Forms: Set default value

[Wiiboy]

Hi,
I'm defining a form model, and I have a choice field.  I have the
values in order, and I want one value (in the middle of the values in
order) to be the default.  How do I do that?

Passing initial= anything doesn't work.

Lost Comments moving from test to production

[goodwinb]

I have a project that uses django.contrib.comments wrapped by
mptt_comments.  It was working fine on my test server.  In moving the
project to a production server I have missed a setting somewhere and
lost Comments.

When I hit the page that will contain comments I get "Caught an
exception while rendering: operator does not exist: text = integer
LINE 1: ...ent_ptr_id") WHERE ("django_comments"."object_pk" = 1  AND
T...".

When I go to /admin I see mptt_comments but not comments.  When I
start the db I see the comments table being created.  My settings.py
includes INSTALLED_APPS = ( ... 'django.contrib.comments',...).  My
urls.py contains '#(r'^comments/', include
('django.contrib.comments.urls')),'  I am using Python 2.6 and Django
1.1 beta.

Does anyone have any kind hints to look to see where I have gone wrong
in the settings?

syncdb and #10706

[Kenneth Gonsalves]

hi,

I find that syncdb fails silently to create tables for apps that give the 
misleading error message described in #10706. I cannot find a ticket for that. 
Should one be filed, or have I missed it?

Re: dict objects are unhashable in admin... in this a bug?

[Some Guy]

admin.py is here --> http://pastebin.com/m23760293 ... stack trace is
here -> http://pastebin.com/m971fc89

It's fairly vanilla. I also had a similar error from the {%doctools%}
tag on change_list page.  SInce it was not essential I changed it to a
comment tag.  Things work ok after that, but I need the ability to
edit users :-)

Right now I'm using 1.1 beta 1 django, apache2, and sqlite3

I saw something similar in trac but it was closed with "works for me"

ANN: RuPy '09 Conference

[Jakub P. Nowak]

RuPy 2009 :: Strongly Dynamic Conference

Poznan, Poland
November 7-8, 2009

:: Call for speakers

RuPy is a conference about dynamically typed programming languages.
Held for the first time in April 2007 it gathered enthusiasts
from Poland and other countries.

The idea behind the conference is to liven up the
community and make these technologies more popular in Europe.

The first conference was a middle-sized one but came out as
a huge success. We believe it was a great experience for both
attendees and speakers.

RuPy 2009 committee is looking for speakers willing to present
a Python, Ruby, Groovy or any other related subject.
If you have an interesting talk in mind go ahead and submit a
talk proposal. The talk proposal should include a talk title,
brief introduction and your short resume/biography.

To our invited speakers we offer free accommodation, full
board and possibility to interact with a very lively IT community.
You are also free to participate in all the extra events -
'Geek party' always turns out great!

You can also support us by linking to our site and informing
all your friends about the event and the possibility to submit
a talk proposal.

Potential speakers should submit an abstract using the following
form:

https://spreadsheets.google.com/viewform?formkey=dEFEYndsQWR2TGFzRFpzcU9IbFlCT2c6MA..

by September 30th, 2009 for consideration.

If you have any special presentation needs, let us know.

For more details check our site:

Re: Converting django models to google app engine models

[Matteo Rosati]

Hello friend,
maybe you can consider using the Goole App Engine helper for Django.

http://code.google.com/p/google-app-engine-django/

when you download the necessary files, read the README file and read how to
deploy a pre existing django application in google AE without modifying your
files (except for the settings); this is explained in "Installing the helper
into an existing project" in the README file!

i hope this helps you!

bye,
Matteo

The slug will only be automatically populated when you are adding records
from the admin.  Any other method of entry will not have the slug field
automatically populated.

Slug Field

[Sonal Breed]

Hi all,

I am little confused about the working of slug fields.
I have a model:
class Story(models.Model):
slug = models.SlugField(unique_for_date = 'date_created',
help_text="suggested values automatically generated
from title"
title = models.CharField(max_length=50, blank=False)
story = models.CharField(max_length=500, blank=False)

In admin.py
class StoryAdmin(admin.ModelAdmin):
prepopulated_fields = {"slug": ("title",)}

admin.site.register(Story, StoryAdmin)

Now, should I expect the slug field to get automatically populated
with the value of title, each time an entry is saved. What is the
expected behaviour of slug? Currently, I cannot see the value of title
in slug field in admin site.

