Please post your code for the model containing the "start_work" field. Must 
likely, you have defined the field with unique values and are now trying to 
create an model instance with a "start_work" foreign key reference that already 
exists.

Re: Django create userprofile

Ok, Thank you!

So, this is my the full codes;


class Staff(models.Model):
user = models.OneToOneField(User)
user_name = models.CharField(max_length=255,)
first_kana = models.CharField(max_length=255,)
last_kana  = models.CharField(max_length=255, )
employee_number = models.CharField(blank=True, max_length=22)
gender = models.CharField(max_length=6, choices=(('male', 
'男性'),('female', '女性')), verbose_name="性別" )
created_at = models.DateTimeField(auto_now_add=True,)
updated_at = models.DateTimeField(auto_now=True, )
birthday = models.DateField(null=True, blank=True, )


def __unicode__(self):
return self.user_name


class Myattendance(models.Model):
start_work = models.ForeignKey(Staff, verbose_name = "名前")
get_work_data = models.DateTimeField(default=datetime.now, verbose_name 
= "出勤時間")

class Meta:
ordering = ['-get_work_data']

def __unicode__(self):
return unicode(self.start_work)

class Myleavework(models.Model):
user = models.ForeignKey(Staff, verbose_name = "名前")
get_off_work_data = models.DateTimeField(default=datetime.now, 
verbose_name = "退勤時間")

class Meta:
ordering = ["-get_off_work_data"]

def __unicode__(self):
  return unicode(self.user)

This is my the views.py:

@login_required
def myattendance(request):
if request.POST:
   # attendance = get_object_or_404(Attendence, pk=user_id)
form = MyattendanceForm(request.POST)
if form.is_valid():
form.save()
return HttpResponse('Ok')
else:
form = MyattendanceForm()
args = {}
args.update(csrf(request))
args['form'] = form
return render_to_response('myattendance.html', args)

@login_required
def myleavework(request):
if request.POST:
#leavework = Leavework.objects.get(pk = request.user.id )
form = MyleaveworkForm(request.POST)
if form.is_valid():
form.save()
return HttpResponse('Ok')
else:
form = MyleaveworkForm()
args = {}
args.update(csrf(request))
args['form'] = form
return render_to_response('myleave.html', args)

This is my the forms.py:

class MyattendanceForm(forms.ModelForm):

class Meta:
model = Myattendance


class MyleaveworkForm(forms.ModelForm):

class Meta:
model = Myleavework

Are you sure your database is in sync with your model? The error message 
implies that the field is defined with unique=True, but your model doesn't 
define it so:

  start_work = models.ForeignKey(Staff, verbose_name = "名前")

PyDev 3.4.1 & Django 1.7: undefined variable from Import

2014-05-12 Thread Florian Auer

Hi folks

I'am new to django and try to follow the tutorial to digg into the code.

I am using eclipse 4.3.SR2 with PyDev 3.4.1 and Django 1.7.b2 (because of
the new features)
In Tutorial Part 3
(https://docs.djangoproject.com/en/1.7/intro/tutorial03/) the database API
is used to get the latest 5 objects

latest_question_list = Question.objects.order_by('-pub_date')[:5]

But my eclipse/PyDev does not resolve the objects correctly. "Question.
objects" will e resolved bot not further on. This leads to the problem that
PyDev is claiming about a "undefined variable from import: order_by"
I know that I can turn off this in the settings, but I would like to know
if there is a way to bring this auto-completion feature to work.

The application is running correctly an on the python shell the
auto-completion is also working.
So therefor I would think it is a PyDev problem or did I just missed to add
something to the config?

Re: django on rhel5 with both python2.4 and python2.7 confusion

2014-05-12 Thread David Malcolm

thanks for your reply WB.

I was hoping to avoid virtualenv. My webapp is a frontend to a vulnerability
scanner in a large corporation.
They are very picky about what I can use and what I can't. Is virtualenv
suitable for such a production system?
They insist that I cannot use mod_wsgi (it annoys me intensely, but hey that's
life) and HAVE to use mod_python.
Is there any other way to get this working without virtualenv?

