  • Django: accessing session variables from within a template?

    - by AP257
    Hi all If I set a session variable in Django, like: request.session["name"] = "name" Is there a way I can access it from within a template, or do I have to retrieve it from within a view, and then pass it to a template? Asking because I have around 10 little session variables that I'd like to access within a template, and passing all 10 from the view to the template could get a bit messy. (I have to use session variables because it's a HttpResponseRedirect, but storing the variables in a database is overkill for my purposes.) So - any way to grab session variables directly within a template?

  • File Upload drops with no reason

    - by sufoid
    Hallo I want to make an file upload. The script should take the image, resize it and upload it. But it seems that there is any unknown to me error in the upload. Here the code define ("MAX_SIZE","2000"); // maximum size for uploaded images define ("WIDTH","107"); // width of thumbnail define ("HEIGHT","107"); // alternative height of thumbnail (portrait 107x80) define ("WIDTH2","600"); // width of (compressed) photo define ("HEIGHT2","600"); // alternative height of (compressed) photo (portrait 600x450) if (isset($_POST['Submit'])) { // iterate thorugh all upload fields foreach ($_FILES as $key => $value) { //read name of user-file $image = $_FILES[$key]['name']; // if it is not empty if ($image) { $filename = stripslashes($_FILES[$key]['name']); // get original name of file from clients machine $extension = getExtension($filename); // get extension of file in lower case format $extension = strtolower($extension); // if extension not known, output error // otherwise continue if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) { echo '<div class="failure">Fehler bei Datei '. $_FILES[$key]['name'] .': Unbekannter Dateityp: Es können nur Dateien vom Typ .gif, .jpg oder .png hochgeladen werden.</div>'; } else { // get size of image in bytes // $_FILES[\'image\'][\'tmp_name\'] >> temporary filename of file in which the uploaded file was stored on server $size = getimagesize($_FILES[$key]['tmp_name']); $sizekb = filesize($_FILES[$key]['tmp_name']); // if image size exceeds defined maximum size, output error // otherwise continue if ($sizekb > MAX_SIZE*1024) { echo '<div class="failure">Fehler bei Datei '. $_FILES[$key]['name'] .': Die Datei konnte nicht hochgeladen werden: die Dateigröße überschreitet das Limit von 2MB.</div>'; } else { $rand = md5(rand() * time()); // create random file name $image_name = $rand.'.'.$extension; // unique name (random number) // new name contains full path of storage location (images folder) $consname = "photos/".$image_name; // path to big image $consname2 = "photos/thumbs/".$image_name; // path to thumbnail $copied = copy($_FILES[$key]['tmp_name'], $consname); $copied = copy($_FILES[$key]['tmp_name'], $consname2); $sql="INSERT INTO photos (galery_id, photo, thumb) VALUES (". $id .", '$consname', '$consname2')" or die(mysql_error()); $query = mysql_query($sql) or die(mysql_error()); // if image hasnt been uploaded successfully, output error // otherwise continue if (!$copied) { echo '<div class="failure">Fehler bei Datei '. $_FILES[$key]['name'] .': Die Datei konnte nicht hochgeladen werden.</div>'; } else { $thumb_name = $consname2; // path for thumbnail for creation & storage // call to function: create thumbnail // parameters: image name, thumbnail name, specified width and height $thumb = make_thumb($consname,$thumb_name,WIDTH,HEIGHT); $thumb = make_thumb($consname,$consname,WIDTH2,HEIGHT2); } } } } } // current image could be uploaded successfully echo '<div class="success">'. $success .'

  • Where to place java applet policy file?

    - by makdere
    Hi all, I am working on an artificial intelligence project which is a logic game and aims two user connecting to the server on the network who acts as an Admin and then start to play one by one. In order to create connections, i have a server code which is just listening on localhost:8000 and assigning team values to the clients as they arrive. After connecting, clients make their move under Admin's control. The question is that when i try to put my code to work in the browser it fails with the following error: java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:8000 connect,resolve) Even though i have created my own policy, first granting only Socket access permission to the codebase of my project folder (file:///home/xxx/projects/-), after it didnt work i granted all permissions from all codebase. I tried placing my policy file both in the home directory and in the same directory where my applet code resides. Appreciate any tips, thanks.

  • Java synchronized method lock on object, or method?

    - by wuntee
    If I have 2 synchronized methods in the same class, but each accessing different variables, can 2 threads access those 2 methods at the same time? Does the lock occur on the object, or does it get as specific as the variables inside the synchronized method? Example: class x{ private int a; private int b; public synchronized void addA(){ a++; } public synchronized void addB(){ b++; } } Can 2 threads access the same instance of class x performing x.addA() and x.addB() at the same time?

