Re: Streamlining DJango Deployment — Novel idea from the world of CMSs

[Alec Taylor]

Looks like the initial mockup for the final display didn't Ctrl+V properly, 
here it is: http://i55.tinypic.com/s5fivd.png

The problem I'm trying to solve is one of deployment (and minimalist 
overview management).

When I write a project, I want whoever needs to install it to be able to 
install it, and get it up and running with as little skill as possible. 
Since what I'm writing isn't just for developers but are also for other 
enthusiasts and conference organisers; simple install is a must.

Also, for development, it would be quicker+easier to get a development 
environment/build up and running on a new machine with the aforementioned 
interface.

Re: multiple filters on the same (reversed) foreignkey leads to multiple join

[Peter of the Norse]

That is expected behavior. The filter should be read as “there is a child with 
flag1 equals true”. Another example where this is the desired behavior would be 
Band.objects.filter(member__name='John', member__name='Paul', 
member__name='George', member__name='Ringo') . In this case you are looking for 
a band with at least four different members.

Is there an example or tutorial showing how to write a decorator? I'm
interested in automatically converting the url parameter that comes in
as a string. So 'None' converts to the object None.

How would one write a decorator to take a list of types? I'm
interested in automatically converted the URL parameter string 'None'
to the object type None.

Re: django and thrift

[Li Lirong]

Hi,
Thank you for your comments.  I am new to both django and thrift.  I
am hosting my service with a shared web hosting server.  That's why I
want to use django to expose a thrift API.  Basically, what I want is
to have a web service that can be consumed by both python and c++.  Do
you think this is possible with django?

Thanks.

Re: Streamlining DJango Deployment — Novel idea from the world of CMSs

[Doug Ballance]

I would agree with Donald, and expand on that to say that an installer
would probably be best written in php for widest compatibility.  A php
based installer would run outof the box on most webservers, and be
able to give a guided overview of the python/web environment setup.
It would easily be able to detect the apache/webserver configuration
for required modules, make 'best practices' recommendations based on
the environment, download and setup virtualenv, etc.  Not a php fan,
but it would seem to me to be a prime choice for an installer to let
django/python webdevelopment ease into a php dominated world.

Re: How to group models month by month.

[Matteius]

I would suggest trying not to break up the date and simply use a
DateField and a separate IntegerField (or BigIntegerField).  Of course
you avoid using a DateTimeField since the time would be irrelevant,
and if you think the day is irrelevant think again.  Assign a meaning
to the date and your logic can be sound--perhaps the first date of the
month, or the start day then on a second DateField you can have the
end date.  Having a start/stop is probably more complex than is
required for what you are trying to do--if you want it by months I
would always just put the 1st of the month down.

#  Inside your Post model and in the file you will need:
from django.db import models
class Post(models.Model):

pub_date = models.DateField(_('Start Date'), help_text=_('Date the
month begins for this dataset.'))
count = models.IntegerField()


# Now in your view you can simply use the Django ORM:
Post.objects.all().order_by('-pub_date')
# Or add a month filter
Post.objects.all().filter(pub_date__year=2005).order_by('-pub_date')
Post.objects.all().filter(pub_date__gt=datetime.date(2005, 1,
3)).order_by('-pub_date')
# IF you had a foreign key, get that data also with select_related
Post.objects.all().filter(pub_date__year=2005).select_related('model_name').order_by('-
pub_date')
# You could also order by count
Post.objects.all().filter(pub_date__year=2011).order_by('count')


Hope this helps,
Matteius

psycopg2 and Binary

[Jonathan S]

Hi django users,

Not sure whether this is a bug or configuration issue.

I have a postgres with postgis setup. It works perfect on a postgres
8.4 machine, but it doesn't on a postgres 9.1 machine.

The problem is when constructing GIS queries.
django.contrib.gis relies on psycopg2.Binary for encoding binary data
like polygons.