I also have no choice about OS. rhel6 is undergoing an approval process as an
SOE but it won't happen any time soon :(

I am so close to getting this working now but it does indeed look like django
(httpd) is using python2.4.
Note that "which python" gives me 2.7 - what is causing django to use python &
mod_python 2.4? mod_python is installed for 2.7.

Mod_python error: "PythonHandler django.core.handlers.modpython"
Traceback (most recent call last):
File "/usr/lib64/python2.4/site-packages/mod_python/apache.py", line 287, in

thanks for your help.

Re: django on rhel5 with both python2.4 and python2.7 confusion

2014-05-12 Thread Timothy W. Cook

I can't imagine virtualenv being a vulnerability risk.  AFAIK; All it does
is create a set of scripts to isolate the executing Python environment.
http://virtualenv.readthedocs.org/en/latest/virtualenv.html

In fact, I would almost say that it improves your ability to know EXACTLY
what is in your environment irregardless of the rest of the machine.

Frankly, I do not create any Python code outside of a specified virtualenv.
 Web apps or any other scripts or apps.

But the code works, right?

This is a PyDev issue, not a Django issue.

(If you can only use code that your IDE understands, that leaves out a lot
of interesting programs.)

If I ever come across a production system where a python app is not
installed in a virtualenv, I consider that a bug. virtualenv is the
basis of all of our python production systems (our dev systems too).

mod_python is old, insecure, unmaintained, unmanaged - and most
importantly - not supported for django.

> Is there any other way to get this working without virtualenv?

Find the right person to talk to your in your org, tell them that
mod_python is dangerous, and that virtualenv is the industry standard
way of deploying a python application, and that wsgi is the industry
standard way of connecting a python web application to a web server.

+ means addition
= means assignment
+= means addition and assignment

Eg, a += 5 means a = a + 5

a += b

is nominally the same as

a = a + b

To make class instances support this behavior the class can implement the
__iadd__ special method.  See docs.python.org and read about special
methods.

This notation originated, so far as I know, in the C language.  It at least
goes back that far.

How to display the database table in administration tool??

2014-05-12 Thread dev tc

Hi,
I am really new to django (and python as well). 
I now try to create an app from the django. 
I want to view the database table on something like phpmyadmin, does django 
come with administration tool?
I installed the django on virtualenv on my local computer (Arch Linux), and 
it already have mariadb installed. How can I use it for my app on my local 
machine and finally use phpmyadmin to display the db and table? 
 

Thanks

Re: PyDev 3.4.1 & Django 1.7: undefined variable from Import

2014-05-12 Thread Bill Freeman

Also, I don't think that it's the += that he's worried about.  What he's
saying is that you shouldn't expect every sub-directory of BASE to always
be an app, and/or that the order of INSTALLED_APPS can be important, and/or
that your settings.py file should document what you are using.

Opinion needed for a BookMarker project - Regarding CSRF token

2014-05-12 Thread Aseem Bansal

I am new to Django and am learning it baically because I wanted to create a
BookMarker project. A project for managing bookmarks. For this I am going
to create a UI through Django and a JavaScript for sending the URLs to the
app. There is a problem of CSRF token in Django. I was able to do a dummy
POST request by sending the CSRF token hard-coded as a parameter. But I do
not understand how the CSRF tokens are generated. Can I just hard-code
them? I don't think that it should be possible otherwise there is no point
of having it in the first place. Should I consider turning off the CSRF
middleware as this is just local machine or should I keep it as a best
practice and find a way to generate the CSRF token in my JavaScript? That
would suck but I am out of opinions.

Also when you are doing Django projects and need to deal with JS then what
do you do? I mean is there an alternative for JS in Django?

If any of these questions doesn't make any sense please tell and I will try
to improve these. Just tell what doesn't make sense.

To use the csrf token and send it along with AJAX requests made in
javascript, refer
https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ajax .

It should be fairly straightforward following steps there. Let know if
anything is unclear or does not work.

