  • Winforms control that works like ajax tag-completion

    - by Sargola
    Heya, I want to create a winforms app where you can assign tags to an entity. ofc I want the customer to re-use existing tags a lot. That's why I want to show them the list of tags while they are typing (similar to intellisense in VS and the tags-dropdown even here in stackoverflow ;)) do you have any control(s) in mind that offers this functionality? can I reuse a ComboBox for this? (here I need to drop it down programatically - how?) I want to have the taglist getting input-focus but not lose the mainform-focus, and I want it to be on top over all windows and even range out of the mainform-area (like intellisense in vs) thx!

  • Association and model data saving problem

    - by Zhlobopotam
    Developing with cakephp 1.3 (latest from github). There are 2 models bind with hasAndBelongsToMany: documents and tags. Document can have many tags in other words. I've add a new document submitting form there user can enter a list of tags separated with commas (new tag will be added, if not exist already). I looked at cakephp bakery 2.0 source code on github and found the solution. But it seems that something is wrong. class Document extends AppModel { public $hasAndBelongsToMany = array('Tag'); public function beforeSave($options = array()) { if (isset($this->data[$this->alias]['tags']) && !empty($this- >data[$this->alias]['tags'])) { $tagIds = $this->Tag->saveDocTags($this->data[$this->alias] ['tags']); unset($this->data[$this->alias]['tags']); $this->data[$this->Tag->alias][$this->Tag->alias] = $tagIds; } return true; } } class Tag extends AppModel { public $hasAndBelongsToMany = array ('Document'); public function saveDocTags($commalist = '') { if ($commalist == '') return null; $tags = explode(',',$commalist); if (empty($tags)) return null; $existing = $this->find('all', array( 'conditions' => array('title' => $tags) )); $return = Set::extract($existing,'/Tag/id'); if (sizeof($existing) == sizeof($tags)) { return $return; } $existing = Set::extract($existing,'/Tag/title'); foreach ($tags as $tag) { if (!in_array($tag, $existing)) { $this->create(array('title' => $tag)); $this->save(); $return[] = $this->id; } } return $return; } } So, new tags creation works well but document model can't save association data and tells: SQL Error: 1054: Unknown column 'Array' in 'field list' Query: INSERT INTO documents (title, content, shortnfo, date, status) VALUES ('Document with tags', '', '', Array, 1) Any ideas how to solve this problem?

  • How do I use IPTC/EXIF metadata to categorise photos?

    - by kbro
    Many photo viewing and editing applications allow you to examine and change EXIF and IPTC data in JPEG and other image files. For example, I can see things like shutter speed, aperture and orientation in the picture files that come off my Canon A430. There are many, many name/value pairs in all this metadata. But... What do I do if I want to store some data that doesn't have a build-in field name. Let's say I'm photographing an athletics competition and I want to tag every photo with the competitor's bib number. Can I create a "bib_number" field and assign it a values of "0001", "5478", "8124" etc, and then search for all photos with bib_number="5478"? I've spent a few hours searching and the best I can come up with is to put this custom information in the "keywords" field but this isn't quite what I'm after. With this socution I'd have to craft a query like "keywords contains bib_number_5478" whereas what I want it "bib_number is 5478". So do the EXIF and/or IPTC standards allow addtional user-defined field names? Thanks Kev

  • Is it possible to have an inconsistent branch/tag with SVN due to concurrent commit action?

    - by maraspin
    I'm trying to understand whether subversion has its own mechanisms for regulating concurrent user activities on the trunk (IE a branch/tag action and a commit action happening at the same time) or if it's up to the users to sync between themselves before acting on the trunk. I've been trying to find documentation about this on the net but haven't been able to come up with something, so I appreciate if someone can enlighten me on the topic. Thank you in advance!

  • WPF Create Rectangle Tags on Image from DataBinding

    - by Noah
    I'm trying to add image tags to a WPF image and I'm not having much luck. I'd like to do it through databinding if at all possible. Can I set a resource with a DataTemplate to take care of this? Here's what I've been playing with to no avail: <Image Margin="25,4,14,46" Name="MainImage" Stretch="Uniform" MouseDown="MainImage_MouseDown" Grid.Row="1" HorizontalAlignment="Left" VerticalAlignment="Top" Source="{Binding Path=FileName}" > <Image.Resources> <DataTemplate DataType="{x:Type capp:CAPMeta}"> <Label Content="{Binding Path=TagText}"> </Label> </DataTemplate> </Image.Resources> </Image> Thanks!

  • Database Schema for Machine Tags?

