Django how to merge query results
I have an ArrayField with choices and i'm trying to filter the choices: PAYMENT_CASH = '0' PAYMENT_CARD = '1' PAYMENT_BANK = '2' PAYMENT_ONLINE = '3' PAYMENT = ( (PAYMENT_CASH, _('Cash')), (PAYMENT_CARD, _('Card')), (PAYMENT_BANK, _('Bank')), (PAYMENT_ONLINE, _('Online')), ) options = ArrayField(models.CharField(max_length=1, choices=PAYMENT, default='0'), size=4) When i use Location.objects.filter(city__id='683506').values_list('options', flat=True) it returns me <QuerySet [['0'], ['0', '1', '2', '3'], ['0', '1', '2'], ['0', '1'], ['0', '1', '2', '3']]> I wish to get all the options that are used. How can i merge the query or make them into a list and merge them? This is what i wish to get ['0', '1', '2', '3'] -
StreamBlock instance throws exception "AttributeError: 'str' object has no attribute 'block'"
I am using the example project provided by Wagtail. The StreamField gets as argument A DemoStreamBlock class DemoStreamBlock(StreamBlock): h2 = CharBlock(icon="title", classname="title") h3 = CharBlock(icon="title", classname="title") h4 = CharBlock(icon="title", classname="title") intro = RichTextBlock(icon="pilcrow") paragraph = RichTextBlock(icon="pilcrow") aligned_image = ImageBlock(label="Aligned image", icon="image") pullquote = PullQuoteBlock() aligned_html = AlignedHTMLBlock(icon="code", label='Raw HTML') document = DocumentChooserBlock(icon="doc-full-inverse") Then in the Page class I'm instantiating a variable e.g. class BlogPost(Page): blog_text = StreamField(DemoStreamBlock()) content_panels = Page.content_panels + [ StreamFieldPanel('blog_text') ] The first time I run the migrations Django doesn't want me to put a default value because of the non-nullable field that I am adding. However, if I want to add another StreamField field I am prompted to add a default value: class BlogPost(Page): blog_text = StreamField(DemoStreamBlock()) blog_short_text = StreamField(DemoStreamBlock()) content_panels = Page.content_panels + [ StreamFieldPanel('blog_text'), StreamFieldPanel('blog_short_text'), ] You are trying to add a non-nullable field 'blog_short_text' to blogpost without a default; we can't do that (the database needs something to populate existing rows). Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a > null value for this column) 2) Quit, and let me add a default in models.py I am choosing 1 and then enter … -
Ubuntu service Upstart or SystemD, Django development server as Service
I've been working around with Python & Django Framework for a while with Ubuntu 16.01. Since I used Django with Q system (Celery) and some others Enhancement Apps. When I try to run all the apps each time, I need to run development server "{python manage.py runserver}", then running Celery Worker "{celery -A filename worker -l info}". Each time I working, it takes me minutes to enter the directory and start it up. I surf around and come up with the idea of setup it as service. Example, service name: "pyd". I just need to run "{sudo pyd start}" -> then Django Development Server and Celery will start, and if I run "{sudo pyd stop}" -> then Django & Celery will stop. I try to search around, and things start to confuse me between "Upstart" and "Systemd". Could any one suggest, me how to make both Django and Celery as Service run in Ubuntu ? between "Upstart" & "Systemd" which one is better ?? Source code to indicate sample is appreciated. Thank -

