  • Django Admin drop down combobox and assigned values

    - by Daniel Garcia
    I have several question for the Django Admin feature. Im kind of new in Django so im not sure how to do it. Basically what Im looking to do is when Im adding information on the model. Some of the fields i want them to be drop-downs and maybe combo-boxes with AutoCompleteMode. Also looking for some fields to have the same information, for example if i have a datatime field I want that information to feed the fields day, month and year from hoti.hotiapp.models import Occurrence from django.contrib import admin class MyModelAdmin(admin.ModelAdmin): exclude = ['reference',] admin.site.register(Occurrence, MyModelAdmin) Anything helps Thanks in advance

  • Google and Mirror Websites

    - by Roberto Aloi
    Which is the best way to manage a website with one or more mirrors so that: Google don't consider it as "dupicated content" The website is correctly indexed No inconsistencies or duplicated information are present in Google Analytics The Google webmaster guidelines in general are respected NOTE: I'm not sure if I should ask this question here or in ServerFault. It looks a bit in the middle between programming and server administration. Let me know if you think ServerFault represent a more appropriate place for this and I'll move it. Thanks.

  • PHP IF condition advise needed

    - by Jose David Garcia Llanos
    I'm using emails as username to login into a site being developed, now if a user updates their email from the profile page, how can i make sure that my email checking statement doesnt catch the user's email as already registered in the database. the page /* Now we will store the values submitted by form in variable */ $fullname=$_POST['fullname']; $dob=$_POST['dob']; $address=$_POST['address']; $myusername=$_POST['myusername']; $telephone=$_POST['telephone']; $queryuser=mysql_query("SELECT * FROM customer WHERE email='$myusername' "); $checkuser=mysql_num_rows($queryuser); if($checkuser != 0) { $Merr[]='&raquo; Sorry this email is already registered!'; } else {$insert_user=mysql_query("UPDATE CUSTOMER SET SYNTAX HERE"); Now these are the fields in question; (name, dob, address, email, telephone) VALUES ('$fullname', '$dob', '$address', '$myusername', '$telephone') As you can see if the user changes the login email then the syntax checks for the email being submitted against the database, however if the user leaves the email unchanged he will get the error because it is found in the database. I was thinking of something like; if($checkuser != 0) { if($myusername == $_POST['myusername']) (...dont show error.) but my php skills are limited. can anyone advise please, thanks

  • How do I connect to mysql from php ?

    - by roberto
    Hi guys. I'm working through examples from a book on php/mysql development. I'm working on a linux/apache environment. I've set up a database and a user. I attempt to connect with this line of code: $db_server = mysql_connect($db_hostname, $db_username, $db_password); I get this error: Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'www-data'@'localhost' (using password: YES) in /var/www/hosts/dj/connect.php on line 3 unable to connect to database: Access denied for user 'www-data'@'localhost' (using password: YES) I can only guess what is happening here: I think www-data is a username for apache. Upon the database connection, the credentials being passed in to mysql are not those of my database user, but rather apache's own credentials. Is that what is happening here? How do I pass in the credentials I've defined for my user ?

  • How can I pass extra parameters to the routeMatch object?