  • DEADLOCK_WRAP error when using Berkeley Db in python (bsddb)

    - by JiminyCricket
    I am using a berkdb to store a huge list of key-value pairs but for some reason when i try to access some of the data later i get this error: try: key = 'scrape011201-590652' contenttext = contentdict[key] except: print the error <type 'exceptions.KeyError'> 'scrape011201-590652' in contenttext = contentdict[key]\n', ' File "/usr/lib64/python2.5/bsddb/__init__.py", line 223, in __getitem__\n return _DeadlockWrap(lambda: self.db[key]) # self.db[key]\n', 'File "/usr/lib64/python2.5/bsddb/dbutils.py", line 62, in DeadlockWrap\n return function(*_args, **_kwargs)\n', ' File "/usr/lib64/python2.5/bsddb/__init__.py", line 223, in <lambda>\n return _DeadlockWrap(lambda: self.db[key]) # self.db[key]\n'] I am not sure what DeadlockWrap is but there isnt any other program or process accessing the berkdb or writing to it (as far as i know,) so not sure how we could get a deadlock, if its referring to that. Is it possible that I am trying to access the data to rapidly? I have this function call in a loop, so something like for i in hugelist: #try to get a value from the berkdb #do something with it I am running this with multiple datasets and this error only occurs with one of them, the largest one, not the others.

  • NHibernate filters don't work with Session.Get

    - by Khash
    I'm trying to implement a Soft-deletable repository. Usually this can be easily done with a Delete Event listener. To filter out the deleted entities, I can add a Where attribute to my class mapping. However, I also need to implement two more methods in the repository for this entity: Restore and Purge. Restore will "undelete" entities and Purge will hard-delete them. This means I can't use Where attribute (since it block out soft-deleted entities to any access) I tried using filters instead. I can create a filter and enable or disable it within session to achieve the same result. But the problem is filters don't have any effect on Session.Get method (they only affect ICriteria based access). Any ideas as to how solve this problem? Thanks

  • Acrobat 8 on Windows 7 64-bit

    - by user66822
    Here's the situation I'm in. I have Acrobat 8 on Wows 7 (64-bit) and anytime I create PDFs any numbers on the page I'm PDFing come through as garbage. Everything else on the page comes out fine, just the numbers are messed up. They appear as random symbols. I've uninstalled, reinstalled. Applied all updates, not applied updates, nothing seems to help. Mayube I'm a bad searcher, can't put in the right search terms, but I can't find anything that seems to point me in a direction on this. ANy ideas?

  • Read OAuth2.0 Signed_Request Facebook Registration C# MVC

    - by Josh
    My question is very similar this but I guess I need to take it one step further. Facebook says "The data is passed to your application as a signed request. The signed_request parameter is a simple way to make sure that the data you're receiving is the actual data sent by Facebook." After a user has logged into my asp c# MVC site and clicked "Register", the redirect-url is http://site/account/register. At that point (the post to the account/register control), I would like to gather the user's information using the signed request so that I can register them with my site locally. I cannot figure out how to access the data facebook makes available. $data = json_decode(base64_url_decode($payload), true); What is the equivalent in C#? What type of variable/data is facebook passing in the post? And how do I access "$payload"?

  • Accessing ArrayBuffer from PHP $_POST after xmlHTTPrequest send()

    - by Dan
    I'm following the tuitions on XMLHttpRequest 2 from : https://developer.mozilla.org/en/DOM/XMLHttpRequest/Sending_and_Receiving_Binary_Data and http://www.html5rocks.com/en/tutorials/file/xhr2/#toc-send-arraybuffer They're great tutorials for the client side, and here is a working extract from my script: var imagebuffer = new ArrayBuffer(size); // create the readonly memory buffer var imagedata= new Uint8Array(imagebuffer); // create a view to manipulate data // do some cool stuff with imagedata var exchange=new XMLHttpRequest(); exchange.open("POST",url,true); exchange.send(arraybuffer); So far so good, and I can see from the both client and server control panels that plenty of data is being transferred. Here's my problem: how do I access the ArrayBuffer with PHP at the server? I'm used to the $_POST superglobal wanting parameters passing from a HTML form so it can be accessed as an array but I can't find any reference for how to access this binary array and stick it in my MySQL database.

  • CodeIgniter's Scaffolding not working

    - by 01010011
    Hi, I keep getting a 404 Page Not Found whenever I try to access CodeIgniter's Scaffolding page in my browser, like so: localhost/codeignitor/index.php/blog/scaffolding/mysecretword I can access localhost/codeignitor/index.php/blog just fine. I followed CodeIgnitor's instructions in their "Create a blog in 20 minutes" by storing my database settings in the database.php file; and automatically connecting to the database by inserting "database" in the core array of the autoload.php; and I've added both parent::Controller(); and $this-load-scaffolding('myTableName') to blog's constructor. It still gives me this 404. Any suggestions?

