Why is my multiple select form field only submitting one value Django?
Having trouble getting this form to submit/save multiple inputs from my multiple select form field... def StaffHome(request): dates = request.user.availability_set.all() bookings = request.user.booking_set.all() if request.method == 'POST': if 'remove' in request.POST: form = RemoveDate(request.user, request.POST) if form.is_valid(): for d in form.cleaned_data['date']: for i in dates: if d == str(i.dates): i.delete() return redirect('main-home') elif 'add' in request.POST: form = AddDate(request.user, request.POST) if form.is_valid(): for d in form.cleaned_data['date']: Availability.objects.create(user=request.user, dates=d) return redirect('main-home') context = { 'today': datetime.datetime.now().date(), 'bookings': bookings, 'form': AddDate(request.user), 'form2': RemoveDate(request.user), 'dates': dates } return render(request, 'users/staffhome.html', context) I tried using request.POST.getlist('date') but that was throwing a method object not subscriptable error. -

How do I chart Unix dates on a Bokeh chart correctly?
I'm trying to get datetime data on the x-axis of the chart pictured below. Currently the time data is in Unix format from a list: [1586088239188, 1586091716319, 1586095462692, ...] Here's the code in a Django view that I'm outputting to a Django template. I'd like to convert each of the list date elements into a human readable date format. I was able to get as close as: "2020-04-12 03:01:47.708000" but that wouldn't chart on the x-axis. here's the Django def view code with the chart output below: def chart(request): chart_endpoint = "https://api.coingecko.com/api/v3/coins/bitcoin/market_chart?vs_currency=usd&days=7" request_chart_data = requests.get(chart_endpoint) results_chart_data = request_chart_data.json() chart_data = results_chart_data['prices'] #print(chart_data) price = [item[1] for item in chart_data] price_date = [item[0] for item in chart_data] p = figure(title='Line Plot Price and Date', x_axis_label='x', y_axis_label='y') p.line(price_date, price) script, div = components(p) return render(request, 'crypto/chart.html', {'script': script, 'div': div}) Here's my attempt at the date converion and the chart output of that result below.

django: automatic tenant schema recognition in SQLalchemy
In my django app, I am processing data that the user input on the website and I am using SQLalchemist to populate the postgresql database as follow: engine = create_engine('postgresql://myname:mypassword@local:5432/mydb') DB = df555.to_sql('dashboard_items', engine, if_exists='replace') the issue that I encounter is this populates the public schema.

Django ManyToManyField renders as object() instead of description

Django Database Routers not routing to the correct database
I'm writing a dashboard to maintain different apps. Therefor I want to be able to access seperate databases on the server. The final step to get this all working is to setup database routing.

Getting "Authentication credentials were not provided." message when trying to access my ModelViewSet URL
I am creating an application using Django Rest Framework and using Token based authentication. I have a PlaceViewSet class inheriting from ModelViewSet. I want both list and retrieve to work even if there is no token sent by the user whereas create, destroy and update should be allowed only if the user has sent the Token. But I am getting "Authentication credentials were not provided." for requests of all types. I also want to stick to the REST standard so that the list, retrieve, update, create, destroy comes under the same model view set. In case if DRF does not allow any requests without Token if I have set my default authentication as TokenAuthentication then why I am able to access the signin and signup views? -

Django - NoReverseMatch error with two slugs into a template URL

Apache 403 loading video through HTML5 Video player
I have an Django application that streams videos. The application uses drf_firebase_auth. I have tested streaming videos using Postman, the Python requests library, and through the HTML5 video player (using cookie authentication after a sign-in process). When the application is run locally, video streaming works when called by Postman, Python requests library, and the HTML5 player. When the application is run on AWS, video streaming works through Postman and the Python requests library, but it fails with a 403 when trying to stream through the HTML5 video player. During debugging I put print statements in the drf_firebase_auth code. The print statements appear in the apache error log when the video is streamed (i.e. through postman or Python requests), but not when called from the HTML5 player. That seems to indicate that the 403 is happening before getting to Django. Any debugging guidance is appreciated. Thanks. -

Fields with NULL and blank values
I'm writing my first Python web application. My code is difficult because it often needs to treat fields separately if they contain a blank value (object.propery = '') and a Null value (object.property = None). Is there a simple way of dealing with these two values as one? I've noticed some languages have a isNullorEmpty() function. I've also noticed that if a DB field is set to contain numbers then assigning a blank value to the field just makes it Null (convinient :-) -

DRF serializer: method update_or_create is not working as expected
There is a model in which the parameter unique_together class RfiParticipation(models.Model): vendor = models.ForeignKey('Vendors', models.DO_NOTHING, related_name='to_vendor') m = models.ForeignKey('Modules', models.DO_NOTHING, related_name='to_modules') active = models.BooleanField(default=False) user_id = models.IntegerField(null=True, blank=True) rfi = models.ForeignKey('Rfis', related_name='to_rfi', on_delete=models.CASCADE) timestamp = models.DateTimeField(auto_now=True) class Meta: db_table = 'rfi_participation' unique_together = (('vendor', 'm', 'rfi',),) And there is a serializer in which the preservation of an instance in a database is performed by the method update_or_create. class RfiParticipationSerializer(serializers.ModelSerializer): rfi = serializers.PrimaryKeyRelatedField(queryset=Rfis.objects.all(), required=False, allow_null=True) class Meta: model = RfiParticipation fields = ('pk', 'active', 'm', 'rfi', 'vendor', 'timestamp') read_only_fields = ('timestamp', ) def create(self, validated_data): .... .... module, created = RfiParticipation.objects.update_or_create( rfi=validated_data.get('rfi', None), vendor=validated_data.get('vendor', None), m=validated_data.get('m', None), defaults={'active': validated_data.get('active', False)}) return module The problem is that when I try to update an instance, I get an error { "non_field_errors": [ "The fields vendor, m, rfi must make a unique set." ] } But I'm not trying to create a new object with already existing values, but to update it. As I understand it, this error must occur when creating a duplicate and not when updating it.
