• Loading tables dynamically with NHibernate

  - by Trevor Goertzen

  I'm working on a project that requires me to load tables based on table names stored in another table. More tables will be added to the DB (and by someone else), so creating NHibernate mapping files for each table isn't an option. Does anyone know if it is possible to load tables dynamically using NHibernate? Edit: I should add that I'm on .NET 2.0, so I can't use Fluent NHibernate. Thanks for the suggestion though guys. I will use that as evidence in convincing my associates to upgrade.

• Lightbox close and loading images not showing

  - by Mark Szymanski

  I am using Lightbox 2 and I have followed the short tutorial on how to insert it in a webpage and it works perfectly but the close and refresh images don't show. They are replaced with the classic Mac OS X '?' box. I have checked the paths of these images in the lightbox.js file and they are correct. Thanks in advance!

• Group variables in a boxplot in R

  - by tao.hong

  I am trying to generate a boxplot whose data come from two scenarios. In the plot, I would like to group boxes by their names (So there will be two boxes per variable). I know ggplot would be a good choice. But I got errors which I could not figure out. Can anyone give me some suggestions? sensitivity_out1 structure(c(0.0522902104339716, 0.0521369824334004, 0.0520240345973737, 0.0519818337359876, 0.051935071418996, 0.0519089404325544, 0.000392698277338341, 0.000326135474295325, 0.000280863338343747, 0.000259631566041935, 0.000246594043996332, 0.000237923540393391, 0.00046732650331544, 0.000474448907808135, 0.000478287273678457, 0.000480194683464109, 0.000480631753078668, 0.000481760272726273, 0.000947965771207979, 0.000944821699830455, 0.000939631071343889, 0.000937186900570605, 0.000936007346568281, 0.000934756220144141, 0.00132442589501872, 0.00132658367774979, 0.00133334696220742, 0.00133622384928092, 0.0013381577476241, 0.00134005741746304, 0.0991622968751298, 0.100791399440082, 0.101946808417405, 0.102524244727408, 0.102920085260477, 0.103232984259916, 0.0305219507186844, 0.0304635269233494, 0.0304161055015213, 0.0303742106794513, 0.0303381888169022, 0.0302996157711171, 1.94268588634518e-05, 2.23991225564447e-05, 2.5756135487907e-05, 2.79997917298194e-05, 3.00753967077715e-05, 3.16270817369878e-05, 0.544701146678523, 0.542887331601984, 0.541632986366816, 0.541005610554556, 0.540617004208336, 0.540315690692195, 0.000453386694666078, 0.000448473414508756, 0.00044692043197248, 0.000444826296854332, 0.000445747996014684, 0.000444764303682453, 0.000127569551159321, 0.000128422491392669, 0.00012933662856487, 0.000129941842982939, 0.000129578971489026, 0.000131113075233758, 0.00684610571790029, 0.00686349387897349, 0.00687468164010565, 0.00687880720347743, 0.00688275579317197, 0.00687822247621936), .Dim = c(6L, 12L)) out2 structure(c(0.0189965816735366, 0.0189995096225103, 0.0190099362589894, 0.0190033523148514, 0.01900896721937, 0.0190099427513381, 0.00192043989797585, 0.00207303208721059, 0.00225931163225165, 0.0024049969048389, 0.00252310364086785, 0.00262940166568126, 0.00195164921633517, 0.00190079923515755, 0.00186139563778548, 0.00184188171395076, 0.00183248544676564, 0.00182492970673969, 1.83038731485927e-05, 1.98252671720347e-05, 2.14794764479231e-05, 2.30713122969332e-05, 2.4484220713564e-05, 2.55958833705284e-05, 0.0428066864455102, 0.0431686808647809, 0.0434411033615353, 0.0435883377765726, 0.0436690169266633, 0.0437340464360965, 0.145288252474567, 0.141488776430307, 0.138204532539654, 0.136281799717717, 0.134864952272761, 0.133738386148036, 0.0711728636959696, 0.072031388688795, 0.0727536853228245, 0.0731581966147734, 0.0734424337399303, 0.0736637270702609, 0.000605277151497094, 0.000617268349064968, 0.000632975679951382, 0.000643904422677427, 0.000653775268094148, 0.000662225067910141, 0.26735354610469, 0.267515415990146, 0.26753155165617, 0.267553498616325, 0.267532284594615, 0.267510330320289, 0.000334158771646756, 0.000319032383145857, 0.000306074699839994, 0.000299153278494114, 0.000293956197852583, 0.000290171804454218, 0.000645975219899115, 0.000637548672578787, 0.000632375486965757, 0.000629579821884212, 0.000624956458229123, 0.000622456283217054, 0.0645188290106884, 0.0651539609630352, 0.0656417364889907, 0.0658996698322889, 0.0660715073023965, 0.0662034341510152), .Dim = c(6L, 12L)) Melt data: group variable value 1 1 PLDKRT 0 2 1 PLDKRT 0 3 1 PLDKRT 0 4 1 PLDKRT 0 5 1 PLDKRT 0 6 1 PLDKRT 0 Code: #Data_source 1 sensitivity_1=rbind(sensitivity_out1,sensitivity_out2) sensitivity_1=data.frame(sensitivity_1) colnames(sensitivity_1)=main_l #variable names sensitivity_1$group=1 #Data_source 2 sensitivity_2=rbind(sensitivity_out1[3:4,],sensitivity_out2[3:4,]) sensitivity_2=data.frame(sensitivity_2) colnames(sensitivity_2)=main_l sensitivity_2$group=2 sensitivity_pool=rbind(sensitivity_1,sensitivity_2) sensitivity_pool_m=melt(sensitivity_pool,id.vars="group") ggplot(data = sensitivity_pool_m, aes(x = variable, y = value)) + geom_boxplot(aes( fill= group), width = 0.8) Error: "Error in unit(tic_pos.c, "mm") : 'x' and 'units' must have length > 0" Update Figure out the error.

