• Get products to display on custom Magento page

  - by Eric

  How can you get products to display on a custom Magento page? Naturally, this is not an uncommon question but nothing that I've seen has solved it for me. The common response is to put the following code in through the CMS editor: {{block type="catalog/product_list" name="home.catalog.product.list" alias="products_homepage” template=”catalog/product/list.phtml”}} Which just displays the message "There are no products matching the selection." on my page. Other websites advise reindexing the data through the Magento admin controls, clearing the Magento cache, and making sure products are set to a store, none of which helped in my case. Anyone have any ideas?

• Django i18n: makemessages only on site level possible?

  - by AndiDog

  I have several strings in my site that don't belong to any app, for example {% block title %}{% trans "Login" %}{% endblock %} or a modified authentication form used to set the locale cookie class AuthenticationFormWithLocaleOption(AuthenticationForm): locale = forms.ChoiceField(choices = settings.LANGUAGES, required = False, initial = preselectedLocale, label = _("Locale/language")) Now when I execute django-admin.py makemessages --all -e .html,.template in the site directory, it extracts the strings from all Python, .html and .template files, including those in my apps. That is because I develop my apps inside that directory: Directory structure: sitename myapp1 myapp2 Is there any way to extract all strings that are not in my apps? The only solution I found is to move the app directories outside the site directory structure, but I'm using bzr-externals (similar to git submodules or svn externals) so that doesn't make sense in my case. Moving stuff that needs translation into a new app is also possible but I don't know if that is the only reasonable solution.

• is it better to use a "natural" language to write codes ?

  - by M.H

  I recently saw a programming language called supernova and they said in the web page : The Supernova Programming language is a modern scripting language and the First one presents the concept of programming with direct Fiction Description using Clear subset of pure Human Language. and you can write codes like : i want window and the window title is Hello World. i want button and button caption is Close. and button name is btn1. btn1 mouse click. instructions are you close window end of instructions my question is not about the language itself but it is that are we need such languages and did they make writing codes more easier or not ?

• How do I make the footer stretch vertically downward align to footer.

  - by text

  I am new to web design using tableless and I'm having problem positioning some elements on my page.. Here's the sample html: http://christianruado.comuf.com/sample.html As you can see from the screen shots I want my right div to be vertically stretched down to the same level of my footer and position my bottom element to the lowest part of the right container. #right { float:right; width: 19%; background:#FF3300; margin-left:2px; height: 100%; } #right .bottom { bottom:0; display:block; background-color:#FFCCFF; height:30px; }

• 'Static/Constant' business ojects

  - by UpTheCreek

  I don't quite know how to ask this question, so I'll phase it as an example: Imagine in an application you have a Country object. There are two properties of this object: Name, and a 'Bordering Countries' collection. More properties might be added later, but it will be the kind of information that would change very rarely (e.g. changes of country names/borders) Lets say this application needs to know about all of the countries in the world. Where would you store these object's state? How would you new them up? It seems silly to store all this state in the DB, since it won't change very often. One option might be to have an abstract 'country' base object, and have a class for each country inheriting from this with the details of each country. But this doesn't seem quite right to me. What is the proper way of dealing with these kinds of objects?

• What should i do to practise?

  - by simion

  Hi guys I start a year long industrial placement in september where i will be coding in java predominantly. I am going to use the summer to brush up on my java as in year one of the degree java was the main language taught for OOP modules. However this year i have had no java exposure except for an algorithms module, which was one of eight, so as you can see i am probably getting really rusty!. What i wanted to know is, how does the "real world" java programming differ from university coding and what do you suggest i brush up on that would be different to my normal workings. As a start i definatley need to get familiar with a professional IDE like netbeans, opoosed to havign used BlueJ throughout but more specifically what coding practises should i get more familiar with I appreciate they wont expect me to be a qualified full developer and will give me time, but i would like to hit the ground running as it were, with me having full hopes to secure a perminant position after i finish my degree. Thanks for reading

• CSS Sliding Underline does not work in Safari?

  - by ghilton

  I have created a navigation menu which has a 'sliding underline' effect for each hyperlink. JS Fiddle: http://jsfiddle.net/ZZuQR/12/ RELEVANT CODE: /* sliding underline */ nav li a:after { content: " "; display:block; margin: 5px 0px 0px 0px; border-bottom: 3px solid transparent; width: 0px; transition: 0.5s ease; } nav li a:hover:after { border-bottom: 3px solid #0076a3; width:50px; } This solution works in Chrome but not in Safari. Does anyone know why this might be?

• Is it better to adopt the same technologies used at work to be effective on your home projects ?

