Re: Add model item with AJAX pop up

[pa xapy]

hi
easiest way is to write separate view which will handle ajax requests (get 
and post) and render html (as a json field) and success status as response.
on frontend you will handle this response to show modal with form and 
submit it until model will successfully saved
once it happens, you can refetch your users list in select field

but I don't know any application which implement all this stack. I think 
you should handle this modal by yourself

- Do you just want to save the data you're receiving in an HTML file?

If so, you're better off just using a template library (jinja or other),
there's no need for an entire framework to do this.

- Do you want to serve the data so that it's accessible through a browser?

If so, then yes you could use django for this purpose. Django isn't limited
to fetching data from the database, it's primary job is to enable you to
serve content. You have content, you want to deliver this content, django
is for you.

- Is your console application short running? Does it do it's job, print the
content and then exit?

If so, you can just invoke the application from within a django view.
However, if the operation isn't very fast, you may want to reach out to a
task queue, but you really should worry about this in due time.

- Is your console application long running? Does it fetch data constantly?

Then you'll need to decide on how to make content available for your django
application to serve. One of the ways you could do this is have your
application send the data to a medium and have django read from that
medium. Possibly store in files, in the database, in a queue or some other
place, then django could read from there.

- Do you plan on delivering the content in realtime as you receive it?

If so, I'd suggest placing this as a different phase of implementation, but
some keywords for you to look for if you ever get to that point: javascript
polling, websockets, tornado, gevent, socket.io...

-

Good luck.

I'm a bit confused as to why you would be averse to managing a database,
assuming that you have an existing database for your users and other
content.

If you don't want to manage the page hits yourself, you may look at
something like Google Analytics to track it for you.

As far as the refresh question, I haven't researched this in detail, but as
far as I'm aware, there is no standard method for requesting refreshes that
all browsers follow, and it is difficult to determine whether a request is
an initial content load request, or a refresh request without either the
browser signaling the server with some type of request header, or some
extensive tracking of requests with timers and other heuristics on the
server side, and then of course your code has to catch all of those
scenarios.

You're trying to merge the concept of a session with a request cycle.
Unfortunately, humans think of web access more in terms of sessions, where
the HTML, images, stylesheets, authentication, etc. are a single unit
carried through while a user browsers a site, but HTTP is built to use a
single content request cycle for each resource, independent of any other
content request cycle. There are many tricks involved to provide the
'human' experience, like storing/retrieving session data for each HTTP
request (which is why your web server process should provide images and
stylesheets directly, not Django, so that those tricks are not invoked).

There's no easy answer to your question. It's possible that Analytics our a
similar service will perform those database gymnastics for you in their
optimized environments to try and remove refreshes from your counts, but
you'd have to check with them.

You should also consider the guidelines for what you are counting as a
'hit' for your counter. Perhaps a refresh after 3 seconds shouldn't be
counted, but what about a refresh after 45 minutes? What if the same user
has multiple browsers open to the same site? What if robot crawlers access
your page? Maybe you can filter those out via the reported user agent, but
what if they spoof a real browser signature and request 10K hits? What if
you have an SPA that polls the server for updates data?

Honestly, unless analytics takes care of this for you, it probably is not
worth the extra effort of saving a couple dozen refresh requests. As your
page reaches up into tens of thousands of hits, they'll probably become
statistically insignificant anyway.

The templates you included in your OP didn't have {% extends %} or {% block
%} tags in them. I asked about them and you mentioned those are the exact
templates you're using. Make sure your step templates have the correct
block references in them, otherwise your big parent template will never get
loaded. Each step of the form/view renders the entire page, not just the
section where the form is at.

Re: Polymorphic class and geomodels?

