  • class browsing in django

    - by jamida
    I'd like to browse active classes in Django. I think I'd learn a lot that way. So what's a good way to do that? I could use IDLE if I knew how to start Django from within IDLE. But as I'm new to Python/Django, I'm not particularly wedded to IDLE. Other alternatives?

  • Replicating multicolumn lists from the Django admin CSS

    - by mfalcon
    Hi, I'm developing a Django project and I've to show a multicolumn list for the different objects of a table. I like the design of the django-admin for showing list-objects so I looked at the code to see how it works. As I am a CSS begginer the code seemed a bit difficult and extensive to comprehend. Is there a simplier way to make what I want or actually the CSS code of the django-admin is the path to follow?

  • Use only some parts of Django?

    - by Hanno Fietz
    I like Django, but for a particular application I would like to use only parts of it, but I'm not familiar enough with how Django works on the inside, so maybe someone can point me into the right direction as to what I have to check out. Specifically, I want to use: The models and database abstraction The caching API, although I want to avoid database lookups by caching, not HTML generation, and since the caching framework in Django is intended for the latter, I'm not sure yet whether that's really appropriate. I would not use: Templating urlconfigs Or, more exactly, I'm neither using HTTP nor HTML. So basically, I have a different input / output chain than usual. Can this work? My personal killer feature in Django is the Object / database mapping that I can do with the models, so if there's another technology (doesn't have to be Python, I'm in the design phase and I'm pretty agnostic about languages and platforms) that gives me the same abilities, that would be great, too.

  • Django Encoding Issues with MySQL

    - by Jordan Reiter
    Okay, so I have a MySQL database set up. Most of the tables are latin1 and Django handles them fine. But, some of them are UTF-8 and Django does not handle them. Here's a sample table (these tables are all from django-geonames): DROP TABLE IF EXISTS `geoname`; SET @saved_cs_client = @@character_set_client; SET character_set_client = utf8; CREATE TABLE `geoname` ( `id` int(11) NOT NULL, `name` varchar(200) NOT NULL, `ascii_name` varchar(200) NOT NULL, `latitude` decimal(20,17) NOT NULL, `longitude` decimal(20,17) NOT NULL, `point` point default NULL, `fclass` varchar(1) NOT NULL, `fcode` varchar(7) NOT NULL, `country_id` varchar(2) NOT NULL, `cc2` varchar(60) NOT NULL, `admin1_id` int(11) default NULL, `admin2_id` int(11) default NULL, `admin3_id` int(11) default NULL, `admin4_id` int(11) default NULL, `population` int(11) NOT NULL, `elevation` int(11) NOT NULL, `gtopo30` int(11) NOT NULL, `timezone_id` int(11) default NULL, `moddate` date NOT NULL, PRIMARY KEY (`id`), KEY `country_id_refs_iso_alpha2_e2614807` (`country_id`), KEY `admin1_id_refs_id_a28cd057` (`admin1_id`), KEY `admin2_id_refs_id_4f9a0f7e` (`admin2_id`), KEY `admin3_id_refs_id_f8a5e181` (`admin3_id`), KEY `admin4_id_refs_id_9cc00ec8` (`admin4_id`), KEY `fcode_refs_code_977fe2ec` (`fcode`), KEY `timezone_id_refs_id_5b46c585` (`timezone_id`), KEY `geoname_52094d6e` (`name`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; SET character_set_client = @saved_cs_client; Now, if I try to get data from the table directly using MySQLdb and a cursor, I get the text with the proper encoding: >>> import MySQLdb >>> from django.conf import settings >>> >>> conn = MySQLdb.connect (host = "localhost", ... user = settings.DATABASES['default']['USER'], ... passwd = settings.DATABASES['default']['PASSWORD'], ... db = settings.DATABASES['default']['NAME']) >>> cursor = conn.cursor () >>> cursor.execute("select name from geoname where name like 'Uni%Hidalgo'"); 1L >>> g = cursor.fetchone() >>> g[0] 'Uni\xc3\xb3n Hidalgo' >>> print g[0] Unión Hidalgo However, if I try to use the Geoname model (which is actually a django.contrib.gis.db.models.Model), it fails: >>> from geonames.models import Geoname >>> g = Geoname.objects.get(name__istartswith='Uni',name__icontains='Hidalgo') >>> g.name u'Uni\xc3\xb3n Hidalgo' >>> print g.name Unión Hidalgo There's pretty clearly an encoding error here. In both cases the database is returning 'Uni\xc3\xb3n Hidalgo' but Django is (incorrectly?) translating the '\xc3\xb3n' to ó. What can I do to fix this?

