  • Django Database design -- Is this a good stragety for overriding defaults

    - by rh0dium
    Hi SO's I have a question on good database design practices and I would like to leverage you guys for pointers. The project started out simple. Hey we have a bunch of questions we want answered for every project (no problem) Which turned into... Hey we have so many questions can we group them into sections (yup we can do that) Which lead into.. Can we weight these questions and I don't really want some of these questions for my project (Yes but we are getting difficult) And then I'm thinking they will want to have each section have it's own weight.. Requirements So there's the requirements - For n number of project Allow a admin member the ability select the questions for a project Allow the admin member to re-weigh or use the default weights for the questions Allow the admin member to re-weight the sections Allow team members to answer the questions. So here is what I came up with. Please feel free to comment and provide better examples models.py from django.db import models from django.contrib.sites.models import Site from django.conf import settings class Section(models.Model): """ This describes the various sections for a checklist: """ name = models.CharField(max_length=64) description = models.TextField() class Question(models.Model): """ This simply provides a simple way to list out the questions. """ question = models.CharField(max_length=255) answer_type = models.CharField(max_length=16) description = models.TextField() section = models.ForeignKey(Section) class ProjectQuestion(models.Model): """ These are the questions relevant to the project """ question = models.ForeignKey(Question) answer = models.CharField(max_length=255) required = models.BooleanField(default=True) weight = models.FloatField(default = XXX) class Project(models.Model): """ Here is where we want to gather our questions """ questions = models.ManyToManyField(ProjectQuestion) Immediate questions: - When I start a project - any ideas on how to "pre-populate" the questions (and ultimately the weights) for the project? - Is there a generally accepted method for doing this process that I am missing? Basically the idea that you refer to the questions overide your own default weight, and store the answer? - It appears that a good chuck of the work will be done in the views and that a lot of checking will need to occur there? Is that OK? Again - feel free to give me better strategies!! Thanks

  • Join Query Not Working

    - by John
    Hello, I am using three MySQl tables: comment commentid loginid submissionid comment datecommented login loginid username password email actcode disabled activated created points submission submissionid loginid title url displayurl datesubmitted In these three tables, the "loginid" correspond. I would like to pull the top 10 loginids based on the number of "submissionid"s. I would like to display them in a 3-column HTML table that shows the "username" in the first column, the number of "submissionid"s in the second column, and the number of "commentid"s in the third column. I tried using the query below but it did not work. Any idea why not? Thanks in advance, John $sqlStr = "SELECT l.username ,l.loginid ,c.commentid ,count(s.commentid) countComments ,c.comment ,c.datecommented ,s.submissionid ,count(s.submissionid) countSubmissions ,s.title ,s.url ,s.displayurl ,s.datesubmitted FROM comment AS c INNER JOIN login AS l ON c.loginid = l.loginid INNER JOIN submission AS s ON c.loginid = s.loginid GROUP BY c.loginid ORDER BY countSubmissions DESC LIMIT 10"; $result = mysql_query($sqlStr); $arr = array(); echo "<table class=\"samplesrec1\">"; while ($row = mysql_fetch_array($result)) { echo '<tr>'; echo '<td class="sitename1"><a href="http://www...com/.../members/index.php?profile='.$row["username"].'">'.stripslashes($row["username"]).'</a></td>'; echo '</tr>'; echo '<td class="sitename1">'.stripslashes($row["countSubmissions"]).'</td>'; echo '</tr>'; echo '</tr>'; echo '<td class="sitename1">'.stripslashes($row["countComments"]).'</td>'; echo '</tr>'; } echo "</table>";

  • Display all the options if nothing is selected

    - by Levani
    I have four level connected dropdown boxes. I can choose something from second dropdown only after I select something from the first one. The third dropdown is also depended on second one and so on.

  • NSTimer to smooth out playback position

    - by Michael
    I have an audio player and I want to show the current time of the the playback. I'm using a custom play class. The app downloads the mp3 to a file then plays from the file when 5% has been downloaded. I have a progress view update as the file plays and update a label on each call to the progress view. However, this is jerky... sometimes even going backward a digit or two. I was considering using an NSTimer to smooth things out. I would be fired every second to a method and pass the percentage played figure to the method then update the label. First, does this seem reasonable? Second, how do I pass the percentage (a float) over to the target of the timer. Right now I am putting the percent played into a dictionary but this seems less than optimal. This is what is called update the progress bar: -(void)updateAudioProgress:(Percentage)percent { audio = percent; if (!seekChanging) slider.value = percent; NSMutableDictionary *myDictionary = [[NSMutableDictionary alloc] init]; [myDictionary setValue:[NSNumber numberWithFloat:percent] forKey:@"myPercent"]; [NSTimer scheduledTimerWithTimeInterval:5 target:self selector:@selector(myTimerMethod:) userInfo:myDictionary repeats:YES]; [myDictionary release]; } This is called first after 5 seconds but then updates each time the method is called. As always, comments and pointers appreciated.

