• User Friendly Video Review with Locking

  - by James Cori

  We have a jquery/php/mysql system that allows a user to log in and review videos built by a system for online viewing. When a user begins reviewing a video, the video is marked as such. But now we've cornered ourselves into the classic browser-based application problem of the user navigating away or closing the browser without completing review. That video would then enter a state of limbo of constantly being reviewed, but never completed, and never re-entering the queue. Options we have are: Build a service (which we already have others) to find review sessions that are outside a duration boundary and reset them back into the queue. Reset review sessions outside a duration boundary when that user logs in. Essentially, if a user locks out a video for review, it'll be unlocked the next time they log in. A suggestion made to me was to use the php/apache session length and on expiration, reset any pending review jobs. I don't even know where to look to implement this as this is one project on a shared server, so it shouldn't be an apache config, but the reset mechanism would need to know the database credentials to be able to reset it... The worst solution everyone hates is preventing the user from navigating away with javascript, asking "Are you sure?!" This system is used by a few hired reviewers, so I'm not exactly dealing with the public here, but I can't prevent users from sharing logins for speedier review, which would knock out the 2nd option above because it would unlock a video being reviewed by someone else using the same login.

• Building a CMS in PHP: Development tools

  - by TRiG

  I'm planning to build a CMS in PHP and MySQL, mainly for my own amusement and education. (Though who knows, I may come up with something useful and cool. Anything's possible.) I'll be asking questions about code architecture etc. later. For now, I'm more interested in development tools. So far, all my playing with code has been done on a web server, and I've edited over FTP. I was thinking it might be quicker to use a localhost. Also, that way, I could use version control (which I've never done before). So, A. How do I set up a localhost server with many subdomains on an Ubuntu 9.10 computer. Is XAMPP for Linux the way to go, or should I use a standard Apache distro? (Or another webserver altogether?) For that matter, is it possible to set up more than one webserver on the same computer, and to use them for different localhost subdomains? B. How do I set up a version control thingy covering all the code (which will be on several subdomains of localhost, and in a few shared folders)? I've read Joel Spolsky's HgInt tutorial, and it makes Mercurial look good. And simple, especially if you're working on your own. C. Should I continue to use gEdit to write HTML/CSS/JS/PHP, or is there a better free editor out there for these languages?

• How to maintain base files for development environment central while allowing people to change their

  - by Ittai

  Hi, what I'd like to do is have files in a central location so that when I add people to my development team they can see the base version of these files but meanwhile have the ability for the rest of the team to work with their own local version. I know I can just put the files in source-control (we use Tortoiese-SVN) and have my team change the local versions but I'd rather not as the exclamation mark signaling the file has been changed and needs to be committed, quite frankly, irritates me greatly. I'll give two examples of what I mean: We use quite a few build.xml files which relate to a single properties files which contains many definitions. Some of them can be different between team-members (mainly temporary working directories) and I'd like a new team-member to have the ability to get the properties file with the base config but change it if they wish. Have the eclipse settings file in the SVN so that when a new team-member joins they can just retrieve the files from the server and have a base system running. If they wish they will be able to change some of these settings. Thanks, Ittai

• What happened to the .NET version definition with v4.0?

  - by Tom Tresansky

  I'm building a C# class library, and using the beta 2 of Visual Web Developer/Visual C# 2010. I'm trying to save information about what version of .NET the library was built under. In the past, I was able to use this: // What version of .net was it built under? #if NET_1_0 public const string NETFrameworkVersion = ".NET 1.0"; #elif NET_1_1 public const string NETFrameworkVersion = ".NET 1.1"; #elif NET_2_0 public const string NETFrameworkVersion = ".NET 2.0"; #elif NET_3_5 public const string NETFrameworkVersion = ".NET 3.5"; #else public const string NETFrameworkVersion = ".NET version unknown"; #endif So I figured I could just add: #elif NET_4_0 public const string NETFrameworkVersion = ".NET 4.0"; Now, in Project-Properties, my target Framework is ".NET Framework 4". If I check: Assembly.GetExecutingAssembly().ImageRuntimeVersion I can see my runtime version is v4.0.21006 (so I know I have .NET 4.0 installed on my CPU). I naturally expect to see that my NETFrameworkVersion variable holds ".NET 4.0". It does not. It holds ".NET version unknown". So my question is, why is NET_4_0 not defined? Did the naming convention change? Is there some simple other way to determine .NET framework build version in versions 3.5?