Can anybody throw some light on this?

Thanks in advance,
Sonal.

Re: Question regarding post_save signal and ManyToMany field objects

[Ryan K]

Alex,

So I have my Menus that contain links and a Link can be in multiple
Menus. Are you saying make an explicit model like:

class MenuLinks(models.Model):
menu = models.ForeignKey(Menu)
link = models. ForeignKey(Link)

?

Basically what I am doing is making an enhanced flatpages app called
staticpages. I want my client to have full control over the page's
content, menus associated with a page as well as links in the menu..
Here is my signals.py:

http://pastebin.com/m3c333dd

If I modify it to use the above table and connect to its post_save
signal, is my solution worth it? I use signals to generate an XHTML
menu and cache it in my database. I do this in a thread. Someone said
don't use threads. What is the consensus on that?

Cheers,
Ryan

Basic AJAX (was: Re: multi applications)

Use jQuery -- it'll automate most of it.

Here are two simple samples. Both are in the $(document).ready()  
function. Once you use jQuery for about three minutes, you'll know  
what that is.

This does a GET request to get a user's current balance.
It then writes the balance (returned as JSON by the view)
into the HTML div with the id current_balance.

$.get("/balance_json/{{ch.slug}}", {}, function (data){
$('#current_balance').html("$" + data.balance);
}, 'json');


This does a POST to submit a form to send an SMS message. The view  
also returns
JSON in this case, (created from a Python dictionary), which will  
have a key of 'success'
with a value of the success message, or a key of 'failure' with an  
error message in it.

 $("#sms_form").submit(function(event){
 event.preventDefault();  // stop the form from submitting and  
refreshing the page
 var data = $("#sms_form").serialize()

 // now send the data to the server via AJAX
 $.post("/patient/{{ch.slug}}/sms/", data, function(resp){
 if(resp.success) {
 $("#messages").html("" + resp.success + "");
 $("#success-message").animate({ backgroundColor:  
"#E6EFC2" }, 2000);
 update_activity();
 } else if (resp.fail) {
 $("#messages").html("" + resp.fail + "");
 $("#fail-message").animate({ backgroundColor:  
"#fbe3e4" }, 2000);
 }
 }, "json");
 });

I don't know if there are are super-special Django tools to do AJAX,  
but as it's JavaScript and Django's Python, I doubt it.

The most useful things in Django are simplejson and safestring (both  
in django.utils). You'll need simplejson to easily dump a dictionary  
into a JSON string to pass back to JavaScript, and you'll need  
safestring to "mark_safe" JSON strings you're going to pass via the  
context to be rendered within the templates. Otherwise they'll be  
escaped automatically for your protection.

Re: multi applications

Thank you for the explanation.
This helps me very much.

You mentions about handling the smaller apps on the page with AJAX. Is there
any basic functionality to do this from Django Framework?
Or do you have any ajax lib/framework as preference?

You can use the django model cache:
from django.db.models.loading import cache

cache.get_apps() will returns the models.py modules for all your apps.

There are several different aspects to what you are asking for and  
describing. The first part is showing all the apps within one page,  
and that's just a matter of a well-formatted CSS/HTML template. This  
template may (should?) include smaller templates (for each section).

Ultimately your page will be called by a single URL, so you'll receive  
the entire request in one place. From there, you will have to decide  
how to handle the contexts. Look into the RequestContext class. The  
things you need to display on all pages, regardless of what the "main"  
view is at the moment, can be moved over there to avoid clutter.

The "main" content could be handled in the view called directly by  
urls.py, and the rest can be inherited from the context dictionary  
keys coming from your request contexts.

Also, you'll probably want/need to handle all the smaller apps on the  
page with AJAX, because you won't want to refresh the entire page for  
updating the microblog, etc. And since you're referring to FaceBook,  
they even do most of the processing of actions in the "main" section  
with AJAX, just to have a smoother user experience.

