Django STATIC_URL on requests
I have this Django project (https://github.com/chakki-works/doccano) that I'm trying to deploy using Apache + mod_wsgi. I set up my .conf file to work as a Daemon proccess where application is served under an alias (/doccano) path: Alias /media/ /var/www/doccano/media/ Alias /static/ /var/www/doccano/app/staticfiles/ WSGIDaemonProcess doccano user=apache group=apache python-home=/var/www/doccano/env WSGIProcessGroup doccano WSGIApplicationGroup %{GLOBAL} WSGIScriptAlias /doccano /var/www/doccano/app/app/wsgi.py The application was doing fine while static files were not being served as I mapped /doccano alias: The Alias /static/ /var/www/doccano/app/staticfiles/ fixed static files problem. But I still want to serve other applications in this server, so mapping /static/ may not be a good idea. So I want to know what is the best approach for this situation. I was trying to add /doccano/ at the beginning of the static requests url setting STATIC_URL=/doccano/static/ but I think this property is not for doing this type of setting. -

Django. Como consultar dos tablas en un mismo formulario?
Estoy haciendo una pequeña app para el control de escrutinio de las elecciones en el cual cargo las mesas donde se van a votas y los partidos politicos participantes. Para cargar la votacion necesito seleccionar la mesa y que me muestre la lista de los partidos politicos con el numero de lista y el nombre del partido. Estoy utilizando Dajngo 2.2 para el desarrollo de la app web. el archivo models.py de la app mesa es: class Mesa(models.Model): num = models.IntegerField(primary_key=True) escuela = models.CharField(max_length=100) el archivo models.py de la app partido es: class Partido(models.Model): lista = models.CharField(max_length=5, primary_key=True) nombre = models.CharField(max_length=100) pres = models.BooleanField() dip = models.BooleanField() Como puedo hacer para que me muestre lo que necesito?

submitting a form with multiple different buttons
I am trying to make a form that has three different submit buttons or inputs. I read that to do that I have to provide a name and a value attribute to the button. I already tried the button tag and input tag. But when I try to submit them and then print the POST request from within Django. nothing is printed. Only the csrf token is included with the POST request. This is the code I am trying. It only works when there is an input tag other than the submit type. but then I can't seperate them because any button will post everything in the form. THanks! <input type="submit" name="first_choice" value="first" class="btn btn-danger" > <input type="submit" name="first_choice" value="second" class="btn btn-info" > <input type="submit" name="first_choice" value="third" class="btn btn-success" > -

Nested get or create functionality - DRF
There have been some posts about nested create functionalities however none seem to have helped me out. You can see here what my json post request looks like: { "games": [ { "company": { "name": "Google", "website": "https://google.com", "trustedpilot": "5" }, "genres": [], "formats": [], "platforms": [], "title": "Call of duty modern warfare", "cover": "https::cover.jpg", "link": "https://google.com", "prev_price": "60.00", "price": "40.00" } ], "company": { "name": "Google", "website": "https://google.com", "trustedpilot": "5" }, "name": "Bundle name", "prev_price": "50.00", "price": "20.00" } The game serializer seems the work fine when creating a single game: class GameSerializer(serializers.HyperlinkedModelSerializer): company = CompanySerializer(many=False) genres = GenreSerializer(many=True) formats = FormatSerializer(many=True) platforms = PlatformSerializer(many=True) class Meta: model = Game fields = '__all__' def create(self, validated_data): # Many to one company_data = validated_data.pop('company') # Many to Many genres_data = validated_data.pop('genres') formats_data = validated_data.pop('formats') platforms_data = validated_data.pop('platforms') # Company company, created = Company.objects.get_or_create(**company_data) # Get the game or created a new one if it doesn't exist yet game, created = Game.objects.get_or_create(**validated_data, company=company) # Platform for platform_data in platforms_data: platform, create = Platform.objects.get_or_create(**platform_data) game.platforms.add(platform) # Format for format_data in formats_data: format, create = Format.objects.get_or_create(**format_data) game.formats.add(format) # Genre for genre_data in genres_data: genre, create = Genre.objects.get_or_create(**genre_data) game.genres.add(genre) return game This is the … -
Passing List as Parameter in Python Requests
I generate a list of IDs, x = [1,2,3] from a set of records pulled from an API request. I then take this list and pass it as a parameter in a second API request which returns a set of records, y = [1,2] which are related to the first by foreign key. The problem I am having is that I need to return or assign a value for each ID in the list, as not every ID in the list has a corresponding record. Therefore, my two lists differ in size when I need them to be 1:1 for when I iterate through the data. How can I return some default value for when the query is false or how can I assign a value for when there is no corresponding record for a given ID? So as, x = [1,2,3] and y = 1,2,3] or x == y. Please let me know if any further information is needed. views.py def do_something(self, request): try: r = requests.get( self.URL + 'domain/endpoint in (' + request + ')', headers=self.Header) r.raise_for_status() except: print(r.text) raise return r.json() y = obj.do_something(x) -
Ubuntu server with Postgres - django.db.utils.OperationalError: fe_sendauth: no password supplied
I am deploying my Django website using Linode (using ubuntu for the server). I manage to create a virtual environment on my Linode server and push my application into it. Now, I want to test if it works, so I run on my server (not local machine): python manage.py runserver 0.0.0.0:8000 However, I get the error: django.db.utils.OperationalError: fe_sendauth: no password supplied On my localmachine, I used postgres: settings.py DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'cocdb', 'USER': 'name', 'PASSWORD': '', # Yes, there is NO password 'HOST': 'localhost', 'PORT': '', } } I think the error is due to the fact that I did not create the postgres database on my Linode server. Is it correct? In order to do so, I plan to follow this guide: https://www.linode.com/docs/databases/postgresql/how-to-install-postgresql-on-ubuntu-16-04/ Access my linux server from Bash and activate my virtual enviroment sudo passwd postgres su - postgres psql -d template1 -c "ALTER USER postgres WITH PASSWORD 'newpassword';" I do not understand what 'template1' refers to createdb cocdb psql cocdb I am not sure if this is correct.

