session management problem
Hi all,
In my application i have a login screen. The view is simple as below:
loginform=None
formvalid=True
if request.method == "POST":
username = request.POST['username']
password = request.POST['password']
loginform=LoginForm(request.POST)
formvalid=loginform.is_valid()
if formvalid:
user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
login(request, user)
return render_to_response("menu.html",
{"somekey":somevalue})
...
menu.html has some menus. One of them had the address of "localhost/add" which
is defined in urls.py also. The view for add, is also add. But at my add
function it seems i lost my session.
if not request.user.is_authenticated():
return HttpResponse("nok")
else:
return HttpResponse("ok")
So i am gettig alwasy nok on the screen. How can i keep accesing session values
from not posted sites?

javascript problem
Hi,
At my application i have ben working quiete fine but when i tested my app, i
saw that there is a problem about the function i am onlloading at the body
part.
So i have something as below:
This function is adding an onchange event to a form element (a select indeed).
When i select something from the drop box another select box is being updated.
The code is working on Firefox but when i tested with IE, i realized it is not
working.
I tried also by writing pure xmlHTTP requests and functions by thinking the
protoculous is not suitable with IE, but it it didn't work either.
So loadEventHandlers is never activating the update function defined in it. The
code is as below:
function updateDepartment(facultyname) {
if (facultyname!= '') {
new Ajax.Updater(
document.getElementById("{{ form.department.auto_id }}"),
'someurl/' + facultyname,
{method:'get'});
}
}
function loadEventHandlers() {
document.getElementById("{{ form.faculty.auto_id }}").onchange
=
function () {
updateDepartment(this.options[this.selectedIndex].value);
//test(this.options[this.selectedIndex].value);
// alert("ok");
};
}
So is there a restriction using onload functions at templates at Django?
Or should it normaly work but am i doing something wrong?

strange javascript problem at IE
Hi all,
I am having problems on executing the javascripts. At my django app, i added
this simple script to my base.html.
alert("ok");
I added these lines just after the body part by expecting to see an "ok" alert
message at the load of the first page of the application.
The code is working of Firefox but when i tested with IE, i dont see any
messages. I didn't find a solution yet. Anybody encounter with the same issue
before?

matplotlib usage problem
Hi, I was trying to use the matplotlib at my Django view. The version i was trying is 0.98. What i did is to import the library and then plot a graph. The problem is when i tried the "from pylab import *", i got "RuntimeError: could not create GdkCursor object". This is most probably because of the apache user is not able to access the X server. Indeed at my distro it doesn't have shell account. I don't want to define X access to apache user. So what do you suggest? -- Oguz Yarimtepe --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

filling model choices field according to language code
Hi,
In my django application i have a Ticket class at my model as below
class Ticket(models.Model):
...
faculty = models.SmallIntegerField(
_('Faculty'),
#edit begins
choices=((0,""),),
#edit begins
default=0,
blank=False,
null=True,
help_text=_('Faculty name of the ticket related with'),
)
The thing is, i want to fill the choices part dynamically. According to the
language, i want to fill the string part so at the template the right human
readable string will be seen. Because i couldn't visualize how i can do it, i
tried to fix it at the view part as
if lang == "en":
form.fields['faculty'].choices = [(0, '')] +
[[f.fakulte_id, f.faculty_name] for f in Faculty.objects.all()]
fak=Faculty.objects.get(fakulte_id=fak)
form.fields['department'].choices = [(0, '')] +
[[d.bolum_id, d.dep_name] for d in fak.department_set.all()]
if lang == "tr":
form.fields['faculty'].choices = [(0, '')] +
[[f.fakulte_id, f.fakulte_tr] for f in Faculty.objects.all()]
fak=Faculty.objects.get(fakulte_id=fak)
form.fields['department'].choices = [(0, '')] +
[[d.bolum_id, d.bolum_tr] for d in fak.department_set.all()]
form.fields['problemcategory'].choices = [(0, '')] + [[p.id,
p.category] for p in ProblemCategory.objects.all()]
As you can see i have problemcategory and department fields also. At the ticket
edit issue, i have modelform as
class EditTicketForm(forms.ModelForm):
class Meta:
model = Ticket
And at the view
form = EditTicketForm(request.POST, instance=ticket)
lang=request.LANGUAGE_CODE
fak=int(request.POST["faculty"])
The rest continues as above lang part. When i tried
if form.is_valid():
i got errors saying that the values from the department, faculty and
problemcategory fields are not valid. When i add a clean method for modelform as
def clean_faculty(self):
data = self.cleaned_data['faculty']
return 0
the error related with faculty is gone. So it seems modelform is creating the
choices with (0, "") which is defined at the model. How can i fix it like at
the view part so that i will fill the choices according to the language code?

ajax toolkit suggest request
Hi, I need some ajax help at my Django application. I haven't used ajax before so it will be good if someone suggest me some toolkits so that i won't spend time reading all ajax things. One thing that i want to do is filling a text box by clicking a button. It will be good if another Django form site is opened and after choosing the required value (most probably by clicking a check box) and submiting , i want to see the selected value at the text area. Maybe this is not a related topic with ajax, but i dont know how i will do it in Django. It may be a javascript job, i dont know. Second, i want to update some form parts or part of the site when a form elements value is changed. Any help will be helpful.

Django web app reaching rest api and CORS problem
I have a django app and at the template part i have javascript function
calling the rest api:
http://komandor.app.gittigidiyor.net:8000/static/js/select-autofiller.js>">
At the js file i am filling a select box according to the returned json
response
$('#field1').change(function(){
var var1=$("#filed2").val();
var var2=$("#field1 option:selected").text();
url="http://www.foo.com:8080/"; + var1 + "/" + var2 + "/";
$.get(url, function( data ) {
alert( "Load was performed." + data);
});
});
The Django web app is running on www.foo.com:8000
At the rest api side, falcon is running and i installed falcon-cors
import falcon
from wsgiref import simple_server
from falcon_cors import CORS
check_python()
cors = CORS(allow_origins_list=settings.ALLOWED_ORIGINS)
api = falcon.API(
media_type='application/json',
middleware=[
# json.RequireJSON(),
# json.JSONTranslator(),
https.RequireHTTPS(),
headers.BaseHeaders(),
handle_404.WrongURL(),
cors.middleware
],
)
***
route definitions
httpd = simple_server.make_server('0.0.0.0', 8080, api)
httpd.serve_forever()
ALLOWED_ORIGINS is a list: ['www.foo.com:8000', 'www.foo.com:8080']
Still when i select the box and triggered the js at the Django web app, i am
getting
XMLHttpRequest cannot load http://www.foo.com:8080/var1/var2. Response to
preflight request doesn't pass access control check:
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'http://www.foo.com:8000' is therefore not allowed access. The response
had HTTP status code 400.
I couldn't find ow to fix it.
Any idea?