When connected to the postgres 8.4 machine, output is double-quoted,
like  \\000\\000, but when connected to the 9.1 machine, the output of
Binary is only single quoted, like \000\000. This causes of course
encoding issues, because it conflicts with the null-termination.

Any help?

Thanks,
Jonathan

Thanks mike.
Yes i'm consider your suggestion. But i prefer to have the edits in
other model, because the original model remains a bit 'clean'.

Re: In unitTest, GET Formset returns 302 instead of 200

[Xinlei CHEN]

@Malcolm, Sorry It should be some bad pastes :(

Finally, I have solved the problem using the following 2 lines:

c = Client()
c.login(username='alex...@e.com', password='alex')

In fact, I can't login in with the following code
self.client.login(username='alex...@e.com', password='alex')

I don't know why. So if anyone knows the reason, why not share it without us
:)

Re: Streamlining DJango Deployment — Novel idea from the world of CMSs

[Donald Stufft]

 We talked a little on IRC, but just thought i'd reiterate my thoughts.  

This should not be in core, and I don't believe it ever has a chance of being 
in core.

That being said, I think that an external "installer" app like this wouldn't be 
the worst thing in the world, and could help to make an out out of the box 
Django Project (not django itself) an easier thing to distribute.

I think if you go forward with this you'll best serve yourself, and the 
community by not making it django specific, but instead make an easy way to 
create a self contained installer/runtime container for wsgi based projects and 
then someone who creates a project in Django (like say a wordpress like site, 
or a forum like site), and wants to prepackage it for the masses can then use 
your project to create an easy installer/deployment container to get started 
with the project.

If this is a cut'n'paste of your code, you have a typo in the

Streamlining DJango Deployment — Novel idea from the world of CMSs

[Alec Taylor]

Good morning,

I have just recently starting migrating over from WordPress and Drupal to 
the world of DJango.

First of all, let me say that yes, I am aware that DJango is not a CMS!!!

Now, onto my suggestions on how to streamline DJango deployment.


= What's wrong with the current method? =

• Doesn't cater to people who don't know Python
• Requires the installer to be a developer (pretty much)


I'm building a social-network catering to student-groups, users-groups and 
game-clans. I will be releasing this under (probably) the New BSD license. 
Because I want as many people as possible to be able to use this project, I 
want to make it very easy for non-developers to setup this social-network on 
there servers.


= What are you suggesting? =

A four-step install process.
• Install pre-packaged Python+DJango-script package
• http://i53.tinypic.com/2055fg8.png
• http://i55.tinypic.com/e8lgtg.png
• http://i55.tinypic.com/o0qiow.png
• http://i55.tinypic.com/o0qiow.png


What are your thoughts on the DJango deployment redesign?

Would anyone be interested in getting involved (making this happen!)?

Best regards,

Alec Taylor

django-nani usage

[Janis Meiers]

Hello,
Does anyone use django-nani for model translations?
I'm a newbie to django, and my question is:
How do you switch languages in after you've set up your translations
with django-nani?
Do I have to set up a url in urls.py with language codes in it,
and then in corresponding view filter my database queries based on
language code received from url
and then pass filtered query to the template?

Thanks in advance,
Peter

In unitTest, GET Formset returns 302 instead of 200

[MATHIEU]

Hi,
I want to test the GET method for an inline formset.
The view in which the inline formset is created is as follows:

@login_required
def patron_edit_phone(request, *args, **kwargs):
patron = request.user
PhoneNumberFormSet = inlineformset_factory(Patron,
PhoneNumber, extra=1, exclude="kind",can_order=True)
if request.method == "POST":
formset = PhoneNumberFormSet(request.POST, request.FILES,
instance=patron)
if formset.is_valid():
formset.save()
messages.success(request, _(u"Votre information de
numéro de téléphone a bien été mise à jour"))
else:
formset = PhoneNumberFormSet(instance=patron)

return direct_to_template(request, 'accounts/
patron_phone_edit.html', extra_context={'formset': formset})



I have succeeded to test the POST method. Here is the code.