These are certainly vague answers. If this isn't what you're asking  
for, please provide more detail.

problem with redirect

[Petry]

Hello Guys,

I'm having some trouble using redirect in my application

after making a request, rather than redirect to the domain + the url
it is sending to the IP address of the domain, I capture the request
through the Firefox addon HTTP_HEADERS:


#request# GET https://www.ucs.br/favicon.ico
#request# GET https://www.ucs.br/site/administracao/banners/1/edicao/
#request# POST https://www.ucs.br/site/administracao/banners/1/edicao/
POST /site/administracao/banners/1/edicao/ titulo=Matr%C3%ADculas+On-
line+%3Cbr%2F%3EPer%C3%ADodo+2009%2F4=http%3A%2F%2Fwww.ucs.br
%2Fucs%2Fgraduacao%2Fmatriculas_online
%2Fmatricula_online_exibicao_0=14%2F05%2F2009_exibicao_1=18%3A00%3A47_exibicao_0=15%2F06%2F2009_exibicao_1=22%3A00%3A00=R
#request# GET http://200.160.128.111:8005/site/administracao/banners/1/
#request# GET 
https://ucsvirtual.ucs.br/login/?next=/site/administracao/banners/1/

note that I am using https, and the field, when I, in the redirect
using the reverse:

post_save_redirect = reverse ( 'apps.banners.views.exibe', args =
[banner_id])

he sends it to the address above, (ip and http)

multi applications

[sjtirtha]

Hi,

I'm looking for documentation, which describes how to build a web
application which includes many other applications.
For example like Facebook, it has following applications on the first
screen:
1. On the left side is dynamic menu
2. In the middle is the microblogging
3. On the right side on the top is Request block
4. On the right side in the middle is Highlights

How can I build a web application like this? I was thinking to have a main
application which has a template that includes all other applications.
But how can I set the context specific for every templates of the included
applications?

regards,

Steve

Set user = request.user in your view.

A slightly more "automatic" way of doing it would be
to override the save method of your model, but I think
you'd still have to pass the user instance into it.

How to store user

Hi everyone.

I use django.views.generic.create_update.create_object to allow users
to post new entries on my site.
How can I make model automatically save the user currently logged in?
Model like
class MyModel(Model):
user = ForeignKey(User)

Creating Model with ManyToMany relationship from PyAMF & Flex

[Jesse Warden]

n00b here.  I'd like to create a complex Model from a Flex Object (basically
decoded JSON).  I've created a Model successfully already, but am unsure how
to do this with the multiple Models that have ManyToMany relationships with
each other.
This works:

def create_power(request, powerObj):
try:
p = Power()
p.name = powerObj.name
p.level = powerObj.level
p.save()
...


However, I'd like to create the other models too.  Psuedo structure:

class PowerSource(models.Model):
label = models.CharField(max_length=200)
power = models.ManyToManyField(Power)

What would the code look like... maybe like this?

ps = PowerSource()
ps.label = powerObj.powerSource.label;
ps.power = p;
ps.save()

Thanks if you can help!

This is easy, I loaded the page through urllib and write it to a

create a snippet for this ;)

Re: newbie question information about js

We need more information. Are you calling myfunct() via an AJAX call?  
I don't see a request in the argument list, but is that because you  
left it out, or is this not a "view" function (receives request and  
returns a response)?

Your function executes server-side, and JavaScript (obviously)  
executes client-side. Python can't do the alert box, but it can:

1. Render a template containing the JavaScript.
2. Pass the JavaScript text into a templatt, via the Context.
3. Return a JSON value via AJAX to the template's JavaScript (you have  
to bind the handler in the JavaScript, preferably using jQuery for  
ease-of-use) that passes the message to be used for the alert.

I hope this helps. If not, please send more relevant detail. Pretend  
you're explaining the problem to someone who has no idea what you're  
talking about, because we don't.

Re: Django admin for PHP?

[diogobaeder]

I've had a great experience with Symfony, with which I worked for
about 9 months, and I can tell it's a great framework, and also fairly
easy to create admin interfaces. Of course, not as easy as Django, as
you said, but...

I also tried CakePHP for a time, but I didn't like the means it used
to generate these kind of interfaces, and it's too "Railsy" for me -
maybe the Cake creators made it to use a Rails-like development
process in a non-Ruby-supporting environment, but if you like Rails
and can use it, just go for it -. Generating scaffolds for every app
isn't as easy, for me, as Symfony's or Django's ways of creating
admins.

