  • JQuery Cycle fails on Page Refresh

    - by Darknight
    In a similar issue as this one: http://stackoverflow.com/questions/1719475/jquery-cycle-firefox-squishing-images I've managed to overcome the initial problem using Jeffs answer in the above link. However now I have noticed a new bug, upon page refresh it simply does not work. I have tried a hard refresh (ctrl+F5) but this does not work. However when you come page to the page it loads fine. here is my modified version (taken from Jeff's): <script type="text/javascript"> $(document).ready(function() { var imagesRemaining = $('#slideshow img').length; $('#slideshow img').bind('load', function(e) { imagesRemaining = imagesRemaining - 1; if (imagesRemaining == 0) { $('#slideshow').show(); $('#slideshow').cycle({ fx: 'shuffle', speed: 1200 }); } }); }); </script> Any ideas? I've also tried JQuery Live but could not implement it correctly. I've also tried Meta tags to force images to load. But it only works first time round.

  • Prototype's Ajax.Updater not actually updating on IE7.

    - by Ben S
    I am trying to submit a form using Ajax.Updater and have the result of that update a div element in my page. Everything works great in IE6, FF3, Chrome and Opera. However, In IE7 it sporadically works, but more often than not, it just doesn't seem to do anything. Here's the javascript: function testcaseHistoryUpdate(testcase, form) { document.body.style.cursor = 'wait'; var param = Form.serialize(form); new Ajax.Updater("content", "results/testcaseHistory/" + testcase, { onComplete: function(transport) {document.body.style.cursor = 'auto'}, parameters: param, method: 'post' } ); } I've verified using alert() calls that param is set to what I expect. I've read in many places that IE7 caches aggressively and that it might be the root cause, however every after adding the following to my php response, it still doesn't work. header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); To further try to fix a caching issue I've tried adding a bogus parameter which just gets filled with a random value to have different parameters for every call, but that didn't help. I've also found this, where UTF-8 seemed to be causing an issue with IE7, but my page is clearly marked: <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> Does anyone have any idea what could be wrong with IE7 as opposed to the other browsers I tested to cause this kind of issue?

  • "Public" nested classes or not

    - by Frederick
    Suppose I have a class 'Application'. In order to be initialised it takes certain settings in the constructor. Let's also assume that the number of settings is so many that it's compelling to place them in a class of their own. Compare the following two implementations of this scenario. Implementation 1: class Application { Application(ApplicationSettings settings) { //Do initialisation here } } class ApplicationSettings { //Settings related methods and properties here } Implementation 2: class Application { Application(Application.Settings settings) { //Do initialisation here } class Settings { //Settings related methods and properties here } } To me, the second approach is very much preferable. It is more readable because it strongly emphasises the relation between the two classes. When I write code to instantiate Application class anywhere, the second approach is going to look prettier. Now just imagine the Settings class itself in turn had some similarly "related" class and that class in turn did so too. Go only three such levels and the class naming gets out out of hand in the 'non-nested' case. If you nest, however, things still stay elegant. Despite the above, I've read people saying on StackOverflow that nested classes are justified only if they're not visible to the outside world; that is if they are used only for the internal implementation of the containing class. The commonly cited objection is bloating the size of containing class's source file, but partial classes is the perfect solution for that problem. My question is, why are we wary of the "publicly exposed" use of nested classes? Are there any other arguments against such use?

