from the docs 
(http://docs.djangoproject.com/en/1.2/topics/http/sessions/#when-sessions-are-saved):

  # Gotcha: Session is NOT modified, because this alters
  # request.session['foo'] instead of request.session.
  request.session['foo']['bar'] = 'baz'
  In the last case of the above example, we can tell the session
object explicitly that it has been modified by setting the modified
attribute on the session object:

  request.session.modified = True


that's exactly your case.  the session object is saved automatically
only when it's marked as modified.  but when you modify an object
inside the session and not the session itself; it doesn't gets
notified of the change, so you have to tell it explicitly.

What causes request.session to be erased?...When you go to different view?

[Chris Seberino]

Ever time a web page is visited, a view is called and a NEW request
object is passed in right?

Then if I'm not mistaken, it appears you can't maintain
request.session when you visit a new web page and a new view because a
NEW request object is passed in to the new view right?



My personal code visits a certain form multiple times to create new
"posts".  I was trying to collect them in a list I store in the
session as follows

...
elif form.is_valid():
...
request.session["posts"].append(form.cleaned_data)


I noticed that everytime I revisit this form and rerun this view, the
request.session["posts"] lists gets blown away and is empty again!?!?


Am I misunderstanding something about requests and sessions?

Unexpected query behavior

[Skylar Saveland]

If I chain my .filter()s

Collection.objects.filter(collection_revisions__articles=article).filter(collection_revisions__char_fi="p")

collection_revisions is related_name, FK to Collection.
articles relname, m2m with collection_revision (with a through table).

I get ~20 results with this query::


SELECT "catalog_collection"."id",
...

   "catalog_collection"."collection_type_id"
FROM "catalog_collection"
INNER JOIN "catalog_collection_revision" ON ("catalog_collection"."id"
= "catalog_collection_revision"."collection_id")
INNER JOIN "catalog_collection_revision_item" ON
("catalog_collection_revision"."id" =
"catalog_collection_revision_item"."collection_revision_id")
INNER JOIN "catalog_collection_revision" T5 ON
("catalog_collection"."id" = T5."collection_id")
WHERE ("catalog_collection"."is_archived" = False
   AND "catalog_collection_revision_item"."article_id" = 3
   AND T5."revision_tag" = p)



When I put the two queries within the same call to filter, I thought
it would be the same.  But, there is not the 3rd INNER JOIN and it
only returns 1 object::

Collection.objects.filter(collection_revisions__articles=article,
filter(collection_revisions__revision_tag="p")

SELECT "catalog_collection"."id",
...

   "catalog_collection"."collection_type_id"
FROM "catalog_collection"
INNER JOIN "catalog_collection_revision" ON ("catalog_collection"."id"
= "catalog_collection_revision"."collection_id")
INNER JOIN "catalog_collection_revision_item" ON
("catalog_collection_revision"."id" =
"catalog_collection_revision_item"."collection_revision_id")
WHERE ("catalog_collection"."is_archived" = False
   AND "catalog_collection_revision_item"."article_id" = 3
   AND "catalog_collection_revision"."revision_tag" = p)


Is this the expected behavior?  Can someone explain what's going on?

how to dynamically update model fields?

[zweb]

I want to provide a method as follows,

def update_some_model_field(key, field_name, value):
  '''user provides the primary key of row, field name in model and the
value and the method updates the field for that row with the value'''

1.  model_obj = Some_model.objects.get(pk = key)
2.  model_obj."field_name" = value  ## HOW to make this line generic??
I do not want to do lots of If as shown below.
3. model_obj.save()


For line 2 another way to write it is  as follows, which I want to
avoid:

if field_name == "field_a":
model_obj.field_a = value
elif field_name == "field_b":
   model_obj.field_b = value
and so on... for 20 fields of 20 models

Any suggestions?

Deleting sessions without Request object

[Greg Pelly]

Is it possible to log out a user manually?  The desired result is that after
I do this, the user will be forced to log in again.  I will not have an
active Request object (ie, this will be done from the admin app or a
management command, not a view).

Can I simply add the Session table to the admin app and manually delete a
user's entry?

Thanks,
Greg

How to modify many to many data without auto saving to DB?

