  • Setting up multiple cores for apache solr for Ubuntu 12.04 and Drupal 7

    - by chrisjlee
    I'm setting up solr locally for my development purposes and integration with Drupal 7. I'm not very familiar with tomcat. My background has primarily been LAMP setups. So I went and installed the package provided by ubuntu for apache solr following this guide. sudo apt-get install tomcat6 tomcat6-admin tomcat6-common tomcat6-user tomcat6-docs tomcat6-examples sudo apt-get install solr-tomcat I've got that working. The apt-get package manager does a great job and allows me to setup solr but with one core. What steps need to be taken to enable multi core setup for apache solr? And below is my solr.xml file: sudo nano /var/lib/tomcat6/conf/Catalina/localhost/solr.xml <!-- Context configuration file for the Solr Web App --> <Context path="/solr" docBase="/usr/share/solr" debug="0" privileged="true" allowLinking="true" crossContext="true"> <!-- make symlinks work in Tomcat --> <Resources className="org.apache.naming.resources.FileDirContext" allowLinking="true" /> <Environment name="solr/home" type="java.lang.String" value="/usr/share/solr" override="true" /> </Context>

  • Can I have a computer with 2 physical HDs, & Dual boot option, one for Windows & one for Ubuntu

    - by Frank
    When my HD failed in my old computer with a dual core, I immediately went out and bought a new 6 core PC because I needed it for business and had to have an immediate solution. The old computer was otherwise a good computer. I don't want to spend a $100+ for a new operating system for the old computer because the Windows 7 Professional opperating system for the new computer will only allow one install. So, I decided to look and see if there were any free operating systems and found Ubuntu. I downloaded it and burned a live CD and would like to try it on the old computer. I found a 200 GB HD I can buy for $30 and the seller will format it any way I want. There are also other HDs available at a similar price. What I was thinking I would like to do is buy 2 HDs. Then I can have one formatted for Ubuntu 12.04 and install Windows XP Pro SP1 on the other HD for which I have the original installation CD. Then I would like to have a dual boot option so that when I power up the computer, I can choose whether to use Windows XP or Ubuntu. Is this possible? If so, how would I do it, that is, arrange it so a dual boot option presents itself on power up.

  • How to write code that communicates with an accelerator in the real address space (real mode)?

    - by ysap
    This is a preliminary question for the issue, where I was asked to program a host-accelerator program on an embedded system we are building. The system is comprised of (among the standard peripherals) an ARM core and an accelerator processor. Both processors access the system bus via their bus interfaces, and share the same 32-bit global physical memory space. Both share access to the system's DRAM through the system bus. (The computer concept is similar to Beagleboard/raspberry Pie, but with a specialized accelerator added) The accelerator has its own internal memory (SRAM) which is exposed to the system and occupies a portion of the global address space (as opposed to how a graphics card would talk to teh CPU via a "small" aperture in the system memory space). On the ARM core (the host) we plan on running Ubuntu 12.04. The mode of operation of communicating between the processors should be that the host issues memory transactions on the system bus that are targeted at the accelerator internal memory. As far as my understanding goes, if I write a program for the host that simply writes to the physical address of the accelerator, most chances are that the program will crash due to a segmentation violation. So, I assume that I need some way of communicating with the device in real mode. What is the easiest way to achieve this mode of operation?

  • I have an "amoeba" game mechanic. Any idea on how to implement it?

    - by Jason
    Outside of a tetris clone, a crappy 2D top-down shooter, and some messing around with stuff like Unity and Flixel, I realize that I have yet to complete a single, polished, bells-and-whistles game. I want to change this, and I have an idea for my next project. The idea is that you're an amoeba. Amoebas have these eye-like cores (or something like that, I don't know biology), and you have two of 'em. You control one with WASD and the other with IJKL. There has to be a constant radius of stuff around each of the cores: And the area of the amoeba has to stay constant. So if you move a core in one direction, you increase the amoeba's area, but that increase is compensated by a decrease somewhere else: Aaaaaand I'd like to implement a vagination mechanic. You absorb things by engulfing them, like a boss. Maybe even an extra core, or a needle that pops you and causes all your inner stuff to start gushing out: But here's the problem: I don't know how to make this. However, I would like some ideas on how to implement it. Should I explore physics libraries like Box2D? Or maybe something involving fluid physics? Any help would be much appreciated. P.S. Feel free to steal this idea. I have plenty of ideas. If you do, please tell me how you made it so I can try it myself.