def test_patron_phone_edit(self):
self.client.login(username='alex...@e.com',
password='alex')
response = self.client.post(reverse('patron_edit_phone'),
{
'phones-TOTAL_FORMS': u'1',
'phones-INITIAL_FORMS': u'',
'phones-MAX_NUM_FORMS': u'',

'phones-0-id' : '1',
'phones-0-patron' : '1',
'phones-0-number' : "",
'phones-0-DELETE' : u''
})
self.assertEquals(response.status_code, 200)



For the GET method, I have tried the following code:

def test_patron_phone_get_form(self):
self.client.login(usernamer='alex...@e.com',
password='alex')
response = self.client.get(reverse('patron_edit_phone'))
self.assertEquals(response.status_code, 200)

But this doesn't work. Instead of getting a status_code=200, I get a
status_code=302. Why?
And when I print response.content, I get "None".
Perhaps I need to specify the total forms for the GET method?

Any help is highly appreciated!Thanks!

If more information is needed, tell me.

Re: Session value persistence between views

[alaric]

Hi:
Thanks for the reply. Actually, really dumb mistake, of course. I was
using the default django login view to authenticate, which means that
my view called "login" was never storing the session value! Once I
used my own login view, I was able to store my values correctly.

Here we add another two functions:
def get_urls(self):

from django.conf.urls.defaults import patterns, url
urls = super(MyAdmin, self).get_urls()
my_urls = patterns('',
(r'^admin/$', self.admin_view(self.index))
)
return my_urls+urls
 
The first one adds our url pattern to the admin urls. It's important to
use admin_view as wrapper for self.index – that was actually the
problem with the login. I haven't wrapped my view with admin_view.

To get this function called, you need to write function with property
decorator, which returns get_urls and... (see below). Actually that was
the other big problem – I tried to set property like that: urls =
property(get_urls) but it doesn't work, because get_urls returns only
the list with the urls, but no app_name and name.

@property
def urls(self):
return self.get_urls(), self.app_name, self.name

And so it works.

Change to "movies_page = int(request.GET.get('movies_page', 1))" and it
should work

Thank you very much for your reply,
I changed it but I guess Im doing something wrong cause it still
doesnt work:
It tries to go to the right page now, but provides nothing although I
know there's more than one page:

in views.py
movies_page= int(request.GET.get('page','1'))
try:
moviesp = movpaginator.page(movies_page)...

in the template:
  {% if actors.has_previous %}

{% else %}

Possible, maybe. But almost certainly the wrong thing to do.

Thrift is a binary protocol that doesn't look much like HTTP. Attempting to
use a web framework to handle it will cause grief.

Use the Thrift Python bindings to write a server, either a straight Thrift
server or using Twisted. Then if you need access to things like the Django
ORM then use those in the server.

Don't try to tie handling Thrift into the Django
URL/HttpRequest/HttpResponse cycle or you'll go mad.

There's the problem right there. You're using the same page variable for
both sides, so inevitably you'll find they move together.

Put the movies page into a variable called movie_page, and the actors into
actor_page. Update your links in the template to use the right query for the
prev/next and all should work fine.

django comments: CSRF failure (randomly)

[Alessandro Pasotti]

Hi,

this issue is driving me mad, I'm using Django 1.2 with the
'django.contrib.comments' applications, randomly I get

'CSRF token missing or incorrect'

 'request_csrf_token': u'c22473c9626677f09a64c751df4bfa8a',
 'META': {'HTTP_COOKIE': 'csrftoken=c04574f981417a4667db264bb527239d;

there is a mismatch.

It's almost impossible to reproduce, but I' managed to activate logging with
a custom view and sometimes I receive the failure notice with the details,
they come from real users messages, not spammers.

Disabling the cache middleware doesn't seems to change anything.

Any hint about what I can further check ?