Use the Chrome Browser to see the source code generated by Django, and
then you can follow the css of your page.

Than, you can see if this is pointing to the rigth place ;)

This is a security feature of the browser so that you don't accidentally
upload an arbitrary file to the server without knowing it. I don't know of a
way to get around it, nor would I hope there is one. This is the case for
all browsers and all internet forms. The only thing I can offer is to
separate your uploading from the rest of the form so you can save the image
even if someone types in a wrong phone number.

Hope that helps,

Michael

How to add a new button near to "Add a new article"

[Fred Chevitarese]

Hello!
I´m needing to add a button near to the button to add another object.
For example, there´s a app called Articles...
When i´m in the admin interface, i can see all the articles that i
have in the database in a grid. In the top, i have a button to add a
new article.
So, i want to put another button near to this, to call another view
for example. I can put a "link" in the grid that calls the desired
view, but, i really need to put it near to this button.

Can anyone help ?

Copy your app to site-packages folder and see if that works. If you dont

Image Field Validation

[kevinski]

Hello,

I am using 3 image fields in my model form. When I browse for images
and submit, the images are uploaded with no problem. When my form does
not validate, error messages appear for invalid fields and correct
fields stay in tact, however my image paths disappear and I am
required to browse for them again and again until the form finally
validates. Anyone ever experience a similar problem? Any idea what I
am missing?

I've searched and searched and haven't found info on this. Please let
me know if there is any code I could offer and I will post.

Thanks!!!

IMHO yes. It will save you a lot of hassles like this and will allow you to
add methods to clean and validate the data when you find that you need it.
The Form class was built to help you at this kind of thing.

To fix this chunk of code, get rid of the try: except statement. There is an
error occurring in you code after the try statement, and you have a catch
all there, so you are bound not to se it happen. That doesn't really help in
debugging,

Hope that helps,

Michael

Re: Saving Data To Your DB. Simple?

[Lakshman Prasad]

> It runs OK (no errors) but doesn't save a single thing
 It has to run without errors because you have enclosed the whole thing
in try.

 You have to coerce the record_id and user_id into int before assigning
to the model fields, for it to save.

Saving Data To Your DB. Simple?

[The Danny Bos]

Heya, am trying to simply save 3 values to a database, without using
Forms.

In the Template:




Rate This: {% for n in numbers %}{{ n }}{% endfor %}



In the View:

from mysite.rating.models import Rating
def critics_rating(request):
try:
record_id = request.POST['record_id']
user_id = request.POST['user_id']
rating_val = request.POST['rating']

rating = Rating()
rating.rating = rating_val
rating.item = record_id
rating.writer = user_id
rating.save()

return HttpResponseRedirect('/')
except:
pass
obj = Record.objects.get(id=record)
return render_to_response('record/detail.html', {'object_detail':
obj}, context_instance=RequestContext(request))

It runs OK (no errors) but doesn't save a single thing, also it goes
back to the 'detail.html' page fine, but when you hit reload, it sends
the data again. Again, not saving.

Any ideas what's wrong with this?
I've done a lot of searching but all people seem to use the Forms
widget, I was thinking as this is only three fields I'd skip that.
Silly?

Take a look at PIP and it's requirement file system, which I think for
python packages is a good solution.  If you have OS level dependencies (such
as the stuff GIS relies on) you'll probably need to see what tools your
packages manager offers.

Re: Has anything changed with Sagepay/protx apart from the name?

To answer the original post:

Sagepay AFAIK is a rebrand as sage have owned protx for a while now.

Nothing should have changed apart from names of products.

Deployment dilemma

[Rama Vadakattu]

I have a django project with N number of dependencies to other
packages.
Now i want to deploy the project on production server?

As of now iam doing this.
1.Move the django project to production server.
2.install the dependencies on production server similar to that of the
way i have done on local system.

Is it the right approach?
i feel reinstalling dependencies again on production server is
tedious.

i would like to know how everyone  is dealing with the above problem.

Re: Reading data from database tied to another Django project?

[Benjamin Kreeger]

I was using PostgreSQL at first, but then I found information about
reading data across databases only with MySQL, so I'm using MySQL for
the time being.

