  • Django: How to set default language in admin on login

    - by lazerscience
    I'm saving an user's default language in his user profile and on login I want to set the admin's default language to it. One possibility I was thinking of is using a middleware, but I think if I do it on process_request I will not see an user object there since this is processed AFTER the middleware, so I could only set it after the next request! Any solutions are highly appreciated!

  • Can we use JCR API over MySQL?

    - by n_mysql
    Apache Jackrabbit (or the JCR API) helps you separate the data store from the data management system. This would mean that every data store provider would have to implement the JCR API for his own data store. The question is JCR implemented for MySQL? Can we use the JCR API over MySQL? I want to truly abstract out where i store my content, so that tomorrow if i don't want to use a relational DB i can swap it out with the file system with ease.

  • How can I compile an iPhone App with Flash CS5 without a Developer License

    - by manderson12
    I understand Flash CS5 isn't the best way to make an app, but I'd really like to test out the apps I've made with it on my iPhone. Has anyone come up with a way to modify Flash CS5 so it doesn't require a Developer Certificate or Provisioning Profile (like the way you would modify Xcode so you can compile apps without paying $99 for the developer program)? I'd really appreciate it if anyone could provide some help. Thanks in advance.

  • Using OpenID as the only authentication method

    - by iconiK
    I have read the other questions and they mostly talk about the security of doing so. That's not entirely my concern, mostly because the website is question is a browser-based game. However, the larger issue is the user - not every user is literate enough to understand OpenID. Sure RPX makes this pretty easy, which is what I'll use, but what if the user does not have an account at Google or Facebook or whatever, or does not trust the system to log in with an existing account? They'd have to get an account at another provide - I'm sure most will know how to do it, let alone be bothered to do it. There is also the problem of how to manage it in the application. A user might want to use multiple identities with a single account, so it's not as simple as username + password to deal with. How do I store the OpenID identities of a user in the database? Using OpenID gives me a benefit too: RPX can provide extensive profile information, so I can just prefill the profile form and ask the user to edit as required. I currently have this: UserID Email ------ --------------- 86000 [email protected] 86001 [email protected] UserOpenID OpenID ---------- ------ 86000 16733 86001 16839 86002 19361 OpenID Provider Identifier ------ -------- ---------------- 16733 Yahoo https:\\me.yahoo.com\bob#d36bd 16839 Yahoo https:\\me.yahoo.com\bigbobby#x75af 19361 Yahoo https:\\me.yahoo.com\alice#c19fd Is that the right way to store OpenID identifiers in the database? How would I match the identifier RPX gave me with one in the database to log in the user (if the identifier is known). So here are concrete questions: How would I make it accessible to users not having an OpenID or not wanting to use one? (security concerns over say, logging in with their Google account for example) How do I store the identifier in the database? (I'm not sure if the tables above are right) What measures do I need to take in order to prevent someone from logging in as another user and happily doing anything with their account? (as I understand RPX sends the identifier via HTTP, so what anyone would have to do is to just somehow grab it then enter it in the "OpenID" field) What else do I need to be aware of when using OpenID?

  • Reading Foxpro database date field using PHP

    - by Bill Yang
    I've wrote a PHP script to export a Foxpro database to other formats by using ADODB (http://phplens.com/lens/adodb) library to access Foxpro OLE DB provider. Everything worked fine except the date fields are mangled and become like these: 11/17-/2-00 3/4/-20-08 By comparing to actual data I can guess that it is probably in the format of MM/DD/YYYY or m/d/YYYY. How can I properly export the date field?

  • Read excel 2007 file with OLEDB using a specific culture

    - by Derek Ekins
    I am trying to read an excel 2007 file (using OLEDB) that has dates in the UK format. The server is (sometimes) set to US format and so the normal date format problems are in play. This is my connection string: Provider=Microsoft.ACE.OLEDB.12.0;Data Source=myfile.xlsx;Extended Properties="Excel 12.0 Xml;HDR=NO;IMEX=1" I want to ensure that the file is always opened using the en-GB culture. Is there a way to specify the culture using the connection string?