  • PHP get "Application Root" in Xampp on Windows correctly

    - by Michael Mao
    Hi all: I found this thread on StackOverflow about how to get the "Application Root" from inside my web app. However, most of the approaches suggested in that thread can hardly be applied to my Xampp on Windows. Say, I've got a "common.php" which stays inside my web app's app directory: / /app/common.php /protected/index.php In my common.php, what I've got is like this: define('DOCROOT', $_SERVER['DOCUMENT_ROOT']); define('ABSPATH', dirname(__FILE__)); define('COMMONSCRIPT', $_SERVER['PHP_SELF']); After I required the common.php inside the /protected/index.php, I found this: C:/xampp/htdocs //<== echo DOCROOT; C:\xampp\htdocs\comic\app //<== echo ABSPATH /comic/protected/index.php //<== echo COMMONSCRIPT So the most troublesome part is the path delimiters are not universal, plus, it seems all superglobals from the $_SERVER[] asso array, such as $_SERVER['PHP_SELF'], are relative to the "caller" script, not the "callee" script. It seems that I can only rely on dirname(__FILE__) to make sure this always returns an absolute path to the common.php file. I can certainly parse the returning values from DOCROOT and ABSPATH and then calculate the correct "application root". For instance, I can compare the parts after htdocs and substitute all backslashes with slashes to get a unix-like path I wonder is this the right way to handle this? What if I deploy my web app on a LAMP environment? would this environment-dependent approach bomb me out? I have used some PHP frameworks such as CakePHP and CodeIgniter, to be frank, They just work on either LAMP or WAMP, but I am not sure how they approached such a elegant solution. Many thanks in advance for all the hints and suggestions.

  • Why are my descenders being cut off when using CSS @font-face?

    - by Olly Hodgson
    I'm using the Google webfonts API to embed Droid Sans on a page. All is fine, except for the descenders (i.e. the dangly bits on y, g, etc). The latest versions of Firefox, IE and Chrome on my Windows Vista box are all cutting the bottom off. <!DOCTYPE html> <html> <head> <title>Droid sans descender test</title> <meta charset="utf-8"> <link href="http://fonts.googleapis.com/css?family=Droid+Sans:regular,bold" rel="stylesheet" type="text/css"> <style type="text/css"> body { font-size: 16px; font-family: "Droid Sans"sans-serif; } h1, h2, h3 { margin: 1em 0; font-weight: normal; } h1 { font-size: 2em; } h2 { font-size: 1.5em; } h3 { font-size: 1em; } </style> </head> <body> <h1>A bug ran under the carpet anyway</h1> <h2>A bug ran under the carpet anyway</h2> <h3>A bug ran under the carpet anyway</h3> </body> </html> The above code looks like this: I've tried line-height, font-size, padding etc to no avail. I had some success with font-size-adjust, but the last time I checked it was Gecko only. Does anybody know of a fix for this?

  • jitter if multiple outliers in ggplot2 boxplot

    - by Andreas
    I am trying to find a suitable display to illustrate various properties within and across school classes. For each class there is only 15-30 data points (pupils). Right now i am leaning towards a whisker-less boxplot, showing only 1.,2. and 3. quartile + datapoints more then e.g. 1 population SD +/- the sample median. This I can do. However - I need to show this graph to some teachers, in order to gauge what they like most. I'd like to compare my graph with a normal boxplot. But the normal boxplot looks the same if there is only one outlier, or e.g. 5 outliers at the same value. In this case this would be a deal-breaker. e.g. test <-structure(list(value = c(3, 5, 3, 3, 6, 4, 5, 4, 6, 4, 6, 4, 4, 6, 5, 3, 3, 4, 4, 4, 3, 4, 4, 4, 3, 4, 5, 6, 6, 4, 3, 5, 4, 6, 5, 6, 4, 5, 5, 3, 4, 4, 6, 4, 4, 5, 5, 3, 4, 5, 8, 8, 8, 8, 9, 6, 6, 7, 6, 9), places = structure(c(1L, 2L, 1L, 1L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 2L, 2L, 2L, 2L, 1L, 1L, 2L, 2L, 2L, 1L, 2L, 1L, 1L, 1L, 1L, 2L, 1L, 2L, 1L, 2L, 2L, 2L, 1L, 2L, 1L, 2L, 2L, 1L, 1L, 2L, 2L, 1L, 1L, 1L, 1L, 2L, 1L, 1L, 2L, 2L, 2L, 1L, 1L, 2L, 2L, 1L, 2L, 1L), .Label = c("a", "b"), class = "factor")), .Names = c("value", "places"), row.names = c(NA, -60L), class = "data.frame") ggplot(test, aes(x=places,y=value))+geom_boxplot() Here there are two outliers at ("a",9) - but only one "dot" shown. So my question: How to jitter the outliers. And - what kind of display would you suggest for this kind of data?