    - by Marcos Garcia
    I'm trying to unit test a controller, but can't figure out how to pass some extra parameters to the routeMatch object. I followed the posts from tomoram at http://devblog.x2k.co.uk/unit-testing-a-zend-framework-2-controller/ and http://devblog.x2k.co.uk/getting-the-servicemanager-into-the-test-environment-and-dependency-injection/, but when I try to dispatch a request to /album/edit/1, for instance, it throws the following exception: Zend\Mvc\Exception\DomainException: Url plugin requires that controller event compose a router; none found Here is my PHPUnit Bootstrap: class Bootstrap { static $serviceManager; static $di; static public function go() { include 'init_autoloader.php'; $config = include 'config/application.config.php'; // append some testing configuration $config['module_listener_options']['config_static_paths'] = array(getcwd() . '/config/test.config.php'); // append some module-specific testing configuration if (file_exists(__DIR__ . '/config/test.config.php')) { $moduleConfig = include __DIR__ . '/config/test.config.php'; array_unshift($config['module_listener_options']['config_static_paths'], $moduleConfig); } $serviceManager = Application::init($config)->getServiceManager(); self::$serviceManager = $serviceManager; // Setup Di $di = new Di(); $di->instanceManager()->addTypePreference('Zend\ServiceManager\ServiceLocatorInterface', 'Zend\ServiceManager\ServiceManager'); $di->instanceManager()->addTypePreference('Zend\EventManager\EventManagerInterface', 'Zend\EventManager\EventManager'); $di->instanceManager()->addTypePreference('Zend\EventManager\SharedEventManagerInterface', 'Zend\EventManager\SharedEventManager'); self::$di = $di; } static public function getServiceManager() { return self::$serviceManager; } static public function getDi() { return self::$di; } } Bootstrap::go(); Basically, we are creating a Zend\Mvc\Application environment. My PHPUnit_Framework_TestCase is enclosed in a custom class, which goes like this: abstract class ControllerTestCase extends TestCase { /** * The ActionController we are testing * * @var Zend\Mvc\Controller\AbstractActionController */ protected $controller; /** * A request object * * @var Zend\Http\Request */ protected $request; /** * A response object * * @var Zend\Http\Response */ protected $response; /** * The matched route for the controller * * @var Zend\Mvc\Router\RouteMatch */ protected $routeMatch; /** * An MVC event to be assigned to the controller * * @var Zend\Mvc\MvcEvent */ protected $event; /** * The Controller fully qualified domain name, so each ControllerTestCase can create an instance * of the tested controller * * @var string */ protected $controllerFQDN; /** * The route to the controller, as defined in the configuration files * * @var string */ protected $controllerRoute; public function setup() { parent::setup(); $di = \Bootstrap::getDi(); // Create a Controller and set some properties $this->controller = $di->newInstance($this->controllerFQDN); $this->request = new Request(); $this->routeMatch = new RouteMatch(array('controller' => $this->controllerRoute)); $this->event = new MvcEvent(); $this->event->setRouteMatch($this->routeMatch); $this->controller->setEvent($this->event); $this->controller->setServiceLocator(\Bootstrap::getServiceManager()); } public function tearDown() { parent::tearDown(); unset($this->controller); unset($this->request); unset($this->routeMatch); unset($this->event); } } And we create a Controller instance and a Request with a RouteMatch. The code for the test: public function testEditActionWithGetRequest() { // Dispatch the edit action $this->routeMatch->setParam('action', 'edit'); $this->routeMatch->setParam('id', $album->id); $result = $this->controller->dispatch($this->request, $this->response); // rest of the code isn't executed } I'm not sure what I'm missing here. Can it be any configuration for the testing bootstrap? Or should I pass the parameters in some other way? Or am I forgetting to instantiate something?

  • Erlang, SSH and authorized_keys

    - by Roberto Aloi
    Playing with the ssh and public_key application in Erlang, I've discovered a nice feature. I was trying to connect to my running Erlang SSH daemon by using a rsa key, but the authentication was failing and I was prompted for a password. After some debugging and tracing (and a couple of coffees), I've realized that, for some weird reason, a non valid key for my user was there. The authorized_keys file contained two keys. The wrong one was at some point in the file, while the correct one was appended at the end of the file. Now, the Erlang SSH application, when diffing the provided key with the ones contained in the authorized_keys, it was finding the first entry (completely ignoring the second on - the correct one). Then, it was switching to different authentication mechanism (at first it was trying dsa instead of rsa and then it was prompting for a password). The question is: Is this behavior intended or should the SSH server check for multiple entries for the same user in the *authorized_keys* file? Is this a generic SSH behaviour or it's just specific to the Erlang implementation?