unable to access django website from URL but accessible from IP address
I have installed django on Amazon lightsail, I can access my website through the static server IP address. My domain is hosted on Godaddy. I change the Name Server in GoDaddy. But still when I try to access my website through domain name it shows me Nignx welcome page. Welcome to nginx! If you see this page, the nginx web server is successfully installed and working. Further configuration is required. For online documentation and support please refer to nginx.org. Commercial support is available at nginx.com. Thank you for using nginx. In my django settings.py I have given only the IP address ALLOWED_HOSTS = ['YOUR_AMAZON_LIGHTSAIL_IP'] And in Nginx file, I also added only the IP address. server { listen 80; server_name YOUR_AMAZON_LIGHTSAIL_IP; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/ubuntu/django_project; } location / { include proxy_params; proxy_pass http://unix:/home/ubuntu/django_project/django_project.sock; } } I am using Gunicorn and Nginx on my hosting server. -
Django deadline alert
I am building a management application for a company. One of the things the application can do is start new projects. The model here for is: ` class Project(models.Model): employees = models.ManyToManyField(settings.AUTH_USER_MODEL) division = models.ForeignKey(Division) client = models.ForeignKey(Company) description = models.CharField(max_length=120) timestamp = models.DateTimeField(auto_now_add=True) deadline = models.DateField(blank=True) active = models.BooleanField(default=True) ` As you can see in the model a employee can set a deadline for their project. I need to able to send the user notifications if they are close to their deadline. For example, if the deadline is in two days, the user will get a notification like "Your deadline for projectname is over two days". So basically what I need is a deadline timer. What is the logic for this? I don't really know where to start with this? -

How to record the operation logs that influenced by update methods with django-auditlog?
Recently, i have been dedicated to accomplishing the log logging function in the background. However, there exists a problem that i failed to figure out. Concretely, when it comes to record soft delete, as we all kown, the moment the field 'is_delete' transforms from False to True, the interface that including save methods can record relevant change, but this situation is not holding true for update methods. What i want to konw is that how to solve this problem without creating some corrlative tables. In terms of code, for example, if the current operation is 'save', model.is_delete=True,model.save() that is to say, After model.is_delete equals to constant 'True' and the save method of model is invoked, a new record will be inserted into the table called auditlog_logentry. Nevertheless, if update methods are conducted,i.e., model.update(is_delete=True), no records will be recorded in auditlog_logentry. I will be very appreciated if you can give me some hints or solutions. Looking forward to making progress together with you. Thanks a lot. -
Connection errors due to webpage navigation
I am having some trouble with connection errors in my Django app when a user navigates to different page before AJAX call is finished.

Distance query for arbitary points with GeoDjango not working as expected - distance calculation seem off
I'm building a world-map and want users to be able to look-up locations and have them be sorted by distance from anywhere in the world. I'm using GeoDjango to calculate distances, however the distances returned seemed wrong so I checked them against geopy's calculations. The distances differ significantly to the point that if the results are sorted by the DB vs geopy values they would not be in the same order. I'm assuming the geopy values are correct so I'm wondering, is there something wrong with the way I implemented GeoDjango? Is it working as it should? Does this have something to do with trying to calculate distances for the entire world and not just a specific area which could have a srid? views.py pnt = GEOSGeometry('POINT({} {})'.format(latitude, longitude), srid=4326) qs = Place.filter(point__distance_lte=(pnt, D(km=radius*2))).annotate(distance=Distance('point', pnt)).order_by('distance') settings.py DATABASES = { 'default': { 'ENGINE': 'django.contrib.gis.db.backends.postgis', 'USER': '', 'NAME': 'places', 'HOST': '127.0.0.1', 'PORT': '5432', } } models.py: from django.contrib.gis.db import models from geopy.distance import vincenty class Place(models.Model): latitude = models.DecimalField(max_digits=10, decimal_places=6, null=True, blank=True) longitude = models.DecimalField(max_digits=10, decimal_places=6, null=True, blank=True) point = models.PointField(null=True, geography=True) def distance_from_target(self, target_lat, target_lon): if not target_lat or not target_lon: return None instance_point = (self.latitude, self.longitude) target_point = (target_lat, target_lon) … -
Implement a 'trending' algorithm to sort a queryset of Posts