  • Django + WebKit = Broken pipe

    - by Saosin
    I'm running the Django 1.2 development server and I get these Broken Pipe error messages whenever I load a page from it with Chrome or Safari. My co-worker is getting the error as well when he loads a page from his dev server. We don't have these errors when using Opera or Firefox.

  • How to set up django-admin.py on windos vista?

    - by shin
    I manage to install Django after some struggles by using setup.py install on Windows Vista Now I tried to use django-admin.py but it is not working. According to this document, http://docs.djangoproject.com/en/dev/ref/django-admin/ The django-admin.py script should be on your system path if you installed Django via its setup.py utility. If it’s not on your path, ... For Windows users, who do not have symlinking functionality available, you can copy django-admin.py to a location on your existing path or edit the PATH settings (under Settings - Control Panel - System - Advanced - Environment...) to point to its installed location. I checked ComputerpropertiesEnvironment Variables, but path to django-admin.py is not in anywhere. So I added C:\Python25\Lib\site-packages\django\bin which is the folder of django-admin.py in User variables for shin Variable PATH, Value C:\Program Files\Google\google_appengine\;C:\Python25\Lib\site-packages\django\bin\ Am I supposed to add to System variables?? But it still does not work. Could anyone tell me how to add the Path in Environment Variables please? Thanks in advance.

  • Django Comments and Users integration

    - by Patrick
    Hi folks, I am new to django. I am trying to use django.contrib.comments, I saw the table in the database like this, but how can I integrate it with user_id, user_photos, user_name, user_email....and those things with the django commenting system? I also tried to use thread-comments, but I can't configure it properly, is the django threadedcomments table similar to following ? Please let me know if any of you have done this before....all I need is a user login, and post comments, and then show list of comments with users' profile photos and username, as well as there comments.

  • Ditching Django's models for Ajax/Web Services

    - by Igor Ganapolsky
    Recently I came across a problem at work that made me rethink Django's models. The app I am developing resides on a Linux server. Its a simple model/view/controller app that involves user interaction and updating data in the database. The problem is that this data resides in a MS SQL database on a Windows machine. So in order to use Django's models, I would have to leverage an ODBC driver on linux, and the use a python add-on like pyodbc. Well, let me tell you, setting up a reliable and functional ODBC connection on linux is no easy feat! So much so, that I spent several hours maneuvering this on my CentOS with no luck, and was left with frustration and lots of dumb system errors. In the meantime I have a deadline to meet, and suddenly the very agile and rapid Django application is a roadblock rather than a pleasure to work with. Someone on my team suggested writing this app in .NET. But there are a few problems with that: it won't be deployable on a linux machine, and I won't be able to work on it since I don't know ASP.net. Then a much better suggestion was made: keep the app in django, but instead of using models, do straight up ajax/web services calls in the template. And then it dawned on me - what a great idea. Django's models seem like a nuissance and hindrance in this case, and I can just have someone else write .Net services on their side, that I can call from my template. As a result my app will be leaner and more compact. So, I was wondering if you guys ever came across a similar dillema and what you decided to do about it.

  • django development IDE

    - by Adam Carr
    I have done a little django development but it has all been in a text editor. I was curious what more advanced development tools others are using in their django development. I am used to using Visual Studio for development and really like the intellisense, code completion, and file organization it provides and would like to find something (or a combination of tools) that would provide some of this in the django/python environment.

  • Django: Paginator + raw SQL query

    - by Silver Light
    Hello! I'm using Django Paginator everywhere on my website and even wrote a special template tag, to make it more convenient. But now I got to a state, where I need to make a complex custom raw SQL query, that without a LIMIT will return about 100K records. How can I use Django Pagintor with custom query? Simplified example of my problem: My model: class PersonManager(models.Manager): def complicated_list(self): from django.db import connection #Real query is much more complex cursor.execute("""SELECT * FROM `myapp_person`"""); result_list = [] for row in cursor.fetchall(): result_list.append(row[0]); return result_list class Person(models.Model): name = models.CharField(max_length=255); surname = models.CharField(max_length=255); age = models.IntegerField(); objects = PersonManager(); The way I use pagintation with Django ORM: all_objects = Person.objects.all(); paginator = Paginator(all_objects, 10); try: page = int(request.GET.get('page', '1')) except ValueError: page = 1 try: persons = paginator.page(page) except (EmptyPage, InvalidPage): persons = paginator.page(paginator.num_pages) This way, Django get very smart, and adds LIMIT to a query when executing it. But when I use custom manager: all_objects = Person.objects.complicated_list(); all data is selected, and only then python list is sliced, which is VERY slow. How can I make my custom manager behave similar like built in one?