This is the order of my middlewares:

http://dpaste.com/610460/

Deployment is with apache/mod_wsgi:

WSGIDaemonProcess mysite.com user=www-data group=www-data processes=10
threads=1 display-name=WSGI

This can definitly be resolved with Django, and it's always better to
have something working without js / ajax when possible (you can then
add js / ajax afterward).

You probably just want to monkeypatch urlresolvers.reverse in your test 
setUp methods. Something like this would probably work.

from django.core import urlresolvers
reverse_original = urlresolvers.reverse
def reverse(*args, **kwargs):
url = reverse_original(*args, **kwargs)
url += whatever_you_want_to_add
return url
urlresolvers.reverse = reverse

Re: Static images for use in admin widget

[Micky Hulse]

Hi Tomas,

Thanks again for your tips and code samples, I really appreciate it.

I really liked that technique of using __init__.py to add a constant
to the settings.py file. Very cool!

I get what you mean now when you say "I think hardcoding the 'app/'
directory is the usual way to do this, you should be the one naming
your /static/app/ directory anyways"... Here's my current solution:

Top of my widgets.py file:

from django.conf import settings

(I removed the crosshair function and put it in a JS file in my apps'
static folder)

class Media:
js = (
'%smy_app/my_app.js' % settings.STATIC_URL,
)

In my_app.js, I link to crosshair.gif using a root-relative URI:

div.innerHTML = '';

(sometimes I wish JS could link to things relatively from the JS file
like css files do... Oh well, no harm in linking from the root path
here.)

With all that said, I did experiment with your suggestions. One
problem I ran into, was that os.path.dirname(__file__) returned a
server path to my apps' static folder (which is what I originally
asked for)... I soon remembered/realized that I needed a path to the
static collected folder, hence the use of the settings.STATIC_URL in
my widgets.py file.

Well, long story short (too late), as you can see, I did end up
hard-coding my app name into the widget file.

Like I said, I do like your technique of using __init__.py to add
vars/constants to the settings file. At one point, I was considering
doing something like this:

# __init__.py
settings.APP_NAME = 'my_app'
# Widget media JS:
'%s%s/location.js' % (settings.STATIC_URL, settings.APP_NAME),

But maybe that's serious overkill?

Anyway, many thanks for the inspiration and kick in the right direction. :)

Have an excellent night!

Cheers,
Micky

intercept calls to reverse(..) in tests

[Reikje]

Hi, I have a bunch of WebTest's which are using the reverse method
from django.core.urlresolvers to resolve a URL which the test should
call. Example:

url = reverse('webapp_home')
form = self.app.get(url).form

Now I need to add a query parameter to every url. This is to mimic a
Facebook request which will always have the signed_request query
parameter. So in theory I could just do this:

url = reverse('webapp_home') + "?
signed_request=vlXgu64BQGFSQrY0ZcJBZASMvYvTHu9GQ0YM9rjPSso.eyJhbGdvcml0aG0iOiJITUFDLVNIQTI1NiIsIjAiOiJwYXlsb2FkIn0"
form = self.app.get(url).form

This is an example of a signed_request from the Facebook
documentation. Since, I am a bit lazy, is there a way to sort of
intercept all calls to reverse and add the signed_request parameter
every time?

django and thrift

[leon]

Hi,

I have one question.  Is it possible to use Django to write thrift
(http://thrift.apache.org/) formated web service? If it is possible,
is there any sample?

Thank you!

Doh, yah... If my django-fu skills were better, then maybe I could! :)

I should have posted the original code:



I am modifying to include a crosshair on the map by adding a simple JS
(non-dynamic) function.

Hrmm, now you got me thinking.

Maybe I could put the non-dynamic JS in an external file and then link
to it using "class Media:" (js), and from there, all I would need to
do is link to the image using a relative path (all within my apps'
static folder)? I will have to give this a whirl. :)

Hehe!

Well, even if you are pulling things out of the "blue", you still ROCK!!! :D

Those are awesome tips/ideas/snippets! Thank you so much for helping
me out, I really appreciate it.

Thanks for giving me a huge kick in the right direction!

Have an awesome night.

Micky