  • Serialize XML child and keep namespaces in Java

    - by Guido García
    I have an Document object that is modeling a XML like this one: <RootNode xmlns="http://a.com/a" xmlns:b="http://b.com/b"> <Child /> </RootNode> Using Java DOM, I need to get the <Child> node and serialize it to XML, but keeping the root node namespaces. This is what I currently have, but it does not serialize the namespaces: public static void main(String[] args) throws Exception { String xml = "<RootNode xmlns='http://a.com/a' xmlns:b='http://b.com/b'><Child /></RootNode>"; DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder(); Document doc = builder.parse(new ByteArrayInputStream(xml.getBytes())); Node childNode = doc.getFirstChild().getFirstChild(); // serialize to string StringWriter sw = new StringWriter(); DOMSource domSource = new DOMSource(childNode); StreamResult streamResult = new StreamResult(sw); TransformerFactory tf = TransformerFactory.newInstance(); Transformer serializer = tf.newTransformer(); serializer.transform(domSource, streamResult); String serializedXML = sw.toString(); System.out.println(serializedXML); } Current output: <?xml version="1.0" encoding="UTF-8"?> <Child/> Expected output: <?xml version="1.0" encoding="UTF-8"?> <Child xmlns='http://a.com/a' xmlns:b='http://b.com/b' />

  • Propietary modules within GPL and BSD kernels

    - by Francisco Garcia
    Since the Linux kernel is GPL and not LGPL I suppose that it is illegal to link proprietary code to it. How does the industry circumvents this? I would expect that the GPL license will force any developer to release under GPL driver and/or kernel module. Maybe I am confused and implementing a new module is not really linking against the kernel code ??? How do companies deal with this? Maybe linking the other way around (from kernel to their binaries)? On the other hand there is the BSD kernel. Where you are free to link protected IP. Can you get a better design implementing your drivers within a BSD kernel? Is there any design restriction when implementing drivers for GPL kernels?

  • How to trace the connection pool in a Java Web application - DBMS_APPLICATION_INFO

    - by Cleiton Garcia
    Hello, I need improve the traceability in a Web Application that usually run on fixed db user. The DBA should have a fast access for the information about the heavy users that are degrading the database. 5 years ago, I implemented a .NET ORM engine which makes a log of user and the server using the DBMS_APPLICATION_INFO package. Using a wrapper above the connection manager with the following code: DBMS_APPLICATION_INFO.SET_MODULE('" + User + " - " + appServerMachine + "',''); Each time that a connection get a connection from the pool, the package is executed to log the information in the V$SESSION. Has anyone discover or implemented a solution for this problem using the Toplink or Hibernate? Is there a default implementation for this problem? I found here a solutions as I implemented 5 years ago, but I'd like to know with anyone have a better solution and integrated with the ORM. http://stackoverflow.com/questions/53379/using-dbmsapplicationinfo-with-jboss My application is above Spring, the DAO are implemented with JPA (using hibernate) and actually running directly in Tomcat, with plans to (next year) migrate to SAP Netwevare Application Server. Thanks.

  • server|configuration problem, a php script just die with no error log & no reason

    - by Roberto
    Hi (first of all, thanks for your attention & sorry for my bad english hahaha also this is not a programming error, or thats what I think, I think this is an error in some configuration of the server or something else but I dont know what) I have a php script (is running like a process of linux, its not running on the web browser) that send SMS via SMPP on the port 2055 (using sockets in php) & then inserts like 10,000 rows into a dababase on MySQL, the script gets the data from a XML file; firts it was running in a shared server (Hostgator is our hosting provider) & at the begining it worked fine, with no trouble, but 5 months later an error appear, the process just die with no reason, the script only sent & inserted 700 rows in the table of the database & the process didnt show any warning or error, nothing appears in the error logs, & I didnt make any change in the script Hostgator never helped us hahaha so we decided to move the script from the shared server to a dedicated server; I thought it was a memory problem or something like that, but when we move the script to the dedicated server the problem just get worse, the script die when has just sent & inserted 40 to 50 rows to the database the information about this error: the shared server is on Red Hat 4.1.2-46 & the dedicated server is on CentOS 5.4 I have commented the line that sends the SMS, & the problem remains in the shared server, at the begining the script was fine, but then the script started to die when has just inserted 700 aprox. in the database, & now the script is dying when has inserted 2500 rows, its better but we didnt change anything in the dedicated server, the script dies when has just inserted like 40 row in the table the script, before it dies, change to a zombie process & we dont know why the usage of memory appears to be 0.3%, and of the cpu appears to be 0.7% to 1% I have changed the max memory limit of php to 128Mb, and even to -1 (so php wont have any limit) but the problem remains we have the limit of 50 connections of mysql at the same time, so I think this is not the problem Im using mysqli to connect from php to mysql Hostgator report that they haven't made any change or update in the servers what could be the problem?? what should I do??? what should I search??? is something in the logic Im missing?? what steps do I have to follow when managing & searching problems of process on Linux??? thank you very much, I think this is not a programming problem, but you have more experience than me, you can tell me thanks!!! bye!!! :)

