Sort CommaSeparatedIntegerField in Django Admin
I'm working on a model witch has an CommaSeparatedIntegerField in wich i store the order of some Images witch I'm getting from filers FolderField. class Gallery(models.Model) […] folder = FilerFolderField(blank=False) order = models.CommaSeparatedIntegerField(max_length=300, blank=True) Now I'm looking for a way to be able to change this order easily (e.g. by drag and drop) in the Django admin P.S. I know that FilerFolderField is not documented yet and could be removed, and also that CommaSeparatedIntegerField is deprecated. -
Convert Django QuerySet to Pandas Dataframe and Maintain Column Order
Given a Django queryset like the following: qs = A.objects.all().values_list('A', 'B', 'C', 'D', 'E', 'F') I can convert my qs to a pandas dataframe easily: df = pd.DataFrame.from_records(qs.values('A', 'B', 'C', 'D', 'E', 'F')) However, the column order is not maintained. Immediately after conversion I need to specify the new order of columns and I'm not clear why: df = df.columns['B', 'F', 'C', 'E', 'D', 'A'] Why is this happening and what can I do differently to avoid having to set the dataframe columns explicitly? -

Directory structure for large django rest framework apps
We've been developing an application using django and django rest framework for a while now and we're reaching a point where our viewsets.py and serializers.py files are getting too large. Our current structure is very similar to what many posts describe (eg. Large Django application layout) but they only seem to suggest creating new applications as the best route to maintaining manageable directories. Our current set up is as follows: project app1 models.py serializers.py viewsets.py ... app2 models.py serializers.py viewsets.py ... For our use case, our models.py are small and discrete enough that I don't think we need to separate them out into separate applications, but I'm not sure what else we can do. -

Why do django channels produce unexpected results sometimes?
I am developing a web socket based Django API which has 2 different API endpoints. For this, I am using Django channels with Redis as the backend channel layer. The first endpoint, /request will allow a user to start a request running on the server. It receives 2 parameters which are ConnID and Request Timeout. The second endpoint, /status will return a dictionary of all the running jobs with their remaining time. ex {'1':5, '2':34} Below is the consumer.py file from django.http import HttpResponse import json import time CONN_TIMEOUT = {} KILL_LIST = {} def _execute(message, connId, timeToSleep): global CONN_TIMEOUT, KILL_LIST CONN_TIMEOUT[connId] = timeToSleep KILL_LIST[connId] = 0 isKilled = False for i in range(0, timeToSleep): if KILL_LIST[connId] == 0: time.sleep(1) CONN_TIMEOUT[connId] -= 1 else: isKilled = True break CONN_TIMEOUT.pop(connId) KILL_LIST.pop(connId) if isKilled: message.reply_channel.send({'text':str('{\'status\':\'Killed\'}')}) else: message.reply_channel.send({'text':str('{\'status\':\'Ok\'}')}) def ws_message(message): global CONN_TIMEOUT print 'MSG' jsonObj = json.loads(message['text']) timeToSleep = int(jsonObj['time']) connId = jsonObj['connid'] print 'ConnID ' + connId + ' time: ' + str(timeToSleep) if CONN_TIMEOUT.get(connId) > 0: print 'Passing' pass else: print 'Starting new thread' _execute(message, connId, timeToSleep) def ws_kill(message): global KILL_LIST print 'KILL' print KILL_LIST jsonObj = json.loads(message['text']) connId = jsonObj['connid'] if KILL_LIST.get(connId) == 0: KILL_LIST[connId] = 1 message.reply_channel.send({'text':str('{\'status\':\'Ok\'}')}) else: message.reply_channel.send({'text':str('{\'status\':\'Invalid … -

How do I set up a PostgreSQL database for use with PostGIS and GeoDjango?
The Django docs say to use createdb -T template_postgis geodjango but I already have a database set up. While trying to find out what this actually does and a way to apply it to an existing database, I found this on postgis.net: -- Enable PostGIS (includes raster) CREATE EXTENSION postgis; -- Enable Topology CREATE EXTENSION postgis_topology; -- fuzzy matching needed for Tiger CREATE EXTENSION fuzzystrmatch; -- Enable US Tiger Geocoder CREATE EXTENSION postgis_tiger_geocoder; In trying to figure out what Tiger is, I found this in the postgis docs: psql -d [yourdatabase] -c "CREATE EXTENSION postgis;" Topology is packaged as a separate extension and installable with command: psql -d [yourdatabase] -c "CREATE EXTENSION postgis_topology;" How do I ready my current Django database for use with PostGIS and GeoDjango?