  • PHP Performance Metrics

    - by bigstylee
    I am currently developing a PHP MVC Framework for a personal project. While I am developing the framework I am interested to see any notable performance by implementing different techniques for optimization. I have implemented a crude BenchMark class that logs mircotime. The problem is I have no frame of reference for execution times. I am very near the beginnig of this project with a database connection and a few queries but no output (bar some debugging text and BenchMark log). I have a current execution time of 0.01917 seconds. I was expecting this to be lower but as I said before I have no frame of reference. I appreciate there are many variables to take into account when juding performance but I am hoping to find some sort of metric to a) techniques to measure performance for example requests per second and b) compare results for example; how a "moderately" sized PHP application on a "standard" webserver will perform. I appreciate "moderately" and "standard" are very subjective words so perhaps a table of known execution times for a particular application (eg StackOverFlow's executing time). What are other techniques of measuring performance are there other than execution time? When looking at MVC Framework Performance Comparisom it talks about Requests Per Second (RPS). How is this calculated? I am guessing with my current execution time of 0.01917 seconds can handle 52 RPS (= 1 / 0.01917 ). This seems to be significantly lower than that quoted on the graph especially when you consider my current limited funcitonality.

  • Sending wordpress title-value across PHP-pages

    - by VoodooBurger
    I recently made this wordpress blog, where you can sign up a team for an event, when clicking a link under the event post. This link takes you to a sign-up form on another php-page. The link is added in the loop of the events-template like this: <?php query_posts('cat=8');?> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <div class="post" id="post-<?php the_ID(); ?>"> <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2> <div id="tilmeldknap"><?php wp_list_pages("title_li=&depth=1&include=63"); ?></div> <?php include (TEMPLATEPATH . '/inc/meta.php' ); ?>... So every upcoming event will have the same sign-up button. All I need now is to somehow send the specific event-post-title along to the sign-page, so that the following form-submit action will contain that title aswell. But since I'm not very good at php it seems like a mystery, altho I bet it's very simple! I'm guessing it's something like: $event=$_POST['single_post_title()'] But how to get the value to the next php-page I have no idea... please help, anyone :) An eksample can be seen throught this link: http://gadebold.dk/events/ The link sais: 'Tilmeld Hold'

  • Sharepoint BDC Error: The title property of entity tblStaff is set to an invalid value

    - by Christopher Rathermel
    I am just starting to create our Business Data Catalog(s) for our practice management system and I am running into an issue w/ our staff table. Background: I am using Business Data Catalog Definition Editor to create my ADF. I am using the RevertToSelf Authentication Mode. I have tried a few other tables and they seem to work just fine thus far.. only issue is w/ the staff table. If I removed all the columns for the staff entity except the ID and a few columns for the name it actually works. So it has a problem w/ one of my columns in tblStaff. I receive this error even when I set up an ADF w/ just this one entity. So w/ no associations.. When attempting to view the record: http://servername/ssp/admin/Content/tblstaff.aspx?StaffID={0} w/ {0} replaced w/ an actual staff ID I get the following error: The title property of entity tblStaff is set to an invalid value. Things I have tried: I noticed that I do have a column in my staff table called "Title" and removed it from ADF w/ no luck... Same error.. I tried to use bdc meta man to create my ADF and I got the same error... Any ideas? Chris

  • Sorting by dates (including nil) with NSFetchedResultsController

    - by glorifiedHacker
    In my NSFetchedResultsController, I set a sortDescriptor that sorts based on the date property of my managed objects. The problem that I have encountered (along with several others according to Google) is that nil values are sorted at the earliest end rather than the latest end of the date spectrum. I want my list to be sorted earliest, earlier, now, later, latest, nil. As I understand it, this sorting is done at the database level in SQLite and so I cannot construct my own compare: method to provide the sorting I want. I don't want to manually sort in memory, because I would have to give up all of the benefits of NSFetchedResultsController. I can't do compound sorting because the sectionNameKeyPaths are tightly coupled to the date ranges. I could write a routine that redirects indexPath requests so that section 0 in the results controller gets mapped to the last section of the tableView, but I fear that would add a lot of overhead, severely increase the complexity of my code, and be very, very error-prone. The latest idea that I am considering is to map all nil dates to the furthest future date that NSDate supports. My left brain hates this idea, as it feels more like a hack. It will also take a bit of work to implement, since checking for nil factors heavily into how I process dates in my app. I don't want to go this route without first checking for better options. Can anyone think of a better way to get around this problem?