  • Where'd my sounds go?

    - by Dane Man
    In my Row class I have the initWithCoder method and everything restored in that method works fine, but only within the method. After the method is called I loose an array of sounds that is in my Row class. The sounds class also has the initWithCoder method, and the sound plays fine but only in the Row class initWithCoder method. After decoding the Row object, the sound array disappears completely and is unable to be called. Here's my source for the initWithCoder: - (id) initWithCoder:(NSCoder *)coder { ... soundArray = [coder decodeObjectForKey:@"soundArray"]; NSLog(@"%d",[soundArray count]); return self; } the log shows the count as 8 like it should (this is while unarchiving). Then the row object I create gets assigned. And the resulting row object no longer has a soundArray. [NSKeyedArchiver archiveRootObject:row toFile:@"DefaultRow"]; ... row = [NSKeyedUnarchiver unarchiveObjectWithFile:@"DefaultRow"]; So now whenever I call the soundArray it crashes. //ERROR IS HERE NSLog(@"%d",[[row soundArray] count]); Help please (soundArray is an NSMutableArray).

  • div stacking/layout with css or javascript

    - by liz
    so i have 4 divs (i actually have many more but this will simplify the question). i want to display them in two columns. the 4 divs vary in height. the number of actual divs in the end will vary. so if i have this <div id="1" style="height: 200px" class="inline">some content here</div> <div id="2" style="height: 600px" class="inline">some content here</div> <div id="3" style="height: 300px" class="inline">some content here</div> <div id="4" style="height: 200px" class="inline">some content here</div> with styling thus .inline { display: inline-block; vertical-align: top; width: 48%;} so #1 would go left and then #2 would shove up beside it to the right, great, but the #3 will not slide up the 400px to fit nicely below #1. (of course)... it goes on the left side but at 600px from the top clearing the bottom of #2. etc... how would i get the divs to slide up into the empty spaces, is it possible with css? jquery maybe? i know i could write column divs to mark it up, but since the number of divs constantly change and the heights vary according to content. It would be nice to just get rid of the space since we dont really care about the order. any thoughts?

  • What's the pattern for a JSONP method that was initiated from a jQuery plugin?

    - by michielvoo
    I'm writing a jQuery plugin to render data retrieved from another domain in an element on the page. I follow the typical pattern for my jQuery plugin: $(selector).Plugin(options); In the plugin I get external data using jQuery.getScript(url, [success]). The external data source allows me to define the name of a method and it will wrap the data in a call to that method (JSONP): $.getScript("http://www.example.com/data?callback=global_callback", instance_callback); This effectively results in: <script type="text/javascript"> global_callback(data); </script> The scope of global_callback limits what the Plugin instance can do with the data. And the global_callback method has no knowledge of the selector or options that the plugin was instantiated with. I was thinking that global_callback would just store the data, and the plugin would retrieve the data in instance_callback. But I need to make sure that instance_callback will retrieve the correct data, I foresee a problem with multiple instances of the Plugin. How can I handle this? Thanks!

  • Calling method on category included from iPhone static library causes NSInvalidArgumentException

