  • SO what RDF database do i use for product attribute situation initially i thought about using EAV?

    - by keisimone
    Hi, i have a similar issue as espoused in http://stackoverflow.com/questions/695752/product-table-many-kinds-of-product-each-product-has-many-parameters i am convinced to use RDF now. only because of one of the comments made by Bill Karwin in the answer to the above issue but i already have a database in mysql and the code is in php. 1) So what RDF database should I use? 2) do i combine the approach? meaning i have a class table inheritance in the mysql database and just the weird product attributes in the RDF? I dont think i should move everything to a RDF database since it is only just products and the wide array of possible attributes and value that is giving me the problem. 3) what php resources, articles should i look at that will help me better in the creation of this? 4) more articles or resources that helps me to better understand RDF in the context of the above challenge of building something that will better hold all sorts of products' attributes and values will be greatly appreciated. i tend to work better when i have a conceptual understanding of what is going on. Do bear in mind i am a complete novice to this and my knowledge of programming and database is average at best.

  • ASP.NET MVC Paging for a search form

    - by James Alexander
    I've read several different posts on paging w/ in MVC but none describe a scenario where I have something like a search form and then want to display the results of the search criteria (with paging) beneath the form once the user clicks submit. My problem is that, the paging solution I'm using will create <a href="..."> links that will pass the desired page like so: http://mysite.com/search/2/ and while that's all fine and dandy, I don't have the results of the query being sent to the db in memory or anything so I need to query the DB again. If the results are handled by the POST controller action for /Search and the first page of the data is rendered as such, how do I get the same results (based on the form criteria specified by the user) when the user clicks to move to page 2? Some javascript voodoo? Leverage Session State? Make my GET controller action have the same variables expected by the search criteria (but optional), when the GET action is called, instantiate a FormCollection instance, populate it and pass it to the POST action method (there-by satisfying DRY)? Can someone point me in the right direction for this scenario or provide examples that have been implemented in the past? Thanks!

  • Remove "Flash" between pages while using Internet Explorer modal boxes

    - by AaronS
    I have an internal web application, that is IE specific, and uses a lot of IE specific modal boxes: (window.showModalDialog). I recently received a request to remove the "flash" when navigating between pages of the site. To accomplish this, I just added a meta transition tag to my master page: <meta http-equiv="Page-Enter" content="blendTrans(duration=0.0)" /> This works perfectly except for the modal boxes. When you launch a modal box, and then move it around, the web page behind it keeps a trail of the modal box instead of re-drawing the web page content. This prevents the user from moving the modal box to read anything that was behind it. Is there a way to prevent the "flash" between pages in an IE specific site and have the site still work with modal boxes? Please note, this is a large and complex site, so re-architecting it to not use modal boxes isn't an option. This is an asp.net, c# web application, and all of my users are using IE 7 and IE 8 if it makes any difference. -Edit- To duplicate this, put the following into an html page, and open it in Internet Explorer: <html> <head> <title>Test</title> <meta content="blendTrans(duration=0.0)" http-equiv="Page-Exit"> </head> <body> <script language="javascript"> window.showModalDialog('modal.htm', window); </script> </body> </html>

  • How do you rotate a sprite around its center by caclulating a new x and y position?

    - by Sam152
    I'm using Dark GDK and C++ to create a simple 2d game. I'm rotating an object but it rotates from the top left corner of the sprite. I have the following variables available: PlayerX PlayerY PlayerWidth PlayerHeight RotateAngle (360 x 0) Is there an algorithm that will modify the pivot point of the sprite, preferable to the center? Here is a small code sample: void Player::Move( void ) { if ( checkLeft() ) { PlayerX -= PlayerSpeed; if ( PlayerX < 0 ) PlayerX = 0; } if ( checkRight() ) { PlayerX += PlayerSpeed ; if ( PlayerX > 800 - PlayerWidth ) PlayerX = 800 - PlayerWidth; } if ( checkUp()) { PlayerY -= PlayerSpeed; if ( PlayerY < 0 ) PlayerY = 0; } if ( checkDown()) { PlayerY += PlayerSpeed; if ( PlayerY > 600 - PlayerHeight) PlayerY = 600 - PlayerHeight; } RotateAngle += 5; if(RotateAngle > 360) RotateAngle -=360; dbRotateSprite(Handle,RotateAngle); dbSprite ( 1 , PlayerX , PlayerY , Handle ); } Edit I'm considering opening up some reputation for this question, I have yet to be provided with an answer that works for me. If someone can provide an actual code sample that does the job, I'd be very happy. The problem with Blindy's answer is that no matter how much I simply translate it back or forth, the spirte still rotates around the top left hand corner and moving it somewhere rotating around the top left corner, then moving it back to the same position accomplishes nothing. Here is what I believe to be going on: Just so there is no confusion I have created a an image of what is going on. The left shows what is actually happening and the right shows what I need to happen.

