Disk I/O Error

I'm getting a DatabaseError, looking like this:

Django Version: 1.3
Exception Type: DatabaseError
Exception Value: disk I/O error
Exception Location: /usr/local/lib/python2.6/dist-packages/django/db/
backends/sqlite3/base.py in execute, line 234

whenever I try to read or write to any of the databases associated
with any of the websites on one of our servers. The fact that all
these websites work locally, but not in their live versions seems to
suggest to me that something has gone wrong on the server, rather than
with django, but I thought I'd better ask and see if any one has had
any similar issues. I'm running python 2.6.6, django 1.3 and they're
on a Linux server.

Re: new formwizard - how to pass data between forms

Awesome! Let me know how it works out for you. I'll probably be giving it a try shortly as well. Thanks for sharing the good information.

Hey Kurtis,

thanks for your answer.

I think hidden fields were used in the old implementation.
At least the release notes for 1.4 say:
"It features a pluggable storage API and doesn't require the wizard to
pass around hidden fields for every previous step."
But checking the example apps (https://github.com/stephrdev/django-
formwizard/blob/master/test_project/testapp2/views.py#L20) i found
what i was looking for:
get_cleaned_data_for_step()

It does exactly what i need :-)

Thanks. I just set LANG=en_US.UTF-8 (from empty), dropped the
auth_user & django_site tables for them to be recreated, ran "manage
syncdb", and now everything works. Apparently it's a new quirk of
Django, earlier releases didn't care if LANG was set.

Re: Why are my two django objects of the same type behaving differently?

Somebody answered this

Works well.

Re: Django - tutorial part 2 problem - Permission denied when attempting to save file

It looks like you don't have write permissions to the "base_site.html"
file, or if the file doesn't exist, than you likely don't have proper
permissions for the enclosing folder. What is the full path of the file
you're attempting to edit?

Django - tutorial part 2 problem - Permission denied when attempting to save file

Got this error
Ran into this as part of the Django tutorial (part 2) very close to
the bottom .... an attempt to change the page header/title.

"There was an error attempting to save 'base_site.html':Permission
denied"

when trying to save the file below (copied from django source code)

{% extends "admin/base.html" %}
{% load i18n %}

{% block title %}{{ title }} | {% trans 'Django site admin' %}{%
endblock %}

{% block branding %}
<h1 id="site-name">{% trans 'Django administration' %}</h1>

any thoughts?

One way to fix it would be to get a locale properly set on your machine. Another would be to read that ticket and try patching your Django with one of the patches attached there.

Unfortunately, we can't give you an estimate of when more tutorials
will land -- the only real answer is "when they're written".

One of the embarrasing things about Django's docs is that Tutorial 4
ends with "More tutorials coming soon". It said when *I* started using
Django -- 6 years ago.

This is definitely something that I would like to see addressed;
however, good tutorials are time consuming to write, and nobody has
volunteered to write one (there is a draft for a Tutorial 5 that has
been waiting for review for a couple of months, however).

All the topics you list, and many many more, would be excellent
candidates for tutorials. If *anyone* wants to get started with
contributing to Django, writing tutorials would be a great way to help
out.

Yours,

Re: I can't activate the admin site

Thank you all.
I'm using Django 1.3
I may need to rewrite the file sites.py
I'm sure I did not change anything in that file.

Re: TabularInline "Add another" link not clickable

This CSS tweak fixed it:

Re: Django Standalone Template

Yeah. Tuples catch a lot of folks. Just because the empty tuple is
spelled () .

At the risk of telling you something that you already know:

The app_directories_ loader should pull this stuff in for you, so long as
django.contrib.admin is in INSTALLED_APPS. Usually TEMPLATE_DIRS
is used to include a "templates" directory in your project root.

Re: Django Standalone Template

Try putting a comma at the end of the TEMPLATE_DIRS line.

Parentheses do not the tuple make. It's the comma. An expression
surrounded by parentheses is just the expression, so you're trying to
use each letter of your setting as a directory, I believe.

I take it you're not using the app directories loader?

Re: Django Standalone Template

I think that you have too many "admin"s. Try:

TEMPLATE_DIRS=('C:/Python26/Lib/site-packages/django/contrib/admin/templates')

Yes, that's what I was reading.

So, my setting TEMPLATE_DIRS here to the actual subdirectory would not work?

TEMPLATE_DIRS=('C:/Python26/Lib/site-packages/django/contrib/admin/templates/admin')

I used this as an example to point to some templates that are known to
work, rather than point to my own templates that don't work either. If I
go into the Django code and print out the directory that's being
searched, I see the correct directory there, so I don't know why things
are failing. Maybe I'm just not instantiating things correctly?

In any case, I tried your suggestion, but still no luck:

>>> loader.get_template('admin/base.html')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "django/template/loader.py", line 164, in get_template
template, origin = find_template(template_name)
File "django/template/loader.py", line 145, in find_template
raise TemplateDoesNotExist(name)
django.template.base.TemplateDoesNotExist: admin/base.html

(I also tried without manually setting TEMPLATE_DIRS, but just ran
django.conf.settings.configure(), still to no avail.)

Anyone, any ideas? I'm completely new to Django, but I've not been
working in Python lately either, so it could just be a Python mistake on
my part.