  • Ajax foreign key filter in Django admin interface

    - by Googol
    http://blog.philippmetzler.com/?p=52 Just tried django-ajax-filtered-fields and like it very much. I’m looking for a solution for this problem: My model looks like this: class Song(models.Model): Album = models.ForeignKey(Album) class Artist(models.Model): album = models.ForeignKey(Album) song = models.ForeignKey(Song, blank=True, null=True) So the user has to define a topic. He can also define a subtopic but doesn’t have to. The subtopic belongs to a topic. In the admin interface I’d like to limit the choices for subtopic based upon what he selects in topics. That should change dynamically with AJAX. I will have a closer look to django-ajax-filtered-fields but didn’t find a solution to that specific problem. Perhaps it’s another usecase for django-ajax-filtered-fields in general? Or do you know another solution to my specific requirements?

    I followed the instructions here: https://www.windowsazure.com/en-us/develop/python/tutorials/django-with-visual-studio/ However, whenever I try to open the url to my web app in the cloud I get a 500 error. The tutorial doesn't mention setting up the TEMPLATE_DIRS setting in the django application or doing any work on the cloud service machine to install python/django. Could these be the problem?

  • Django 1.2 crash course needed

    - by delusionalweekendwarrior
    I know Python but I've never used Django. What do I need to know about Django 1.2 to port my typical PHP CRUD web application in one weekend? (Yes I've read Joel Spolsky's Netscape article :-)) I'm reading this tutorial right now and it's excellent. I'm already playing around with inspectdb to generate my models from the existing schema. I'm planning to use the following features of Django this weekend: Fragment caching Static asset versioning (for far future expires) Schema migrations (or whatever they're called in Django) Auto-admin (and customize it later) The test framework ...other stuff I probably don't know about yet I'm familiar with all these concepts in other languages/frameworks, except for the ORM which I've never used. I know SQL pretty well though. Any links, sage bits of advice, gotchas, stuff not mentioned in the (excellent) tutorial/docs, or stuff that is mentioned but warrants repeating == very welcome. Thanks!

  • Get the path to Django itself

    - by andybak
    I've got some code that runs on every (nearly) every admin request but doesn't have access to the 'request' object. I need to find the path to Django installation. I could do: import django django_path = django.__file__ but that seems rather wasteful in the middle of a request. Does putting the import at the start of the module waste memory? I'm fairly sure I'm missing an obvious trick here.

  • Django-admin.py not being recognized suddenly

    - by Jen Camara
    I tried starting a new Django project yesterday but when I did "django-admin.py startproject projectname" I got an error stating: "django-admin.py is not recognized as an internal or external command." The strange thing is, when I first installed Django, I made a few projects and everything worked fine. But now after going back a few months later it has suddenly stopped working. I've tried looking around for an answer and all I could find is that this typically has to do with the system path settings, however, I know that I have the proper paths set up so I don't understand what's happening. Does anybody have any idea what's going on?

  • FastCGI has to be restarted for new content to be displayed on my Django site

    - by vorpyg
    I'm currently testing serving my Django site with Nginx, FastCGI and Flup. The server is configured roughly as described in the Django Advent article. I had to do some minor modifications in order to make it work in Ubuntu 9.10. The problem is that when I add new content it doesn't show up on the page before I restart the FastCGI process. I haven't enabled any caching functionality in Django, and when I query the DB from the Django shell it works as expected. Anybody got ideas to what's causing this?

  • Problems with i18n using django translation on App-Engine with Korean and Hindi

    - by Greg
    I've got a setup based on the post here, and it works perfectly. Adding more languages to the mix, it recognises them fine, except for Korean (ko) and Hindi (hi). Chinese/Japanese/Hebrew are all fine, so nothing to do with encodings/charsets I don't think. Taking a look into the django code inside the app-engine SDK, I notice that all the languages that I'm using except for ko and hi are ones that ship with django - in the default settings.py and inside the locale folder they are missing. If I copy one of the locale folders inside the /usr/local/google_appengine/lib/django[...]/conf/locale and rename it to be 'ko', then it starts working in my app, but I won't be able to replicate this modification when I deploy to app-engine, so need a bit of help understanding what I might be doing wrong. my settings.py is definitely being taken into account, as if I remove languages from there then they stop working (as they should). If I copied the django modules into my app, under 'lib' there say, could I use those instead of the ones app-engine tries to use, maybe? I'm brand new to python/django/app-engine, and developing on a Mac with Leopard, if that makes any difference. I have the latest app-engine SDK as of tuesday.
