  • Help with Magento and related products

    - by Anthony
    I have a customer product page that literally lives beside the catalog/product/view.phtml page. It's basically identical to that page with a few small exceptions. It's basically a 'product of the day' type page so I can't combine it with the regular product page since I have to fetch the data from the DB and perform a load to get the product information $_product = Mage::getModel('catalog/product')->load($row['productid']); To make a long story short, everything works (including all children html blocks) with the singular exception of the related products. After the load I save the product into the registry with Mage::register('product', $_product); and then attempt to load the related products with: echo $this->getLayout()->createBlock('catalog/product_view')->setTemplate('catalog/product/list/related.phtml')->toHtml();` All of which give back the error: Fatal error: Call to a member function getSize() on a non-object in catalog/product/list/related.phtml on line 29`, and line 29 is <?php if($this->getItems()->getSize()): ?>`. Any help getting the relateds to load would be appreicated.

  • For anyone with free time: Trying to learn how to replace PHP with Python, failing terribly.

    - by MALON
    I want give web development using Python a shot, but I'm failing hard. I don't even know if I CAN run Python. The webpage for my web host says it supports all kinds of stuff, including Python. I've never touched anything CGI related and this does not appear to be a noob friendly area. Below is all the information I could think of that might be useful: Shared host: Yes Webhost: dibbsonhosting.com Server OS: linux Python installed: Yes (or so says the webhost) mod_python installed: Don't Know WSGI installed: Don't Know Access to http.conf: No Terminal access: No Cpanel: Yes FTP: Yes Django: downloaded latest stable release, not uploaded anywhere, not sure where to put it. DB: MySQL 5.x I really want to use Python for web development! Thanks!

  • StreamWriter does throw exception underlying connection is broken?

    - by Jane
    I am using StreamWriter instantiated over a Tcpstream like this streamWriter = new StreamWriter(tcpClient.GetStream()); I am confused about the behaviour of following calls with regards to Exceptions. The following two functions are expected to raise IOException , Surprisingly they do not raise the IOException when the server is to which the tcpClient is connected is disconnected and therefore the underlying TCP client connection is broken.. These two lines execute without raising any Exception. Why ? streamWriter.WriteLine(strBuffer); streamWriter.Flush();

  • Get Python 2.7's 'json' to not throw an exception when it encounters random byte strings

    - by Chris Dutrow
    Trying to encode a a dict object into json using Python 2.7's json (ie: import json). The object has some byte strings in it that are "pickled" data using cPickle, so for json's purposes, they are basically random byte strings. I was using django.utils's simplejson and this worked fine. But I recently switched to Python 2.7 on google app engine and they don't seem to have simplejson available anymore. Now that I am using json, it throws an exception when it encounters bytes that aren't part of UTF-8. The error that I'm getting is: UnicodeDecodeError: 'utf8' codec can't decode byte 0x80 in position 0: invalid start byte It would be nice if it printed out a string of the character codes like the debugging might do, ie: \u0002]q\u0000U\u001201. But I really don't much care how it handles this data just as long as it doesn't throw an exception and continues serializing the information that it does recognize. How can I make this happen? Thanks!

  • Workaround for UnsupportedAudioFileException ?

    - by tschan
    I'm in a very early stage of writing a small music/rhythm game in Java (via Slick framework, which in turns uses OpenAL, but that's probably irrelevant here). The game needs to read (and playback) several sound files in WAV format, but some of the files are throwing [javax.sound.sampled.UnsupportedAudioFileException] exceptions. at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1102) at org.newdawn.slick.openal.WaveData.create(WaveData.java:123) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java:713) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java:683) at org.newdawn.slick.Sound.<init>(Sound.java:33) The files can be played back just fine in Winamp or Foobar2000, so this means Java just don't recognize some variants of the file format. What are my options at this point? Note: The files in question are user-supplied, so i cannot just convert them beforehand (using something like audacity). Any conversion steps must be done at runtime.

  • problem loading resource from class library

    - by mishal153
    I have a class library (mylibrary) which has a resource called "close.png". I used redGate reflector to confirm that the resource is actually present in the dll. Now i use mylibrary.dll in a project where i attempt to extract this "close.png" resource like this : BitmapImage crossImage = new BitmapImage(); crossImage.BeginInit(); crossImage.UriSource = new Uri(@"/mylibrary;component/Resources/close.png", UriKind.RelativeOrAbsolute); crossImage.EndInit(); This BitmapImage crossImage is then used like : Button closeButton = new Button() { Content = new System.Windows.Controls.Image() { Source = crossImage }, MaxWidth = 20, MaxHeight = 20 }; On doing this i get no exceptions being thrown but the button shows no image. Also, i do see some exception info if i investigate the button's 'content' in the debugger.

  • Can jQuery's fadeIn work without AJAX?

    - by Thierry Lam
    I'm submitting a form, sometimes I have some messages that I want to show to the user. I want those messages to jQuery fadeIn after they click on the submit button. Is it possible to achieve that if the submission doesn't involve any AJAX? Here's a sample Django/Python code: # View code message = 'feedback to user' # Template <div id="messages">{{ message }}</div> The equivalent PHP code of the above might be: <?php $message = 'feedback to user'; ?> <div id="messages"><?= $message ?></div> I want #messages above to fade in after a POST. How can I achieve that?

