Django model.objects.all() queryset not displaying content - how to fix?
I'm learning Django and trying to setup some dynamic pages. I've mapped url's to /restaurants and /restaurants/mexican however my html content block is not displaying anything from my queryset. Code below: views.py def restaurantListView(request): template_name = 'restaurants/restaurants_list.html' queryset = Restaurant.objects.all() context = { "objectList": queryset } return render(request, template_name, context) class RestaurantListView(ListView): queryset = Restaurant.objects.all() template_name = 'restaurants/restaurants_list.html' class MexicanRestaurantListView(ListView): queryset = Restaurant.objects.filter(category__iexact='mexican') template_name = 'restaurants/restaurants_list.html' class AsianFusionRestaurantListView(ListView): queryset = Restaurant.objects.filter(category__iexact='asian fusion') template_name = 'restaurants/restaurants_list.html' urls.py from restaurants.views import ( restaurantListView, RestaurantListView, MexicanRestaurantListView, AsianFusionRestaurantListView, ) urlpatterns = [ path('admin/', admin.site.urls), path('', TemplateView.as_view(template_name='home.html')), path('restaurants/', RestaurantListView.as_view()), path('restaurants/mexican/', MexicanRestaurantListView.as_view()), path('restaurants/asian/', AsianFusionRestaurantListView.as_view()), path('about/', TemplateView.as_view(template_name='about.html')), path('contact/', TemplateView.as_view(template_name='contact.html')), ] restaurants_list.html {% extends "base.html" %} {% block head_title %} Restaurants || {{ block.super }} {% endblock %} {% block content %} <h1>Restaurant List</h1> <ul> {% for obj in objectList %} <li>{{ obj.name }} | {{ obj.location }}</li> {% endfor %} </ul> {% endblock content %} I expected the items of Restaurant.objects.all() to be displayed in my content block on restaurants.html, but instead nothing is displaying.

Is there any way to generate a standard response message to the request in drf
I am building an api using Django DRF. The api is working pretty fine. But it is generating different responses, for different kinds of errors. Suppose, if I add a feature of user registration. I am handling some erros in serializers using serializers.ValidationError function. But this is changing the response for different errors. I only want the response in standard manner of {"message": "reason for the error", "error": 1}. I don't want to hard code it. I mean I have used in multiple functionalities, so I have to hard code all the places. Hence, is there any better solution, like adding a function to the serializer and generating the response from that ??? class UserSerializer(serializers.ModelSerializer): confirm_password = serializers.CharField(max_length=50, required=True, validators=[password_check], write_only=True) password = serializers.CharField(max_length=50, required=True, validators=[password_check]) Id = serializers.CharField(max_length=100, required=False, allow_blank=True) user_type = serializers.CharField(max_length=30, required=True, write_only=True) email = serializers.EmailField(required=True) def validate_username(self, username): if User.objects.filter(username=username): raise serializers.ValidationError('Username already chosen!') if len(username) < 8: raise serializers.ValidationError('Username min length is 8') return username def validate_email(self, email): try: validate_email(email) except ValidationError: raise serializers.ValidationError('Enter a valid email') if User.objects.filter(email=email): raise serializers.ValidationError('Email already chosen!') return email def validate(self, attrs): key = 0 try: if models.Profile.objects.filter(userid=attrs['Id']).exists() and attrs['Id'] != '': raise serializers.ValidationError('UserId already chosen') if attrs['Id'] == … -
Play Audio from url on click in background of django template
Problem: once changing this java script snipped to take the element in as a parameter, the audio no longer plays on click I've found several posts regarding this topic but nothing that leads me to a correct answer. I've tried this several ways but haven't had success. Basically, I am trying to play an audio file in the background on the click of an element. The page is definitely pulling down all the audio files according to the network inspection, but the play is not occurring. What am I missing? This is generated by a django template. The template generates hundreds of the following code <div>'s <html> <head> <script> function play(audioid){ var audio = document.getElementById(audioid); audio.play(); } </script> </head> <body> <!-- repeated by template loop --> <span class="text-justify" data-feather="layers"> &nbsp; <i class="fas fa-play-circle" onclick="play(10audio)" title="Play Audio Clip"></i> <audio id="10audio" src="https://d7mj4aqfscim2.cloudfront.net/tts/zs/jiaoling/token/知道"></audio> &nbsp; <a href="#" title="Practice"> <i class="fas fa-dumbbell"></i> </a> &nbsp; <a href="#10" class="text-muted" title="Subject Helper Text"> 知道 </a> </span> </body> </html> -
Django: Replacing piece of url with integer variable
I am trying to replace a url call with a variable as follows: href="{% url 'educators:pay_patient' 9 %}".replace(/9/, x) And the value x is just a primary key of a model, i.e. x=1,2,3, etc.. My issue is that it seems that the number of digits of x and the number it is replacing has to match. For example, x=1 works with 9 but not 90. if x=1, href="{% url 'educators:pay_patient' 90 %}".replace(/90/, x) yields a 404 error with Request URL: http://127.0.0.1:8000/educators/study/pay/90/ How do I make this scheme generalizable for any number of digits of x? -

How to create a form to handle a model OneToOneField to AbstractBaseUser?
After spending 6 months using only django-rest-framework, this last week I needed to use django forms and templates for a simple application (university works XD). So I subclassed the AbstractBaseUser on MyUserModel (almost exactly like the official documentation) to define USERNAME=email, and I created a OneToOneField relation to MyUserModel. I'm not sure how to handle the 2 forms to make it work on creating a user. (I have done the exactly same thing with rest-framework a few months ago, just not sure how to handle it on forms and inside the view) Created MyUser model, e-mail is the USERNAME field. There is first_name, last_name. Company model, with some extra info and a OneToOneField to MyUser. Employees model, with extra info and a OneToOneField to MyUser. From here... How can I proceed to create a Employees user or a Company User, I mean the form view and signup template, If I'm able to create one, the other one will be easy. class MyUser(AbstractBaseUser, PermissionsMixin): email = models.EmailField(verbose_name="E-mail", max_length=255, unique=True) first_name = models.CharField(verbose_name="First Name", max_length=255) last_name = models.CharField(verbose_name="Last Name", max_length=255) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) class Company(models.Model): company = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) register_number = models.BigIntegerField(verbose_name="register") aactivity = models.CharField(verbose_name="Company activity", max_length=255) class Employees(models.Model): … -
How to use FileField with digitalocean storage?
I'm trying to setup my django app to use digitalocean storage. I'm currently uploading files simply through the admin panel. I've done the following config in my settings.py: AWS_DEFAULT_ACL = None AWS_ACCESS_KEY_ID = 'XXX' AWS_SECRET_ACCESS_KEY = 'xxx' AWS_STORAGE_BUCKET_NAME = 'tickets' AWS_S3_ENDPOINT_URL = 'xxx' AWS_S3_OBJECT_PARAMETERS = { 'CacheControl': 'max-age=86400', } AWS_LOCATION = 'ticketfiles' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'ticketfulfillment/static'), ] STATIC_URL = 'https://%s/%s/' % (AWS_S3_ENDPOINT_URL, AWS_LOCATION) STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' When I upload a file, I don't get any errors, but when I check my storage bucket in digitalocean I don't see the files there, and I cannot access them on my app either. Can anyone give me guidance on uploading files to digitalocean storage through a FileField in django? -