Hope the documentation makes sense, otherwise just search for "django
ajax csrf token" or so and you should find quite a lot of examples
online :)

All the best.

Re: Opinion needed for a BookMarker project - Regarding CSRF token

2014-05-12 Thread Aseem Bansal

Hi Sanjay

I think you misunderstood a bit. The JS that I am talking about will not be 
inside the web pages of the project. The JS is supposed to be used as a 
Bookmarklet in the web browser. I intend to use the bookmarklet for sending 
the current webpage's url to the app via a POST request. The app will then 
store the URL.

Here a problem due to CSRF token would occur becuase I can hard-code the 
CSRF token in the JS for one environment but as I am not aware how the 
token is generated it would be difficult to dynamically generate the token 
in the JS for a different environment. For example if I tried to run the 
app on a different computer than I will have to manually check the CSRF 
token for that and change the hard-coding.

The entire purpose of CSRF is to stop things like that from being
possible. The bookmark makes a cross site request from the site you
are currently on to your django site.

In light of that, disable CSRF for that view.

I should also mention that this would also leave that view wide open
to a CSRF attack. A malicious user who can make you execute javascript
- if you view a webpage they either control, or have injected
javascript in to (like a forum) - could then make your browser make
forged requests to your view, submitting whatever content or url that
they wanted to it, using your credentials.

Generally people do their table joins in the database rather than the
template...

Could we start with what are you trying to achieve with this page,
rather than what is going wrong. What HTML should that section
generate?

Re: Django Template Based If Statement Issue

I'm just trying to associate each vm tied to the customers id and display 
the vms under the customer that are associated with his id.

Re: Django Template Based If Statement Issue

so as you can see when ever the vm field customer id matches the customers 
name i want to display the vm with the customer. To create a table of vms 
that each customer has. I also will be associating a third database with 
vmspecs to each vm.

I know there is an easier way to do this with django but i didn't quite 
understand waht the documentation was sayign

Normally, you would have some sort of relationship between those
models, and the template code would look something like this:

{% for customer in customers %}
{% for vms in customer.vms_set.all %}
{{ vms.id }} - {{ vms.NAME }} - {{ d.VMNAME }}

{% endfor %}
{% endfor %}

Please note, even if you are using a legacy database, there is no need
for the model's fields to have the same name as the table column. All
caps normally denotes a constant, these are not constants, and
"VMNAME" is less pleasant to look at than "virtual_machine_name" or
even "vm_name".

One other thing, your view, you should be actually calling the
function "all()", not passing the function object "all":

def index(request):
   customers = Customer.objects.all()
   ctx = { 'customers':customers }
   return render_to_response('index.html', ctx)

Note the brackets, and you no longer need to pass in 'vms' either, as
it should come from the relation.

If this doesn't work, please show your models.

Cheers

Tom

You have

{% for Vms in customer.vms_set_all %} 

And then 

{{ vms.id }}...

Vms is not the same variable as vms.

Django case, when, then on querysets

2014-05-12 Thread Anthony Hawkes

Hi Guys,

I need to replace results in a queryset and then perform counts and further 
queries on the set and have been trying to find a way of doing it.

Basically in some but not all cases I get a set of results eg select * from 
table and then I want to do a: case when column = 'some value' then 'some 
other value'.

Is there any way using django's queries or at least preserving the ability 
to continue using the queries using raw sql? (I've had a look at extra() 
but can't see a way to make it work)

Yes, but not "out of the box". I've responded on the SO thread; but the
short answer is that you need to override get_changeform_initial_data() in
your ModelAdmin class.

2. isn't it a bug if a user is able to generate a server error by messing

Not necessarily. It's only a bug if, when *using the APIs as documented*, a
user is able to generate a server error by providing faulty GET arguments.
Taking the extreme case of the argument - if you write a view that
knowingly does divide by zero, it's not a bug in Django that the user is
able to generate a 500 by visiting that view. In your case, the argument is
much more subtle, but you still have code that is "wrong", and as a result,
it's raising a 500.

Yours,
