Login over HTTPS

[Jani Tiainen]

I'm trying to get Django to make authentication (namely username + 
password) to be transferred over HTTPS. But rest of the site is still on 
plain old HTTP.

How this can be done? I've very little success and google didn't gave 
much of help either.

I'm using Apache 2.2 with mod_wsgi and I've total control over my 
webserver config.

For mod_wsgi, you first need to verify whether it is saying you are
running under HTTPS in the first place. To do this you need to know
the value of wsgi.url_scheme as passed in WSGI request environment.

One way of doing that is to use a WSGI middleware wrapper to capture
request details. See first example in:

  
http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Tracking_Request_and_Response

If wsgi.url_scheme isn't 'https', then your Apache configuration is
wrong, or you are using another front end web server which is actually
handling HTTPS and you aren't conveying that fact through to backend
Apache and doing appropriate configuration changes to reflect that.

If 'wsgi.url_scheme' is correct, then it is a Django issue, or more
likely how you are using Django or how you have configured it for
location of media resources etc.

Post output or request details from that first code example in
referenced document.

Putting django based site on HTTPS

[zweb]

I want to serve whole of my site on HTTPS.
But HttpResponseRedirect  is sending to http by default.

Any way to tell django that it should use https and not http

I am using mod_python on one site and mod_wsgi on another. Both need
to go to HTTPS

Re: View count ignore auto_now

[TheIvIaxx]

yeah i think thats what i will have to do, but you end up treating the
view count as a separate object.  Or i can just take the auto_now off
and just do my own date updates on the save method.  just thought
there may have been a built in way to do it :)

You /may/ be able to do it with a OneToOne relation instead of a
field.

(Just an idea, I haven't tested it).

Re: Discovering the ip/port in use by runserver

Other than something like this, obviously, which works, but is a bit
fragile & certainly not very nice:

def get_server_address_by_stack_inspection():

if (s[0].f_code.co_filename.endswith("django/core/

session question

[webbo]

Hi all,

It's great to join this great Django place !!

I am trying to make session work, but it doesn't work as I think.

I want my 2 pages able to share the same variables that I stored in
session.

Thanks first for paying attention on this post.



Please give me some suggestion as bellow:

I want to use anonymous sessions for my 2 functions:  list_user and
list_device

1. I have a dropdown box called "group" for both functions.

2. Once I changed group value in either one page, the group value will
be stored in session.

3. For example:
If people click on group dropdown box and change value to "GROUP1"
in list_device or list_user page, then
the value of group drop-down box of both list_user and list_device
should be changed to 'GROUP1'

4. It works on Firefox if I press F5 to refresh the page.  Sometimes
the value is updated by clicking refresh button many times.  Is any
problem relate to my browser setting?

5. It never works on IE, and IE generate so many session_keys in
django_session.

Looks like your final line is not properly indented - should be lined

View count ignore auto_now

[TheIvIaxx]

Hello, I have a simple page model that has created and modified fields
with auto_add and auto_now set to True.  I'd like to keep track of the
number of views per page so i added a views field to the model.
However if i increment the views and save, then the modified gets
changed.  This trivializes the modified field as it will be updated
every time someone views the page.  Is there a way to update a single
field only with the ORM or will i have to do a SQL query?

Thanks

Runserver uses your development database, test uses an initially empty test
database.  You've got primary key id values hardcoded in your test data. You
don't say anything about how you are ensuring that the test database has
exactly the same data, including primary key values, as your development
one.  Are you doing something that would make this assumption that the
development and test databases are identical valid?  Because it's not, in
general.

Unit testing form validation issue

[Chris Allen]

Anyone have any experience with forms (ModelMultipleChoice fields and
foreignkey'd choice fields) not validating properly in a unit test but
just fine in the runserver?

Passing the same request.POST data to the unit test as I am in the
runserver and live instance, which I verified via the debugger.

Using a data dict instead of the actual request object.

the is_valid() fails for two different forms on three fields (1 for
one, 2 for the other). All three fields are choice fields.

Dump of various relevant info is below.

I appreciate any help anyone can offer.

