Re: Django in production on Windows

[ashdesigner]

Sam,

That's exactly what we arrived at: PyISAPIe doesn't work with IIS, so
I will install an Apache pack on Windows.

We've already launched a VMWare (Win VPS) with no IIS running on it,
and I lean to XAMPP as an appropriate Apache out-of-box pack to run on
the Win platform. What would you say? Will it do for development AND
production modes? Or shall I 'poke around' any other Apache distro?

p.s. The only thing I would avoid is dealing purely with Apache
configs: I need a distro to be set up and running asap, that's why I'm
thinking of XAMPP.

Not sure where you're getting this information from, but assuming
you're using the latest Django:

http://docs.djangoproject.com/en/dev/ref/settings/#std:setting-LOGIN_URL

i.e. you should be using settings.LOGIN_URL and not
django.contrib.auth.LOGIN_URL since at least 1.0

newbie question: @login_required, can't get it to work

[Charlietuna]

Hi All,

I'm a newbie. I would like to use the @login_required decorator, but I
don't want to redirect to the standard default accounts/login. I would
like to redirect to '/login/'

The book says add the following to the end of the settings.py file.:

import django.contrib.auth
django.contrib.auth.LOGIN_URL = '/login/'


The server says: GET /accounts/login/?login/=/save/ HTTP/1.1  404 2273
I assume that it is going the path:

/account/login/login

Any help would be appreciated!

Thanks,

Steve

Re: django-extensions - "Error: no module named django_extensions"

[Victor Hooi]

heya,


Thanks for the reply. I'm fairly sure it is in the PYTHONPATH.


I'm using virtualenvs and pip to install, so it should be there in the
system-wide Python directory for that environment.


Also, as per my first post, I can import it fine from a Python shell,
it's just it seems to act up within Django...*confused*.


Cheers,
Victor

Re: FileField and location and storage

[Sam Lai]

Some more background -

If you look at lines 228 to 230 of django/db/models/fields/files.py,
you'll see that the generate_filename method is overwritten by your
upload_to method if you specify one.

228 self.upload_to = upload_to
229 if callable(upload_to):
230 self.generate_filename = upload_to

Re: FileField and location and storage

[Sam Lai]

I have a custom file storage working with a specific subdir structure.

Did you pass in a method specifying the path in the upload_to kwarg
for FileField?

Here's my model code, where EnhancedFileSystemStorage is my custom
file storage class, and get_random_dir_name is just a helper method
that does exactly as named.

file_storage = EnhancedFileSystemStorage(location=settings.DYNMEDIA_ROOT,
 base_url=settings.DYNMEDIA_URL)

def file_upload_to(instance, filename):
return os.path.join(get_random_dir_name(instance.file_storage.location,
filename), filename)

file = models.FileField(upload_to=file_upload_to, storage=file_storage)

I've successfully got the data I was after, and I've even got it into
the template with success - thankyou!

The problem I now have is that the data returned has the format:

language,number,percent

where language = short language code.

In the template I'd like to represent language in it's long form, but
am having all types of trouble getting it to do so. I have the longs
in a dictionary in my models.py, in my views.py I've created a smaller
dict of long_langs, but how do I then match them in the template?

Here's some of my template attempts:

these proved that the data is coming through to the template
{{ target_stats }}
{# {{ long_langs  }} #}
{#  {{ lang_dict }}  #}

These loops didn't work (for obvious reasons...)

  {% for language, number, percent in target_stats %}
{{ long_lang.foorloop.counter }} {{ number }} {{ percent }} 
  {% endfor %}

and

  {% for language, number, percent in target_stats %}
{{ lang_dict[language] }} {{ number }} {{ percent }} 
  {% endfor %}

there have been a few other attempts - mostly riffs on those
themes...I even tried a
for(for(if))) but nothing came out.

I'm confused about how to get this right

cheers
L.

django-extensions - "Error: no module named django_extensions"

[Victor Hooi]

heya,


I original thought to post this in the django-extensions group, however
that seems like a fairly low-traffic group, so I thought I'd post here
in the hopes somebody here might be able to figure it out.


Basically, I've installed django-extensions via Pip
pip install django-extensions
Whenever I try to run any manage.py commands in my project, I get an
error:
Error: No module named django_extensions
In my settings.py, I have:
INSTALLED_APPS = (

'django_extensions',
In the Python shell,I can do a "import django_extensions" and it
imports fine with no error messages.


Not sure what's going on here?


I also tried with django-extensions from Github, same error.


