Re: redirect after post caches anchor?

[Tiago Serafim]

Hi Margie,

I misunderstood you first post. What I said is valid, but it doesn't relate
to your problem.

Now that I get it: FF scrolls back to the same position after a reload.

I don't know how to work around this issue unless you return a anchor
"#top"(like you did with the another one) and add an attribute id="top" on
your "body" tag.

HTH,

Re: redirect after post caches anchor?

[Margie]

Hi Tiago,

Thanks very much for your response.  So is there a way I can tell the
client that I don't want to retain the same anchor?  IE, tell the
client to act as it would act if the client had initiated a new GET?

Where would I find documentation on this?  Or not necessarily doc but
just something that discusses this problem.  My googling didn't turn
up much of anything but it seems like it would be a problem that
others have as well.

The built in templates and filters have formatted docstrings (``,

Where can I find information on this.

Example docstring:
def yesno(value, arg=None):
"""

None,
returns one of those strings accoding to the value:

``False``   ``"yeah,no,maybe"`` ``no``

``None````"yeah,no"``   ``"no"`` (converts None to
False

Hi,

This is the expected, as HTTP clients doesn't pass the #anchors to the

I believe the general reason for performing a query like this is to minimize
the number of queries that have to be performed.

What I think you want is select_related(). The docs don't mention ManyToMany
fields but for ForeignKey fields it looks like it does what you are looking
for. It's documented here:
http://docs.djangoproject.com/en/dev/ref/models/querysets/#id4

Updating request.POST

[koranthala]

Hi,
   I have the following scenario.
   I am creating a custom admin page for one of the models. I am
adding few extra fields. If the extra fields are set, then the user
does not need to set the model fields. An example is given below:

Model A:
val1 models.ForeignKey(A1)
val2 models.ForeignKey(A2)
val3 models.CharField()

Form F:
val_x_1 forms.CharField()

Now, on the add/change page for Model A, I am giving an option. It
would look like the following:

Add A:
--
val_x_1:[]
val2:   []

  OR

val1:   []
val2:   []
val3:   []

[Save] [Save and Add Another]

The user can either type in val1, val2 and val3 or he can put in
values in val_x_1 and val2 only, and my custom add_view should take
care of everything.

Now, the whole page is working fine. But, I am unable to update
request.POST to set up values for val1, val2 and val3 based on the
values val_x_1 and val2. I created a mutable copy and tried putting
that copy back to request.POST, but everytime I am getting the 'cant
adapt' error. The backend is PostgreSQL.

If I dont update request.POST, the form.validate would fail inside the
proper add_view. I cannot make it as blank=True straightaway because
if the val_x_1 and val2 is not updated by the user, he needs to update
mandatorily val1, val2 and val3.

Can anyone help me on this?

redirect after post caches anchor?

[Margie Roginski]

I'm seeing some strange behavior related to anchors that I can't
really explain.  I'm going to give an example of what I'm seeing and
I'm hoping that someone can point me in the right direction.

Let's say I do a post and my  views.py code that services the post
returns like this:

  return HttpResponseRedirect('/taskmanager/edit_task/12/
#comment_101')

(I am of course not hardcoding the redirect address - but have shown
it explictly here for clarity)

This correctly displays my /taskmanager/edit_task/12 page, taking me
part way down the page due to the #comment_101 anchor.

>From this url I do a second post.  The views.py code associated with
this second post returns like this:

return HttpResponseRedirect('/taskmanager/edit_task/12')  # note
no comment_101 anchor

I thought this should take me to the top of my /taskmanager/edit_task/
12 page, but instead it takes me to /taskmanager/edit_task/12/
#comment_101.  It's like the #comment_101 anchor is cached in some
way.

My runserver printouts from the second post and the get associated
with its redirect show this:

[12/Sep/2009 18:16:51] "POST /taskmanager/edit_task/12/ HTTP/1.1" 302
0
[12/Sep/2009 18:16:52] "GET /taskmanager/edit_task/12/ HTTP/1.1" 200
50904

So the #comment_101 is not there, yet it still appears in my firefox
browser.   Anyone know why this is?

Thanks,
Margie

It doesn't. Read instead:

  http://code.google.com/p/modwsgi/wiki/AccessControlMechanisms

This still will not help if wanting to secure pages using form/session
based login. Use the X-Accel-Redirect/X-Sendfile/Location response
headers instead as described elsewhere related to that future Django
patch.

Re: Load Templates from outside TEMPLATE_DIRS

[mviamari]

The template in question is to format my test results, and I didn't
want to have lump it in with the production templates, or have the
template directory permanently attached to the TEMPLATE_DIR

So instead I've just loaded a new settings file with a modified
TEMPLATE_DIR before I do my tests.  Works pretty well.

Thanks.

Complex Query Optimization

[Phil]

I am trying to minimize the database hits. Take this example...

from django.contrib.auth.models import User

class Group(models.Model):
# a bunch of fields here
user = models.ForeignKey(User, related_name="groups")

class Member(models.Model):
# a bunch of fields here
user = models.ForeignKey(User, related_name="members")
groups= models.ForeignKey(Invitation, related_name="members")

Basically the idea of the above is that given a user, you can fetch a
list of members. Or, given a group, you can fetch a list of members
belonging to that group.