Hi Django folks -

I'm new to Django, and I just want to use the template system now,
independent of the rest of Django. But I can't get it to see a

Re: Dynamic URLs or creating querysets from your URL paths.

Sure you could do that. It's called using XML Transformations (XSLT), Javascript Templatating Engines, or a number of other approaches.

Django does this with its Template Engine. The reason this isn't completely ran on the Client-Side is because it would be slower, difficult to cache, and dependent upon some specific Client-Side technologies.

Django lets you easily override this behavior. For example, there's documentation on using alternative Templating Engines. You could apply the same methodology to using Client-Side Templating Engines (written in Javascript), or even just displaying XML w/ XSLT using the Browser's Transformation Engine. I'm not really the most experienced person when it comes to Client-Side templates but I'm sure there's a lot out there in Google Land.

Ideally when a user requests a webpage from my server, I should deliver the presentation layer to them, along with the information they require to perform an API lookup. From then on they can query my server using the same REST api a phone app would use. This would mean that all the information from EVERY device accessing my website comes from the same api. This is much better then my existing setup, where I might have an API for an app to accompany my site, but I also have a jungle of urls and views to enable a web browser use my site

Dynamic URLs or creating querysets from your URL paths.

I'm creating a CMS using django-cms and some custom plugins. Everytime I do this I get sick or writing the same views time and time again.

Quick example, I have a Project model that can have one or more Categories, Tags and Clients:

class Project(...)

categories = models.ManyToManyField(Category)

tags = models.ManyToManyField(Tag)

clients = models.ManyToManyField(Client)

I want the user to be able to browse my projects by a certain category, or tag or client. So my urls would be something like:

url(r'^projects/category/(?P<slug>[-w]+)/$', ...

url(r'^projects/partner/(?P<slug>[-w]+)/$', ...

url(r'^projects/client/(?P<slug>[-w]+)/$', ...

allowing me to see all projects for particular relationships, and maybe

url(r'^projects/category/$', ...

url(r'^projects/partner/$', ...

url(r'^projects/client/$', ...

to list all categories, partners and clients.

This seems totally anti-DRY (WET?) to me. I'd like to be able to dynamically create the query based on what the URL path is, instead of having to manually link the URL paths to the correct queries via views as it stands at the moment. So retrieve the correct model based on what path is supplied - somewhat like a REST API call. Does anyone have any thoughts on this approach, or Is there anything out there that caters for this?

tl;dr - the user got bored waiting, pressed 'stop' on their browser.

Although that's almost always true, it *is* possible to see "request data read error" on WSGI that isn't caused by the user hitting stop. See for example the ModWSGI FAQ.

Re: Django tutorial hasn't received an update for 1.3

Hi,

If you've figured this stuff out, how about writing some of the tutorial yourself and submitting a patch?

Trying to teach someone else is the best way to figure out if you really understand something, and you'd be contributing to keeping the Django documentation great.

I keep checking the tutorial page for version 1.3 hoping to see some
new content related to the class-based views or at least some of the
promised future tutorials. The tutorial still has the function-based
views, and no new updates since I first went through it on the 1.2
release.

I know the function views work in 1.3, but shouldn't the tutorial be
using the latest features included in 1.3 so that new users coming to
Django begin learning the newest features, such as class-based views.

I'm still a dinosaur and using Django 1.2 and haven't yet dived into
class-based views, and when I do, I would love a great tutorial on how
to proceed. I plan on learning Django 1.3's newest features very soon
to keep myself up to speed and see if my current apps are fully
compatible.

Are there any updates on when we will see the following new tutorial
sections:
- Advanced form processing
- Using the RSS framework
- Using the cache framework
- Using the comments framework
- Advanced admin features: Permissions
- Advanced admin features: Custom JavaScript

I figured out most of this on my own, as they are pretty
straightforward, still haven't dived into custom javascript in the
admin yet.

When the going gets complicated, my simple mind reaches for python.
Maybe a custom template filter?

no I wouldn't expect the indentation problem to be located in django code.

Why are my two django objects of the same type behaving differently?

Help!

I have two objects that i have created using different techniques in
django;

>>> from django.contrib.contenttypes.models import ContentType
>>> from myproject.models import Building

Method A

>>> content_type = ContentType.objects.get(app_label='myproject', model='Building')

>>> content_class = content_type.model_class()

>>> content_query = content_class.objects.raw("Select * from pms_building where name like '%build%' ")

>>> type(content_query)

<class 'django.db.models.query.RawQuerySet'>
>>> content_query[0]
# error ....
# Attribute: 'str' object has no attribute 'items'

Method B

>>> bld = Building.objects.raw("Select * from pms_building where name like '%build%' ")

>>> type(bld)

>>>bld[0]
<Building: Building A>

My question is why are the two objects of the same type behaving
differently?

Re: django-easyfilters for filtering data in a view

If anyone else is having trouble here, my problem was in passing the
template when loaded from an external file--specifying the template
inline worked fine for me.

The context variables are provided in the documentation.

Good luck

You just installed Django's auth system, which means you don't have
any superusers defined.
Would you like to create one now? (yes/no): yes

Because of this, I can't use the admin app:
