Re: SQL VIEWs as Django Models for aggregation --- delete() issues with django.db.models.query: delete_objects

For the record, I'm still keen to get aggregates supported in Django.
After a few distractions along the way (the unicode and oracle branch
merges), I believe Malcolm is currently working on the Query rewrite
that is the prerequisite for aggregates. Hopefully I will get a chance
to get some aggregates happening in the near future (but I've said
that before... :-)

When I need aggregates at the moment, I'm generally falling back into
raw SQL, or occasionally using the extra() clause on a queryset. Using
the 'extra' clause can get you where you want (annotated rows in a
database) by adding items to the select clause, which will appear as
extra attributes on objects from the query set.

The difficulty comes in getting GROUP BY and HAVING clauses into your
query. This is because Django doesn't currently have support for these
clauses inside Q objects. You can cheat a little by exploiting the
fact that WHERE clauses are the last in the chain, but it's not
particularly robust approach to the problem.

This is certainly a novel approach.

On the general topic - adding Django support for DB-level views is
something I have had banging around in my brain for a while. Its an
obvious blind spot in the existing functionality of Django, and it
should be a relatively clean extension of the existing Model/metamodel
framework.

However, I haven't looked at the problem in detail, and probably won't
have time to for a while. If someone else were to have a go at
implementing support for Views, I'm sure it would be looked upon
favorably.

I'm not sure I'm wild about this as a solution to the problem.
Deleting via a queryset is a 'bulk delete' operation, which is handled
quite separately from a normal delete. Django deliberately doesn't
call delete on individual objects in this case. If you are deleting a
lot of objects, calling delete on each object to be deleted can easily
be a very expensive operation, especially when you look at the
signalling and processing overhead.

You can get the list of model fields from:

some_model_instance._meta.fields

and

some_model_instance._meta.many_to_many

This gives you the Field instance, which can tell you the field name,
the data type, and provides handles for some datatype conversion
(e.g., string to Python type, via to_python).

Looks like your data file contains a value of "0.1", but the field
says it should be an integer. 0.1 isn't an integer, so Django throws
an error.

This is not a discussion of how to fix/improve Django itself, so
django-users is the right forum.

Test response context & template always as lists?

[oggie rob]

Hi all,
Playing around with the test client I found it frustrating that
"context" can either be a single context or a list, depending on how
the template is rendered. My feeling is they should always return
lists. Likewise for the "template" field. I can see that no matter
what there is a chance of the test breaking unexpectedly but I think
it would happen less & coding would be simpler if those always
returned lists.

Should I write up a patch for this or is there a benefit to the
current approach that I can't see?

newforms-admin: admin related field options

I am using the newforms-admin branch, which is really great.  But I

Re: URL design for security?

Thanks for the replies.  No, I haven't incorporated authentication
yet.  I guess I was
thinking that even if the user was logged in, the URL still would be
showing potentially
sensitive info.  I was thinking maybe I needed to create some random
sequence of
letters/numbers, store that in a model field and use it as the pk
which would then
up in the URL params.  Probably overkill with my limited experience.
I'll take a look
at the authentication module and try some tests.  Thanks again.

I did a quick search around, I think this is what you're looking for:

Re: is there any host servers that supports Django based sites?

[Nathan Ostgard]

It's a question of value to the customer. Of course they don't
necessarily care about Django -- they care about the product. It's up
to you to illustrate to them, using Django, that you can deliver a
better product to them than the competition, and that the costs are
worth it. I've found that the easiest way to do this with Django is
through the rapid development process and the admin interface.

If you don't want to deal with making them sign up for a new host, you
could always sign up for the host yourself and pass the costs on to
the customer.

If you're using an SVN copy (not 0.96), there is already a context
processor for this. Add 'django.core.context_processors.media' to
TEMPLATE_CONTEXT_PROCESSORS in settings.py and you will be able to use
{{ MEDIA_URL }} in your templates.

Re: About create a database table dynamicly

[Ned Batchelder]

Generally, creating a table dynamically is the wrong thing to do.  How 
will these tables differ from each other?  For example, what user 
information is used to create the table?  If each of the tables has the 
same structure, then you should create one table with an extra column to 
distinguish the different "tables". 

And what code will read and write the records in the table?  Don't you 
need Django model classes to go with the new table?

Hello Joe,
The email module of the python standard library allows to parse e-mail
messages very easily.
Currently I'm working in the spare time on a django-based webmail
IMAP4 client using imaplib. The code is not very clean but you could
have a look at http://code.google.com/p/django-mail/ to see how I'm
doing email message parsing.
IMAP has got some advantages over POP3 cause messages are stored
directly on the mail server and you should be able to get parts
without downloading the whole message.
If you are looking to get SMSs you must have a direct connection to a
SMSC gateway or an access to a SMS aggregator like Clickatell, MBlox
or many others.

Massimo

Email processing

[Joe Beharriell]

I'm currently working on custom-built CMS that will be used to power a
local community website.

Two of the biggest requests we've had for the new system are API
support (quite a ways down our upcoming features list, but coming
nonetheless) to allow posting from third-party applications and
widgets, and posting via email (or SMS, though we'd be quite content
with just email).

Has anyone worked with processing inbound email messages through
Django? If so, can you offer any tips, tricks, or examples that may
help me with developing this further?

Any information would be greatly appreciated.

Joe

Re: Avoiding HTTP 301 code using mod_python [SOLVED]

[Miguel Filho]

Well folks, with webfaction's support huge help, problem solved.

The responsible for adding the port to the URL is: mod_dir!

http://httpd.apache.org/docs/2.0/mod/mod_dir.html

Quoting the documentation:
"Provides for "trailing slash" redirects and serving directory index files"

So mod_dir was returning the URL with the port, before even Django
touches the URL.

Disabling mod_dir solves the problem, and now the slash is appended
correctly by CommonMiddleware.

Thanks again for Webfaction's great support.

The Django auth module is just a standard Django app.  If you
look in django/contrib/auth/models.py you'll see that the
User.username field is defined with a validator_list of
"[validators.isAlphaNumeric]".

In theory, you should be able to remove this validator to allow
for any random characters your users want to masochistically
choose.  I don't know if there are any ripple-down effects of
this, so you'll want to test the results.  My first hunting would
be for places that a username is validated with a regexp, and
ensure that it matches whatever validator your username's
CharField describes.

I think what I am trying to do is getting tangled up in a big ball of problem, 
and what I am looking for might be a simple fix. (or even working except for a 
bug in the admin UI.)

What follows is an attempt to isolate my problem from a bigger problem, which 
will also help with the bigger problem.

I just read over http://code.djangoproject.com/wiki/ModelInheritance and 
http://groups.google.com/group/django-developers/browse_thread/thread/1bc01ee32cfb7374/84b64c625cd1b402?tvc=2=Model+Inheritance#84b64c625cd1b402

I see a design methodology problem: there are at least 3 problems (or features) 
trying to be addressed and I think they are separate enough problems to have 
separate solutions.

I see more than one reasonable solution proposed.  Each has something to offer 
the developer, not mutually exclusive, and can even work in conjunction.   I 
think breaking ModelInheritance into well defined parts is important.

looking at my problem:
class abMessage(models.Model):
 to = models.ForeignKey(User, related_name = "messages_received")
 body = models.TextField()

class message(msg.models.abMessage):
 status = models.CharField(maxlength=1)

The problem/solution I am looking for:  abstract base, concrete subclass, 
subclass is persisted in one table in the db.  Yet this is the one case that 
was 
listed as "I am not implementing the "everything in one table" storage model." 
seems to me this should be one of the first things done, given how easy it is 
compared to the other solutions discussed.

"(1) What notation to use to declare a class as abstract?"

I think one of the problems trying to be solved here is: how do we keep 
django's 
syncdb, Admin UI and such from 'finding' such a class and trying to create a 
persistence for it.  This problem may exist in non ModelInheritance situations 
too, making it part of the ModelInheritance problem may limit the usefulness of 
the solution.

Usernames with spaces?

[[EMAIL PROTECTED]]

I've noticed that within the admin interface, if you try to edit or
add a username that has spaces in it, you get a validation error
stating that there can be no spaces in usernames. However, if I edit
the actual table data manually and  try to login or perform other
actions, everything seems to work fine. This seems to suggest that
there might not be any problem with spaces in usernames. Is there a
configuration directive for settings.py to allow spaces in usernames?
Is there any way that one could be added if there isn't already?

I've been building a MUD server with Django, so it'd be a really big
plus to allow this flexibility for usernames, since few people
actually want an underscore instead of a space, and I'd rather not
have to manually butcher the names (as that may confuse some, and it's
just sloppy).

