Re: ANN: django-otp and friends: one-time passwords and trusted agents

[Jason Arnst-Goodrich]

I'm glad you saw my message - if nothing else just so you know this project 
is appreciated.

I've got it working with Google's Authenticator.

I had initially planned to use another project out there for my OTP needs 
(there's a small number of them that work 'out of the box') because yours 
took a little extra effort to hook up.

I ended up going back and using yours though because it's truly in another 
class. I have the basics working right now.

I have a couple of questions - I'm trying to make a self service system for 
allowing users to enable two factor authentication.

If I loop django_otp.devices_for_user to allow them to manage their 
existing devices, It's hard to link to a details page for each device. It 
might help to have a get_absolute_url() defined on the model (which can be 
overridden is settings). Right now I'm piping it to a template filter using 
ContentTypes. TBH, I'm pretty new to dealing with this pattern so I might 
be thinking about it wrong.

Lastly, what I'll probably end up doing is building a decorator that 
basically says "require two factor auth if they have it turned on".

I guess if I had a wishlist it would be to see a baseline for allowing uses 
to manage their own OTP devices as well as that decorator built in. I 
understand it's probably out of the scope of what you have right now. I'd 
still like like to see something that ties it up nicely. That's basically 
what I'm building right now except I don't trust my build to work in anyone 
else's setup - although if I have time I'll see if I can go back and 
refactor it.

Anyways, thanks again for the work you've done - it's outstanding.

 Thanks for your suggestions. Dumping data isn't the entire problem - 
 which
 is this:

 There will be an *ongoing* need to add new data from tables in one 
 database
 to the same-named tables in another database on a remote machine. Two 
 of the
 tables are in a m2m relationship.

I read the 
sql-createforeigntable
 page 
and I think I know what a distributed database is versus a replicated 
database. But I have no idea why I would choose one over the other. Can you 
suggest?

In any case, I'm 99% sure I should "refactor" (if that's the right word) 
the reference tables out of the database into a separate database and get 
to that data via a Django router. Not sure how I'll do that just yet but it 
has to come ahead of a distribute/replicate solution.

Thanks

Mike

Thanks, I'm glad you like it. I can look into some kind of demo, although 
Authenticator support is pretty simple. The documentation already links to 
Google's URI scheme[1], which has all of the details. All you have to do is 
create a TOTP or HOTP device (usually the former), encode the key with base32, 
build a URI as documented, and render a QR code for the user to scan. 
Alternatively, the user can also type the base32-encoded key in manually.

Try this ...

return socket.getfqdn()

This may or may not be what you want.

In any case, you will need to include the domain name of the host (to 
which you distribute your app) in settings.ALLOWED_HOSTS [1]


Additionally, you might want a utility method to return the desired url 
prefix in your get_absolute_url() methods. Perhaps like this if you use 
the contrib.sites app ...


from django.contrib.sites.models import Site
def get_domain():
return Site.objects.get_current()

... which requires that you find some way to include the client domain 
in the Site table and insert that site.id into your various client's 
settings.SITE_ID


Alternatively, you could just parse the fully qualified domain name 
returned by socket.getfqdn() and use it in the above get_domain() or 
your get_absolute_url() methods.


[1] I follow the 2 scoops advice and have separate settings files for 
separate servers. I edit them manually for the very few servers my stuff 
runs on. AND I make sure the sites table is identical on all sites so I 
don't have to think about it ever again. YMMV.

Overriding CSS class for form widgets with generic editing views

[Branko Majic]

Hello all,

I'm interested in finding-out the best practices for overriding the
form widgets styling by assigning appropriate CSS classes to them. In
particular, I'm trying to determine the best place (tm) to modify that
information when using the generic editing views
(CreateView/UpdateView).

Right now I do this by overriding the get_form in a CreateView (for
example), and having code along the lines of:

%
form = super(ProjectCreateView, self).get_form(form_class)
form.fields["name"].widget.attrs["class"] = "span6"
form.fields["description"].widget.attrs["class"] = "span6"

return form
%

Is this a good way to do it in order to reduce writing lots of
boilerplate, or should it be better to use a custom ModelForm +
FormView?