• Error loading shared libraries

  - by user459811

  Hi, I'm running eclipse on Ubuntu using a g++ compiler and I'm trying to run a sample program that utilizes xerces. The build produced no errors however, when i attempted to run the program, I would receive this error: "error while loading shared libraries: libxerces-c-3.1.so: cannot open shared object file: No such file or directory" libxerces-c-3.1.so is in the directory /opt/lib which I have included as a library in eclipse. The file is there when I checked the folder. When I perform an 'echo $LD_LIBRARY_PATH', /opt/lib is also listed. Any ideas into where the problem lies? Thanks. An 'ldd libxerces-c-3.1.so' command yields the following output: linux-vdso.so.1 => (0x00007fffeafff000) libnsl.so.1 => /lib/libnsl.so.1 (0x00007fa3d2b83000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007fa3d2966000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007fa3d265f000) libm.so.6 => /lib/libm.so.6 (0x00007fa3d23dc000) libc.so.6 => /lib/libc.so.6 (0x00007fa3d2059000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007fa3d1e42000) /lib64/ld-linux-x86-64.so.2 (0x00007fa3d337d000)

• Linking Mapkit with Core Data, Search and user location. Converting annotations from a database in a tableview with search to display in a mapview?

  - by Jon

  Xcode is quite new to me so explanations are appreciated. I am looking to build an application that displays annotations in a mapview (zoomed in on current user location). I want the applications to come from some sort of database rather than manually inputting all the annotations (which is what I'm currently doing) What would be my application type? tab based? window based? i want a tab for a tableview with a list of my annotations and a mapview tab that will show my database of annotations but with the map zoomed in on current location. In a perfect world, it would be great if the user could add favourites from these annotations and keep them in a favourites tableview tab. I'm desperate to work this out and create a fully functional app for a final uni project. i have a working application already but it's nothing like what i am trying to achieve, any help would be much appreciated!!!! Jon (if looked through countless tutorials and as of yet found nothing i can understand to achieve a project like this. Some would call me too ambitious, I just want to make a decent app)

• are projects with high developer turn over rate really a bad thing?

  - by John

  I've inherited a lot of web projects that experienced high developer turn over rates. Sometimes these web projects are a horrible patchwork of band aid solutions. Other times they can be somewhat maintainable mozaics of half-done features each built with a different architectural style. Everytime I inherit these projects, I wish the previous developers could explain to me why things got so bad. What puzzles me is the reaction of the owners (either a manager, a middle man company, or a client). They seem to think, "Well, if you leave, I'll just find another developer." Or they think, "Oh, it costs that much money to refactor the system? I know another developer who can do it at half the price. I'll hire him if I can't afford you." I'm guessing that the high developer turn over rate is related to the owner's mentality of "If you think it's a bad idea to build this, I'll just find another (possibly cheaper) developer to do what I want". For the owners, the approach seems to work because their business is thriving. Unfortunately, it's no fun for the developers that go AWOL 3-4 months after working with poor code, strict timelines, and little feedback. So my question is the following: Are the following symptoms of a project really such a bad thing for business? high developer turn over rate poorly built technology - often a patchwork of different and inappropriately used architectural styles owners without a clear roadmap for their web project, and they request features on a whim I've seen numerous businesses prosper while experiencing the symptoms above. So as a programmer, even though my instincts tell me the above points are terrible, I'm forced to take a step back and ask, "are things really that bad in the grand scheme of things?" If not, I will re-evaluate my approach to these projects.

• How to rename goals in Maven?

  - by mjs

  In the Maven document Introduction to the Build Lifecycle, a goal of display:time is described that outputs the current time. The plugin is as follows: ... <plugin> <groupId>com.mycompany.example</groupId> <artifactId>maven-touch-plugin</artifactId> <version>1.0</version> <executions> <execution> <phase>process-test-resources</phase> <goals> <goal>timestamp</goal> </goals> </execution> </executions> </plugin> ... I have several questions relating to this plugin: How can I change the name of the goal to, for example, foo:bar? (Why does neither display nor time appear anywhere in the XML fragment? How can you tell, from looking at the fragment, what goals it defines?) How can I manually run this goal? (For similar constructs, the equivalent of mvn display:time sometimes works, but this doesn't work consistently.) How can I see if this goal exists? (i.e. list available goals; this question suggests this is impossible.)