    - by Corey Floyd
    I have created a static library to house some of my code like categories. I have a category for UIViews in "UIView-Extensions.h" named Extensions. In this category I have a method called: - (void)fadeOutWithDelay:(CGFloat)delay duration:(CGFloat)duration; Calling this method works fine on the simulator on Debug configuration. However, if try to run the app on the device I get a NSInvalidArgumentException: [UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 It seems for some reason UIView-Extensions.h is not being included in the device builds. What I have checked/tried I did try to include another category for NSString, and had the same issue. Other files, like whole classes and functions work fine. It is an issue that only happens with categories. I did a clean all targets, which did not fix the problem. I checked the static library project, the categories are included in the target's "copy headers" and "compile sources" groups. The static library is included in the main projects "link binary with library" group. Another project I have added the static library to works just fine. I deleted and re-added the static library with no luck -ObjC linker flag is set Any ideas? nm output libFJSCodeDebug.a(UIView-Extensions.o): 000004d4 t -[UIView(Extensions) changeColor:withDelay:duration:] 00000000 t -[UIView(Extensions) fadeInWithDelay:duration:] 000000dc t -[UIView(Extensions) fadeOutWithDelay:duration:] 00000abc t -[UIView(Extensions) firstResponder] 000006b0 t -[UIView(Extensions) hasSubviewOfClass:] 00000870 t -[UIView(Extensions) hasSubviewOfClass:thatContainsPoint:] 000005cc t -[UIView(Extensions) rotate:] 000002d8 t -[UIView(Extensions) shrinkToSize:withDelay:duration:] 000001b8 t -[UIView(Extensions) translateToFrame:delay:duration:] U _CGAffineTransformRotate 000004a8 t _CGPointMake U _CGRectContainsPoint U _NSLog U _OBJC_CLASS_$_UIColor U _OBJC_CLASS_$_UIView U ___CFConstantStringClassReference U ___addsf3vfp U ___divdf3vfp U ___divsf3vfp U ___extendsfdf2vfp U ___muldf3vfp U ___truncdfsf2vfp U _objc_enumerationMutation U _objc_msgSend U _objc_msgSend_stret U dyld_stub_binding_helper

  • Why compiling in Flash IDE I cannot access stage in a Sprite constructor before addChild while if I

    - by yuri
    I've created this simple class (omissing package directive and imports) public class Viewer extends Sprite { public function Viewer():void { trace(stage); } } then in Flash IDE I import in first frame this AS: import Viewer var viewer = new Viewer(); stage.addChild(viewer); trace(viewer.stage); and this works as I expected: the first trace called in constructor say stage is "null" because I haven't yet add viewer to a DisplayObjectContainer. The second one output the stage object. So I created a project using AXDT eclipse plugin, I've recreated and compiled only the first class (trashed the AS init script used in Flash IDE because is not needed) and on the first trace ... wow ... the stage is filled with the stage Object. I seems to me that the compiler used by AXDT (Flex4 SDK open source) add the class... before construct it (!?).. to a DisplayObjectContainer already attached to a Stage. I want to understand how can reproduce this behaviour using compiler in Flash IDE so I can directrly access Stage in construction.

  • Python __subclasses__() not listing subclasses

    - by Mridang Agarwalla
    I cant seem to list all derived classes using the __subclasses__() method. Here's my directory layout: import.py backends __init__.py --digger __init__.py base.py test.py --plugins plugina_plugin.py From import.py i'm calling test.py. test.py in turn iterates over all the files in the plugins directory and loads all of them. test.py looks like this: import os import sys import re sys.path.append(os.path.join(os.path.abspath(os.path.dirname(os.path.abspath( __file__ ))))) sys.path.append(os.path.join(os.path.abspath(os.path.dirname(os.path.abspath( __file__ ))), 'plugins')) from base import BasePlugin class TestImport: def __init__(self): print 'heeeeello' PLUGIN_DIRECTORY = os.path.join(os.path.abspath(os.path.dirname(os.path.abspath( __file__ ))), 'plugins') for filename in os.listdir (PLUGIN_DIRECTORY): # Ignore subfolders if os.path.isdir (os.path.join(PLUGIN_DIRECTORY, filename)): continue else: if re.match(r".*?_plugin\.py$", filename): print ('Initialising plugin : ' + filename) __import__(re.sub(r".py", r"", filename)) print ('Plugin system initialized') print BasePlugin.__subclasses__() The problem us that the __subclasses__() method doesn't show any derived classes. All plugins in the plugins directory derive from a base class in the base.py file. base.py looks like this: class BasePlugin(object): """ Base """ def __init__(self): pass plugina_plugin.py looks like this: from base import BasePlugin class PluginA(BasePlugin): """ Plugin A """ def __init__(self): pass Could anyone help me out with this? Whatm am i doing wrong? I've racked my brains over this but I cant seem to figure it out Thanks.

  • C# app running as either Windows Form or as Console Application

    - by Aeolien
    I am looking to have one of my Windows Forms applications be run programmatically—from the command line. In preparation, I have separated the logic in its own class from the Form. Now I am stuck trying to get the application to switch back and forth based on the presence of command line arguments. Here is the code for the main class: static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { string[] args = Environment.GetCommandLineArgs(); if (args.Length > 1) // gets passed its path, by default { CommandLineWork(args); return; } Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } private static void CommandLineWork(string[] args) { Console.WriteLine("It works!"); Console.ReadLine(); } where Form1 is my form and the It works! string is just a placeholder for the actual logic. Right now, when running this from within Visual Studio (with command line arguments), the phrase It works! is printed to the Output. However, when running the /bin/Debug/Program.exe file (or /Release for that matter) the application crashes. Am I going about this the right way? Would it make more sense (i.e. take less developer time) to have my logic class be a DLL that gets loaded by two separate applications? Or is there something entirely different that I'm not aware of? Thanks in advance!