Thanks for your time,
Chris

Re: Definitive solution for foreignkey filtering in Admin

It seems that editing the values in self.fields yields rendering
errors:

Caught an exception while rendering: 'QuerySet' object has no
attribute 'label'

It appears that the values are not vanilla QuerySets... I've been
browsing the code again, and I really don't know what the values are.
It's fairly convoluted with that __metaclass__ business in there.  Do
we know what kind of datatype is in self.fields?  When the template
iterates the Form object, it's wrapping it as a BoundField, but
clearly something's messing up during that iteration.  I'm afraid I
don't know much about how the mechanics of this area work in the
Python code.

Any more pointers would be great.  Other than this speedbump, I think
this will do nicely.

Re: Adding button to admin change form

[Mikhail Korobov]

You should override change_form.html template and save it as

/your_project/templates/admin/your_app/change_form.html

or

/your_project/templates/admin/your_app/your_model/change_form.html

Re: Admin interface is doing nothing

[Mikhail Korobov]

It is very likely that your urls.py is wrong. Re-check if admin urls
are included exactly as in documentation example: "(r'^admin/', include
(admin.site.urls))", without any wildcards.

Admin interface is doing nothing

[M.]

Hi,

I've installed the Admin interface, but the interface is unresponsive.
If click on USERS, the page refreshes itself and appends auth/user/ to
the URL. If I click it again, it appends it again, but I still remain
on the same page. I am using Python 2.6 and Ubuntu.

Thanks,
Martynas

DATE_FORMAT

[Sumanth]

Hi all,

Currently the DATE_FORMAT is used only for admin pages.

Can I use similar setting where all my date objects are displayed in
the same way in templates , without having to apply humanize on
templates not using date function in templates?

Thanks

Re: ModelForm - how to post primary key to update existing record?

[robinne]

I pass Member to the template with something like this...(I don't have
my code here with me)

VIEW
...
if not post
  member = MemberModel(pk=1)
  return render_to_response('mytemplate.html', {'Member':member})

Basically, I am providing a Member (ModelForm) to the template.

What you gave me here should help, I was not familiar with additional
parameters, I will
look more into that.  I just thought I needed the posted data and it
would include the primary key
and then I could load that member again and pass to the save routine.

Thank you!

Are you by any chance using that get_default method as the default for
a model field somewhere else? If so, have you perhaps done it like
this:

myfield = models.ForeignKey(Settore, default=Settore.get_default
())

This would call the get_default() staticmethod when the model is
defined, rather than when a new instance is defined. You need to pass
the callable itself:

myfield = models.ForeignKey(Settore, default=Settore.get_default)

- notice the lack of calling () brackets.

All this said, I agree with Ethan that you should be doing this in a
Manager, although I suspect the error might still occur as long as you
call the method in the default, rather than passing the callable.

Adding button to admin change form

[Aaron]

I need to add a button to the admin change form of certain models,
which would be placed among the save buttons. I've tried overriding
the template submit_line.html, but I am coming under the impression
that this is not possible unless I override the template for my entire
project.

I need this button so that I can write a view or some other kind of
handler that is able to access the model form contained in the admin
change form page. If using the button, I'd override the add_view and
change_view methods of the appropriate ModelAdmin, and do something
special if "_mybutton" is in the POST data. If adding a button to the
change form is not possible, is it possible to add some other link to
the page that would allow me to access the form object?

Re: static models methods

[Ethan Jucovy]

I don't know what the error means, but this looks like the sort of
thing you might want to put on a custom Manager instead -- then you
could say `Settore.objects.get_default()`.

http://docs.djangoproject.com/en/dev/topics/db/managers/#topics-db-managers

(I have a feeling the error wouldn't happen if it was on a manager class.)

Re: Definitive solution for foreignkey filtering in Admin

[Tim Valenta]

Many many thanks for the response.

I had tried that approach, but had no idea what was coming through in
kwargs.  I feel like 'kwargs' on most class objects needs more
thorough documentation for the general users who refer primarily to
the on-site docs.  Even digging through some code, I simply had no
idea.

This should provide a working fix for the sort of filtering I need to
do.  I hope that maybe I or some other person can provide some code to
help simplify this amazingly common dilemma.  Any models that group in
logical relationships of 3 seem to always have this problem, and I'd
love to have a simpler fix to write off in the docs.

ajax problem

[elminio]

Hello,

The situation is that I have a div to which I want to dynamically load
forms for update create etc of my models.

I use generic forms.