  • Best practices in versioning

    - by Gerenuk
    I develop some scripts for data analysis in a small team. For the moment we use SVN, but not in a very structured way. We haven't even looked how to use branches even though we need this functionality. What do you suggest as the best practice to setup the following system: two code bases (core and plugins) versions can be incompatible to previous scripts sometimes individual features are being developed and not yet finished, while other fixes have to be done urgently to the code In the end we don't deliver the code as a package, but rather place the Python scripts in some directory (with version names?). Some other python script which serves as a configuration choses the desired version, sets the path to these libraries and then starts to import the modules. I saw stable releases to be named "trunk" so I did the same. However, no version numbers yet. Core and plugins are different repositories, however we have to match versions for compatibility. Can you suggest some best practices or reference to ease development and reduce chaos? :) Some suggested GIT. I haven't heard about it, but I'm free to change.

  • Is there such thing like a "refactoring/maintainability group" role in software companies?

    - by dukeofgaming
    So, I work in a company that does embedded software development, other groups focus in the core development of different products' software and my department (which is in another geographical location) which is located at the factory has to deal with software development as well, but across all products, so that we can also fix things quicker when the lines go down due to software problems with the product. In other words, we are generalists while other groups specialize on each product. Thing is, it is kind of hard to get involved in core development when you are distributed geographically (well, I know it really isn't that hard, but there might be unintended cultural/political barriers when it comes to the discipline of collaborating remotely). So I figured that, since we are currently just putting fires out and somewhat being idle/sub-utilized (even though we are a new department, or maybe that is the reason), I thought that a good role for us could be detecting areas of opportunity of refactoring and rearchitecting code and all other implementations that might have to do with stewarding maintainability and modularity. Other groups aren't focused on this because they don't have the time and they have aggressive deadlines, which damage the quality of the code (eternal story of software projects) The thing is that I want my group/department to be recognized by management and other groups with this role officially, and I'm having trouble to come up with a good definition/identity of our group for this matter. So my question is: is this role something that already exists?, or am I the first one to make something like this up?

  • 13.04 Temp Save, rt3290, Kernel downgrade

    - by user170534
    It's kind of a multiplying but I didn't wanted to open more than one topics. I'd have a fresh install of Ubuntu with tlp configured and using acpi_call to keep 7670M turned off. I was a short time arch user and with openbox and firefox it was about 60 to 70 degrees; wanted to turn to a stable release just for this reason. acpitz-virtual-0 Adapter: Virtual device temp1: +50.0°C radeon-pci-0100 Adapter: PCI adapter temp1: -128.0°C coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +56.0°C (high = +87.0°C, crit = +105.0°C) Core 0: +54.0°C (high = +87.0°C, crit = +105.0°C) Core 1: +55.0°C (high = +87.0°C, crit = +105.0°C) The temperature is not seriously high yet can be lower. Another issue is my wifi card, rt3290: The rt2800pci module is fine and all that but the download performance is pretty bad alongside of annoying signal range and the prop. driver gives a conf error about some specific rt2860 code and integrales in pci_dev file. If I blank off the error making variables, module loads but the driver is unused. Since the driver is old, I was thinking of downgrading the kernel of raring to 3.7 or may be 3.6. Should &-or can I?

  • WIFI/LAN not working after Installing Ubuntu 13.10

    - by user183025
    I can't connect to my WIFI after installing Ubuntu 13.10. I tried re-installing it three times (thinking that I did something wrong during the installation) but I still can't connect to my WIFI. It just gives me the message that I'm offline and that I can't connect to my WIFI. I also tried connecting to the internet using LAN cable but with the same results. I tried google but it seems that there's no solution to this yet.... Anybody knows how to solve this? Thanks!