Now, I don't have a database set for P1 yet because it's just
displaying reStructuredText files; if I were to set up that site to
access P2's database (in P1's settings.py file), would I be able to
(eek) do raw SQL to get the data to display the way I want? Or would
there be an easier way to do that WITHOUT raw SQL, and WITHOUT
duplicating that model declared on P2?

django-admin.py complains about missing DJANGO_SETTINGS_MODULE

[Nate Reed]

The admin tool is complaining about this environment variable, but I've
never had this problem before on this box.  I'm not sure what's changed
since the last time I used it.

I tried specifying the path:

$ django-admin.py syncdb --settings=mysite.settings
Error: Could not import settings 'mysite.settings' (Is it on sys.path? Does
it have syntax errors?): No module named mysite.settings

What's the fix for this (short of modifying django-admin.py to add my
project to the python import path)?

I'm using django 1.0 (from SVN).

There may be a better way, but why not just pass a range in the context?

context = {'numbers': range(1,51)}

Then you can do:

The best way now to get this feature is to use an intermediary model which
obviously get's its own signals.  Additionally I've been working on
refactoring m2ms to always use an intermediary model, thus signals would
always be sent.

One option would be to use a generic relation:

A little history may help explain why this has been open for so long.

Historically (i.e., when dinosaurs roamed the Django source code)
signals were _very_ expensive - even signals that had no listeners. As
a result, there was a lot of resistance to adding new signals. Given
the performance cost, the decision was made to live without m2m
signals.

Just prior to v1.0, the signal framework was updated, which made
signals much faster. However, in an attempt to actually hit the
deadline for getting 1.0 out the door, adding new signals wasn't on
the plan.

Adding new signals was discussed as a possible feature for v1.1 (see
the features page [1]); however, nobody took charge of getting it
done, and other development priorities took over. The feature deadline
arrived before anyone got around to implementing (and integrating) the
change.

When the v1.2 development cycle starts, I'm sure this will be back on
the schedule again.

Count from 1 to 50

[The Danny Bos]

Is there a way to create a simple list using Django to go from 1 to
50.
Eg:

1, 2, 3, 4, 5 ... 49, 50

I figured it'd be easy, but I can't get it.
I tried ...

{% for i = 1 in 10 %}
  {{ i }},
{% endfor %}

No go.

No, the other way around. The interview table wouldn't have anything  
in it to point to the illustrator or author. The Author and  
Illustrator models would each have a ManyToMany field defined to the  
Interview model. The "related_name" property of this field will give  
you an easy way, when using an Interview model, to pull its related  
Author or Illustrator objects. When you start with an Interview  
object, you'll need to do something like check to see if:   
len(this_interview.author.all()) > 0

So the Author and Illustrator tables would stay as is.
How would the Interview table talk to both of those tables at once, to
allow me to assign an interview to who I'm interviewing. Whether it's
an Illustrator, Author or even down the track a Publisher.

Like so?

class Interview(models.Model):
body = models.TextField()
publication_date = models.DateField(auto_now=True)

interview_subject = ...

class Meta:
ordering = ['publication_date']

I think you'd just have the interview table without any foreign keys,  
then add a ManyToMany to each of your Author and Illustrator models.

You would still, of course, be able to start with your interview table  
and get the authors or illustrators, if necessary in your app. It  
might be handy to set the related_name property of this field for easy  
reference from your Interview model.

AJAX is a good solution.

When the user hits the submit button, have JavaScript (I recommend  
jQuery) cancel the actual page submission and instead send the POST  
request.

If I understand what you're saying, you want to do something for some  
number of checkboxes on the page. In which case, you could write a  
function which accepts a value (e-mail address, maybe?), then write a  
JavaScript loop to iterate through the checkboxes, count the number to  
process, then call your function repeatedly in the loop, updating a  
status bar based on how many have been completed so far.

As for the status bar, check docs.jquery.com or the docs for jQueryUI  
to see if there's a pre-made one. I'm pretty sure there is. Worst  
case, you get a thin graphic and dynamically change its width to a  
percentage of the div it's in or something.

I don't believe you can put the  on the same line as the
SetHandler.  If that is literally what has really been placed in the apache
config file that might be the problem: try putting a line break before the
.

