  • How do I create an empty Django formset using modelformset_factory?

    - by nbolton
    I'm creating a formset, but it seems to populate it with all of the existing data in the table for that object. I can't figure out how to start with a blank formset; the only way seems to be to delete all of the data from the table, but clearly this isn't an option. I will post code if necessary (but there's lots of it, so knowing what is relevant is tricky).

  • Django Form field initial value on failed validation

    - by John
    Hi, how do I set the value of a field element after a form has been submitted but has failed validation? e.g. if form.is_valid(): form.save() else: form.data['my_field'] = 'some different data' I don't really want to put it in the view though and would rather have it as part of the form class. Thanks

  • Tomcat Load Balalncing - Programatic Parameter Based ??

    - by Gala101
    Here's the scenario: Many users access an application (running on tomcat), the user's data is segmented into multiple databases, say each db containing 1000 user's data. Now is it somehow possible to have 100s of tomcat servers running on 'inexpensive' PC class machines with each connecting to a single db, with user's session getting passed to appropriate tomcat and becoming 'Sticky' there. Can have some sort of 'gateway' deciding which user goes where and doing the load-balancing appropriately. Would make a great scalability solution :)

  • JSON image viewer not working in firefox

    - by jarga
    I have tried to find out why JSON is not working in Firefox all over this forum and the internet. It works on tablets, ie, safari. It works on my desktop in firefox. It only does not work after uploading I've tried a few things (commented out), such as mimeType with no solution. I have tried using the $.ajax with no better luck. Firefox had no javascript errors. I'm using jQuery 1.7. Console.log is printing out the data. $(document).ready(function(){ jQuery.support.cors = true; //$.ajaxSetup({ mimeType: "application/json" }); /*$.ajaxSetup({ scriptCharset: "utf-8" , contentType: "application/json; charset=utf-8"}); */ // loading pictures $.getJSON("intro.json?format=json", function(data){ var links = ''; var imageload = ''; var title = ''; console.log(data) $.each(data, function(key, item){ links += ' <a href=' + item.image + '>' + key + '</a>'; imageload += '<img src="' + item.image + ' " />'; title += item.alt; }); $('.introCon').html(imageload); $('.introCon img').hide(); $('.introCon img:last').fadeIn(500); $('.introCon img').fadeIn(1000); rotatePics(2); }); }); function rotatePics(currentPhoto) { var numberOfPhotos = $('.introCon img').length; currentPhoto = currentPhoto % numberOfPhotos; $('.introCon img').eq(currentPhoto).fadeOut( function() { // re-order the z-index $('.introCon img').each(function(i) { $(this).css( 'zIndex', ((numberOfPhotos - i) + currentPhoto) % numberOfPhotos ); }); $(this).show(); setTimeout(function() {rotatePics(++currentPhoto);}, 3000); }); } Here is the simple JSON from a separate file. { "1" : { "image" : "portfolio/chrpic.png", "alt" : "Blah.", "detail": "Quartz"}, "2" : { "image" : "portfolio/mysspic.png", "alt" : "Landing page.", "detail": "Container"}, "3" : { "image" : "portfolio/decode-pic3.png", "alt" : "Decode this.", "detail": "Landing page 2"}, "4" : { "image" : "portfolio/simple-think-pic.png", "alt" : "Simple Think", "detail": "simpilify your life"} }

  • Flex DataGrid with row number column

    - by philcruz
    I want to extend the DataGrid component so that there is a (read-only) column for the row number like you see in spreadsheets. I came across this article http://www.cflex.net/showFileDetails.cfm?ObjectID=735 but it depends on the data being unique for each row so that it can index into the array. If the data is not unique (like for an empty grid) it doesn't work. How can I implement that?

  • How to convert string to XML object in JavaScript?

    - by Jack Roscoe
    Hi, I am aware of this question already existing, but it has given me no luck. I have an application which loads a physicial XML document via the following method: jQuery.ajax( { type: "GET", url: fileName, dataType: "xml", success: function(data) { etc... I parse the XML and convert it into a string which is saved into a variable so that it can easily be stored in a database. How can I now convert the data in this variable back into an XML object so that it can be parsed as such?

  • How do I create a safe local development environment?

    - by docgnome
    I'm currently doing web development with another developer on a centralized development server. In the past this has worked alright, as we have two separate projects we are working on and rarely conflict. Now, however, we are adding a third (possible) developer into the mix. This is clearly going to create problems with other developers changes affecting my work and vice versa. To solve this problem, I'm thinking the best solution would be to create a virtual machine to distribute between the developers for local use. The problem I have is when it comes to the database. Given that we all develop on laptops, simply keeping a local copy of the live data is plain stupid. I've considered sanitizing the data, but I can't really figure out how to replace the real data, with data that would be representative of what people actually enter with out repeating the same information over and over again, e.g. everyone's address becomes 123 Testing Lane, Test Town, WA, 99999 or something. Is this really something to be concerned about? Are there tools to help with this sort of thing? I'm using MySQL. Ideally, if I sanitized the db it should be done from a script that I can run regularly. If I do this I'd also need a way to reduce the size of the db itself. (I figure I could select all the records created after x and whack them and all the records in corresponding tables out so that isn't really a big deal.) The second solution I've thought of is to encrypt the hard drive of the vm, but I'm unsure of how practical this is in terms of speed and also in the event of a lost/stolen laptop. If I do this, should the vm hard drive file itself be encrypted or should it be encrypted in the vm? (I'm assuming the latter as it would be portable and doesn't require the devs to have any sort of encryption capability on their OS of choice.) The third is to create a copy of the database for each developer on our development server that they are then responsible to keep the schema in sync with the canonical db by means of migration scripts or what have you. This solution seems to be the simplest but doesn't really scale as more developers are added. How do you deal with this problem?