  • using jquery (json) to get ajax database entries in wordpress - PHP not working

    - by Matt Facer
    I'm writing a plugin for my wordpress site and am having trouble understanding the jquery ajax requests. In a nutshell, I am trying to get some user meta data loaded when the page loads. So in my javascript file I have a line: $.getJSON("http://mysite.co.uk/wp-content/plugins/myplugin/ajax/ajax.php?action=test", function(json) { // do stuff }); So the above DOES get called, but it's the PHP code I'm having trouble with. In the file ajax.php, I am making a database call, but NONE of the usual class information is available. I've tried including the admin ajax page, various other pages from my own plugin (which does work).... not sure what else to do! The database call method works OK in my plugin code.. but I guess that the ajax.php file is outside the WP framework so that's why it's not working... but I don't know how to get it IN the framework!? I just need to use the $wpdb->get_results($sql); command to get my SQL. The error returned from firebug is that I am making a call to an undefined function. Thanks for any help... $.getJSON("http://www.offbeatattractions.co.uk/wp-content/plugins/wp-geo-extended/ajax/change_location.php?action=listpoints", function(json) { alert(json.Locations.length);

  • What does stdole.dll do?

    - by rc1
    We have a large C# (.net 2.0) app which uses our own C++ COM component and a 3rd party fingerprint scanner library also accessed via COM. We ran into an issue where in production some events from the fingerprint library do not get fired into the C# app, although events from our own C++ COM component fired and were received just fine. Using MSINFO32 to compare the loaded modules on a working system to those on a failing system we determined that this was caused by STDOLE.DLL not being in the GAC and hence not loaded into the faulty process. Dragging this file into the GAC caused events to come back fine from the fingerprint COM library. So what does stdole.dll do? It's 16k in size so it can't be much... is it some sort of link to another library like STDOLE32? How come its absence causes such odd behavior? How do we distribute stdole.dll? This is an XCOPY deploy app and we don't use the GAC. Should we package it as a resource and use the System.EnterpriseServices.Internal.Publish.GacInstall to ensure it's in the GAC?

  • CakePHP: email validate action doesn't work when clicking on the email link

    - by bakerjr
    Hi, We've created the email validation part of our site. We built the site using CakePHP BTW. The problem is that it doesn't work when we click on the link in the email. The email is sent as plain text. A weird thing is that when we paste the link on the address bar, it works. Also when clicking on the link using Gmail and desktop email clients, it works as well. Other email providers doesn't work. EDIT: Additional info: Example link for the validation: http://localhost/users/validate/validatecodeblah12c023 When it's working it should login the user and redirect to the user dashboard. It goes to the front page when it's not working (see description above). Additional info 2: I did compare the results using Live HTTP headers and I found out that the only time it doesn't push through (goes to the login page for some reason) is when there's a 'Referrer: h ttp://mail.yahooblahblah...' Gmail for some reason doesn't have a 'Referer' line in it's headers.

  • Asp.net Crawler Webresponse Operation Timed out.

