Django ElasticSearch Rest Framework Suggesting Results duplicate title
In my database, there are lots of duplicate titles but their id is not duplicate and other properties are not duplicated. only title duplicate. I have implemented API for auto suggest but it is not currently returning duplicate results. coz, in database, most of the product are duplicate title. the duplicate title is normal but it should not return in API response for auto suggest, this is what I tried: from django_elasticsearch_dsl_drf.filter_backends import ( SuggesterFilterBackend ) from django_elasticsearch_dsl_drf.viewsets import DocumentViewSet from django_elasticsearch_dsl_drf.constants import ( SUGGESTER_COMPLETION, ) class SuggestionsAPIView(DocumentViewSet): document = ProductDocument serializer_class = ProdcutTitleSerializer filter_backends = [ SuggesterFilterBackend, ] suggester_fields = { 'title': { 'field': 'title', 'suggesters': [ SUGGESTER_COMPLETION, ], 'options': { 'size': 20, 'skip_duplicates':True, }, }, } Anyone know about this? How can I get rid of such a duplicate results? -
How to create custom permissions for django admin site
By default when I create a model Django gives permissions like add/change/delete/view If I give any of the above permission to a specific user then that user can view all the objects from that model. But I want to show them only objects linked with foreign keys. Let's Say, I have a Book model class Book(models.Model): title = models.CharField(max_length=100) author = models.ForeignKey( User, on_delete=models.CASCADE ) If I want to give authors permission, they can only view their linked books from the Django admin. How can I do that? -

Django Model Instance as Template for Another Model that is populated by Models
I'm trying to create the create a workout tracking application where a user can: Create an instance of an ExerciseTemplate model from a list of available Exercise models. I've created these as models so that the user can create custom Exercises in the future. There is also an ExerciseInstance which is to be used to track and modify the ExerciseTemplate created by the user, or someone else. I'm stripping the models of several unimportant fields for simplicity, but each contains the following: class Exercise(models.Model): # Basic Variables name = models.CharField(max_length=128) description = models.TextField(null=True, blank=True) def __str__(self): return self.name class ExerciseTemplate(models.Model): # Foreign Models workout = models.ForeignKey( 'Workout', on_delete=models.SET_NULL, null=True, blank=True ) exercise = models.ForeignKey( Exercise, on_delete=models.SET_NULL, null=True, blank=True ) recommended_sets = models.PositiveIntegerField(null=True, blank=True) class ExerciseInstance(models.Model): """ Foreign Models """ exercise_template = models.ForeignKey( ExerciseTemplate, on_delete=models.SET_NULL, null=True, blank=True ) workout = models.ForeignKey( 'Workout', on_delete=models.SET_NULL, null=True, blank=True ) """ Fields """ weight = models.PositiveIntegerField(null=True, blank=True) reps = models.PositiveIntegerField(null=True, blank=True) Create a WorkoutInstance from a WorkoutTemplate. The WorkoutTemplate is made up of ExerciseTemplates. But the WorkoutInstance should be able to take the WorkoutTemplate and populate it with ExerciseInstances based on the ExerciseTemplates in the WorkoutTemplate. Here are the models that I have so far: … -
Exposing React App with Local MySQL Database to Internet Using Ngrok
I am very new to ngrok, so please bear with me. I have a very simple React test app that is using Django as a server and local MySQL database. Django pulls/inserts some info from the local database and sends to the frontend. Everything works well. What I'm trying to do is expose this local app to public Internet. I have successfully installed and configured Ngrok, established a tunnel and was able to view the app on a different computer through the address generated by Ngrok. The problem is, I was able to see only the UI that is not related to the database. All data that React pulls from the local database, was not visible when I used a different computer. My question is, is there a way to use the same app through Ngrok and get the same data from the local MySQL database that I see when I just run the app locally? I know that I can create another tunnel that exposes the port MySQL or Django are running on (3306 and 8000 respectively) but if I do this, how would I access the data through Ngrok? Would I need to change anything in React code? … -
Django - Passing an extra argument from template to urls.py to class-based view
Basically, I would like to transition from a page showing a table (which is the result of a user query), to a page where the user can edit an entry in the table (this page is built using UpdateView), and then straight back to the previous page but this time showing the table with the new update reflected. There are other posts on similar situations but none seem to show how to implement this using a class-based view, so any advice here would be most appreciated. So far I have come up with the approach below. Here, I am trying to pass a parameter holding the URL of the table page, from the template for the table page to urls.py and then onto the view. However, I don't think I am using the correct syntax in urls.py as the value of the previous_url parameter in the view is simply "previous_url". Link in the template for the table page <a href="{% url 'entry_detail' item.pk %}?previous_url={{ request.get_full_path|urlencode }}">Edit</a> URL path('entry/<int:pk>/edit/', EntryUpdateView.as_view(previous_url="previous_url"), name='entry_update'), View class EntryUpdateView(LoginRequiredMixin, UpdateView): model = Entry template_name = 'entry_update.html' fields = ('source', 'target', 'glossary', 'notes') previous_url = "" def form_valid(self, form): obj = form.save(commit=False) obj.updated_by = self.request.user obj.save() return … -

