  • Django-modpython project in a directory

    - by Ankit Jaiswal
    Hi All, I am deploying a Django project on apache server with mod_python in linux. I have created a directory structure like: /var/www/html/django/demoInstall where demoInstall is my project. In the httpd.conf I have put the following code. <Location "/django/demoInstall"> SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE demoInstall.settings PythonOption django.root django/demoInstall PythonDebug On PythonPath "['/var/www/html/django'] + sys.path" </Location> It is getting me the django environment but the issue is that the urls mentioned in urls.py are not working correctly. In my url file I have mentioned the url like: (r'^$', views.index), Now, in the browser I am putting the url like : http://domainname/django/demoInstall/ and I am expecting the views.index to be invoked. But I guess it is expecting the url to be only: http://domainname/ . When I change the url mapping to: (r'^django/demoInstall$', views.index), it works fine. Please suggest as I do not want to change all the mappings in url config file. Thanks in advance.

  • apache+mod_wsgi configuration for django project(s) on a quad core

    - by Stefano
    I've been experiment quite some time with a "typical" django setting upon nginx+apache2+mod_wsgi+memcached(+postgresql) (reading the doc and some questions on SO and SF, see comments) Since I'm still unsatisfied with the behavior (definitely because of some bad misconfiguration on my part) I would like to know what a good configuration would look like with these hypotesis: Quad-Core Xeon 2.8GHz 8 gigs memory several django projects (anything special related to this?) These are excerpts form my current confs: apache2 SetEnv VHOST null #WSGIPythonOptimize 2 <VirtualHost *:8082> ServerName subdomain.domain.com ServerAlias www.domain.com SetEnv VHOST subdomain.domain AddDefaultCharset UTF-8 ServerSignature Off LogFormat "%{X-Real-IP}i %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" custom ErrorLog /home/project1/var/logs/apache_error.log CustomLog /home/project1/var/logs/apache_access.log custom AllowEncodedSlashes On WSGIDaemonProcess subdomain.domain user=www-data group=www-data threads=25 WSGIScriptAlias / /home/project1/project/wsgi.py WSGIProcessGroup %{ENV:VHOST} </VirtualHost> wsgi.py import os import sys # setting all the right paths.... _realpath = os.path.realpath(os.path.dirname(__file__)) _public_html = os.path.normpath(os.path.join(_realpath, '../')) sys.path.append(_realpath) sys.path.append(os.path.normpath(os.path.join(_realpath, 'apps'))) sys.path.append(os.path.normpath(_public_html)) sys.path.append(os.path.normpath(os.path.join(_public_html, 'libs'))) sys.path.append(os.path.normpath(os.path.join(_public_html, 'django'))) os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' import django.core.handlers.wsgi _application = django.core.handlers.wsgi.WSGIHandler() def application(environ, start_response): """ Launches django passing over some environment (domain name) settings """ application_group = environ['mod_wsgi.application_group'] """ wsgi application group is required. It's also used to generate the HOST.DOMAIN.TLD:PORT parameters to pass over """ assert application_group fields = application_group.replace('|', '').split(':') server_name = fields[0] os.environ['WSGI_APPLICATION_GROUP'] = application_group os.environ['WSGI_SERVER_NAME'] = server_name if len(fields) > 1 : os.environ['WSGI_PORT'] = fields[1] splitted = server_name.rsplit('.', 2) assert splitted >= 2 splited.reverse() if len(splitted) > 0 : os.environ['WSGI_TLD'] = splitted[0] if len(splitted) > 1 : os.environ['WSGI_DOMAIN'] = splitted[1] if len(splitted) > 2 : os.environ['WSGI_HOST'] = splitted[2] return _application(environ, start_response)` folder structure in case it matters (slightly shortened actually) /home/www-data/projectN/var/logs /project (contains manage.py, wsgi.py, settings.py) /project/apps (all the project ups are here) /django /libs Please forgive me in advance if I overlooked something obvious. My main question is about the apache2 wsgi settings. Are those fine? Is 25 threads an /ok/ number with a quad core for one only django project? Is it still ok with several django projects on different virtual hosts? Should I specify 'process'? Any other directive which I should add? Is there anything really bad in the wsgi.py file? I've been reading about potential issues with the standard wsgi.py file, should I switch to that? Or.. should this conf just be running fine, and I should look for issues somewhere else? So, what do I mean by "unsatisfied": well, I often get quite high CPU WAIT; but what is worse, is that relatively often apache2 gets stuck. It just does not answer anymore, and has to be restarted. I have setup a monit to take care of that, but it ain't a real solution. I have been wondering if it's an issue with the database access (postgresql) under heavy load, but even if it was, why would the apache2 processes get stuck? Beside these two issues, performance is overall great. I even tried New Relic and got very good average results.