Would I make a custom method under in PostScore: @property def trending(self): score = self.upvotes - self.downvotes time = self.post.date print('TIME:', time) return score or would I sort it in my views?: posts = Post.objects.all().filter(entered_category=category).annotate( score_diff=F('score__upvotes') - F('score__downvotes'))\ .order_by('score_diff') -
Django 1.11 CreateView pass URL parameters
I am using Django 1.11 and I'm struggling to understand how I can pass URL parameters to a ModelForm using CreateView Class. I have 4 parameters in the URL (start_date, end_date, start_time, end_time) that i'm trying to pass to their relevant fields in the form. I'd really appreciate if anyone can point me in the right direction to figuring out how to solve this! The URL is created with the following function in my html file: window.location.assign("/calendar/create?start_date="+start.format("YYYY-MM-DD")+"&end_date="+end.format("YYYY-MM-DD")+"start_time="+start.format("h:mm A")+"&end_time="+end.format("h:mm A")); This opens from urls.py: url(r'^calendar/create',views.CalendarCreate.as_view(),name='calendar_create'), from views.py: class CalendarCreate(CreateView): model = Event form_class = EventForm from forms.py: class EventForm(ModelForm): class Meta: model = Event So far so good, my event_form.html opens with the form: form and an example URL generated is: http://127.0.0.1:8000/calendar/create?start_date=2017-10-25&end_date=2017-10-25start_time=4:00%20PM&end_time=5:00%20PM This is where I am stuck. From spending a number of days here in stackoverflow, googling, and trying numerous things I believe the solution involves get_form_kwargs or get_context_data or form_valid in views.py but it is possible I have just confused myself trying to work this out. Any help to get me on the right track will be greatly appreciated! -

Summary of data for different users using Serializer in Django
In our app, we have a back-end that runs on the Django Rest Framework. Up to this point what we have been doing is gather data for specific users, which is easy to implement using serializers. @api_view(['GET']) def user_stats(request, format=None): if request.method == 'GET': serializer = StatsSerializer(request.user, context={'request': request}) return Response(serializer.data) In this case, the StatsSerializer is a custom serializers which returns JSON like this: { "id": 2, "first_name": "John", "last_name": "Legend", "profile_photo": "http://localhost:8000/media/profile_photos/john_legend.jpg", "notification_count": 3 } The serializer contains a SerializerMethodField for handling notification_count: def get_notifications(self, obj): return obj.notifications.filter(status=Notification.UNREAD).count() The serializer's model is a simple User Model in this case (request.user). And this goes on for all our end-points (although with different models). However, for a different endpoint we would like to give an overview of data for a list of users and receive a response like this. { "notification_count" : 48, "todo_count" : 72 ... and some more } I think I can get this data in the View with filter and aggregate. However, that is just for one user and thus can I use a User model as the model for the serializer. I would like to do this for a list of users. notificationCount = Notification.objects.filter(user=request.user). … -

I already have a dashboard for those users and he wants the admin forms to be in that dashboard as opposed to the /admin default dashboard. I failed to find such a thing in the documentation, I think. But basically, I want some forms to be avalibale, as they are, in the client dashboard? Is that possible? -
django-ouath-toolkit with social-auth
I'm trying to setup social-auth (python-social-auth) to talk to another Django project with django-oauth-toolkit. I want Django project A to login using OAuth2 from Django project B. Django project A uses social-auth and project B uses django-oauth-toolkit as the OAuth2 provider. Project A can successfully login to other OAuth2 providers such as Google, but I get the following error when trying to login using my custom made backend: AuthStateMissing at /sso/complete/custom-backend/ Session value state missing. This is how the custom backend has been implemented in Project A: class CustomBackend(BaseOAuth2): name = 'custom-backend' EXTRA_DATA = [ ('profile', 'org') ] def authorization_url(self): return "%s/oauth2/authorize" % self.setting("URL") def access_token_url(self): return "%s/oauth2/token" % self.setting("URL") def user_data(self, access_token, *args, **kwargs): resp = requests.get("%s/me/" % self.setting("URL"), headers={ 'Authorization': "Bearer %s" % access_token }) if resp.status_code != 200: raise Exception("Error while getting user details from auth source.") data = resp.json() return { 'username': data['email'], 'first_name': data['first_name'], 'last_name': data['last_name'], 'user_id': data['id'], 'email': data['email'] } There is a setting called SOCIAL_AUTH_CUSTOM_BACKEND_URL which is equal to the base URL of project B (http://localhost:8001 for testing). The URL when Project B redirects to Project A (when the error is raised) is: http://localhost:8000/sso/complete/custom-backend/?redirect_state=6kg4S1eitCMqTTzFGrm9uerG37UNkUPl&code=e64by72AkD2unMVVsGZCz0V2byuUyu&state=6kg4S1eitCMqTTzFGrm9uerG37UNkUPl I thought the issue might be because django-oauth-toolkit doesn't …