Python virtual environment does not have a scripts folder and cannot be activate
I am new at programming and I want to work with Python and meanwhile with the Django Framework. For installing a venv I use "python3 -m venv ./venv/drf" and insert this in a terminal in VS code. I found this on my research about my problem. But when I installed the venv there is not a script folder in the venv folder. For activating my venv I tried "source .venv/drf/bin/activate" but this is neither working. I am working on a mac and I installed Python previously. I even installed Django on VS code. What can I do to implement the scripts folder and activate my venv? -
How Can I Verify that Django @cached_property is Cached?
In the below example, I have questions. Example from django.utils.functional import cached_property class Product(models.Model): class ProductType(models.TextChoices): PRODUCT = 'PRODUCT', _('Product') LISTING = 'LISTING', _('Listing') my_model = models.ForeignKey(MyModel, on_delete=models.CASCADE, related_name='products') product_type = models.CharField(max_length=7, choices=ProductType.choices) class MyModel(models.Model): ... @cached_property def listing(self): return self.products.get(product_type=Product.ProductType.LISTING) Questions Is the listing property being cached on the MyModel object? I ask because it's accessing .get() of a queryset which has greater implications. Ex: instance = MyModel() instance.listing # hits db instance.listing # gets from cache? How can I set up a scenario to inspect and verify that caching of instance.listing is in-fact happening? I read to look in the __dict__ method of instance.listing.__dict__ but I don't notice anything specific. -
expanding dict model field in django
I need a way to be able to enter an unspecified number of arbitrary, integer values with an auto-incrementing key into a dictionary in a django model. It would need to look, or at least function, like this: { "1":6, "2":10, "3":0, ... "n":42 } I'm hoping there will be a simple solution like: class Foo(models.Model): title = models.CharField(max_length=100) dictOfInts = { models.AutoField(): models.IntegerField, models.AutoField(): models.IntegerField, models.AutoField(): models.IntegerField ... # it would start with just one and automatically add more k-v pairs as nessary } #other fields ect def __str__(self): return self.title Unfortunately, I know that doesn't work and wouldn't function how the comment suggests, but it would need to act like that for the end-user. I've looked through the docs and the only workaround I found there was using models.JSONField(), but that requires you to type out the dict yourself, which is not ideal. Another possible way that I found would be to separate the dict and the k-v pairs, linking them with a foreign key, but I couldn't quite figure out how to integrate it and it seemed very messy even if I could. If you need any more info, just let me know. Any help is much … -
Unable to push json file to Heroku for database data dump
I'm working on a school project, I have no experience with any of this and am having a hard time with this last step of setting up a website. For some background, the front end is coded in Next.js, backend is Python utilizing Django, and I have deployed the backend to Heroku (I have the app built and the database (postgreSQL) setup). I have done all of this following a tutorial that I found on Udemy which is only about a year old. I have run into some issues along the way but was able to figure them out after some trial and error, but this one is really giving me a hard time. So, in the tutorial he does a datadump and puts it into a file named "dump.json", then he runs the following command: heroku run python manage.py loaddata dump.json, which dumps the data into Heroku and the database populates and his Heroku app is up and running (it's connected to the Django rest framework, which is coded in the front end). Well, here is what I get when I run the command, I have to specify the path to manage.py otherwise it won't work, fyi... I have … -

Increasing the searching speed of Django set.all()
I am using Django to filter through a MongoDB full of data. Right now I have code that is working and have found where my slowdown is at... def does_this_property_apply(prop, app, dev, event): for platform_device in prop.platformdevice_set.all(): for event in platform_device.applicable_events.all(): if event.name == event: for app in platform_device.applicable_app.all(): if app.name == app: for device in platform_device.applicable_device.all(): if device.name == dev: print("This property applies") Basically I have 400+ properties that have a bunch of metadata. Inside of each property is a platform_device object (model) that contains information such as app, dev, and event. Think of it as this property only applies to certain applications, on certain devices, on certain user actions (events). Each property can have multiple of these. I am new to Django and trying to find out how I could quickly search all platform_device in the database and find if this property (prop) is applicable to my event, device, and application. class PlatformDevice(models.Model): _id = models.UUIDField(unique=True, primary_key=True,default=uuid.uuid4, editable=False) name = 'Property Specifics' property_field = models.ForeignKey('Property', on_delete=models.CASCADE) applicable_app = models.ArrayReferenceField(to=Platform, on_delete=models.CASCADE, blank=True) applicable_device = models.ArrayReferenceField(to=Device, on_delete=models.CASCADE, blank=True) applicable_events = models.ArrayReferenceField(to=Event, on_delete=models.CASCADE, blank=True) event_group = models.ArrayReferenceField(to=EventGroups, on_delete=models.CASCADE, blank=True) def __str__(self): return self.name -