    - by Gabriel
    Machine tags are more precise tags: http://www.flickr.com/groups/api/discuss/72157594497877875. They allow a user to basically tag anything as an object in the format object:property=value Any tips on a rdbms schema that implements this? Just wondering if anyone has already dabbled with this. I imagine the schema is quite similar to implementing rdf triples in a rdbms

    - by poseid
    I am using the plugin: http://github.com/karmi/is_taggable How can I perform simple statistics on my tags, e.g. what's the most used tag? which tags are not used, etc.? With SQL I would do something like: select id, count(*) from taggings group by taggable_id; But I am not seeing how to do this with the plugin. Thanks!

  • How do I determine what branch/tag I have checked out in git?

    - by Avry
    I clone my source using git clone https://gerrit.wikimedia.org/r/p/mediawiki/core.git w/. Then I specify a specific branch/tag by doing git checkout <tag name> or git checkout origin/REL<release number>. Sometimes I forget what branch or tag I'm on. In SVN I would do a svn info to figure out what branch/tag I'm using (I realize that git has distinct definitions for branch and tag but for my purposes they are the same). How do I determine what branch/tag I am on?

  • Tag suggestion (not tag autocomplete)

    - by takeshin
    AJAX autocomplete is fairly simple to implement. However, I wonder how to handle smart tag suggestion like this on SO. To clarify the difference between autocomplete and suggestion: autocomplete: foo [foobar, foobaz] suggestion: foo [barfoo, foobar, foobaz], or even better, with 'did you mean' feature: [barfoo, foobar, foobaz, fobar, fobaz] I suppose I need some full text search in tags (all letters indexed, not just words). There would be no problem to do it witch regex or other patterns for limited number of tags (even client side). But how to implement this feature for big number of tags? Is there any particular reason (besides URL) the tags on SO are dash separated? What about Unicode characters in tags? I store the tags in the table with the following columns: id, tagname. My SQL query returns objects with following fields: id, tagname, count

  • nginx not serving admin static files?

    - by toto_tico
    First, I want to clarify that this error is just for the admin static files. This means my problem is specific just to the static files that corresponds to the Django admin. The rest of the static files are working perfect. Basically my problem is that for some reason I cannot access those admin static files with the ngix server. It works perfect with the micro server of Django and the collect static is doing its job. This means it is putting the files on the expected place in the static folder. The urls are correct but I cannot even access the admin static files directly, but the others I can. So, for example, I am able to access this url (copying it in the browser): myserver.com:8080/static/css/base/base.css but i am not able to access this other url (copying it in the browser): myserver.com:8080/static/admin/css/admin.css I also tried to copy the admin/ directory structure into other_admin_directory_name/. Then I can access myserver.com:8080/static/other_admin_directory_name/css/admin.css Then, it works. So, I checked permissions and everything is fine. I tried to change ADMIN_MEDIA_PREFIX = '/static/admin/' to ADMIN_MEDIA_PREFIX = '/static/other_admin_directory_name/', it doesn't work. This a mistery in itself that I am exploring but still no luck. Finally, and it seems to be an important clue: I tried to copy the admin/ directory structure into admin_and_then_any_suffix/. Then I cannot access myserver.com:8080/static/admin_and_then_any_suffix//css/admin.css So, if the name of the directory starts with admin (for example administration or admin2) it doesn't work. * added thanks to sarnold observation ** the problem seems to be in the nginx configuration file /etc/nginx/sites-available/mysite location /static/admin { alias /home/vl3/.virtualenvs/vl3/lib/python2.7/site-packages/django/contrib/admin/media/; }

  • Celery daemon as a Ubuntu service does not consume tasks while running from terminal does

    - by Guy
    On Ubuntu 11.10, I have to issue python tasks from django using celery. I'm currently testing on the same machine but eventually the celery worker should run on a remote machine. django uses the following settings: BROKER_HOST = "127.0.0.1" BROKER_PORT = 5672 BROKER_VHOST = "/my_vhost" BROKER_USER = "celery" BROKER_PASSWORD = "celery" I can also see my task queued in http://localhost:55672/#/queues the celery daemon uses the following configuration (celeryconfig.py): BROKER_HOST = "127.0.0.1" BROKER_PORT = 5672 BROKER_USER = "celery" BROKER_PASSWORD = "celery" BROKER_VHOST = "/my_vhost" CELERY_RESULT_BACKEND = "amqp" import os import sys sys.path.append(os.getcwd()) CELERY_IMPORTS = ("tasks", ) running celeryd -l info works well and now I want to run it as a service. I've followed the instructions from http://ask.github.com/celery/cookbook/daemonizing.html and now I'm trying to run it using: sudo /etc/init.d/celeryd start But the message is not being consumed, no error in the celery log either. /etc/default/celeryd CELERYD_NODES="w1" CELERYD_CHDIR="/path/to/django/project" CELERYD_OPTS="--time-limit=300 --concurrency=1" CELERY_CONFIG_MODULE="celeryconfig" # %n will be replaced with the nodename.