    - by Leon
    Hi I have built a simple threadpool based web crawler within my web application. Its job is to crawl its own application space and build a Lucene index of every valid web page and their meta content. Here's the problem. When I run the crawler from a debug server instance of Visual Studio Express, and provide the starting instance as the IIS url, it works fine. However, when I do not provide the IIS instance and it takes its own url to start the crawl process(ie. crawling its own domain space), I get hit by operation timed out exception on the Webresponse statement. Could someone please guide me into what I should or should not be doing here? Here is my code for fetching the page. It is executed in the multithreaded environment. private static string GetWebText(string url) { string htmlText = ""; HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url); request.UserAgent = "My Crawler"; using (WebResponse response = request.GetResponse()) { using (Stream stream = response.GetResponseStream()) { using (StreamReader reader = new StreamReader(stream)) { htmlText = reader.ReadToEnd(); } } } return htmlText; } And the following is my stacktrace: at System.Net.HttpWebRequest.GetResponse() at CSharpCrawler.Crawler.GetWebText(String url) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 366 at CSharpCrawler.Crawler.CrawlPage(String url, List1 threadCityList) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 105 at CSharpCrawler.Crawler.CrawlSiteBuildIndex(String hostUrl, String urlToBeginSearchFrom, List1 threadCityList) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 89 at crawler_Default.threadedCrawlSiteBuildIndex(Object threadedCrawlerObj) in c:\myAppDev\myApp\site\crawler\Default.aspx.cs:line 108 at System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object state) at System.Threading.ExecutionContext.runTryCode(Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem() at System.Threading.ThreadPoolWorkQueue.Dispatch() at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback() Thanks and cheers, Leon.

  • Java - abstract class, equals(), and two subclasses

    - by msr
    Hello, I have an abstract class named Xpto and two subclasses that extend it named Person and Car. I have also a class named Test with main() and a method foo() that verifies if two persons or cars (or any object of a class that extends Xpto) are equals. Thus, I redefined equals() in both Person and Car classes. Two persons are equal when they have the same name and two cars are equal when they have the same registration. However, when I call foo() in the Test class I always get "false". I understand why: the equals() is not redefined in Xpto abstract class. So... how can I compare two persons or cars (or any object of a class that extends Xpto) in that foo() method? In summary, this is the code I have: public abstract class Xpto { } public class Person extends Xpto{ protected String name; public Person(String name){ this.name = name; } public boolean equals(Person p){ System.out.println("Person equals()?"); return this.name.compareTo(p.name) == 0 ? true : false; } } public class Car extends Xpto{ protected String registration; public Car(String registration){ this.registration = registration; } public boolean equals(Car car){ System.out.println("Car equals()?"); return this.registration.compareTo(car.registration) == 0 ? true : false; } } public class Teste { public static void foo(Xpto xpto1, Xpto xpto2){ if(xpto1.equals(xpto2)) System.out.println("xpto1.equals(xpto2) -> true"); else System.out.println("xpto1.equals(xpto2) -> false"); } public static void main(String argv[]){ Car c1 = new Car("ABC"); Car c2 = new Car("DEF"); Person p1 = new Person("Manel"); Person p2 = new Person("Manel"); foo(p1,p2); } }

  • Advice on improving programming skills, learning capabilities?

    - by anonymous-coward1234
    Hi all, After 2,5 years of professional Java programing, I still have problems that make my job difficult and, more importantly - more times that I would like to admit - not enjoyable. I would like to ask for advice by more experienced people on ways that would help me overcome them. These are the problems I have: I do not absorb new knowledge easily. Even when I understand something, after a couple of days I easily forget even basic stuff. Other co-workers, even with the same working experience, when reading new technologies put things easily into "context", and are able to compare in "real time| similar technologies they already have used. I always try to address all the issues to whatever I am doing at one go, which results in me trying to resolve too many problems at the same time, losing completely control. I find it difficult to make my mind on a single problem that I should address first, and even when I do, and find myself throwing away code that I wrote because I started addressing the wrong issue first. As far as architecture and data modeling is concerned, I have difficulty making decisions on what objects must be created, with what hierarchy, interfaces, abstraction etc. I imagine that - to a certain degree - these things come with experience. But after 2,5 years of Java programming, I would expect myself to have come much farther that I have come, both in terms of absorption and experience. Is there a way to improve my learning speed? Any books, methods, advice is welcome.