Best regards

jquery in django

[Christian Erhardt]

Hey Harjot,

i can't provide an easy answer to your question. An Ajax enabled search with 
django is nothing, that one programs in 30 minutes especially not if he has no 
understanding of query and or ajax.

I'll try to give you some hints but not a complete plug n play solution. 

First things first. Jquery is a Javascript framework. One function it provides 
is to handle ajax requests. In short: Javascript running in the users browser 
calls the server  and with help of jquery you modify the DOM of the html page. 
So you don't have to reload the html page for each request. 

Now django comes to play. Django just handles the request. So you will need a 
page which will return search results for a query you submitted. If you call a 
django page it usually returns a html page. For ajax calls you would not work 
with html. Most pages use json to serialize data. There is a plugin called 
tasrypie which we use. It provides an ajax endpoint. As i recall it has a built 
in search function. Maybe you try this first. There are more high sophisticated 
search engines for django... but i'd give tastypie a try.

If everything is set up correct you can call an endpoint for your model with a 
jquery ajax call.

But this is acomplex task!

Regards

I was looking for a django package that I could integrate into my app
that would allow me to pass it a long URL and it would return a short
one and then if that short URL was used it would redirect to the
original long one. But I've already implemented something myself and I
have it working.

You should be able to do it with the django .extra() method easy enough.  I 
believe you can also make a soundex index on columns to improve the 
performance.  

The python jellyfish library is nice for pre-calculating phonetic strings 
and storing them in the database to compare against, or for small data sets 
that you want to process in python.

A third option is something like 
https://github.com/niwibe/djorm-ext-pgfulltext  which uses postgres full 
text search.  The full text search uses tokens that are normalized.  I'm 
not sure it it would normalize amanjit to amanjeet with the default 
configuration, and may be overkill for what you want.

Re: jquery in django

[Rafael E. Ferrero]

Harjot... the answer to your question is YES you can use ajax in yours
project... but you do that on yours templates.

you must to download http://code.jquery.com/jquery-2.0.2.min.js in some
directory where django can find when render your template, then in your
template must add this line that Sandro says



or directly use this without download anything (but need an internet
connection):
http://code.jquery.com/jquery-migrate-1.2.1.min.js";>

here http://learn.jquery.com/ you can learn everythin of jquery

Re: jquery in django

[François Schiettecatte]

Hi

jQuery is not a search engine but a JavaScript library which helps you build 
interactive web pages (and much more, see http://jquery.com ) .

If you want a search engine, I suggest you look at SOLR, there are a number of 
python libraries which would help you interact with that. A word of warning, 
SOLR is very powerful/flexible so there is complexity there.

Best regards

François

Say what you try, show your models and your code and maybe we can help or
try to find a package that suit your needs:

Your first post was not django related and now is lacking information, we
can't guess what you're doing correctly or wrong.

Re: Render dynamic form based on meta data

[François Schiettecatte]

Avishay

I am a little confused, the form looks fine to me, are you trying to send the 
content to django for validation when the user clicks the 'Validate' button? 
You can do that using a REST call to django, or POST the form to django, either 
way you are going to have to write some backend code to deal with the input.

I am workng on an automation project in which I want to make search
which should be a very good search meanwhile it is working but it is a
simple search. I want that when I type something in search box it
should display the clients from database just like google does in its

Adding to Jacky Tian's reply, if you are running the django dev

is added to INSTALLED_APPS in settings.py

See docs about these settings here -

Re: no style in admin pages; learning from djangobook.com

[Jacky Tian]

Are you using the development server with `python manage.py runserver`? If 
you are, the static files for the admin should just work. If they don't, 
you may have messed up something in your settings.py. 

Otherwise, if you're serving your project from a webserver like Apache or 
nginx, run `python manage.py collectstatic` to consolidate the admin static 
files into your STATIC_ROOT directory. You'll probably have to fiddle with 
your web server configuration to serve files from STATIC_URL from 
STATIC_ROOT before you get it to work.