  • Context switches much slower in new linux kernels

    - by Michael Goldshteyn
    We are looking to upgrade the OS on our servers from Ubuntu 10.04 LTS to Ubuntu 12.04 LTS. Unfortunately, it seems that the latency to run a thread that has become runnable has significantly increased from the 2.6 kernel to the 3.2 kernel. In fact the latency numbers we are getting are hard to believe. Let me be more specific about the test. We have a program that has two threads. The first thread gets the current time (in ticks using RDTSC) and then signals a condition variable once a second. The second thread waits on the condition variable and wakes up when it is signaled. It then gets the current time (in ticks using RDTSC). The difference between the time in the second thread and the time in the first thread is computed and displayed on the console. After this the second thread waits on the condition variable once more. So, we get a thread to thread signaling latency measurement once a second as a result. In linux 2.6.32, this latency is somewhere on the order of 2.8-3.5 us, which is reasonable. In linux 3.2.0, this latency is somewhere on the order of 40-100 us. I have excluded any differences in hardware between the two host hosts. They run on identical hardware (dual socket X5687 {Westmere-EP} processors running at 3.6 GHz with hyperthreading, speedstep and all C states turned off). We are changing the affinity to run both threads on physical cores of the same socket (i.e., the first thread is run on Core 0 and the second thread is run on Core 1), so there is no bouncing of threads on cores or bouncing/communication between sockets. The only difference between the two hosts is that one is running Ubuntu 10.04 LTS with kernel 2.6.32-28 (the fast context switch box) and the other is running the latest Ubuntu 12.04 LTS with kernel 3.2.0-23 (the slow context switch box). Have there been any changes in the kernel that could account for this ridiculous slow down in how long it takes for a thread to be scheduled to run?

  • How can I speed up boot on one of my machines?

    - by Korneel Bouman
    I have a Gateway all in one machine (2 gig Intel Core 2 Duo T7250 dual core processor, 2 gig RAM - full specs) on which I installed 10.10. Once it has booted it's fine, but it takes forever to boot. This is what happens: 1. Boot starts with cursor flashing for about 10-15 seconds 2. Cursor disappears for 1.5 - 2 minutes 3. Cursor reappears, blinks a few seconds more, boot finishes in another 10 seconds 4. Login screen I have another machine with marginal better specs that boots up in no time (basically the above minus the two minute delay). Things I've done: enabled verbose mode for grub nothing is showing until after 2 minute pause. checked syslog last message before pause is a message from alsa saying the process is already running (or something similar... going from memory here...) It could be something sound related as the built in speakers are not working (sound card is recognized though and headphones work). Anyway, it's not the end of the world, but it's annoying and I'd like to know what's going on... Many thanks, and let me know if more info is needed.

  • Best way to generate pieces in match-3 games, and then tracking them?

    - by JonLim
    I've been working on a match-3 style game in Actionscript using Flixel, and so far, I've been able to build the core mechanics of the game, including board generation, piece generation, piece swapping and movement, and checking algorithms. However, I am now running into issues with clearing out pieces and letting the above pieces fall down and generating new pieces. The reason I'm running into these issues is that when all of the pieces are generated, the pertinent values (position, sprite ID, and sprite object) are pushed into an array that helps me track everything, all the time. When pieces are moved, I swap the values of the corresponding arrays and life goes on. And that array is the core of my problem: if a row in the middle of the board clears out, ideally, all of the pieces above the cleared pieces should fall down to take their place and new pieces are generated at the top and also fall into place. Except if I try to do that now, all the pieces can fall down, but then I'd have to bump all of their values into the right arrays (oh god my head) and then generate new pieces and fit THOSE into the correct place in the array. Am I overthinking this? Or is there a far better way to track these pieces? Thanks guys!