# settings.py
...
DATABASE_ENGINE = 'sqlite3'   # 'postgresql', 'mysql', 'sqlite3' or 'ado_mssql'.
DATABASE_NAME = 'foo'
...

That is all you need (for DATABASE settings)  syncdb will create the database 
for you (called 'foo' in your  project dir.  which is fine for now.)

All that other stuff postdd is correct, but probably over your head at this 
point, so don't worry about it if you didn't understand.

Best Practice for translating db-stored values

[Panos Laganakos]

Using gettext_lazy, is the way to go, for marking models and fields
for translation.

Is there some general suggestion we're to follow, for translating
values stored in the db?

ie, let's say it's a model:

class Furniture(models.Model):
name = models.CharField(_('name'), maxlength=25)

If the app supports more than one language, how are we to get the
translated versions of a value, ie:

>>> furniture = Furniture.objects.get(id=1)
>>> car.name
>>> 'chair'

should I define a translation variable so I'll be able to get the
translated version from the template?

Adding a new field just for name_another_lang, sounds like overkill,
not extendable.

newforms: bound forms and prefix parameters

[arthur debert]

Hi Folks,

While implementing a form with edit inline like functionality, I've
hit a wall. In order to tell apart each inline model, I am using the
"prefix" parameter to instantiate the form. It works, but if it's a
bound form (whether from instance or getting values from a dict), if I
pass it a prefix, the rendered form shows empty values. This is easy
to test:

def test_prefix(request):
 f = forms.form_for_instance(request.user)(prefix="user_1")
 return render_to_response("test.html", {"f":f})

but if I omit the prefix such as in
f = forms.form_for_instance(request.user)()
the form renders correctly. (the html inputs show the right value)

Is there a catch here? I am sure this works, since the newforms-admin
must be using prefix to avoid name clashes when retrieving data from
the form.

Thanks,
Arthur

If this is the case, it means you're using Django to serve media,
which you shouldn't do if you can avoid it.  Django is for dynamic
stuff, and media is generally static.

Change your server config, and media will be a lot faster.

While I understand the menu is somewhat dynamic, you might consider
making this a template tag that does it's own caching:

Re: URL design for security?

The simple answer is "don't put anything sensitive in the URL".
In this case, that would mean not exposing things like SSNs in
the URL.  Since the teacher_id/student_id isn't sensitive,
they're fine in the URL.  However, you don't want people
accessing these URLs if they're not permitted to access them.

Enter Django's contrib.auth module.

Using Django's built-in "auth" module, it's dead-easy to do and
allows you to decorate your views with "login_required".  For
some example code, I'm just guessing at your models, but if one
student can have more than one teacher (as is often the case),
you'd have a M2M relationship between them.  However, if grades
are related to this relationship, you'd have to jockey the M2M
yourself.

I assume models like

# models.py
class Teacher(Model):
  user_id = ForeignKey(auth.User)
  # rest of definition

class Student(Model):
  # definition

class Class(Model): # don't know if this name is bad
  student = ForeignKey(Student, related_name='classes')
  teacher = ForeignKey(Teacher, related_name='classes')
  # rest of definition

class Grades(Model):
  class = ForeignKey(Class)
  grade = CharField(...)



# views.py
from django.contrib.auth.decorators import login_required
from django.shortcuts import get_object_or_404

@login_required
dev view_grades(request, student_id):
  # you don't need the teacher's ID in the URL
  # because they're linked to the request.user
  # the query would then look something like this
  try:
student_id = int(student_id)
  except:
raise Http404
  this_teachers_students = \
Student.objects.select_related().filter(
  classes__teacher__user_id =
  request.user.id
  )
  student = get_object_or_404(
this_teachers_students,
student_id
)
  ...


If the user isn't logged in and tries to request the view, they
get redirected to the login form.

If the user is logged in, but doesn't teach this student, they
should get a 404, because for them, this student doesn't exist.
You could customize it and return a more truthful HTTP error such
as a 403 (Forbidden) because the object might or might not be
found, but either way, they're not permitted to go poking around
here.

I second Christian's suggestion of using sqlite for its
minimal-fuss configuration (the OS permissions for the
web-server/django process on the database file are the
permissions you get).  It even has a ":memory:" database which is
handy for testing purposes (never touching a file).

I would add a small caveat to "painlessly":  it's painless unless
you try and monkey with the underlying SQL through either an
extra() call or hacking the ORM, both of which I do far too
regularly.  If you mess with either of these more obscure corners
of Django (okay, the extra() isn't obscured as it's right there
in the docs, but not many folks seem to know about it or use it),
you just have to be careful that your SQL is portable across the
various servers you expect to support.

