Re: request.method not working as expected

[Babatunde Akinyanmi]

Your post showed the trailing url...anyway I agree with your
diagnosis. With my noob knowledge of django, django tries to add a
trailing slash to your url when you don't. I believe she does that by
adding the trailing slash to the url and then asking the server to
redirect to the url which is the reason why the development server
logs show 301 status. However, when a 301 is gotten in response to a
request and the request method wasn't GET or HEAD, the client is
expected to ask the user before redirecting. If there is no automatic
addition of the trailing slash, the server will return a 500 instead
because django would be able to find the url in your given pattern and
raise an error.
My guess is that maybe django explicitly does the redirection by
sending a GET. I guess this is one of the times we need to check the
guts of django to understand her more.
However, if you believe you simply won't be able to cope with the
trailing slash, you could change your url pattern to exclude the
trailing slash though I don't know if that has side effects.that's
if you must absolutely hard code the url

How to solve MultiValueDictKeyError

[Kayode Odeyemi]

Hello friends,

I don't know why Django is so unstable.

Before restarting my computer everything works fine. Django could parse a
simple
POST request without complaining KeyError.

I'm simply making a POST request like this:

curl -v -H "Content-Type: application/json" -A 'Mozilla' -X POST --data
'fees={"fees":{"status":"pending","timeout":5},
"hostel":{"status":"pending","timeout": 3}}'
http://127.0.0.1:8000/api/transaction/add/ > post_data.txt

I also have it in valid dict format like this:

curl -v -H "Content-Type: application/json" -X POST --data
'fees={"fees":[("status","pending"),("timeout",5)],
"hostel":[("status","pending"),("timeout", 3)]'
http://127.0.0.1:8000/api/transaction/add/ > post_data.txt

This worked throughout yesterday. Just hoping to continue from where I left
off, and I can't progress as I would love to.

Trace:

The problem is simply understandable, but why didn't Django say this when I
worked on it yesterday. This is not fair Djanjo. It is not!

Somebody please help me.

Thats not x-www-form-urlencoded data, so expecting django to parse it
is not going to happen. Django parses x-www-form-urlencoded data.

It didn't work yesterday, you are mistaken. Django has never
automatically parsed json encoded post data, so if you think it did
yesterday, you are wrong.

I can swear it worked. I had the data in a queue and then processed.

In this case, the problem is a little bit different.
models.CharField.__init__ knows nothing about any 'baz' keyword
argument. With your current code, however, you keep the 'baz' item in
the kwargs dictionary and also pass this argument to
CharField.__init__. That's the cause of this error.

The remedy is simple, instead of kwargs.get use kwargs.pop.

Yes, you can run a script from within your view. Whether you *should* or not
depends largely on how long the script might take to run. While it's running
the Django instance serving the user's request and the user's browser will
hang waiting for it to complete, so if it's going to take a while then you'd
be better off running the script using something like Celery.

Re: Where does form.is_valid() clean the form?

[Jacob G]

Thanks all.

I figured out my mess-up: In the view, I instantiated the form incorrectly 
as follows:

form = AuthenticationForm(request.POST)

Instead of the correct way:

form = AuthenticationForm(request, data=request.POST)


The debugger weirdness distracted me from the real problem. I still don't 
know what happened with the debugger, but I've got other things to do, so 
I'm moving on...

Getting a count of a RawQuerySet object

[Jack]

Hello everyone, I'm quite new to django and python in general so I'm
sure there's just something I missed in my searching to answer this.
But...

Is there a way to count the number of results returned in the
RawQuerySet option?

I've tried the len() function and I've search the django documentation
with no results. So, any help would be very welcomed.

Thanks!

Re: changes to .py file is not reflected until server is restarted.

[Cal Leeming [Simplicity Media Ltd]]

Hi Vijay,

Some web app servers will allow you to 'touch' the wrapper file (wsgi.py for
example) which will in turn trigger a restart. Running manage.py in
'runserver' mode will also do this (this is for dev, NOT for production).

But for the most part, production will require you to restart the webapp
service in order to recognise changes (an exception being Apache, which
allows the 'touch' approach).

Hope this helps

Re: Getting a count of a RawQuerySet object

[Jack Morgan]

Hi, thanks!
The issue I'm getting here is that the RawQuerySet object does not have the
.count() method so it just gives an error.
I also just checked that it does not have the 'all()' method either.

Tom, the snarky tone is un-called-for and not OK. Cross-posting is

have known that. Please try to be nice when telling people about our
community standards.

And Kayode: I think you'll find you have a lot more luck getting your

bunch of volunteers. Calling Django "unstable" is a really bad way to
motivate the people who wrote it to try to help you out.

Sorry, I should have been more clear on this.

In your apache config, you should have specified a WSGI file to attach to
(assuming you are using WSGI) - this is the file you need to touch.

If not, please specify how you are telling Apache to connect to your python
app.

Customizing forms html

[Jacob G]

I'm trying to customize Django forms html based on three requirements:
1) Html output to match html given to me by a web site designer.
2) Automatically generate forms, so I don't have to duplicate html in 
templates.
3) Re-use as match of Django forms code as possible.

For my first attempt, I'm working on an authentication form. So here's what 
I did:
1) Derive AuthenticationForm class so that I can create use derived classes 
for the CharFields
2) Derive CharField to set css class in widget_attrs
3) Derived ErrorList to use own custom html for errors

Another problem came up: Django assumes that field errors should be 
displayed before the field label. However, I want to display the field error 
after the field's input (after a line break). It would seem that I would 
have to override BaseForm method _html_output, which I would like to avoid.