[zweb]

Assume there is many to many between publication and article. (example
from django docs)

By default following stmt will auto save the relationship between
a_publication and article11 in database.

a_publication.articles = [article11]

how do I get that so that it changes only in memory (for session) but
does not get saved in DB unless explicitly told to save?

you need a password for registering which will work on all freenode channels. 
Get onto freenode and do:
/msg nickserv register  

this will register your nick if it is not already registered. Once registered,

/msg nickserv identify

I fixed some things, I'm a bit ambivalent about 79 char limit. I feel
that with monitors getting larger, I think a lot of people use wider
windows, even if you have two 100-char windows side by side, you'll
still have some space left on many monitors. And there's a lot less
wrapping going from 79 to 99.

I also think code like:

if: ..
else: ..

..

looks more readable in most cases (depending on how long the clauses
are), than:

if:
..
else:
..
..

In other words, I always try to add a line after this type of
construct. (I know I missed it in a few places in current tutorial.)

That's something I haven't done before so I'm not sure how to do it.

Hmm, all views work fine for me when logged out..

I'm running into problems with this tag in some cases. For example, in
admin's template, if I say {% url dbe.blog %} or just {% blog %}, or
add '.urls' to either, it's unable to reverse and throws an error. The
same thing happens when I try to do {% blog.urls post.id %} for the
"comments" link that goes on front page. I haven't used reverse before
so I might be missing something here.. In all other links in this
tutorial, reverse works fine.

Actually comment form is called cf, and on save it returns comment

fix..

I don't see how this function can be simplified with calendar. I'm

Re: Get pk before commit

[Andy McKay]

I wouldn't actually recommend saving your file with the filename being the 
primary key of your model anyway. It makes it a pain if you do database dumps 
or loads and need to keep the primary key in sync with your files. I would 
recommend making a UID field on your model (which also doesn't require a 
transaction) and using that for your filename.

manager not getting used by User subclass when new User subclass is created in admin interface

[Jacob Fenwick]

I want to change the behavior of what happens when you add User
objects in the admin.

I subclassed the User object and added a custom manager that changes
the behavior of create_user.

Then I created a ModelAdmin corresponding to this subclassed User and
registered them together with the admin.

The trouble is, when I create a user, nothing different happens.

The message "In MyUserManager" should be printed out, but it's not.

I've posted the code below.

Does anyone see any mistakes? Or is there any hooks I'm missing or
holes in my logic?


Thanks,

Jacob

You can get the full list of objects in the view with
MyModel.objects.all(). Send that to the template context and then
iterate through with {% for item in myobjects %}.

The question doesn't really make sense. Django isn't a table-based
relational db manager, like Access is. It's a tool for creating full-
featured web applications. As such a page can do whatever you want to
program it to do: display as many tables as you want, update them,
whatever. But you need to write the code to do that. There isn't any
documentation about that particular thing, because that's only one use
case out of an infinite number of possible uses.

Yes, i've tried it with the existing django.po file. And my other try

makemessages  removes my manualy added entries from django.po

Re: list display based on logged-in user

[raj]

You are trying to override change_view instead of changelist_view.
Otherwise your approach must work.
class CustomAdmin(admin.ModelAdmin):
def changelist_view(whatever_args_are_here):
if condition:
self.list_display = custom_list
   return super(CustomAdmin, self).changelist_view(...)

are you trying to do the request from Django? to the same server? on
the development server?

the development server is single-request.  it won't answer to a new
request until the current one has been completed.  if you need to do a
request to yourself, use a real server.

of course, if you're requesting to yourself, you shouldn't have to go
through HTTP, it would far better to directly access the underlying
resources.

HATEOAS: http://blogs.sun.com/craigmcc/entry/why_hateoas

in short, the server shouldn't bother with policy.  you should strive
to create your resources so that everything that's allowable is
acceptable.

in your example: when you POST a new 'payment', you have to refer to
the 'booking' and 'room' resources involved.  these references should
be URLs in the POST data.  remember that REST is not CRUD, you have to
do fairly extensive validations and sanitizations on POSTed data
before accepting it.  so, the 'payment' resource should verify that
the 'booking' and 'room' URLs referenced by the client actually exist
and are in the correct state (i.e. the room isn't paid yet).