  • Restrict a port to a single app

    - by viraptor
    I'd like to restrict a range of udp ports to a single application (or a user). What I'd like to achieve is not simply blocking a bind() from other uids, but also remove the range from a pool that can be auto-assigned. For example, if someone tries to explicitly bind 12345, but doesn't run the specified app, they should get EPERM. If someone tries to bind an unspecified port, they should never try to bind 12345 at random. Is there any system that can help here? I tried browsing apparmor / selinux docs, but they seem to do the blocking part only.

  • Accessing rails flash[:notice] in a model

    - by titaniumdecoy
    I am trying to assign a message to flash[:notice] in a model observer. This question has already been asked: Ruby on Rails: Observers and flash[:notice] messages? However, I get the following error message when I try to access it in my model: undefined local variable or method `flash' for #<ModelObserver:0x2c1742c> Here is my code: class ModelObserver < ActiveRecord::Observer observe A, B, C def after_save(model) puts "Model saved" flash[:notice] = "Model saved" end end I know the method is being called because "Model saved" is printed to the terminal. Is it possible to access the flash inside an observer, and if so, how?

  • How to determine whether a .NET exception is being handled?

    - by romkyns
    We're investigating a coding pattern in C# in which we'd like to use a "using" clause with a special class, whose Dispose() method does different things depending on whether the "using" body was exited normally or with an exception. To the best of my understanding, the CLR keeps track of the current exception being handled until it's been consumed by a "catch" handler. However it's not entirely clear whether this information is exposed in any way for the code to access. Do you know whether it is, and if so, how to access it? For example: using (var x = new MyObject()) { x.DoSomething(); x.DoMoreThings(); } class MyObject : IDisposable { public void Dispose() { if (ExceptionIsBeingHandled) Rollback(); else Commit(); } } This looks almost like System.Transactions.TransactionScope, except that success/failure is not determined by a call to x.Complete(), but rather based on whether the using body was exited normally.

  • SELECT INTO or Stored Procedure?

    - by Kerry
    Would this be better as a stored procedure or leave it as is? INSERT INTO `user_permissions` ( `user_id`, `object_id`, `type`, `view`, `add`, `edit`, `delete`, `admin`, `updated_by_user_id` ) SELECT `user_id`, $object_id, '$type', 1, 1, 1, 1, 1, $user_id FROM `user_permissions` WHERE `object_id` = $object_id_2 AND `type` = '$type_2' AND `admin` = 1 You can think of this with different objects, lets say you have groups and subgroups. If someone creates a subgroup, it is making everyone who had access to the parent group now also have access to the subgroup. I've never made a stored procedure before, but this looks like it might be time. This call be probably be called very often. Should I be creating a procedure or will the performance be insignificant?

  • What is a proper way to store site-level global variables in a SharePoint site?

    - by ccomet
    One thing that has driven me nuts about SharePoint2007 is the apparent inability to have defineable settings that apply specifically to a site or site collection itself, and not the content. I mean, you have some pre-defined settings like the Site Logo, the Site Name, and various other things, but there doesn't appear to be anywhere to add new kinds of settings. The application I am working on needs to be able to create multiple kinds of "project site collections" that all follow a basic template, but have certain additional settings that apply specifically to that site collection and that one alone. In addition to the standard site name we also need to define the Project Number, the Project Name, and the Client Name. And given the requests of some of our clients, we also reach a point where we have to have configurable settings that alter how some of the workflows work, like whether files are marked with Letters or Numbers. Our current solution, which I'm hesitant about, has been to store an XML file on the SharePoint server. This file contains one node for each site collection, identified by the URL of the root site. Inside the node are all of the elements that need to be defined for that site collection. When we need them, we have to access the XML file (which will always require SPSecurity.RunWithElevatedPrivileges to access files right on the server) every time to load it and retrieve the data. There are a lot of automated processes which will have to do this, and I'm hesitant about the stability of this method when we reach hundreds of sites with thousands of files running tens of thousands of workflows, all wanting to access this file. Maybe they're unfounded worries, but I'd rather worry than risk everything breaking in a couple years. I was looking into the SPWeb object and found the AllProperties hashtable. It looks like just the kind of thing which might work, but I don't know how safe it is to be modifying this. I read through both MSDN and the WSS SDK but found nothing that clarified on adding completely new properties into AllProperties. Is it safe to use AllProperties for this kind of thing? Or is there yet another feature that I am missing, which could handle the concept of global variables at the site collection or site scope?

  • How do I mount an Exchange mail store from the Windows Command Line?

