  • Can YAML have inheritance?

    - by Jason
    This question involves a lot of symfony but it should be easy enough for someone to follow who only knows YAML and not symfony. My symfony models come from a three-step process: First, I create the tables in MySQL. Second, I run a symfony command (symfony doctrine:build-schema) to convert my table structure into a YAML file. Third, I run another symfony command (symfony doctrine:build-model) to convert the YAML file into PHP code. Here's the problem: there are some tables in the database that I don't want to end up in my symfony code. For example, let's say I have two tables: one called my_table and another called wordpress. The YAML file I end up with might look like this: MyTable: connection: doctrine tableName: my_table Wordpress: connection: doctrine tableName: wordpress That's great except the wordpress table has nothing to do with my symfony models. The result is that every single time I make a change to my database and generate this YAML file, I have to manually remove wordpress. It's annoying! I'd like to be able to create a file called baseConfig.php or something that looks like this: $config = array( 'MyTable' => array( 'connection' => 'doctrine', 'tableName' => 'my_table', ), 'Wordpress' => array( 'connection' => 'doctrine', 'tableName' => 'wordpress', ), ); And then I could have a separate file called config.php or something where I could make modifications to the base config: unset($config['Wordpress']); So my question is: is there any way to convert YAML into executable PHP code (as opposed to load YAML INTO PHP code like what sfYaml::load() does) to achieve this sort of thing? Or is there maybe some other way to achieve YAML inheritance? Thanks, Jason

  • Request for the permission of type 'System.Data.Odbc.OdbcPermission.. help needed

    - by Matt
    I'm getting the following error when trying to connect to a remote mysql server. Request for the permission of type 'System.Data.Odbc.OdbcPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I've installed the odbc 5.1 driver, and can connect to the database using the Data Sources (ODBC) tool in Control Panel. However when I try and run my C# scrip to connect, I get the above error. I've read its something to do with trust levels or something? I don't quite understand what people were talking about though. I went to C:... Framework/v2.0.50727/CONFIG and added to the medium and high trust.config files, but that didn't help.. Can someone help me out here please? My connection string is MyConString = "DRIVER={MySQL ODBC 5.1 Driver};" + "SERVER=" + m_strHost + ";" + "PORT=3306;" + "DATABASE=" + m_strDatabase + ";" + "UID=" + m_strUserName + ";" + "PWD=" + m_strPassword + ";" + "OPTION=3;";

  • CakePHP 1.3 and Uploadifive/Uploadify - Change Upload Filename to a random string

    - by CaboONE
    I have somehow implemented UPLOADIFIVE in my CakePHP application. Everything seems to work great including uploading multiple files and inserting the correct information in the Database. Based on the following code, I would like to UPLOAD AND SAVE EVERY FILE WITH A RANDOM NAME TAKING INTO ACCOUNT THE CURRENT DATE OR SOMETHING SIMILAR. How could I accomplish this? In my Photos Controller I have the following function: // This function is called at every file upload. It uploads the file onto the server // and save the corresponding image name, etc, to the database table `photos`. function upload() { $uploadDir = '/img/uploads/photos/'; if (!empty($_FILES)) { debug($_FILES); $tempFile = $_FILES['Filedata']['tmp_name'][0]; $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; $targetFile = $uploadDir . $_FILES['Filedata']['name'][0]; // Validate the file type $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions $fileParts = pathinfo($_FILES['Filedata']['name'][0]); // Validate the filetype if (in_array($fileParts['extension'], $fileTypes)) { // Save the file move_uploaded_file($tempFile,$targetFile); $_POST['image'] = $_FILES['Filedata']['name'][0]; $this->Photo->create(); if ($this->Photo->save($_POST)) { $this->Session->setFlash($targetFile, 'default', array('class' => 'alert_success')); $this->redirect(array('action' => 'index')); } } else { // The file type wasn't allowed //echo 'Invalid file type.'; $this->Session->setFlash(__('The photo could not be saved. Please, try again.', true)); } } } In my View file - admin_add.ctp I have added the following function $('#file_upload').uploadifive({ 'auto' : false, 'uploadScript' : '/photos/upload', 'buttonText' : 'BROWSE FILES', 'method' : 'post', 'onAddQueueItem' : function(file) { this.data('uploadifive').settings.formData = { 'photocategory_id' : $('#PhotoPhotocategoryId').val() }; } }); <input type="file" name="file_upload" id="file_upload" />