  - by systempuntoout

  Is it better to start developing an home project using the same technologies used at work to be more productive and effective? I'm not talking about a simple hello world web page but an home project with all bells and whistles that one day, maybe, you could sell on internet. This dilemma is often subject of flames between me and a friend. He thinks that if you want to make a great home-made project you need to use the same technologies used daily at work staying in the same scope too; for example, a c++ computer game programmer should develope an home-made c++ game. I'm pretty sure that developing using the same technologies used at work can be more productive at beginning, but surely less exciting and stimulating of working with other languages\ides\libraries out of your daily job. What's your opinion about that?

• How to determine the inner context node within an XSLT select

  - by Marcus Rickert

  Hi there! I'm trying to determine a subset of nodes stored in the variable objs by using a user defined function cube:is_active: <xsl:variable name="active_cubes" select="$objs[cube:is_active(XXX) = 'TRUE']"/ Since the function does not allow a local context I'm required to pass it as a parameter (denoted by XXX). However, the usual suspects "." or "current()" do not work since they refer to context node of the surrounding block and NOT to the current element of objs which is evaluated. The only solution so far which DOES work is: XXX=SOME_CHILD_TAG/.. But this is really ugly since it depends on the existence of the child tag for the parent node to work correctly. Is there any other way? Thanks!

• How to get rid of this sliver of white between DIVs?

  - by George Edison

  I am currently having trouble getting rid of a sliver of white... Here is an example page: http://m.stackoverflow.quickmediasolutions.com/view_question.php?id=97969&site=serverfault As you can see, the answers have a sliver of white stuffed between the top of the 'button' and the content. Here is some relevant code: <!-- this is the top of the 'button' --> <div class='top'></div> <!-- right here is where the space is --> <div class='content'></div> .top { height: 5px; } .content { display: block; padding-left: 10px; }

• Porting library from Java to Python

  - by Mike Griffith

  I'm about to port a smallish library from Java to Python and wanted some advice (smallish ~ a few thousand lines of code). I've studied the Java code a little, and noticed some design patterns that are common in both languages. However, there were definitely some Java-only idioms (singletons, etc) present that are generally not-well-received in Python-world. I know at least one tool (j2py) exists that will turn a .java file into a .py file by walking the AST. Some initial experimentation yielded less than favorable results. Should I even be considering using an automated tool to generate some code, or are the languages different enough that any tool would create enough re-work to have justified writing from scratch? If tools aren't the devil, are there any besides j2py that can at least handle same-project import management? I don't expect any tool to match 3rd party libraries from one language to a substitute in another.

• How do I attach an event handler to the document or window in GWT?

  - by Raph Levien

  In a GWT app centered around a canvas, I'm having trouble keeping focus directed in the right place - particularly for keyboard shortcuts. For now, I've wrapped the canvas in a FocusPanel, but that causes the canvas to not respond to the RequiresResize protocol, because FocusPanel does not plumb that. A second (related, I think) problem is that the FocusPanel is not getting Ctrl-A keypress events at all (tested on Mac Chrome). I can get Ctrl-Z and other keys (such as arrows) just fine. In a pure JavaScript world, I think the best answer to this would be to attach mouse and key handlers to the document or window object (I'm not positive which is better). However, I don't see an obvious way to do this in GWT - in particular, the Document and Window classes lack methods for attaching these kind of event handlers? Anyone know how to do it, or, perhaps, to solve the more general problem of keeping focus on an appropriate widget able to handle keyboard shortcuts?

• Adding new column in Sales Order View Items in Magento Admin

  - by fdierre

  In the admin interface of Magento I need to modify the tables in the Sales / Order / View order so that it shows, besides the products name, their manufacturer as well. I'm trying to look for the file to modify to make that happen. I thought I would find a section with all the columns that are displayed in app/code/core/Mage/Sales/Block/Order/Item/Renderer/Default.php but by inspecting it there seem to be no reference to the columns/product attributes. I also tried to modify app/design/adminhtml/default/default/template/sales/order/view/items/renderer/default.phtml by changing <?php echo $this->getColumnHtml($_item, 'name') ?> into <?php echo $this->getColumnHtml($_item, 'manufacturer') ?> but it changed nothing, so I suppose that file is not involved... Can anybody please point me to the right file to modify? Thank you!

• How to add a Tooltip to a "td" with jquery?

  - by Scott

  I need to add a tooltip/alt to a "td" element inside of my tables with jquery. Can someone help me out? I tried: var tTip ="Hello world"; $(this).attr("onmouseover", tip(tTip)); where I have verified that I am using the "td" as "this". Edit:I am able to capture the "td" element through using the "alert" command and it worked. So for some reason the "tip" function doesn't work. Anyone know why this would be?

• What is the best way to secure a shared git repo for a small distributed team ?

