How to deploy Django + Channels + Vuejs + Websocket, with Nginx and Gunicorn?
I'm new to deployment app. I deployed a Django app with Vue as frontend-framework using Nginx and Gunicorn, as there are a lot of online tutorials. For deployment, I simply created configurations files for both Nginx(in path/to/site-enable/) and Gunicorn(a shell script to start the service). I added Django Channels to the app (connected to a localhost redis server), and am able to run it on Django's development server. But then I ran into another issue, how to modify those corresponding files for deployment? Appreciate any help. -

Django post_delete: count all objects which have one matching attribute with deleted object
I have a custom function which is called when deleting an object of the Model Orders, I use post_delete for this. An instance of the model "Orders" always have the ForeignKey "user". When deleting an object of the model "Orders", I want to check whether there are other instances of the model "Orders" with the same "user". def delete_reverse(sender, **kwargs): try: if Orders.objects.filter(user__equal=kwargs['instance'].user).count() == 1: kwargs['instance'].user.delete() else: ... except: pass post_delete.connect(delete_reverse, sender=Orders) Unfortunately, the if condition is not working, i.e. it is not true even when the count of according entries should be 1. Do you see any issue with my count() function? -

Django - Object of type Decimal is not JSON serializable
rows = fetchall() resultList = [] resultModel = [] resultDict = [] for row in rows: resultModel.append(ResultModel(*row)) # Object of type ResultModel is not JSON serializable resultList.append(list(row)) # Rows returned by pyodbc are not JSON serializable resultDict.append(dict(zip(columns, row))) # Object of type Decimal is not JSON serializable I need to get a json version of the data in the view. For this, I am trying to get the JSON dump of the data. Using json.dumps(resultDict) throws the error. The errors trying different results from the model is commented out for reference. The dict(zip()) option is the closest to what I want resultDict gives me a JSON (key, value) pairing that I can use. But it gives me an error on the resulting data that includes 'DecimalField' Is there a way to have decimal places without erroring on the data returned back? It seems that this would be a simple thing Django would support, so I'm not sure if I am missing something! https://github.com/pyeve/eve-sqlalchemy/issues/50 -
How to configure nginx to properly serve mp4 videos to Safari?
I'm attempting to use a video tag to display video in safari. Here is my snippet of html: <video autoplay="" muted="" loop="" preload="auto" poster="http://my.ip.add.ress/static/my_video_image.jpg"> <source src="http://my.ip.add.ress/static/my_video.mp4" type="video/mp4" /> <source src="http://my.ip.add.ress/static/my_video.webm" type="video/webm" /> </video> The static files (css, js, images) are being served up properly. The problem I run into is when safari requests the video, nginx is supposed to return a 206 partial content response. However, it returns a 200 OK with the whole video (I think the whole file is returned). But safari didn't request the whole video, it requested a range of the video using the range header. So this causes the video to not play in Safari. As it sits, my current setup works in Chrome and Firefox. I'm using nginx to serve the video content. I'd like to avoid using a 3rd party server as this is for a small project :). My question is how do I properly setup nginx to serve videos to safari? I know that nginx is ignoring the range header in the request. Is there a way to tell nginx to pay attention to that header? Here is my nginx config in /etc/nginx/sites-available/myproject: server { listen 80; server_name my.ip.add.ress; location = … -
Django Rest Framework failing to patch Serializer.data in view test
I'm unit testing a view and I am attempting to patch the .data property on my serializer but it looks like it behaves differently when the many=True kwarg is passed to the serializer constructor and thus not properly patching.

Troubleshooting HTTP request and JSON message on Django
Okay, so I have been going at this for a while and it doesn't seem like I am getting anywhere. I am running a Django app with Nginx and uwsgi. I have an http.post and I am trying to even read the items which I keep getting errors for. This is what my JS code looks like : $scope.receipt_pay_update = function(items) { response = confirm("Do you want to continue with the changes?"); if(!response){ return; } var data = { 'items': items, 'time_now': moment().format("YYYY-MM-DD") }; items.showmessage = true; console.log(data) $http.post("/foodhub/dashboard/receipt_pay_modal_update", data,{ data: JSON }). success(function(data,status,headers,config){ $scope.alertclass = 'alert-success'; $scope.save_message_farmer = "Succcessfully update payment" console.log("SAVED!") }). error(function(data,status,headers,config){ $scope.alertclass = 'alert-danger'; $scope.save_message_farmer= "Failed to update inventory, please try again" }) } This is what my views.py looks like: @login_required def receipt_pay_modal_update(request): import sys reload(sys) sys.setdefaultencoding('utf8') data = json.loads(request.body)['items'] print data rec = ReceiverActions.objets.get(identifier = data[0]['identifier']) rec['paid_check'] = data[0]['paid_status'] rec['date_paid'] = data[0]['paid_date'] rec.save() return HttpResponse(status=status.HTTP_200_OK) I got an error of unable to decode JSON. So I tried `data = request.body[0] which also didn't work.

Connecting Django to Postgres: django.db.utils.OperationalError: FATAL: database "DATABASENAME" does not exist
I have just started learning Django after I took some tutorials for Python. I am trying to connect my POSTGRES database to the Django project I have just created. However, I am experiencing this problem: django.db.utils.OperationalError: FATAL: database "producthuntdb" does not exist I followed these steps: 1) Opened postgress by clicking its icon 2) Clicked on the database "postgress". The terminal opened and I wrote: CREATE DATABASE producthuntdb; The database has been created because I see it if I open postgress via its icon. 3) Went to my Django project in "settings" and change the SQLITE database to the following: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'producthuntdb', 'USER': 'postgres', 'PASSWORD': 'mypassword', 'HOST': 'localhost', 'PORT': '5432', } } 4) Run the code python3 manage.py migrate However, I am getting the error: django.db.utils.OperationalError: FATAL: database "producthuntdb" does not exist What am I doing wrong? I tried to look other answers to this problem and most of the issues are from misspelling the database name OR not creating it. However, the name of my database is correct and I can see the database producthuntdb if I open postgres. Many thanks for your help. -

Django - Adding fields to a ModelForm that inherits from a parent modelform?
ex. model = Foo Foo.fields(a,b,c,d) FooModelForm1(forms.Modelform): fields = [a, b, c] etc. FooModelForm2(FooModelForm1): fields = [d] As you can see all 4 fields exist in the model but FooModelForm1 is using only 3 fields while i want FooModelForm2 to include field [d] as well as the others. In the documentation it explains you can exclude fields so I know one option would be to flip my forms and include field [d] initially but I was curious if the opposite was possible. I have seen responses that modifies the Meta data from FooModelForm2 but that doesnt seem to be working for me such as: class Meta(FooModelForm1.Meta): fields = ReqLineForm.Meta.fields + ('d',) -