if anything is wrong with the data, don't write anything and respond
with a client error, like 400, 406, 409, 412 or similar (check
http://en.wikipedia.org/wiki/List_of_HTTP_status_codes). only answer
with a 200 (or better, with a 302 to the new resource) if everything
was correctly verified and created.

that way, you don't care if the client has just GET the related
resources, or if that was a week ago, or if the user copied from a
napkin. if the reference is valid, accept it; if it's not, don't.

urllib and writing web service clients

[irum]

Hi,
I am relatively new to working with django and web services. I am
using django-piston and I posted this on that group as well but got no
reply yet. Posting it here since its more active community and my
problem is not related to Django-piston in particular but rather
Django and web services in general. Hoping to get a reply from here:)

I am trying to implement a small
example of a RESTful web service i.e a hotel booking service. I have
implemented my resources successfully with read, update and delete
methods according to my specifications. I can invoke them successfully
using 'curl' and get the desired status codes. The problem now I am
stuck in implementing full behavior of my service that invokes a
particular resource after performing a certain method on a resource.
For example, after invoking successfully a POST method on 'booking'
resource, I want to invoke a POST on 'payment' resource.

My main problem is :
- where do I implement all the specifications for my RESTful web
service that invokes methods on these resources in a specific sequence
as desired. Is it in the 'view.py' file that I create in the 'api'
folder? Can someone give me any example on how to write web service
clients in django / django-piston? I googled but found no good result.

- Secondly, my main problem is how do I invoke these methods with in
my code? I have tried urllib/ urllib2. When I invoke a remote address
like 'http://www.example.com', it returns the html file but when I
invoke local host, i.e. http://127.0.0.1:8000/api/hb/bookings/21/ ,
curl does not respond when I invoke that handler from curl on command
prompt. My code is like this:

class RoomHandler(BaseHandler):
   allowed_methods = ('GET', 'PUT', 'POST', 'DELETE')
   model = room
   fields = ('rType', 'floor')

   def read(self, request, id=0):
.
 if b:
  b = booking.objects.get(id=id)
  response = room.objects.filter(id = b.room_id)
  req = urllib2.Request('http://127.0.0.1:8000/api/hb/
bookings/21/')
  #req = urllib2.Request('http://www.example.com')
  response = urllib2.urlopen(req)
  the_page = response.read()
  type(the_page)
  return the_page

>From command prompt, I invoke. curl 
>http://127.0.0.1:8000/api/hb/bookings/21/rooms/
It does not respond anything, even if left for long time. However if I
use remote url, i.e. :
req = urllib2.Request('http://www.example.com') , it returns the html
file. Where am I going wrong?

Thirdly, how do I implement conditions in my client to invoke a
certain method of a resource, i.e. before invoking POST on a 'payment'
resource, I want to perform a GET on 'booking' and 'room' resource,
only if I get response code of 200 (i.e. booking and room resource is
created), I should be able to invoke POST on 'payment' resource else
it should set a flag to false.  I will be implementing an algorithm,
but I was thinking can we put conditions on invoking methods of
resource like we would do with JML for java interfaces?

I have been stuck with these problems for almost two weeks, googling
and trying different things but I am still stuck. Hoping to hear
something from here.

Thankyou for your time and looking forward,
Irum

Failed unit test when using client.get()

[tiemonster]

I'm attempting to run a test suite. I am able to log in successfully,

split views & shared tables for apps

[alan-l]

Hi,

Im looking to use django to merge 2 MS Access databases into one and
was wondering the following:

Can a front end view support displaying 2 tables in one view? so
having a contact on the top half and the company details on the bottom
half?
Also, can the view support read,update & delete all within the one
page? I wouldn't expect it to update both tables at the same time,
although if the forigen key for the company changed in the contact
table within this view, i would like to see the company table half of
the view refresh to the changed company.

If anyone would be so kind to show me the particular django
documentation page that explores the above or if i could have a very
basic example, it would be most appreciated.


Kind regards,

Alan

More complex or more detailed?  (I would argue that The Django Book is
about as high quality as you are ever going to get for a free
tutorial)

Try: http://www.hoboes.com/NetLife/pytown/django-beyond-sql/

or: http://opensourcebridge.org/2009/wiki/Django%3A_Thinking_Outside_The_Blog

or: http://www.slideshare.net/jacobian/django-in-the-real-world-175

The real issue is that, because Django is a framework, designed to
meet N number of possible needs, once you get "beyond the basics", the
specifics start to diverge more and more from what _you_ actually need
to do.