Re: I need to get psycopg2 installed on Mac OS X 10.5

[Shawn Milochik]

I had the same terrors. Unfortunately I didn't document exactly how I  
did it, but my best recollection is that this will work:

1. Update setuptools: sudo easy_install -U setuptools

2. Download and unzip the tarball for psycopg2.

3. Edit the config file for psycopg2 as directed on other Web sites,
paying special attention to the pg_config argument (make sure it  
points to the right place in your /Library/PostgreSQL folder).

4. Run: sudo python setup.py install

Re: Style sheet not working after shifting from desktop to laptop

[Lakshman Prasad]

Either you have a wrong directory pointed to, in your settings.py file for
static media; or you haven't configured django to serve them.

You need to define MEDIA_ROOT and MEDIA_URL in the settings.py
appropriately. Once you have done that, you can setup django to serve those
during development, by using the following pattern in the urls.py.

urlpatterns += patterns('django.views.static',
(r'^app/(?P.*)$', 'serve', { 'document_root':
settings.DIRNAME,
'show_indexes': True }),
)

Re: Complex form for a newbie with ImageField and ForeignField

[Lakshman Prasad]

You could replace in the view:

if form_upload.is_valid():
  form_upload.save()


# with this:

if form_upload.is_valid():
  form_upload.user = request.user
  form_upload.save()


You may also want to not display the user field in the form. You can do it
by defining an 'exclude' Meta class attribute for the ModelForm, as done
below. I believe you can also hide a field in the form by marking it
"editable=False" in its model's field definition.

class FormUpload(forms.ModelForm):

class Meta:
model = ModelName
exclude = ('user',)

DjangoCon 09 Recording (was: Re: DjangoCon '09)

[Shawn Milochik]

I've been listening to a lot of podcasts from PyCon 09, and for the  
most part the audio is horrible to the point of not being listenable.

Are there any plans in place to do any recording at DjangoCon yet?  
It's vital that the actual speaker is miked. If someone is recording,  
even from a few feet away, the sound is crap.

If there's no plan in place, then I'd be interested in helping out. I  
can bring at least one mic, and record at least the sessions I'm in,  
if it's okay with the organizers. Also, if PyCon 09 is any indicator,  
most speakers have no experience talking on-mic, so I'd give them a  
few tips. One of which is to repeat a question before answering it,  
because often the questioner doesn't make it onto the recording.

I was also thinking about getting another portable recorder, like the  
Zoom H-2, for recording events. If we can even get one of those onto  
each podium, I think we could have awesome sound quality.

So, if there's already something planned, please let me know. If not,  
let's see if we can hack something together so that everyone can  
benefit from an awesome event.

You do not mention that you did anything to copy your settings.py and
urls.py file from your desktop to laptop.  (These are not in the application
directory you mention copying.)  Since your application generally works, I'd
guess you did do something to copy these files, but it sounds like (since
you say the href value in the returned html is correct) the urlpattern for
the static server to serve the css file is not set up correctly.

Database Model Layout Advice

[The Danny Bos]

Hey there, this may not be appropriate, but I'm building in Django so
here goes ...

I'm creating an Interviews app/table in my Django 'Books' (test)
project. Just wrapping my head around it before I start on my music
based website ... Anyway,

For my 'Interview' table, how would I assign an interview to an
'Author' or an 'Illustrator', as they both have separate tables
themselves. Know what I mean? Seems crazy to choose either the Author
from the list OR the Illustrator, how would I assign an Interview to
either?

Here's the layout for 'Interview':

class Interview(models.Model):
body = models.TextField()
publication_date = models.DateField(auto_now=True)

author = models.ForeignKey('books.Author')
illustrator = models.ForeignKey('books.Illustrator')

class Meta:
ordering = ['publication_date']

Complex form for a newbie with ImageField and ForeignField

[djangonoob]

I'm using django 1.02, Ubuntu 9.04, python 2.6.2

Issue: I am creating a simple application that allows users to upload
images.
I'm using the User from django.contrib.auth.models to manage my users.
For the image class, i have a ForeignKey to the user and a ImageField
to store my images

My application works perfectly, except that:
when the user uploads images, the images will be linked to the user
himself.
However, on the upload form, i have a option selection box where all
the usernames are selectable.