In one of my templates, I would like to paginate based on the groups,
lets say 10 groups per page. But for each group displayed, I want to
also display each member. The groups will be small enough so this
won't be ridiculous. I feel confident than this can be done _without_
having to perform 11 queries per page (one for the groups, and then 1
for getting the members of each group). Am I correct? If so, how?

Mildly off topic, I am trying to figure out what exactly happens when
using MyModel.objects.all(). I understand that it is just an iterable
but, using the example of pagination, when you do Paginator
(MyModel.objects.all(), 10), is there no database hit until you get a
specific page, where it will only fetch the 10 for the page it needs?

What's the point of this query? What are you trying to achieve?

I believe Django will automatically do a left-join query if your
ForeignKey has null=False. But your question doesn't seem to be about
left join queries in general, it's about the specific case where you
join a table to itself. But without understanding why you'd want to do
what you're doing here, I can't answer.

You might be able to use the {% with %} tag to assign the first row to
another variable, and use that. Untested:

{% with row|first as first_row %}
{{ first_row.label }}
{% endwith %}

Otherwise, you'll need a custom template tag - luckily these are very
easy to write.

My mistake, you're right it's used in the comments framework. Brandon,
if you're using the built-in comments form, then set
COMMENTS_ALLOW_PROFANITIES to False and it should work.

Can I dereference a field in the output of a filter?

[W.P. McNeill]

I have a view that renders a table.  The "table" object is a list
rows, which are themselves lists of model objects.  These objects have
a parameter called label.

Inside the template

{{ object.label }}

render's an objects label and

{{ row|first }}

renders the first object in the row.

I want to be able to render the label of the first object in the row.
I want to write something like this

{{ row|first.label }}

but that doesn't work.  Is there equivalent syntax that does work
within the template markup language?

Your methodology seems to be "guess the syntax". Looking in the
documentation would be more fruitful. Or, do a search of this group,
as this question comes up regularly.

There are two ways of doing it - either use the {% cycle %} tag or use
{% if forloop.counter|divisible_by:2 %}

I use the contribs.comments module, and in its clean_comment method:

if settings.COMMENTS_ALLOW_PROFANITIES == False:
bad_words = [w for w in settings.PROFANITIES_LIST if w in
comment.lower()]
if bad_words:



The file is in:

It came for free, so I never stepped through this code.

Make a bold row in a table

Django 1.0.2   In the following template I intend to make rows that
have an empty second column bold.  Hence trying 2 in row.  My syntax

also.

{% extends "base.html" %}
{% block content %}


Agent summary report
 The most recent listing for each property listed within the past
12 weeks


   
   
   Address
   Date
   Price
   Method
   Agent
 
   Mobile
   
   
   {% for row in listings %}

{% for item in row %}
{{ item }}
{% endfor %}


   {% endfor %}

Re: Django and CouchDB

[Suno Ano]

Hi folks,

I am too very fond of non-SQL databases (no fixed schema, built-in
replication, built-in webserver, RESTful API, etc.). So far, in order to
use Django with CouchDB here is what I have come across so far

 - 
http://lethain.com/entry/2008/aug/18/an-introduction-to-using-couchdb-with-django/
 - http://couchdbkit.org/docs/formalchemy.html
 - http://couchdbkit.org/docs/django-extension.html

>From my pov, having native support for non-SQL databases with Django
would totally rock!

Initially I was very skeptical too (I have been using
MySQL/PostgreSQL/Oracle for more than five years now) but after I got to
know CouchDB, I am convinced that using a non-SQL database is often a
lot better (save me lot of time, easier data modeling, way better for
web apps than SQL databases, etc.).

ImageField anti-duplication

[A. Rossi]

I have an application where users can upload images, then the image is
renamed to a SHA256 hash of the file's contents.
Here is the relevant snippet of the model

class ImagePost(Post):
def imgurl(self, filename):
import hashlib, os.path
extension = os.path.splitext(filename)
self.image.seek(0)
return "images/%s%s" % (hashlib.sha256(self.image.read
(self.image.size)).hexdigest(), extension[1])

image = models.ImageField(upload_to=imgurl, blank=True)


what I am attempting to do is, if a user uploads an image that already
exists (i.e. the two files have the exact same SHA256 hash) I want to
have the ImageField point to the already existing file, rather than
save the newly uploaded one. I have tried a couple things that didn't
work, and the default behavior when dealing with files of the same
name is to append an extra _ to the end of the name, before the
extension.

I feel like I'm on the cusp of figuring this out, but I'm stuck. Also,
would I put the code for this into the imgurl() function, create a
custom storage object, in the view(s) directly?

Thank you for your help.

I actually think that this is a left-over setting from old code that
has since been removed. The profanities checker was one of the
oldforms validators, which were removed before version 1.0. So the
setting is probably deprecated.
