Hi,
How can I fix number of concurrent sessions allowed at app level?
Basically I want a limit to how many concurrent requests to this url to keep the server from getting congested.
I guess some middleware hack?
Thanks.
In C# (within the context of T4 template see http://www.olegsych.com/2008/03/how-to-generate-multiple-outputs-from-single-t4-template/) I want to do this
<# String myTemplateVar;
#>
<# if (string.IsNullOrEmpty(myTemplateVar)) {
myTemplateVar= "name";
};
#>
I want to give a value to myTemplateVar if myTemplateVar has not already been setup by an external call from T4 engine in another template which would have this instruction:
CallContext.SetData("myTemplate.myTemplateVar", ExternalTemplateVar);
But I cannot even compile in C# why ? How to fix this ?
my form is
class MapForm(forms.ModelForm):
class Meta:
model = Map
fields = ('mapName', 'kmlStr')
and the view is :
map_form = MapForm(request.POST or None)
if map_form.is_valid():
map = map_form.save(commit=False)
map.mapName=map_form.mapName#is thie code right ?
how to get the mapName 's value , us 'map_form.mapName' ?
thanks
MYMESSAGE = "<div>Hello</div><p></p>Hello"
send_mail("testing",MYMESSAGE,"[email protected]",['[email protected]'],fail_silently=False)
However, this message doesn't get the HTML mime type when it is sent. In my outlook, I see the code...
I get the following error in the UDK Frontend when I try to make my project:
C:\UDK\UDK-2010-03\Development\Src\FixIt\Classes\ZInteraction.uc(58) : Error, Accessing a member of GameUISceneClient's within class through a context expression requires explicit 'Outer'
The class ZInteraction extends Interaction.
Line 58 is: GetSceneClient().ConsoleCommand("KEYNAME"@Key);
What is the problem here? I am still investigating and I will update as I find out more.
edit: Tried fixing the line up as class'UIRoot'.static.GetSceneClient().ConsoleCommand("KEYNAME"@Key); - no change.
For formatting a date using date filter you must use the following format :
{{ my_date|date:"Y-m-d" }}
If you use strftime from the standard datetime, you have to use the following :
my_date.strftime("%Y-%m-%d")
So my question is ... isn't it ugly (I guess it is because of the % that is used also for tags, and therefore is escaped or something) ?
But that's not the main question ... I would like to use the same DATE_FORMAT parametrized in settings.py all over the project, but it therefore seems that I cannot ! Is there a work around (for example a filter that removes the % after the date has been formatted like {{ my_date|date|dream_filter }}, because if I just use DATE_FORMAT = "%Y-%m-%d" I got something like %2001-%6-%12)?
Suppose I have my models set up already.
class books(models.Model):
title = models.CharField...
ISBN = models.Integer...
What if I want to add this column to my table?
user = models.ForeignKey(User, unique=True)
How would I write the raw SQL in my database so that this column works?
Hi,
I have an application to count the number of access to an object for each website in a same database.
class SimpleHit(models.Model):
"""
Hit is the hit counter of a given object
"""
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey('content_type', 'object_id')
site = models.ForeignKey(Site)
hits_total = models.PositiveIntegerField(default=0, blank=True)
[...]
class SimpleHitManager(models.Manager):
def get_query_set(self):
print self.model._meta.fields
qset = super(SimpleHitManager, self).get_query_set()
qset = qset.filter(hits__site=settings.SITE_ID)
return qset
class SimpleHitBase(models.Model):
hits = generic.GenericRelation(SimpleHit)
objects = SimpleHitManager()
_hits = None
def _db_get_hits(self, only=None):
if self._hits == None:
try:
self._hits = self.hits.get(site=settings.SITE_ID)
except SimpleHit.DoesNotExist:
self._hits = SimpleHit()
return self._hits
@property
def hits_total(self):
return self._db_get_hits().hits_total
[...]
class Meta:
abstract = True
And I have a model like:
class Model(SimpleHitBase):
name = models.CharField(max_length=255)
url = models.CharField(max_length=255)
rss = models.CharField(max_length=255)
creation = AutoNowAddDateTimeField()
update = AutoNowDateTimeField()
So, my problem is this one: when I call Model.objects.all(), I would like to have one request for the SQL (not two). In this case: one for Model in order to have information and one for the hits in order to have the counter (hits_total). This is because I cannot call directly hits.hits_total (due to SITE_ID?). I have tried select_related, but it seems to do not work...
