• Default value for field in Django model

  - by Daniel Garcia

  Suppose I have a model: class SomeModel(models.Model): id = models.AutoField(primary_key=True) a = models.IntegerField(max_length=10) b = models.CharField(max_length=7) Currently I am using the default admin to create/edit objects of this type.

• How to manually render a Django template for an inlineformset_factory with can_delete = True / False

  - by chefsmart

  I have an inlineformset with a custom Modelform. So it looks something like this: MyInlineFormSet = inlineformset_factory(MyMainModel, MyInlineModel, form=MyCustomInlineModelForm) I am rendering this inlineformset manually in a template so that I have more control over widgets and javascript. So I go in a loop like {% for form in myformset.forms %} and then manually render each field as described on this page http://docs.djangoproject.com/en/dev/topics/forms/#customizing-the-form-template The formset has can_delete = True or can_delete = False depending on whether the user is creating new objects or editing existing ones. Question is, how do I manually render the can_delete checkbox?

• Upload Image with Django Model Form

  - by jmitchel3

  I'm having difficulty uploading the following model with model form. I can upload fine in the admin but that's not all that useful for a project that limits admin access. #Models.py class Profile(models.Model): name = models.CharField(max_length=128) user = models.ForeignKey(User) profile_pic = models.ImageField(upload_to='img/profile/%Y/%m/') #views.py def create_profile(request): try: profile = Profile.objects.get(user=request.user) except: pass form = CreateProfileForm(request.POST or None, instance=profile) if form.is_valid(): new = form.save(commit=False) new.user = request.user new.save() return render_to_response('profile.html', locals(), context_instance=RequestContext(request)) #Profile.html <form enctype="multipart/form-data" method="post">{% csrf_token %} <tr><td>{{ form.as_p }}</td></tr> <tr><td><button type="submit" class="btn">Submit</button></td></tr> </form> Note: All the other data in the form saves perfectly well, the photo does not upload at all. Thank you for your help!

• Select a subset of foreign key elements in inlineformset_factory in Django

  - by Enis Afgan

  Hello, I have a model with two foreign keys: class Model1(models.Model): model_a = models.ForeignKey(ModelA) model_b = models.ForeignKey(ModelB) value = models.IntegerField() Then, I create an inline formset class, like so: an_inline_formset = inlineformset_factory(ModelA, Model1, fk_name="model_a") and then instantiate it, like so: a_formset = an_inline_formset(request.POST, instance=model_A_object) Once this formset gets rendered in a template/page, there is ChoiceField associated with the model_b field. The problem I'm having is that the elements in the resulting drop down menu include all of the elements found in ModelB table. I need to select a subset of those based on some criteria from ModelB. At the same time, I need to keep the reference to the instance of model_A_object when instantiating inlineformset_factory and, therefore, I can't just use this example. Any suggestions?

  what Im looking to do is to have a link on the name of a field of a model. So when im filling the form using the admin interface i can access some information.

• Multiple model forms with some pre-populated fields

  - by jimbocooper

  Hi! Hope somebody can help me, since I've been stuck for a while with this... I switched to another task, but now back to the fight I still can't figure out how to come out from the black hole xD The thing is as follows: Let's say I've got a product model, and then a set of Clients which have rights to submit data for the products they've been subscribed (Many to Many from Client to Product). Whenever my client is going to submit data, I need to create as many forms as products he's subscribed, and pre-populate each one of them with the "product" field as long as perform a quite simple validation (some optional fields have to be completed if it's client's first submission). I would like one form "step" for each product submission, so I've tried formWizards... but the problem is you can't pre-assign values to the forms... this can be solved afterwards when submitting, though... but not the problem that it doesn't allow validation either, so at the end of each step I can check some data before rendering next step. Then I've tried model formsets, but then there's no way to pre-populate the needed fields. I came across some django plugins, but I'm not confident yet if any of them will make it.... Did anybody has a similar problem so he can give me a ray of light? Thanks a lot in advance!! :) edit: The code I used in the formsets way is as follows: prods = Products.objects.filter(Q(start_date__lte=today) & Q(end_date__gte=today), requester=client) num = len(prods) PriceSubmissionFormSet = modelformset_factory(PriceSubmission, extra=num) formset = PriceSubmissionFormSet(queryset=PriceSubmission.objects.none())