How do i fix the views.py, models.py such that the user can only
upload images using
his own username and at the same time, without having to select his
username from the dropdown selection box?

The following is my code:
http://dpaste.com/66944/

Thank you in advance.

was not closed

[Robert]

Hi,

My web hosting company get the curious error message above when
configuring httpd.conf.

I'm trying to deploy a djangoproject on a public server. The
webhosting company isn't familiar with python and django. They don't
give access to httpd.conf to the clients. It's a cpanel type of
webhosting company.

Apache is configured with mod_python on the server.
So far I have simply uploaded the newest Django-release to a folder on
the server. As far as I know this is possible when you put Django on
your PythonPath.

I have asked the web hosting company to add the following to the
httpd.conf file. It should be pretty similar to the documentation:


SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mysite.settings
PythonOption django.root /mysite
PythonDebug On
PythonPath "['/home/account/django', '/home/account/www'] +
sys.path"


The first part in the PythonPath is the path to Django from my
document root.  The second part is the path to my public project.


SetHandler None 

The last segment is the path to the Django media files. The
documentation says that you should give the "url root" to the
mediafiles. I thought that "url root" was the same as the path from my
document root, thus a quite lengthy path.

I guess the error message " was not closed" came up in the
apache error log. I have googled the message but haven't been able to
find anything useful.

Initially I thought it could be a case of a missing bracket or
something, but the code seems fine.

Would you please look through my code and give me your opinion?

Thanks. Appreciate it.

Robert

I need to get psycopg2 installed on Mac OS X 10.5

[Kevin]

I need to get psycopg2 installed on Mac OS X 10.5

I have read every install guide I could find and I still do not have
it working. I have developer tools installed. I am running MacPython
2.6.2 and PostgreSQL 8.4 downloaded from 
http://www.enterprisedb.com/products/pgdownload.do

On my production machine (Debian) I did a simple atp-get and it
worked. Why is it so much harder on Mac OS X?  I am very near ripping
my hair out because I have wasted too much time and I do not
understand why psycopg2 does not work on my machine.

Below are my notes from three attempts to install psycopg2.  I have
read other threads that suggest installing Python, PostgreSQL, and
psycopg2 from MacPorts.  I do not want to use MacPorts.  I do not see
why I need to use a completely different installation of Python to use
a simple database driver.



For my first attempt I followed the instructions listed here:
http://jasonism.org/weblog/2008/nov/06/getting-psycopg2-work-mac-os-x-leopard/
It told me to add these lines to setup.cfg:

include_dirs=/Library/PostgreSQL/8.3/include
library_dirs=/Library/PostgreSQL/8.3/lib

I then ran python setup.py build and got this error:

$ python setup.py build

===


For my next attempt I followed the instructions listed here:
http://blog.jonypawks.net/2008/06/20/installing-psycopg2-on-os-x/
It told me to run this:

PATH=$PATH:/Library/PostgresPlus/8.3/bin/ sudo easy_install psycopg2

This resulted in this error: (I substituted "8.4" for "8.3" because my
version of PostgreSQL is newer)

For my third attempt I installed the binary of psycopg2 from
http://pythonmac.org/packages/py25-fat/index.html
I thought it worked, but when I tried to import the module in the
interpreter I got this error:

>>> import psycopg2
Traceback (most recent call last):
  File "", line 1, in 
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/

  Reason: image not found





What the hell do I need to do to get psycopg2 working with my

Has anything changed with Sagepay/protx apart from the name?

[Kip Parker]

I noticed whilst researching which payment gateway to use that Protx
has become Sagepay. Anyone know if they've just changed the name (so
that the Protx payment module still works OK) or if they've changed
the product at all (so the Protx module doesn't)?

OK, think what happens when you return from that view: you go back to
the calling view. Does that return anything?

Re: .views._CheckLogin.__call__ didn't return an HttpResponse object

[Ryan K]

I'm not really sure I understand your question but you don't need to
jump to another view...you just need to pass the relevant objects to
the mailer function and then "return render_to_response(...)." If the
mailer function is already in another view, refactor the code and
create a non view function that handles mail.

