Re: Looking for a way to broadcast live video streams. Is it possible with Django ?

[Jeremy Hermelin]

Thank you Russ and Cal for your answers. 

I'll take a look at WebRTC that seems to be a revolution in that domain, 
and it's a matter of time before it will spread to Safari or IE.

You can not do it directly. This should be do by JavaScript's using at HTML
side. All field s are added to form and some of them are hidden.

Best practice to render the view based on the user

[Karim]

Hi! I would like to render views based on the user. I have some differents
type of users on my app and I would like to create a class like this one
for the view:

class MyView(MyCustomView)  # MyCustomView subclass View

def __init__(self, *args, **kwargs):
# common code for all persons

def personA(self):
# code for personA

def personB(self):
# code for personA

# 

def personN(self):
# code for personA

def anyPerson(self)
# For any user non listed above


Then if the MyView is run, the function based on the user is automatically
fired.

My doubts (at the moment):

1) Do you think is the a good way to face the problem?

2) I have methods in the models to know what person is logged. How I can
automatically load the right function in the class based on the user?

Thank you

Re: Help in Django-contact-form

[Vijay Khemlani]

And I'm not following, contact_form does not provide a ContactForm model,
but you are providing one it seems, but it's on the same contact_form
package as the library itself?

Also, the fact that the model class has the same name as the form class
does not help much.

Re: Django UnicodeDecodeError at /admin/login/

[Human Bsd]

Hi James. your hint  was actually very inspiring.

After concatenating  'drupal$' to the imported password, I was still unable
to authenticate. Then I realized that the passwords are in unicode but the
hasher considers them to be ascii, so I added :

password = password.encode('ascii','ignore')

at the begining of the both 'encode' and 'verify' methods

This solved the problem and saved my escape rout out of drupal :)

Thank you very much for your hint.

Re: Looking for a way to broadcast live video streams. Is it possible with Django ?

[Cal Leeming]

This really isn't something Django can do out of the box, but if
you're looking to get simple video streams integrated into your site,
then perhaps consider using LiveStream embed instead?

If you're looking to create your own service, then unless you are a
skilled programmer with experience in multiple languages/frameworks
then you're gonna find this extremely difficult, as you have a ton of
other components which would need to be included and a variety of
technical challenges to overcome.

Previously I worked on a similar project which used Flash fallback for
encoding when WebRTC wasn't available, there are all sorts of weird
edge cases due to browser bugs, including 100% CPU bugs when encoding
streams above 720p in Chrome (which has been outstanding for 2 years).
For flash fallback, you also have to implement IPC between Flash and
JS because you would only want to offload rendering and RTMP to flash,
not the entire interface. I might consider open sourcing this part of
the code if there is interest for it.

Then you have to consider the backend, handling video streams is an
absolute pita and most streaming solutions have poor performance or
leak memory. There are some out of the box streaming servers such as
Wowza, or the awful FMS (stay away from this, seriously), then you
also have to consider bandwidth usage, distributing load, handling
spikes, preventing DoS, mitigating DDoS.. You could look at using
Zencoder live transcode but this isn't cheap by any means (and for
good reason).

If you're looking for a fantastic learning experience, then try
building your own. If you're looking to just get something working,
use LiveStream embed :)

Hope this helps

Cal

Re: Looking for a way to broadcast live video streams. Is it possible with Django ?

[Russell Keith-Magee]

Hi Jeremy,

What you're trying to tackle here is fairly complex - and for the most
part, won't have anything to do with Django. The capability of capturing
webcam video and sending it will be almost entirely "client side" - which
means that the logic will reside in the browser, and will be implemented in
Javascript.

The only involvement Django will have will be:
1) Sending the initial content to the user
2) Receiving video content, if it's going to be archived.

If you're looking to do Hangout-like stuff, you're going to be using the
WebRTC extensions that are available in *some* browsers - the best
resources I can point you at are:

http://www.webrtc.org
http://simplewebrtc.com

But even then - the specification isn't widespread. Safari, for example,
doesn't support WebRTC, and neither does IE. That doesn't mean you can't do
hangout in Safari or IE - clearly you can - but it means the interface
isn't going to be easy, either.

Yours,
Russ Magee %-)

 It may, by coincidence, in your current environment behave that way.
 But change databases, or add more rows, or look at it funny, and that
 won't be true.