• Loading enumerations from database

  - by Mosh

  Hello, I have a problem with mapping .NET enumerations to database tables. Imagine I have a table called Statuses with the following values: StatusID | Name 1 Draft 2 Ready ... ... In the application layer, I can either use a Repository to get all Statuses as an IList object. However, the problem with this approach is that I cannot reference a certain status in my business logic. For example, how can I implement something like this? if (myObject.Status is Ready) do this else if (myObject.Status is Draft) do that... Since the statuses are loaded dynamically, I cannot tell for sure what particular Status object in the List represents the Draft or Ready status. Alternatively, I could just use an enumeration like public enum Statuses { Draft, Ready }; Then I could easily use an enumeration in my business logic. if (myObject.Status == Statuses.Draft) // do something... However, the problem with this approach is that every time the user wants to modify the list of Statuses (adding a new status, or renaming an existing status) the application has to be re-compiled. We cannot load the statuses dynamically from the database. Has anyone else come across a similar situation? Any solutions/patterns? Cheers, Mosh

• get static initialization block to run in a java without loading the class

  - by TP

  I have a few classes as shown here public class TrueFalseQuestion implements Question{ static{ QuestionFactory.registerType("TrueFalse", "Question"); } public TrueFalseQuestion(){} } ... public class QuestionFactory { static final HashMap<String, String > map = new HashMap<String,String>(); public static void registerType(String questionName, String ques ) { map.put(questionName, ques); } } public class FactoryTester { public static void main(String[] args) { System.out.println(QuestionFactory.map.size()); // This prints 0. I want it to print 1 } } How can I change TrueFalseQuestion Type so that the static method is always run so that I get 1 instead of 0 when I run my main method? I do not want any change in the main method. I am actually trying to implement the factory patterns where the subclasses register with the factory but i have simplified the code for this question.

• When do you trust the data / variables

  - by Wizzard

  We all know that all user data, GET/POST/Cookie etc etc needs to be validated for security. But when do you stop, once it's converted into a local variable? eg if (isValidxxx($_GET['foo']) == false) { throw InvalidArgumentException('Please enter a valid foo!'); } $foo = $_GET['foo']; fooProcessor($foo); function fooProcessor($foo) { if (isValidxxx($foo) == false) { throw Invalid...... } //other stuff } To me thats over the top. But what if you load the value from the database... I hope I make sense :)

