Django pagination with no primary key
I have this function in views.py that will display all categories in a research management system following several tutorials: def CategoryView(request): cat_menu=Category.objects.all(); return render(request, 'Category.html',{'cat_menu':cat_menu}) When a user clicks on a category, they will get all the research papers that are under this category Views.py def ResearchCategoryView(request,cats): category_research=ResearchesList.objects.filter(research_category=cats.replace('_',' ')) return render(request,'Researches-Guest.html',{'cats':cats.title().replace('_',' '),'category_research':category_research,}) I would like to add a paginator to ResearchCategoryView, except I can't link to the same url as the category is not a primary key in the research table. Is there a way to do this without having to rewrite ResearchCategoryView? urls.py path('',views.GuestHome,name="GuestHome"), path('FeedBackForm',views.Form2,name="FeedBackForm"), path('FeedBackRecieved',views.ThankYou,name="ThankYou"), path('Category/',CategoryView,name='Categorys'), path('Category/<str:cats>',ResearchCategoryView,name='researchcategory'), path('Category/cats',ResearchCategoryView,name='researchcategory2'), path('Research/<int:pk>',AbstractView.as_view(),name='abstract'), path('search_research', views.search_research, name='search_research'), ** models.py inspected from mySQL** class ResearchesList(models.Model): research_id = models.AutoField(primary_key=True) title = models.TextField() auther = models.TextField() auther1 = models.TextField(blank=True, null=True) auther2 = models.TextField(blank=True, null=True) auther3 = models.TextField(blank=True, null=True) auther4 = models.TextField(blank=True, null=True) auther5 = models.TextField(blank=True, null=True) auther6 = models.TextField(blank=True, null=True) abstract = models.TextField() publish_date = models.DateField() start_date = models.DateField() finish_date = models.DateField() research_url = models.TextField() journal_name = models.CharField(max_length=100) research_category = models.CharField(max_length=70) data_type = models.CharField(max_length=45, blank=True, null=True) data_source = models.TextField(blank=True, null=True) geo_area = models.CharField(max_length=45, blank=True, null=True) is_collected_via_socialmedia = models.CharField(max_length=45, blank=True, null=True) collecation_start_date = models.DateField(blank=True, null=True) finishing_colleaction_date = models.DateField(blank=True, null=True) date_of_the_data = models.DateField(blank=True, null=True) sample_size = models.IntegerField(blank=True, null=True) … -

Can't connect to Websocket on Django with Heroku
I'm trying to deploy my Django app to Heroku. The thing is, when I try to test the Websocket I implemented, it doesn't connect. (Btw, I'm using the Postgres service that Heroku gives to storage my data). This is what I get when I try to test it: It's from a website called https://hoppscotch.io/realtime/ Here's the config of my Procfile: web: gunicorn kuropoly.wsgi. The routing.py part is configured like this: from django.conf.urls import url from apps.websocket.consumers import KuropolyConsumer websocket_urlpatterns = [ url(r'^wss/play/(?P<idRoom>\w+)/$', KuropolyConsumer.as_asgi()), ] And, as it says there on the code, I'm using ASGI, here's the config for that: asgi.py import os from django.core.asgi import get_asgi_application from channels.auth import AuthMiddlewareStack from channels.routing import ProtocolTypeRouter, URLRouter import apps.websocket.routing os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'kuropoly.settings') # application = get_asgi_application() application = ProtocolTypeRouter({ "http": get_asgi_application(), "websocket": AuthMiddlewareStack( URLRouter( apps.websocket.routing.websocket_urlpatterns ) ), }) On my settings.py I have this: ASGI_APPLICATION = "kuropoly.asgi.application" CHANNEL_LAYERS = { 'default': { ## Via In-memory channel layer "BACKEND": "channels.layers.InMemoryChannelLayer" }, } # Activate Django-Heroku. import django_heroku django_heroku.settings(locals()) import dj_database_url DATABASES['default'] = dj_database_url.config(conn_max_age=600, ssl_require=True) I've tried changing my Procfile but that didn't work, I don't know if it's because of the fact that I'm using gunicorn (and I used that following the Heroku … -

django.db.utils.OperationalError: fe_sendauth: no password supplied when migrating django app
I'm a beginner with Django working on an open source project, which has been very challenging since it only gives build instructions for Mac, and not Linux. So, on my Ubuntu server, I've managed to install all the packages and fix a few initial bugs, but now, when I do python manage.py migrate, I'm stuck with this error: django.db.utils.OperationalError: fe_sendauth: no password supplied I'm totally stuck here: I'm having a tough time understanding the error message, and other solutions aren't much help. Other solutions indicate that you have to change the DATABASES setting in the settings.py, but the setting has no PASSWORD attribute and it's only linked to sqlite: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), } } DATABASES['default'] = dj_database_url.config() The error doesn't trace back to any specific lines of code so I'm guessing its more related to psycopg2 or django than the code itself, but I'm not sure how to go about fixing it. I'm using Python 2.7.17 and Ubuntu 18.04.5. Here's the full error message: Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 364, in execute_from_command_line utility.execute() File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 356, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/usr/local/lib/python2.7/dist-packages/django/core/management/base.py", line … -

Is there a way to maintain structure of nested serializer output across different levels?
I've included a simple example below which will help illustrate the question I'm trying to ask. May have typos/errors since I'm not running the code. Suppose we have models Singer, Album and Track. A singer can have multiple albums and an album multiple tracks (just a series of one to many relationships). ### Models ### class Singer(Model): singer_name = models.CharField(max_length=20) class Album(Model): singer_id = models.ForeignKey(Singer) album_name = models.CharField(max_length=20) class Track(Model): album_id = models.ForeignKey(Album) track_name = models.ChairField(max_length=20) ### Serializers ### class TrackSerializer(ModelSerializer): class Meta: model = Track fields = ['track_name'] class AlbumSerializer(ModelSerializer): tracks = TrackSerializer(read_only=True,many=True) class Meta: model = Singer fields = ['album_name','tracks'] class SingerSerializer(ModelSerializer): albums = AlbumSerializer(read_only=True,many=True) class Meta: model = Singer fields = ['singer_name','albums'] If we have a simple view that requires a singer's name for input, the Singer Serializer would output the following. ### SingerSerializer Output ### { "singer_name":"Singer A", "albums": [ { "album_name":"Album 1", "tracks": [ {"track_name":"Track 1"}, {"track_name":"Track 2"} ] }, { "album_name":"Album 2", "tracks": [ {"track_name":"Track 3"}, {"track_name":"Track 4"} ] } ] } Now suppose in a separate view, I would like people to be able to input an album name (let's say Album 1 in this case).
