How to redirect to a new template using already rendered data in django
I do have a model called Pollers which consists of individual questions asked by users. One template renders an overview of the latest questions asked. Now I would like to redirect the user to a new template for a specific question upon click of its container. Now my understanding is that I would define a url that contains a <slug:slug> field to catch some data from the first template to query the correct item from the database to render the new template. But how do I grab the data (in my case it would probably be the UUID?) pass the data to the url and use it in a new view to query the database for this certain question? Model class Questions(models.Model): # Assign unique ID to each poller poller_id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) # Assign timestamp of creation created_at = models.DateTimeField(auto_now_add=True) # Assign the user who created the poller by her ID via user session created_by = models.CharField(max_length=100) # Poller Text poller_text = models.CharField(max_length=250) # Choices given by user poller_choice_one = models.CharField(max_length=30) poller_choice_two = models.CharField(max_length=30) [...] View def pollboard(request): # Query Pollers questions_queryset = Questions.objects.all() # Convert to list qs_list = list(questions_queryset) # Shuffle the list shuffle(qs_list) # Create … -
What is an efficient way of inserting hundreds of records into an SQLite table using Django?
I have a CSV file with hundreds of data, I want to insert everything into my SQLite DB in my Django app. Inputting each value one by one will be a complete waste of time. What is a more efficient way to approach this? -
Best practice for sending POST request from client side to Django models?
Relatively new to Django so apologies if I'm not getting all the wording here right. I'm sending data from my client side (React) to my models through a POST request. Django can handle this either through its class-based views, something like this: views.py class ListCreateView(ListCreateAPIView): queryset = Users.objects.all() serializer_class = UsersSerializer serializers.py class UsersSerializer(serializers.ModelSerializer): class Meta: model = Users fields = "__all__" urls.py urlpatterns = [ path('', ListCreateView.as_view()), ] or through something like this: views.py def create_user(request): if request.method == 'POST': response=json.loads(request.body) user_db = Users() user_db.user = response['user'] user_db.save() return(HttpResponse(200)) What's better? I'm using something similar to both of these, and they both work. What should I be thinking about? Thanks. -
PostgreSQL error "unable to connect to server

Django adding words to image url
I want to load an image on my template using: <img src="{{ item.pic }}"> It works fine sometimes but once I start doing it from a view it adds the path of that view to my image src automatically causing the image to fail to load. I want it to be src="images/item.jpg" for example, but because of different views it may end up as "view1/images/item.jpg" or "anotherview/images/item.jpg" causing Django to be unable to find the image. Is there a way to code it so that view names won't be added to the src? -
Django filter by looping through each day of a date range
I have a model called Orders which is for an e-commerce web-app and I'd like to know how many orders was made from each day in the past year. so I filtered the Orders as follows: product_orders = Order.objects.filter( ordered=True, variant__product=self, date__range=[(timezone.now() - timedelta(weeks=52)), timezone.now()]) I'd like to loop through each day from this time range and get the number of orders from each day, the result should look something like this: [ { date: "2021-06-21", quantity: 6 }, { date: "2021-06-22", quantity: 0 } ] where the quantity is Order.objects.filter(...).count() -
bulk create for models with foreign key
I have these two models: class Item(models.Model): item_id = models.CharField(max_length=10, primary_key=True) item_name = models.CharField(max_length=100) description = models.CharField(max_length=500) slug = models.CharField(max_length=200) price = models.FloatField() def __str__(self): return self.item_name class Image(models.Model): item = models.ForeignKey(Item, on_delete=models.CASCADE) image_url = models.CharField(max_length=200) I have a lot of items, and each Item has some images assigned to it. To add items in the database, I do it through a bulk create: it = (Item( item_id = item['id'], item_name= item['title'], description = item['description'], slug = item['slug'], price = item['price']['amount'] ) for item in items ) while True: batch = list(islice(it, batch_size)) if not batch: break Item.objects.bulk_create(batch, batch_size) This works perfectly fine, ok. But I want to do the same with the images, since I have too many images to do it individually. For now I do it like this: for item in items: for image in item['images']: Item.objects.get(item_id = item['id']).image_set.create(image_url = image['urls']['big']) But this is too slow in uplaoding all the Images (it may take 30 minutes), so I want to upload in bulk like I do it with Item, but since Image model has Item as a foreign key, I cannot do it the same way. How can I upload Images in a more efficient manner? I … -
Where to store media file of Django on production?
So I am learning Django. And I have made some websites with it. Now I am hosting those to Heroku. I am using free Dyno on Heroku. Also, I am using supabase.io database instead of Heroku's because supabase gives more space for the database on the free tier. Now the problem I am facing is with the media files. I can not access them on Heroku since I don't have any place to store them. I have seen some addons on Heroku for the file storage but to use those I need to provide my credit card information, which I do not have. But I have seen an object storage option on supabase.io. It gives 1 GB free storage which is more than enough for me now. But I don't know how can I use it with my Django application. That is why I am looking for help. Also if there are any free alternatives to store my media file without credit card information, please feel free to guide me. Since I do not own any card. -
How to fix "Failed to restart gunicorn.service: Unit gunicorn.socket not found." error?
I'm trying to deploy a django application to a DigitalOcean droplet. I created a systemd service to start gunicorn on boot. Here is my config file: (/etc/systemd/system/gunicorn.service) [Unit] Description=gunicorn daemon Requires=gunicorn.socket After=network.target [Service] User=root Group=www-data Environment="DJANGO_SETTINGS_MODULE=core.settings.production" WorkingDirectory=/home/myproject-api/src ExecStart=/home/myproject-api/env/bin/gunicorn --access-logfile - --workers 3 --bind unix:/run/gunicorn.sock core.wsgi:application [Install] WantedBy=multi-user.target When I run "ExecStart" line on directly on terminal, it works. But I cant start the gunicorn service. I get this error when I try to start gunicorn: Failed to start gunicorn.service: Unit gunicorn.socket not found. I checked the gunicorn executable, it exists: test -f /home/myproject-api/env/bin/gunicorn && echo "Gunicorn exists." I'm able to run server with gunicorn --bind 0.0.0.0:8000 core.wsgicommand. When I run like this, i can access the server using the server's IP address. Normally, the socket file should been created when I start the server. Also I tried to create the socket file with "touch /run/gunicorn.sock" but it didn't work. I double-checked file and directory names. No mistake. How can I solve this problem? -