  • Connecting to a self hosted WCF service from a Flex application - policy issues

    - by James S
    Hello, I am trying to accomplish the following: I wrote a Flex application that is trying to connect to a WCF service hosted on the clients computer. I also wrote a windows forms application for the client to run. This application exposes a self-hosted WCF service that the Flex application is supposed to connect to. This works fine if I'm loading the Flex application from my local IIS. The problem starts when the Flex application is hosted on a different domain. When this occurs, the flash player requires a crossdomain.xml policy file on the clients computer. I also managed to expose the crossdomain.xml on the clients computer using another WCF self-hosted service and WebHttpBinding on the clients computer. This also works fine. My problem is that the flash player requires that the crossdomain.xml or a meta policy file will be in the root directory of the domain. If I used my WCF service to expose something on the root directory of the clients computer I will run over any existing web server capabilities the client has on the computer (such as IIS). I know it's a bit complicated scenario, but any help would be appreciated. Thanks!

  • What's it like being a financial programmer?

    - by Mike
    As a student who's done an internship at a Silicon Valley company(non-financial), I'm curious to know what it's like working for a financial company doing software development. I'd expect the hours to be longer, and the pay to be higher. Specifically, I have the following questions: What's the work/life balance really like? Are you expected to work 80 hours a week most weeks? For those who have worked in non-financial software engineering jobs, how does being a financial software engineer compare in terms of work/life balance? How much does it pay? I'm curious as to starting(i.e. just got a BS) pay, as well as "top out" pay. (I'd prefer concrete numbers - ballpark is fine). Also, bonuses would be useful information. What jobs do financial programmers typically have? Are most just general software engineers, or do people typically have very specialized(i.e. AI or systems) backgrounds? Also, do most programmers have PhDs? Are programmers typically required to be at work, or are financial companies generally flexible about letting programmers work from home? When at work, do programmers have to dress formally? What are the technology environments like? Are finance companies using state-of-the-art hardware and software, or are they generally more conservative in upgrading their equipment? What programming languages are typically used? If VBA(shudder) is used, is it a large part of a finance company's workflow? If you could turn back the clock, would you still be a financial programmer? I'm going to keep this post open a little bit longer to get some more responses.

  • CharField values disappearing after save (readonly field)

    - by jamida
    I'm implementing simple "grade book" application where the teacher would be able to update the grades w/o being allowed to change the students' names (at least not on the update grade page). To do this I'm using one of the read-only tricks, the simplest one. The problem is that after the SUBMIT the view is re-displayed with 'blank' values for the students. I'd like the students' names to re-appear. Below is the simplest example that exhibits this problem. (This is poor DB design, I know, I've extracted just the relevant parts of the code to showcase the problem. In the real example, student is in its own table but the problem still exists there.) models.py class Grade1(models.Model): student = models.CharField(max_length=50, unique=True) finalGrade = models.CharField(max_length=3) class Grade1OForm(ModelForm): student = forms.CharField(max_length=50, required=False) def __init__(self, *args, **kwargs): super(Grade1OForm,self).__init__(*args, **kwargs) instance = getattr(self, 'instance', None) if instance and instance.id: self.fields['student'].widget.attrs['readonly'] = True self.fields['student'].widget.attrs['disabled'] = 'disabled' def clean_student(self): instance = getattr(self,'instance',None) if instance: return instance.student else: return self.cleaned_data.get('student',None) class Meta: model=Grade1 views.py from django.forms.models import modelformset_factory def modifyAllGrades1(request): gradeFormSetFactory = modelformset_factory(Grade1, form=Grade1OForm, extra=0) studentQueryset = Grade1.objects.all() if request.method=='POST': myGradeFormSet = gradeFormSetFactory(request.POST, queryset=studentQueryset) if myGradeFormSet.is_valid(): myGradeFormSet.save() info = "successfully modified" else: myGradeFormSet = gradeFormSetFactory(queryset=studentQueryset) return render_to_response('grades/modifyAllGrades.html',locals()) template <p>{{ info }}</p> <form method="POST" action=""> <table> {{ myGradeFormSet.management_form }} {% for myform in myGradeFormSet.forms %} {# myform.as_table #} <tr> {% for field in myform %} <td> {{ field }} {{ field.errors }} </td> {% endfor %} </tr> {% endfor %} </table> <input type="submit" value="Submit"> </form>

  • What's the best practice to setup testing for ASP.Net MVC? What to use/process/etc?

