Saving info about viewed tags
Hi, I have an Objects Model and a Tags Model with a M2M relationship between them. I want to update info about the tags of the object visited by the user updating it everytime the user requests an Object. Is it a crazy idea? I want to know wich tags are the most viewed by the user and wich are the most recent he has view so that I can recommend him Objects that have also such tags (objects that are related to the ones he is interested in). This is my main idea how the models should be: === class MyObject(models.Model): tags = models.ManyToManyField(Tag) etc. class Tag(models.Model): etc... class RelationModel(models.Model): my_object = models.ForeignKey(MyObject) tag = models.ForeignKey(Tag) times_viewed = models.PositiveIntegerField() latest_view= models.DateTimeField() Problems I see: === - Lets say I have 30 tags for each object, I need to create_or_update 30 rows everytime a user requests an object. That could be a bottleneck :( - The relation table can be very big: 100.000 users x 2.000 tags each user = 200.000.000 rows in the relation table I should limit it to lets say 50 tags per user and in each update overwrite the less viewed and older tags with the new ones. -> more updates on every request :S - Is this the better way to do what I want to do? Any ideas? Thank you for your help. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I'v write some custom tags you can try:
expr http://code.djangoproject.com/wiki/ExprTag
then the sample code is:
{% for question in questions %}
{% expr 'questions/' + question.get_type_display() + '.html' as tmp %}
{% include tmp %}
{% endfor %}
But I don't know if it can do the work, but you can try it.
You should save ExprTag code into some templatetags file, and use load
tag to import it. See the template_python document to get the details.

Try::
{% regroup feature.task_set.all|dictsortreversed:"priority" by
get_priority_display as grouped %}
That is, the "by" argument to {% regroup %} doesn't just have to be a field
name; it can be anything that a variable could resolve.

get_FOO_display and grouped data
Hi,
I have a model with an integer field that uses choices for display
names:
class Task(models.Model):
PRIORITY_CHOICES = (
('0', 'Low'),
('1', 'Normal'),
('2', 'High')
)
priority = models.IntegerField(choices=PRIORITY_CHOICES)
In my view, I'm grouping the data on the priority:
{% regroup feature.task_set.all|dictsortreversed:"priority" by priority
as grouped %}
{% for group in grouped %}
{{ group.grouper }}
However, when I do this, group.grouper expands to "0" or "2", not "Low"
or High". How can I get the display name for this field?
Thanks,
Ross

Searching a ForeignKey
Is there a way to search a CharField contained in a ForeignKey? If one wants to use a foreign key to prevent repetition and duplication of data, wouldn't it only make sense that the foreign key's fields be searchable, as well?

The Django template language does not support arbitrary Python
expressions; only the tags and syntax defined in the template
documentation are allowed. Your best bet here is probably to write a

Dynamic includes in template?
Hi,
Looking at the documentation, I see that you can do "include
template_name" or "include 'template.html'". I'd like to combine these
- concatenating a couple of strings and a variable to make the template
name - but it's not working (no error, but no template included).
This template displays a survey. Each survey question has a 'type'
attribute with several choices defined in the model
("multiplechoice","matrix","ranking" etc).
I'd like to loop through the list of questions and render each question
using the appropriate template, which is determined by the type of
question. So for example a 'multiplechoice' question corresponds to the
'questions/multiplechoice.html' template.
This is the bit that's not working (viewsurvey.html):
{% for question in questions %}
{% include 'questions/' + question.get_type_display() + '.html' %}
{% endfor %}
Why can't I concatenate the strings and variable to include the
relevant template?
The model looks like this:
class Question(models.Model):
Types = ((0,"TrueFalse"),
(1,"MultipleChoice"))
type = models.IntegerField(choices=Types)

graceful shopping cart questions
I downloaded and looked at the django-cart code and noted the views go
cart = request.session.get('cart', None) or Cart()
how can thre session pickle the cart and be accurate if it's stored in
the database or am I confuised? is Django smart enough to know how that
should work and retrive the new information etc?
Feel free to make any comments.
Would it be possible to make a list in the session that stores lists of
items and quantities by reference to the item in the database?