  So I have:
 views.py:
 def datatables(request):
 if request.method == 'POST':
 form = DataTableForm(request.POST)
 if form.is_valid():
 model_instance.save()
 return redirect('myapp/tabspec.html')

 form = DataTableForm()
 return render(request, 'myapp/datatables.html', {
 'form': form,

 template datatables.html:
 
 
 
 Make Tables
 
 
 >>> enctype="multipart/formdata">{% csrf_token %}

  {{ form.datFile.label_tag }} {{ form.datFile }} 
  {{ form.structFile.label_tag }} {{ form.structFile }} 
  {{ form.bannerVar.label_tag}} {{ form.bannerVar }} 
  {{ form.stubVar.label_tag}} {{ form.stubVar }} 
  {{ form.stubNets.label_tag }} {{ form.stubNets }} 

 

 
 

 models.py:
 class DataTable(models.Model):
 datFile = models.CharField(max_length = 200)
 structFile = models.CharField(max_length = 200)
 bannerVar = models.CharField(max_length = 50)
 stubVar = models.CharField(max_length = 50)
 stubNets = models.BooleanField()

 and forms.py:
 class DataTableForm(forms.ModelForm):
 class Meta:
 model = DataTable

 The form shows fine (see image), but when I click the button it goes
 back to the index page, which isn't what I wanted to happen.  Any thoughts
 on where I am going wrong?

URL shorteners

[Larry Martell]

I'm looking for a URL shortener I can use with my django project. I
want to be able to email a short link to someone that will expand to
the 'real' URL. Googling I see there's quite a few different URL
shorteners. Anyone here have any experiences with them they would like
to share? Which one would be the best for my type of use case?

Thanks!

template datatables.html:

Two scoops of django is great. This book have many good practices and also

Freelance Django - London (£1500)

[George Kazarian]

We are a London based online retail startup (currently in test-launch). The 
website is up and running with a fully functioning payment system. Our soft 
launch is planned for July 25th.

The website requires some changes and UX improvements before we open up to 
public. The following sections on the website need specific attention: my 
account section, homepage and sign-up process.

We are looking for a creative and diligent developer who can dedicate a few 
days per week before our soft launch. Post-launch involvement also needed 
for testings and tweaks.

Agreed good tutorials would show steps and then point to resources for
further reading,

At this point though it appears there is a scarcity of good tutorials for
current Django.

Sounds like you want replication from one database to another. Recent
versions of Postgres have built in support for what they call "log
shipping" or "streaming replication", where logs of updates are
transferred to backup servers and executed:

http://www.postgresql.org/docs/current/static/warm-standby.html

This requires some manual setup of your servers to transfer the logs.

There are other forms of replication, postgresql actually provide a
useful table listing the various solutions, their pros/cons, and links
on how to implement them. Lots of the solutions are not part of
postgresql itself, but use third party packages like slony to effect
the replication. See here:

Virtualenv, pip etc are not features of Django, they are features of
python. It is right that Django mentions them in places, it is doubly
right that it does not attempt to duplicate the fine documentation
that pip and virtualenv possess themselves.

Not showing a model from the models' list in admin

[Victor]

Issuing the "localhost:8000/admin"  request in the browser I am presented with 
the list of all registered models.
I don't want one of this  models  to be visualized in that list even though it 
is widely used and referenced by other models. 
How can I do that without unregistering the model?

It leads to bits of info for each python framework but nothing

Yep, they say "come join rails", and not "come join Ruby". This
encourages people to look for "rails best practices" and not "ruby
best practices". Conversely with python/django.

Templatetag variable resolution choices (Python literals)

[Marc Kirkwood]

OK, so I've got a template tag and a corresponding Node class. In order to 
check the value of two template variables in the Node.render method, I'm 
using the template.Variable class as specified in the docs. However, I'm 
wondering if there is any point to this, given the extra lines of code that 
are required to instantiate the class in the Node.__init__ method, then 
resolve each of the two variables within separate try-except blocks in case 
of a template.VariableDoesNotExist error. Given that both the variables are 
Python literals (boolean and list) and context.get('name', default) works 
as expected without the extra boilerplate, I'm wondering why it's not a 
documented way of doing this.