Cheers,
Ryan

Ok, a simple question:
Are there any possibilities to call from current view another view.
For instance you have a large view and in the middle of it you need to
perform THE SAME actions which are already defined in def foo
(request,username).
Of course, you can copy the contents of foo(request,username) view
into your big view, but I don't think it's a correct solution.

Re: Question regarding post_save signal and ManyToMany field objects

[Ryan K]

Yea...it would be so elegant too! Here is a "bug" filing:

years

I understand that your really getting what you asked for, just the
instance of the model you just saved but to me (and it seems you and a
lot of other people), intuition leads people to write code that drives
them nuts because its not really "post_transaction."

To be a little more explicit, perhaps your view code contains:

render_to_response('template.html",{},RequestContextInstance)

as opposed to

return render_to_response(...)

Both abbrev and name live on the DirectoryType model, not the
DirectoryAdmin one, so you can't refer to self.name in the __unicode__
method of DirectoryAdmin. I'm not at all sure how you wanted this to
work, since there's no direct relationship between directoryadmin and
directorytype.

ok my bad, I didn't realize that the structure of the project had

and of course at the root of the directory there is no settings file,
instead I have to go to the ultimate revision.

I think you have misunderstood how foreign key fields work. The  model
that declares a ForeignKey field is the *many* side of the 1-to-many
relationship - ie the way you have it, each Directory has a single
DirectoryType, and a DirectoryType has multiple Directories.

If this is right, the misunderstanding is how you then set each side
of the relationship. From a Directory, you just do dir.directoryType =
x where x is a DirectoryType instance. But that does mean your loop
doesn't make sense.

However if you do want mulitple directorytypes for each directory, the
foreignkey field needs to live on the directorytype, and you would
then do dir.directorytype_set.add(x).

apache + mod_python + svn

[Bastien]

Hi,

I know this is slightly off topic but such a common situation that I
guess somebody has already run into it.

I have just deployed my project on a remote debian server with apache
and mod_python following the documentation and it just works very
well.

Now I need to use subversion to keep updating the project so I
installed it via 'apt-get install subversion' and 'apt-get install
libapache2-svn'. That's where I made a mistake because I'm only using
svn via ssh so I did not need that apache mod.

What happened is that when installing libapache2-svn my apache config
files were modified and I was asked to restart the server and suddenly
I was granted with a mod_python error instead of my home page.

If anybody can spot what is wrong or knows what files have been
changed so I can change them back that would be of great help. Here is
the error message if is of any relevance:

MOD_PYTHON ERROR

ProcessId:  23452
Interpreter:'78.XX.XX.XX' <- my public IP

ServerName: '78.XX.XX.XX'
DocumentRoot:   '/var/www/'

URI:'/'
Location:   '/'
Directory:  None
Filename:   '/var/www/'
PathInfo:   ''

Phase:  'PythonHandler'
Handler:'django.core.handlers.modpython'

ImportError: Could not import settings 'settings' (Is it on sys.path?
Does it have syntax errors?): No module named settings

One last thing the path of the project has changed but I updated it in
the apache2/sites-available/default and restarted apache.

Thank you,
Bastien

PS. I was using {{ object_id }} because this worked in the

It seems the TinyMCE Javascript has not been rendered correctly.

Maybe the compressor could not find all files?

Could you show the generated Javascript?

Re: html file (UTF-8) generated from template does not displayed correctly using MS internet explorer 6.0

[Eugene Mirotin]

Most probably your html is incorrect, but FF is smart enough to handle
it.
Try the following:
* switch to the Strict XHTML instead of Transitional (as the latter is
not recommended)
* create a static HTML file (replace the remplate logic with some
dummy values) with the desired layout
* validate it using the w3c validator

I expect your file to have some validation errors. After you fix them,
update the template according to your fixes.

Re: url as folder path possible?

[Eugene Mirotin]

The problem is still unclear.
Do you want to handle the path example.com/some/path/ and route it to
some view that would get the 'some/path' as argument?
If so,
* write the url conf like r'^([\w_\/]+)/$', handle_path
* write the handle_path(request, path) view
* in view split the pass by slashes
* determine the object based on the path (using some getattr calls on
modules or objects)
* call the desired methods on the obtained object