  • JMS messaging implementation

    - by Gandalf StormCrow
    I've been struggling with this "simple" task for more expirienced people, I'm stuck for 2 days now need help. I've changed things arround like zillion times now, finally I stumbled upon this spring JMS tutorial. What I want to do, Send a message and receive it. I've been also reading this book chapter 8 on messaging. It really nicely explains 2 type of messaging and there is nice example for publish-and-subscribe type but now example for point-to-point messaging( this is the one I need). I'm able to send message to the queue on my own, but don't have a clue how to receive thats why I tried with this spring tutorial here is what I've got so far : SENDER : package quartz.spring.com.example; import java.util.HashMap; import java.util.Map; import javax.jms.ConnectionFactory; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.Queue; import javax.jms.Session; import org.springframework.jms.core.MessageCreator; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.JmsTemplate102; import org.springframework.jms.core.MessagePostProcessor; public class JmsQueueSender { private JmsTemplate jmsTemplate; private Queue queue; public void setConnectionFactory(ConnectionFactory cf) { this.jmsTemplate = new JmsTemplate102(cf, false); } public void setQueue(Queue queue) { this.queue = queue; } public void simpleSend() { this.jmsTemplate.send(this.queue, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session.createTextMessage("hello queue world"); } }); } public void sendWithConversion() { Map map = new HashMap(); map.put("Name", "Mark"); map.put("Age", new Integer(47)); jmsTemplate.convertAndSend("testQueue", map, new MessagePostProcessor() { public Message postProcessMessage(Message message) throws JMSException { message.setIntProperty("AccountID", 1234); message.setJMSCorrelationID("123-00001"); return message; } }); } } RECEIVER : package quartz.spring.com.example; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; public class ExampleListener implements MessageListener { public void onMessage(Message message) { if (message instanceof TextMessage) { try { System.out.println(((TextMessage) message).getText()); } catch (JMSException ex) { throw new RuntimeException(ex); } } else { throw new IllegalArgumentException("Message must be of type TextMessage"); } } } applicationcontext.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.0.xsd"> <bean id="sender" class="quartz.spring.com.example.JmsQueueSender" init-method="sendWithConversion" /> <bean id="receiver" class="quartz.spring.com.example.ExampleListener" init-method="onMessage" /> </beans> Didn't really know that learning curve for this is so long, I mean the idea is very simple: Send message to the destination queue Receive message from the destination queue To receive messages, you do the following(so does book say): 1 Locate a ConnectionFactory, typically using JNDI. 2 Use the ConnectionFactory to create a Connection. 3 Use the Connection to create a Session. 4 Locate a Destination, typically using JNDI. 5 Use the Session to create a MessageConsumer for that Destination. Once you’ve done this, methods on the MessageConsumer enable you to either query the Destination for messages or to register for message notification. Can somebody please direct me towards right direction, is there a tutorial which explains in details how to receive message from the queue?I have the working send message code, didn't post it here because this post is too long as it is.

  • WCF Service, Java JApplet client, transport error 405

    - by Juan Zamudio
    Hi all, I'm having a problem with a WCF Service and Java Client, I will try to give as much information as i can, thanks for your time. The Endpoint of the server is BasicHttpBinding, I tried hosting the server as a Windows Service and in IIS but nothing changed. The weird thing is that the Client works great if I use a simple class, in the moment I switch the class to an JApplet I get the problem mentioned. I'm using Eclipse as an IDE, I tried Axis and Metro to generate the stub with the same bad results. Here is an example of the Java class where everything is working public class TestSoaMetro { public String TestMethod(){ String result=null; IDigitalSignatureService aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); try { result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } Here is the example of the JApplet where I get the error: public class TestSoaMetroApplet extends JApplet { public void init() { Container content = getContentPane(); content.setBackground(Color.white); content.setLayout(new FlowLayout()); String result= this.TestMethod(); JLabel label = new JLabel(result); content.add(label); } public String TestMethod(){ String result=null; IDigitalSignatureService aa = null; try { aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } In the moment the Applet loads I get the error, is the exact same call so I don't understand why I get the exception using the Applet. I Also tried to call this from a Silverlight client and I was getting a security exception, this is where I found out about clientaccesspolicy.xml and crossdomain.xml, I added clientaccesspolicy.xml to the service and the Silverlight Client works great, so I decided to try crossdomain.xml and nothing, the Applet still does not work. I will put the stack trace at the end, thanks all for your time.