*Summary Question*: Is there a simpler way to output field error html after 
field, rather than before field, without having to override _html_output?

Thanks.

Comment Framework and Session Variables

[SixDegrees]

I'm using the Django-supplied comment framework, and I would like to
initialize the email field of the comment form with a value stored in a
session variable. The forms, however, are created using template tags; they
aren't instantiated in the view, for example, where I could easily provide
the session value as part of the 'initial' dictionary. I don't see any way
in the template to pass this value along so the form can make use of it. How
can I do this?

Firstly, mod_python is deprecated. Don't use it. Use mod_wsgi instead for 
production.

Secondly, for development, don't use Apache. Use the built-in runserver. 
That's what it's for.

You can also use get_success_url for that:

Re: Comment Framework and Session Variables

[Andres Reyes]

One possible way would be to create your own template tag and use it instead
of the provided one. I did it recently and it's not that complicated, you
should use the code for the current one as an starting point and just extend
it to accept some custom parameter you provide, in this case the email
field.

Django template IndexError

[Martin Tiršel]

Hello,

I have this situation:

class SomeClass(object):
...
def __getitem__(self, key):
...
raise IndexError()

and now:

context['somevar'] = {'one': 1, }
context['anothervar'] = SomeClass()


in template:

{{ somevar.one }} - prints 1
{{ somevar.two }} - prints nothing, no exception raised
{{ anothervar.notexistentindex }} - raises IndexError and page doesn't  
load (debug info printed)


Does anybody knows why? In both cases IndexError exception is raised but  
first case doesn't stop page loading, the another stops and prints debug  
info. I need silent ignore. What is the difference between "native"  
IndexError and my IndexError?



Thanks,
Martin

Re: Django template IndexError

[Martin Tiršel]

It seems, that Django handles methods and variables indexes differently.  
So I solved it this way:


e = IndexError()
e.silent_variable_failure = True
raise e

TransactionMiddleware recommendation

[Joseph Mou]

I saw that the docs recommend using TransactionMiddleware, even though it's
not the default:
https://docs.djangoproject.com/en/dev/topics/db/transactions/

Why is this preferable over the default auto-commit behavior? I wasn't able
to find much more information when searching (mostly just bug reports).

Thanks,
Joe

User Registration -> Password not saving

[Kurtis]

Hey,

I've created my own User Registration FormView. Everything seems to
work great except the password is always saved as "!". I can change
that with the "password changer" in the admin section of the site. I
am using an alternative authentication backend, so I'm not sure if
that was causing problems. I went ahead and included the default
authentication backend as well (at the front of the list) but that
didn't seem to change things. I've included my code at the bottom. Any
help would be greatly appreciated! Also, if there's anything wierd
about my code, let me know. I'm still learning.

class SignUpFormView(FormView):

template_name = u'base.html'
form_class = SignUpForm
success_url = '/pages/getting_started'

def form_valid(self, form):

# Gather Data
email = form.cleaned_data['email']
firstName = form.cleaned_data['firstName']
lastName = form.cleaned_data['lastName']
password = form.cleaned_data['password']

# Create a Unique UserName from a Hash
userName_hash = hashlib.md5(email).hexdigest()
userName_hash = userName_hash[:30]

# Create the User
user = User.objects.create_user(userName_hash, email,
password)
user.set_password(password) # Duplicated in hopes of it
working.
user.first_name = firstName
user.last_name = lastName
user.is_active = True

# Save the User
user.save()

return super(SignUpFormView, self).form_valid(form)

def form_invalid(self, form):
return super(SignUpFormView, self).form_invalid(form)

class SignUpForm(forms.Form):

email = forms.EmailField(required = True, label = u'Email
Address')
firstName = forms.CharField(required = True)
lastName = forms.CharField(required = True)
password = PasswordField()
password_confirm = forms.CharField(label = u'Password
Confirmation',
widget = forms.PasswordInput(render_value =
False),
required = True)

# Custom Form Validation
def clean(self):

cleaned_data = self.cleaned_data
password = cleaned_data.get('password')
password_confirm = cleaned_data.get('password_confirm')

# Check Password Matches Confirmation
if password and password_confirm:
if password is not password_confirm:
raise forms.ValidationError(u'Your passwords do not
match.')

return self.cleaned_data

If you are certain that every single time you modify the database, you want an 
immediate commit (no object graphics, no possibility of dangling objects), the 
default behavior might work for you.  However, as soon as you start having 
interdependent objects, you probably need something more sophisticated.

Yes - use a template.

Django's forms library includes some rendering capability, but that's
for scaffolding purposes. The intention is not to provide a completely
customizable way to generate HTML in code.

If Django's default form output doesn't meet your needs, then the
solution isn't to try and modify the code -- it's to modify the output
at the template level.

https://docs.djangoproject.com/en/1.3/topics/forms/#customizing-the-form-template

Is there any particular reason why it's assumed you won't be performing a Max on a CharField?

[Joshua Russo]

Is there any particular reason why it's assumed you won't be performing a 
Max on a CharField? 

I tried to create the following QuerySet:

Document.objects.filter(documentType=1, 
event__eventType=3).annotate(event_date=Max('event__start_date'), 
subcommittee=Max('event__subcommittee__name')).order_by('subcommittee', 
'event_date')

I enforce this particular documentType to occur only once per Event, but in 
reality the Document - Event relation is many to many. That is why I 
performed a Max on the to go from Document to a FK relation of Event.

I really only ask out of curiosity. As far as SQL goes, this is completely 
legit and I plan on modifying Django and submitting a patch. (Unless there's 
a compelling reason not to)