Check output console"); e.printStackTrace(); } } and the complete stacktrace of the above exception is: java.lang.ClassNotFoundException: com.mysql.jdbc:Driver at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:169) at mail.main(mail.java:114) Now, what's wrong I'm doing here?

  • C# reflection, cloning

    - by Enriquev
    Say I have this class Myclass that contains this method: public class MyClass { public int MyProperty { get; set; } public int MySecondProperty { get; set; } public MyOtherClass subClass { get; set; } public object clone<T>(object original, T emptyObj) { FieldInfo[] fis = this.GetType().GetFields(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic); object tempMyClass = Activator.CreateInstance(typeof(T)); foreach (FieldInfo fi in fis) { if (fi.FieldType.Namespace != original.GetType().Namespace) fi.SetValue(tempMyClass, fi.GetValue(original)); else fi.SetValue(tempMyClass, this.clone(fi.GetValue(original), fi.GetValue(original))); } return tempMyClass; } } Then this class: public class MyOtherClass { public int MyProperty777 { get; set; } } when I do this: MyClass a = new MyClass { MyProperty = 1, MySecondProperty = 2, subClass = new MyOtherClass() { MyProperty777 = -1 } }; MyClass b = a.clone(a, a) as MyClass; how come on the second call to clone, T is of type object and not of type MyOtherClass

  • iPhone slide view passing variables

    - by sebastyuiop
    Right, I'm trying to make an app that has a calculation that involves a stopwatch. When a button on the calculation view is clicked a stopwatch slides in from the bottom. This all works fine, the problem I can't get my head around is how to send the recorded time back to the previous controller to update a textfield. I've simplified the code and stripped out most irrelevant stuff. Many thanks. CalculationViewController.h #import <UIKit/UIKit.h> @interface CalculationViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> { IBOutlet UITextField *inputTxt; } @property (nonatomic, retain) UITextField *inputTxt; - (IBAction)showTimer:(id)sender; @end CalculationViewController.m #import "CalculationViewController.h" #import "TimerViewController.h" @implementation CalculationViewController - (IBAction)showTimer:(id)sender { TimerViewController *timerView = [[TimerViewController alloc] init]; [self.navigationController presentModalViewController:timerView animated:YES]; } TimerViewController.h #import <UIKit/UIKit.h> @interface TimerViewController : UIViewController { IBOutlet UILabel *time; NSTimer *myTicker; } - (IBAction)start; - (IBAction)stop; - (IBAction)reset; - (void)showActivity; @end TimerViewController.m #import "TimerViewController.h" #import "CalculationViewController.h" @implementation TimerViewController - (IBAction)start { myTicker = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(showActivity) userInfo:nil repeats:YES]; } - (IBAction)stop { [myTicker invalidate]; #Update inputTxt on calculation view here [self dismissModalViewControllerAnimated:YES]; } - (IBAction)reset { time.text = @"0"; } - (void)showActivity { int currentTime = [time.text intValue]; int newTime = currentTime + 1; time.text = [NSString stringWithFormat:@"%d", newTime]; } @end

  • Java generic Comparable where subclasses can't compare to eachother

    - by dege
    public abstract class MyAbs implements Comparable<MyAbs> This would work but then I would be able to compare class A and B with each other if they both extend MyAbs. What I want to accomplish however is the exact opposite. So does anyone know a way to get the generic type to be the own class? Seemed like such a simple thing at first... Edit: To explain it a little further with an example. Say you have an abstract class animals, then you extend it with Dogs and ants. I wouldn't want to compare ants with Dogs but I however would want to compare one dog with another. The dog might have a variable saying what color it is and that is what I want to use in the compareTo method. However when it comes to ants I would rather want to compare ant's size than their color. Hope that clears it up. Could possibly be a design flaw however.