Cheers,
Victor

django session InvalidOperation

[kinder]

I'm fairly new to Django, and I'm trying to move an existing Django
application to a new server. The old server is running Django 1.0.2
and Python 2.5.4. The closest I could come on my new server (to start)
is Django 1.0.4 and Python 2.5.5.

Anyway, I get an admin login screen, but when I try to log in, I get
an error:

Exception Type: InvalidOperation
Exception Value:Invalid literal for Decimal: '2010-12-22 17:36:30'
Exception Location: build/bdist.linux-i686/egg/MySQLdb/connections.py
in defaulterrorhandler, line 35

If I'm reading the error page right, it looks like it's happening in
db/models/query.py, somewhere around here:

 316. clone = self.filter(*args, **kwargs)
 317. num = len(clone) ...

Any advice on how to get past this?

Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

Why the file is executed twice ? I don't want to have twice the same
threads.

Thank you

mart



__init__.py files aren't executed at the start of programs, the
presence of them denotes that a directory is a python module, and the
__init__.py is executed when that module is first imported under a
particular name.

Do you have a structure like this:

project
├── __init__.py
├── app1
│   └── __init__.py
└── app2
 ├── __init__.py
 └── models.py

and import from project.app2.models and from app2.models? That would
cause app2's __init__.py to be executed twice.

Cheers

Tom



Yes the structure of my project is more or less like that but I've not
two but 6 apps all with 'from django.db import models' in models.py
In several model (more than two), I'm using foreign keys to different
models.
For now the site doesn't do much, I'm using the database created with
the models in other files in the project folder.

So if the __init__.py is not a good place to start operations at server
startup, where should I put it ?


It seems like a good place to put it. Maybe you can test to see if the 
threads have been started already?


Here is a singleton which could live in your __init__.py and might help 
to record the state of your threading ... or anything else for that matter.


class singleton(object):
""" designed by Oren Tirosh and Jeff Pitman """
def __new__(self, *args, **kwargs):
if not '_singleton' in self.__dict__:
slate = object.__new__(self)
slate.state = {
'threads':True,
# add other state things as required
}
self._singleton = slate
return self._singleton

CSRF missing token

[martvefun]

Hello,

I've a login form which give me an CSRF error.
In the documentation, I read that I needed to have in my code :

# views.py
...
csrf_token = {}
csrf_token.update(csrf(request))
return render_to_response('index.html', locals())

# index.html
...

 {% csrf_token %}

But I've an error that the two tokens are different
I guess the problem is in the generation of the token :


}' />


It should use value="{'csrf_ instead of value='{'csrf._..

Any idea how to fix ?

Thanks

I would guess that the problem lies somewhere in your admin file
(admin.py).  What are the contents of it?

Hello,

I'm not sure I understand the question so am making the following
assumptions.  Sorry if this isn't what you are looking for.

   1. You know how to access the generated content.
   2. You want to serve the content as a file with a specific name.

For this example let's say your file is a CSV file with content in
FILE_CONTENT.  You will need to set a few thing up in you http
response to serve up a proper csv file.

response = HttpResponse(mimetype='text/csv')
response['Content-Disposition'] = 'attachment; filename=%s' %
'MyRandomFileName'
response.write(FILE_CONTENT)
return response

You can set other header options like Expires, Content-Length, etc. in
this fashion.

Hope I helped.
Mark

Django template tags.

[Nuño Iglesias]

Hi, i think it's the first time i write to this list, so 
 Hello to everybody...¡¡


Well, now my problem.
I'm trying to use "template filters" in one of my templates.

What i'm trying to do is this:
   {{ mystring | upper }}
to convert "mystring" into upper-case.

but Django is complaining:
TemplateSyntaxError at /
Could not parse the remainder:'| upper' from 'row.0 | upper'

I suppose I've forgotten to import something...but I cant find it. 

Any help ?

Thanks.

Nuño

Anyway, see also

Build up a parameterised query string dynamically (eurgh, I know):

l = ('Restaurants','Fast Food',)

pquery = "SELECT id FROM app_category WHERE name IN (%s)" % ',
'.join(["%s"]*len(l))

Category.objects.raw(pquery, l)[0]

FileField and location and storage

[dmitry b]

Hi,

I've written a custom Storage that uses WebDAV as its underlying
engine.  When I save a file '/foo/bar/file.ext', I want it to be saved
under /foo/bar in the webdav filesystem.  However, it seems that
FileField overrides the directory structure:

def generate_filename(self, instance, filename):
return os.path.join(self.get_directory_name(),
self.get_filename(filename))

where get_directory_name() is defined as

def get_directory_name(self):
return
os.path.normpath(force_unicode(datetime.datetime.now().strftime(smart_str(self.upload_to

I'm not really sure why FileField finds it appropriate to impose its
own directory structure on the underlying storage engine.  But short
of creating a custom subclass of FileField and overriding
generate_filename and/or get_directory_name(), is there a different
way of preserving the original file location path?


