Re: public html?
By the way, that is the way to get django's development server to serve
up you files, and not necessarily the best way to go when you want to
deploy your site.
Your best bet is some sort of webserver like apache or lighttpd

Javascript and same origin policy
Hello, I'm having a problem with TinyMCE integration, but let me first describe how my current development setup looks like. Directory structure is like this: project.com |-project |--all the django stuff |-static |--static stuff including javascript and some php The thing is that the whole project.com is served by apache because of php in static dir which is there for TinyMCE file browser - TinyBrowser. The address for apache virtual host is http://localhost and I use it only for static files, for serving Django files I use Django development server in "project" directory and address http://localhost:8000. And I think that this is a problem. Whenever TinyMCE wants to open a new popup window, it's blank and I think that "same origin policy for javascript" [1] is reason for this. I've read that this should be easily solved by using document.domain javascript statement but it somehow doesn't work for me. Did anyone have similar problems or has any idea how to solve it?

Re: Tips for reading The Django Book in light of Django 1.0
I do keep reading the Django book + DjangoDocs of the same topic at the moment. As first one is easier to read, the second one represents 1.0 version better. Also always check the DjangoBook's comment's - most of deprecated features are mentioned there and updated with more recent ones. Anyway, can't wait for 2nd edition of DjangoBook :) BTW, has anyone tried Python Web Development with Django http://is.gd/7Tni, which, it seems, offers the examples suitable for 1.0? good luck, J On Nov 17, 11:08 pm, Ian Fitzpatrick <[EMAIL PROTECTED]> wrote: > Hi All, > > I read through the Django Book just as the book went 1.0 a little less > than a year ago, but as these things go I got sidetracked and never > got to work on any substantial Django projects.

If I get you right, you're not running the dev server process on your own machine ? If so, it looks like your familiarity with web servers is lacking one important point: 127.0.0.1 is the loopback IP address - IOW, it's an IP address that connect one machine *to itself* !-).

Tips for reading The Django Book in light of Django 1.0
Hi All, I read through the Django Book just as the book went 1.0 a little less than a year ago, but as these things go I got sidetracked and never got to work on any substantial Django projects. Having forgotten a lot of what I learned, I'm thinking to work my way back through this book, but I know a lot has changed with the advent of Django 1.0. Can anyone recommend areas of The Django Book to skip over, or point out areas that are potentially irrelevant/misleading given we are now at Django 1.0? I am a stubborn pursuer of dead ends, so am trying to save myself some grief here.

Re: Can't access the development server
I think the issue is that your server is only listening for incoming calls from the local (host) machine. The 127.0.0.1 is a kind of magic number that just means in IP-speak 'this machine'. Try running it as python manage.py runserver www.yourhost.yourdomain.com:8000 (suitably replaced by your domain name of course). This will make it listen for connections from other machines as well. If you are using the 8000 port number, your browser should connect to it when you type in http://www.yourhost.yourdomain.com If the 8000 port is already taken (by some other server eg. apache running), you should get an error message. Then try with another port, e.g. python manage.py runserver www.yourhost.yourdomain.com:8900 and type something like http://www.yourhost.yourdomain.com:8900 into your browser. The 3000 port number you mention is almost certainly wrong. There is nothing super magic about ports: they are just a number, but client and server need to use the same...

Can't access the development server
Hi, I'm completely new to python and Django, although fairly familiar with programming and web servers in general. I'm struggling to get Django up and running, at the moment, and I'd be really grateful if someone could help. I'm following this tutorial, after having successfully installed Django: http://docs.djangoproject.com/en/dev/intro/tutorial01 I start the development server using: python manage.py runserver which seems to work ok: Validating models... 0 errors found Django version 1.1 pre-alpha SVN-9479, using settings 'prototype.settings' Development server is running at http://127.0.0.1:8000/ Quit the server with CONTROL-C. In fact, on that server, I can telnet to the development server fine. However, if I try to access it in my browser, nothing happens. The access doesn't show up on the server output and the browser fails to connect at all. I've tried starting it on different ports, with no success. I am able to access the thing on port 3000, although at the moment I'm not quite sure what this is... As far as I know there are no firewalls between me and the server (it's a shared hosting server with Site5). I'm assuming that when I try to connect to port 8000 this will go directly to the development server and apache settings etc should be irrelevant? How about python settings? Is it possible that I've got something misconfigured that would cause this behaviour? Any more information I can provide? Thanks in advance!