• Getting client denied when accessing a wsgi graphite script

  - by Dr BDO Adams

  I'm trying to set up graphite on my Mac OS X 10.7 lion, i've set up apache to call the python graphite script via WSGI, but when i try to access it, i get a forbiden from apache and in the error log. "client denied by server configuration: /opt/graphite/webapp/graphite.wsgi" I've checked that the scripts location is allowed in httpd.conf, and the permissions of the file, but they seem correct.

• Configuring wsgi for a simple Python based site

  - by jbbarnes

  I have an Ubuntu 10.04 server that already has apache and wsgi working. I also have a python script that works just fine using the make_server command: if __name__ == '__main__': from wsgiref.simple_server import make_server srv = make_server('', 8080, display_status) srv.serve_forever() Now I would like to have the page always active without having to run the script manually. I looked at what Moin is doing. I found these lines in apache2.conf: WSGIScriptAlias /wiki /usr/local/share/moin/moin.wsgi WSGIDaemonProcess moin user=www-data group=www-data processes=5 threads=10 maximum-requests=1000 umask=0007 WSGIProcessGroup moin And moin.wsgi is as listed: import sys, os sys.path.insert(0, '/usr/local/share/moin') from MoinMoin.web.serving import make_application application = make_application(shared=True) QUESTION: Can I create a similar section in apache2.conf pointing to another wsgi file? Like this: WSGIScriptAlias /status /mypath/status.wsgi WSGIDaemonProcess status user=www-data group=www-data processes=5 threads=10 maximum-requests=1000 umask=0007 WSGIProcessGroup status And if so, what is required to convert my simple_server script into a daemonized process? Most of the information I find about wsgi is related to using it with frameworks like Django. I haven't found a simple howto detailing how to make this work. Thanks.

• Django: What's an awesome plugin to maintain images in the admin?

  - by meder

  I have an articles entry model and I have an excerpt and description field. If a user wants to post an image then I have a separate ImageField which has the default standard file browser. I've tried using django-filebrowser but I don't like the fact that it requires django-grappelli nor do I necessarily want a flash upload utility - can anyone recommend a tool where I can manage image uploads, and basically replace the file browse provided by django with an imagepicking browser? In the future I'd probably want it to handle image resizing and specify default image sizes for certain article types. Edit: I'm trying out adminfiles now but I'm having issues installing it. I grabbed it and added it to my python path, added it to INSTALLED_APPS, created the databases for it, uploaded an image. I followed the instructions to modify my Model to specify adminfiles_fields and registered but it's not applying in my admin, here's my admin.py for articles: from django.contrib import admin from django import forms from articles.models import Category, Entry from tinymce.widgets import TinyMCE from adminfiles.admin import FilePickerAdmin class EntryForm( forms.ModelForm ): class Media: js = ['/media/tinymce/tiny_mce.js', '/media/tinymce/load.js']#, '/media/admin/filebrowser/js/TinyMCEAdmin.js'] class Meta: model = Entry class CategoryAdmin(admin.ModelAdmin): prepopulated_fields = { 'slug': ['title'] } class EntryAdmin( FilePickerAdmin ): adminfiles_fields = ('excerpt',) prepopulated_fields = { 'slug': ['title'] } form = EntryForm admin.site.register( Category, CategoryAdmin ) admin.site.register( Entry, EntryAdmin ) Here's my Entry model: class Entry( models.Model ): LIVE_STATUS = 1 DRAFT_STATUS = 2 HIDDEN_STATUS = 3 STATUS_CHOICES = ( ( LIVE_STATUS, 'Live' ), ( DRAFT_STATUS, 'Draft' ), ( HIDDEN_STATUS, 'Hidden' ), ) status = models.IntegerField( choices=STATUS_CHOICES, default=LIVE_STATUS ) tags = TagField() categories = models.ManyToManyField( Category ) title = models.CharField( max_length=250 ) excerpt = models.TextField( blank=True ) excerpt_html = models.TextField(editable=False, blank=True) body_html = models.TextField( editable=False, blank=True ) article_image = models.ImageField(blank=True, upload_to='upload') body = models.TextField() enable_comments = models.BooleanField(default=True) pub_date = models.DateTimeField(default=datetime.datetime.now) slug = models.SlugField(unique_for_date='pub_date') author = models.ForeignKey(User) featured = models.BooleanField(default=False) def save( self, force_insert=False, force_update= False): self.body_html = markdown(self.body) if self.excerpt: self.excerpt_html = markdown( self.excerpt ) super( Entry, self ).save( force_insert, force_update ) class Meta: ordering = ['-pub_date'] verbose_name_plural = "Entries" def __unicode__(self): return self.title Edit #2: To clarify I did move the media files to my media path and they are indeed rendering the image area, I can upload fine, the <<<image>>> tag is inserted into my editable MarkItUp w/ Markdown area but it isn't rendering in the MarkItUp preview - perhaps I just need to apply the |upload_tags into that preview. I'll try adding it to my template which posts the article as well.

