What I think you need in the Parent model is access to the "through" 
table - say Parent_Child - which has a foreign key to both Parent and 
Child called Parent_Child.parent and Parent_Child.child respectively.


Like this ...

class Parent(models.Model):
child = models.ManyToManyField('Child',  through='Parent_Child')
#
..
def save(self, *args, **kwargs):
obj_qs = Parent_Child.objects.filter(parent=self)
# which gives you a query set to play with and extract obj
# or if you know the child object
# obj = Parent_Child.objects.get(parent=self, child=whatever)
# which gives you obj
# then ...
data_I_need = obj.thingummy
super(Parent, self).save(*args, **kwargs)

This is not necessarily the correct way to do things. I think there 
might be Django shortcut but I'm not immediately familiar with it. I'd 
have to read the query docs.

Re: Object level permissions implementation

[Jani Tiainen]

That's something I had in mind also.

And I think that is quite a best thing to do.

I'm not sure this is the best way to do it, but for what I think is a
similar situation, I created a template tag and a model instance method.

The template tag asks the model instance method whether the user has
permission.

Here's the template tag:

Re: Automating deployments

[Barry Morrison]

I've got SaltStack setup to deploy Ubuntu+Nginx+uWSGI+Postgresql+memcache 
pretty easily.  Pulls Django projects from Git, pip installs from

It is a lot less complicated than Puppet/Chef in my opinion. 

Just my $.03 cents

Re: Need guidance on static website conversion to Django

[Harry Houdini]

Maintaining that many static files has really got to suck, this is where 
Django is going to help you a lot. First step for you because you are just 
starting out it to play around with Django, build some base templates and 
try extending them until you get your templates looking how you want. Then 
go ahead and design the DB in a way that makes sense for making it easy to 
edit and display your site content (and to add whatever features on top of 
that you want- e.g the voting thing you wanted to add). 

And overall think it would make more sense to start with a vanilla Django 
install and get a feel for it before you jump to Mezzanine. I looked at 
Mezzanine for a project and spent a few days messing around with it and 
building up a site and I have to say that it adds a ton of functionality on 
top of Django but has a learning curve when it comes to customization. They 
modified django a lot compared to something like DjangoCMS I would say 
(which is more of a plugin). Mezzanine is also pretty new and under very 
active development (I follow their repo on Github, its pretty active) but 
you can usually talk to people on their IRC channel about it if you get 
stuck (its on freenode). 

You might find you can build it fast enough with vanilla Django and a few 
unobtrusive plugins and that you dont need the CMS stuff (django.admin does 
a lot actually but has some limits).

Re: Problen with Custom command and Bash Script

[Jesús Lucas Flores]

Hi guys,

Thanks everybody for all the answers, really helped me.

I *SOLVED the problem.*

The problem was I was calling custom enviroment variables into my 
settings.py . So that enviroments variables exists on bash (thanks to 
.bashrc) but not in cron  ( thanks Branko Majic ) so manage.py failed  to 
load and no load at all .

I fixed calling my env variables in cron like this:

2 * * * * * root  . $HOME/.basrc; /root/env/project/script.sh

Thank you  to everybody
And sorry about my english.

Why doesn't form_valid() in FormView take a request argument?

[Some Developer]

Why doesn't the form_valid() (and for that matter the form_invalid()) 
method in the FormView generic class based view take a request argument?


I've found that if you have a form which requires you to override the 
form_valid() method because you need to do custom logic before you save 
the model and you need to save the user ID of the person who posted the 
form you need to also override the post() method in order to pass on the 
correct data by manually adding it to the post argument of the 
form_valid() method by using request.user.


Am I missing something here? Is there any easier way to achieve what I 
want to achieve?

Django and mod_wsgi serving different apps from separate virtual hosts on the same server

[robertlnewman]

Hi fellow Django devs,

I have been going around and around trying to figure this out for 2 days, 
without success. I am trying to serve two Django sites from one webserver using 
Apache's virtual hosts. The first works, the second doesn't. (Note that I have 
been happily serving Django content via mod_wsgi on Apache for one virtual host 
for the better part of a year already, so I am not a newbie.)

For background we are running Django 1.4.2 within a virtualenv and serving via 
Apache 2.2.

