Re: Best way to learn Django considering Python versions and etc.

[Russell Keith-Magee]

Two Scoops is a fantastic resource -- but it's not a tutorial. It's a
collection of best practices and useful patterns. It won't make a whole lot
of sense until you've got a handle on at least the basics of Django. If you
buy Two Scoops expecting a tutorial, you're going to be disappointed.

Yours,

Django and sessions race condition

[Martin F]

I have lost one day with struggling with django sessions and it seems that 
I am not really able to resolve it without coding my own sessions 
middleware or using some locking. The problem is, sessions are not stored 
even if the saving is triggered manually. It happens now and then, because 
of race condition which occurs when multiple simultaneous AJAX requests are 
sent from the client side. I'm using db backend. The thing is, everything 
is ok when calling only one start() dajaxice call from the javascript side.

So the question, why session is not stored sometimes? Should I lock the 
segment, where session is being stored? I double checked session_key is 
still the same. Should not be this resolved in the session middleware 
module?

Settings: SESSION_SAVE_EVERY_REQUEST = True

def print_session_keys(request, tmp):
session_key = request.session.session_key
session = Session.objects.get(session_key=session_key)
a = session.get_decoded()
print tmp+str(a.keys())
@dajaxice_registerdef start(request):
dajax = Dajax()

searchHash = os.urandom(16).encode('hex')

data = 1

print_session_keys(request, 'Before: - hash: '+searchHash+' ')
request.session.set_expiry(0)
request.session[searchHash] = data
request.session.modified = True
request.session.save()
print_session_keys(request, 'After: - hash: '+searchHash+' ')

*LOG:*

1 or 2 requestes of 3, are stored fine:

Before: - hash: 05f22e8e828a0e6145519e0bb0778357 
[u'b0d0d5e4ebe846c4e3ffa66bfbd2e7e3', u'usermode', u'_session_expiry']

Testing Frameworks and Practices(consensus?)

[Thomas Murphy]

Hi,

This seems like a more appropriate forum that SO for this discussion.

I've been testing my apps with Selenium, which seems to be a popular choice
for Django, but so does unittest and some others, as well as using coverage
to check for code coverage.

I'm curious to hear about others experience with testing frameworks,
particularly those who have moved through more than one about any best
practices experiences they've had, and what caused the choice to go with
what you're using now.

Best,
Thomas

formfield_for_foreignkey: kwargs is empty?

[Antony Seedhouse]

I'm trying to use formfield_for_foreignkey to filter the dropdown of a 
ModelAdmin with Django 1.6 on Python 2.7.6, following 
https://docs.djangoproject.com/en/1.6/ref/contrib/admin/

class CupAdmin(admin.ModelAdmin):
...

# hide inactive distributions
def formfield_for_foreignkey(self, db_field, request=None, **kwargs):
if db_field.name == 'distribution':
kwargs["queryset"] == Distribution.objects.exclude(active=False)
return super(CupAdmin, self).formfield_for_foreignkey(db_field, 
request, **kwargs)

My code fails because kwargs has no queryset, for both adding or editing

Django Version:1.6Exception Type:KeyErrorException Value:

'queryset'


When looking at localvars in the traceback, kwargs is empty ( {} )

Am I (or the docs) missing something?

Check "urls.py" file in your project manage folder.

A ModelForm operates on an instance of a model. Eg

instance = Quotation(filename='123')
form = QuotationForm(instance=instance)

ModelForms

[giuliano . bertoletti]

Hello,

when using ModelForms, which is the correct way to implement the "edit 
item" pattern?

Suppose I've a table with many rows, each representing a record in a 
database.
I choose one and wish to display/let the user edit the details.

I'm trying to use a ModelForm and fill some fields with specific data 
coming froma query.
The problem is I'm unable to initialize the fields and have the page served.

The arguments taken for a form do not work in a modelform.


class Quotation(models.Model):
#...
filename  = models.CharField("Filename", max_length=60)



#...

class QuotationForm(ModelForm):
class Meta:
model = Quotation

#...

def manage_quotations(request, quote_id):
# retrieve quotation here
# ...

# just try to fill a form and have the page served
qd = { 'filename' : '123' }

form = QuotationForm()   # cannot pass qd here as initializer
if request.method == "POST":
pass   # manage posted data

return render_to_response("quotes/manage_quotation.html", {
"form": form,
})

Re: Writing your first Django app, part 1 (1.6)

[Alasdair Nicol]

Hi,

The Django tutorial has changed between 1.6 and the current development 
version. Because your error references the Choices.question field, it 
sounds as if you may have been following the development version in places.


Make sure that you follow the Django 1.6 tutorial throughout. If you 
retry and follow the instructions, it should work.


You can select the version of the tutorial using the selector in the 
bottom-right corner of the screen.


Cheers,
Alasdair

When you encounter an error and ask for help, it is useful for those
helping you to see the error message. Here, you have purposefully
removed most of the error message.