Others already gave you practical answers, so this will be mostly a
more general ('conceptual' ?) advice: don't mix heterogenous data
(objects, whatever) in a list. If you have a compelling reason (ie :
ordering) to have heterogenous data, wrap them all in a same 'meta'
data structure.
David's answer is one possible solution, but it still requires 'type'
testing on each item of the collection. The (potential) problem with
this solution is that each new 'type' will require a modification of
the template. A more OO solution is to use another level of
indirection, ie: make your view return a list of {data:whatever,
template:'path/to/specifictemplate'} dict, so the template's loop
doesn't have to make any test:
{% for stuff in mylist %}
{% with stuff.data as object %}
{% include stuff.template %}
{% endwith %}
{% endfor %}
This might be overkill for your concrete use case, and (like any
solution based on indirection FWIW) has some impact on performances,
but it's often worth the price when it comes to maintainance.
My 2 cents...

Your best bet would be to define a method on the Project model that
returns a snippet of HTML with the link and text. You need to set
allow_tags=True.
def projectowner_link(self):
return u'%s' %
(self.projectowner.id, self.projectowner.name)
projectowner_link.allow_tags = True
list_display = ['name', ..., 'projectowner_link']

Re: Setting Up Django on Vista and Creating a Database

You can look at the treebeard benchmarks in http://django-treebeard.googlecode.com/svn/docs/index.html#module-tbbench I'll take as an example the results of reading branches in postgresql 8.3 in unordered trees: - Nested sets:5840ms - Materialized Path: 7132ms - Adjacency List:50682ms So as you can see, your approach (adjacency list) is by far the slowest.

Re: psycopg2 Visual Studio installation error on XP
Hi DJ, Psycopg2 has a C extension wrapped by Python. That C extension must be compiled with the same compiler used to compile the Python compiler itself. This is not a Django issue, this is a psycopg issue. You should ask for assistance on the psycopg mailing list, they'll be better able to help you. You should also look around for pre-compiled binaries of psycopg2 for Windows, as the packagers will have taken this compiler mismatch issue into account. ---Peter On 11/17/08, dj <[EMAIL PROTECTED]> wrote: > > Hello All, > > I am django novice and i am very, very ,very, very green. > > I am trying to setup the PostgresSQL database with the psycopg2 > library.

Running multiple sites
Noob question here. My web host allows one long running process per account for the plan I am on. So I can run one django process. The setup is using fastcgi if that matters (we don't have control over this--we are assigned a fastcgi port or something and this is the command we use to run our django process: django-admin.py runfcgi method=threaded host=127.0.0.1 port= pidfile=$PIDFILE, and I export DJANGO_SETTINGS_MODULE in my environment). So, I am wondering if I can run multiple django websites given this setup? I have read a little about the django.contrib.sites app, but am not clear if this would help in my situation. Or do I have to have one instance of "django-admin.py" running per website? Thanks for any clarification. -Chris PS I found this after some googling, but not sure it is still relevant/applicable.

Re: automatically save latitude and longitude of the address.
I can see several causes here why you're not getting the desired
result. The biggest one is you declare fnclatitude as taking a single
argument, called location - but when you call the function from your
save() method you're passing no arguments to it.
Second, you're returning element 3 (which is longitude) and calling it latitude.
There are two possible ways to rewrite the code to work:
1: (bring the call to Google into the save() method, which is
perfectly acceptable if this is the only model that requires
geocoding)
Code at: http://dpaste.com/91472/
2: (keep it seperate, which is more useful if other models in your
system will require geocoding. I'd definitely rename the function
though because it's doing more than just returning latitude at that
point.)
Code at: http://dpaste.com/91483/

required checkboxes issue
I have a problem with one of my forms in regard to a series of
checkboxes. They are displaying properly on the page with the right
values in the checkboxes. I have this set to REQUIRED in my form.
However, whether I check one box, or check them all, I still get this
message:
"Select a valid choice. That choice is not one of the available
choices."
My forms.py code for this form field is as follows:
Designations_Choices = (
('1','1'),
('2','2'),
('3','3'),
('4','4'),
)
Designations = forms.ChoiceField
(choices=Designations_Choices,required=True, label = "Gift
Designations", widget=forms.CheckboxSelectMultiple(attrs=
{'class':'designations'}))
Any ideas why this won't validate correctly even when 1/4 or 4/4 boxes
are selected?