We have one project directory '/path/to/django/www' where all our apps live. I 
have all my settings and wsgi files for each site in:

/path/to/django/www/site1/settings
/path/to/django/www/site1/apache

and

/path/to/django/www/site2/settings
/path/to/django/www/site2/apache

I have my apps in '/path/to/django/www' called (for example) Foo, Bar and Baz

I want to serve apps Foo and Bar from port 8787 and app Baz from port 8788. I 
want them all to have their content updated via one admin interface on port 
8787.

I suspect it has to do with https://code.djangoproject.com/ticket/18518 so I 
have configured Django to run in mod_wsgi daemon mode. I followed the 
instructions here and here and also read Graham Dumpleton's blog post on the 
topic here but it still doesn't work. I am turning to this discussion group as 
a last resort.

Here are my Apache virtual host containers:

###
# Start Python WSGI configurations

Listen 8787
NameVirtualHost *:8787


  DocumentRoot  /path/to/django/www/site1
  ErrorLog "/path/to/django-8787-error_log"
  LogLevel info
  WSGIDaemonProcess  django-site1
  WSGIScriptAlias / /path/to/django/www/site1/apache/django.wsgi


Listen 8788
NameVirtualHost *:8788


  DocumentRoot  /path/to/django/www/site2
  ErrorLog "/path/to/django-8788-error_log"
  LogLevel info
  WSGIDaemonProcess  django-site2
  WSGIScriptAlias / /path/to/django/www/site2/apache/django.wsgi


# End Python WSGI configurations
###

We don't run Apache from the root user (we run it as user apache) so I don't 
AFAIK need to define anything other than a name for the WSGIDaemonProcess to 
live under (i.e. I don't have to define the name or group options).

Here are the contents of my django.wsgi files. You can see some of my 
experiments in trying to get this to work (lines commented out) based on the 
tickets and documentation linked above:

site1 (site1/apache/django.wsgi)

import os, sys
sys.path.append('/path/to/django/www/site1')

# Quick fix, but not great
# os.environ['DJANGO_SETTINGS_MODULE'] = 'site1.settings'

# Original setting - use Apache mod_wsgi settings to control
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'site1.settings')

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

site2 (site2/apache/django.wsgi)

import os, sys
sys.path.append('/path/to/django/www/site2')

# Quick fix, but not great
# os.environ['DJANGO_SETTINGS_MODULE'] = 'site2.settings'

# Original setting - use Apache mod_wsgi settings to control
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'site2.settings')

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()


Interestingly, when I deploy these files and restart Apache I only get relevant 
output in the custom error log for site1 (in /path/to/django-8787-error_log) 
(Note also that this shows a complete shutdown and startup series of notices):

It can be surprising sometimes what code can cause other code to get
imported and run. My guess is, in trying to find your url route there,
Django looks through ntw.urls. When it sees 'receipts' it imports
ntw.checkout.views to see if that view is there. Suffice it to say,
Django is trying to run the code in ntw\checkout\views.py and it would
be a good idea to make it work.

Django gives you the line in the file where the error occurs so you
don't need to track it down ;-)
It's probably failing when you try to import something in views.py.

No module named models again

[frocco]

Hello,

What is the best way to track down these types of errors?

in ntw.urls I have: (r'^checkout/', include('checkout.urls')),

in checkout I have:
urlpatterns = patterns('checkout.views',
#(r'^$', 'show_checkout', {'template_name': 'checkout/checkout.html' }, 
'checkout'),
(r'^receipt/$', 'receipt', {'template_name': 'checkout/receipt.html' 
},'checkout'),
)

if I comment out receipt, the error goes away.

in checkout.views
def receipt(request, template_name='checkout/receipt.html'):
""" page displayed with order information after an order has been 
placed successfully """
order_number = request.session.get('order_number','')
if order_number:
order = Order.objects.filter(id=order_number)[0]
order_items = OrderItem.objects.filter(order=order)
else:
pass
#cart_url = urlresolvers.reverse('show_cart')
   # return HttpResponseRedirect(cart_url)
return render_to_response(template_name, locals(), 
context_instance=RequestContext(request))

Re: Problen with Custom command and Bash Script

[Ali]

I think this has to do with not mentioning the proper settings file. 
manage.py goes to the settings and checks all the installed apps for any 
custom commands, but if you haven't set proper settings file then it would 
not recognize those commands. You can either set the environment variable 
to DJANGO_SETTINGS_MODULE=your_settings_file 
or mention it in the command
python manage.py test --settings=YOUR_SETTINGS_FILE_NAME (dont have to 
mention .py)

Are you sure the script functions even without activating the virtual
environment?