  • Mono doesn't write settings defaults

    - by Petar Minchev
    Hi guys! Here is my problem. If I use only one Windows Forms project and call only - Settings.Default.Save() when running it, Mono creates a user.config file with the default value for each setting. It is fine, so far so good. But now I add a class library project, which is referenced from the Windows Forms project and I move the settings from the Windows Forms project to the Class Library one. Now I do the same - Settings.Default.Save() and to my great surprise, Mono creates a user.config file with EMPTY values(NOT the default ones) for each setting?! What's the difference between having the settings in the Windows Forms Project or in the class library one? And by the way it is not a operating system issue. It is a Mono issue, because it doesn't work both under Windows and Linux. If I don't use Mono everything is fine, but I have to port my application to Linux, so I have to use Mono. I am really frustrated, it is blocking a project:( Thanks in advance for any suggestion you have. Regards, Petar

  • DataGridView: how to make scrollbar in sync with current cell selection?

    - by David.Chu.ca
    I have a windows application with DataGridView as data presentation. Every 2 minutes, the grid will be refreshed with new data. In order to keep the scroll bar in sync with the new data added, I have to reset its ScrollBars: dbv.Rows.Clear(); // clear rows SCrollBars sc = dbv.ScrollBars; dbv.ScrollBars = ScrollBars.None; // continue to populate rows such as dbv.Rows.Add(obj); dbv.ScrollBars = sc; // restore the scroll bar setting back With above codes, the scroll bar reappears fine after data refresh. The problem is that the application requires to set certain cell as selected after the refresh: dbv.CurrentCell = dbv[0, selectedRowIndex]; With above code, the cell is selected; however, the scroll bar's position does not reflect the position of the selected cell's row position. When I try to move the scroll bar after the refresh, the grid will jump to the first row. It seems that the scroll bar position is set back to 0 after the reset. The code to set grid's CurrentCell does not cause the scroll bar to reposition to the correct place. There is no property or method to get or set scroll bar's value in DataGriadView, as far as I know. I also tried to set the selected row to the top: dbv.CurrentCell = dbv[0, selectedRowIndex]; dbv.FirstDisplayedScrollingRowIndex = selectedRowIndex; The row will be set to the top, but the scroll bar's position is still out of sync. Not sure if there is any way to make scroll bar's position in sync with the selected row which is set in code?

  • inserting selected page from one word document in another word document with c#

    - by daemonkid
    I have a requirement to move selected pages from word DocumentA into another word DocumentB. So in the end DocumentB should have its own contents plus selected pages from DocumentA inserted at selected pages in DocumentB. The page number in DocumentB I will set thru properties. This is the code I am using to just append contents of DocumentA to DocumentB. object missing = System.Reflection.Missing.Value; Word._Application wordApp = new Word.Application(); Word._Document aDoc = new Word.Document(); try { wordApp.Visible = false; object readOnly = false; object isVisible = false; aDoc = wordApp.Documents.Open(ref fPath1, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible, ref missing, ref missing, ref missing, ref missing); Word.Selection selection = wordApp.Selection; selection.InsertFile(fPath2, ref missing, ref missing, ref missing, ref missing); aDoc.Save(); wordApp.Quit(ref missing, ref missing, ref missing); } catch(Exception ex) { throw new Exception(ex.Message); } finally { wordApp = null; aDoc = null; } However, I keep getting this exception 'object reference not set to instance of object' at the line 'selection.InsertFile...' What is going wrong here? And how do I insert contents of page 2 from DocumentA into page 3 of DocumentB? Thanks for your time.

  • A moral dilemma - What job to go for?

    - by StefanE
    Here is the story: I have accepted an offer from a gaming company to work as an senior test engineer / developer. I have not yet received an signed copy of the contract. I will get a bit less salary then I asked for and it is as well less than I have today. The company have booked flight tickets for my move over there. Now comes the problem. I did an telephone interview with a company last week and they have asked me for an in person interview and are willing to pay for flights for the meeting. This company is my first choice(and have been for a few years) and would also benefit my career and I believe I will enjoy working there more. What should I do here.. I do feel uncomfortable giving a last minute rejection when I have over the phone accepted the offer, but on the other hand they have yet produced a signed contract and as well paying me a bit less than I think I'm worth. The business is small in many ways and I don't want to end up with a bad reputation. Would be great to hear your opinions!