  • Thread Synchronisation 101

    - by taspeotis
    Previously I've written some very simple multithreaded code, and I've always been aware that at any time there could be a context switch right in the middle of what I'm doing, so I've always guarded access the shared variables through a CCriticalSection class that enters the critical section on construction and leaves it on destruction. I know this is fairly aggressive and I enter and leave critical sections quite frequently and sometimes egregiously (e.g. at the start of a function when I could put the CCriticalSection inside a tighter code block) but my code doesn't crash and it runs fast enough. At work my multithreaded code needs to be a tighter, only locking/synchronising at the lowest level needed. At work I was trying to debug some multithreaded code, and I came across this: EnterCriticalSection(&m_Crit4); m_bSomeVariable = true; LeaveCriticalSection(&m_Crit4); Now, m_bSomeVariable is a Win32 BOOL (not volatile), which as far as I know is defined to be an int, and on x86 reading and writing these values is a single instruction, and since context switches occur on an instruction boundary then there's no need for synchronising this operation with a critical section. I did some more research online to see whether this operation did not need synchronisation, and I came up with two scenarios it did: The CPU implements out of order execution or the second thread is running on a different core and the updated value is not written into RAM for the other core to see; and The int is not 4-byte aligned. I believe number 1 can be solved using the "volatile" keyword. In VS2005 and later the C++ compiler surrounds access to this variable using memory barriers, ensuring that the variable is always completely written/read to the main system memory before using it. Number 2 I cannot verify, I don't know why the byte alignment would make a difference. I don't know the x86 instruction set, but does mov need to be given a 4-byte aligned address? If not do you need to use a combination of instructions? That would introduce the problem. So... QUESTION 1: Does using the "volatile" keyword (implicity using memory barriers and hinting to the compiler not to optimise this code) absolve a programmer from the need to synchronise a 4-byte/8-byte on x86/x64 variable between read/write operations? QUESTION 2: Is there the explicit requirement that the variable be 4-byte/8-byte aligned? I did some more digging into our code and the variables defined in the class: class CExample { private: CRITICAL_SECTION m_Crit1; // Protects variable a CRITICAL_SECTION m_Crit2; // Protects variable b CRITICAL_SECTION m_Crit3; // Protects variable c CRITICAL_SECTION m_Crit4; // Protects variable d // ... }; Now, to me this seems excessive. I thought critical sections synchronised threads between a process, so if you've got one you can enter it and no other thread in that process can execute. There is no need for a critical section for each variable you want to protect, if you're in a critical section then nothing else can interrupt you. I think the only thing that can change the variables from outside a critical section is if the process shares a memory page with another process (can you do that?) and the other process starts to change the values. Mutexes would also help here, named mutexes are shared across processes, or only processes of the same name? QUESTION 3: Is my analysis of critical sections correct, and should this code be rewritten to use mutexes? I have had a look at other synchronisation objects (semaphores and spinlocks), are they better suited here? QUESTION 4: Where are critical sections/mutexes/semaphores/spinlocks best suited? That is, which synchronisation problem should they be applied to. Is there a vast performance penalty for choosing one over the other? And while we're on it, I read that spinlocks should not be used in a single-core multithreaded environment, only a multi-core multithreaded environment. So, QUESTION 5: Is this wrong, or if not, why is it right? Thanks in advance for any responses :)

  • Tomcat/Hibernate Problem "SEVERE: Error listenerStart"

