zatan: ?

Nirvo: let's see if I remember from my hostgator setups...

Nirvo: did you chmod +x your .wsgi script?

yes

755

are you using a virtualenv?

Hi, how to set default `True` value for `forms.BooleanField` ?

no I dont.

Nirvo: ok... you have SSH acccess, yes?

yes

run the index.wsgi script from the shell

`forms.BooleanField` not have `default` option

OmidRaha: it has an initial option

OmidRaha: or you can pass intial to the form

OmidRaha: or set it in a custom __init__ method

FunkyBob: I want use it as a fallback

Funkybob: I see some HTML output. But there might be some errors at the begining since I cant see the whole output

Nirvo: pipe it through more, then

did you write a 404.html ?

no

you're probably going to want to :)

is this the first time you've tried to deploy?

yes

it is

are you uding Django 1.4 ?

using

their instructions are slightly wrong for 1.4

[and, interestingly, slightly wrong for <1.4 :), but in a different way]

Nirvo: hello?

yes

1.4

ok

well it says in top lines of output WSGIServer: missing FastCGI parm REQUEST method required

then change the sys.path.insert to insert the project dir

the one with manage.py in it

ok will try

nope still nothing

I get premature end of script headers .fcgi file in error log now.

and you did a pip install django flup ?

hmm

yes flup is installed

but it's not working?

how can I check?

hit the site

FunkyBob: i would like some advice

how much is it worth to ya?

I'll be back after dinner...

well, i don't know how much

i suppose it's worth my time asking you

FunkyBob: Thanks for the help man!!!!! It works now :)

back

Nirvo: cool

bradleyayers: ?

still waiting for you to ask

hi. model abstract class. What is difference between attributes in class which has meta subclass and attributes which are in that meta sublas?

so i've never done any performance tuning, other than using django-debug-toolbar to see how many queries are done, and to try and reduce it

ah

https://docs.djangoproject.com/en/dev/topics/db... what does ordering['name'] does in meta class?

and it's not really an issue since the stuff i do is low traffic internal business tools

but, what's the low hanging fruit that i would be worth me looking into

you seem to have an interest in such things

with your talk of template performance tests etc

ok

well, yo uknow select_related and prefetch_related

right, so other than reducing queries

in templates... avoid hitting the same query repeatedly... avoid excess inheritance... and {% include %}

how bad is include?

i was going to ask what the overhead of rendering a template is, e.g. Template('').render(Context())

but i realise i can just time it

:)

oh, also... use the caching template loader

does anyone know? :)

but really.. point NewRelic at it... it will show you soon enough

iwtu: show us code

iwtu: where is ordering['name'] ?

iwtu: your question is ambugious to me

ambiguous even

normally it's a list

FunkyBob: what about OS tuning

or database stuff?

do you do anything more than create index

yes

out-of-the-box, Postgres is usually poorly configured

especially for write-heavy loads

what is difference between attribues in abstract class and attribues in meta class within the abstract class

iwtu: one's on the class, one's in the meta class

iwtu: show us code

just show us code with both cases

iwtu: or tell us the problem you're really trying to solve

I showed you. I don't have any own code because I don't know when the attibutes should be on class and when on meta class

attribues on meta class has confused me

or the meta class is some special class with predefined attribues I can use?

FunkyBob: so do you just google around for postgres tuning guides

bradleyayers: there's a tuning tool... but just reading the pg docs is a good start

iwtu: exactly like with normal models... anything that goes on a Meta class ... goes on the meta class

oh. I see. All clear now :)

one more question. I am familiar with MVC but I missed Controller in Django. So.. the logic should be implement in view or model?

don

't

just ... don't

stop trying to force MVC concepts onto Django

there's a strong argument that _no_ web framework is, in fact, MVC...

i put business functions in reusable functions

app functions

then call them when necessary from views

iwtu: request comes in, is routed to a view function by the url patterns... view function returns a response.

done

reusable function in model and the other in view?

if it makes sense to wrap up some functionality as a method on the model, do that

the other are single use purpose

if it's more general purpose, i make a separate module and put it in that

for example creating emails to send

i have an emails.py, with functions to create different types of emails

remember that models don't have implicit access to the request...

the functions take information they require for the email, perhaps a model instance, and return a Django email object

ok. great guys :) I think I undestand somehow :)

in a view, if an email should be sent, i create one and send it

if you put everything in views, it becomes difficult to test

unit test, that is

iwtu: thank you for the question

bradleyayers: I'm serious about New Relic, btw... no way i'd do without now... even on the free account

i have new relic setup