And the problem is that when I use javascript with jQuery :
key is already defined:


$("#div_nontetn").load("/model/"+ key + "/update/", {object_id: key},
function(){ });

It doesnt render the site in which is form to fill but automaticaly
submits empty form and redirect to object_detal.

What am I doing wrong ?

Truth values for current database type for custom queries.

[Bill Freeman]

I have a query that is complex enough that, even if it can be done
with filter, exclude, and Qs, I find more maintainable as custom SQL.
That all works fine.

But I want to add the test of a boolean field in my WHERE clause, and
different databases represent true and false differently.
Specifically, during development, and probably for later bug fix
testing, I find it convenient to use sqlite, where true and false are
1 and 0, but we will likely deploy on PostgreSQL, where they (at least
as returned
by the command line tool) be t and f, and the documentation implies
that true and false will also work.

I can clearly check settings from django.conf to see which DB I'm
using, and adjust my queries, but it occurs to me that the ORM already
knows how to represent true and false for the current DB.

Is there a reasonable and unlikely to change way of programatically
asking the ORM for the representations?

Thanks, Bill

image.thumbnail(settings.UPLOADED_IMAGES_SIZE,

image.save(self.photo, 'PNG')
self.photo.name = '%s.png' % os.path.splitext
(self.photo.name)[0]
super(Product, self).save(*args, **kwargs)

everything working but self.photo size(in bytes not width and height)
is wrong(it no changed after resizing), and if we download that image
it have previous size, so i try do it this way:

def save(self, *args, **kwargs):
if self.photo:
image = Image.open(self.photo)
if image.mode not in ('L', 'RGB'):
image = image.convert('RGB')
image.thumbnail(settings.UPLOADED_IMAGES_SIZE,
Image.ANTIALIAS)
tmp_file = StringIO()
image.save(tmp_file, 'PNG')
self.photo.open()
tmp_file.seek(0)
self.photo.write(tmp_file.read())
del image
self.photo.name = '%s.png' % os.path.splitext
(self.photo.name)[0]
# now we have correct image size but i don't know how to
assign it to our image:
# i can't asign it that:
self.photo.size = tmp_file.len
super(Product, self).save(*args, **kwargs)

Anybody know how to solve it?

Re: Troubleshoot import errors

[Hector Garcia]

Check out all your template calls to {% url view_picture %}, you are
probably passing wrong arguments to the reverse URL.

Now that someone has got the "you shouldn't do that" speech out the way,
here's how you can actually achieve it. Install the 'smart if' tag[1]
from djangosnippets, and alter your template code like so:

{% for u in users %}
  {% if u in superu %}
{{ some_content }}
  {% endif %}
{% endfor %}

The smart if tag is allegedly slated for inclusion in django 1.2.

Cheers

I usually create a table using something similar to:

create table temp_member_view as select * from member_view where
rownum < 2;

Where member_view would be the original view name.  I then use the
inspectdb to create the model for the new table and then drop the
table it should create a better model than I do usually when I try to
do it manually.If your view doesn't have an obvious single column
primary key you may want to look at my notes on this subject:

http://projects.django-development.info/trac/dd_dd/wiki/Creating_Django_Views_of_Tables

Great call on overriding save/delete I'll add to my notes and start
doing that as well since I wasn't.

You can't and shouldn't. It's template language, not progamming 
language. It's function to define _how_ to show data.

You need to make that decision in a view which is meant for extracting 
and preparing _what_ to show.

Re: Do reverse relations eventually kill performance?

[Manfre]

Subclass Manager and make this the default manager for all owner
restricted models. Override filter() and get() to check for the
"owner" arg. Raise an error if it is not specified. Also set
use_for_related_fields = True for the manager to cover the reverse
relations.

Redirects on HTTPS

[Tim Sawyer]

I still can't get this to work (original thread at
http://groups.google.com/group/django-users/browse_thread/thread/cdece5ef2e7fd280).
 I'm looking to get a HttpResponseRedirect in my django app to redirect to
HTTPS not HTTP.