Django return redirect() with parameters

[jacob-pl]

In my view function I want to call another view and pass data to it :

return redirect('some-view-name', backend, form.cleaned_data)
, where backend is of registration.backends object, and
form.cleaned_data is a dict of form data (but both must be either sent
as *args or **kwargs to prevent raising Don't mix *args and **kwargs
in call to reverse()! error). From what I've found in the docs :

def my_view(request):
...
return redirect('some-view-name', foo='bar')

It looks like I need to provide 'some-view-name' argument, but is it
just the name of the view function, or the name of the url ? So I
would like to make it similar to the way it's done in django-
registration, where :

to, args, kwargs = backend.post_registration_redirect(request,
new_user)
return redirect(to, *args, **kwargs)

def post_registration_redirect(self, request, user):
return ('registration_complete', (), {})

Ok so now, can I call directly my view function or do I need to
provide a url for it ? And what more important, how my function
declaration (and a url if needed) should look like ? Both backend, and
cleaned_data are just passed through this view for a later usage. I've
tried this, but it's improper :

url(r'^link/$', some-view-name)
def some-view-name(request, *args):
As well as this :

return redirect('some_url', backend=backend, dataform.cleaned_data)
url(r'^link/$', some-view-name)
def some-view-name(request, backend, data):

still NoReverseMatch . But in django-registration, I've seen something
like this :

url(r'^register/$',register,{'backend':
'registration.backends.default.DefaultBackend'},
name='registration_register'),

def register(request, backend, success_url=None, form_class=None,
 disallowed_url='registration_disallowed',
 template_name='user/login_logout_register/
registration_form.html',
 extra_context=None):

Re: db_schema support was broken by Debian upgrade: 'class Meta' got invalid attribute(s): db_schema

[MiddleForkGIS]

Thank you, I'm sure you're essentially correct, with one wrinkle.
What I believe happened was that the Debian upgrade resulted in a
change from python 2.5 to 2.6,
and so I believe that what happened was that resulted in the
pythonpath changing as well, and pointing
to the Debian 'python-django' package rather than my local copy, which
as you noted contained the patch.

Good advice of course about using volatile and testing packages in a
production environment
as this of course proves.

For what it's worth, I have (er - had) been using the ticket 6148
patch since January and found it
to work without incident in pulling and delivering data from multiple
schemas.

Thanks again,
-
Steve

Re: Accessing context in templatetags

[Miha V]

Venkatraman,

there was something I was missing, and just found the solution. The
tag is defined as  (overly simplified)

@register.filter
@stringfilter
def cmstags(value, arg=None):
return '%s' % value

the value is the HTML content. And I needed another context-related
parameter in the filter as well.

And actually, I just found a way to pass an argument that I need to
filter.

So, where we're rendering,

{{ document.content|default_if_none:""|cmstags:document.id|textile|
safe }}

I just add ":document.id" to pass an argument in, and that's it. I
could also pass the whole context, but the ID is what I needed,
really.

Thanks!

Re: Accessing context in templatetags

[Venkatraman S]

If you are using  render_to_response to load a page and are using template
tags in that page then pass the context (this in views.py for that app)

For eg:
def do_something(request):
 ...
 ...
 return render_to_response('multimedia.html', {'videos': videos} ,
context_instance = RequestContext(request)  )

And in the template tag use something similar to:
@register.inclusion_tag('news.html', takes_context = True)
def show_news_sidebar(context):
  request = context['request']
  news = getNewsrequest)
  return {'news': news}

Was that your problem or did i just misunderstood you?

Accessing context in templatetags

[Miha V]

Hi!

Is there a way to access context from within templatetags?
Specifically, we only load the templatetags and do the processing when
the filters get registered, so we're not using the actual filters or
tags {% someting %} in the templates.

What we do is we replace some of the markup () with
another markup (), but we'd like to have access to
the template's context as well (because this id is "local" to
document, which is passed to template via context).

>From what I've found, there is no way to pass arguments to load ({%
load cms_tags context %}) and context is not available otherwise.

Any ideas? Is there perhaps a better to tackle this challenge?

