Re: Unsafe to continue Django session unencrypted? (i.e. login with HTTPS then drop to HTTP after that?)
They should be worried. But the session id is not the credentials. So it is probably argued that it is secure enough. However, you should google firesheep. That is a browser add-on which can hijack non-SSL sessions over unsecured wireless.

Moving Away from if/else Template Logic
Hello All,
I'm try to get away from doing if/else in a template:
{% if x.message|regtest == "True" %}
do something cool
{% else %}
do something less cool
{% endif %}
given this template filter:
@register.filter(name='regtest')
def regtest(value):
regex = re.compile(r'^\*\*(?P.*)\*\*')
m = regex.match(value)
if m != None:
return "True"
return "False"
I would like to move to something like this in the template:
{{ x.message|regtest }}
given this template filter:
def regtest(value):
regex = re.compile(r'^\*\*(?P.*)\*\*')
m = regex.match(value)
if m != None: return "%s"%value
else: return value
However, the html tags returned from the filter becomes part of the
element's text value instead of tags. So that's not working.
I'm sure there's way better ways to side-step ugly if/else logic in
the templates. What types of things can people recommend for a Django
new guy.

import with django-batchimport and only insert if record doesn't exist else update based on foreignkey reference.
I'm trying to run an import and in my identity fields I'm referencing a foreignkey field. The excel file holds the name of the brand and this field seems to be ignored when the import happens. My theory was that perhaps it's because it's not mapped and in fact it's probably matching the brand_name against the brand_id. Wondering if you've run into this? class Ingredient(models.Model): 'identity_fields':['name', 'brand_name'], ... name = models.CharField(max_length=60) brand_name = models.ForeignKey(Brand) ... The end goal is to see if the name and the brand match then to and not insert. thanks -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: storing django object into javascript array
Hello,
I was given the following solution for storing a django object in a
javascript variable
//SOLUTION BEGINS HERE
1. Use a loop in the template:
var map_schools = [{% for school in city.school_set.all %}"{{
school|escapejs }}"{% if not forloop.last %},{% endif %}{% endfor %}];
You'll notice a couple of things there:
- there is a "for" loop there, to iterate over all of the schools in the
result set
- the quotes are present in the template, to make sure that the school
names are strings in the JavaScript
- there is a test after every string to see if a "," is needed as a
separator (some javascript implementations are not very forgiving if you put
a comma after the last element)
- Every school name is passed through the "escapejs" filter, to avoid
breaking out of the string.
//SOLUTION ENDS
Now, I was wondering how I can store the {{ school|escapejs }} into a
javascript array, and use the data inside school as if it were an array
element, like map_schools[1], map_schools[3] etc
Thanks
regards,
JK

Re: Problem in accepting values from a form in a template . How to debug this ?
Page Not Found or 404, basically doesn't have any relation with template of
form.
Just check if you have the URL that you are trying to hit in urls.py, as 404
happens when the URL you are trying to access is not configured or not
available on your webapp.

Re: Django admin report
If all you need translating is README.rst, here goes:
Django Admin Report
Django Admin Report is a small django application that allows for easy
exporting of PDF reports through the admin interface.
Dependencies
-Pisa (http://www.xhtml2pdf.com/)
Installation
1. Download the application
2. Add the package "report" to your path.
Usage
- In your application's admin.py, import the following 'action' like so:
from report.actions import report_generic
- Also in admin.py, in your model's ModelAdmin specify a variable called
"list_report" that should contain an iterable with the model attributes that
should appear on the report, e.g.
list_report = ('some_attribute', 'other_attribute', )
- Finally, make sure you also add the aforementioned 'action' to your
ModelAdmin's list of actions, like so:
actions = [report_generic, ]

I should add that some screenshots would go a long way!