• Passing variables to a Custom Zend Form Element

  - by user322003

  Hi, I'm trying to create a custom form element which extends Zend_Form_Element_Text with a validator (so I don't have to keep setting up the validator when I use certain elements). Anyway, I'm having trouble passing $maxChars variable to it when I instantiate it in my Main form. I've provided my shortened code below This is my custom element below class My_Form_Custom_Element extends Zend_Form_Element_Text { public $maxChars public function init() { $this->addValidator('StringLength', true, array(0, $this->maxChars)) } public function setProperties($maxChars) { $this->maxChars= $maxChars; } } This is where I instantiate my custom form element. class My_Form_Abc extends Zend_Form { public function __construct($options = null) { parent::__construct($options); $this->setName('abc'); $customElement = new My_Form_Custom_Element('myCustomElement'); $customElement->setProperties(100); //**<----This is where i set the $maxChars** $submit = new Zend_Form_Element_Submit('submit'); $submit -> setAttrib('id', 'submitbutton'); $this->addElements(array($customElement ,$submit)); } } When I try to pass '100' using $customElement-setProperties(100) in my Form, it doesnt get passed properly to my StringLength validator. I assume it's because the validator is getting called in Init? How can I fix this?

• CGLIB proxy error after spring bean definition loading into XmlWebApplicationContext at runtime

  - by VasylV

  I load additional singleton beans definitions at runtime from external jar file into existing XmlWebApplicationContext of my application: BeanFactory beanFactory = xmlWebApplicationContext.getBeanFactory(); DefaultListableBeanFactory defaultFactory = (DefaultListableBeanFactory)beanFactory; final URL url = new URL("external.jar"); final URL[] urls = {url}; ClassLoader loader = new URLClassLoader(urls, this.getClass().getClassLoader()); defaultFactory.setBeanClassLoader(loader); final ClassPathBeanDefinitionScanner scanner = new ClassPathBeanDefinitionScanner(defaultFactory); final DefaultResourceLoader resourceLoader = new DefaultResourceLoader(); resourceLoader.setClassLoader(loader); scanner.setResourceLoader(resourceLoader); scanner.scan("com.*"); Object bean = xmlWebApplicationContext.getBean("externalBean"); After all above xmlWebApplicationContext contains all external definitions of beans. But when i am trying to get bean from context exception is thrown: Couldn't generate CGLIB proxy for class ... I saw in debug mode that in the bean initialization process first time proxy is generated by org.springframework.aop.aspectj.autoproxy.AspectJAwareAdvisorAutoProxyCreator and than it is tried to generate proxy with org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator but fails with mentioned exception.

• Loading Jscript files into Firefox extension

  - by colon3l

  Hi ! Let's get directly to the problem : I'm actually doing a firefox extension in which i would like to implement the jWebsocket API in order to build a small chat. I got my main script file, named test.js, and the jWebsocket lib into a js folder. Just for you to know, this is my first firefox extension ever. So in my XUL file I got this (for the script part only of course, the interface code is not shown) : <overlay id="test-overlay" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="application/x-javascript" src="chrome://test/content/test.js" /> <script type="application/x-javascript" src="chrome://test/content/js/jwebsocket.js" /> jwebsocket.js being the file I need to call according to jWebsocket website. In my main script file test.js I start with : if (jws.browserSupportsWebSockets()) { jWebSocketClient = new jws.jWebSocketJSONClient(); } else { var lMsg = jws.MSG_WS_NOT_SUPPORTED; alert(lMsg); } jws being the namespace created into the jwebsocket.js file. Of course I've got the required stand-alone server running in background, and working. So from what I understood looking on various websites, is that if a js file is loaded into the javascript allocated memory space (with the tag), all namespace/function should be available between each file. But this was mostly for HTML-oriented issues, so I'm not sure if it applies to XUL/Firefox environment. But the script keep failing at the first jws call. Any ideas on what goes wrong here ? I'm stuck for 2 days now :/

• Loading zsh as the default shell in gnu screen

  - by joel

  Hello, Im using KUbuntu 10.04 (Lucid Lynx). I have installed zsh and screen. I have set zsh as the default shell, by setting Command to zsh in Settings-Edit Current Profile of the terminal. But,when i launch screen,the bash shell is loaded. If i run the command zsh, then zsh starts but the following message is displayed: "/home/joel/.zshrc:36: Can't add module parameter `mapfile': parameter already exists" Also,zsh is invoked for only the current screen instance and i have to invoke it manually again for other instances. So,is there any way to make screen load zsh by default and invoke it automatically for every instance ? Thank You