• How do I send text to a UITextView?

  - by Lee

  I'm new to iphone development. I'm a VB programmer who is trying to convert a VB application to an ipad app. I need some help with sending text to a UITextView. I want to first have a UIPickerView and then once the user hits a UIButton, a UITextView appears and the text is then generated by my source code code, line by line. The code would constantly be concatenating strings to the text. It would sort of go like this-- 1) User makes selections with UIPickerView. 2) User then hits UIButton. 3) UIPickerView is replaced on the screen with a UITextView. 4) The code does stuff. 5) The code adds the 1st line of text into the UITextView. 6) The code does more stuff. 7) The code then adds the 2nd line of text into the UITextView, retaining the 1st line that was already there. Steps 6 and 7 are repeated until the code is done. Does anyone know of any examples of this that I could look at? I am mostly interested in finding something like a youtube video, a webpage that explains the code or even a good book that covers this particular topic. I am finding that the sample codes that Apple has on this site goes over my head. In fact, I could probably benefit from a good book. But, I am looking for one that I would already know covers this particular topic, since it is so essential to the app that I am trying to build.

• How do I use IPTC/EXIF metadata to categorise photos?

  - by kbro

  Many photo viewing and editing applications allow you to examine and change EXIF and IPTC data in JPEG and other image files. For example, I can see things like shutter speed, aperture and orientation in the picture files that come off my Canon A430. There are many, many name/value pairs in all this metadata. But... What do I do if I want to store some data that doesn't have a build-in field name. Let's say I'm photographing an athletics competition and I want to tag every photo with the competitor's bib number. Can I create a "bib_number" field and assign it a values of "0001", "5478", "8124" etc, and then search for all photos with bib_number="5478"? I've spent a few hours searching and the best I can come up with is to put this custom information in the "keywords" field but this isn't quite what I'm after. With this socution I'd have to craft a query like "keywords contains bib_number_5478" whereas what I want it "bib_number is 5478". So do the EXIF and/or IPTC standards allow addtional user-defined field names? Thanks Kev

• NetBeans parameter fill after code completion

  - by byte

  This is a particularly annoying problem I'm having, and I can't be the only one to have issue with it. In NetBeans, when you type part of a method, then hit CTRL-SPACE, it displays the code-completion popup, whereupon you can hit tab to finish out the word. This is great, and pretty much how all IDE's operate. Example: Thread.sl < CTRL-SPACE Thread.sleep Yay! Problem is that in this context, once you type in a paren, it auto-fills the parameters for the method with their default names, and inserts a closing paren (regardless of whether you have disabled the option to automatically close them on the preferences page for code completion). This behavior is NOT present if you had manually typed out the full name. How is this helpful to anyone? You've got to type over it your actual variable that you will be passing, and NetBeans gives you no option to prevent the closing paren on code-completion. Does anyone have a way to solve this issue, without having to dive into the netbeans source and build it just for this minor of an issue?

• WYSIWYG in Doxygen

  - by Adam Shiemke

  I'm working on a fairly large project written in C. The idea was to build a library of modular blocks that can be reused across several platforms. Each module is assocaited with a word document in .docx format (huge pain to diff-merge). In these docs, an interface section is specified, listing datatypes and publicly accessable functions. These were often inconsistant with the actual implementation in code, and wading through all this documentation was a pain. I've been working to switch to doxygen to simplify document managemnet. I haven't found a good way to embed the previously written documentation into the doxygen output. I've copy-pasted them into sections and used modules to group the sources together, but the document sections look ugly in the comments (the output is pretty) and since doxygen takes a while to parse through our code (about 30 mins), validating formatting is a pain. Is there some way to WYSIWIG large blocks of documentation into doxygen? I feel this would improve the number of people documenting their code, and the quality of that documentation. I considered linking to html, but that splits out the documentation. I also considered putting them inline in html, but this also seems like a pain and would mean everyone needs a WYSIWIG HTML edditor (or some html skillz). Any ideas on how to make things easier and prettier? Thanks loads.

• Why is my UIWebView not scrollable?