• Problem with messages framework in Django 1.2

  Hello! I'm running Django 1.2 beta and trying out the new feature: message framework. http://docs.djangoproject.com/en/dev/ref/contrib/messages/ Everything seems to work, but when I try to output the messages, I get nothing. Seems that messages variable is empty. I double checked all the settings, they seem to be just like in the manual.

• Apache, Nginx, WSGI, django cookies get lost.

  - by Jack M.

  I'm running into a problem trying to get a Django application running in my staging environment. I'm running nginx as a reverse proxy with Apache 2.2/mod_wsgi as the target, and my Django app behind that. The problem is that the cookies are getting lost somewhere between nginx and Apache. My nginx.conf (ripped out a few locations to keep it small): http { gzip on; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass_header Set-Cookie; upstream django { server 127.0.0.1:8080; } server { listen 80; server_name encendio.iigins.com; location / { proxy_pass http://django; } } } My Apache vhosts file: <VirtualHost *:8080> ServerName encendio.test.com ServerAdmin [email protected] DocumentRoot "/usr/local/www/apache22/data" WSGIScriptAlias / /usr/local/www/apache22/data/sasquatch/wsgi_handler.py </VirtualHost> If I directly to http://encendio.test.com:8080/ the cookies work and I can log into the admin area. If I log into http://encendio.test.com/, the admin area tells me my browser isn't using cookies. Now things get kind of weird. I went so far as to look at the environ being passed into my wsgi_handler.py: _application = django.core.handlers.wsgi.WSGIHandler() def application(environ, start_response): print >> sys.stderr, environ.get('HTTP_COOKIE', "No Cookie") return _application(environ, start_response) It shows the cookie existing in the environment: [Mon Mar 22 12:15:50 2010] [error] csrftoken=9f2569elkj67984242f0e7a6dea0b791; sessionid=4e5432hjkds8603f26d5ffa02b10cd27 And this cookie matches up with what I see in nginx's log if I plug in $http_cookie on the end of the log. So Apache is getting the cookie in some form, but it's not ending up where Django can see it. I'm at my wit's end for why this isn't working, so any help is greatly appreciated. Ninja Edit: I forgot to mention that Firefox is seeing the cookies. The oddity is that every time I attempt to log in, I get a new sessionid.

• How to resolve user registration and activation email error in Django registration?

  So I was just trying to setup a basic user authentication in Django and downloaded a django registration app with templates.

• Can Django admin handle a one-to-many relationship via related_name?