  • How to make designer generated .Net application settings portable

    - by Ville Koskinen
    Hello, I've been looking at modifying the source of the Doppler podcast aggregator with the goal of being able to run the program directly from my mp3 player. Doppler stores application settings using a Visual Studio designer generated Settings class, which by default serializes user settings to the user's home directory. I'd like to change this so that all settings would be stored in the same directory as the exe. It seems that this would be possible by creating a custom provider class which inherits the SettingsProvider class. Has anyone created such a provider and would like to share code? Update: I was able to get a custom settings provider nearly working by using this MSDN sample, i.e. with simple inheritance. I was initially confused as Windows Forms designer stopped working until I did this trick suggested at Codeproject: internal sealed partial class Settings { private MySettingsProvider settingsprovider = new MySettingsProvider(); public Settings() { foreach (SettingsProperty property in this.Properties) { property.Provider = settingsprovider; } ... The program still starts with window size 0;0 though. Anyone with any insight to this? Why the need to assing the provider in runtime---instead of using attributes as suggested by MSDN? Why the changes in how the default settings are passed to the application with the default settings provider vs. the custom one?

  • django url matching with Lighttpd fastcgi

    I have a problem with url. I can access the djando app home page ( localhost/djangotest/ ) but can't access the admin section ( localhost/djangotest/admin/ ). I can access it using the django server instead of lighttpd. Lighttp conf : fastcgi.server = ( "/djangotest/" => ( "main" => ( "host" => "127.0.0.1", "port" => 3033, "check-local" => "disable", ) ), ) url.rewrite-once = ( "^(/media.*)$" => "$1", "^/favicon\.ico$" => "/media/favicon.ico", "^/djangotest/[^?](.*)$" => "/djangotest/?$1", ) The django url.py is just : (i just uncommented the good lines) : from django.conf.urls.defaults import patterns, include, url from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), ) I tried many things but without success ...

  • Social Game Mechanics in Django

    - by oliland
    I want users to receive 'points' for completing various tasks in my application - ranging from tasks such as tagging objects to making friends. I havn't yet found a Django application that simplifies this. At the moment I'm thinking that the best way to accumulate points is that each user action creates the equivalent of a "stream item", and the points are calculated through counting the value of each action published to their stream. Obviously social game mechanics is a huge area with a lot of research going on at the moment. But from a development perspective what's the easiest way to get started? Am I on the wrong track or are there better / simpler ways?

  • Looping to provide multiple lines in linechart (django-googlecharts)

    - by mighty_bombero
    Hi, I'm trying to generate some charts using django-googlecharts. This works fine for rather static data but in one case I would like to render a different number of lines, based on a variable. I tried this: {% chart %} {% for line in line_data %} {% chart-data line %} {% endfor %} {% chart-size "390x200" %} {% chart-type "line" %} {% chart-labels days %} {% endchart %} Line data is a list containing lists. The template code fails with "Caught an exception while rendering: max() arg is an empty sequence". I guess the problem is that I try to loop over templatetags. What approach could be used here? Or am I completely missing something? Is this doable using inclusion tags? Thanks for your help.