Global Error Handeling and Strange Authentication issues
We have two problems that are similar, but would like handled in two different ways. I have been using django for a few months modifying and adding to an existing app and have a pretty good feel for how most of the framework fits together, but some parts still baffle me, like error handling (even after reading some of the django source) The first thing that I would like to do is something special when an error comes up (all except security errors, i would like to handle those differently, but it may fall along the same lines.) Right now when you are in debug mode, it takes over the entire screen with the wonderful traceback and other debugging info. This is great, except I loose all of my navigation framework. How can I get that wonderful traceback info without losing navigation? I use no frames for the navigation, they are part of the base templates. If I had access to the html of the error page, i would likely strip out the and tags and put it into my own error template that just populates the content block. Part two of this first problems (which I will probably be able to do more easily once i determine the first part) is to when not in debug mode (we could even create our own unique variable to use to determine this), but basically when we are in production mode, we want that entire traceback page, but not in a way a user can understand it. Something simple they can either download and save and send to use, or copy and paste into an e-mail address to us. I might just base64 it would be good enough and then do the reverse on our side to see what their problem was. We might also include some extra debugging information to try and tell what they were doing right before this (we have a bread crumb system already in place we can pull from) to help us debug the problem. Problem two is when clicking on some objects that should not have been shown (We are going to fix the show/not show part that are obvious, but there may be more subtle errors that are harder to catch). Anyway, the clickable link is there, but instead of raising a security traceback, it will do one of two things. 1. Send the user back to the logon page with no reason why they were sent there. They are then confused because typing in their correct username and password will send them right back here because /?next=problem/security/page. Oh, and they are actually still logged in because if you click back, or go to a page they have access to, all is good. 2. A page that just displays something like "you are not allowed to do that" (can't remember the exact wording) This is just about as bad since they have no opportunity to log it, they can use the back button, like they could above, but they also lose the navigation framework. For these errors, I am hoping to have a spot in the base template that can display an errors and basically send the user back to the page where they had the ability to click/post to the problem page and display and error on that page that doing that again will cause a security error with as much info as I can display to help them in that situation. I know about the process_exception middleware method, but it only handles view exceptions, not the selection of URLs or security problems. It looks like security errors are even swallowed by the URL handling code so I don't have any control. I could be misreading the code. Anyone have any ideas how I can solve even one of these problems? Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Hello, I'm having the same problem as this thread: http://groups-beta.google.com/group/django-users/browse_thread/thread/b711b5c4579535c8/ Where to call set_test_cookie? Since a POST to authenticate can come from any page, I need to call set_test_cookie on any page. I'm using the django.contrib.auth.views.login, a pretty basic login setup. Where is the appropriate place for this or is there a better way? I figure I could stick it in one of my context processor functions but want to avoid the hack if possible.

You may want to check out django.newforms which is going to be the replacement for forms and manipulators.

Take a look at: http://www.djangoproject.com/documentation/forms/#custom-forms-and-manipulators Although, the way to create and use custom forms is going to change soon. Just be aware of that. You can create three views, one for each step. In the first view, create a custom manipulator to handle and validate the data that is entered in that first view. If the data is correct, use sessions to store a flag that indicates that the user has entered the information correctly and redirect him to the next view. In the next view you would then check in the session that the flag for the previous view is set. If you will later need the supplied information then store it in the session too, do not use hidden fields to carry it over different views.

Re: Question concerning generic views or date based views in general

Well, the general operation of a generic view is to grab one "list" of
things. Usually this is a list of items in a month, or items in a
year, or items in a day, etc.
However, you can pass extra information to the generic view with the
'extra_context'
Take a look at this: http://awwca.ca/events/
Now, right now, there are no upcoming events, so it only shows all the
past events. However, if there were upcoming events, they would be in
the 'upcoming_events' variable in the context, passed to the template.
You can take a look at the template code here:
http://svn.jayparlar.com/website/trunk/awwca/templates/events/event_list.html
And you can take a look at the urls.py that populates the context for
the template here:
http://svn.jayparlar.com/website/trunk/awwca/events/urls.py
Also, if you want to have stuff in a sidebar, that's always there (no
matter what page you're using), then you'd want something like
template tags. Notice that on every page at awwca.ca, the right
sidebar stuff is always there, and the information there is dynamic.
Look at the "sidebar" div here:
http://svn.jayparlar.com/website/trunk/awwca/templates/base.html, and
notice that it does things like "{%random_thumbnail%}" and "{%
upcoming_events %}" to populate the sidebar.

Yep, the ORM can completely handle that. Check out the urls.py I
pointed out above to see how I select upcoming events from the
database, namely:
def get_upcoming():
return
Event.objects.filter(end_date__gte=datetime.now()).order_by('end_date')
If you don't understand what's going on there, you'll need to read the
documentation more.
Hope this helps,

You just define all needed validators and then in a view you can do this: # get data and errors data = request.POST.copy() errors = manipulator.get_validation_errors(data) manipulator.do_html2python(data) # save data regardless of errors object = manipulator.save(data) # show results to a user if errors: object.complete = False object.save() else: return HttpResponseRedirect(...) > What other problems might I run into by disregarding > manipulator.get_validation_errors and saving anyway? This approach doesn't distinct between absent data (which is ok) and broken data (which is not). I could think of such a hack: you get standard validation errors then set all fields in the manipulator as not required and get validation errors one more time. This way you will get only critical errors: errors = manipulator.get_validation_errors(data) for field in manipulator.fields: field.is_required = False critical_errors = manipulator.get_validation_errors(data) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

No, I think not -- I think that syntax (``queryset.groupby(field).max()``)
actually looks like the best proposal for aggregates I've seen thus far...
I'm taking this to django-dev for more discussion; it'll get seen by more the
right people there.