  • I am getting a Radix out of range exception on performing decryption

    - by user3672391
    I am generating a keypair and converting one of the same into string which later is inserted into the database using the following code: KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA"); keyGen.initialize(2048); KeyPair generatedKeyPair = keyGen.genKeyPair(); PublicKey pubkey = generatedKeyPair.getPublic(); PrivateKey prvkey = generatedKeyPair.getPrivate(); System.out.println("My Public Key>>>>>>>>>>>"+pubkey); System.out.println("My Private Key>>>>>>>>>>>"+prvkey); String keyAsString = new BigInteger(prvkey.getEncoded()).toString(64); I then retrieve the string from the database and convert it back to the original key using the following code (where rst is my ResultSet): String keyAsString = rst.getString("privateKey").toString(); byte[] bytes = new BigInteger(keyAsString, 64).toByteArray(); //byte k[] = "HignDlPs".getBytes(); PKCS8EncodedKeySpec encodedKeySpec = new PKCS8EncodedKeySpec(bytes); KeyFactory rsaKeyFac = KeyFactory.getInstance("RSA"); PrivateKey privKey = rsaKeyFac.generatePrivate(encodedKeySpec); On using the privKey for RSA decryption, I get the following exception java.lang.NumberFormatException: Radix out of range at java.math.BigInteger.<init>(BigInteger.java:294) at com.util.SimpleFTPClient.downloadFile(SimpleFTPClient.java:176) at com.Action.FileDownload.processRequest(FileDownload.java:64) at com.Action.FileDownload.doGet(FileDownload.java:94) Please guide.

  • How to use an OSGi service from a web application?

    - by Jaime Soriano
    I'm trying to develop a web application that is going to be launched from a HTTP OSGi service, this application needs to use other OSGi service (db4o OSGi), for what I need a reference to a BundleContext. I have tried two different approaches to get the OSGi context in the web application: Store the BundleContext of the Activator in an static field of a class that the web service can import and use. Use FrameworkUtil.getBundle(this.getClass()).getBundleContext() (being this an instance of MainPage, a class of the web application). I think that first option is completely wrong, but anyway I'm having problems with the class loaders in both options. In the second one it raises a LinkageError: java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/felix/framework/ModuleImpl$ModuleClassLoader) previously initiated loading for a different type with name "com/db4o/ObjectContainer" Also tried with Equinox and I have a similar error: java.lang.LinkageError: loader constraint violation: loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously initiated loading for a different type with name "com/db4o/ObjectContainer" The code that provokes the exception is: ServiceReference reference = context.getServiceReference(Db4oService.class.getName()); Db4oService service = (Db4oService)context.getService(reference); database = service.openFile("foo.db"); The exception is raised in the last line, database class is ObjectContainer, if I change the type of this variable to Object exception is not raised, but It's not useful as an Object :)

  • XMLhttpRequest > PHP > XMLhttpRequest

    - by usurper
    Hi guys, I have another question. XMLhttpRequests haunt me. Everything is now in the database but I need this data to update my page on firt page load or reload. The XHR is triggered in JavaScript file which triggers PHP-Script. PHP-Script access MySQL database. But how do I get the fetched records back into my JavaScript for page update. I can not figure it out. First my synchronous XMLhttpRequest: function retrieveRowsDB() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","retrieveRowData.php", false); xmlhttp.send(null); return xmlhttp.responseText; } Then my PHP-Script: <?php $con = mysql_connect("localhost","root","*************"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("sadb", $con); $data="SELECT * FROM users ORDER BY rowdata ASC"; if (!mysql_query($data,$con)) { die('Error: ' . mysql_error()); } else { $dbrecords = mysql_query($data,$con); } $rowdata = mysql_fetch_array($dbrecords); return $rowdata; mysql_close($con); ?> What am I missing here? Anyone got a clue?