    - by melaos
    hi there, i'm trying to learn how to properly setup testing for an ASP.Net MVC. and from what i've been reading here and there thus far, the definition of legacy code kind of piques my interests, where it mentions that legacy codes are any codes without unit tests. so i did my project in a hurry not having the time to properly setup unit tests for the app and i'm still learning how to properly do TDD and unit testing at the same time. then i came upon selenium IDE/RC and was using it to test on the browser end. it was during that time too that i came upon the concept of integration testing, so from my understanding it seems that unit testing should be done to define the test and basic assumptions of each function, and if the function is dependent on something else, that something else needs to be mocked so that the tests is always singular and can be run fast. Questions: so am i right to say that the project should have started with unit test with proper mocks using something like rhino mocks. then anything else which requires 3rd party dll, database data access etc to be done via integration testing using selenium? because i have a function which calls a third party dll, i'm not sure whether to write a unit test in nunit to just instantiate the object and pass it some dummy data which breaks the mocking part to test it or just cover that part in my selenium integration testing when i submit my forms and call the dll. and for user acceptance tests, is it safe to say we can just use selenium again? Am i missing something or is there a better way/framework? i'm trying to put in more tests for regression testing, and to ensure that nothing breaks when we put in new features. i also like the idea of TDD because it helps to better define the function, sort of like a meta documentation. thanks!! hope this question isn't too subjective because i need it for my case.

  • php string versus boolean speed test

    - by ae
    I'm looking at trying to optimise a particular function in a php app and foolishly assumed that a boolean lookup in a 'if' statement would be quicker than a string compare. But to check it I put together a short test (see below). To my surprise, the string lookup was quicker. Is there anything wrong with my test (I'm wired on too much coffee so I'm suspicious of my own code)? If not, I would be interested in any comments people have around string versus boolean lookups in php. The result for the first test (boolean lookup) was 0.168 The result for the second test (string lookup) was 0.005 <?php $how_many = 1000000; $counter1 = 0; $counter2 = 0; $abc = array('boolean_lookup'=>TRUE, 'string_lookup'=>'something_else'); $start = microtime(); for($i = 0; $i < $how_many; $i++) { if($abc['boolean_lookup']) { $counter1++; } } echo ($start - microtime()); echo '<hr>'; $start = microtime(); for($i = 0; $i < $how_many; $i++) { if($abc['string_lookup'] == 'something_else') { $counter2++; } } echo ($start - microtime());

  • PHP - Database schema: version control, branching, migrations.

    - by Billiam
    I'm trying to come up with (or find) a reusable system for database schema versioning in php projects. There are a number of Rails-style migration projects available for php. http://code.google.com/p/mysql-php-migrations/ is a good example. It uses timestamps for migration files, which helps with conflicts between branches. General problem with this kind of system: When development branch A is checked out, and you want to check out branch B instead, B may have new migration files. This is fine, migrating to newer content is straight forward. If branch A has newer migration files, you would need to migrate downwards to the nearest shared patch. If branch A and B have significantly different code bases, you may have to migrate down even further. This may mean: Check out B, determine shared patch number, check out A, migrate downwards to this patch. This must be done from A since the actual applied patches are not available in B. Then, checkout branch B, and migrate to newest B patch. Reverse process again when going from B to A. Proposed system: When migrating upwards, instead of just storing the patch version, serialize the whole patch in database for later use, though I'd probably only need the down() method. When changing branches, compare patches that have been run to patches that are available in the destination branch. Determine nearest shared patch (or oldest difference, maybe) between db table of run patches and patches in destination branch by ID or hash. Could also look for new or missing patches that are buried under a number of shared patches between the two branches. Automatically merge down to the nearest shared patch, using the db table stored down() methods, and then merge up to the branche's latest patch. My question is: Is this system too crazy and/or fraught with consequences to bother developing? My experience with database schema versioning is limited to PHP autopatch, which is an up()-only system requiring filenames with sequential IDs.