In summary, the following types of variable lookup give identical results 
when dealing with Python literals -- except that using the context directly 
removes the need for the try-except block and also eliminates the Django 
template.Variable checking code, which is redundant in this case:


class ExampleNode(template.Node):
def __init__(self):
self.a1 = template.Variable('a_variable')

def render(self, context):
try:
a1 = self.a1.resolve(context)
except template.VariableDoesNotExist:
a1 = False

a2 = context.get('a_variable', False)


I'll add once again that these variables are simply set in a view context 
as Python literals.

Is this search function a query like
MyModel.objects.filter(usernamename=username, ...) or something more
specific ?

Haystack is a full text search application, it build an index specific for
full text search which means it's not suited for the search you are looking
to do (also it takes a lot of memory).

It depends... can you write a query in the form of
MyModel.objects.filter(foo=bar, spam=egg) where you document each fields so
that we can know better what your are trying to achieve ? Real data is not
significant, but full scope of the problem you are trying to solve is.

Hey L :),

fwiw, this should work if you want to install via pip currently:
pip install -e git+https://github.com/django/django.git@1.6b1#egg=django

The docs [0] do say that pip install django==1.6b1 should work though, so
I'm guessing someone is going to push to pypi soon :-)

Re: Get Form from string?

[Sanjay Bhangar]

Hey MacVictor,

So when I needed to do something similar, I landed up hard-coding a dict
with form-name -> form-class in my model definition. Honestly, there is
probably a better way to do it, but that worked fine for my use-case,
though it did feel slightly "not right". Any-how, fwiw, I did something
like:

from forms import FormA, FormB, FormC
class Foo(models.Model):
  ...
  forms = {
'SomeFormA': FormA,
'SomeFormB': FormB,
'SomeFormC': FormC
  }

And then in your view, something like:
form = model.forms[] .. etc..

I'm guessing from your email that what you need is something similar, and
perhaps someone from the list has a better idea than the above to do it ..

Hope that helps, though ..

All the best,
Sanjay

Python Fabric manage.py problem

[Eduardo Basílio]

I use Python Fabric to deploy. Works great for accessing the remote server, 
install dependencies, run linux commands, etc..

But when I try to run *file commands manage.py Django*, NOT work!


Example of my fabfile.py:

with prefix ('source/home/user/env/bin/activate'):

with cd ('path/to/your/project/django'):

*run ('python manage.py help --settings=path.for.settings')*


Fatal error: runstrong text() received nonzero return code while executing 
one!


I've tried putting a --noinput but the error remains:

*run ('python manage.py help --settings=caminho.para.settings --noinput')*

Does anyone know how to solve?

dajaxice file cannot be found

[no body]

I am usering django_dajax 0.9.2 and django_dajaxice 0.5.5 for my current
project. This is how I configure it


#settings.py

*MAIN_DIR = os.path.dirname(__file__)
PROJECT_DIR = MAIN_DIR.rsplit(os.sep, 1)[0]

# Example: "/home/media/media.lawrence.com/static/"
STATIC_ROOT = os.path.join(PROJECT_DIR, 'static')

# URL prefix for static files.
# Example: "http://media.lawrence.com/static/;
STATIC_URL = '/static/'

# Additional locations of static files
STATICFILES_DIRS = (
# Put strings here, like "/home/html/static" or "C:/www/django/static".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
os.path.join(MAIN_DIR, 'static'),
)

# List of finder classes that know how to find static files in

STATICFILES_FINDERS = (
'django.contrib.staticfiles.finders.FileSystemFinder',
'django.contrib.staticfiles.finders.AppDirectoriesFinder',
'dajaxice.finders.DajaxiceFinder',

and my urls.py
*
from dajaxice.core import dajaxice_autodiscover, dajaxice_config
dajaxice_autodiscover()

)

urlpatterns += patterns('',

...*


With this settings, I am enable to use these libs in my local machine.
However, when deploying to the client machine, the file dajaxice.core.js
cannot be found (see it on firebug). When use *python manage.py collecstatic
*, I see that that file is saved into the folder temp (*Copying
'/tmp/tmpsiiuMx'*). The rendered link is correct

**

and there is indeed that file under the /static/dajaxice folder, but still
the browser complains about cannot find that file. Do you have any idea
about this ?