  • Windows 7 64 Bit - ODBC32 - Legacy App Problem

    - by Arturo Caballero
    Good day StackOverFlowlers, I´m a little stuck (really stuck) with an issue with a legacy application on my organization. I have a Windows 7 Enterprise 64 Bit machine, Access 2000 Installed and the Legacy App (Is built with something like VB but older) The App uses System ODBC in order to connect to a SQL 2000 DataBase on a Remote Server. I created the ODCB using C:\Windows\SysWOW64\odbcad32.exe app in order to create a System DSN. I did not use the Windows 7 because it is not visible to the Legacy App. I tested the ODBC connection with Access and worked ok, I can access the remote database. Then I run the legacy App as Administrator and the App can see the ODBC, but I´m getting errors on credential validation and I´m getting this error: DIAG [08001] [Microsoft][ODBC SQL Server Driver][Multi-Protocol]SQL Server does not exist or access denied. (17) DIAG [01000] [Microsoft][ODBC SQL Server Driver][Multi-Protocol]ConnectionOpen (Connect()). (53) DIAG [IM006] [Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed (0) I use Trusted Connection on the ODBC in order to validate the user by Domain Controller. I think that the credentials are not being sent by the Legacy App to the ODBC, or something like that. I don´t have the source code of the Legacy App in order to debug the connection. Also, I turned off the Firewall. Any ideas?? Thanks in advance!

  • Invoking ADO.NET from MATLAB

    - by Andrew Shepherd
    It's possible to call .NET from MATLAB, so I thought I would try to use ADO.NET to connect to a database. I seem to have hit a blocking problem - anytime you try and create a Command object, it throws an error. You can try this yourself: >> NET.addAssembly('System.Data'); >> sqlconn = System.Data.SqlClient.SqlConnection(); >> sqlconn.State ans = Closed >> % So far, so good >> sqlcmd = System.Data.SqlClient.SqlCommand(); ??? Error using ==> System.Data.SqlClient.SqlCommand 'Connection' is already defined as a property. >> Does anyone have some insight into this? It seems like a pure and simple bug on MATLAB's part - maybe it happens with every .NET class that happens to have a property called "Connection". Should I just throw in the towel and give up on using MATLAB to talk to a database using .NET?

  • Android & SQLite: "Table audios has no column named downloaded"

    - by Erik
    I get this weird exception when i run my app on both the emulator and a USB connected device. i can see the table inside the shell, but when I try to insert a record from the Activity acton I get this exception: android.database.sqlite.SQLiteException: table audios has no column named downloaded I am mostly running on an emulator with Android 1.5. The predominant part of my code is linked to this tutorial - http://www.devx.com/wireless/Article/40842/1954.

  • What is a good embeddable Java LDAP server?

    - by LeedsSideStreets
    I'm working on a Java web application that integrates with a few other external applications that are deployed along with it. Authentication information must be synchronized across everything and the other applications want to authenticate against LDAP. The application will be deployed in environments where there will be no other LDAP server for everything to use; I have to provide it. My solution so far has been to use Penrose Server as a standalone app, which I set up to examine tables in the main application's database and publish LDAP based on that. It works well, but it would be nice to have something that can be embedded into the main application itself to simplify deployment. It looks like Penrose can be embedded, but the documentation can be a bit spotty or out-of-date (though it seems to be actively developed). It could be an acceptable solution, but if there is another out there that is known to work well in an embedded configuration I might want to check it out. I'm also concerned about GPL issues with Penrose. I'm not at liberty to GPL the source code for the application. I don't believe it was an issue running it standalone, but embedding it may be no-no... anybody know for sure? A permissive license would be good in order to avoid these issues. Requirements: LDAP v3 Must be able to be have the directory contents updated while running, either programmatically or by another means like syncing with the database as Penrose does Easy to configure (no additional configuration for the app at deployment time would be ideal) So far I've briefly looked at ApacheDS and OpenDS which seem to be embeddable. Does anyone have experience with this kind of thing?