• Accessing ViewController's variables from UIActionSheet delegate

  - by VansFannel

  Hello. I have the following code: @implementation SendMapViewController NSMutableArray *emails; At this method I create emails array and I add some NSStrings: - (BOOL) peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson: (ABRecordRef)person { ABMultiValueRef emailInfo = ABRecordCopyValue(person, kABPersonEmailProperty); NSUInteger emailCount = ABMultiValueGetCount(emailInfo); if (emailCount > 1) { UIActionSheet *emailsAlert = [[UIActionSheet alloc] initWithTitle:@"Select an email" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; emails = [NSMutableArray arrayWithCapacity: emailCount]; for (NSUInteger i = 0; i < emailCount; i++) { NSString *emailFromContact = (NSString *)ABMultiValueCopyValueAtIndex(emailInfo, i); [emails addObject: emailFromContact]; [emailsAlert addButtonWithTitle:emailFromContact]; [emailFromContact release]; } [emailsAlert addButtonWithTitle:@"Cancel"]; [emailsAlert showInView:self.view]; [emailsAlert release]; } else { ... } CFRelease(emailInfo); [self dismissModalViewControllerAnimated:YES]; return NO; } As you can see in code, if there are more than one email I show and UIActionSheet. When user clicks on a button representing and email, I want to execute the following code: - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if ([emails count] >= buttonIndex) { NSString *contactEmail = (NSString *)[emails objectAtIndex:buttonIndex]; ... } } But emails array hasn't got any email. What I'm doing wrong? I'm developing for iPhone.

Also tried this with similar results... when I debug inside my usercontrol (pfd1) the parameters I am trying to set have not been set. uc = (UserControl)e.Item.FindControl("pfd1"); if (uc != null) { uc.Attributes.Add("ContainerID", _cid.ToString()); uc.Attributes.Add("ParentItemId", i.ItemID.ToString()); }

• jquery ui css not loading and creating poblems with asp.net mvc3 page (unexpected token error)

  - by giddy

  hi, So I suspect Im doing something silly, but first off, I can see that my mvc3 project already had jquery ui in it but no theme css files. I needed a date picked and as usual needed to override the EditorFor DateTime. I started off today by just using the default jquery ui js files supplied with the project under scripts. The date picker shows up fine, only with a completed messed up UI based on Site.css. So now I downloaded a build of jquery (with the start theme) and followed this page about how to put it together. Im using T4MVC so my page looks like this: Layout.cshtml : <script src="@Links.Scripts.jquery_1_4_4_js" type="text/javascript"></script> <link href="@Links.Content.Site_css" rel="stylesheet" type="text/css" /> <script src="@Links.Content.start.jquery_ui_1_8_7_custom_css" type="text/javascript"></script> Create.cshtml <script src="@Links.Scripts.jquery_validate_min_js" type="text/javascript"></script> <script src="@Links.Scripts.jquery_validate_unobtrusive_min_js" type="text/javascript"></script> <script src="@Links.Scripts.jquery_ui_1_8_7_custom_min_js" type="text/javascript"></script> And this is the result: Any ideas, Ive been googleing for a while now, I tried a couple combinations of where I put the script and css files tags in different places, but nothing seems to work.