I have Apache in front of my Django app. It forces login pages to use HTTPS but then forces rest of pages to only use HTTP. Is client browser sending sensitive login or session info in the clear when I am not using HTTPS? My nonencrypted pages don't present or ask for sensitive info. The only danger would be if sensitive info is being sent behind the scenes I didn't program myself. cs -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Authentication in API (REST)
Neznez,
The authentication problem is one that has never really been solved to
any general level of satisfaction for REST APIs, since the connection
should be stateless. For HTTP authentication there is either HTTPS +
Basic or Digest. HTTPS + Basic considered to be the easiest to
implement and the most secure but running a server with SSL is not the
most trivial of tasks and there are issues for clients and the problems
of managing certificates, etc. etc.
For a Java based REST API I used the scheme used by Amazon web services
where the request is signed using a secret key and then authenticated on
the server which worked rather well and was resistant against lots of
different types of attack. You can find out more at
http://docs.amazonwebservices.com/AmazonS3/latest/dev/index.html?RESTAuthentication.html.
However I am not sure what level of support you can find in django.
Stuart
Hi all, I'm newbie in Django, and I started to build my own API. I
know that there is Piston or Django REST framework, but I want to
learn API from scratch. What I want to know is, how to make my HTTP
Response (View) is perform authentication before can be accessed, or
we can make it have to throw username and password to access the HTTP
Response?
My code is very simple, like this one:
def test_api_view(request, whatever):
#
# do things
#
return HttpResponse(serializers.serialize("json", mydictionary),
mimetype='application/json')
Thank you.

Re: How to catch and log exceptions?
Yes, you can access the traceback from the middleware.
Just call logger.exception() instead of something like logger.debug()
and you'll get the output in your log.
Here's my middleware:
import logging
logger = logging.getLogger(__name__)
class RequestExceptionMiddleware(object):
"""
Log any exceptions that happen in a view.
"""
def process_exception(self, request, exception):
logger.exception('view broke')
return None

How to catch and log exceptions?
I want to catch any exceptions thrown in my views (or anywhere else, I suppose) and log a full stack trace. I know I can write middleware which implements process_exception(), but that just gets me the naked exception object, not a full stack dump. I'm assuming that by the time my process_exception() method gets called, it's too late to call sys.exc_info(). Or is it? I can't use the default DEBUG mechanism which displays the stack trace in the browser. For one thing, I want the information in the log. For another, most of my routes are AJAX calls, so there's nowhere to display it. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: 2 projects based on the same codebase
Benedict, One solution I tried was project franchising, http://www.huyng.com/archives/franchising-running-multiple-sites-from-one-django-codebase-2/394/ The idea was to have a core site that was customized for different deployments. The idea had a lot of appeal but I quickly ran into issues with the limited ability for customization and the codebases began to diverge quickly. Until you can get to the stage where you can factor out the common parts (not always easy) into reusable apps I would second the suggestion for separate projects. It seems like needless duplication (which it is to some extent) but you easily avoid compatibility issues and then both projects are free to take whatever path works best. Regards, Stuart MacKay Lisbon, Portugal Hi, I developed a calltracking for our team and now, another team is interested to have their own calltracking. The best way to seem to deal with a project that is the same from the start, is to makea new virtualenv and "git clone" the codebase. The new project might slightly differ in the futur. I have a development machine where I maintain the code, then "git push" the code to a server. On the production machine, i "git pull" the code. This all works but what if the 2nd team wants slight changes, changes that my team may not want? 2 virtualenv's based on the same code might not be the best option in this case. Do I create a new repository for the code of the other project ? I feels like the best way to go ahead. However, this would mean that I need to maintain 2 projects that are and probably will remain very similar. How would i transfer code changes from 1 repository to the other? Patches? Thanks for any insight, or links to documentation that deal with this kind of setup and sorry in advance for going OT. Regards, Benedict Hi, thanks for the info. I will use a seperate repository for the 2nd project. Regards, Benedict -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Userprofile, signal and admin inline edit.
The issue seems to come from the fact that the order of operations when you create the user looks like this: 1) Django admin saves the new User 2) post_save on User is triggered, and User's profile is created 3) Django admin saves the UserProfile... but it already exists, and an integrity error is raised I'm currently looking into a solution to this as well, and will let you know what I find.

