Baylink: You can put a venv anywhere you want.

Yeah, I just know where I want it, and $HOME wasn't it. :-)

Baylink: virtualenv-wrapper is a really nice tool for managing your venvs

Baylink: put this in your shell rcfile http://dpaste.com/1322405/

what would be a relatively painless way of grabbing a URI string from a template?

what? introspectr3 ?

fission6: trying to grab URI string from within a template. is that possible?

i don't know what you mean and what you're ultimately trying to do/solve

I'm super confused

hmmm

I can't import the RegistrationView from registration

http://www.mydjangoproj.com/**I NEED TO GRAB THIS STRING***/somestring/someotherstring

Cheekio: what happens

oh you want to grab a parameter in the url pattern introspectr3 ?

hey fission6: my imports never work. "from registration.backends.default.views import RegistrationView" just gives me errors

yes please!

it gives me "No module named backends.default.views"

introspectr3: https://docs.djangoproject.com/en/dev/topics/ht...

Cheekio: is it in your installed Apps

django-registration is, yes

pip freeze gives me django-registration 1.0 and django-registration-defaults 0.3

and its in your django installed apps

can you do python manage.py shell

import registration

no, I can't

no wiat

I can

import registration works

and the default registration system works

introspectr3: What are you actually trying to do?

Oh, not in templates at all.

Cheekio: there is no reason else i can think off

of

if I'm in a subdirectory, do I need to write 'import ..registration.backends' or something?

you should be able to import everything with an absolute path

you said you were able to import

when you did

pyton manage.py shell

yes, I can

although I'm trying to import the registration backend from within another app

Hey, I want to annotate the division of two Sums, and then be able to order by that. I tried using extra, which gives me the exact SQL I need... apart from a single GROUP BY. http://dpaste.com/1322407/ : I'd rather make a custom aggregate function or something, but I don't think I can get the queryset to do two separate lookups without some changes to the Query class. If I try and edit the queries group_by field, it throws all the aggre

gates into the group by...

are you working in two terminals Cheekio and like don't have your virtualenv active or something silly

no, I'm using the same terminal :D

does the order in settings.py matter?

Only for lists and the like

yes sometimes

And imports.

Nervosa how many rows are you aggregating over

fission6: It's an unknown. I'm currently running on fake data until we move to a real system.

Lemme get a row count...

still no dice

You can assume lots. Millions.

ah ok

the import line works fine in manage.py shell, but doesn't work in-app.

greetings, djangonauts. The following question references this paste: https://dpaste.de/xeJ2Z/

performing what I believe to be an identical query against a mysql database directly and then again using a raw queryset returns different results

apologies, bad paste above. Here's the fixed one: https://dpaste.de/m8Ofw/

I think I figured it out

I included an import statement in my project/urls.py file

where is the IN stuff cewing IN ('Elephants', 'French Bread', 'Tonsils'))

does it work now cheekio

fission6: see the updated post, sorry :(

that's probably before the registration app takes hold, because it's not referenced yet

haha, no, not at all

User.objects.raw(sql, [param]) should return five users, but only two are returned

the two returned are the two that would be returned if I only used the second subselect

it's as if the UNION is not operative

cewing: You should be able to do that query using filter, I think.

it's got to be a matter of circular dependencies

cewing you can also double check the queries by turning on query logging an making sure they are indeed the same query hitting the same tables

fission6: that's a good idea

and schinkel, I'll try with a filter. It makes my head hurt even more than that sql, though :)

fission6, do you have any experience with subclassing from django-registration?

no really but it should be like subclassing anything else

although i do think I've done it with registration before actually

They moved everything over to class based views in the past few months

but all the how-to's are using the old django 1.4 compatible registration

I just want to add extra stuff to the /accounts/register page, so my url looks like "url(r'^accounts/register/$',MyView.as_view(),name='registration_register')"

but that means I need to import MyView, which subclasses the RegistrationView before it's added to the django environment

ok

schinckel: thanks, man, for talking me down from using .raw()

figured it out

I'm reading a book "Pro Django (2013)", and it says to refer to "The Definitive Guide to Django: Web Development Done Right (2009)" for the basics. I'm a bit confused, I'm told that old material for Django is not a good source, but this book released this year refers to the second book published in 2009. I'm guessing it is safe to assume that a book on Django from 2009 is still relevant and

won't develop poor habits?

The above reference from Pro Django is for those who need to learn the basics first

Pandee: the basics of django don't change *too* quickly

so the reasons for the djangobook being a bad learning source is because it was done poorly?

it's REALLY old ;)

oh lol

and a decent amount of what it covers in detail is now out of date