  • Can iPad/iPhone Touch Points be Wrong Due to Calibration?

    - by Kristopher Johnson
    I have an iPad application that uses the whole screen (that is, UIStatusBarHidden is set true in the Info.plist file). The main window's frame is set to (0, 0, 768, 1024), as is the main view in that frame. The main view has multitouch enabled. The view has code to handle touches: - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { for (UITouch *touch in touches) { CGPoint location = [touch locationInView:nil]; NSLog(@"touchesMoved at location %@", NSStringFromCGPoint(location)); } } When I run the app in the simulator, it works pretty much as expected. As I move the mouse from one edge of the screen to the other, reported X values go from 0 to 767. Reported Y values go from 20 to 1023, but it is a known issue that the simulator doesn't report touches in the top 20 pixels of the screen, even when there is no status bar. Here's what's weird: When I run the app on an actual iPad, the X values go from 0 to 767 as expected, but reported Y values go from -6 to 1017. The fact that it seems to work properly on the simulator leads me to suspect that real devices' touchscreens are not perfectly calibrated, and mine is simply reporting values six pixels too low. Can anyone verify that this is the case? Otherwise, is there anything else that could account for the Y values being six pixels off from what I expect? (In a few days, I should have a second iPad, so I can test this with another device and compare the results.)

  • Could you please provide me with comments on a Java game of mine?

    - by Peter Perhác
    Hello there. I have marked this question as community wiki, so no rep points are thrown around. I made this game, Forest Defender, a proof-of-feasibility little project, which I would like to share with you and collect your constructive comments, first impressions, etc. It is a the first playable (and enjoyable) game I have released to the public, so I am, naturally, very eager to get some recognition by you, as my peers. I read in a StackOverflow blog, that One of the major reasons we created Stack Overflow to give every programmer a chance to be recognized by their peers. Recognized for their knowledge, their passion, [...] It comes in the form of a Java applet, I used an animation framework called PulpCore and I must say that it's been extremely enjoyable to work with it. I do recommend to people interested in Java game development. Since the product is free, fun, entirely commercial-free and I am willing to share the code to it (on request), I thought it would be OK to post this as a topic here. Moderators, please feel free to move this to another place if you deem the other place more appropriate.

  • ListView Final Column Autosize creates scrollbar

    - by Courtney de Lautour
    Hi There, I am implementing a custom control which derives from ListView. I would like for the final column to fill the remaining space (Quite a common task), I have gone about this via overriding the OnResize method: protected override void OnResize(EventArgs e) { base.OnResize(e); if (Columns.Count == 0) return; Columns[Columns.Count - 1].Width = -2; // -2 = Fill remaining space } or via another method: protected override void OnResize(EventArgs e) { base.OnResize(e); if (!_autoFillLastColumn) return; if (Columns.Count == 0) return; int TotalWidth = 0; int i = 0; for (; i < Columns.Count - 1; i++) { TotalWidth += Columns[i].Width; } Columns[i].Width = this.DisplayRectangle.Width - TotalWidth; } Edit: This works fine until I dock the ListView into a parent container and resize via that control. Every second time the control size shrinks (IE, drag the the border one pixel), I get a scroll bar on the bottom which can't move at all (not even one pixel). The result of which is when I drag the size of the parent I am left with a flickering scroll bar in the ListView, and a 50% chance it will be there when the dragging stops.

  • General Address Parser for Freeform Text

    - by Daemonic
    We have a program that displays map data (think Google Maps, but with much more interactivity and custom layers for our clients). We allow navigation via a set of combo boxes that prefill certain fields with a bunch of data (ie: Country: Canada, the Province field is filled in. Select Ontario, and a list of Counties/Regions is filled in. Select a county/region, and a city is filled in, etc...). While this guarantees accurate addresses, it's a pain for the users if they don't know where a street address or a city are located (ie, which county/region is kitchener in?). So we are looking at trying to do an address parser with a freeform text field. The user could enter something like this (similar to Google Maps, Bing Maps, etc...): 22 Main St, Kitchener, On And we could compartmentalize it into sections and do lookups on the data and get to the point they are looking for (or suggest alternatives). The problem with this is that how do we properly compartmentalize information? How do we break up the sections and find possible matches? I'm guessing we wouldn't be guaranteed that the user would enter data in a format we always expected (obviously). A follow up to this would be how to present the data if we don't find an exact match (or find multiple exact matches... two cities with the same street name in different counties, for example). We have a ton of data available in the mapping data (mapinfo tab format mostly). So we can do quick scans of street names, cities, states, etc. But I'm not sure about the best way to go about approaching this problem. Sure, using Google Maps would be nice, bue most of our clients are in closed in networks where outside access is not usually allowed and most aren't willing to rely on google maps (since it doesn't contain as much information as they need, such as custom map layers). They could, obviously, go to google and get the proper location then move to our software, but this would time consuming and speed of the process can be quite important.