Re: forloop

Hi James,
Thanks very much for shearing your intellect, i really appreciate your
help. It works perfectly well. i want the users who receive the email to be
able to know who have apply for the leave: where it is highlighted blue i
want to put like test user have apply for a leave. could you please advise
how to do that.
here is my view.py

def email_authorizer(request):
email_obj = newleave.objects.order_by('-pk')[0]
if email_obj.department == 'GOV':
to_emails = [u.email for u in
User.objects.filter(username__in=['sabiut'])]
send_mail("RBV Leave Application Email Testing", "You have received
a leave application form. Please login to the leave system to Authorize the
leave. \nPlease ignore this message, we are testing the new eLeave system!",
"RBV eLeave ", [to_emails])
return render_to_response('thankyou.html')

Help in Django-contact-form

[Akash Nimare]

Hello everyone. I am using a third party app django-contact-form. It is 
working fine but the problem is it does not show my models in admin. I 
can't see the data in admin. The docs are very poor.
Here is my model.py 

from django.db import models
from contact_form.forms import ContactForm
class ContactForm(models.Model):
name = models.CharField(max_length=100)
email = models.EmailField(max_length=200)
body = models.CharField(max_length=200)
def __str__(self):
return (self.email)

 admin.py
from django.contrib import admin
from . import models
from contact_form.models import ContactForm
class ContactFormAdmin(admin.ModelAdmin):
list_display = ("name", "body", "email")
admin.site.register(ContactForm, ContactFormAdmin)
I am using django 1.7
http://django-contact-form.readthedocs.org/en/latest/quickstart.html

Re: Wanted: Best practices for setting "_" (to ugettext/ugettext_lazy)

[Collin Anderson]

Hi,

Why reset it at the end of your module?

Why not use ugettext_lazy everywhere?
from django.utils.translation import ugettext_lazy as _

(Disclaimer: I've never used translations before :)

Re: Forms test run on development database instead of test database

[Collin Anderson]

Hi,

I just tried out your project. Looking at the stacktrace, the test module 
is importing forms (before the test starts). The forms module is running a 
query on startup for choices.

https://github.com/merwan/django-choicefield/blob/master/myapp/forms.py

Don't do queries on startup. :)

 Hi,

 Yes, this is possible. Something like:

 from django.core.mail import send_mail

 def authorized_leave(request):
 form = MyForm()
 if request.method == 'POST':
 form = MyForm(request.POST)
 if form.is_valid():
 obj = form.save()
 send_mail('Subject here', 'Here is the message.', '
 fr...@example.com', ['t...@example.com'])
 return redirect('/done/')
 return render(request, 'template.html', {form: 'form'})

Hi,

What database are you using?

If you can reproduce this in a simple project, feel free to open a ticket 
about it.

I would not recommend godaddy.com, they try really hard to upsell you, I use

Re: Django: How to customize the admin form for specific model

[Collin Anderson]

Hi,

You could have the images be inline:

class CommentImageInline(models.TabularInline):
model = CommentImage
extra = 0

class CommentAdmin(models.ModelAdmin):
inlines = [CommentImageInline]

Though, you may need to use a custom widget to get the actual images to 
show up.

Re: Dictionary in admin interface

Hi,

The admin doesn't really have a way to do this. You could edit KeyValuePair

Why not have a "Params" model that has a ForeignKey to Request?

Re: Django UnicodeDecodeError at /admin/login/

Did you read the comments on that snippet? It appears there may need to be
some extra encoding/decoding needed (example additional code is listed
there), which would make sense given the decoding errors you are seeing.

Re: How to detect (daily) User Login when using cookies?

[Collin Anderson]

Hi,

Would it make sense to simply keep a record of when the last time you've 
seen the user is?

Django UnicodeDecodeError at /admin/login/

[Supermario]

I try to implement this  hasher 
in order to be able to authenticate user who are imported from drupal 7. 

So I put the hasher in the settings.py as follows:


PASSWORD_HASHERS = (

'myproj.drupal_hasher.DrupalPasswordHasher', #drupal hasher
 
'django.contrib.auth.hashers.PBKDF2SHA1PasswordHasher',

'django.contrib.auth.hashers.BCryptPasswordHasher',
'django.contrib.auth.hashers.SHA1PasswordHasher',
'django.contrib.auth.hashers.MD5PasswordHasher',
'django.contrib.auth.hashers.CryptPasswordHasher',
 ) 



However it does not authenticate imported users from drupal and for users 
who are created in Django I get:

'ascii' codec can't decode byte 0xcf in position 0: ordinal not in 
range(128)

django / tastypie - how to exclude a resource attribute from obj_create, but keep it for listing