Textblob logic help. NaiveBayesClassifier

But this doesnt seem the case and i have been altering the logic in many ways and still unsuccesful. The problem is if the tweet is positive or negative yes the algorithm does recognise that they are. However i want it to save 'normal' if they … -

Can I lookup a related field using a Q object in the Django ORM?
In Django, can I re-use an existing Q object on a related field, without writing the same filters twice? I was thinking about something along the lines of the pseudo-Django code below, but did not find anything relevant in the documentation : class Author(Model): name = TextField() company_name = TextField() class Book(Model): author = ForeignKey(Author) # Create a Q object for the Author model q_author = Q(company_name="Books & co.") # Use it to retrieve Book objects qs = Book.objects.filter(author__matches=q_author) If that is not possible, can I extend an existing Q object to work on a related field? Example : # q_book == Q(author__company_name="Books & co.") q_book = q_author.extend("author") # Use it to retrieve Book objects qs = Book.objects.filter(q_book) The only thing I've found that comes close is using a subquery, which is a bit unwieldy : qs = Book.objects.filter(author__in=Author.objects.filter(q_author)) -
Convert datetime printed by Django, to a different datetime format
My web application works with datetime(s) as timestamps, which according to Django's error messages need to be in the following format: YYYY-MM-DD HH:MM[:ss[.uuuuuu]][TZ]. I display these timestimes on multiple occasions on the web application, where they're displayed in the following format: 12. June 2017 10:17. Now, the user is able to choose and submit the displayed timezones, which are then processed by the server. The server then error's because the format isn't correct. How do I convert the format printed by Django on the web app (12. Juni 2017 10:17) to the format, required by Django for further processing (YYYY-MM-DD HH:MM[:ss[.uuuuuu]][TZ])? -
Disable data migrations in Django when creating test database
I have an app with a fair number of migrations including data migrations to set foreign keys on some models. When I try to run tests.py, it fails because the data migration is querying the database for data that doesn't exist in the test database. Is there a way to disable the data migrations? (I want to keep schema migrations). Or alternatively to load data from fixtures before running the data migrations? -

My url is shown below like: url(r'^register/$', views.register, name='register') The function in my views.py is like: def register(request): """register""" if request.method != 'POST': #we present a blank form form = UserCreationForm() else: #the post the data the users have just filled form = UserCreationForm(data=request.POST) if form.is_valid(): new_user = form.save() # we use the date to redirect our user to the page of login authenticated_user = authenticate(username=new_user.username, password=request.POST['password']) login(request, authenticated_user) return HttpResponseRedirect(reverse('learning_logs:index')) context = {'form': form} return render(request, 'users/register.html', context) And my register.html: {% extends "learning_logs/base.html" %} {% block content %} <form action="{% url 'users:register' %}" method="post"> {% csrf_token %} {{ form.as_p }} <button name="submmit">Register</button> <input type="hidden" name="next" value="{% url 'learning_logs:index' %}"/> </form> {% endblock content %} when I do the register, it goes wrong like, MultiValueDictKeyError: "'password'" Can some one have a look and give me a hand?

View not receiving POST data from image upload page
I've seen similar questions but can't figure this out, I have a program that upload pictures on a model: views.py: def upload_pic(request): if request.method == "POST": image_form = ImageUploadForm(request.POST, request.FILES) if image_form.is_valid(): image_form.save() return HttpResponse('success') else: return HttpResponse('fail') return render(request, 'tracker/upload_pic.html', {"image_form": image_form}) template: {% load staticfiles %} <!DOCTYPE html> <html> <body> <form method="POST" enctype="multipart/form-data">{% csrf_token %} {{ image_form.img }} <input type="submit" value="submit" /> </form> </body> </html> urls.py: urlpatterns = [ url(r'^upload_pic', views.upload_pic, name='upload_pic') ] Just trying to save to the user model so I can retrieve it later, but I can't access any POST data, I've also tried add action = "{% url upload_pic %}" to my form in the HTML template, but I get the NoReverseMatch error -
Customizing Rosetta Django interface.
I am working on a project that has extended the Django Admin Site and has included different styling for the templates. The project requires a translation extension, and I downloaded the Rosetta Django app, but now i want to also extend the Rosetta Django user interface to use the same styling that we have made for the customized admin site. Is there a way to do this?