  - by Thomas

  In my most frustrating roadblock to date, I've come across a UIWebView that will NOT scroll! I call it via this IBAction: -(IBAction)session2ButtonPressed:(id)sender { Session2ViewController *session2View = [[Session2ViewController alloc]initWithNibName:@"Session2ViewController" bundle:nil]; self.addictionViewController = session2View; [self.view insertSubview:addictionViewController.view atIndex:[self.view.subviews count]]; [session2View release]; } In the viewDidLoad of Session2ViewController.m, I have - (void)viewDidLoad { [super viewDidLoad]; // TRP - Grab data from plist // TRP - Build file path to the plist NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Addiction" ofType:@"plist"]; // TRP - Create NSDictionary with contents of the plist NSDictionary *addictionDict = [NSDictionary dictionaryWithContentsOfFile:filePath]; // TRP - Create an array with contents of the dictionary NSArray *addictionData = [addictionDict objectForKey:@"Addiction1"]; NSLog(@"addictionData (array): %@", addictionData); // TRP - Create a string with the contents of the array NSString *addictionText = [NSString stringWithFormat:@"<DIV style='font-family:%@;font-size:%d;'>%@</DIV>", @"Helvetica", 18, [addictionData objectAtIndex:1]]; addictionInfo.backgroundColor = [UIColor clearColor]; // TRP - Load the string created and stored into addictionText and display in the UIWebView [addictionInfo loadHTMLString:addictionText baseURL:nil]; // TODO: MAKE THIS WEBVIEW SCROLL!!!!!! } In the nib, I connected my web view to the delegate and to the outlet. When I run my main project, the plist with my HTML code shows up, but does not scroll. I copied and pasted this code into a new project, wired the nib the exact same way, and badda-boom badda-bing. . . it works. I even tried to create a new nib from scratch in this project, and the exact same code would not work. Whiskey Tango Foxtrot Any ideas?? Thanks! Thomas

• Using AJAX to get a specific DOM Element (using Javascript, not jQuery)

  - by Matt Frost

  How do you use AJAX (in plain JavaScript, NOT jQuery) to get a page (same domain) and display just a specific DOM Element? (Such as the DOM element marked with the id of "bodyContent"). I'm working with MediaWiki 1.18, so my methods have to be a little less conventional (I know that a version of jQuery can be enabled for MediaWiki, but I don't have access to do that so I need to look at other options). I apologize if the code is messy, but there's a reason I need to build it this way. I'm mostly interested in seeing what can be done with the Javascript. Here's the HTML code: <div class="mediaWiki-AJAX"><a href="http://www.domain.com/whatever"></a></div> Here's the Javascript I have so far: var AJAXs = document.getElementsByClassName('mediaWiki-AJAX'); if (AJAXs.length > 0) { for (var i = AJAXs.length - 1; i >= 0; i--) { var URL = AJAXs[i].getElementsByTagName('a')[0].href; xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { AJAXs[i].innerHTML = xmlhttp.responseText; } } xmlhttp.open('GET',URL,true); xmlhttp.send(); } }

• Advanced All In One .NET Framework

  - by alfredo dobrekk

  Hi, i m starting a new project that would basically take input from user and save them to database among about 30 screens, and i would like to find a framework that will allow the maximum number of these features out of the box : .net c#. windows form. unit testing continuous integration screens with lists, combo boxes, text boxes, add, delete, save, cancel that are easy to update when you add a property to your classes or a field to your database. auto completion on controls to help user find its way use of an orm like nhibernate easy multithreading and display of wait screens for user easy undo redo tabbed child windows search forms ability to grant access to some functionnalities according to user profiles mvp/mvvm or whatever design patterns either some code generation from database to c# classe or generation of database schema from c# classes some kind of database versioning / upgrade to easily update database when i release patches to application once in production automatic control resizing code metrics analysis some code generator i can use against my entities that would generate some rough form i can rearrange after code documentation generator ... Any ideas ? I know its lot but i really would like to use existing code to build upon so i can focus on business rules. Could splitting the requirements on 3 or 4 existing open source framework be possible ? Do u have any suggestion to add to the list before starting ? What open source tools would u use to achieve these ?

