Re: Reverse Lookup Failure on password change/reset views

[Peter]

Yep, that fixed it.  Thanks.

I still think it's wrong of django not to find it by view name though...

Thanks, after a bit I got hold of the field=Null items, which were appearing 
unexpectedly in an earlier queryset.

Re: django.contrib.auth and username's field size

[Ivan Voras]

Thanks, everyone!

While I'm here: is there a way to create additional db objects in the
syncdb phase? Specifically, I'd like to create some database VIEWs as
a means of avoding using raw queries in my code. Ideally, I would like
a way of specifying my own SQL which creates a Model's database object
(so I can do a CREATE VIEW instead of CREATE TABLE), or something like
that.

Error.

I've just set up a new view / url etc, which has quite a bit of processing
behind it.  When I click on the link for it, I get the "Connecting" message
for a few minutes, and then just "A server error has occurred. Please
contact the administrator." appears.  Is this a time out message?

Could be. But if you don't provide more information (i.e. detailed

I meant is there a more general way of doing something like:

red_things = queryset.filter(colour="red") # get red things

non_red_things = queryset - red_things # get all other things

Maybe this simply isn't possible in SQL.

How did you start your server? Using a command line such as "python

Somewhere you mush have a window showing this kind of information:

Advanced Tutorial (how to write reusable app), last step does not work

[Christian Erhardt]

Django is using a coding "style" called covention over configuration. That 
means that you don't have to configure every bit of your application instead a 
convention is used to determine where you have to place stuff so django finds 
and uses it. For the beginner it seems like django is using some sort of magic 
to connect erlverything together.
In your case, having read the tutorial a long time ago, you surely created a 
View class that is derived from the ListView base class. The convention here is 
that you create a template called _list.html. If you have a file 
with this name, the listview will use it for rendering. It seems the creation 
of this file is missing in the tutorial. But it is pretty straight forward if 
you look at the documentation of the listview base class.

Re: ImportError: No module named django.core.management

My first guess is that django is missing.

Re: .filter() and .exclude() don't add up

[Steve McConville]

Perhaps I'm not sure exactly what you mean by "more general", but I
was recommending something like

red_things = queryset.filter(Q(color="red"))
non_red_things = queryset.filter(~Q(color="red") | Q(color__isnull=True)

This will produce SQL like

SELECT * FROM queryset WHERE color IS 'red';
SELECT * FROM queryset WHERE color IS NOT 'red' OR color IS NULL;

The set non_red_things will be the complement of red_things.

Firstly, you can use Django's ability to invoke raw SQL as part of the
syncdb process:

https://docs.djangoproject.com/en/1.5/howto/initial-data/#providing-initial-sql-data

Although the examples in that documentation describe using INSERT
statements, you can issue any SQL statement you want.

Secondly, you could use South.

http://south.aeracode.org

South is a migration framework for Django -- it allows you to manage
changes in database schema, but you can also include creation of additional
views, indexes, etc as part of that process.

This error can also occur if the virtualenv is not actviated. Did you run 
``source bin/activate`` (or the appropriate ``workon`` command, in case you're 
using virtualenv-wrapper)? Does your shell prompt show the name of the 
virtualenv?

If the virtualenv is activated: is Django really installed in the virtualenv? 
What's the output of ``pip freeze|grep -i django`` (with the virtualenv being 
active)?

tinymce

[Karl Arunachal]

Hello,
I am not able to use the tinymce editor in my flat pages.
My tinymce is in this dir:
C:\Users\Kakar\Downloads\Compressed\tinymce\js\tinymce\tinymce.min.js

And in my template dir i have another admin folder for 'change_form.html',
just below this line:



i have added this line for tiymce:



tinyMCE.init({
mode: "textareas",
theme: "simple"
});


In my urls.py, i have added:

(r'^tiny_mce/(?P.*)$', 'django.views.static.serve',
{'document_root':'C:/Users/Kakar/Downloads/Compressed/tinymce/js/tinymce'}),

Please, point me out, where am doing wrong. I am learning from a book
'Practical Django Projects'.

Thank you.