Without looking at any docs or code, it seems you have a mismatch in the
number of values expected by the form (one) and what will be returned by the
widget (multiple). Are you sure you don't really want to be using a
MultipleChoiceField?

link to ForeignKey in Admin's change list page
Hi
maybe this is trivial, but i can't find a way to get it (and from what
i can see it seems not possible):
my model:
class Project(models.Model):
name = models.CharField('name', max_length=255)
#relationship
projectowner = models.ForeignKey(Person)
in admin.py:
class ProjectAdmin(admin.ModelAdmin):
model = Project
list_display = ['name', ..., 'projectowner']
list_display_links = ['name']
list_filter = ['name', 'projectowner']
list_display_links will put a link at the 'name' field to the
Project's page, like this one:
http://localhost:8000/admin/projects/project/1/
is there a way to the the same result for the foreign key?
I would like that at the 'projectowner' field there would be a link
like this one:
http://localhost:8000/admin/projects/person/2/
thanks!

Re: Frustration with custom Inline forms
Thank you thank you thank you! I knew I was doing something simple wrong. :) I've been enjoying my experience using Django so far, but one thing I have noticed is that the error messages (or in this case lack of error messages) can be frustrating. It sometimes takes me quite a while to figure out what caused an exception especially if there are no line numbers of my own code. In this case, it's actually the Python syntax and I'm not sure what Django could do if your syntax is wrong, but I sure spent a while tracking this down Cheers, Ben --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

You could create a relatively simple custom template tag that knows how to render an element from your list. The templatetag is Python code, so you would be able to test for the type of the element being rendered. -RD --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

This is normal behaviour -- the built-in model serializers traverse
only over local fields of the model and not over foreign keys.
> Is this possible?
Yes. In two ways:
1. If you are willing to write your own serializer, take a look at the
SERIALIZATION_MODULES setting and the interface you will need to
implement. To implement the interface, you would normally extend the
abstract base class: django.core.serializers.Serializer defined in
django/core/serializers/base.py
2. Create a list of dictionaries for your result set. Where each list
element represents one row of data and each row contains a dictionary
of the fields you are interested in. Then use
django.utils.simplejson.dumps to convert that list to a JSON string.

What about making it a list of tuples, and including a type?
{'articles': [('single', ),
('multiple', {1: , 2: }),
('single', )]}
Then you could just do a {% for type, article in articles %}, and have
a conditional on the type.

The only thing I can see in your code that might cause problems is the
value for exclude:
exclude = ('a55_id')
This is not what you think it is. It's not a single-element tuple. It
is actually a single string, which will be treated as if it were a
list of characters ie ['a', '5', '5', '_', 'i', 'd']. Naturally, the
admin doesn't recognise this as a field, so won't exclude it.
I think what you meant was
exclude = ('a55_id',)
- note the extra comma, which is how you define a single-element
tuple.
There's no reason you can't have custom forms in an inline formset - I
do this all the time, using very similar code to the above.

Passing values to template
Hey guys, I have a news application that I would like some help with. My view generates a list with objects mixed with dictionaries with two objects. Then in my template, I want to loop through this list and output each value. However, when it encounters a dictionary in the list I want it to loop through it separately with a different formatting. This is an example of a dict passed to my template: http://dpaste.com/91439/ So the question is: how do I check (in the template) if the object that is being run in the for loop is a dictionary, so that I in turn can run a for loop on it?

And, IMO, the vast majority of foreign key use cases do benefit from an auto cascading delete. For the specific Links/Groups example, personally I'd just do it with a many to many relation. It's entirely feasible that in the future, Links will need the ability to associate itself to multiple groups. For now, I'd just limit a link to one group via some custom validation. -- --- David Zhou [EMAIL PROTECTED] --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Serializing models to JSON
Hi,
In my application I'm trying to serialize the following model to json:
class Node(models.Model):
name = models.CharField(db_column="NAME",
max_length=30,
db_index=True)
description = models.CharField(db_column="DESCRIPTION",
db_index=True,
max_length=255)
registrationDate=models.DateField(db_column="REGISTRATION_DATE",
db_index=True)
parentNodeObject = models.ForeignKey("self", db_column="PARENT",
related_name="parent_fk")
rootNodeObject= models.ForeignKey("self", db_column="ROOT",
related_name="root_fk")
Before I serialize the instances to json I retreived all the nodes:
models.Node.objects.select_related
('parentNodeObject','rootNodeObject')
The problem is that for all the parentNodeObjects and rootNodeObjects
retrieved from DB, in the json string appears only the model's id.
I don't know if this is normal or not but I'd like to have access to
all the properties of all the objects retrieved,
even if the final json string is huge.
Is this possible?
I'll appreciate any thoughts regarding this subject.
Thank you,
srn

Re: avoid cascade delete

Funny that you ask this question, because I just spent two days undoing the Django cascading delete on my end. If you look at the delete() method in the Django code, it only makes three calls. The first two gather a list of all the objects that Django wants to delete. Basically, I wrote a new delete() method that iterates through those objects, finds all the references to the object that you want to delete and sets them to null. It then saves them. After this, you need to run those first two lines again to regather the objects you want to delete (this time, only the one object should appear), and then you can finally delete them. I would argue this is more desireable than using clear() explicitly, because you don't have to know anything about your models with this method. Any time you have to remember to set a certain relationship to null, you are bound to forget about another relationship between your objects, and you'll get cascading delete on something you didn't expect, and you won't have even noticed that it happened! -- Randy Barlow http://electronsweatshop.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Frustration with custom Inline forms
There's a problem with the exclude statements above, you've got tuple-
trouble, missing trailing commas:
exclude = ('a55_id') should be ('a55_id',) or ['a55_id']
easy mistake, search for "tuple" in this group and you'll see you have
company.

I'd recommend going through a Python tutorial if you don't know any of this: www.diveintopython.org is a great one.

Sessions
Hi,
I'm trying to work with the session object in my application but it
doesn't work as expected.
So in my settings.py I have:
MIDDLEWARE_CLASSES = (
'django.middleware.gzip.GZipMiddleware',
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.middleware.doc.XViewMiddleware',
'django.middleware.transaction.TransactionMiddleware',
)
TEMPLATE_CONTEXT_PROCESSORS = (
"django.core.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n",
"django.core.context_processors.media",
"django.core.context_processors.request",
)
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'mySite',
)
With this I can access the 'user' object in my templates if for
example I try authenticating a user in,
but not some other variables I set mannualy with request.session
['aVariable']='aValue'.
I use this for rendering : render_to_response('template.html',
context_instance=RequestContext(request)).
And in my templates: {{ request.session.aVariable }}
And there's some other thing that's not clear to me:
>From the above configuration I understand that django stores the
sessions in the database so if I want
to use file storage I'll have to add this to my settings.py :
SESSION_ENGINE = 'django.contrib.sessions.backends.file'
SESSION_COOKIE_AGE = 7200
SESSION_COOKIE_NAME = 'acookie'
SESSION_FILE_PATH = '/temp/django'
but then all the "session" thing stops working.
Is there something that I should enable or disable from my settings
file?
Thank you,
srn

geodjango importing existing data - pointfields
I have a legacy database that consists of a number of addresses with pre-geocoded WKT points. I'm trying to import these directly into a GeoDjango setup - postgres db, either by csv or psql csv copy - doesn't matter which. First problem is I get this error 'new row for relation "site_locations" violates check constraint "enforce_srid_point" - if I delete that constraint it imports but then I get a whole heap of new problems displaying that data on a map (tranforming SRID etc to work on a commercial map provider). I'm guessing Geodjango tags the srid to the pointfield when saving a new location in the admin, which must mean my syntax for the WKT imports is missing that vital info to make it all work sweetly: 1,1,'Edinburgh Castle','Edinburgh','Lothian','EH1 2NG','POINT (-3.20277400 55.95415500)' I've tried multiple variations on the POINT syntax (GeomFromText etc...) but no joy.

Frustration with custom Inline forms
I'm trying to customize the inline forms of a model that are displayed
when I'm editing it's parent, but I can't get anything to work! Can
someone help? First, here are my models:
class T22Pais(models.Model):
a22_id = models.AutoField(primary_key=True)
a22_nome_1 = models.CharField("Nome Responsavel
#1",max_length=255)
class T55Visitas(models.Model):
a55_id = models.IntegerField(primary_key=True)
a55_visita_agendada = models.DateTimeField(null=True, blank=True)
a22 = models.ForeignKey(T22Pais,verbose_name="Pais")
The documentation says "The InlineModelAdmin class is a subclass of
ModelAdmin so it inherits all the same functionality as well as some
of its own," so first I tried this:
class T22PaisAdmin(admin.ModelAdmin):
inlines = [T55VisitasInline]
class T55VisitasInline(admin.StackedInline):
exclude = ('a55_id')
model = T55Visitas
but nothing changes. I tried a couple variations of the name without
and without quotes and adding the model hierarchy exclude=
('T55Visitas.a55_id') but nothing worked.
Then I noticed that the documentation refers to form and formset
fields in InlineModelAdmin. The documentation isn't very clear how to
use these, but I tried the following things and nothing had any
effect: the inline form was always rendered with all of its fields:
class T55VisitasInlineForm(forms.ModelForm):
class Meta:
model = T55Visitas
exclude = ('a55_id')
class T55VisitasInline(admin.StackedInline):
model = T55Visitas
form = T55VisitasInlineForm
tried adding a formset:
class T55VisitasInline(admin.StackedInline):
model = T55Visitas
form = T55VisitasInlineForm
formset = inlineformset_factory(
T22Pais,
T55Visitas,
exclude = ('a55_id')
)
adding the same form back into the formset even though I'm already
setting T55VisitasInline.form, but no dice. :(
class T55VisitasInline(admin.StackedInline):
model = T55Visitas
form = T55VisitasInlineForm
formset = inlineformset_factory(
T22Pais,
T55Visitas,
form = T55VisitasInlineForm,
exclude = ('a55_id')
)
How can I get this to work??? Grrr... Ideally, I'd like to have a
fully custom inline form using "fieldsets," but for now I'll settle
for just hiding fields.
Cheers,
Ben

Because something cannot be included as part of a many-to-many relation until is has a primary key value -- which means it has to be saved first. So the new Ticket instance must be saved and *then* the many-to-many saving happens. That is, after Ticket.save() has returned. At some point in the future we'll most likely add a signal that you can use to process things when a many-to-many is updated, but at the moment, the way to do this is to manually trigger the emailing wherever the many-to-many is updated (in your view code). It's not a perfect solution, but it works. Regards, Malcolm --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

500 leaves is really nothing for the database. If you want to do
anything with that size tree, you can easily just use a simple nested
hierarchy like this, pull all the rows back into Python and work with
them there. Particularly since you only have three levels in the tree:
queries on name or parent__name or parent__parent__name are as bad as
it's going to get (thereby meaning you can often filter to just the
branches you want).
Things like the modified pre-order tree traversal data structures just
speed up the retrieval so that you don't have to retrieve all the rows
and become useful for large trees, or trees with deep (and unknown)
levels of nesting. So start with something simple, by all means. It's
fun, it's a learning experience, it will probably work very well in
practice. And if you later decide to switch to one of the other
packages, it won't take a lot of changes to move things to the new model
(it will take some changes, but it's not really that difficult).

Malcolm

I am glad to hear that the naive way could possibly fit my 3-levels tree, or at least that it deserves a try. I'll have some benchmarks as you suggest.

A "decorator" is just a function (or any other callable) that takes a
function as argument and returns a function (or any other callable).
The @decorator syntax is only syntactic sugar.
In most cases, the returned function is just a wrapper around the
decorated one, and this is obviously what you want:
def anonymous_only(view):
# 'view' is the view function to decorate
# since we decorate views, we know the first parameter
# is always going to be the current request
#
# '_wrapper' is the function that will be used instead
# of 'view'.
def _wrapper(request, *args, **kw):
# here we can access the request object and
# either redirect or call 'view'
if request.user.is_authenticated():
return HttpResponseRedirect('/page_for_logged_in_user')
return view(request, *args, **kw)
# this part is not mandatory, but it may help debugging
_wrapper.__name__ = view.__name___
_wrapper.__doc__ = view.__doc__
# and of course we need to return our _wrapper so
# it replaces 'view'
return _wrapper
Note that this example assume you always want to redirect to the same
page if the user is logged in, which might not be the case. Things get
a bit more complicated if you want your decorator to takes the
redirection url as param, since we'll then need one more indirection,
IOW : a function that takes an url and returns a function that takes a
function and returns a 'wrapper':
def anonymous_only(redirect_to):
def deco(view):
def _wrapper(request, *args, **kw):
if request.user.is_authenticated():
return HttpResponseRedirect(redirect_to)
return view(request, *args, **kw)
_wrapper.__name__ = view.__name___
_wrapper.__doc__ = view.__doc__
return _wrapper
return deco
Then you use it that way:
@anonymous_only('/page_for_logged_in_user')
def register(request):
# code here

Take a look at the content of django.contrib.auth.decorators module
(the _CheckLogin class, a call in user_passes_test
and login_required).

