DjangoBot: #django

(Writing an explanation on dpaste.com, one sec)

hello

when using sqlite

does the database_name have to be a full path, or can it be relative to the settings.py file?

mxmasster full path

how should I implement different roles for my users? (i.e. Students should have only one Clasroom, while Teachers might have more than one Classroom)

mxmasster it probably can be relative, but not to the settings.py file

i.e. i want to specify ../project.db

Should I make a Student model and a Teacher model?

or just project.db

mxmasster predicting *where* it would be relative to is the hard part, and would depend on your deployment

mmm, caching was easy to implement

relative to invocation, but full is recommended

delicious

is there a shorthand for {% if foo %}{{ foo }}{% endif %} ?

Zalamander: okay - so if i am checking in the settings.py file, what is the recommended practice

{{ foo }} :)

for multiple developers

There: http://dpaste.com/38157/

A little better I guess

my home directory has a different path than other ppl obvioulsy

mxmasster use a full path, but you can find it dynamically, by examining os.path.abspath(__file__) inside settings.py.

triton-mx: use permissions

But generic relations are pretty heavy on the database and adds complexity I'm not very fond of.

mxmasster something like: os.path.join(os.path.dirname(os.path.abspath(__file__)), os.pardir, 'project.db')

I would, in an ideal world, only have to perform 1 query (but that wouldn't be easy as some of the models have m2m relationships)

dpaste of the same http://www.djangosnippets.org/snippets/445/

rather djangosnippet

But at-least keep the amount of queries down and have a managable solution.

thanks

antonr, I think it's not a permissions question, a Teacher has different filed from a Student ... how can I implement this?

triton-mx: are teachers and students users in the system or just objects?

they should be different kind of users

then make a user group for teachers and a user group for students

by the way

i've just started developing my first django site

an User that is a Student should have a one-to-one realtation with a Classroom, but a Teacher should have a one-to-may relation with Classroom

and i was thinking about using the already existent user table and create another model for the extra user fields i want for my users

is that a good way to do things ?

s3phiroth, you sould use a Profile

anyone else having problems with the latest newforms-admin branch and USE_I18N = True?

mmm...and what are those ?

triton-mx: oh i kind of misunderstood, use foreignkey and manytomany fields

oh

is it possible to include a file from settings.py that would override the settings.py values?

s3phiroth, a model with a foreignKey named "user"

triton-mx: already found it. i'll look into it later

thanks :)

masida: what are you seeing?

triton-mx: oh...but that's what i'm doing

brosner: there seems to be going something wrong with the new auth code (which is ported to newforms)

masida: continue...

luris: as long as it is only does something while someone edits/writes a comment/blog post/whatever .. it shouldn't matter to much if it's heavy

antonr, so I have to make a Student model and a Teacher model?

s3phiroth, you are doing well :)

if you consider optimizing any parts of the code, than those that get called million times a day

*the

n

Uz_: hopefully comments will :)

hehe, nice :)

and i hadn't even read the authentication documentation properly

But I think I'll go with lan B

plan

luris: well they will be called more often, that still doesn't compare to normal GET requests

but that just felt like something logical to do

brosner: http://dpaste.com/38162/

don't know exactly what's going wrong, because somewhere an import can't be made

only thing i know is that it doesn't happen when USE_I18N = False

note: i'm importing the auth User model in my own models.py

triton-mx: then you use user groups. in form validation you should check whether the user is a teacher or not. if the user is a student and already has a classroom, the form will give an error

masida it's possible you're creating a circular definition somewhere

triton-mx: you can also hook the same check to the save() in your model

antonr, should I subclass the save method?

Zalamander: yeah, it must be something like that, but it worked a week ago... (before newforms-admin used newforms for the auth module)

triton-mx: that's what i'm suggesting

antonr, ok, I thought I was not allowed to overwrite the save method

hello, anyone can tell me how I can print the SQL a queryset is going to use?

masida: ok, i think i know what's up. i won't be able to fix it right now though

brosner: ok, no problem, are you working on newforms-admin?

I need to output a queryset SQL to troubleshoot a problem

masida: yeah, try the patch at #6718 and let me know if that fixes it

brosner: thanks, that works!

does anyone know?

Carolina: read the faq

I read the database api and coudn't find anything

triton-mx: it's quite common, check some documentation before doing that though

I was hoping there was something like mymodel.Objects.filter(.....).output_sql()

Carolina: from django.db import connection

Carolina: print connection.queries

antonr, I read the turorial and many chapters of the book

db-api != faq

lookit that, right in the faq like I said :��

triton-mx: http://www.martin-geber.com/weblog/2007/10/29/d... here's something

antonr, thank you :)

np

Magus-, Uz_, Zalamander: I wrote up a better explanation (and what I'm using) at http://dpaste.com/38163/ .. have any ideas on how I could improve that or if my implementation is so borked that I should go hide under something old.
