I can manipulate the Python code on its own, but I don't understand the steps between having the Python code in order and actually implementing it on a site. I can't seem to find any helpful tutorials. Everything I find seems to assume that the user knows how to complete this final step. Does this have to be done via Django? Can anyone point me to a tutorial? Thanks in advance. CND </pre> C. N.

Anyways, I have a large set of calculations in my models. I'm trying to stick with the OOP style for future maintainers or whomever else has to work with the code. The problem is that I'm up to 100 queries on a single view. Many of these queries are duplicated. Others are very close to being duplicated except for the 'comparison key'. (e.g. where user = foo) I'm hoping there is some sort of mechanism out there to easily cache these DB calls on a per-query basis. The calculations themselves are incredibly intensive (relatively speaking) but 100 queries per view can easily turn into a nightmare if this project becomes popular. Is there any "out of the box" solutions to caching Query Sets within the scope of a single request? I am using a combination of class methods, instance methods, and in some places simple generic methods so I'm really pursuing a way to cache these at a lower level. These should only be cached for the duration of the request. I've seen some 'hackish' options and of course there are the larger ORM caching libraries but I'd like to find a clean solution without a whole lot of overhead. Thanks! - Kurtis </pre> Kurtis 2013-06-19T23:33:38 http://comments.gmane.org/gmane.comp.python.django.user/154552 <pre>I'm trying to use ffmpeg to generate a thumbnail for a video. It works just fine when I call it from a python shell and when I test it in "python manage.py shell". However when I try to run from the apache server running locally, I get an error: # normally I call subprocess.call, but for debug here I'm calling check_call response = subprocess.check_call(['ffmpeg', '-i', self.file.path], stderr=fh) # actual path taken out for brevity Command '['ffmpeg', '-i', u'...']' returned non-zero exit status -6 I've verified that the video path is correct. Any suggestions? Thanks!

In my database, I have some information stored around external data, represented by this kind of model : LiveInfo(models.Model): external_id = models.IntegerField() live_url = models.URLField() description = models.TextField() (I receive data from an external API, and I store the above information around it, external_id refers to the external element) Not all external elements have local information associated, depending of the needs for a "live" or not. What I need to do is, from a list of external ids, to construct a set of forms representing the data I may have around them. For exemple, from the external ids [12, 20, 48, 50, 55, 58, ], I need to construct a set of forms for each element, filled with the local LiveInfo data if present, empty forms for the others. The problem is that I need them in the exact order that I receive the ids. This means that my formset will alternate empty and filled forms. On global save, of course, I update the already present LiveInfo, and create new ones for the others. But I can't find any way to do this properly with formsets. Maybe it's simply not possible, and I have to construct my own set of individual forms, an manage my own global validation. I don't know if I'm clear enough, hope so. Any idea please ? :D </pre> Freddy 2013-06-19T20:38:59 http://comments.gmane.org/gmane.comp.python.django.user/154545 <pre>how generate xml or dme file django I want the result be like this : &lt;abc:ISA95_Company rdf:ID="Alaaadnan"&gt; &lt;abc:ABC_IdentifiedObject.name&gt;asfa Adnan Company&lt;/abc:ABC_IdentifiedObject.name&gt; &lt;abc:ABC_UnnamedObject.alias&gt;asfa Adnan&lt;/abc:ABC_UnnamedObject.alias&gt; &lt;abc:ABC_UnnamedObject.description&gt;Company Model for asfa Adnan&lt;/abc:ABC_UnnamedObject.description&gt; &lt;abc:ABC_UnnamedObject.mrid&gt;Alaaadnan&lt;/abc:ABC_UnnamedObject.mrid&gt; &lt;abc:ABC_OrganizationalEntity.TypeOfOrganizationalEntity&gt;Company&lt;/abc:ABC_OrganizationalEntity.TypeOfOrganizationalEntity&gt; &lt;/abc:ISA95_Company&gt; </pre> cha 2013-06-19T20:09:45 http://comments.gmane.org/gmane.comp.python.django.user/154544 <pre>Hi everyone I just started learning django. Question arises in my mind to write a script, by using that script i wanted to jump django version 1.5.1 without effecting my previous settings or effecting my application which is currently running on django 1.4.3.

I am getting executing my view.py and most of the modules it uses. But in one scenario, the import fails, see directory outline below NewMdsServer |___NewMdsServer |___settings.py |___wsgi.py |___ ... |___app |___views.py |___mymodule.py |___mypackage |___ __init__.py |___ x.py |___ y.py I have code in the __init__.py which then imports x, y, etc I cannot seem to import mypackage from views or other modules at the same level. I've tried multiple variants as shown below and sys.path includes the directory above app. from app import mypackage -- "No module named mypackage" import mypackage -- "No module named .. import app.mypackage -- ditto The really strange thing is I could swear this was working last week before I got pulled off onto another project for a few days.

