mobile cookie related issue, is it a bug in django?
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi,
I found that request.user is not set on all requests when accessing my
under development website from mobile.
I have put the following in one of my middlewares for debugging:
class MyMiddleware(object):
def process_request(self, request):
...
print request.META.get(
"REMOTE_ADDR", "NO IP"
), request.vuser, request.path, request.META.get(
"HTTP_COOKIE"
), request.COOKIES
[request.vuser is derived from request.user, if its None, it means
request.user was AnonymousUser]

extending user model, a different approach
Hi,
I realized a new way to extend user models, it is simpler than official
get_profile approach of django[1] as there is only one model to work with,
and relationships are kept on the right model, and gives a less hacky feel
than "replaces_module" method[2].
User.add_to_class("openid", models.URLField(blank=True))
User._meta.admin.fields += (
("AmitCom Extensions", { 'fields': ('openid', ) }),
)
*class* UserExtension(object):
*def* _get_comments(self):
*return* Comment.objects.get(user=self, is_public=True)
public_comments = property(_get_comments)
*del* _get_comments
User.__bases__ = User.__bases__ + ( UserExtension, )
Read my blog post about the same[3] for a longer discussion about pros and
cons. How does it sound?

This will reverse the order of objects, you do not want to show the oldest
post on the main page of your blog. What I am suggesting only changes the
page numbering.

reverse pagination
Hi, You are all aware of object pagination, search results, your photo on flickr, stories on reddit, all have a next page/previous page paradigm. Django makes it trivially easy to create such pages by providing object_list generic view. There are some problems with the current implementation of pagination that we see around, page no 0/1 is assigned to the latest objects in the list. While in search result this makes little difference, in other cases it has a few consequences. In reddit for example, you are on the main page, you see 25 stories there, you take 10 minutes to go through all of them, and click next. There is a good chance that 3-5 stories on the first page would have moved to now second page, and you will see them again. Not a good experience, but acceptable. You spend next 3-4 hours working, and click back to see the stories on the first page, you are taken to page 0, and there are good chances you have missed 12 stories that moved from first page to second, as your current page labelled second page became third. This is all quite confusing if you think about it. [I am assuming from this discussion the stories changing their relative rankings for simplicity, you can take example of flickr group photos, they also change rapidly, and order does not change there]. Another problem is, I am page 26 of this flickr group, and I see some fellow has posted 8 nice photos to the group. I bookmark the page, and come back later/email it to a friend, and by the time the page is visited again, 100s of new photos has been added and the content of page 26 is now on page 29 or so. The last consequence of this is caching difficulty. If a group has 5 thousand pages worth 30 photos each, and one more photo gets added, either the page number of the photos in each page will change for 5 thousand of those pages. This will happen on each photo being added, and there for the page can hardly be ever cached. I propose a solution to this problem, I call it reverse pagination, and this blog is currently using a patched django to demonstrate it. In reverse pagination, page no 0/1 is assigned to the older page ever. When on reddit home page, and click next, you will not go to page 2, you will jump to page 20566 or something like that. The content of page 20566 will never change, only the content of latest page would be changing while new items are being added. This means all pages other than the main page can be cached for the rest of the life span of the website. And user will not face the other two problems I listed above. Only downside is on the main page/latest page, you will upto 19 items if you paginate by 10 items per page. Here is the patch for django. http://code.djangoproject.com/ticket/4956 http://www.amitu.com/blog/2007/july/reverse-pagination/ Feedbacks appreciated! -- Amit Upadhyay http://www.amitu.com/blog/ +91-9820-295-512 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

One of the ideas in my mind to extend this proof of concept was "named
bundles". I was looking at them because of CSS issues, but same can be
applied to both.
I like the simplicity here, that you do not have to define bundles and use
them in two separate steps, but what google does, making creation of bundle
a conscious extra step, a little bit of hassle but more flexible for such
requirements. Lets say we write a command line script "create_bundle" [lets
say, part of manager.py if it gets to django proper], that will take a
bundle name, and a set of images as input and create the bundle. Then in
template files we can refer to the bundle names in {% img %} tag.
create_bundle script will have to store the metadata about the names of
images that have gone in the bundle and their relative order in some other
place. These are additional complexities to tackle, nothing really
difficult, a little inconvenient.
We can probably go with both kind of bundles, if {% img %} supplies a bundle
name, use named bundle, otherwise do what is being done current.
Anyway, it's an interesting idea and nice to see an implementation.