• 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

• Alpha blending colors in .NET Compact Framwork 2.0

  - by Adam Haile

  In the Full .NET framework you can use the Color.FromArgb() method to create a new color with alpha blending, like this: Color blended = Color.FromArgb(alpha, color); or Color blended = Color.FromArgb(alpha, red, green , blue); However in the Compact Framework (2.0 specifically), neither of those prototypes are valid, you only get: Color.FromArgb(int red, int green, int blue); and Color.FromArgb(int val); The first one, obviously, doesn't even let you enter an alpha value, but the documentation for the latter shows that "val" is a 32bit ARGB value (as 0xAARRGGBB as opposed to the standard 24bit 0xRRGGBB), so it would make sense that you could just build the ARGB value and pass it to the function. I tried this with the following: private Color FromARGB(byte alpha, byte red, byte green, byte blue) { int val = (alpha << 24) | (red << 16) | (green << 8) | blue; return Color.FromArgb(val); } But no matter what I do, the alpha blending never works, the resulting color always as full opacity, even when setting the alpha value to 0. Has anyone gotten this to work on Compact Framework?

• How to do parrallel processing in Unix Shell script?

  - by Bikram Agarwal

  I have a shell script that transfers a build.xml file to a remote unix machine (devrsp02) and executes the ANT task wldeploy on that machine (devrsp02). Now, this wldeploy task takes around 15 minutes to complete and while this is running, the last line at the unix console is - "task {some digit} initialized". Once this task is complete, we get a "task Completed" msg and the next task in the script is executed only after that. But sometimes, there might be a problem with the weblogic domain and the deployment might be failing internally, with no effect on the status of the wldeploy task. The unix console will still be stuck at "task {some digit} initialized". The error of the deployment will be getting logged in a file called output.a So, what I want now is - Start a time counter before running wldeploy. If the wldeploy runs for more than 15 minutes, the following command should be run - tail -f output.a ## without terminating the wldeploy or cat output.a ## after terminating the wldeploy forcefully Point to be noted here is - I can't run the wldeploy task in background, as in that case the user won't get to know when the task is complete, which is crucial for this script. Could you please suggest anything to achieve this?

• 1k of Program Space, 64 bytes of RAM. Is 1 wire communication possible?

  - by Earlz

  (If your lazy see bottom for TL;DR) Hello, I am planning to build a new (prototype) project dealing with physical computing. Basically, I have wires. These wires all need to have their voltage read at the same time. More than a few hundred microseconds difference between the readings of each wire will completely screw it up. The Arduino takes about 114 microseconds. So the most I could read is 2 or 3 wires before the latency would skew the accuracy of the readings. So my plan is to have an Arduino as the "master" of an array of ATTinys. The arduino is pretty cramped for space, but it's a massive playground compared to the tinys. An ATTiny13A has 1k of flash ROM(program space), 64 bytes of RAM, and 64 bytes of (not-durable and slow) EEPROM. (I'm choosing this for price as well as size) The ATTinys in my system will not do much. Basically, all they will do is wait for a signal from the Master, and then read the voltage of 1 or 2 wires and store it in RAM(or possibly EEPROM if it's that cramped). And then send it to the Master using only 1 wire for data.(no room for more than that!). So far then, all I should have to do is implement trivial voltage reading code (using built in ADC). But this communication bit I'm worried about. Do you think a communication protocol(using just 1 wire!) could even be implemented in such constraints? TL;DR: In less than 1k of program space and 64 bytes of RAM(and 64 bytes of EEPROM) do you think it is possible to implement a 1 wire communication protocol? Would I need to drop to assembly to make it fit? I know that currently my Arduino programs linking to the Wiring library are over 8k, so I'm a bit concerned.

• How to apply CSS theme to only a specific jQuery-UI element?

  - by Thierry-Dimitri Roy

  I have a web site already build with my own CSS theme. I'm using jQuery UI "tabs" widget but no CSS from jQuery-UI. Now, I'm trying to add the "Date Picker" widget in one of my page. It would be great if I could reuse jQuery-UI default theme which is just fine. The problem is that the date picker theme is also applied to my tabs CSS. For example the "ui-widget" css properties is applied to both date picker and tabs elements. I can't seem to find a way to apply the css properties to only the date picker. I can't see a "super selector" that only applies to the date picker DIV. What would be the best way to handle this? [EDIT] The datepicker widget is really the problem. I cannot apply CSS style specific to it. Here is the starting code of the DIV that get pops up: <div style="position: absolute; top: 300.4px; left: 149px; display: block;" id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-helper-hidden-accessible"><div class="ui-datepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> As such, I cannot add a super selector. What would be great would be that the date picker widget supports CSS scope. But it does not. I'm stuck manually editing the jQuery CSS file. The Date Picker is currently being refactored. Hopefully the new code will address this issue.

