Can you elaborate on yours needs ? They are several CMS in Django:

- djagnocms 
- amstrongcms
- mezzanine

Re: database -> model -> charting

[Christian Schulz]

I installed with python2.7/1.4.5 some weeks ago , but I didn't use a 
BigIntegerField. What is your error message?



After trying this I find a problem with the types it can use. For 
example it does not seem to like BigIntegerField unless there is 
something else I am doing wrong. Thinking about it, maybe I am letting 
chartit do too much for me but I do like the idea of something doing 
the hard thinking for me :). I am using python 2.7 and django 1.5, are 
you using the same ?

Yes, it is a bug - in your code!

You cannot mix naive and non naive datetimes together - naive
datetimes are datetimes without a timezone. If you have USE_TZ=True in
your settings.py, then django will be using non naive datetimes
throughout, and so you must do also.

Django provides a lot of utils to allow you to make a naive datetime
into a non naive:

https://docs.djangoproject.com/en/1.5/ref/utils/#django-utils-timezone

So code like this would work:

from django.utils.timezone import make_aware, get_current_timezone
expire_datetime =
datetime.fromtimestamp(profile_form.cleaned_data['expired_time'])
expire_datetime = make_aware(expire_datetime, get_current_timezone())
request.session.set_expiry(expire_datetime)

Cheers

Tom

Ok, thank you very much for your reply.

Using django-autocomplete-light?

[Derek]

Hi

I am trying to get django-autocomplete-light (
https://github.com/yourlabs/django-autocomplete-light) working for my
project in the admin.  I have the following files and code, running with
Django 1.4.3.  In the edit form for the Company, the drop-down list for
country has been replaced by an empty edit box, but beyond that there is no
list displaying when I start typing...

I'd appreciate any ideas as to how to get this basic example working.

Thanks
Derek


# models.py

class Country(Model):
id = AutoField(primary_key=True)
code = CharField(unique=True, max_length=5)
name = CharField(unique=True, max_length=250)

class Company(Model):
id = AutoField(primary_key=True)
name = CharField(max_length=250)
country = ForeignKey(Country)

# autocomplete_light_registry.py

import autocomplete_light
from models import Country

class CountryAutocomplete(autocomplete_light.AutocompleteModelBase):
search_fields = ['^name', ]

autocomplete_light.register(Country, CountryAutocomplete)

# admin.py

import autocomplete_light
import autocomplete_light_registry

class CompanyForm(forms.ModelForm):
country = forms.ModelChoiceField(
Country.objects.all(),
widget=autocomplete_light.ChoiceWidget('CountryAutocomplete'))

class Meta:
model = Company

class CompanyAdmin(admin.ModelAdmin):
list_display = ('name', 'country', )
list_filter = ('country', )
form = CompanyForm

it insisting on a decimal, I cannot see where this is specified in the

It could be a problem with the simpleson.dumps options in django 1.5 vs. 
the included simplejson. I remember there was something...

Point System in django

[coded kid]

what is the best way to implement this? Users will pay a certain fee
and get some amount of points (100points) and for every video the user
watch, like 30points will be deducted. How can I go about this? is
there a package for point system in django?

Re: Please help me in Django

[Thomas Weholt]

First of all; have you followed the python tutorial and a good grasp on
python in general? If not, do a quick read of the python docs before trying
to learn django.

You'll have to install django after downloading it. Unpack django, cd into
the new django-folder and do a

python setup.py install

Then read the official django tutorial/docs. They are all exceptionally
good and should get you going.

Thomas

Re: database -> model -> charting

[tony gair]

I tried that on 1.5 and tried my code out in a 1.4 install. I get the same 
error.  Interestingly in stack overflow they mention this problem at 
http://stackoverflow.com/questions/8644060/caught-typeerror-while-rendering-init-got-an-unexpected-keyword-argument

and chartit in its own code seems to expect a decimal value regardless, so 
maybe decimal values are hardwired into the code

Re: database -> model -> charting

[tony gair]

I have subsequently located the problem. I think where the chartit.py 
supplies a parameter saying use_decimal=true is wrong. I have removed that 
parameter and found that it works with that change. 
Do you know if this is because of updates to jquery?