[Eugene Goldberg]

  I have the following tastypie resource:

 class WorkloadResource(ModelResource):
# blueprints = ManyToManyField(Blueprint, 'blueprints')
blueprint = fields.OneToManyField('catalog.api.BlueprintResource', 
attribute='blueprint',
 related_name='workloads', full=True, 
null=True)

def obj_create(self, bundle, request=None, **kwargs):
# return super(WorkloadResource, self).obj_create(bundle, request, 
**kwargs)
return super(WorkloadResource, self).obj_create(bundle, 
request=request, **kwargs)

def obj_update(self, bundle, request=None, **kwargs):

workload = Workload.objects.get(id=kwargs.get("pk"))
workload.description = bundle.data.get("description")
workload.name = bundle.data.get("name")
workload.image = bundle.data.get("image")
workload.flavor = bundle.data.get("flavor")
workload.save()

def obj_delete(self, bundle, **kwargs):

return super(WorkloadResource, self).obj_delete(bundle)

def determine_format(self, request):
return 'application/json'

class Meta:
queryset = Workload.objects.all()
resource_name = 'workload'
authorization=Authorization()
filtering = {
"blueprint": ('exact', ),
}


 When I use curl to POST: 

 curl -i -H "Content-Type: application/json" -X POST -d 
 @wkl.json  http://localhost:8000/api/workload/

 where wkl.json is:

 { "name":"w 5", "description":"w 5 desc" }


 I get this error:

 AttributeError: 'Workload' object has no attribute 'blueprint'

 I do need to have this attribute, so I can list all child workloads for a 
given blueprint 
 like this:  GET /api/workload/?blueprint=1

 but I need to exclude this 'blueprint' attribute from participating in the 
obj_create

 What is the proper place and syntax to do this?


-Eugene

Re: django doubt

[George Silva]

Virtualenv helps you isolate between environments. Imagine that you work
where you need to develop and maintain two applications.

One is written in Django.1.5 and the other one on Django 1.7.

How do you install two versions of Django inside your system python
environment? You can't. That's what virtualenv does, it allows you to
create multiple environments, each with it's own libraries.

If you don't use virtualenv, you will have a hard time maintain multiple
applications with the same development box.

Virtualenvwrapper is just a wrapper on top of virtualenv, allowing you to
type easier commands to create, remove, list virtual envs.

Looking for a way to broadcast live video streams. Is it possible with Django ?

[Jeremy Hermelin]

Hi everybody, 

I'm quite new in Django community. I've just learn the basics of the 
framework, and now that I know how to create a "blog-style" website, I'm 
wondering how to integrate video streams in my project. Do you have some 
advices about that ? Any existing app ? 

What I am looking for precisely : 
- Capturing video stream from a client's webcam (Maybe the easier will be 
using a script)
- Sending the stream to the server and then to hundreds of clients 
connected to this session. 

In fact, it's really close to Google Hangout. 

As I said, I'm new in Django, and also in Python, then I'm sorry if the 
answer is obvious. I've made some research on djangopackages but haven't 
find anything. 


Have an awesome and fantastic day, 

Jeremy

By the way : Wooohhh Django is so easy and powerful at the same time !

not need the SEO boost or slight performance boost (known as time to first 
tweet problem, see 
https://blog.twitter.com/2012/improving-performance-on-twittercom ) , there 
is no need for this integration.

 Hi Bob,

 This is definitely not the only way but I don't  think it adds that 
 much complexity considering the advantages. You could have multiple 
 node.js 
 renderers, gain fault tolerance and performance via some distribution 
 scheme like round-robin.  The nodejs renderer here is stateless and could 
 be made even faster through memoization or caching (or cache could be 
 handled on python side too before communicating with node)

 Another alternative would be to use something like queues to handle 
 communication between node and django, but that is more complex. 

 The other alternative would be to fork a nodejs process on each call, 
 for a high traffic site, speed might be more of an issue there. Some 
 projects take that approach, I recently saw another django-react 
 integration that uses that. (See django-node for this)

 If you are on jvm, it is possible to use nashorn to do in process 
 rendering. 

 Best,

 Üstün

Re: read GET and POST simultaneously?

[Tom Christie]

Absolutely no problem at all doing that.
The only thing that's confusing here is that `request.GET` is a misleading 
name.
The query parameters are available on any request, regardless of the HTTP 
method.

Yes.

No.