I am not sure I understood your concern here. There are many things wrong,
its just a prototype, I am assuming the images are /static/something.ext and
are all saved in the MEDIA_DIRECTORY. Suggestions welcome. [I was thinking
what if the images are served from a different host, S3?, all those cases
will cause problems and will have to be thought before it can go beyond
prototype stage to candidate for contrib].

Server side resizing was compulsory as otherwise the background technique
would not work. AFAIK. Browser will just show the part of image, and does
not shrink the background to fit.

Re: Module imports in models
Hi Clint,This is due to magic that django performs on models. The class you defined lands up in some other module that django created, and module level imports are not passed along. You can solve your problem either by importing within the _pre_save, or define your Meta class as: class Meta: module_constants = globals()On 3/15/06, Clint Ecker <[EMAIL PROTECTED]> wrote: I'm using Django 0.91-svn if that matters On 3/14/06, Clint Ecker < [EMAIL PROTECTED]> wrote: I'm having an odd problem when trying to import some python modules in my Django models.

So, no matter what I "SetEnv", it doesn't run through mod_python to myscripts. Apart from the SetEnv issue, I've imported most of the djangomodules into the above code as recommended by Adrian in the docs, and
they all imported successfully, or at least until something triggersthe django handler to take over and it complains about theDJANGO_SETTINGS_MODULE not being set.The catch here is, I did this after I had problems with my actual
project not working. My original project shows the django 404 wheneverI request a page that isn't configured in urls.py, but whenever Iaccess a view that does exist I get the all too popular "Segfault
(11)" and mod_python reloads the django handler.I've tried everything I can think of, and every suggestion that hasbeen made on the list to date, but to no avail. Can anyone suggestsome additional steps that I can take to produce valuable information?
How will I get the SetEnv directives working correctly?I'm off to bed now, I'll check my mail as soon as I hit the desk again...Thanks in advance--Kenneth Kalmer

I`ve got couple of questions about auth system. Just a directions..1. How do I extend base User class? I`ve read about subclassing, but it
was two month ago and it was not very clear.. Is there any new method?I think you are talking about http://code.djangoproject.com/wiki/ExtendedUserModel
. I have not tried it, and do not know the actual benefit, but if you follow the following steps you may not have to worry about it. Some one please correct me if I am wrong.
2. I want to have login form on each page. How should I process form,if I want to stay inside built-in auth system? Dunno what should myView be.One option is to use the django login page for form processing, but if you do that you will miss the django's super cool error reporting in the same form feature. Also may be you want to have a remember me kind of check box in the login page. This is what I recommend:
from django.parts.auth.formfields import AuthenticationFormclass LoginManipulator(AuthenticationForm): def __init__(self, request): AuthenticationForm.__init__(self, request)
self.fields.append( formfields.CheckboxField(field_name="remember") )def index(request): manipulator = LoginManipulator(request) redirect_to = request.REQUEST.get
('next','') if request.POST: # If data was POSTed, we're trying to create a new Place. new_data = request.POST.copy() # Check for errors. errors = manipulator.get_validation_errors
(new_data) if not errors: # No errors. This means we can save the data! request.session[users.SESSION_KEY] = manipulator.get_user_id() request.session.delete_test_cookie
() if request.REQUEST.has_key('next'): return HttpResponseRedirect(request.REQUEST['next']) else: return HttpResponseRedirect("../home/") else: request.session.set_test_cookie
() errors = new_data = {} # Create the FormWrapper, template, context, response. form = formfields.FormWrapper(manipulator, new_data, errors) return render_to_response('myapp/index',
{'form': form, 'signin_page': True, 'redirect_to': redirect_to}, context_instance=DjangoContext(request))Note: You can see I have just ignored the remember me checkbox for now, here you can set permanent cookie etc, which I havent done so far.
Relevant snippet from my template:{% if user.is_anonymous %} {% if redirect_to %} action="" redirect_to }}">
{% else %} action=""> {% endif %} Sign in{% if form.has_errors
%}Email or password incorrect{% endif %}
{{
form.username }} {{ form.password }}
{{ form.remember }}
And the logout view is:def logout(request): del request.session[users.SESSION_KEY] return HttpResponseRedirect("../")
Finally change the file django_src/django/views/auth/login.py and edit the following line:LOGIN_URL = '/accounts/login/'to make it read:LOGIN_URL = '/my_login_page/'
where my_login_page is the page where you want you login page to be, if your login form is in all the pages, you may still have a page devoted to login, explaining why one should login to your system. HTH,