How does it all work

[Nafiul Islam]

Hi!

I've been using django for a little bit, and I gotta say I love the 
framework. But here's the thing, I don't know how it works. How everything 
fits together. So, what I wanted to ask is how does it all work? Say you 
have a server, and you have Python installed on it. How would you go about 
making a simple hello world web page, without django?

I would be grateful to any link to a comprehensive resource, that shows you 
how to make a simple Hello World webpage, from how you install software 
that you need to writing pure python (without a framework) that can handle 
requests, and work with databases.

I guess, what I'm asking is how do you make a very very basic website using 
Python, from start to finish on a server?

Re: How does it all work

[Thomas Weholt]

I'd take a look at the standard python docs, especially the things about
wsgi and httpserver, but this question is not django-specific so you might
have better look asking in a more python-specific forum, like
comp.lang.python (
https://groups.google.com/forum/?fromgroups#!forum/comp.lang.python )

There's a long way and lots of codelines from a basic "Hello world" webapp
to a framework like django, but you'll learn alot by starting with the
standard webrelated stuff in standard python.

Re: dictionary update sequence

[Bill Freeman]

Look very carefully at the urlpattern (in some urls.py) that corresponds to
this url tag.  Perhaps something there isn't acted upon until you use the
reverse stuff.

If you don't see the issue, and want to chase it in pdb, make a dummy view
that calls django.core.urlresolvers.reverse() with these arguments, and put
import pdb;pdb.set_trace() just before the reverse().  Access the view, the
step into the reverse() call, and see when it gets to the exception, and
where it got the arguments.  (It sounds like arguments to the update()
method of a dictionary, but it could be internal to the regular expressiom
application if you use named arguments.

Good luck.

Bill

Suggestions on caching queries for a single request on a subset of Views?

[Kurtis]

I have two views which perform a ton of DB queries. The views themselves 
don't perform the queries; they simply call quite a few Model methods to 
build the context data. I understand that I could simply build one method 
to re-use the data but I'd like to sustain the "Object Oriented" quality of 
the code I've developed.

If possible, I'd like to be able to cache these queries when these views 
are called. A lot of the queries are simply re-produced but perform 
different calculations or what-not based on the method called.

These views do not create persistent data; they simply hit the database and 
return calculated results from what's in there.

The caching mechanism should simply persist through the duration of the 
request. For example, subsequent requests should not use cached results 
from a previous request.

Let me know if anybody has suggestions or experience with implementing 
something along these lines. I have some 'creative' ideas on how to do it 
but I'd like to get some input first.

Thanks!

Re: Suggestions on caching queries for a single request on a subset of Views?

[Marcin Szamotulski]

Hi,

I am not en expert but since I had a similar problem I found a solution.
I just attached data I wanted to persist to the request.  You can put the
common code in a middleware to be computed early and then use it in your
views.  You can also add it to the session data (i.e. request.session)
and after you process the view delete it.  But then the session will be
marked as both accessed and modified, and even though at the end you
haven't change the data (since you deleted what you have added) it will
be written to the database (or a file depending which session backend
you use).

Best regards,
Marcin

Re: Suggestions on caching queries for a single request on a subset of Views?

[Nikolas Stevenson-Molnar]

I created a simple decorator for this purpose:

http://djangosnippets.org/snippets/2874/

Wrap your expensive model methods with @auto_memoize and the results
will be cached in memory for the duration of the request.

Re: dictionary update sequence

[Marcin Szamotulski]

Hi,

This error message one gets in the following way:

>>> dict('a')
ValueError: dictionary update sequence element #0 has length 1; 2 is 
required

I suspect that the second argument of your url is a keyword argument
rather than a positional one.  In this case you should write:

{% 'path.to.some_view' arg1=v1 arg2=v2 %}

checkout https://docs.djangoproject.com/en/dev/ref/templates/builtins/

The url tag calls reverse() which has to be called with:

reverse(name, args=list, kwargs=dictionary)

I got this error a few times when url was trying to make the kwargs
dictionary.

Best regards,
Marcin

Hello, you could take a look at the classic cgi concept. It is the base 
on which all wsgi,fastcgi and the rest of the family stand.


You have the webserver who accepts a request, the web server passes the 
request to a program (of any language) through an interface ( cgi,wsgi 
etc) the program returns through the same interface a response, the 
webserver returns the response to the world.


A simple idea with a lot of consequences...

Class Based CreateView with foreign key question

[Jason Arnst-Goodrich]

I'm having trouble wrapping my head around how to use generic class based 
views properly when it comes to creating objects associated with already 
created objects.

The concept here is adding File objects to a Case object.

The url pattern would be something like:

url(r'^case/(?P\d+)/add/$', AddFileToCase.as_view(), {}, 'file-add')


So going to case/1/add would prompt the user with a form to add a file to 
case with pk = 1.

The following code below is doing what I want but I'm not sure it's the 
best way to handle it. I feel the documentation to be very lacking in this 
area.

class AddFileToCase(CreateView):
model = File
form_class = FileForm #all of the file fields exposed except for the 
foreign key relationship field to Case

def dispatch(self, request, *args, **kwargs):
self.case = Case.objects.get(pk=self.kwargs['pk'])
return super(AddFileToCase, self).dispatch(request, *args, **kwargs)


def form_valid(self, form):
form.instance.case= self.case
return super(AddFileToCase, self).form_valid(form)

Re: How does it all work

[Russell Keith-Magee]

Hi Nafiul,

One place to start would be to read the WSGI specification. WSGI is the
interface between your web server (say, Apache) and Python as a language.
The WSGI spec - also known as PEP 333 - gives a brief overview before it
gets into the fine details. However, one of the advantages of WSGI as an
interface is that there aren't actually that many fine details anyway --
for such a significant specification, it's remarkably readable.

http://www.python.org/dev/peps/pep-0333/

This will show you the interaction between web server and code that a
website developer would need to write; from there, it's a matter of looking
at what tasks the website developer needs to do often, and finding
abstractions and APIs to make that job easier. That's where Django, and
it's libraries for URL routing, database interaction, form processing and
so on comes in. If you try and write a non-trivial website to the "bare
metal" of WSGI, you'll very quickly see what Django (or any other web
framework, for that matter) is providing for you.

Yours,
Russ Magee %-)

I think.. I found what you are looking 
for: http://www.djangobook.com/en/2.0/chapter01.html
Under the heading "The MVC Design Pattern"..
there is a nice example of a simple CGI script using python (no django).

first of all, do the tutorial, don't try to go further until you're
somewhat comfortable with the concepts there. You'll get the feel of
the most basic and powerful django tools are: models, forms, and the
admin site. I don't remember if it's been updated to use class-based
views, but you should take a look at them too, it'll be easier for you
to navigate 3rd party code, and it's becoming the standard, plus
generic views are another of the time-saving goodies.

Then go to #django in irc.freenode.net, there's lot of very patient
and helpful people there

Re: How does it all work

[Gamesbrainiac]

@Eraldo: Thanks for the reply. I've read that part of the Django book, but
it does little to explain how Django itself works, because it uses WSGI not
CGI. After this excursion, I plan to see how Django handles connections and
such, so I'll be diving into the Django libraries.

Thanks for this, I appreciate it.

is possible to store a value of a field in a proxy model

[carlos]

Hi
is possible to store a value of a field in a proxy model

I explain how models are

class Model1(models.Model):
title = models.Charfield(blabla)

class Model2(models.Model):
name = models.CharField(blabla)
fk_field = models.FK(Model1)

and then important thing

class ItemModel(Model1)
class Meta:
proxy = True

def save(self, *args, **kwargs):

# I would like to do something like that is possible?
#what would be the right thing to do?

*self.title = Model2.name*

super(ItemModel, self).save(*args, **kwargs)

will be possible to do that?? someone could explain if possible!! yes or
not :/