• How to transform a production to LL(1) for a list separated by a semicolon?

  - by Subb

  Hi, I'm reading this introductory book on parsing (which is pretty good btw) and one of the exercice is to "build a parser for your favorite language." Since I don't want to die today, I thought I could do a parser for something relatively simple, ie a simplified CSS. Note: This book teach you how to right a LL(1) parser using the recursive-descent algorithm. So, as a sub-exercice, I am building the grammar from what I know of CSS. But I'm stuck on a production that I can't transform in LL(1) : //EBNF block = "{", declaration, {";", declaration}, [";"], "}" //BNF <block> =:: "{" <declaration> "}" <declaration> =:: <single-declaration> <opt-end> | <single-declaration> ";" <declaration> <opt-end> =:: "" | ";" This describe a CSS block. Valid block can have the form : { property : value } { property : value; } { property : value; property : value } { property : value; property : value; } ... The problem is with the optional ";" at the end, because it overlap with the starting character of {";", declaration}, so when my parser meet a semicolon in this context, it doesn't know what to do. The book talk about this problem, but in its example, the semicolon is obligatory, so the rule can be modified like this : block = "{", declaration, ";", {declaration, ";"}, "}" So, Is it possible to achieve what I'm trying to do using a LL(1) parser?

• Can I cross compile with gcc for an old version of a Linux distro on my Ubuntu 9.10?

  - by Johan

  Hi, I have some old hardware with an old version of say SuSE linux running on it. Now I have this fancy development machine running Ubuntu 9.10. Some of the tools I use to compile my C app (written in Python 2.6.x) are not available on the old SuSe box. So... is it possible to compile for that old machine on my dev box? I have the following steps in mind, but would like to cross-check before venturing off into this quest: 1. Find out which static/shared libs my app needs and find/build target version of them 2. Also find the corresponding header files 3. Feed the correct flags to gcc to use the target headers and libraries 4. Feed the correct flags to gcc to use the correct architecture (i386/i686), or do I need a cross-compilation toolchain. 5. Compile, upload and enjoy ;-) I regularly use avr-gcc and cc65, both are cross compiling. I know that you set up a coss compiler for developing something like a gumstix, so it should be possible to do the same for old/other Linux distros, not? C

• Select those objects whose related objects IDs are *all* in given string

  - by Jannis

  Hi Django people, I want to build a frontend to a recipe database which enables the user to search for a list of recipes which are cookable with the ingredients the user supplies. I have the following models class Ingredient(models.Model): name = models.CharField(max_length=100, unique=True) slug = models.SlugField(max_length=100, unique=True) importancy = models.PositiveSmallIntegerField(default=4) […] class Amount(models.Model): recipe = models.ForeignKey('Recipe') ingredient = models.ForeignKey(Ingredient) […] class Rezept(models.Model): name = models.CharField(max_length=100) slug = models.SlugField() instructions = models.TextField() ingredients = models.ManyToManyField(Ingredient, through=Amount) […] and a rawquery which does exactly what I want: It gets all the recipes whose required ingredients are all contained in the list of strings that the user supplies. If he supplies more than necessary, it's fine too. query = "SELECT *, COUNT(amount.zutat_id) AS selected_count_ingredients, (SELECT COUNT(*) FROM amount WHERE amount.recipe_id = amount.id) AS count_ingredients FROM amount LEFT OUTER JOIN amount ON (recipe.id = recipe.recipe_id) WHERE amount.ingredient_id IN (%s) GROUP BY amount.id HAVING count_ingredient=selected_count_ingredient" % ",".join([str(ingredient.id) for ingredient in ingredients]) rezepte = Rezept.objects.raw(query) Now, what I'm looking for is a way that does not rely on .raw() as I would like to do it purely with Django's queryset methods. Additionally, it would be awesome if you guys knew a way of including the ingredient's importancy in the lookup so that a recipe is still shown as a result even though one of its ingredients (that has an importancy of 0) is not supplied by the user.