On 1/17/06, tonemcd <[EMAIL PROTECTED]> wrote: Seriously, this is a major thing for any kind of migration we have inmind from Zope -> Django, so any thoughts on how to do this would begreatly appreciated.Hi,In my personal experience, django authentication framework is very thin, and you can bypass it completely without much penalty and use one of your own. What you get by django anuthentication is @login_required, request.user and user auto variable in DjangoContext Context for templates. The internals or request.user magic is pretty trivial, request.session[users.SESSION_KEY] is queried to get the user_id, and request.user is initialized with corresponding user. If you are ready to write a @ldap_login_required decorator which make sure request.session[users.SESSION_KEY] is a valid ldap user id, or redirects to you custom login pagewrite a check_password_and_get_id_else_exception(username, password) to be used by login handling view, which sets the returned id to request.session[users.SESSION_KEY] use get_ldap_user(request) instead of request.user, andmanually set the the user variable in the django context, you are done, that is almost all you need. Please don't let lack of features in defauld django authentication framework deter you from using the rest of it. We need better documentation to instill confidence in developers for the same, but what django provides is very simiplistic and you can write your custom authentication etc very easily.

Re: Managing static media urls
On 1/14/06, Greg <[EMAIL PROTECTED]> wrote: your folder structure. This issue seems especially pertinent for Djangobecause although the mechanism for assembling several apps together onone server is a sweet way to make it easy to combine and reconfigure applications, having to specify a single global MEDIA_ROOT/MEDIA_URLkind of limits it. You can't just put static files in the samedirectory as the template files, like JSP developers (for instance)often do. It'd be convenient if each app had "media" subdirectory or something to go with its models, views, and templates. And actually,the admin app is an excellent example of this! But admin has to haveits own special setting (ADMIN_MEDIA_PREFIX) and handler to make itwork. Is there any suggested strategy for how other apps can have their own media directories too? What's the common practice? Static files are best served by basic http servers and not django. Django tries to support serving static files, but that is only for convenience in development. Just now I finished deploying a django project under mod_pythong/apache, and my approach was to setup a /static url pointing to a directory containing static files and I setup django's static file serving view for that, I did that till the development lasted, and then I moved it to apache, and put a: SetHandler Nonelike directive in apache conf to bypass django for them. I have setup apache to server / using django. /static contained directores for different application, modified ADMIN_MEDIA_PREFIX to point to this location, and developed my other application assuming my static files will be available at /static/myapp/. The only thing I am missing in this approach is: my 404 views are not called when some file is unavailable, and ugly looking apache default comes up. I can change apache's 404 page to someother, but it seems it has to be static html file, not explored it much, but then its not really too bad. -- Amit UpadhyayBlog: http://www.rootshell.be/~upadhyay+91-9867-359-701