Many to Many in two directions
I have a friend that requested something that I was thinking would be simple and quick. It never turns out that way. Quick disclaimer, model design is a krux of mine.

I am waiting for your kind response, Thanks. -
Django App using Celery Beat + Worker as Windows Service
I created a Django app that runs tasks using Celery as specified in tasks.py. Currently, I'm running it with 2 command prompts windows, one for beat and one for worker with the following commands as per this post: celery -A main worker -l info -P gevent celery -A main beat -l info I read about supervisor but that is for Linux. I have to make this work on a Windows server. I looked at several posts and many of them are old articles with deprecated libraries. This is the most current one I found. I'm following the instructions, but I don't understand where the beat and worker commands go. How does it know to go to my tasks.py and run? I would have commented to the actual post, but I'm not allowed to post because I have less than 50 reputation.

Django crispy-forms how to create a 2 separated column form
I dug into the crispy forms Layout documentation as well as some stackOverflow threads, trying to create a 2 separated column form.

How to render a bound Django model form as HTML-safe?

Django model won't update using .update()
I am trying to update a record in my database using info provided by my website's front-end using Model.objects.update(**kwargs) however on running the code I get the following error: "'Record' with this Id already exists." I would have expected that using the "update" method instead of the "create" method would mean that it shouldn't matter / should be expected that there is already a record with the same ID. def find_patient(request): my_form = ExampleForm() if request.method == "POST": my_form = ExampleForm(request.POST) if my_form.is_valid(): UserInfo.objects.update(**my_form.cleaned_data) else: print(my_form.errors) context = { 'form': my_form, 'data_input': DataInput.objects, 'sections': SECTION_CHOICES } return render(request, 'example.html', context) The resulting error looks tike this: idUser info with this Id already exists.

Displaying Django templates in a VueJS template
I have the following django index page: {% load render_bundle from webpack_loader %} <!DOCTYPE html> <html lang="en"> <head> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/MaterialDesign-Webfont/3.8.95/css/materialdesignicons.css"> <meta charset="UTF-8"> <title>My test</title> </head> <body> <div id="app"> <h1>TEST</h1> </div> {% render_bundle 'main' %} </body> </html> This template is supposed to call my VueJS frontend, so that i can use Vue on my Django templates, this is the Vue template being called: <template> <v-app id="sandbox"> <v-navigation-drawer v-model="primaryDrawer.model" :clipped="primaryDrawer.clipped" :floating="primaryDrawer.floating" :mini-variant="primaryDrawer.mini" :permanent="primaryDrawer.type === 'permanent'" :temporary="primaryDrawer.type === 'temporary'" app overflow ><v-switch v-model="$vuetify.theme.dark" primary label="Dark" ></v-switch></v-navigation-drawer> <v-app-bar :clipped-left="primaryDrawer.clipped" app > <v-app-bar-nav-icon v-if="primaryDrawer.type !== 'permanent'" @click.stop="primaryDrawer.model = !primaryDrawer.model" ></v-app-bar-nav-icon> <v-toolbar-title>TRADIFY</v-toolbar-title> </v-app-bar> </v-app> </template> Which is just a simple Vuetify default template, really similar to this. Until now, it's alright, i can see the page but i don't see the Django part in my template. To debug it, i added that <h1> TEST </h1> to my index page, so when i open http://127.0.0.1:8000/ i should see the Vue template + the Django template. The problem is that i don't see the <h1>. I think that somehow the Vue/Vuetify components are hiding it, because if i remove everything from the Vue part, except <template></template> i will see the <h1>TEST</h1> appearing.

Django Methods in Model Not Updating Properly