The following are the details of the question: A] Platform being used -- google app engine with python, django. B] Tutorial link being used -- http://code.google.com/appengine/articles/djangoforms.html C] Question: In the application i am building, there is a drop down box which allows the user to select their country.

  • Need help on how to setup my packages and projects in eclipse

    - by jax
    I am new to Java and am making a license generator. This is my current setup. com.example.licensegenerator.client (used by the client application) :LicenseLoader (no Main method) :LicenseDownloader (no Main method) com.example.licensegenerator.server.keys (used by the server) :ProductKeyGenerator(Main method) com.example.licensegenerator.server.license (used on the server also) :LicenseGenerator(Main method) com.example.licensegenerator.lib (Shared classes between client and server) :Contants (no main) Now I have a few questions. Is it OK to have multiple Main() methods in a single project? Will I be able to compile them to different .jar files? (In this case I need two different jars for the server) Is there a better way to setup the packages? And a totally unrelated question, with exceptions, is it better to handle them right then and there or throw them and let the main method catch them all (the program cannot recover if an error occurs)

  • NOT LIKE not working on comparison to a column

    - by rodling
    Data is fairly large and takes few minutes to run it every time, so its taking a lot of time debugging this problem. When I run like concat('%',T.item,'%') on smaller data it seems to identify items properly. However, when I run it on the main DB (the code shown), it still shows many(maybe even all) of the exceptions. EDIT: it seems when i add NOT it stops identifying items select distinct T.comment from (select comment, source, item from data, non_informative where ticker != "O" and source != 7 and source != 6) as T where T.comment not like concat('%',T.item,'%') order by T.comment; comment and source are in data, item is in non_informative Some items from T.item: 'Stock Analysis -', '#InsideTrades', 'IIROC Trade' Example comment which should be removed '#InsideTrades #4 | MACNAB CRAIG (Director,Officer,Chief Executive Officer): Filed Form 4 for $NNN (NATIONAL RETA' Can't seem to figure out it why shows all the items

  • In ASP.NET MVC, how does response.redirect work?

    - by Swoop
    I have used response.redirect in classic ASP and ASP.NET webforms. However, with MVC 2.0, I am running into something peculiar. I have a private method in a controller class that is used by multiple controller methods to help load and validate some information. This private method is setup to redirect if a problem is discovered to a generic error message page. The big problem I am noticing is that the calling controller class and page view attempt to complete rendering and loading before the redirect actually takes place. This is annoying in development because the View throws exceptions that I need to ignore before my generic error page finally loads. As mentioned above, I am used to the older model of response.redirect which prevented subsequent code on a page from being executed as the new page would then load. Any help or advice on redirects in MVC would be greatly appreciated.

  • How to make HTML5 speech recognition not ask permission every time

    - by user2081044
    I have created a script that requires my microphone. It uses the HTML5 speech recognition API. Chrome asks permission every time I want to perform a speech recognition test. Javascript (partial) code that I am using: var recognition = new webkitSpeechRecognition(); recognition.continuous = true; recognition.interimResults = true; recognition.onresult = function(event) { console.log(event.results[0][0].transcript); if(event.results[0][0].transcript === 'print') { console.log(''); } }; recognition.start(); I have tried to add it into the list of exceptions in either Chrome and Flash player, but it still asks for permission. Printscreen: That message pops up everytime I click the button. Is there any way to disable Chrome for asking permission?

  • Current state of Erlang web development? Frameworks, Template languages

    - by pommonico
    Django is to Python as Rails is to Ruby. What is the current front-runner for Erlang? Recent Erlang web activity has resulted in many new frameworks but they are all still moving targets. ErlyWeb is very far along but now seems to be dead. If you were to invest significant capital into a new web product (i.e. not a hobby, you use your own money and you use other's investment in you with expectation of payback), would you choose Erlang as a web platform? If so, what framework and technologies would you choose?

  • errorPage directive works, but error-page in web.xml doesn't?

    - by danb
    I get jsp exceptions causing a forward to my error page when I put this at the top of my JSPs... <%@ page errorPage="/error.page" %> but when I try to do it globally with web.xml like so: <error-page> <exception-type>java.lang.Throwable</exception-type> <location>/error.page</location> </error-page> I just get a blank page... I've also tried putting /error.jsp in the location element.. but no love with that either.. I am triggering an exception with a jsp that just contains this: <%if(true)throw new RuntimeException("test exception");%> I do see the exception in the console from tomcat but I just can't get that error page to show without a directive on every jsp... am I missing something simple here?

  • The D Programming Language for Game Development

    - by n2liquid
    Hi all, Recently I've been bothered because I reached a point in which C++ (even 0x) felt very limited, so I started looking for alternatives. Forget Java, C#, Python or Ruby. I still like the low-level nature of C++ and I'm not fond of virtual machines. Further, I'm a game engine developer, so I have to develop core routines which must be really fast, and lately I've been hungry for code expressiveness. C++ is an almost-there language for me, but there are many exceptions on how to use templates, and GCC isn't optimizing stuff as well as I'd hoped it would. So I'm considering to start learning D. Do you think it will suffice my needs as a game developer? I'm weary because I've never heard of D being used for that. Thanks!