  • Unit Testing - Validation of ViewModel ASP.NET MVC 2

    - by dean nolan
    I am currently unit testing a service that adds users to a repository. I am using dependency injection to test using a fake repository. The repository has a method CreateUser(User user) which just adds it to the database or in this case a List of Users. The logic for the creation is in the UserServices class. The application has a form for creating a user that requires some properties such as name and address. This is an MVC 2 app and I will be using the new validation using data annotations. This makes me wonder about a few things: 1) Should I annotate a POCO object that will map to the database? Or should I create a specific View Model that has these annotations and pass this data to the UserServices class? 2)Should the UserServicesClass also check this data? Would I best be constructing a Usr out of the ViewModel and passing this into the Service as a parameter? 3) The actual unit testing would depend on 2), I either populate a User object and pass that in, or I pass a large list of strings to the method CreateUser. Writing this out I get a basic idea that I should probably annotate the view model only, pass in a user (constructed by the view model if the data is valid) and also just construct the user in the unit test also. Is this the best way to go?

  • Pros & Cons of Google App Engine

    - by Rishi
    Pros & Cons of Google App Engine [An Updated List 21st Aug 09] Help me Compile a List of all the Advantages & Disadvantages of Building an Application on the Google App Engine Pros: 1) No Need to buy Servers or Server Space (no maintenance). 2) Makes solving the problem of scaling much easier. Cons: 1) Locked into Google App Engine ?? 2)Developers have read-only access to the filesystem on App Engine. 3)App Engine can only execute code called from an HTTP request (except for scheduled background tasks). 4)Users may upload arbitrary Python modules, but only if they are pure-Python; C and Pyrex modules are not supported. 5)App Engine limits the maximum rows returned from an entity get to 1000 rows per Datastore call. 6)Java applications may only use a subset (The JRE Class White List) of the classes from the JRE standard edition. 7)Java applications cannot create new threads. Known Issues!! http://code.google.com/p/googleappengine/issues/list Hard limits Apps per developer - 10 Time per request - 30 sec Files per app - 3,000 HTTP response size - 10 MB Datastore item size - 1 MB Application code size - 150 MB Pro or Con? App Engine's infrastructure removes many of the system administration and development challenges of building applications to scale to millions of hits. Google handles deploying code to a cluster, monitoring, failover, and launching application instances as necessary. While other services let users install and configure nearly any *NIX compatible software, App Engine requires developers to use Python or Java as the programming language and a limited set of APIs. Current APIs allow storing and retrieving data from a BigTable non-relational database; making HTTP requests; sending e-mail; manipulating images; and caching. Most existing Web applications can't run on App Engine without modification, because they require a relational database.

  • SQL Server Trouble with Rails

    Ok, I've been trying to get this to work like all day now and I'm barely any further from when I started. I'm trying to get Ruby On Rails to connect to SQL Server.

  • Flash vs. Ajax Abilities

    - by Alex
    Hey everyone. I want to develop an application that does a bunch of cool stuff. The first thing that I need in it is to get information about the page a person is browsing. With that said, I need for example to know how long a user stayed in a page and where was the scrollbar. While getting that data, It's all saved to a database. The thing is, I prefer doing that in Flash [although I have no experience in it] over Ajax since I want to hide the code - which as far as I know not possible in Javascript/Ajax. So, can I do all that in Flash? - Read the content of the page, get the status of the scroll bar.. Plus, I then need to go threw the gathered information that is saved in the database. Since there could be many calculations i thought C++ .Net is better than PHP [which I know better]. Is that all possible or am I just crazy? :) Thanks ahead.

  • What are some techniques to monitor multiple instances of a piece of software?

    - by Geo Ego
    I have a piece of self-serve kiosk software that will be running at multiple sites. I'd like to monitor their status remotely. The kiosk application itself is pretty much finished. I am now in the process of creating a piece of software that will monitor all of the kiosks from a central location so that the customer can view particular details remotely (for instance, how many bills are in the acceptor's cash cartridge, what customer is currently logged in, etc.). Because I am in such an early stage of development, my options are quite open. I understand that I'm not giving very many qualifications, but I'd like to try to get a good variety of potential solutions. Some details: Kiosk software is a VB6 app running on Windows Embedded Monitoring software will be run on a modern desktop version of Windows (either XP, Vista, or 7) Database is SQL Server 2008 My initial idea was to develop a .NET app that would simply report the last database transaction for each kiosk at a set interval (say every second or so) but I'd really like for the kiosk software to report its status directly. I'm not exactly sure where to begin in terms of what modifications may need to be made to the kiosk software, and what the monitoring software will require. Links to articles on these topics would be most welcome.

