Re: __init__.py file executed twice ?

2010-12-15 Thread mart 
Yes it seems usual referring to the blog post. So if the serveur
restart, that's not a problem that the init are executed several times...

With the mod_wsgi and apache where can I see the results of my "print" ?

Update user page after thread execution

2010-12-15 Thread mart 
Hello,

In my architecture, I send messages to a port object (implemented as a
queue in a thread). I'm giving callback function with the result of the
call.

For example, after filling the registration form,

# views.py
...
def createprofile(request):
...
gui_port.send_to(port_profile,('recordprofile',[arg1, arg2,..],
callback,
request))
return render_to_response('wait.html', locals())

def callback(request, status):
if status:
return render_to_response('success.html', locals())
else:
return render_to_response('fail.html', locals())


# profilemanager.py (the port object related to profiles)
...
# when received the message
try:
# some operations, update db,...
except:
# callback function with status = False
threading.Thread(target = msg[2], args = (msg[3],False)).start()
else:
# callback function with status = False
threading.Thread(target = msg[2], args = (msg[3],True)).start()


The problem is that (as expected) the callback function doesn't change
the user webpage when it happens.

Is there a way to do it (using AJAX maybe)

Thank you

Send email : from_email ignored

2010-12-14 Thread mart 
Hi,

I'd like to send an email from django. This is the code I'm using :

# views.py
def hello(request):
send_mail('subject', "body", "anot...@email.com", ["d...@gmail.com"])
return render_to_response('hello.html', locals())

# settings.py
EMAIL_USE_TLS = True
EMAIL_HOST = "smtp.gmail.com"
EMAIL_HOST_USER = "myem...@gmail.com"
EMAIL_HOST_PASSWORD = "mypassword"
EMAIL_PORT = 587
DEFAULT_FROM_EMAIL = "notexi...@email.com"

The email is correctly send to d...@gmail.com but there is no mention of
anot...@email.com. The email is received as coming from
myem...@gmail.com. I was expecting that it would be anot...@email.com
(or at least a mention of it).

Thank you

mart

thanks thomas,

i am aware of that, it is more the basic layout principle of such a  
"cart"
the fixed price (and discount or such) of day1 would go into the  
ordered_products "through" table
if its gonna be a many-to-many-field in "orders"

thanks for your fast reply!

My question is more if that is considered to be best practice?

I am sure many others do have similar scenarios here and there.
do you set it up the same way?

are there any caveats to use many-to-many relations?

things like putting more than one many-to-many field in e.g.
"order":

>   class Product(Model):
> pass # your code here
  class Job(Model)

>   class Order(Model):
> products = ManyToMany("Product", through="ProductOrdered")

jobstodo = ManyToMany("Jobs",through="JobsToDo")