• objective-c Novice - Needs help with global variables and setter method

  - by user544006

  I am creating a quiz app which has 2 views, MMAppViewController and a subview Level1View. I have declared NSInteger property "theScore" in the MMAppViewController view and have synthesised it. In my Level1View when they answer a correct question the "theScore" int will increase by one. The score has to be a global variable because when you reach so many points it will unlock the next level. For some reason in my switch statement it only lets me use the setTheScore method once. I am getting errors for every other set method in the switch statement. Error: "Duplicate label setTheScore". The statement is in the pushButtonAnswer method: setTheScore: theScore++; Here is my code: #import "Level1View.h" #import "MMAppViewController.h" @implementation Level1View @synthesize answer; @synthesize question; @synthesize userAnswer; @synthesize theScore; @synthesize score; int questionNum=0; NSInteger score=0; NSInteger theScore; BOOL start=FALSE; BOOL optionNum=FALSE; -(IBAction)pushBack{ [self dismissModalViewControllerAnimated:YES]; } -(IBAction)pushButton1{ optionNum=TRUE; labelAnswer.textColor=[UIColor blackColor]; userAnswer=@"1"; [labelAnswer setText:(@"You chose 'A'")]; } -(IBAction)pushButton2{ optionNum=TRUE; labelAnswer.textColor=[UIColor blackColor]; userAnswer=@"2"; [labelAnswer setText:(@"You chose 'B'")]; } -(IBAction)pushButton3{ optionNum=TRUE; labelAnswer.textColor=[UIColor blackColor]; userAnswer=@"3"; [labelAnswer setText:(@"You chose 'C'")]; } -(IBAction)pushButtonAnswer{ labelAnswer.textColor=[UIColor blackColor]; switch (questionNum){ case 1: if(answer==userAnswer && optionNum==TRUE){ labelAnswer.textColor=[UIColor greenColor]; [labelAnswer setText:(@"correct")]; [self hideButtons]; score++; [self setTheScore: theScore++]; } else if(optionNum==FALSE){ [labelAnswer setText:(@"Please choose an answer below:")];} else{ labelAnswer.textColor=[UIColor redColor]; [labelAnswer setText:(@"wrong")];} [self hideButtons]; break; case 2: if(answer==userAnswer && optionNum==TRUE){ labelAnswer.textColor=[UIColor greenColor]; [labelAnswer setText:(@"correct")]; [self hideButtons]; score++; [self setTheScore: theScore++]; } else if(optionNum==FALSE){ [labelAnswer setText:(@"Please choose an answer below:")];} else{ labelAnswer.textColor=[UIColor redColor]; [labelAnswer setText:(@"wrong")]; [self hideButtons];} break; case 3: if(answer==userAnswer && optionNum==TRUE){ labelAnswer.textColor=[UIColor greenColor]; .... And #import "MMAppViewController.h" #import "Level1View.h" @implementation MMAppViewController @synthesize theScore; NSInteger score; -(IBAction)pushLevel1{ Level1View *level1View = [[Level1View alloc] initWithNibName:nil bundle:nil]; [self presentModalViewController:level1View animated:YES]; theScore++; } -(IBAction)pushLevel2{ //Level1View *level1View = [[Level1View alloc] initWithNibName:nil bundle:nil]; //[self presentModalViewController:level1View animated:YES]; NSInteger *temp = Level1View.score; //int theScore=2; [labelChoose setText:[NSString stringWithFormat:@"You scored %i", theScore]]; } Does anyone know why i am getting these errors and if I am coding this correctly?

The standard way to do this is to add the links in the gridComplete callback like shown below: gridComplete: function() { var ids = jQuery("#jobs_table").jqGrid('getDataIDs'); for(var i=0;i < ids.length;i++){ var cl = ids[i]; be = '<%= link_to(image_tag("delete.gif", :border=>0, :size=>"20x22", :alt => "delete"),· { :action => 'destroy', :id => 'cl', :method => :delete}, :class => 'ajax') -%>'; jQuery("#jobs_table").jqGrid('setRowData',ids[i],{workflow_state:be}); } }, Using getDataIDs I get a list of IDs that I can use to generate the delete links. The problem is that this is a javascript call that results in a javascript variable. The question is how can I use this variable "cl" inside rails link_to view helper?

• Eclipse jvm.dll error when loading

  - by Dan James Palmer

  Trying to open Eclipse after a couple of months and get this error: So I checked that folder to see if it existed, and it did: I checked my PATH Was correct and it was also correct: When this error first occurred I had 3 Java installations. JRE 7 Update 10, JDK 7 Update 7 32bit and 64 bit. I uninstall ALL and restarted my machine. Eclipse then stated, as expected that I needed a JRE or a JDK. So I downloaded and installed the latest JDK and now I get this error, despite everything appearing to be correct. Any ideas?