I've tried:

* proxy server Apache (the one doing the SSL) does:
SetEnv X-Forwarded-Proto=https
* Apache running django/mod_wsgi does this:
SetEnvIf X-Forwarded-Proto https HTTPS=on

I've also tried:
* Hard coding HttpRequest.is_secure() in django to True

I've tried changing my wsgi file to do this:
_application = django.core.handlers.wsgi.WSGIHandler()

def application(environ, start_response):
environ['HTTPS'] = 'on'
return _application(environ, start_response)


but no luck.

With everything I've tried, it still redirects back to HTTP on a
HttpResponseRedirect.

Any clues anyone?

thanks,

Tim.

Handcrafing. So you need to construct those two views by hand. Also I 
suggest that you override save() method to raise exception if someone 
tries to save something in views accidentally.

Troubleshoot import errors

[Dave]

Hi All, I admit I must totally be missing something. My problem is
that IF I screw up an import somewhere tracking down the problem is a
complete nightmare. The traceback just tells me:

"NoReverseMatch: Reverse for 'view_picture' with arguments '()' and
keyword arguments '{'picture_id': '', 'size': u'small'}' not found"

This is the case no matter which of the 30/40 apps is causing the
problem.

I've tried to use the command line switch to debug imports, however it
just spews out tons of info which so far has proven useless to find
the problem. In most cases when I track down the problem, the
offending import is not even mentioned in the log! I don't understand
why there is not a debug or exception message that simply says where
the problem is.

Any advice help is greatly appreciated. We are just about at our wits
end because tracking down what should be simple issues is consuming
far too much time.

Thanks

Dave

Starting a daemon thread from Django view

[dim]

I am writing a service that should handle HTTP requests according to
following scenario:

- register a job
- make an "ok" response
- do the job
- report the job is complete by making HTTP request to other service

The jobs are often lightweight and will be executed very quickly so I
don't want to use cron-based solutions or queue services - both that
ways are adding too much overhead for such a task.

As far as I know, there is no way (at least no right and easy way) to
use the thread after response was sent. (or maybe I'm wrong here?)
So I'm going to start a new daemon thread to do the job. And my
scenario will look like:

- register a job
- start a new daemon thread for job processing
- make an "ok" response
-- daemon thread will (somewhen) report the job is complete by making
HTTP request to other service

I'm going to do it using a regular threading.Thread with setDaemon
(True)

Is it a reasonable solution?
Are there any hidden dangers in it?
Will it work perfectly with any deployment way? (mod_python, mod_wsgi,
FastCGI)

You haven't shown your models. What is the name of the foreign key
field in Subplace that links to Place? That's the name you should use
in the unicode method.

You haven't posted the code that shows how you instantiate the form.
Clearly your UpdateMember view must be taking more than just the
request parameter - it must include a parameter that gets the object
you want to update in the first place. And when you instantiate the
form for editing, you must be passing the 'instance' parameter, so you
get the data for the form to update. So all you need to do on POST is
to use that parameter again.

def update_member(request, pk):
member = get_object_or_404(member, pk=pk)
if request.POST:
form = MyForm(instance=member, data=request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/wherever/')
else:
form = MyForm(instance=member)

return render_to_response('mytemplate.html', {'form':form})

What do you mean a 'Python file'? If it's in a Python file, you can
use ORM commands. What's the issue?

MultipleForm factory and optional forms

[Norbert Wójtowicz]

I've borrowed Alex Gaynor's code for building MultipleForm factories
[0] and updated it to work with optional form fields.

The idea comes from the following situation: you have a profile page
with many services (eg. blip, twitter, etc) that you link to via
ForeignKey.

class MicroBlog(models.Model):
service = models.IntegerField(choices=SOCIAL_MEDIAS)
nick = models.CharField(max_length=50)
# other stuff (eg. verification, update_date, etc)

You would like to build the profile page quickly - so you use a
ModelForm and the MultipleForm factory.

class MicroBlogForm(forms.ModelForm):
class Meta:
model = MicroBlog

BigProfileForm = multiple_form_factory({
'twitter': SocialMicroBlogForm,
'flaker': SocialMicroBlogForm,
# other kinds of forms (so can't really use querysets.. I
think. I could be wrong!)
}, ['twitter', 'flaker'])

The only problem with this is that all submitted forms should validate
BUT not all forms are required. For example, we can't expect everyone
to have a twitter account. One way is to make the fields optional (but
then we need to validate outside of forms), so the only real way to do
it is to mark optional forms.