  • Help with OpenSSL request using Python

    - by Ldn
    Hi i'm creating a program that has to make a request and then obtain some info. For doing that the website had done some API that i will use. There is an how-to about these API but every example is made using PHP. But my app is done using Python so i need to convert the code. here is the how-to: The request string is sealed with OpenSSL. The steps for sealing are as follows: • Random 128-bit key is created. • Random key is used to RSA-RC4 symettrically encrypt the request string. • Random key is encrypted with the public key using OpenSSL RSA asymmetrical encryption. • The encrypted request and encrypted key are each base64 encoded and placed in the appropriate fields. In PHP a full request to our API can be accomplished like so: <?php // initial request. $request = array('object' => 'Link', 'action' => 'get', 'args' => array( 'app_id' => 303612602 ) ); // encode the request in JSON $request = json_encode($request); // when you receive your profile, you will be given a public key to seal your request in. $key_pem = "-----BEGIN PUBLIC KEY----- MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBALdu5C6d2sA1Lu71NNGBEbLD6DjwhFQO VLdFAJf2rOH63rG/L78lrQjwMLZOeHEHqjaiUwCr8NVTcVrebu6ylIECAwEAAQ== -----END PUBLIC KEY-----"; // load the public key $pkey = openssl_pkey_get_public($key_pem); // seal! $newrequest and $enc_keys are passed by reference. openssl_seal($request, $enc_request, $enc_keys, array($pkey)); // then wrap the request $wrapper = array( 'profile' => 'ProfileName', 'format' => 'RSA_RC4_Sealed', 'enc_key' => base64_encode($enc_keys[0]), 'request' => base64_encode($enc_request) ); // json encode the wrapper. urlencode it as well. $wrapper = urlencode(json_encode($wrapper)); // we can send the request wrapper via the cURL extension $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://api.site.com/'); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, "request=$wrapper"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $data = curl_exec($ch); curl_close($ch); ?> Of all of that, i was able to convert "$request" and i'v also made the JSON encode. This is my code: import urllib import urllib2 import json url = 'http://api.site.com/' array = {'app_id' : "303612602"} values = { "object" : "Link", "action": "get", "args" : array } data = urllib.urlencode(values) json_data = json.dumps(data) What stop me is the sealing with OpenSSL and the publi key (that obviously i have) Using PHP OpenSSL it's so easy, but in Python i don't really know how to use it Please, help me!

  • Spring JPA and persistence.xml

    - by bmw0128
    I'm trying to set up a Spring JPA Hibernate simple example WAR for deployment to Glassfish. I see some examples use a persistence.xml file, and other examples do not. Some examples use a dataSource, and some do not. So far my understanding is that a dataSource is not needed if I have: <persistence-unit name="educationPU" transaction-type="JTA"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <class>com.coe.jpa.StudentProfile</class> <properties> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" /> <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/COE" /> <property name="hibernate.connection.username" value="root" /> <property name="show_sql" value="true" /> <property name="dialect" value="org.hibernate.dialect.MySQLDialect" /> </properties> </persistence-unit> I can deploy fine, but my EntityManager is not getting injected by Spring. My applicationContext.xml: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="educationPU" /> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" /> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="StudentProfileDAO" class="com.coe.jpa.StudentProfileDAO"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean id="studentService" class="com.coe.services.StudentService"> </bean> My class with the EntityManager: public class StudentService { private String saveMessage; private String showModal; private String modalHeader; private StudentProfile studentProfile; private String lastName; private String firstName; @PersistenceContext(unitName="educationPU") private EntityManager em; @Transactional public String save() { System.out.println("*** em: " + this.em); //em is null this.studentProfile= new StudentProfile(); this.saveMessage = "saved"; this.showModal = "true"; this.modalHeader= "Information Saved"; return "successs"; } My web.xml: <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> Are there any pieces I am missing to have Spring inject "em" in to StudentService?