However, if you avoid touching DB specific code, the Django ORM
does a rather good job of abstracting most of this stuff away so
your code becomes portable across DB engines.

Sure you can. You might want to look at sqlite, as it's the easiest to 
set up. You can painlessly switch to a "better" database engine when 
going to production, though sqlite does quite well the job, even in 
production.

Updating multiple rows with Django DB API?

[Steven Hilton]

I'm working on a web app where if a particular conditions is met in
particular object, a number of objects in another class/table need to
be altered. Basically a trigger, but I'm trying to keep all my logic
in the app for the time being. I'm wondering if there's a way to do
this with the Django DB API w/o falling back to raw sql.

A basic example is:

table foo
---
id
name
level


table bar
-
id
name
foo_id
switch


When foo.level drops to zero, I need to flip bar.switch like so...

update bar set switch = 0 where foo_id = foo.id and switch = 1

I could be updating any number of rows in bar. I want to do this
without do a select on bar.

Do I need to drop to raw sql, or have I missed this part of the Django
documentation?

Thanks for any feedback.

Re: JavaScript in template

[skam]

It's better to have the MEDIA_URL settings available in the request
context. Write your own template context processor, so you could have
{{ media_url }}/js/foo.js instead of hardcoding urls in templates. If
you need to serve admin media from a separate server or change media
directory you'll be able to change only the MEDIA_URL setting.

URL design for security?

[Rogelio]

Hi,

I'm starting to write a grade book type application.  There will be
many teachers that will be logging in to access their student
records.  The student record will contain student grades and sensitive
info such as student ID number.  In the model each teacher will have a
primary key (pk) and each student will have a primary key.  So if
teacher (with pk=21) logs in and wants to update the grade for student
(pk=197), the URL I'm calling to retrieve that view is "/grades/
21/197" (ie, on the teacher page there would be a list of student
names each being an  as shown).   I feel like
by using this scheme
I'm giving away too much info in the URL.  Some other teacher (or
person) who is NOT teacher (pk=21)
could just enter that URL and look at some other teacher's grades just
by "guessing" what pk to
plug into the URL.  What if the student pk was actually his SSN, then
I wouldn't want that as part of the URL for sure.

So my newbie question is:  Is there a way a better way to design/
obfuscate the URL scheme when dealing with sensitive information?   I
know once I get some sort of authentication in place that will help,
but the idea of showing sensitive info in a URL still has me
concerned.

If the host does not offer Python, you cannot use a Python-based framework.

For anything other than a personal site, I recommend having at least a
VPS or dedicated server; for anyone doing business on the web, there
shouldn't even be any question about this, no matter what technology's
being used -- the level of flexibility offered by dedicated hosting
costs money, but is well worth it.

Back when I was freelancing, the way I explained hosting to clients
was like this:

Your web site is how you present yourself to the world. If you were
running a business with a physical office, you certainly wouldn't
expect to find free office space or a free retail location -- you'd
expect to pay money to rent space, and you'd understand that the
quality of that location will impact the price. And if you want to be
successful, you'll invest some money up-front to have space in a
well-maintained building with a good location.

Free or cheap web hosts, in this analogy, are the online equivalent of
run-down buildings in bad parts of town; no matter how hard you work,
the limitations of the location are always going to be apparent to
your customers and are always going to hinder you in offering them the
best experience. So just as you'd invest more money to get a nicer
real-world location for a business, you'll want to invest more money
to get a higher quality hosting service; the increased flexibility it
offers in terms of improving visitor/customer experience will quickly
pay back the cost of the hosting, and then some.

Re: installation issues

[Carl Karsten]

Ok, getting somewhere.  That is the dir that needs to know about django.

Next we need to know where django is, and 'install' that into the site-packages 
dir.  'install' is just a link, .pth file or putting django directly in that 
dir.  I recommend the link.

more details are here:
http://www.djangoproject.com/documentation/install/#install-the-django-code

if you still have problems, post the following:
1. What version of django you want (official release, or development version.)
2. Where the django code is
3. what django references are currently in your site-packages dir.

For #3, do  ls -ld django* in your site-packages dir, like this:

[EMAIL PROTECTED]:~$ python -c "from distutils.sysconfig import get_python_lib; 
print 
get_python_lib()"
/usr/lib/python2.5/site-packages

[EMAIL PROTECTED]:~$ cd /usr/lib/python2.5/site-packages

using middleware vs. context_processors: best practice?