    - by JSteve
    I downloaded working example of hibernate (with maven) and installed it on my tomcat, it worked. Then I created a new web project in MyEclipse, added hibernate support and moved all source files (no jar) to this new project and fixed package/paths wherever was necessary. My servlets are responding correctly but when I add "Listener" in web.xml, tomcat returns error "Error ListenerStart" on startup and my application doesn't start. I've carefully checked all packages, paths and classes, they look good. Error message is also not telling anything more except these two words Here is complete tomcat startup log: 17-Jun-2010 12:13:37 PM org.apache.coyote.http11.Http11Protocol init INFO: Initializing Coyote HTTP/1.1 on http-8810 17-Jun-2010 12:13:37 PM org.apache.catalina.startup.Catalina load INFO: Initialization processed in 293 ms 17-Jun-2010 12:13:37 PM org.apache.catalina.core.StandardService start INFO: Starting service Catalina 17-Jun-2010 12:13:37 PM org.apache.catalina.core.StandardEngine start INFO: Starting Servlet Engine: Apache Tomcat/6.0.20 17-Jun-2010 12:13:37 PM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart 17-Jun-2010 12:13:37 PM org.apache.catalina.core.StandardContext start SEVERE: Context [/addressbook] startup failed due to previous errors 17-Jun-2010 12:13:37 PM org.apache.coyote.http11.Http11Protocol start INFO: Starting Coyote HTTP/1.1 on http-8810 17-Jun-2010 12:13:37 PM org.apache.jk.common.ChannelSocket init INFO: JK: ajp13 listening on /0.0.0.0:8009 17-Jun-2010 12:13:37 PM org.apache.jk.server.JkMain start INFO: Jk running ID=0 time=0/22 config=null 17-Jun-2010 12:13:37 PM org.apache.catalina.startup.Catalina start INFO: Server startup in 446 ms My web.xml is: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <listener> <listener-class>addressbook.util.SessionFactoryInitializer</listener-class> </listener> <filter> <filter-name>Session Interceptor</filter-name> <filter-class>addressbook.util.SessionInterceptor</filter-class> </filter> <filter-mapping> <filter-name>Session Interceptor</filter-name> <servlet-name>Country Manager</servlet-name> </filter-mapping> <servlet> <servlet-name>Country Manager</servlet-name> <servlet-class>addressbook.managers.CountryManagerServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>Country Manager</servlet-name> <url-pattern>/countrymanager</url-pattern> </servlet-mapping> </web-app> Can somebody either help me figure out what I am doing wrong? or point to some resource where I may get some precise solution of my problem?

  • Magento Admin Custom Sales Report

    - by Ela
    Hi, I have to develop a module to export collection of product,order,customer combined attributes. So i thought rather than modifying the core sales report for this purpose better to do a custom functionality. These are the steps that i did but i am not able to produce it. Used magento 1.4.1 version for this. Under /var/www/magento141/app/code/core/Mage/Reports/etc/adminhtml.xml Added these lines for menus. <ereaders translate="title" module="reports"> <title>EReader Sales Report</title> <children> <ereaders translate="title" module="reports"> <title>Sales Report</title> <action>adminhtml/report_sales/ereaders</action> </ereaders> </children> </ereaders> Under /var/www/magento141/app/design/adminhtml/default/default/layout/sales.xml Added these lines for filter condition. <adminhtml_report_sales_ereaders> <update handle="report_sales"/> <reference name="content"> <block type="adminhtml/report_sales_sales" template="report/grid/container.phtml" name="sales.report.grid.container"> <block type="adminhtml/store_switcher" template="report/store/switcher/enhanced.phtml" name="store.switcher"> <action method="setStoreVarName"><var_name>store_ids</var_name></action> </block> <block type="sales/adminhtml_report_filter_form_order" name="grid.filter.form"> ---- </block> </block> </reference> </adminhtml_report_sales_ereaders> And then copied the needed block,model files from sales and renamed all of them into ereaders under /var/www/magento141/app/code/core/Mage/Adminhtml/. Then placed action for ereaders under /var/www/magento141/app/code/core/Mage/Adminhtml/controllers/Report/SalesController.php public function ereadersAction() { $this->_title($this->__('Reports'))->_title($this->__('Sales'))->_title($this->__('EReaders Sales')); $this->_showLastExecutionTime(Mage_Reports_Model_Flag::REPORT_ORDER_FLAG_CODE, 'ereaders'); $this->_initAction() ->_setActiveMenu('report/sales/ereaders') ->_addBreadcrumb(Mage::helper('adminhtml')->__('EReaders Sales Report'), Mage::helper('adminhtml')->__('EReaders Sales Report')); $gridBlock = $this->getLayout()->getBlock('report_sales_ereaders.grid'); $filterFormBlock = $this->getLayout()->getBlock('grid.filter.form'); $this->_initReportAction(array( $gridBlock, $filterFormBlock )); $this->renderLayout(); } Here when i use var_dump == //var_dump($this-getLayout()-getBlock('report_sales_ereaders.grid')); am getting bool(false) only. It does not call the ereaders grid, instead of its still loading blocks and grids from Sales only. I searched most of the files related to report, am not still able to find out the problem. Hope many of you gone through these sort of issues, please can anyone tell me where am making mistake or missing something.