Thanks
Dmitry

Re: When to use Form API

[ringemup]

This.  Form processing is one of those tedious things 90% of which is
the same in every form: field definition, display, validation, and
error handling/presentation.

Django takes care of the repetitive parts, and if you need to
customize the validation or display, allows you to do so while still
abstracting away all the rest of the fiddly stuff.

If anything, manual form processing in Django would be overkill,
unless you have some special case that the form API simply can't
handle (e.g. nested formsets, although there are a few apps now that
enable that, IIRC)

That's a simplified sql just as an example.  The actual one I need the

Why use raw? Why not just use the ORM?

Category.objects.filter(name__in=['Restaurants', 'Fast Food'])

__init__.py files aren't executed at the start of programs, the
presence of them denotes that a directory is a python module, and the
__init__.py is executed when that module is first imported under a
particular name.

Do you have a structure like this:

project
├── __init__.py

__init__.py file executed twice ?

[martvefun]

Hello,

I'd like to start some threads when the server launch to listen to
events (I'm doing message passing).

To do so, I guess I should be using the __init__.py file at the root of
my project (by the way, what's the used of the other __init__.py files
in the apps)

I've tried with a simple test by only having 'print "starting server"'
into the file and the result is :

$ python manage.py runserver
starting server
starting server
Validating models...
0 errors found

Django version 1.2.3, using settings 'website.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

Why the file is executed twice ? I don't want to have twice the same
threads.

Thank you

mart

IN clause in raw sql

[dgmyrs]

Hi, I am trying to work with an in clause in my sql in a raw sql
statement.  A simplified example:


>>>Category.objects.raw('select * from app_category where name 
>>>in(\'Restaurants\',\'Fast Food\')')[0]



So that works fine with the in clause hard coded in there, and I could
simply build that sql string, but I am wondering if there is a way to
use the parameters argument of raw?  I tried using a list with the
strings, and just a string itself with the escaped quotes, but
couldn't get either to work.

Thanks

Re: When to use Form API

[Wayne Smith]

It is important to distinguish between display and functionality with
forms.  What I mean is, using the forms does not mean you have to render
(display) them the way Django has it set up by default.  I always use the
Form API, and if I need custom validation on a field or the entire form, I
override the appropriate clean method.  I pass the widget argument if I want
a different widget.

IMO, one of the best things about Django is the ease in which I can
customize its parts but still leverage its functionality.

can't add via admin, get django template error

[JeffH]

So I'm working along, everything's humming fine. Then I try to add a
record via the admin, and get the following:

TemplateSyntaxError at /admin/expert/expertresponse/add/
Caught AttributeError while rendering: 'unicode' object has no
attribute 'date'

[snip]

Template error

In template c:\python26\lib\site-packages\django\contrib\admin

I can add records via a ModelForm without problem, it just doesn't
work in the admin.

When to use Form API

[christian.posta]

Do django developers use the Form API any time form elements need to
be displayed to users? Or do you just code the form yourself in the
templates and manually process them for smaller forms?

In general, is it always better to use the Form API for any form you
display, regardless how simple, because of the built-in functionality
provided by django, or is it overkill?

You're probably simply not sending the user object to the template.
You need to either send it explicitly in the context, or ensure the
`auth` context processor is active and you're using RequestContext.

User not authenticated after login?

[gunnar]

Dear group,

I run django 1.2 on windows on the development server.

I set up a login site via the standard django login view. The user is
then redirected to a site built from a base template. The view that
calls the base template is only available to logged-in users (via the
@login_required decorator) - otherwise, the user is redirected to the
login site. This part works.

However, when I try to access {{user.username}} from within the
template, I find that it is empty. is_authenticated returns false.

What am I doing wrong?

Gunnar

Re: Help! I'm thick! First formset generating AttributeError

[fgasperino]

While I haven't worked with formsets, this line doesn't look correct:

formset = ClientFormSet(request.POST, request.FILES,
queryset=Client.objects.get(pk=client_id))

mainly due to a parameter named queryset being passed a model object,
instead of a queryset of model objects. It would seem that you want
queryset=Client.objects.filter(pk=client_id) to achieve the same
result.

Then again, I could be wildly off.

Help! I'm thick! First formset generating AttributeError

[morgand]

Either its age - the scotch - or some combination of both, but I am
having problems with a SIMPLE formset. (its my first).