CELERYD_USER="celery" CELERYD_GROUP="celery" I've also created user celery in Ubuntu not sure if its necessary. Any help will be appreciated, Thanks, Guy

  • MySQL Not Turning On

    - by Shalin Shah
    I have an amazon ec2 instance running on the Amazon Linux AMI and its a micro instance. I wanted to install Django onto my server so I entered these commands wget http://www.mlsite.net/blog/wp-content/uploads/2008/11/go wget http://www.mlsite.net/blog/wp-content/uploads/2008/11/django.conf chmod 744 go ./go So after I was done, I ran sudo service httpd restart and sudo service mysqld restart and This is what came up for mysqld: Stopping mysqld: [ OK ] MySQL Daemon failed to start. Starting mysqld: [FAILED] So I deleted the django files /usr/local/python2.6.8/site-packages/django_registration.egg and I tried finding the error and I found out that in my /etc/my.cnf for the socket, it said socket=/var/lock/subsys/mysql.sock so I went to /var/lock/subsys/ and there was no mysql.sock. I tried creating one using vim but it still didn't work. Then I checked the error log and it said Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) So I am pretty much lost right now. I know it has something to do with mysql.sock If you might know a reason why this was caused could you please let me know? I have a wordpress site on my server, so i kind of need MySQL to work. Thanks!

  • Server performance worsened after a hardware upgrade: how should I reconfigure the server?

    - by twick
    I'm running a site on an Ubuntu/Apache/Django/PostgreSQL stack. We upgraded our server recently from 1 processor with 2 Gb total RAM (with 0.5 Gb of that RAM assigned to memcached) to a new server that has 2 processors with 4 Gb total RAM (with 2 Gb of that RAM assigned to memcached). However, when I looked at Google Webmaster Tools, I found out that the average page speed has worsened from 5 seconds to 15 seconds. Why would performance get worse with a hardware upgrade? What should I check and tune? Is this more likely to be a problem with memcached, Apache, Django, or PostgreSQL?

  • Installing GeoIP on Mac?

    - by Richard
    I want to install the MaxMind GeoIP C library, so that I can use GeoIP as part of Django. I'm working on MacOS. I've downloaded GeoIP-1.4.8.tar.gz from here and run: ./configure make make check make install without any problems. I've also downloaded GeoIP.dat.gz and GeoLiteCity.dat.gz, unzipped them and put them in a local directory. Then I've set the following paths in my settings.py: GEOIP_PATH = 'path_to_dat_files' GEOIP_LIBRARY_PATH = 'path_to_c_files' Now I'm trying to run python manage.py migrate (which has a reference to GeoIP in a project I'm using), but I'm still getting this error: from django.contrib.gis.utils import GeoIP ImportError: cannot import name GeoIP Any ideas? Thanks.

  • Why would the 'show processlist' command speed up normally slow requests to my remote DB? (connected via VPN)

    - by Hakan B.
    I am running a local Django development server that connects to a remote MySQL server via a VPN (IPSec). Request times are awfully slow and I consistently see timeouts. Attempting to diagnose the problem, I logged in to the remote database and ran: show full processlist Immediately, the local server went from idle to working. The page had not yet completely loaded, but progress had been made (debug logs confirm this). When I ran 'show full processlist' several times more in succession, the request completed quickly. I can currently reproduce this - unless I run 'show full processlist' over and over on the remote server, my local request usually times out. Does anyone have any idea why this would happen? I'm running Django 1.3 and OS X 10.7. Note: I realize this may be entirely not be a question with a clear-cut answer and is probably my fault, but it is odd and reproducable, so I hope someone can at least point me the right direction. Thanks in advance.

  • One of my apache processes is huge - how can I find out why?

    - by Malcolm Box
    I'm running Apache 2.2.12 with mod_wsgi, hosting a Django site. Most of the apache child processes weigh in at about 125MB RSS, but occasionally I see one child balloon to 1GB RSS. At this point there's usually 1 huge process (1GB), a couple of large ones (500MB) and the rest are still ~125MB. These are the mod_wsgi daemon processes. I've tried using memory leak tracing in Python to see if it's the Django code, and I see no leaks. Looking in the logs doesn't show any particularly strange requests. I'm stumped on how to figure out what's causing this - any ideas? Also, any workaround ways to kill the large apache process when it gets too big, without bringing apache down? Some more details: Not using mod_php Using pre-fork