  - by Mat

  The Django admin happily supports many-to-one and many-to-many relationships through an HTML <SELECT> form field, allowing selection of one or many options respectively. There's even a nice Javascript filter_horizontal widget to help. I'm trying to do the same from the one-to-many side through related_name. I don't see how it's much different from many-to-many as far as displaying it in the form is concerned, I just need a multi-select SELECT list. But I cannot simply add the related_name value to my ModelAdmin-derived field list. Does Django support one-to-many fields in this way? My Django model something like this (contrived to simplify the example): class Person(models.Model): ... manager = models.ForeignKey('self', related_name='staff', null=True, blank=True, ) From the Person admin page, I can easily get a <SELECT> list showing all possible staff to choose this person's manager from. I also want to display a multiple-selection <SELECT> list of all the manager's staff. I don't want to use inlines, as I don't want to edit the subordinates details; I do want to be able to add/remove people from the list. (I'm trying to use django-ajax-selects to replace the SELECT widget, but that's by-the-by.)

• Django - no module named app

  - by Koran

  Hi, I have been trying to get an application written in django working - but it is not working at all. I have been working on for some time too - and it is working on dev-server perfectly. But I am unable to put in the production env (apahce). My project name is apstat and the app name is basic. I try to access it as following Blockquote http://hostname/apstat But it shows the following error: MOD_PYTHON ERROR ProcessId: 6002 Interpreter: 'domU-12-31-39-06-DD-F4.compute-1.internal' ServerName: 'domU-12-31-39-06-DD-F4.compute-1.internal' DocumentRoot: '/home/ubuntu/server/' URI: '/apstat/' Location: '/apstat' Directory: None Filename: '/home/ubuntu/server/apstat/' PathInfo: '' Phase: 'PythonHandler' Handler: 'django.core.handlers.modpython' Traceback (most recent call last): File "/usr/lib/python2.6/dist-packages/mod_python/importer.py", line 1537, in HandlerDispatch default=default_handler, arg=req, silent=hlist.silent) File "/usr/lib/python2.6/dist-packages/mod_python/importer.py", line 1229, in _process_target result = _execute_target(config, req, object, arg) File "/usr/lib/python2.6/dist-packages/mod_python/importer.py", line 1128, in _execute_target result = object(arg) File "/usr/lib/pymodules/python2.6/django/core/handlers/modpython.py", line 228, in handler return ModPythonHandler()(req) File "/usr/lib/pymodules/python2.6/django/core/handlers/modpython.py", line 201, in __call__ response = self.get_response(request) File "/usr/lib/pymodules/python2.6/django/core/handlers/base.py", line 134, in get_response return self.handle_uncaught_exception(request, resolver, exc_info) File "/usr/lib/pymodules/python2.6/django/core/handlers/base.py", line 154, in handle_uncaught_exception return debug.technical_500_response(request, *exc_info) File "/usr/lib/pymodules/python2.6/django/views/debug.py", line 40, in technical_500_response html = reporter.get_traceback_html() File "/usr/lib/pymodules/python2.6/django/views/debug.py", line 114, in get_traceback_html return t.render(c) File "/usr/lib/pymodules/python2.6/django/template/__init__.py", line 178, in render return self.nodelist.render(context) File "/usr/lib/pymodules/python2.6/django/template/__init__.py", line 779, in render bits.append(self.render_node(node, context)) File "/usr/lib/pymodules/python2.6/django/template/debug.py", line 81, in render_node raise wrapped TemplateSyntaxError: Caught an exception while rendering: No module named basic Original Traceback (most recent call last): File "/usr/lib/pymodules/python2.6/django/template/debug.py", line 71, in render_node result = node.render(context) File "/usr/lib/pymodules/python2.6/django/template/debug.py", line 87, in render output = force_unicode(self.filter_expression.resolve(context)) File "/usr/lib/pymodules/python2.6/django/template/__init__.py", line 572, in resolve new_obj = func(obj, *arg_vals) File "/usr/lib/pymodules/python2.6/django/template/defaultfilters.py", line 687, in date return format(value, arg) File "/usr/lib/pymodules/python2.6/django/utils/dateformat.py", line 269, in format return df.format(format_string) File "/usr/lib/pymodules/python2.6/django/utils/dateformat.py", line 30, in format pieces.append(force_unicode(getattr(self, piece)())) File "/usr/lib/pymodules/python2.6/django/utils/dateformat.py", line 175, in r return self.format('D, j M Y H:i:s O') File "/usr/lib/pymodules/python2.6/django/utils/dateformat.py", line 30, in format pieces.append(force_unicode(getattr(self, piece)())) File "/usr/lib/pymodules/python2.6/django/utils/encoding.py", line 71, in force_unicode s = unicode(s) File "/usr/lib/pymodules/python2.6/django/utils/functional.py", line 201, in __unicode_cast return self.__func(*self.__args, **self.__kw) File "/usr/lib/pymodules/python2.6/django/utils/translation/__init__.py", line 62, in ugettext return real_ugettext(message) File "/usr/lib/pymodules/python2.6/django/utils/translation/trans_real.py", line 286, in ugettext return do_translate(message, 'ugettext') File "/usr/lib/pymodules/python2.6/django/utils/translation/trans_real.py", line 276, in do_translate _default = translation(settings.LANGUAGE_CODE) File "/usr/lib/pymodules/python2.6/django/utils/translation/trans_real.py", line 194, in translation default_translation = _fetch(settings.LANGUAGE_CODE) File "/usr/lib/pymodules/python2.6/django/utils/translation/trans_real.py", line 180, in _fetch app = import_module(appname) File "/usr/lib/pymodules/python2.6/django/utils/importlib.py", line 35, in import_module __import__(name) ImportError: No module named basic My settings.py is as follows: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'apstat.basic', 'django.contrib.admin', ) If I remove the apstat.basic, it goes through, but that is not a solution.