We are still looking for talks and tutorials; first-time presenters particularly encouraged to participate! The URL is: http://www.djangocon.us/cfp/ (The site is being updated shortly, but if it still says 6/18, don't worry.)

But what about the action (method call) of sending the email? what layer should be responsible for triggering an email notification? models or views? This is something I keep wondering myself for a long time ... for example, imagine we have a simple Ticket model with two methods, update() and notify_owner() class Ticket(models.Model): def update(self): self.updated_on = now() self.save() def notify_owner(self, msg): send_mail(self.owner, msg) now we want to notify the owner each time a Ticket is updated, shall we include a self.notify_owner('updated!') call on the update() method, so we make sure of that? or maybe it is better to do this on the view each time ticket.update() is called? There are some pros and cons, In the views we have access to the request object which some times is handy because we need some request info to include on the mail. Including the call into the model we make sure that each time we will send an email notification and DRY is good, but is this behavior correct? maybe we only want to notify under certain circumstances... So anyone has thought about this? any rule of thumb? maybe it totally depends on the use case? does this question even make sense? :) Thanks for your answers! </pre> Marc Aymerich 2013-06-19T18:12:33 http://comments.gmane.org/gmane.comp.python.django.user/154536 <pre>Hi !, I am working on django cms based website. Where I used django form designer( https://github.com/samluescher/django-form-designer) Now I want to integrate djago-recaptcha with django form designer to add captch field in form. In django-form-designer settings.py FIELD_CLASSES = getattr(settings, 'FORM_DESIGNER_FIELD_CLASSES', ( ('django.forms.CharField', _('Text')), ('django.forms.EmailField', _('E-mail address')), ('django.forms.URLField', _('Web address')), ('django.forms.IntegerField', _('Number')), ('django.forms.DecimalField', _('Decimal number')), ('django.forms.BooleanField', _('Yes/No')), ('django.forms.DateField', _('Date')), ('django.forms.DateTimeField', _('Date &amp; time')), ('django.forms.TimeField', _('Time')), ('django.forms.ChoiceField', _('Choice')), ('django.forms.MultipleChoiceField', _('Multiple Choice')), ('django.forms.ModelChoiceField', _('Model Choice')), ('django.forms.ModelMultipleChoiceField', _('Model Multiple Choice')), ('django.forms.RegexField', _('Regex')), ('django.forms.FileField', _('File')), # ('captcha.fields.CaptchaField', _('Captcha')), )) Captcha field is commented, so I tried to override the settings in my project's settings. Then I get error "CaptchaField does not exist". What should I do ? And another doubt is how to send html email after successful submission of form. Any pointer or help would be great. Thanks </pre> pradnya 2013-06-19T17:31:08 http://comments.gmane.org/gmane.comp.python.django.user/154533 <pre>So I have been looking at different examples using multi-object forms where you bring in objects of different classes. I also looked at formsets but I don't think these fit what I want to do. class Alarm(models.Model): location = models.ForeignKey(Location, related_name='alarms') owners = models.ManyToManyField(User, related_name='users') #active = models.NullBooleanField(default=True, blank=True, null=True) trigger = models.CharField(max_length=25, blank=False, null=True) critical_low = models.DecimalField(max_digits=10, decimal_places=3) critical_high = models.DecimalField(max_digits=10, decimal_places=3) I want to present the user with a form that allows the user to select multiple locations without storing the locations in the one record (avoid using many to many relationship). I want it to create as many alarm records as there is locations selected. So if location 1 &amp; 2 is selected, 2 alarm objects will be crated/saved with the exact same data for owners, trigger and low/high fields. I'm relatively new to Django and don't know how to approach this. </pre> Radomir Wojcik 2013-06-19T16:46:26 http://comments.gmane.org/gmane.comp.python.django.user/154531 <pre>Hi!

I recently had our admin open up a port in our firewall to deploy another app publicly. We weren't using the app and there were issues when testing, since both the admin and myself are newbies to deploying publicly with Apache with SSL. So we left the server as is and tested UX for this app on an external host. We installed a new system wide firewall last week which the admin thought would help with our issues so I went to do some server prep today to bring the app on an internal server again. A check of the access logs found a specific external IP address hitting the server every 1/4 second with strange URLs that look to be commonly used php urls since June 7,2013. It has been getting hit for DAYs and I just wasn't monitoring the server. Each of the requests either 302'd or 404'd and there are thousands of them. I stopped the server, and sent an email to the admin to close that port down. Since neither I nor the system admin know much about deploying, is there anywhere I can look to hire someone to help get this app deployed safely? Our policies require SSL and we are willing to use other OS or servers, we just need someone who knows what they are doing. We are in the NYC vicinity.