  • Do I need to manually create indexes for a DBIx::Class belongs_to relationship

    - by Dancrumb
    I'm using the DBIx::Class modules for an ORM approach to an application I have. I'm having some problems with my relationships. I have the following package MySchema::Result::ClusterIP; use strict; use warnings; use base qw/DBIx::Class::Core/; our $VERSION = '1.0'; __PACKAGE__->load_components(qw/InflateColumn::Object::Enum Core/); __PACKAGE__->table('cluster_ip'); __PACKAGE__->add_columns( # Columns here ); __PACKAGE__->set_primary_key('objkey'); __PACKAGE__->belongs_to( 'configuration' => 'MySchema::Result::Configuration', 'config_key'); __PACKAGE__->belongs_to( 'cluster' => 'MySchema::Result::Cluster', { 'foreign.config_key' => 'self.config_key', 'foreign.id' => 'self.cluster_id' } ); As well as package MySchema::Result::Cluster; use strict; use warnings; use base qw/DBIx::Class::Core/; our $VERSION = '1.0'; __PACKAGE__->load_components(qw/InflateColumn::Object::Enum Core/); __PACKAGE__->table('cluster'); __PACKAGE__->add_columns( # Columns here ); __PACKAGE__->set_primary_key('objkey'); __PACKAGE__->belongs_to( 'configuration' => 'MySchema::Result::Configuration', 'config_key'); __PACKAGE__->has_many('cluster_ip' => 'MySchema::Result::ClusterIP', { 'foreign.config_key' => 'self.config_key', 'foreign.cluster_id' => 'self.id' }); There are a couple of other modules, but I don't believe that they are relevant. When I attempt to deploy this schema, I get the following error: DBIx::Class::Schema::deploy(): DBI Exception: DBD::mysql::db do failed: Can't create table 'test.cluster_ip' (errno: 150) [ for Statement "CREATE TABLE `cluster_ip` ( `objkey` smallint(5) unsigned NOT NULL auto_increment, `config_key` smallint(5) unsigned NOT NULL, `cluster_id` char(16) NOT NULL, INDEX `cluster_ip_idx_config_key_cluster_id` (`config_key`, `cluster_id`), INDEX `cluster_ip_idx_config_key` (`config_key`), PRIMARY KEY (`objkey`), CONSTRAINT `cluster_ip_fk_config_key_cluster_id` FOREIGN KEY (`config_key`, `cluster_id`) REFERENCES `cluster` (`config_key`, `id`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `cluster_ip_fk_config_key` FOREIGN KEY (`config_key`) REFERENCES `configuration` (`config_key`) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=InnoDB"] at test_deploy.pl line 18 (running "CREATE TABLE `cluster_ip` ( `objkey` smallint(5) unsigned NOT NULL auto_increment, `config_key` smallint(5) unsigned NOT NULL, `cluster_id` char(16) NOT NULL, INDEX `cluster_ip_idx_config_key_cluster_id` (`config_key`, `cluster_id`), INDEX `cluster_ip_idx_config_key` (`config_key`), PRIMARY KEY (`objkey`), CONSTRAINT `cluster_ip_fk_config_key_cluster_id` FOREIGN KEY (`config_key`, `cluster_id`) REFERENC ES `cluster` (`config_key`, `id`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `cluster_ip_fk_config_key` FOREIGN KEY (`config_key`) REFERENCES `configuration` (`conf ig_key`) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=InnoDB") at test_deploy.pl line 18 From what I can tell, MySQL is complaining about the FOREIGN KEY constraint, in particular, the REFERENCE to (config_key, id) in the cluster table. From my reading of the MySQL documentation, this seems like a reasonable complaint, especially in regards to the third bullet point on this doc page. Here's my question. Am I missing something in the DBIx::Class module? I realize that I could explicitly create the necessary index to match up with this foreign key constraint, but that seems to be repetitive work. Is there something I should be doing to make this occur implicitly?