Question:
- How can I add column automatically like (SELECT hits.hits_total, model.* FROM [...]) to the queryset?
- Or use a functional select_related with my models?
I want this model could be plugable on all other existing model.
Thank you,
Best regards.
Suppose this is my URL route:
(r'^test/?$','hello.life.views.test'),
How do I make it so that people can do .json, .xml, and it would pass a variable to my views.test, so that I know to make json or xml?
I am trying to set up Google App Engine unit testing for my web application. I downloaded the file from here.
I followed the instructions in the readmen by copying the directory gaeunit into the directory with the rest of my apps and registering 'gaeunit' in settings.py. This didn't seem sufficient to actually get things going. I also stuck url('^test(.*)', include('gaeunit.urls')) into my urls.py file.
When I go to the url http://localhost:8000/test, I get the following error:
[Errno 2] No such file or directory: '../../gaeunit/test'
Any suggestions? I'm not sure what I've done wrong. Thanks!
I have a script where it accepts a varying number of arguments.
I want to use func_get_args to perform operations on said arguments. If I have one function like this:
function Something() {
foreach(func_get_args($this) as $functions) {
// Do something
}
// Return..
}
I want to be able to call this function in, for example, another function to add/save entries. The add/save function would have arguments 'title', 'description' etc..
I basically want to know if there is a way to detect the context of a function call. Can I pass something to func_get_args that will let it know that its called in a certain function? So if I do:
function Save($title, $desc) {
$vars = $this->Something();
}
I want $vars to contain $title and $desc after modifying them.
I have this error:
'people' is an invalid keyword argument for this function
class Passage(models.Model):
name= models.CharField(max_length = 255)
who = models.ForeignKey(UserProfil)
class UserPassage(models.Model):
passage = models.ForeignKey(Passage)
people = models.ManyToManyField(UserProfil, null=True)
class UserProfil(models.Model):
user = models.OneToOneField(User)
name = models.CharField(max_length=50)
I try:
def join(request):
user = request.user
user_profil = UserProfil.objects.get(user=user)
passage = Passage.objects.get(id=2)
#line with error
up = UserPassage.objects.create(people= user_profil, passage=passage)
return render_to_response('thanks.html')
How to do correctly?
Thanks!
can somebody please explain my mistake, I have this class:
class Account{
private:
string strLastName;
string strFirstName;
int nID;
int nLines;
double lastBill;
public:
Account(string firstName, string lastName, int id);
friend string printAccount(string firstName, string lastName, int id, int lines, double lastBill);
}
but when I call it:
string reportAccounts() const {
string report(printAccountsHeader());
for(list<Account>::const_iterator i = listOfAccounts.begin(); i != listOfAccounts.end(); ++i){
report += printAccount(i->strFirstName, i->strLastName, i->nID, i->nLines, i->lastBill);;
}
return report;
}
I receive error within context, can somebody explain why? thanks in advance
I am trying to get a list of all existing model fields and properties for a given object. Is there a clean way to instrospect an object so that I can get a dict of fields and properties.
class MyModel(Model)
url = models.TextField()
def _get_location(self):
return "%s/jobs/%d"%(url, self.id)
location = property(_get_location)
What I want is something that returns a dict that looks like this:
{
'id' : 1,
'url':'http://foo',
'location' : 'http://foo/jobs/1'
}
I can use model._meta.fields to get the model fields, but this doesn't give me things that are properties but not real DB fields.
I'd like everything to function correctly, except when it's mobile, the entire site will used a set of specific templates.
Also, I'd like to autodetect if it's mobile. If so, then use that set of templates throughout the entire site.
I have a handful of users on a server. After updating the site, they don't see the new pages. Is there a way to globally force their browsers and providers to display the new page? Maybe from settings.py? I see there are decorators that look like they do this on a function level.
Sometimes the best way to debug something is to print some stuff to the page, and exit(), how can I do this in a Python/Django site?
e.g. in PHP:
echo $var;
exit();
Thanks
As far as I understand, the "Getting Started" guide of GAE with Python uses the webapp framework. However, it seems like it uses Django to render templates.
Does that mean that I can use the Django template engine without using its application framework?