Hank,
I'm a little confused. Your example uses a ForeignKey to relate Meeting
to MyDay but above you say you'd like a many-to-many relationship. Have
you tried:
class MyDay:
def __init__(self, date):
self.id = date.toordinal()
self.date = date
class Concert(models.Model):
title = models.CharField(maxlength=50)
description = models.CharField(maxlength=50)
date = models.ManyToManyField(MyDay)
class Meeting(models.Model):
title = models.CharField(maxlength=50)
description = models.CharField(maxlength=50)
date = models.ManyToManyField(MyDay)
Which *should* allow this in your templates:
{% for concert in myday.concert_set %}
{{ concert.title}} {{ concert.description }}
{% endfor %}
{% for meeting in myday.meeting_set %}
{{ meeting.title}} {{ meeting.description }}
{% endfor %}
Or maybe I'm misunderstanding what you are trying to do?
BTW, here is more info on M2M's:

Re: Apache ErrorDocument Question.
Thanks Waylan but... It appears that when I configure Apache to limit the request body, if a file is uploaded that exceeds the setting, Apache doesn't seem to pass on anything to mod_python and records an error in error.log.

It seems that mod_python interferes with the mechanism that Apache uses when one configures the ErrorDocument setting. The user gets a message from the browser saying that the connection was dropped.

Me myself, I think that the "group by" functionality isn't a problem;
if you look at how itertools.groupby works, it would be both easy and
natural (ie pythonic) to give querysets a groupby function with
similar semantics and laziness.
The "max", "min" and other such functions might be a little more
problematic, unless groupby returned, rather than a generic iterator,
a special "queryset group" and give _it_ the max/min/etc methods. This
way it would be clear that max() returns a tuple (value, queryset) (to
me, at least...). Also, ...groupby('foo').max() would return the same
result as max(...groupby('foo')), but less efficiently.

Re: High Load
What web server are you using in development ? I suspect this might be a lighttpd / fastcgi problem. Have you tried Apache / mod_python ? Just as a reference I'm managing 90,000+ hits a day on one Apache on a UML virtual server, with the load rarely going above 2. With you setup and Django you should be able to take on the world :-) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

So don't ever create more than one instance of it ;) Regardless of feelings about the Singleton pattern (I'm not a fan), though, this isn't really something that will have a clean solution in Django, if it has a solution at all; because Django model classes map to tables in a relational database, they carry with them the inherent idea of being able to create multiple instances (which would then correspond to multiple rows. You *might* be able to hack something together using one of the various attempts people have made at implementing Singleton in Python [1], but I personally wouldn't recommend it.

Re: Simple CAS 1.0 authentication
Brian, Just a quick note to say *thankyou very much* for making this available. I installed it into one of my development sites over the weekend and it works like a charm. I only tried the middleware version (which is probably more appropriate for an authentication backend) and found it to work just fine. In the end, all I had to do to get CAS authentication operational on my site was to change one line in settings.py and two in urls.py (once I'd installed cas into django.contrib). If that doesn't show the power of middleware then I don't know what does ;) Again, thanks heaps for making this available - it's done the business for me!

Re: Hiding Referrer URL
As this is handled by the browser - you might want to revert to Javascript. I think there is a plugin for JQuery which handles this.

It's a bit non-obvious... The actual data to display is provided by a
method called `flatten_data` that is then used to create a form
like this:
data = manipulator.flatten_data()
form = FormWrapper(manipulator, data, errors)
(This is how generic views work and how custom views should be written).
So you have to provide this method in your manipulator returning a dict
with prefilled values:
def flatten_data(self):
return {
'current': True,
}

Singleton model instance
Hi all, Apologies if this has been asked on the list before, but a search didn't throw up anything relevant. I want to have a series of pages, with certain areas of content which are editable. I don't want to use flatpages, as I'd like the editable content to be broken down into chunks, rather than one big lump of content. Is there a way to easily set a model to have one singleton instance? I've thought about adding some pre-save code to check and only allow for one instance, but wondered if there was a more graceful way to do this? -Phil --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

i18n & server_name
I'm writing multilanguage app, in which i18n happens when client enters certain domain, like in wikipedia. But I got problem - request.META['SERVER_NAME'] always set in ServerName Apache setting, not in queried domain name (which handled in Apache with ServerAlias *.domain.my).
