMoreItem setBackgroundImage:[[UIImage imageNamed:@"big-green-button.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal]; [btnLoadMoreItem addTarget:self action:@selector(selectLoadMoreItems:) forControlEvents:UIControlEventTouchUpInside]; [view addSubview:btnLoadMoreItem]; [btnLoadMoreItem release]; } else { UILabel* label = [[UILabel alloc] initWithFrame:CGRectMake(10,0,100,57)]; label.text = [NSString stringWithFormat:@"%d x %d", rowIndex, columnIndex]; [view addSubview:label]; [label release]; } return [view autorelease]; } - (void) selectLoadMoreItems:(id) sender { rows++; [thumbGrid setNeedsDisplay]; } - (void)viewDidLoad { [super viewDidLoad]; thumbGrid = [[DTGridView alloc] initWithFrame:CGRectMake(0,0, 320, 320)]; thumbGrid.dataSource = self; thumbGrid.gridDelegate = self; [self.view addSubview:thumbGrid]; } - (void)viewDidUnload { [super viewDidUnload]; } - (void)dealloc { [super dealloc]; } @end I implement all the methods for the DataSource, which seem to work. The grid is filled with as many rows as my int 'rows' ( +1 ) has. The last row does NOT contain 3 columns, but just one. That cell contains a button which (when pressed) adds 1 to the 'rows' integer. The problem starts, when it starts reusing cells (I am guessing) and content start disappearing. When I scroll back up, the UILabels I am putting in the cells are gone. Is there some bug, code error, mistake, dumb-ass-move I am missing here? Hope anyone can help.

  • Extract wrong data from a frame in C?

    - by ipkiss
    I am writing a program that reads the data from the serial port on Linux. The data are sent by another device with the following frame format: |start | Command | Data | CRC | End | |0x02 | 0x41 | (0-127 octets) | | 0x03| ---------------------------------------------------- The Data field contains 127 octets as shown and octet 1,2 contains one type of data; octet 3,4 contains another data. I need to get these data. Because in C, one byte can only holds one character and in the start field of the frame, it is 0x02 which means STX which is 3 characters. So, in order to test my program, On the sender side, I construct an array as the frame formatted above like: char frame[254]; frame[0] = 0x02; // starting field frame[1] = 0x41; // command field which is character 'A' ..so on.. And, then On the receiver side, I take out the fields like: char result[254]; // read data read(result); printf("command = %c", result[1]); // get the command field of the frame // get other field's values the command field value (result[1]) is not character 'A'. I think, this because the first field value of the frame is 0x02 (STX) occupying 3 first places in the array frame and leading to the wrong results on the receiver side. How can I correct the issue or am I doing something wrong at the sender side? Thanks all. related questions: http://stackoverflow.com/questions/2500567/parse-and-read-data-frame-in-c http://stackoverflow.com/questions/2531779/clear-data-at-serial-port-in-linux-in-c

  • Grails bean-fields plugin

    - by Don
    Hi, I'm having problems using the Grails bean-fields plugin with a class this is annotated Validateable, but is not a domain/command class. The root cause of the problem appears to be in this method of BeanTagLib.groovy private def getBeanConstraints(bean) { if (bean?.metaClass?.hasProperty(bean, 'constraints')) { def cons = bean.constraints if (cons != null) { if (log.debugEnabled) { log.debug "Bean is of type ${bean.class} - the constraints property was a [${cons.class}]" } // Safety check for the case where bean is no a proper domain/command object // This avoids confusing errors where constraints comes back as a Closure if (!(cons instanceof Map)) { if (log.warnEnabled) { log.warn "Bean of type ${bean.class} is not a domain class, command object or other validateable object - the constraints property was a [${cons.class}]" } } } else { if (log.warnEnabled) { log.warn "Bean of type ${bean.class} has no constraints" } } return cons } else return null } I tested out this method above in the grails console and when I pass an instance of MyBean into this method, it logs: Bean of type ${bean.class} is not a domain class, command object or other validateable object - the constraints property was a [${cons.class}] Because the constraints are returned as an instance of Closure instead of a Map. If I could figue out how to get a Map reference to the constraints of a @Validateable class (that is not a domain/command class), I guess I could resolve the problem. Thanks, Don

  • Metamorphs Messing Up CSS in Ember.js Views

    - by Austin Fatheree
    I'm using Ember.js / handlebars to loop through a collection and spit out some items that I'd like bootstrap to handle nice and responsive like. Here is the issue: The bootstrap-responsive css has some declrations in it like: .row-fluid > [class*="span"]:first-child { margin-left: 0; } and .row-fluid:before, .row-fluid:after { display: table; content: ""; } These rules seem to target the first children. When I loop through my collection in handlebars I end up with a bunch of metamorph code around my items: <div class="row-fluid"> {{#each restaurantList}} {{view GS.vHomePageRestList content=this class="span6"}} {{/each}} </div> Here is what is produced: <div class="row-fluid"> <script id="metamorph-9-start" type="text/x-placeholder"></script> <script id="metamorph-104-start" type="text/x-placeholder"></script> <div id="ember2527" class="ember-view span6"> My View </div> <script id="metamorph-104-end" type="text/x-placeholder"></script> <script id="metamorph-105-start" type="text/x-placeholder"></script> <div id="ember2574" class="ember-view span6"> My View 2 </div> <script id="metamorph-105-end" type="text/x-placeholder"></script> <script id="metamorph-9-end" type="text/x-placeholder"></script> </div> So my question is this: 1. How can I tell css to ignore script tags? or 2. How can I edit the css bindings so that they skip over script tags when selecting the first or first child? or 3. How can I structure this so that Ember uses fewer/no metamorph tags? Here is a fiddle: http://jsfiddle.net/skilesare/SgwsJ/

  • ASP MVC: Submitting a form with nested user controls

    - by Nigel
    I'm fairly new to ASP MVC so go easy :). I have a form that contains a number of user controls (partial views, as in System.Web.Mvc.ViewUserControl), each with their own view models, and some of those user controls have nested user controls within them. I intended to reuse these user controls so I built up the form using a hierarchy in this way and pass the form a parent view model that contains all the user controls' view models within it. For example: Parent Page (with form and ParentViewModel) -->ChildControl1 (uses ViewModel1 which is passed from ParentViewModel.ViewModel1 property) -->ChildControl2 (uses ViewModel2 which is passed from ParentViewModel.ViewModel2 property) -->ChildControl3 (uses ViewModel3 which is passed from ViewModel2.ViewModel3 property) I hope this makes sense... My question is how do I retrieve the view data when the form is submitted? It seems the view data cannot bind to the ParentViewModel: public string Save(ParentViewModel viewData)... as viewData.ViewModel1 and viewData.ViewModel2 are always null. Is there a way I can perform a custom binding? Ultimately I need the form to be able to cope with a dynamic number of user controls and perform an asynchronous submission without postback. I'll cross those bridges when I come to them but I mention it now so any answer won't preclude this functionality. Many thanks.