Re: Get MAC from diferent fields
Hi there, Django is just a Python package.

https://docs.djangoproject.com/en/1.3/ref/contrib/contenttypes/#django.contrib.contenttypes.models.ContentTypeManager.get_for_model
get_for_model takes a model type (eg User) or a model instance. It
does not take a string.

A simple example of a type of form you should always use GET for is a search form.

To extract the mac addresses you could use a regex like:

Re: GET vs POST for read-only views
Hi Shawn- There is a consensus in the web development community at large -- the HTTP Spec itself touches on it, and the W3C has released a few supporting statements as well. http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html This is the HTTP 1.1 spec, section 9, which defines the difference between the various verbs, including GET and POST, in terms of idempotence. And this helps clarify: http://www.w3.org/2001/tag/doc/whenToUseGet-20040321 For your use case, I would definitely use GET. The user may wish to bookmark the report, for example, or send it to a colleague. Searches and such should always use GET, unless there's a truly compelling reason not to. POST should only be used for things that change stuff on the server... a contact form, a form that creates something in a database, etc...

Error 'str' object has no attribute '_meta' . How to debug ?
I want to create a model that brings user_id of the user_auth table as
foreign key , layer_id from layer table(defined by me) as also a
foreign key . Combine both to form a primary key . and have another
integer called perm .
My model looks like this
from django.contrib.gis.db import models
from django.contrib.auth.models import User
from django.contrib.contenttypes.models import ContentType
from maps.models import Sdr_Layer
class PermiLayer(models.Model):
user = models.ForeignKey(User)
table =
models.ForeignKey(ContentType,related_name='custom_permission_set')
permi = models.IntegerField()
My view logic is this
if form.is_valid():
data = form.cleaned_data
rad1=form.cleaned_data['radio1']
rad2=form.cleaned_data['radio2']
user=User.objects.get(username = data['user'])
perm = PermiLayer()
perm.user = user
perm.table = user_type =
ContentType.objects.get_for_model('maps_parking')
perm.permi = rad1 + rad2
perm.save()
This gives me the error that I have mentioned above . How do I change
the model and the view to remove the error ?

computer_id = models.CharField("Direccion Mac 3",max_length=192,

multi-page, non-sequential, dynamic forms with serialization/deserialization
Hi all, I looked into Django for a specific task, but before I get too deep I want to make sure it is possible. We already have a site that does what we need (http://depts.washington.edu/uwcl/matrix/customize/ matrix.cgi), but it is written entirely in custom, proprietary code, and it is getting difficult to maintain. We need the following features: * large, multi-page form (too many fields to fit on one page) * dynamic forms (ability to add more fields on demand) * non-sequential entry (users can jump back and forth filling it in) * serialization (the serialized output is sent to our existing backend, or the user can download it) * deserialization (the user can upload a file that fills in field values) We don't currently use a database backend, as longterm storage of entered data is not a high priority. It mostly takes the form input, produces output, and is done. It seems Form Wizards allow multi-page forms, but are geared towards sequential entry (fill out page 1, submit, fill out page 2, etc). Is it possible to jump from one subpage to another, allowing data from each page to affect other pages? I also found some tutorials on serialization, but I didn't see much on deserializing a file back to form field values. Is this possible?

Well i do have entries of the kind this :
{
"pk": 47,
"model": "contenttypes.contenttype",
"fields": {
"model": "user",
"name": "user",
"app_label": "auth"
}
},

Django Admin: Add text at runtime next to a field
I want to add a text next to a field of the django admin interface. The warning needs to created at runtime inside a python method. I know python and the django ORM well, but I don't know how to get the text next the field. The text should be a warning. Raising ValidationError in clean() is not a solution, since the user can't edit the page any more. It should be just a warning message. One solution would be, to create a custom admin form (easy), and subclass the field, to create a custom field. That's not difficult, but I guess there is a better solution.

Yes, fine. Just discard the exception and traceback, so no one will
ever get a chance to know what happened.
duh :(