    - by Cypher
    Our Exchange server is running Exchange Server 2003 Standard on the Windows Server 2003 platform. We're dealing with the mail store size issue, where if the mail store goes over the limit, it gets dismounted. While we are working with the powers-that-be on a policy that will prevent this happening in the future, I would like to see if it is possible to re-mount the mail store via the Windows CLI. I'm already monitoring the Event Logs and alerting on mail store warnings and dismounts - I'm just tired of getting up at 5am to manually re-mount the store while the political wars ensue. My alerting tools have the ability to execute a batch script when an alert is generated. I would greatly prefer a native CLI option. I'm not too keen on running some random vbscript found on the Internet and I don't really care to spend my time debugging someone else's code. PowerShell might be an option, if it can be triggered from the CLI.

  • Sendmail.mc: alias all incoming e-mails to one account

    - by Angus
    I need to alias all mail coming from another SMTP server to this one account "myinbox". The system in question is to receive all e-mail on the domain, if that's any help. http://william.shallum.net/random-notes/sendmailredirectallmailfordevelopment is a template for the beginning of a solution, but that routes everything (including outgoing and internal mail) to that one account, and trying to understand how these R rules work is making my head spin. I think the answer is in sendmail.mc rather than any Procmail configuration. So I think what I generally don't want the filter to do is: Interfere w/any outgoing e-mail Interfere w/any internal e-mail Sometimes some cron job causes "root" to mail to "root". I don't want these to go to myinbox. Cause infinite loops Who does? Bounce messages and any DSNs come to mind. I'm running Sendmail 8.13.1 and Procmail 3.22.

  • My site was recently attacked. What do I do?

    - by ChrisH
    This is a first for me. One of the sites I run was recently attacked. Not at all an intelligent attack - pure brute force - hit every page and every non-page with every extension possible. Posted with garbage data to every form and tried to post to some random urls too. All tod, 16000 requests in one hour. What should I do to prevent/alert this kind of behavior? Is there a way to limit the request/hr for a given ip/client? Is there a place I should be reporting the user to? They appear to be from China and did leave what seems like a valid e-mail.

  • Troubleshoot odd large transaction log backups...

    - by Tim
    I have a SQL Server 2005 SP2 system with a single database that is 42gigs in size. It is a modestly active database that sees on average 25 transactions per second. The database is configured in Full recovery model and we perform transaction log backups every hour. However it seems to be pretty random at some point during the day the log backup will go from it's average size of 15megs all the way up to 40gigs. There are only 4 jobs that are scheduled to run on the SQL server and they are all typical backup jobs which occur on a daily/weekly basis. I'm not entirely sure of what client activity takes place as the application servers are maintained by a different department. Is there any good way to track down the cause of these log file growths and pinpoint them to a particular application, or client? Thanks in advance.

  • updating batches of data

    - by gaponte69
    I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database... Any suggestions are welcomed... I've used some good links, but very helpful, like: http://www.asp.net/learn/data-access/tutorial-63-cs.aspx http://www.asp.net/learn/data-access/tutorial-66-cs.aspx etc...

  • How to store private pictures and videos in Ruby on Rails

    - by TK
    Here's a story: User A should be able to upload an image. User A should be able to set a privacy. ("Public" or "Private"). User B should not be able to access "Private" images of User A. I'm planning to user Paperclip for dealing with uploads. If I store the images under "RAILS_ROOT/public/images", anyone who could guess the name of the files might access the files. (e.g., accessing http://example.com/public/images/uploads/john/family.png ) I need to show the images using img tags, so I cannot place a file except public. How can I ensure that images of a user or group is not accessible by others?

  • In Java, is there a way to obtain the command line parameters even if main() didn't save them?

    - by Uri
    We have a program with a main() that parses certain CLPs but does not save them anywhere. I then have my own plug-in code that needs access to the original CLPs (so I can transmit more parameters) for it. However, I cannot change main() I saw that there is apparently a way to do this in C#, I'm looking for an equivalent Java solution on Linux. UPDATE: Obviously, I'm aware of how main() works. Unfortunately, I cannot change the existing application or the way it is invoked (except for CLPs). I can only access via a sandboxed plugin code. My question is whether there is a way to get the command line (rather then the environment variables with -D) that the JVM was invoked with.

  • what database should i choose ?

    - by MemoryLeak
    I use winforms to develop a desktop application, and right now I plan to use SQL server express, but the problem is, if i use sql server express, then the installation is much trouble, i need to install sql server first, and install my own applicaiton. Then I tried to use access 2003 as my database, then I only need to copy the mdb file with my application. But the access 's function is not that strong, the text length is limited to 255 byte. Is there any other database solution, which is easy to integrate to my application, and easy to install after i develop my application ? Many many desktop application have their own database, and easy to install and easy to use, what database do they use ?