  - by ashy_32bit

  We have a Scala project and we decided to use git. The problem is we are a very small distributed team and we want nobody outside of the team to have even the read only access to our git server (which has a valid IP and is world-accessible in the IP level). I have heard the git-daemon has no authentication mechanism by itself and you should somehow integrate it with ssh or something. What is the best (and easiest) way to make the git server respond only to authorized users ? Or perhaps git-daemon is not for this task ? I may add that I am looking for a simple and straightforward approach. I don't want to compete with github ;-)

• Call javascript function from Java (Groovy) class

  - by ashkanr

  Hi, I have a javascript function (very big one!) that I need its functionality in a Java (Groovy) class. It is a simple calendar converter. I can rewrite it in groovy but just want to know if it is possible to call javascript function from a java (groovy) method? I guess functional testing libraries like selenium and Canoo should have something like this, am I right? PS: I don't want to wake up a real-world browser in order to use its JS runtime env. Thanks,

• How to use JNI, but only when available for current platform?

  - by Mecki

  What is the common way (or best practice) to optionally use JNI? E.g. I have a Java class and this class is 100% pure Java, so it can run on all platforms. However, on some platforms I'd like to speed up some heavy calculations using JNI - which works fine. Unfortunately I cannot support any existing Java platform in the world. So I guess it is fine to initially only support the big three: Linux, Windows, Mac OS X. So what I'd like to do is to use JNI on those three platforms and use the 100% pure Java version on all other platforms. Now I can think of various ways how to do that (loading class dynamically for example and either loading the JNI class or the pure Java one), but thinking that this is a common issue that thousands of projects had to solve in the past for sure, I'm really surprised to not find any documentation or references to the question how to solve this most elegantly or effectively.

• Database Design Question: GUID + Natural Numbers

  - by Alan

  For a database I'm building, I've decided to use natural numbers as the primary key. I'm aware of the advantages that GUID's allow, but looking at the data, the bulk of row's data were GUID keys. I want to generate XML records from the database data, and one problem with natural numbers is that I don't want to expose my database key's to the outside world, and allow users to guess "keys." I believe GUID's solve this problem. So, I think the solution is to generate a sparse, unique iD derived from the natural ID (hopefully it would be 2-way), or just add an extra column in the database and store a guid (or some other multibyte id) The derived value is nicer because there is no storage penalty, but it would be easier to reverse and guess compared to a GUID. I'm (buy) curious as to what others on SO have done, and what insights they have.

• Does ASP.NET Make Request Scheduling Decisions Based Upon SessionID?

  - by Mike Murphy

  I know that a properly implemented SessionStateStoreProvider maintains an exclusive lock on session data for the duration of a request. However, considering that multiple requests could arrive simultaneously (e.g. via IFRAMEs) all but one would be able to make forward progress. All the other requests would block for a bit and reduce the number of worker threads available during that time. It seems if ASP.NET "peeked" at the session IDs on the requests early on, it could avoid running requests simultaneously that were on the same session. This would improve throughput under load for pages that didn't want to give up using IFRAMEs. This seems plausible enough that it might be true.

• How do I resolve this scope issue in VB .NET?

  - by froadie

  I have a code structure something like this: For row = 1 To numRows Dim arrayIndex As Integer = 0 For column As Integer = bucketStartColumn To bucketEndColumn ' whatever code arrayIndex = arrayIndex + 1 Next Next Dim arrayIndex As Integer = 0 For column As Integer = bucketStartColumn To bucketEndColumn ' whatever code arrayIndex = arrayIndex + 1 Next Not exactly the code, so I don't really need suggestions about refactoring, but my problem is this - with this code I get a compiler error for the first Dim arrayIndex As Integer = 0 - "Variable 'arrayIndex' hides a variable in an enclosing block." As far as I can tell, arrayIndex is local to the first for loop and shouldn't exist by the time we reach the second loop. If I try to change the second declaration of arrayIndex to arrayIndex = 0, I get the error "Name 'arrayIndex' is not declared", as I expected. So is it visible, or not? Does this have something to do with the Dim keyword? Any suggestions of how to get around this, other than naming the second index variable something else?

• How to use #ifdef entities as part of functions in header files

  - by Crazyjavahacking

  I would like to ask if it is possible to use the entities defined in #ifdef block in header files. To be clear, I have following code: #ifdef #include <winsock2.h> #define SOCKET_HANDLE SOCKET #define CONNECTION_HANDLE SOCKET #endif SOCKET_HANDLE createServerSocket(const char* hostAddress, short port); I am Java developer and this seems completely fine for me. However compiler has a problem with this. Can you explain why is that code a problem? Also how can I force to compile it. (The idea is to have generic interface and conditional compilation to determine real types according to running platform at compile time.) Thanks