  • Optional Member Objects

    - by David Relihan
    Okay, so you have a load of methods sprinkled around your systems main class. So you do the right thing and refactor by creating a new class and perform move method(s) into a new class. The new class has a single responsibility and all is right with the world again: class Feature { public: Feature(){}; void doSomething(); void doSomething1(); void doSomething2(); }; So now your original class has a member variable of type object: Feature _feature; Which you will call in the main class. Now if you do this many times, you will have many member-objects in your main class. Now these features may or not be required based on configuration so in a way it's costly having all these objects that may or not be needed. Can anyone suggest a way of improving this? At the moment I plan to test in the newly created class if the feature is enabled - so the when a call is made to method I will return if it is not enabled. I could have a pointer to the object and then only call new if feature is enabled - but this means I will have to test before I call a method on it which would be potentially dangerous and not very readable. Would having an auto_ptr to the object improve things: auto_ptr<Feature> feature; Or am I still paying the cost of object invokation even though the object may\or may not be required. BTW - I don't think this is premeature optimisation - I just want to consider the possibilites.

  • How can I modify my code to line through the bezier control points?

    - by WillyCornbread
    HI all - I am using anchor points and control points to create a shape using curveTo. It's all working fine, but I cannot figure out how to get my lines to go through the center of the control points (blue dots) when the line is not straight. Here is my code for drawing the shape: // clear old line and draw new / begin fill var g:Graphics = graphics; g.clear(); g.lineStyle(2, 0, 1); g.beginFill(0x0099FF,.1); //move to starting anchor point var startX:Number = anchorPoints[0].x; var startY:Number = anchorPoints[0].y; g.moveTo(startX, startY); // Connect the dots var numAnchors:Number = anchorPoints.length; for (var i:Number=1; i<numAnchors; i++) { // curve to next anchor through control g.curveTo(controlPoints[i].x,controlPoints[i].y, anchorPoints[i].x, anchorPoints[i].y); } // Close the loop g.curveTo(controlPoints[0].x,controlPoints[0].y,startX,startY); And the shape I'm drawing for reference: How can I modify my code so that the lines go directly through the blue control points? Thanks in advance! b

  • My 3D object (opengl es) is disappearing behind the iPhone camera view

    - by KLC
    I have an augmented reality iPhone app that I am converting from Core Animation to OpenGL ES 1.1. I have added code that has been modified from the Apple OpenGL template. My problem is that my 3D object , when translating along the negative Z-axis (away from the user), appears to disappear into the camera view, until its completely gone. I have experimented with several solutions, but to no avail. What I have determined: Using the 3D icosahedron from Jeff Lamarche's blog here, the object starts it at 0,0,0 and then translates with decreasing z coordinates. By the time the z value reaches -2.0f, the object is gone. It appears as if it is disappearing behind the camera view. This is how I set my frustrum & viewport (unchanged from Apple's code) glMatrixMode(GL_PROJECTION); size = zNear * tanf(DEGREES_TO_RADIANS(fieldOfView) / 2.0); //Grab the size of the screen CGRect rect = self.bounds; glFrustumf(-size, size, -size / (rect.size.width / rect.size.height), size / (rect.size.width / rect.size.height), zNear, zFar); glViewport(0, 0, rect.size.width, rect.size.height); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); What I have tried: The camera view is the main view and several other views are added to it as subviews, including the openGLView. I have commented those views out for test purposes. I have applied CATransforms to move the openGLView in the z direction -500 and +500, and done the same to the camera view. I have also changed the zFar in the above code to 1.0f, and it still disappears at z position of -2.0, which doesn't make sense (shouldn't it disappear at z=1.0?) My experimentation has got me more confused than when I started ( which usually means I am missing a key piece, but I can't figure out what). Thanks for your help.