[Sergiy Khohlov]

Class Based Views has ability to include function in view from template.
 Short example:
 I have finished  small  (GTS) project  related  to  GPS system. Each car
has a array of points (car positions) and route (named as LineString in
GeoDjango).

 part of models.py


class Points(models.Model):
""" """
Car  = models.ForeignKey(Car)
Speed= models.IntegerField(default=0)
Time = models.DateTimeField()
Course   = models.IntegerField(default=0)
Altitude = models.IntegerField(default=0)
Sat  = models.IntegerField(default=1)
Point= gismodels.PointField()

 Points has connection to the Car  and has DateTime field used for correct
point sorting.
HTML page (Car) should contains array of related  object based on Car ID
and specific time range.
I add to views.py  (CarDetail class )next function:

def points(self):
""" """
timefmt= "%Y-%m-%d %H:%M:%S"
usertimezone= self.request.user.profile.timezone
try:
StartDateTime  =
usertimezone.localize(datetime.strptime(self.request.GET['StartDateTime'],
timefmt))
EndDateTime   =
usertimezone.localize(datetime.strptime(self.request.GET['EndDateTime'],
timefmt))
except:
StartDateTime  = datetime.combine(date.today(), time.min)
EndDateTime   = datetime.now()

context = super(CarDayReport, self).get_context_data()
return Points.objects.filter(Car_id=context['car'].id,
 Time__gt=StartDateTime,
 Time__lte=EndDateTime).order_by('Time')

  Time range is set via html template. Car ID is  also known.   Not hard
way to do.,

Serge

After upgrading from 1.8.8 to 1.9.2 migration applies succesfully but ends with an error

[Richard la Croix]

I just upgraded from 1.8.8 to 1.9.2 and using Python version 3.4.3.

The included Django migrations (admin.0002_logentry_remove_auto_add and 
auth.0007_alter_validators_add_error_messages) applied succesfully.

The following migration of a model update failed with error:
   TypeError: can't multiply sequence by non-int of type 'tuple'

However, the migration actually went thru correctly and is inserted into 
the 'django_migrations' table.
When I execute 'migrate' again, it responds with 'No migrations to apply.' 
and then again error message:
   TypeError: can't multiply sequence by non-int of type 'tuple'

Anybody had a similar experience or has an idea?

regards,
Richard

Re: Django formtools wizard produces blank page (No error returned)

[Martín Torre Castro]

If I understand well, you mean that my form templates have to extend the
main wizard template. Is that correct?

In previous versions this was achieved by writing template_name =
'main_wizard_template.html' into the subclass of WizardView. Am I wrong?

So, with {% extends 'registration/test_wizard.html' %} in
*registration/test_step1.html
and **registration/test_step2.html* it should work.

I will try tonight.
Thanks.

AttributeError When Overwritting AUTH_USER_MODEL in Test Cases

[Aubrey Stark-Toller]

Hello,

When I override the AUTH_USER_MODEL setting to "auth.User",  when
AUTH_USER_MODEL in settings is not set to "auth.User", in 
either a TestCase or individual test, and then try to access the objects
attribute on the user model, I get an AttributeError. 

The exact error I get is:
AttributeError: Manager isn't available; 'auth.User' has been swapped
for 'None'

I've found this to be the case in both Django 1.8 and 1.9.

This is easily reproducible in a fresh project : create a boilerplate
project with a boilerplate app, add a new user model (call it
CustomUser) to the app and set to AUTH_USER_MODEL to CustomUser, and add
the following test case to the app:

> from django.test import TestCase, override_settings
> from django.contrib.auth import get_user_model
>
> class MyTestCase(TestCase):
>@override_settings(AUTH_USER_MODEL = 'auth.User')
>def test_custom_user(self):
>UserModel = get_user_model()
>UserModel.objects.all()

get_user_model() retrieves the correct model but accessing objects
attribute gives the stated error when running the test.

If I throw in another user model (say CustomerUser2) and write a test
such as:

>@override_settings(AUTH_USER_MODEL = 'another_app.CustomerUser2')
>def test_custom_user(self):
>UserModel = get_user_model()
>UserModel.objects.all()

this works fine, and if I unset AUTH_USER_MODEL in settings again
everything works as expected.

Perhaps someone can shed some light on this behavior?