That's the canonical solution when using the adjacency list pattern,
yes.

If you are really confident that your hierarchy will never grow deeper
than three levels, the above solution might be good enough. But it's
still less efficient than the materialized path or the nested sets
patterns when it comes to reading a whole branch.

Well... I'm not sure there's any clearcut answer here. If you have
enough time, you may want to do a couple benchmarks on representative
data and use cases.
My 2 cents...

How to access the request object in a decorator
Hello,
I wanted to redirect a logged in user if he access certain page. For
example i do not want the user to access registration page if he is
logged in.
A simple way to do this is:
def register(request):
if request.user.is_authenticated():
return HttpResponseRedirect('/
some_nice_page_for_logged_in_user')
...
The problem is i have lot of pages that only anonymous user can
access. So i wanted to write a decorator so that i can do something
like that
@anonymous_only
def register(request):

Re: unchecked checkboxes not accessed through request.POST['check_name']
As far as i remember according to the HTML specs the unchecked values
are not sent with form post.
So you can use some logic in your server side code to deduce the
unchecked values. (Since you render them in the first place so may be
you have a list of items from database)
or if you really want to sent them from HTML form use some javascript
to set those uncheck values in a hidden field.
Hope this helps.

Items tree in Django
Hi everybody out there! :-)
I have to cope with a few hundreds item tree/hierarchy in my Django
project. Specifically, I'll have 500 hundreds leaves in a 3-levels
tree with a dozen branches.
I won't need much writing over this tree, I'll just need to read it
and show data in a drop down menu.
I've been told to use django-treebeard or django-mptt to speed up
things, but I wrote down a first draft on my own:
class Node(models.Model):
name = models.CharField(max_length=50)
parent = models.ForeignKey('self')
class Product(models.Model):
name = models.CharField(max_length=50)
parent = models.ForeignKey(Node)
[some more info here]
The point is, how can I create the root of my tree? Should I add some
"blank=True, null=True" properties to my Node model? So to have:
class Node(models.Model):
name = models.CharField(max_length=50)
parent = models.ForeignKey('self', blank=True, null=True)
And then consider the "null-parented" node as the root one?
Does my code make any sense? Do you think it will turn out as too slow
for my hierarchy? Should I better rely on django-treebeard or
django-mptt?
Any help appreciated, thank you so much!
Regards,

Re: Apache Segmentation Fault on succesful authentication
Can you try building mod_wsgi instead and see if it picks up the correct library? If it doesn't work, post the output from running 'configure' script and running 'make' for mod_wsgi. I trust mod_wsgi build process more than I do mod_python.

automatically save latitude and longitude of the address.
HI All,
How can I add automatically latitude and longitude of the physical address.
for exp if, fnclatitude('Chennai') returns latitude and longitude of
chenai.
Please help
This is my model (models.py)
def fnclatitude(location):
key = settings.GOOGLE_KEY
output = "csv"
location = urllib.quote_plus(location)
request = "http://maps.google.com/maps/geo?q=%s=%s=%s; %
(location, output, key)
data = urllib.urlopen(request).read()
dlist = data.split(',')
if dlist[0] == '200':
return "%s" % (dlist[3])
#return "%s, %s" % (dlist[2], dlist[3])
else:
return ''
class Business(models.Model):
physicaladdr_street1 = models.CharField("Street 1", max_length=25)
modified_date = models.DateTimeField()
latitude = models.DecimalField(max_digits=11, decimal_places=6,
null=True, blank=True)
longitude = models.DecimalField(max_digits=11, decimal_places=6,
null=True, blank=True)
def save(self, force_insert=False, force_update=False):
self.modified_date = datetime.datetime.now()
self.latitude = fnclatitude()
# here I need to automatically add latitude and longitude of the
physical address.
# for exp if, fnclatitude('Chennai') returns latitude and
longitude of chenai.
super(Business, self).save(force_insert, force_update)

Re: In forms, how add dynamic initial values out of reach for clients?
I've already read that and can't get the first one working: instance = Instance(required_field='value') form = InstanceForm(request.POST, instance=instance) new_instance = form.save() In my case, shouldn't it look like this: user = request.user discussion = Discussion.objects.get(pk=discussion_pk) form = CommentForm(request.POST, user=user, discussion=discussion) form = form.save() Or am I wrong? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