  • Moving .NET assemblies away from the application base directory?

    - by RasmusKL
    I have a WinForms application with a bunch of third party references. This makes the output folder quite messy. I'd like to place the compiled / referenced dlls into a common subdirectory in the output folder, bin / lib - whatever - and just have the executables (+ needed configs etc) reside in the output folder. After some searching I ran into assembly probing (http://msdn.microsoft.com/en-us/library/4191fzwb.aspx) - and verified that if I set this up and manually move the assemblies my application will still work if they are stored in the designated subdirectory like so: <configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="bin" /> </assemblyBinding> </runtime> </configuration> However, this doesn't solve the build part - is there any way to specify where referenced assemblies and compiled library assemblies go? Only solutions I can think of off the top of my head is either post-build actions or dropping the idea and using ILMerge or something. There has got to be a better way of defining the structure :-)

  • MSBuild file for deployment process

    - by Lee Englestone
    I could do with some pointers, code examples or references that may help me do the following in an msbuild file to help speed up the deployment process.. This scenario involves getting a developers 'local' version onto a 'development' server.. Increment a developers local Web Applications Assembly version number Publish a developers local Web Application files somewhere .rar the publsihed files or folder into the format v[IncrementedAssemblyNumber].rar Copy the .rar to somewhere Backup (.rar) the existing live website folder (located elsewhere) in the format Pre_v[IncrementedAssemblyNumber].rar Move the backed up .rar to a /Backup folder. Overwrite the development web files with the published local web files Should be simple for all those MSBUILD Gurus out there. Like I said, answers or 'Good and applicable' links would be much appreciated. Also i'm thinking of getting one of the MSbuild books. From what I can tell there are 2, possibly 3 contenders. I am not using TFS. Can anyone recommend a book for beginning MSBUILD? Ideally from people that have read more than one book on the subject. Cheers, -- Lee

  • C# Windows Service doesn't seem to like privatePath

    - by SauerC
    I wrote a C# Windows Service to handle task scheduling for our application. I'm trying to move the "business rules" assemblies into a bin subdirectory of the scheduling application to make it easier for us to do updates (stop service, delete all files in bin folder, replace with new ones, start service). I added <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="bin;"/> </assemblyBinding> </runtime> to the service's app config and it works fine if the service is run as a console application. Problem is when the service is run as a windows service it doesn't work. It appears that when windows runs the service the app config file gets read properly but then the service is executed as if it was in c:\windows\system32 and not the actually EXE location and that gums up the works. We've got a lot of assemblies so I really don't want to use the GAC or <codeBase>. Is it possible to have the EXE change it's base directory back to where it should be when it's run as a service?

  • Javascript Mouseover bubbling from children

    - by Nicky De Maeyer
    Ive got the following html setup: <div id="div1"> <div id="content1">blaat</div> <div id="content1">blaat2</div> </div> it is styled so you can NOT hover div1 without hovering one of the other 2 divs. Now i've got a mouseout on div1. The problem is that my div1.mouseout gets triggered when i move from content1 to content2, because their mouseouts are bubbling. and the event's target, currentTarget or relatedTarget properties are never div1, since it is never hovered directly... I've been searching mad for this, but I can only find articles and solutions for problems who are the reverse of what I need. It seems trivial but I can't get it to work... The mouseout of div1 should ONLY get triggered when the mouse leaves div1. One of the possibilities would be to set some data on mouse enter and mouseleave, but I'm convinced this should work out of the box, since it is just a mouseout... EDIT: bar.mouseleave(function(e) { if ($(e.currentTarget).attr('id') == bar.attr('id')) { bar.css('top', '-'+contentOuterHeight+'px'); $('#floatable-bar #floatable-bar-tabs span').removeClass('active'); } }); changed the mouseout to mouseleave and the code worked...

  • Can I specify the files to commit in subversion in a file rather than on the command line?

    - by René Nyffenegger
    I have renamed (with svn move) a lot of files in a subversion project. Now, I am trying to commit these on Window's cmd.exe. It seems that I hit a limit (probably by cmd.exe) in that the number of files is too long for the command line to swallow. Now, I thought and hoped that I could list the files to commit in a seperate file that I could specify with the commit command (something like svn ci --files-to-commit=renamed-files.txt -m "Renamed a lot of files" Yet, either such an option does not exist or I am unable to find this. Unfortunately, I cannot do a svn ci . as I have done other changes in the project as well. Neither can I do a svn ci *pattern-of-renamed-files* since this would only check in the added files, not the deleted ones. Before I start checking in the files with smaller chunks of files to check in (and thus increase the revision number uneccesserily without giving a hint as to the 'atomicity' of the operation) I thought I ask if this is indeed impossible to do.