  • [PHP] Invalid argument supplied for foreach()

    - by Roberto Aloi
    It often happens to me to handle data that can be either an array or a null variable and to feed some foreach with these data. $values = get_values(); foreach ($values as $value){ ... } When you feed a foreach with data that are not an array, you get a warning: Warning: Invalid argument supplied for foreach() in [...] Assuming it's not possible to refactor the get_values() function to always return an array (backward compatibility, not available source code, whatever other reason), I'm wondering which is the cleanest and most efficient way to avoid these warnings: Casting $values to array Initializing $values to array Wrapping the foreach with an if Other (please suggest)

  • work benefits package [closed]

    - by Francisco Garcia
    For those of you who are into programming not just for the money. I would like to know which benefits you would like to have (or already have). OK, maybe taking away the money factor will limit this question too much. I am surprised to see that most companies have a fixed set for their benefits package. Were you able to negotiate something new or just your salary? What things have you seen out there and/or value most?

  • Overcoming C limitations for large projects

    - by Francisco Garcia
    One aspect where C shows its age is the encapsulation of code. Many modern languages has classes, namespaces, packages... a much more convenient to organize code than just a simple "include". Since C is still the main language for many huge projects. How do you to overcome its limitations? I suppose that one main factor should be lots of discipline. I would like to know what you do to handle large quantity of C code, which authors or books you can recommend.

However git refuses to combine --graph with -g How can reproduce the first sample with a format string which I can further customize?

  • NSOperation inside NSOperationQueue not being executed

    - by Martin Garcia
    I really need help here. I'm desperate at this point. I have NSOperation that when added to the NSOperationQueue is not being triggered. I added some logging to see the NSOperation status and this is the result: Queue operations count = 1 Queue isSuspended = 0 Operation isCancelled? = 0 Operation isConcurrent? = 0 Operation isFinished? = 0 Operation isExecuted? = 0 Operation isReady? = 1 Operation dependencies? = 0 The code is very simple. Nothing special. LoadingConflictEvents_iPad *loadingEvents = [[LoadingConflictEvents_iPad alloc] initWithNibName:@"LoadingConflictEvents_iPad" bundle:[NSBundle mainBundle]]; loadingEvents.modalPresentationStyle = UIModalPresentationFormSheet; loadingEvents.conflictOpDelegate = self; [self presentModalViewController:loadingEvents animated:NO]; [loadingEvents release]; ConflictEventOperation *operation = [[ConflictEventOperation alloc] initWithParameters:wiLr.formNumber pWI_ID:wiLr.wi_id]; [queue addOperation:operation]; NSLog(@"Queue operations count = %d",[queue operationCount]); NSLog(@"Queue isSuspended = %d",[queue isSuspended]); NSLog(@"Operation isCancelled? = %d",[operation isCancelled]); NSLog(@"Operation isConcurrent? = %d",[operation isConcurrent]); NSLog(@"Operation isFinished? = %d",[operation isFinished]); NSLog(@"Operation isExecuted? = %d",[operation isExecuting]); NSLog(@"Operation isReady? = %d",[operation isReady]); NSLog(@"Operation dependencies? = %d",[[operation dependencies] count]); [operation release]; Now my operation do many things on the main method, but the problem is never being called. The main is never executed. The most weird thing (believe me, I'm not crazy .. yet). If I put a break point in any NSLog line or in the creation of the operation the main method will be called and everything will work perfectly. This have been working fine for a long time. I have been making some changes recently and apparently something screw things up. One of those changes was to upgrade the device to iOS 5.1 SDK (iPad). To add something, I have the iPhone (iOS 5.1) version of this application that use the same NSOperation object. The difference is in the UI only, and everything works fine. Any help will be really appreciated. Regards,