Cheers,
Aubrey

Re: How to show python data on html

[Derek]

Depending on what your console app does or needs to do, you can also look 
at Flask as a way of serving up HTML pages to your browser; see 
http://flask.pocoo.org/docs/0.10/quickstart/  - you then do not have to use 
a database with models if those are not needed.  Django is great but not 
always appropriate.

Right place to decrypt/decode data from DB before passing it to UI without affect data in DB itself.

[learn django]

Hi,

I store some data like email text, headers and from email address in 
encoded format in the database.
I want to have a  page where I can display all this information in readonly 
format.

What is the ideal place & way to decode this information and pass it to 
django UI.

I was thinking of reading all the information in my views.py.
But then I don't want to affect my DB. aka information in DB should remain 
encoded.

eg.

class FooViewSet(viewsets.ModelViewSet):
queryset = Message.objects.all()

Message object has headers, body and from fields which are encoded before 
storing in db.
If I perform any operation on queryset those changes will be reflected in 
DB so I cannot do that.

If I do something like below then I get exception for using list as 
queryset becomes a list object instead of queryset object.

class FooViewSet(viewsets.ModelViewSet):
queryset = list(Message.objects.all())
for obj in queryset:
body = base64.b64decode(obj.body)
obj.body = body

Running automated expiration date events

[Rod Delaporte]

I have a field of a model that changes states but I need to automatically 
modify that value after an expiration datetime has come. Is there a way to 
do this?

Here is an example:

class Post(models.Model):
created_at = models.DateTimeField(auto_now_add=True)
languages = (
('1', 'active'),
('2', 'inactive'),
)
language = models.CharField(max_length=20, choices=languages, 
default='english')
duration = models.DurationField(blank=True, null=True)
expires = models.DateTimeField(blank=True, null=True)
updated_at = models.DateTimeField(auto_now=True)

@property
def active(self):
return self.expires > localtime(now())

def save(self, *args, **kwargs):
self.created_at = localtime(now())
self.expires = self.created_at + self.duration
return super(Post, self).save(*args, **kwargs)


The problem I have is that I have to call the active function property to 
check if it's True or False and I'm looking for a way that this can be done 
automatically so the database updates itself.
I've been thinking about Django-cron but I can't chose when to call the 
active function, this should be done for itself.

Is this possible?

Re: Add model item with AJAX pop up

[guettli]

There many auto-complete fields. Adding an item in a popup is needed very 
often. The django-admin does it, too.

For me it is strange that there is no reusable widget for this.

Re: Running automated expiration date events

[Luis Zárate]

Maybe with celery and Django celery you can do what you want.  There is a
functionality called crontab that is manage by models with Django celery.
So you can create cron task that will call when you need with a reference
to you model.

As an interesting problem, think in the moment of update you model if you
use a cron task, specially when you change de date.

Re: How to show python data on html

[Luis Zárate]

Database models approuch only the most popular form of manipulate data, but
django is MVT so you could have different representation of the "M" (eg.
External API) and full use of "VT".
An example.

def myfunc(request):
 mydata = my_dict_get_by_api_call()
 return render(request, 'template.html', mydata)

Suppose that mydata has 'myobj' as a key  so in template.html you can do

{{myobj}}

Of course you could use URLs to access your view :)

[Luis Zárate]

You are using django rest, sure.

Why Message doesn't have an function as a property that return the
encrypted .

What python package is accurate to detect languages and count words?

[Allison]

I am trying to detect languages, so far I have used langdetect, langid. I 
heard goslate is blocked by Google, is there any package as good as 
goslate? It was simple and direct? Or would you recommend a python package 
for detecting languages and counting words? 

Thanks in advance, 

Allison

This wil not work for different reasons.
First one is about Python scope. Doing this will get you a fixed list of 
Message unless you restart the server.
Second is you’re using a generic view that expects QuerySet as you’ve noticed. 
Overriding get_queryset would get somewhat bette result but it still wouldn’t 
work as QuerySet are expected for pagination and filtering.

The best place to perform that are to_representation and to_internal_value for 
that field.
You should have a look at the custom fields 
(http://www.django-rest-framework.org/api-guide/fields/#custom-fields 
) for 
guidance about how to handle that.

Xavier,