  • Presenting an image cropping interface

    - by wkw
    I'm trying to engineer a UI for cropping images in iphone OS and suspect I'm going about things the hard way. My goal is pretty much what the Tapbots duo have done with Pastebot. In that app, they dim the source image but provide a movable and resizable cropping view and the image you're cropping is in a zoomable scrollview; when you resize or move the underlying image, the cropping view adjusts appropriately. I mocked up a composite image which will give a sense of the design I'm after, along with how I presently have my view hierarchy setup, viewable here The approach I've started with is the following: UIImageView with the image to crop is in a scrollview, a plain UIView with black fill and suitable transparency/alpha setting is added in front of the imageview. I then use a custom UIView which is a sibling to the scrollview at a higher level, which implements the drawRect: method and for the most part calls CGImageCreateWithImageInRect to get the portion of the image's bitmap that matches the position of the cropping view and draws that to the CGContext. in the viewcontroller I'm using the UIScrollViewDelegate methods to track scrolling and passing those changes to the custom cropping UIView so it stays in sync with the scroll contentOffset. That much is finally working. But trying to keep in sync as the scrollview zoomScale changes is when I figured I should ask for help. Looking for suggestions or guidance. My initial approach just seems like more work than is required. Could this be done with a masking layer in the ImageView? And if so, how would I setup the tracking for moving and resizing the cropping rect? My experience working with layers is non-nil, but very limited thus far.

  • Wondering where to begin

    - by Cat
    Hello all. After being interested for years and years (and years), I have finally decided to start learning how to create software and web applications. Base on recommendations, I have started with learning the basics of web design first (which I am almost done with) and then will move on to the meat of my process: learning the languages. Problem is, I don't know where to start :/ PHP, Ruby, Perl...and where would SQL, JavaScript and .NET fit into the mix? I am assuming they build on each other/play off of each other somewhat so following some sort of 'order' will make the process more logical and digestible. You're probably thinking, "Just go to school for computer engineering, duh!" But I already have a degree and don't plan on going back to school. I believe I have an adequate aptitude for this sort of thing, and although it will be challenging, with the support of the community I know I can do it on my own. Thank in advance everyone and I am very sorry for the length. I look forward to hearing what all you have to say. Warm Regards, Cat

    Okay, so I'm trying to get into this whole HTML 5 thing, and this tutorial (http://www.webreference.com/authoring/languages/html/HTML5/) says that these tags should move the content around without any kind of CSS at all, but all I'm getting is a line of text that looks like this: Header tag Nav tag Artical Section tags Aside tag footer tag Here is the code: <!DOCTYPE html> <html lang="en"> <head> <title>HTML5 test1</title> <meta charset="utf-8" /> </head> <body> <header> Header tag </header> <nav> Nav tag </nav> <article> <section> Artical Section tags </section> </article> <aside> Aside tag </aside> <footer> footer tag </footer> </body> </html>

  • Google App Engine Needs Index Error

    - by Andrew Johnson
    I am currently getting a needs index error on my app engine app: http://www.gaiagps.com/wiki/home. I believe this index should have been created automatically by my index.yaml file (see below). Googling a bit, I think I just need to wait for my index to be built. Is this correct, or do I need to do something manually? Is there some sort of index-building queue? My tables are very, very small right now. EDIT: I added the line "indexes:" to my app.yaml, and now app engine reports the index is building, so I think this is fixed. It's weird that this file was wrong considering I've never touched it. indexes: # AUTOGENERATED # This index.yaml is automatically updated whenever the dev_appserver # detects that a new type of query is run. If you want to manage the # index.yaml file manually, remove the above marker line (the line # saying "# AUTOGENERATED"). If you want to manage some indexes # manually, move them above the marker line. The index.yaml file is # automatically uploaded to the admin console when you next deploy # your application using appcfg.py. - kind: Revision properties: - name: name - name: created The app works on my dev server, but not in production. However, on my dev console, I have noticed this error (EDIT: THIS ERROR IS GONE NOW THAT I ADDED indexes: to the app.yaml file above): ERROR 2009-10-18 04:46:51,908 dev_appserver_index.py:176] Error parsing /gaiagps.com/index.yaml: 'NoneType' object is not callable in "<string>", line 13, column 3: - kind: Revision ^