Postgres: sanitize string before searchin for it
I have a website which uses Postgres as a database. I now want users to be able to search the database for strings and am using pg_trgm for that. I can imagine that it is very dangerous to just search the database for the plain user input, as it could be malicious. So my question is: what security measures do I have to take in order to search for a string in Postgres, which could potentially contain malicious code? Are there for example certain characters which should be escaped? Thanks in advance, Kingrimursel -
Decoupling auth/auth from Django applications
I author a couple of Django applications that I deploy behind an auth/auth system. Currently, my apps' class-based views are hard-coded with my particular auth requirements, by using DRF's authentication_classes and permission_classes and Django's permission_required decorator (and friends). The problem I have is that I can't really figure out any way to configure these on a project level. For example, while testing, I don't want to have to deal with my auth system--creating test users, logging in, etc. I just want to test my app. But even though I have a separate Django environment for production and development, there's no elegant way for me to, in my dev environment's settings.py, say (for example) MYAPP_AUTH_MODEL=None and in my prod environment, say something like MYAPP_AUTH_MODEL=permission_required('myperm_create'). As another example, how could I give consumers of my app complete control over how they secure their deployment, including allowing them to choose not to secure it at all? How does one write a Django app that can be secured with auth/auth, without writing anything into the app that places restrictions on how it's secured in any given deployment? -

Translating django tables2 template column header
Hi i'm working with django-tables2 and I have a table where I need to translate the headers of each column. class ModelTable(tables.Table): name = tables.columns.Column() edit = tables.TemplateColumn('<a href='{% url "edit_my_model_instance" record.id %}'>Edit</a>', verbose_name=u'Edit', ) delete = tables.TemplateColumn('<a href='{% url "del_my_model_instance" record.id %}'>Delete</a>', verbose_name=u'Delete', ) class Meta: model = models.Model The above code without translations work fine, but when I add the gettext for translate like this : delete = tables.TemplateColumn('<a href='{% url "del_my_model_instance" record.id %}'>Delete</a>', verbose_name=_(u'Delete'), ) Where I added gettext as _ : verbose_name=_(u'Delete') I receive the following error TypeError: 'TemplateColumn' object is not callable The thing is if I use tables.Column it works fine with translation, so the problem is only when I user TemplateColumn. If you can guide me through this I'd appreciate it, thanks. -