  • VS2010 Implement Generic Interface expansion doesn't use specified type

    - by TJB
    Using the release version of Visual Studio 2010 I think there's a difference in the "Implement Interface" expansion from VS2008 If I speicify an interface and implement it in a class as so: public interface IRepository<T> where T : IModel { T Get<T>(int id); void Update<T>(); int Add<T>(T item); } public class MockRepository : IRepository<MockUser> { // ... } Then use the "Implement Interface" expansion and get this: public class MockRepository : IRepository<MockUser> { public T Get<T>(int id) { throw new NotImplementedException(); } public void Update<T>() { throw new NotImplementedException(); } public int Add<T>(T item) { throw new NotImplementedException(); } } Instead of what I expected public class MockRepository : IRepository<MockUser> { public MockUser Get<MockUser>(int id) { throw new NotImplementedException(); } public void Update<MockUser>() { throw new NotImplementedException(); } public int Add<MockUser>(MockUser item) { throw new NotImplementedException(); } } The IDE uses the type variable name from the generic interface definition T instead of the specified concrete type MockUser. Is this a bug? Or is something new just for VS2010 / .Net 4.0?

  • how to number t-rows ,when table generated using nested forloop in django templates

    - by stackover
    Hi, This part is from views.py results=[(A,[stuObj1,stuObj2,stuObj3]),(B,[stuObj4,stuObj5,stuObj6]),(C,[stuObj7,stuObj8])] for tup in results: total = tot+len(tup[1]) render_to_response(url,{'results':res , 'total':str(tot),}) this is template code: <th class="name">Name</th> <th class="id">Student ID</th> <th class="grade">Grade</th> {% for tup in results %} {% for student in tup|last %} {% with forloop.parentloop.counter as parentid%} {% with forloop.counter as centerid%} <tbody class="results-body"> <tr> <td>{{student.fname|lower|capfirst}} {{student.lname|lower|capfirst}}</td> <td>{{student.id}}</td> <td>{{tup|first}}</td> </tr> {% endfor %} {% endfor %} Now the problems am having are 1. numbering the rows. Here my problem is am not sure if i can do things like total=total-1 in the templates to get the numbered rows like <td>{{total}}</td> 2.applying css to tr:ever or odd. Whats happening in this case is everytime the loop is running the odd/even ordering is lost. these seems related problems. Any ideas would be great :)

  • Switching from form_for to remote_form_for problems with submit changes in Rails

    - by Matthias Günther
    Hi there, another day with Rails and today I want to use Ajax. linkt_remote_link for changing a text was pretty easy so I thought it would also be easy to switch my form_for loop just to an ajax request form with remote_form_for, but the problem with the remote_form_for is that it doesn't save my changes? Here the code that worked: <% form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> Here the code which don't save me the changes and submit them: <% remote_form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post" onsubmit="$.ajax({data:$.param($(this).serializeArray()), dataType:'script', type:'post', url:'/adminbill/update/58'}); return false;"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> I don't know if I have to consider something special when using remote_form_for (see remote_form_for)

  • Separating Content (aspx) from Code (aspx.cs) in ASP.NET

    - by firedrawndagger
    I would like to know what is the best practice on separating the content of an aspx page (ASP.NET 3.5) from the code (I'm using C#). I have a form that users can type data in - for example they are allowed to enter a percent. If they Otherwise for example I would like to display the following error messages: <p id="errormsg" class="percenthigh">Please enter a percent below 100</p> <p id="errormsg" class="percentnegative">Percent cannot be below 0</p> <p id="errormsg" class="percentnot">This is not a percent</p> So in essence I'm hiding the error messages and showing one depending on what the user input is. I believe this is the best way to seperate the content from the code behind. However, how do I select elements and hide/unhide them depending on the user input? I'm aware I can do a runat="server" on the elements but the problem is that I can't select by class and am limited only to ID's. What workarounds do you recommend? Aside from putting in the values in code behind which is notoriously difficult to debug. Also has this been "fixed" in ASP.NET 4?

  • Accessing jQuery objects in the module pattern

    - by Stewart
    Hello, Really getting in to javascript and looking around at some patterns. One I have come accross is the module pattern. Its seems like a nice way to think of chucks of functionality so I went ahead and tried to implement it with jQuery. I ran in to a snag though. Consider the following code <!DOCTYPE html> <html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8"> <title>index</title> <script type="text/javascript" charset="utf-8" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script> <script type="text/javascript" charset="utf-8"> $(document).ready(function(){ var TestClass2 = (function(){ var someDiv; return { thisTest: function () { someDiv = document.createElement("div"); $(someDiv).append("#index"); $(someDiv).html("hello"); $(someDiv).addClass("test_class"); } } })(); TestClass2.thisTest(); }); </script> </head> <body id="index" onload=""> <div id="name"> this is content </div> </body> </html> The above code alerts the html content of the div and then adds a class. These both use jQuery methods. The problem is that the .html() method works fine however i can not add the class. No errors result and the class does not get added. What is happening here? Why is the class not getting added to the div?