If someone can help me out, it would be very nice.

• How to set up Mod_WSGI for Python on Ubuntu

  - by AutomatedTester

  Hi, I am trying to setup MOD_WSGI on my Ubuntu box. I have found steps that said I needed to do the following steps I found at http://ubuntuforums.org/showthread.php?t=833766 sudo apt-get install libapache2-mod-wsgi sudo a2enmod mod-wsgi sudo /etc/init.d/apache2 restart sudo gedit /etc/apache2/sites-available/default and update the Directory <Directory /var/www/> Options Indexes FollowSymLinks MultiViews ExecCGI AddHandler cgi-script .cgi AddHandler wsgi-script .wsgi AllowOverride None Order allow,deny allow from all </Directory> sudo /etc/init.d/apache2 restart Created test.wsgi with def application(environ, start_response): status = '200 OK' output = 'Hello World!' response_headers = [('Content-type', 'text/plain'), ('Content-Length', str(len(output)))] start_response(status, response_headers) return [output] Step 2 fails because it says it can't find mod-wsgi even though the apt-get found it. If I carry on with the steps the python app just shows as plain text in a browser. Any ideas what I have done wrong?

• Problem with deploying django application on mod_wsgi

  - by Shehzad009

  Hello, I seem to have a problem deploying django with mod_wsgi. In the past I've used mod_python but I want to make the change. I have been using Graham Dumpleton notes here http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango1, but it still seem to not work. I get a Internal Server Error. django.wsgi file: import os import sys sys.path.append('/var/www/html') sys.path.append('/var/www/html/c2duo_crm') os.environ['DJANGO_SETTINGS_MODULE'] = 'c2duo_crm.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() WSGIScriptAlias / /var/www/html/c2duo_crm/apache/django.wsgi Apache httpd file: <Directory /var/www/html/c2duo_crm/apache> Order allow,deny Allow from all </Directory> In my apache error log, it says I have this error This is not all of it, but I've got the most important part: [Errno 13] Permission denied: '/.python-eggs' [Thu Mar 03 14:59:25 2011] [error] [client 127.0.0.1] [Thu Mar 03 14:59:25 2011] [error] [client 127.0.0.1] The Python egg cache directory is currently set to: [Thu Mar 03 14:59:25 2011] [error] [client 127.0.0.1] [Thu Mar 03 14:59:25 2011] [error] [client 127.0.0.1] /.python-eggs [Thu Mar 03 14:59:25 2011] [error] [client 127.0.0.1] [Thu Mar 03 14:59:25 2011] [error] [client 127.0.0.1] Perhaps your account does not have write access to this directory?