• iOS TableView crash loading different data

  - by jollyr0ger

  Hi to all! I'm developing a simple iOS app where there is a table view with some categories (CategoryViewController). When clicking one of this category the view will be passed to a RecipesListController with another table view with recipes. This recipes are loaded from different plist based on the category clicked. The first time I click on a category, the recipes list is loaded and shown correctely. If i back to the category list and click any of the category (also the same again) the app crash. And I don't know how. The viewWillAppear is ececuted correctely but after crash. Can you help me? If you need the entire project I can zip it for you. Ok? Here is the code of the CategoryViewController.h #import <Foundation/Foundation.h> #import "RecipeRowViewController.h" @class RecipesListController; @interface CategoryViewController : UITableViewController { NSArray *recipeCategories;

• JQuery UI question, how do you add variables into the dialog box

  $('.openDialog').click(function(event){ var width=$(this).attr('width'); var height=$(this).attr('height'); alert(width + ' ' + height); event.preventDefault(); $("#dialog").dialog({autoOpen: false, modal: true}); $('#dialog').dialog('option', 'width', width); $('#dialog').dialog('open'); $('#dialog p').load('http://pagetoload.com/page.html .content'); }); As you can see above i'm trying to open a dialog box with a passed in parameter of width and height, however when I try and pass in the value of width on this line: $('#dialog').dialog('option', 'width', width); it doesn't work, any ideas why or how to get around that? Thanks

• Strange problems with PHP SOAP (private variable not persist + variables passed from client not work

  - by Tamas Gal

  I have a very strange problems in a PHP Soap implementation. I have a private variable in the Server class which contains the DB name for further reference. The private variable name is "fromdb". I have a public function on the soap server where I can set this variable. $client-setFromdb. When I call it form my client works perfectly and the fromdb private variable can be set. But a second soap client call this private variable loses its value... Here is my soap server setup: ini_set('soap.wsdl_cache_enabled', 0); ini_set('session.auto_start', 0); ini_set('always_populate_raw_post_data', 1); global $config_dir; session_start(); /*if(!$HTTP_RAW_POST_DATA){ $HTTP_RAW_POST_DATA = file_get_contents('php://input'); }*/ $server = new SoapServer("{$config_dir['template']}import.wsdl"); $server-setClass('import'); $server-setPersistence(SOAP_PERSISTENCE_SESSION); $server-handle(); Problem is that I passed this to the server: $client = new SoapClient('http://import.ingatlan.net/wsdl', array('trace' = 1)); $xml=''; $xml.=''; $xml.=''; $xml.=''; $xml.='Valaki'; $xml.=''; $xml.=''; $xml.=''; $xml.=''; $tarray = array("type" = 1, "xml" = $xml); try{ $s = $client-sendXml( $tarray ); print "$s"; } catch( SOAPFault $exception){ print "--- SOAP exception :{$exception}---"; print "LAST REQUEST :"; var_dump($client-_getLastRequest()); print "---"; print "LAST RESPONSE :".$client-_getLastResponse(); } So passed an Array of informations to the server. Then I got this exception: LAST REQUEST : <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><type>Array</type><xml/></SOAP-ENV:Body></SOAP-ENV:Envelope> Can you see the Array word between the type tag? Seems that the client only passed a reference or something like this. So I totaly missed :(

• Rails - eager load the number of associated records, but not the record themselves.

  - by Max Williams

  I have a page that's taking ages to render out. Half of the time (3 seconds) is spent on a .find call which has a bunch of eager-loaded associations. All i actually need is the number of associated records in each case, to display in a table: i don't need the actual records themselves. Is there a way to just eager load the count? Here's a simplified example: @subjects = Subject.find(:all, :include => [:questions]) In my table, for each row (ie each subject) i just show the values of the subject fields and the number of associated questions for each subject. Can i optimise the above find call to suit these requirements? I thought about using a group field but my full call has a few different associations included, with some second-order associations, so i don't think group by will work. @subjects = Subject.find(:all, :include => [{:questions => :tags}, {:quizzes => :tags}], :order => "subjects.name") :tags in this case is a second-order association, via taggings. Here's my associations in case it's not clear what's going on. Subject has_many :questions has_many :quizzes Question belongs_to :subject has_many :taggings has_many :tags, :through => :taggings Quiz belongs_to :subject has_many :taggings has_many :tags, :through => :taggings Grateful for any advice - max