  • SQL Server Replication Backup

    - by user18039
    Hi We have a new system that runs on SQL Server 2008 r2 64-bit. There is a primary on-line transactional processing (OLTP) database that accepts a high volume of updates from several thousand Point of Sale systems at stores around the country. In order to protect this vital function, I have decided to introduce a dedicated reporting database server - from which multiple users will run some pretty complex reports. I realise that there were a number of choices but I decided to use Transaction Replication as the mechanism for copying the data from the OLTP database to the new reporting database - one way replication. The solution has worked well in test. I'm now being asked what changes need to be made to the backup policy to cover the architectural changes. I have read pages such as MSDN:Strategies for Backing Up and Restoring Snapshot and Transactional Replication but I think these are overkill for my solution. In fact, my current thinking is that we simply need to continue making backups of the OLTP data and logs. If the Reporting db or any of the system replication (eg distribution) databases fail then it's no big deal - we can clear all down then re-create the replication. I realise that taking a complete snapshot of the OLTP would be time consuming (approx 5 hours) but I'd be more relaxed about this that trying to restore backups of the various data and log files in the correct sequence. My view is that the complex strategies set out in the MSDN article would only be the way to go for a more complex replication solution than I have, eg if there were multiple subscribers with 2-way replication. Would you agree? I'd be grateful for any advice. Many thanks, Rob.,

  • Cassandra replication system - how it works

    - by inquisitor
    Does cassandra replicates only on write procedure (with choosen consistency level)? Is there any auto-replicate option for absent nodes, if i want symetric data in every node? If I plug in new node to cluster there is no auto replication - how to sync data from others nodes with new one? If I want replication like multimaster (2 nodes) with slave backup (1 node) known from MySQL, what is the proper logic setup and manage that on cassandra (3 nodes)? How about two nodes?

  • Preferred Options for Webservice to Android

    - by Tim Almond
    I need to get an Android app to interface with an XML webservice (it's really just a request which returns XML), but as the data is large and includes some things I don't need (like a huge description block), I was thinking of transforming it via a server into a format that would be good for Android, and also to be reduced considering it will be used in a low bandwidth area. Does anyone have any suggestions for a good lightweight protocol? I'm especially thinking about libraries for Android that already exist for say REST or even delimited data.

  • How to delete removed devices from a mdadm RAID1?

    - by Kabuto
    I had to replace two hard drives in my RAID1. After adding the two new partitions the old ones are still showing up as removed while the new ones are only added as spare. I've had no luck removing the partitions marked as removed. Here's the RAID in question. Note the two devices (0 and 1) with state removed. $ mdadm --detail /dev/md1 mdadm: metadata format 00.90 unknown, ignored. mdadm: metadata format 00.90 unknown, ignored. /dev/md1: Version : 00.90 Creation Time : Thu May 20 12:32:25 2010 Raid Level : raid1 Array Size : 1454645504 (1387.26 GiB 1489.56 GB) Used Dev Size : 1454645504 (1387.26 GiB 1489.56 GB) Raid Devices : 3 Total Devices : 3 Preferred Minor : 1 Persistence : Superblock is persistent Update Time : Tue Nov 12 21:30:39 2013 State : clean, degraded Active Devices : 1 Working Devices : 3 Failed Devices : 0 Spare Devices : 2 UUID : 10d7d9be:a8a50b8e:788182fa:2238f1e4 Events : 0.8717546 Number Major Minor RaidDevice State 0 0 0 0 removed 1 0 0 1 removed 2 8 34 2 active sync /dev/sdc2 3 8 18 - spare /dev/sdb2 4 8 2 - spare /dev/sda2 How do I get rid of these devices and add the new partitions as active RAID devices? Update I seem to have gotten rid of them. My RAID is resyncing, but the two drives are still marked as spares and are number 3 and 4, which looks wrong. I'll have to wait for the resync to finish. All I did was to fix the metadata error by editing my mdadm.conf and rebooting. I tried rebooting before, but this time it worked for whatever reason. Number Major Minor RaidDevice State 3 8 2 0 spare rebuilding /dev/sda2 4 8 18 1 spare rebuilding /dev/sdb2 2 8 34 2 active sync /dev/sdc2