  • Django data migration when changing a field to ManyToMany

    - by Ken H
    I have a Django application in which I want to change a field from a ForeignKey to a ManyToManyField. I want to preserve my old data. What is the simplest/best process to follow for this? If it matters, I use sqlite3 as my database back-end. If my summary of the problem isn't clear, here is an example. Say I have two models: class Author(models.Model): author = models.CharField(max_length=100) class Book(models.Model): author = models.ForeignKey(Author) title = models.CharField(max_length=100) Say I have a lot of data in my database. Now, I want to change the Book model as follows: class Book(models.Model): author = models.ManyToManyField(Author) title = models.CharField(max_length=100) I don't want to "lose" all my prior data. What is the best/simplest way to accomplish this? Ken

  • django __search - trying to do x+y__search

    - by ckohrman
    I'm trying to do something like this with django: Q(x+y__search = z) I'm using __search to boolean search for a list of words within two separate lists (requiredTags, preferredTags). Line 10 is the one I have questions about. I want to see if the list of words (requTags) is found among requiredTags or preferredTags. requTags="" prefeTags="" for i in reqTags: if(i!=""): requTags+="+"+i+" " for i in prefTags: if(i!=""): prefeTags+=i+" " if(requTags!=""): query=query &( Q(requiredTags__search + preferredTags__search = requTags)) if(prefeTags!=""): query=query &( Q(requiredTags__search = prefeTags) | Q(preferredTags__search = prefeTags)) For instance: requTags might be: +beans +rice +cheese. requiredTags might be: beans,rice,tortilla preferredTags might be: cheese I didn't see any way to combine requiredTags and preferredTags in the documentation. Any help would be appreciated as I'm a beginner...

  • Django-pyodbc SQL Server/freetds server connection problems on linux

    - by wizard
    Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnectW)') I'm migrating from developing on a windows development machine to Linux machine in production and I'm having issues with the freetds driver. As far as I can tell that error message means it can't find the driver. I can connect via the cli via sqsh and tsql. I've setup my settings.py as such. 'bc2db': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'DataTEST', 'USER': 'appuser', 'PASSWORD': 'PASS', 'HOST': 'bc2.domain.com', 'options': { 'driver': 'FreeTDS', } }, Does anyone have any SQL Server experience with django? do I have to use a dns? (how would I format that?)

  • iPhone Settings app and keyboard control?

    - by randallmeadows
    So I'm putting my app's preference settings into the Settings app. One of the settings is an edit text field (PSTextFieldSpecifier). When touched, the keyboard dutifully appears, I can make the edits, but when I press Return....nothing. Well, the editing is completed, but the keyboard remains. I see no way to make the keyboard go away. I also notice this same behavior in other Settings panes, including those from Apple. Do I assume correctly that this is just standard behavior and I need to just accept the fact that my Settings table has now been reduced to half size, and just deal? Furthermore, I gather there is no approved way to have a "rich" child pane display, such as that seen in Settings-General-About-Legal? Or a way to do what appears to be a -presentModalViewController, a la Settings-General-Passcode Lock?

  • Python's Django or Delphi's IntraWeb?

    - by Azad Salahli
    Well, forgive me if it is an off-topic question. I have no knowledge about web programming, so I apologize in advance, if it is a stupid question. I will start to build a web based application. To be more specific, I will make a webpage which will have components like buttons, textboxes and etc. It will use a database to store information. My question is, which one is better to learn for that purpose? Python's Django or Delphi's IntraWeb? I know both Delphi and Python(although I know Delphi better).

  • Automatically create an admin user when running Django's ./manage.py syncdb

    - by a paid nerd
    My project is in early development. I frequently delete the database and run manage.py syncdb to set up my app from scratch. Unfortunately, this always pops up: You just installed Django's auth system, which means you don't have any superusers defined. Would you like to create one now? (yes/no): Then you have supply a username, valid email adress and password. This is tedious. I'm getting tired of typing test\[email protected]\ntest\ntest\n. How can I automatically skip this step and create a user programatically when running manage.py syncdb ?