  • stock management of assemblys and its sub parts

    - by The Disintegrator
    I have to track the stock of individual parts and kits (assembly) and can't find a satisfactory way of doing this. Sample bogus and hyper simplified database: Table prod: prodID 1 prodName Flux capacitor prodCost 900 prodPrice 1350 (900*1.5) prodStock 3 - prodID 2 prodName Mr Fusion prodCost 300 prodPrice 600 (300*2) prodStock 2 - prodID 3 prodName Time travel kit prodCost 1650 (1350+300) prodPrice 2145 (1650*1.3) prodStock 2 Table rels relID 1 relSrc 1 (Flux capacitor) relType 4 (is a subpart of) relDst 3 (Time travel kit) - relID 2 relSrc 2 (Mr Fusion) relType 4 (is a subpart of) relDst 3 (Time travel kit) prodPrice: it's calculated based on the cost but not in a linear way. In this example for costs of 500 or less, the markup is a 200%. For costs of 500-1000 the markup is 150%. For costs of 1000+ the markup is 130% That's why the time travel kit is much cheaper than the individual parts prodStock: here is my problem. I can sell kits or the individual parts, So the stock of the kits is virtual. The problem when I buy: Some providers sell me the Time Travel kit as a whole (with one barcode) and some sells me the individual parts (with a different barcode) So when I load the stock I don't know how to impute it. The problem when I sell: If I only sell kits, calculate the stock would be easy: "I have 3 Flux capacitors and 2 Mr Fusions, so I have 2 Time travel kits and a Flux Capacitor" But I can sell Kits or individual parts. I have to track the stock of the individual parts and the possible kits at the same time (and I have to compensate for the sell price) Probably this is really simple, but I can't see a simple solution. Resuming: I have to find a way of tracking the stock and the database/program is the one who has to do it (I cant ask the clerk to correct the stock) I'm using php+MySql. But this is more a logical problem than a programing one

  • Can't submit new object to WCF DataService because of Primary Key constraint

    - by Rob
    I've got a SQL database that uses Guid's for PK's and upon insert, it generates a NewId(). I have an EF data context setup pointing to that database with the primary keys setup with the Entity key:true, Setter:private and StoreGeneratedPattern:Identity because I want the DB to manage the keys and not have code set the PK property. I have an OData (System.Web.Data.Services.DataService) endpoint to access this data (just like: Hanselman did. I have another app that has a service reference to this service. Upon trying to create a new object from this reference (i.e. Product), the ProductId Primary Key is being defaulted to Guid.Empty when doing var serviceEntities = new ServiceEntities(serviceUri); //OData endpoint var product = new Product(); product.Name = "New Product"; serviceEntities.AddToProducts(product); serviceEntities.SaveChanges(); // error happens here When debugging, I look at the Product.ProductId property and it's set to Guid.Empty. When called SaveChanges, I do not want the ProductId field to be sent to the service. The response I get is: Error processing request stream. Property 'ProductId' is a read-only property and cannot be updated. Please make sure that this property is not present in the request payload. Is there a way to do this or what can I do to get this setup correctly and still have the DB generated the keys. Here is the same setup as the Product example above.

  • What is the proper way to handle non-tracking self tracking entities?

    - by Will
    Self tracking entities. Awesome. Except when you do something like return Db.Users; none of the self-tracking entities are tracking (until, possibly, they are deserialized). Fine. So we have to recognize that there is a possibility that an entity returning to us does not have tracking enabled. Now what??? Things I have tried For the given method body: using (var db = new Database()) { if (update.ChangeTracker.ChangeTrackingEnabled) db.Configurations.ApplyChanges(update); else FigureItOut(update, db); db.SaveChanges(); update.AcceptChanges(); } The following implementations of FigureItOut all fail: db.Configurations.Attach(update); db.DetectChanges(); Nor db.Configurations.Attach(update); db.Configurations.ApplyCurrentValues(update); Nor db.Configurations.Attach(update); db.Configurations.ApplyOriginalValues(update); Nor db.Configurations.Attach(update); db.Configurations.ApplyChanges(update Nor about anything else I can figure to throw at it, other than Getting the original entity from the database Comparing each property by hand Updating properties as needed What, exactly, am I supposed to do with self-tracking entities that aren't tracking themselves??