  • Multiple SSL certificates on Apache using multiple public IPs - not working

    - by St. Even
    I need configure multiple SSL certificates on a single Apache server. I already know that I need multiple external IP addresses as I cannot use SNI (only running Apache 2.2.3 on this server). I assumed that I had everything configured correctly, unfortunately things are not working as they should (or maybe I should say, as I expected them to work)... In my httpd.conf I have: NameVirtualHost *:80 NameVirtualHost *:443 Lets say my public IP is 12.0.0.1 and my private IP is 192.168.0.1. When I use the public IP in my vhost my default website is being shown instead the one defined in my vhost, e.g.: <VirtualHost 12.0.0.1:443> ServerAdmin [email protected] ServerName blablabla.site.com DocumentRoot /data/sites/blablabla.site.com ErrorLog /data/sites/blablabla.site.com-error.log #CustomLog /data/sites/blablabla.site.com-access.log common SSLEngine On SSLCertificateFile /etc/httpd/conf/ssl/blablabla.site.com.crt SSLCertificateKeyFile /etc/httpd/conf/ssl/blablabla.site.com.key SSLCertificateChainFile /etc/httpd/conf/ssl/blablabla.site.com.ca-bundle <Location /> SSLRequireSSL On SSLVerifyDepth 1 SSLOptions +StdEnvVars +StrictRequire </Location> </VirtualHost> When I use the private IP in my vhost everything works as it should (the website defined in my vhost is being shown), e.g.: <VirtualHost 192.168.0.1:443> ...same as above... </VirtualHost> My server is listening on all interfaces: [root@grbictwebp02 httpd]# netstat -tulpn | grep :443 tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 5585/httpd What am I doing wrong? If I cannot get this to work I cannot continue to add the second SSL certificate on the other public IP... If more information is required just let me know!

  • Incorrect string encodings

    - by James
    Note: I have read all of the related PHP, UTF-8, character encoding articles that are usually suggested, but my question relates to data inserted before I applied such techniques. I am wishing to retrospectively fix all character encoding problems. Now all connections are set as utf8 using PDO. PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8' Unfortunately, a large amount of data was inserted that is of questionable encoding before I had implemented correct character encoding practices. As displayed by: $sql = "SELECT name FROM data LIMIT 3"; foreach ($pdo->query($sql) as $row) { $name = $row['name']; echo $name . "\n"; echo utf8_encode($name) . "\n"; echo utf8_decode($name) . "\n"; echo htmlspecialchars($name, ENT_QUOTES, 'UTF-8') . "\n"; echo htmlspecialchars(utf8_encode($name), ENT_QUOTES, 'UTF-8') . "\n"; echo htmlspecialchars(utf8_decode($name), ENT_QUOTES, 'UTF-8') . "\n"; echo '<hr/>'; } Which produces: Antonín Dvořák AntonÃÆÃ­n DvoÃâ¦Ãâ¢ÃÆÃ¡k Anton??­n Dvo??????¡k Antonín Dvořák AntonÃÆÃ­n DvoÃâ¦Ãâ¢ÃÆÃ¡k ---------- Ô±Ö€Õ¡Õ´ Ô½Õ¡Õ¹Õ¡Õ¿Ö€ÕµÕ¡Õ¶ ñÃâ¬Ã¡Ã´ ýáùáÿÃâ¬ÃµÃ¡Ã¶ ????? ?????????? Ô±Ö€Õ¡Õ´ Ô½Õ¡Õ¹Õ¡Õ¿Ö€ÕµÕ¡Õ¶ ñÃâ¬Ã¡Ã´ ýáùáÿÃâ¬ÃµÃ¡Ã¶ ---------- Tiësto Tiësto Tiësto Tiësto Tiësto Tiësto ---------- When removing 'SET NAMES utf8' with PDO it produces the data: Antonín DvoÅák Antonín DvoÃÂák Antonín Dvorák Antonín DvoÅák Antonín DvoÃÂák Antonín Dvorák ---------- ???? ????????? Ô±ÖÕ¡Õ´ Ô½Õ¡Õ¹Õ¡Õ¿ÖÕµÕ¡Õ¶ ???? ????????? ???? ????????? Ô±ÖÕ¡Õ´ Ô½Õ¡Õ¹Õ¡Õ¿ÖÕµÕ¡Õ¶ ???? ????????? ---------- Tiësto Tiësto Ti?sto Tiësto Tiësto ---------- And here is a dump of the database rows concerned: DROP TABLE IF EXISTS `data`; CREATE TABLE IF NOT EXISTS `data` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `name` varchar(80) NOT NULL, PRIMARY KEY (`id`), KEY `name` (`name`(10)), ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=0; INSERT INTO `data` (`id`, `name`) VALUES (0, 'Antonín Dvořák'), (1, 'Ô±Ö€Õ¡Õ´ Ô½Õ¡Õ¹Õ¡Õ¿Ö€ÕµÕ¡Õ¶'), (2, 'Tiësto'); The 3rd and 6th lines of the 3rd row "Tiësto" are then correctly echoed. I'm just unsure what is the best way to correct encodings/detect the encodings of bad strings and correct, etc.