I am outputting them to the template like this: <ul> {% for message in messages %} <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li> {% endfor %} </ul> This outputs all the messages, errors, warning, success etc. I was just wondering if anyone had any ideas how to display only the error messages something like: <ul> {% for message in messages.errors %} <li>{{ message }}</li> {% endfor %} </ul> Any ideas? Thanks in advance.

  • Tips/Process for web-development using Django in a small team

    - by Mridang Agarwalla
    We're developing a web app uing Django and we're a small team of 3-4 programmers — some doing the UI stuff and some doing the Backend stuff. I'd love some tips and suggestions from the people here. This is out current setup: We're using Git as as our SCM tool and following this branching model. We're following the PEP8 for your style guide. Agile is our software development methodology and we're using Jira for that. We're using the Confluence plugin for Jira for documentation and I'm going to be writing a script that also dumps the PyDocs into Confluence. We're using virtualenv for sandboxing We're using zc.buildout for building This is whatever I can think of off the top of my head. Any other suggestions/tips would be welcome. I feel that we have a pretty good set up but I'm also confident that we could do more. Thanks.

  • Using multilingual and localeurl in django

    - by Dmitry A. Erokhin
    Using dajngo-multilingual and localeurl. Small sample of my main page view: def main(request): #View for http://www.mysite.com/ name = Dog.objects.all()[0].full_name #this is a translated field return render_to_response("home.html", {"name" : name}) Entering http://www.mysite.com/ redirects me to http://www.mysite.com/ru/ and "name" variable gets russian localization. For now it's ok... But... Entering http://www.mysite.com/en/ shows me same russian loclized variable. During my experiments with debuger I've discovered: request.LANGUAGE_CODE is changing properly according to /en/ or /ru/ url suffix (thanx to localeurl) invoking multilingual.languages.set_default_language() makes "name" variable change loclization The question is: should I change language of django-multilingual to request.LANGUAGE_CODE in each of my view myself, or it must be solved automaticly and I've done something wrong?

  • Accidentally uninstalled Ubuntu 14.04 system settings. How to get them back?

    - by Dan
    Somehow, cleaning up useless software (using software center), I uninstalled Ubuntu "system settings". I did this by mistake. Now I fail to find system settings application using software center (and there are so many items in history...). It seems strange to me because usually when I try to uninstall something critical (system testing for example), the dependencies manager tells me It will uninstall the whole desktop system then. I am sure I did not have that warning. So I need the name of the software to install or a command line command rather than a system restore to get it back. Very interesting thing. If you ever want to play with this and reproduce it, you will be confused to see Ubuntu Mobile system settings instead! Yes, mobile network and touchscreen settings! Happy pre-release viewing!

  • Django comparing model instances for equality

    - by orokusaki
    I understand that, with a singleton situation, you can perform such an operation as: spam == eggs and if spam and eggs are instances of the same class with all the same attribute values, it will return True. In a Django model, this is natural because two separate instances of a model won't ever be the same unless they have the same .pk value. The problem with this is that if a reference to an instance has attributes that have been updated by middleware somewhere along the way and it hasn't been saved, and you're trying to it to another variable holding a reference to an instance of the same model, it will return False of course because they have different values for some of the attributes. Obviously I don't need something like a singleton , but I'm wondering if there some official Djangonic (ha, a new word) method for checking this, or if I should simply check that the .pk value is the same with: spam.pk == eggs.pk I'm sorry if this was a huge waste of time, but it just seems like there might be a method for doing this, and something I'm missing that I'll regret down the road if I don't find it.

  • Use variable as dictionary key in Django template

    I'd like to use a variable as an key in a dictionary in a Django template. I can't for the life of me figure out how to do it. If I have a product with a name or ID field, and ratings dictionary with indices of the product IDs, I'd like to be able to say: {% for product in product_list %} <h1>{{ ratings.product.id }}</h1> {% endfor %} In python this would be accomplished with a simple ratings[product.id] But I can't make it work in the templates. I've tried using with... no dice. Ideas?