Have you perhaps set some environment variables in your regular account
that are not available during the cron execution?

Keep in mind that cron executes jobs with bare minimum of environment
variables set. You could check the environment variables set by cron by
adding a line to your script that goes something like:

/usr/bin/printenv > /tmp/cronjob_envvars

You could then compare output from that file to the output of the
printenv command that you run by hand.

Best regards

settings.py have the database configured properly?

Re: Object level permissions implementation

[bobhaugen]

I'm not sure this is the best way to do it, but for what I think is a 
similar situation, I created a template tag and a model instance method.

The template tag asks the model instance method whether the user has 
permission.

Here's the template tag:
https://github.com/bhaugen/localecon/blob/master/clusters/templatetags/permissions.py

Here's the instance method:

Local Flavor - PhoneNumberField (KeyError: Invalid)

[Derrick Jackson]

Hi all,

I am working on implementing the US PhoneNumberField and currently as long 
as I pass in the expected phone number length (10 digits) the number is 
formatting numbers just as I expect.  However, if I dont put enough numbers 
in the form field, I get a Key Error.  

I can't for the life of me figure out how to override the validation of 
this form field prior to the PhoneNumberField trying to format the number. 
 Any advice would be appreciated.

Thanks

Re: admin - see detail inline

[Victor Rocha]

I see more than one problem with your code. StackedInline is only used for 
models that have a one to many relationship and not the otherway around, in 
other words, you can have Docs stacked in line on the Client page but not 
the other way around, because only ONE client owns the document. You will 
see who owns it unless you have editable=False in your foreignkey.  The 
code should look like this:

#Model
class Client(models.Model):
name= models.CharField(max_length=25)
...

class Docs(models.Model):
name= models.CharField(max_length=25)
...
client  = models.ForeignKey(Client)

#Admin
class Detail_Doc(admin.StackedInline):
model = Docs

class DocAdmin(admin.ModelAdmin):
pass

class ClientAdmin(admin.ModelAdmin):
inlines = [Detail_Doc,]

admin.site.register(Doc, DocAdmin)
admin.site.register(Client, ClientAdmin)

That would probably depend on whether we're talking about specific physical
items in the WishListItem model, in which case each can obviously belong to
only one customer, or catalog items, each of which can be bought by
multiple customers. Since this is a wishlist, my guess is that they're not
physical items and more than one customer can have the same item on their
wish list, so a ManyToManyField would work.

Re: plz help me for error in python for django.....

[Jani Tiainen]

Django doesn't touch tables that already exists in database.

So if you had model Poll run syncdb and then change, add or remove 
fields Django doesn't modify underlying table.


There is few options that resolves your problem:
- Manually migrate your database using plain SQL.
- Recreate table or whole database.
- Use south for database migrations.

Interesting error with django.simple.test.DjangoTestSuiteRunner

[chris]

Hi everyone,

We've been having this miscellaneous error with the default test runner in 
Django. We had a forms.py that was something like this:

class SomeForm(forms.ModelForm):
some_field = 
some_custom_fields.SomeCustomField(choices=get_some_queryset_and_evaluate_it())
# Actually, we're using django-chosen's ChosenGroupChoiceField, so 
choices is a specially-constructed 4-D list of objects

And our tests.py had:

from forms import SomeForm

Per the Django documentation, the tests are all imported before the test 
database and tables are created. This means our tests.py imports SomeForm, 
which in turn calls get_some_queryset_and_evaluate_it(), which in turn 
causes a DatabaseError: no such table: some_app_some_table, since the 
database hasn't been created yet.

So, a few questions.


   1. Should the test runner's behavior be changed?
   2. Even if it should be, what's the best way to avoid this right now? We 
   were thinking of either 
   subclassing django.simple.test.DjangoTestSuiteRunner and altering it to 
   create the database before importing tests (seems fragile), or simply 
   modifying the choices in SomeForm's __init__ method (seems hacky).

Thanks,
Chris