Kind regards,
  Miha.

Hello,

I am programming a small CMS on Django, I have editable pages, now I

1.) Where is the right place to place news loader?  
TEMPLATE_CONTEXT_PROCESSORS seems to be a good place and easy to  
implement. Another possibility is a middleware, I feel, that it should  
go there instead of TEMPLATE_CONTEXT_PROCESSORS.


2.) If I use middleware, how do I smuggle variables into templates? It

I used template context processors to solve this problem, it is easier to

But can somebody answer my second question please? I need to know how can  
I transfer variables from middleware into templates.

Re: News on every page

That depends entirely on your cache configuration!
Caching in django: http://docs.djangoproject.com/en/dev/topics/cache/

Automatic caching modules that rely on memcached exist, like Johnny
Cache (http://packages.python.org/johnny-cache/) and Django Cache
Machine (http://github.com/jbalogh/django-cache-machine)

Thanks, but the code you give can't generate the error "QuerySet'
object has no attribute 'reel_set'", as om is not a QuerySet object.
Please also post the actual error and traceback.

Re: How to commit ManyToManyField with ModelForm

[Sævar Öfjörð]

Have you tried resetting your database and syncing it again?
If there are columns missing it sounds like you added them after you
did a manage.py syncdb
Django will not alter your tables after they have been created. More
info on this here:
http://docs.djangoproject.com/en/dev/ref/django-admin/?from=olddocs#syncdb

So I would try:

python manage.py reset appname
python manage.py syncdb

Just keep in mind that you'll lose your previously stored data.

Although you haven't posted your models, or the actual code causing
the problem, the reference to a QuerySet gives a hint as to the
problem.

Foreign key relationships are of course attributes of individual model
instances, not querysets. So this won't work:

MyObject.objects.filter(whatever=whatever).reel_set.all()# NO

because filter returns a queryset, not an instance. You could do:

MyObject.objects.get(whatever=whatever).reel_set.all()

because get returns a single instance, assuming there is only one that
matches the query parameters (otherwise you will get a
MultipleObjectsReturned exception). Or, you could do:

   MyObject.objects.filter(whatever=whatever)[0].reel_set.all()

where you get an individual object from the qs before accessing its
reel_set relation (although if there are no matches, you will get an
IndexError).

reverse relationships and their creation

[Alex]

Hi,
I am getting a 'QuerySet' object has no attribute 'reel_set' on a
reverse relationship query.

I am pretty sure the models are correct which has made me look at what
else might be the problem. So far I have thought of:

- no relationships instances have been created between the two models
so effectively the set is empty which is a problem - is it?  (this
seems like an unlikely cause)

- the 'Reel' model was created *after* instances of its foreign key
had been created - so I am wondering if syncdb doesn't create the _set
field - this also seems an unlikely cause of the problem as adding
foreign keys to models with existing instances is likely to happen a
lot during development

- something to do with INSTALLED_APPS ? I have changed the order to
ensure that the foreign key model (Reel)  appears before the model it
has a foreign key to.

- other ideas?

Thanks for any thoughts,

Alex

That's not factual, django has built in support for python, and there
are a multitude of python RPC libraries, some of which are included in
python.

Examples include:

SUDS/soaplib for SOAP RPC
xmlrpclib for XML-RPC
rpyc for python specific RPC server/client
celery/RabbitMQ for AMQP style message bus
py-lasso for SAML RPC

etc etc ad infinitum

 I tried to subclass the User class and set the is_active default to true
 but apparently you can't override fields in a parent model:

 http://docs.djangoproject.com/en/1.2/topics/db/models/#field-name-hiding-is-not-permitted

 Is there some sort of ModelAdmin magic that could solve this problem?

 Or is there some other method that can be arrived at through subclassing
 the User object?

Are you manually adding the field to your po file?

Are you running "django-admin.py compilemessages" to create the
relevant django.mo file after the event?

Are there other strings in the same template that _are_ being translated?

Which version of django are you using?

Which language are you translating too?

save_image_file

[yelbuke]

Hi all,

I'm building a image-upload based site. And having some problems
resizing, renaming, saving. At last i've found save_image_file()
method. But i couldnt found a documentation about this method. I think
i need some help about that point.

Thanks to all,