  • SoapUI JMS Connections

    - by Damo
    I am using SoapUI to do performance testing of some services over JMS using WebSphere MQ as the JMS Provider. SoapUI uses HermesJMS to provide the JMS Connection details for the JMS Endpoint. I've noticed that when I call a request from SoapUI the JMS Connection is never closed. This results in hundreds of SYSTEM.DEF.SVRCONN channel connections. It seems to be specific to SoapUI as HermeJMS doesn't exhibit this behaviour. Has anyone else seen this?

  • Cache aspx page returning an asset on client?

    - by Lieven Cardoen
    How do you cache an aspx page call on the client? The aspx page returns an asset and looks like this: http://srv-edu-build/edumatic3/dev/RetrieveBlob.aspx?assetId=31809&assetFileId=9823 We have tried with Output Cache, with caching in the code behind, but the only result we get is server side caching (by IIS7). In the header of the response cache-control is set to public and expiration time is set (to 14800 as set in output cache profile).

  • Database best practices

    - by user270797
    I have a table which stores comments, the comment can either come from another user, or another profile which are separate entities in this app. My original thinking was that the table would have both user_id and profile_id fields, so if a user submits a comment, it gives the user_id leaves the profile_id blank is this right, wrong, is there a better way?

  • AVFoundation buffer comparison to a saved image

    - by user577552
    Hi, I am a long time reader, first time poster on StackOverflow, and must say it has been a great source of knowledge for me. I am trying to get to know the AVFoundation framework. What I want to do is save what the camera sees and then detect when something changes. Here is the part where I save the image to a UIImage : if (shouldSetBackgroundImage) { CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); // Create a bitmap graphics context with the sample buffer data CGContextRef context = CGBitmapContextCreate(rowBase, bufferWidth, bufferHeight, 8, bytesPerRow, colorSpace, kCGBitmapByteOrder32Little | kCGImageAlphaPremultipliedFirst); // Create a Quartz image from the pixel data in the bitmap graphics context CGImageRef quartzImage = CGBitmapContextCreateImage(context); // Free up the context and color space CGContextRelease(context); CGColorSpaceRelease(colorSpace); // Create an image object from the Quartz image UIImage * image = [UIImage imageWithCGImage:quartzImage]; [self setBackgroundImage:image]; NSLog(@"reference image actually set"); // Release the Quartz image CGImageRelease(quartzImage); //Signal that the image has been saved shouldSetBackgroundImage = NO; } and here is the part where I check if there is any change in the image seen by the camera : else { CGImageRef cgImage = [backgroundImage CGImage]; CGDataProviderRef provider = CGImageGetDataProvider(cgImage); CFDataRef bitmapData = CGDataProviderCopyData(provider); char* data = CFDataGetBytePtr(bitmapData); if (data != NULL) { int64_t numDiffer = 0, pixelCount = 0; NSMutableArray * pointsMutable = [NSMutableArray array]; for( int row = 0; row < bufferHeight; row += 8 ) { for( int column = 0; column < bufferWidth; column += 8 ) { //we get one pixel from each source (buffer and saved image) unsigned char *pixel = rowBase + (row * bytesPerRow) + (column * BYTES_PER_PIXEL); unsigned char *referencePixel = data + (row * bytesPerRow) + (column * BYTES_PER_PIXEL); pixelCount++; if ( !match(pixel, referencePixel, matchThreshold) ) { numDiffer++; [pointsMutable addObject:[NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH - (column/ (float) bufferHeight)* SCREEN_WIDTH - 4.0, (row/ (float) bufferWidth)* SCREEN_HEIGHT- 4.0)]]; } } } numberOfPixelsThatDiffer = numDiffer; points = [pointsMutable copy]; } For some reason, this doesn't work, meaning that the iPhone detects almost everything as being different from the saved image, even though I set a very low threshold for detection in the match function... Do you have any idea of what I am doing wrong?