[Amit Ramon]

Hello,

I'm working in a multilingual site, for which I have the following two 
requirements:
1. The language to use for content and ui is derived from the url.
2. All pages (rendered by different views) have a "constant" part - menu, 
title, etc. The menu is stored in the database (it's simply another model), 
and I have a function that creates the menu and I pass it to the template in 
the extra_context.

Following a tip from Malcolm (thanks!), in order not to repeat code for doing 
1 in each and every view, I created a custom middleware that sets the 
language in its process_view method.

I thought I would do the same for 2, but I just found out that I can also use 
a custom context_processor for it, which seems more natural for the case.

Anyway, I have some questions:
1. The language must be set before creating the menu (so the menu will be in 
the correct language). I assume that middleware gets called before context 
processors. Am I right here?
2. I noticed that the middleware is called for every request - this means that 
if I access a page which loads additional stuff - for example images, or css 
files, the middleware is called multiple times. At least in my case, I only 
need my custom middleware to be called once for every page. Am I paying 
anything by this behavior (performance wise, of course)?
3. A more general question: the menu changes very rarely. How my design 
affects performance? I mean, is there a db access for every page, or is there 
some caching? I'm not too familiar with what's going on behind the scenes, 
and I would appreciate if someone would shed some light on this issue.

Sorry for the long story...

Thanks,

Amit

Thanks, I already saw that list, it's useful when you build your own
site and searching for a hosting service.
It's not so useful for me because my main job is to build web-sites
for costumers that already have some of hosting service, the chance
that they use a hosting service from that list is very low,  almost
zero.

That's means that I can't use Django or any other python-based
framework for my job ?
I'm asking all the programmers that work for other people, how do you
work with Django?

>

If you don't want to use ajax you can either use a form as normal to 
submit it and then issue a redirect at the server side to the new page 
or call a javascript function to issue a window.Location to fetch a new 
page or use image buttons that are inside a HTML link etc. It's really 
up to you how you want to "load" the new page.

If you just want to fetch more data using ajax then you could use 
something like: (this is just a simple test example from my code)

$("#newfeaturesave").click(function() {
   var newfeat = $("#id_name").val();
   var newval  = $("#id_value").val();
   var staffid = $("#id_staffid").val();
   $.ajax({
   url:"/stafffeature/add/"+staffid+"/",
   type: "POST",
   datatype: "html",
   data: {name:newfeat,value:newval},
   success: function(row){
   $("#featuretable tbody tr:last").after(row);
   $("#featuretable tbody tr:last").prev().remove();
   $("#featuretable tfoot").show();
   $("#featuretable tbody tr:last 
.griddelbtn").click(function(){
   dofeaturedelete(this);
   });
   $("#featuretable tbody tr:last 
.grideditbtn").click(function(){
   dofeatureedit(this);
});
   stripetable("#featuretable");
   },
   error: function(XReq, errs, errobj){
   alert(XReq.statusText+'\r\n'+XReq.responseText);
   }
 });
});

Of course you will want to read the JQuery docs to find all the 
possibilites for your situation.

Regards,
Gary.

Well, once I'll feel comfortable with django and js, then probably, but
not at the moment.

I've got that done now.

What I'm looking for now is, how to redirect to a different page with
the button, and sending to the page (django view) the id number.

I am really not sure of this question but according to what

it is possible to deploy without python (I might be wrong as well).

I've been searching for free hosting services that supports
Mod_Python, I never find one.
In addition, there are few non-free hosting services that supports it.

so, let's say I'm building a Django based site for my costumer, the
costumer knows nothing about computers so he don't care about the
programming language, however,
in most cases the hosting service he uses won't allow python scripts.
thats a problem.

python - OFF ]

Make the following change in your urls.py file.
(r'^js/(?P.*)$', 'django.views.static.serve',{'document_root': '/
home/django/work/fw/media/'})

and replace in the base.html

Do not place the JS files in the ADMIN_MEDIA_PREFIX files. It is
specifically for files needed by the admin section.

I am not expert neither in Jail or FreeBSD, but it seems obvious that
they
did not configured "random" device into jail. So I think you shoul ask
them
to include support for random into jail.

May be even simple thing like:
mknod dev/random c 1 8

under 'root' of this jail will help you, but I am not sure and
probably you can try and if not works,
ask FreeBSD expert.