I've modified Alex's code to support optional fields:

BigProfileForm = multiple_form_factory({
'twitter': SocialMicroBlogForm,
'flaker': SocialMicroBlogForm,
}, ['twitter', 'flaker']
  , ['twitter']) # twitter is optional, flaker
is required

The modified code is posted below. If possible, I'd appreciate some
comments if this is the right way to go about it. Also, there's one
bug I can't figure out - if an empty form is submitted (without any
data), the rendered form shows required field errors on all forms
(even optional). The correct handling is to only show required field
errors on optional fields that had some data submitted. Could someone
point out where my problem is?

Code:

from django.forms.util import ErrorList
from django.utils.datastructures import SortedDict
from django.utils.safestring import mark_safe

def multiple_form_factory(form_classes, form_order=None,
optional_forms=[]):
   if form_order:
   form_classes = SortedDict([(prefix, form_classes[prefix])
  for prefix in form_order])
   else:
   form_classes = SortedDict(form_classes)
   return type('MultipleForm', (MultipleFormBase,),
   {'form_classes': form_classes,
'optional_forms': optional_forms})

class MultipleFormBase(object):
   def __init__(self, data=None, files=None, auto_id='id_%s',
prefix=None, initial=None, error_class=ErrorList,
label_suffix=':', empty_permitted=False):
   initial = initial or {}
   if prefix is None:
   prefix = ''
   self.forms = []
   self.extra_forms_info = []
   for i, (form_prefix, form_class) in enumerate
(self.form_classes.iteritems()):
   self.extra_forms_info.append({
   'prefix': form_prefix,
   'optional': form_prefix in self.optional_forms,
   })
   self.forms.append(form_class(data, files, auto_id, prefix +
form_prefix,
   initial.get(i, None),
   error_class, label_suffix,
empty_permitted))

   def __unicode__(self):
   return self.as_table()

   def __iter__(self):
   for form in self.forms:
   for field in form:
   yield field

   def non_optional_forms(self):
   for i,form in enumerate(self.forms):
   if self.extra_forms_info[i]['optional'] and not
form._get_changed_data():
   continue
   yield form

   def is_valid(self):
   # raise Exception, list(self.non_optional_forms())
   return all(form.is_valid() for form in self.non_optional_forms
())

   def as_table(self):
   return mark_safe('\n'.join(form.as_table() for form in
self.forms))

   def as_ul(self):
   return mark_safe('\n'.join(form.as_ul() for form in
self.forms))

   def as_p(self):
   return mark_safe('\n'.join(form.as_p() for form in self.forms))

   def is_multipart(self):
   return any(form.is_multipart() for form in self.forms)

   def save(self, commit=True):
   return tuple(form.save(commit) for form in
self.non_optional_forms())
   save.alters_data = True


Thanks in advance,

Re: AttributeError when trying to run syncdb after installing django-friends

Actually it was an error with the app itself and it had been corrected
in a newer version.

You should be using the Django-CMS mailing list for this in the future.

That said, use CMS_PLACEHOLDER_CONF to specify which plugins are
available for which placeholders:

Yes it would work but my case is more complicated and include creating
many related objects from session, with saving them optionally in last
step. That's why I tried to present it as simple as I can. I can sure
make workaround in code to reassign related model after it is saved
but I still wandering why is this needed? It's seems like one step
more needed to take care. I would like to know if it was design
decision or if implementation would be too complicated in some cases.

best,
Bojan

Ok, I realised I'd come across this problem elsewhere in my code and forgot
what I did. The __init__ method should look like;

def __init__(self, *args, **kwargs):
super(MyNewForm, self).__init__(*args, **kwargs)
instance=kwargs.get('instance','')
if instance:
self.initial['start_time'] = 
   datetime.fromtimestamp(delay_instance.start_time)
self.initial['end_time'] = 
   datetime.fromtimestamp(delay_instance.end_time)

Then the floats get changed to datetime objects and render properly.

Open ID & request.user.message_set.create

[cerberos]

request.user.message_set.create(message="Your playlist was added
successfully.")

The docs (http://docs.djangoproject.com/en/dev/topics/auth/#messages)
say
"Finally, note that this messages framework only works with users in
the user database. To send messages to anonymous users, use the
session framework."

Can messages be posted for open id users (are they added to the user
database)?