On my formset I get an AttributeError - 'Client' object has no
attribute 'ordered'... .but I dont have an attribute of that
anywhere I tried changing from a "get" to a "raw" but still
get a (similar) message.

My code is :
(models.py)

class Client(models.Model):
title = models.CharField(max_length=3, choices=TITLE_CHOICES)
firstname = models.CharField(max_length=50)
lastname = models.CharField(max_length=50)
mobilenumber = models.CharField(max_length=50)
phonenumber = models.CharField(max_length=50)
email = models.CharField(max_length=50)
street = models.CharField(max_length=50)
city = models.CharField(max_length=50)
state = models.CharField(max_length=10, choices=STATE_CHOICES)
class Meta:
ordering = ('lastname','firstname')
unique_together = ('firstname', 'lastname','mobilenumber')

def __unicode__(self):
return self.id


I have a forms.py containing

ClientFormSet = modelformset_factory(Client, extra=0, max_num=1)


In my view.py" I have the following... which is getting called and is
what generates the error

def c4(request, client_id=None):
if  client_id == None:
if request.method == 'POST':
formset = ClientFormSet(request.POST, request.FILES)
if formset.is_valid():
formset.save()
clients = Client.objects.all()
return SortableGrid(request,
clients).render_to_response("mylibrary/real.html")
else:
formset = ClientFormSet(request.POST, request.FILES)

else:
if request.method == 'POST':
formset = ClientFormSet(request.POST, request.FILES,
queryset=Client.objects.get(pk=client_id))
if formset.is_valid():
formset.save()
clients = Client.objects.all()
return SortableGrid(request,
clients).render_to_response("mylibrary/real.html")

else:
formset = ClientFormSet(request.POST, request.FILES,
queryset=Client.objects.get(pk=client_id))

return render_to_response("4.html", {
"formset": formset,
})


My "4.html" contains

{{ formset.management_form }}
{% for form in formset.forms %}
{{ form.id }}

{{ form.id }}
{{ form.firstname }}
{{ form.lastname }}

{% endfor %}

100% fixed. I was calling save() on the form twice, once in form_capture and
once in form_errors.

It is. Please refer to the relevant RFC:  the question mark is a
reserved character used to specify the beginning of a querystring. If
you want it to be part of the url itself, you do have to properly
quote it (using django.utils.http.urlquote or the corresponding
template tag).

The url regexp is matched against the "path" part of the url - the
querystring is ignored at this point.

50% solved - I passed request.FILES into the form's constructor as indicated

I then accessed the file as follows:

attachment = request.FILES['attachment']


Only problem left is to figure out why the form is posting twice. ideas

Form attachment (FileField) upload not saving.

[Sithembewena Lloyd Dube]

Hi all,

I have a contact form that is supposed to save a message as well as a file
upload. When I use the admin site, I can save a contact record with a file
upload of any type.

However, saving from the 'front end' of my web application causes some
strange behaviour - the file is not uploaded, and the contact record is
saved twice as seen from the admin site.


My code is as follows:

BEGIN
CODE---
*html template:*

{%
csrf_token %}


Message
{{ form.message }}


Upload File:
{{ form.attachment }}

 





*view*:

@csrf_protect
def contact_us(request):
form = form_capture(request)
return render_to_response('front_end/standard_pages/contactus.html',
{'form': form, }, context_instance=RequestContext(request))

*the form_capture function (extra module named functions.py - keeps all my
custom functions)*:

def form_capture(request):
 if request.method == 'POST':
  form = ContactForm(request.POST)
  if form.is_valid():
   message = form.cleaned_data['message']
   attachment = form.cleaned_data['attachment']
   form.save()
 else:
form = ContactForm()
 return form

*the form (forms.py):*

class ContactForm(ModelForm):
 class Meta:
  model = Contact
 message = forms.CharField(widget=forms.Textarea(attrs={'cols': 60,
'rows': 10, 'class': 'mceNoEditor'}))
 attachment = forms.FileField(required=False, widget=forms.FileInput())

*the Contact model (models.py):*

class Contact(models.Model):

 message = models.TextField(max_length=500)
 attachment = models.FileField(upload_to='attachments', blank=True)

 def __unicode__(self):
  return self.message[:10] + '...'

 class Meta:
  verbose_name_plural = "Contact Messages"

END
CODE---

Any ideas why saving a record from the contact form posts twice, and why the
file attachment is not uploaded?

Thanks!

Re: Post URL characters problem

[Keats]

hi,
How i can add it then ?

i was thinking that the problem is "?" because :

works perfectly any other characters in the topic_name part seems to
work and since i'm only using : (.*) i didn't see how it could be an
URL mismatch matter because for me (.*) means match everything ...

thanx.
