Django - Admin user only able to create data. FOREIGN KEY constraint failed for normal users
I'm creating a simple CRUD application to brush up on my Django skills (it's been a long time!) but I'm getting the below errors when I have a non-admin users create anything, either via the frontend or the sites backend: FOREIGN KEY constraint failed I'm also getting this error when I'm logged in as the admin user and try to update the user field in the Django Admin panel. The functionality itself works, as I can create activities through the frontend and backend when I'm logged in as the superuser. I've also tried deleting migrations etc.. but there doesn't seem to be any resolutions. The site itself uses Django's allauth models, but with custom models to fit the general purpose, but I'm still using the AllAuth user model as my foreign key, as the other model is a UserProfile: Below is my models.py file for the activities: class Activity(models.Model): class Meta: verbose_name_plural = 'Activities' activity_id = models.AutoField(primary_key=True) host = models.ForeignKey(User, on_delete=models.CASCADE, related_name="activity") name = models.CharField(max_length=254, null=False, blank=False) date = models.DateField() start_time =models.TimeField() end_time = models.TimeField() location = models.CharField(max_length=40, null=False, blank=False) description = models.CharField(max_length=140, null=False, blank=False) available = models.BooleanField(default=True) def __str__(self): return str(self.activity_id) With the view: def create_activity(request): if request.method == … -
Offloading extensive calculations in save method of Django custom FileField
I'm building a gallery webapp based on Django (4.1.1) and Vue. I want to also upload and display videos (not only images). For supporting formats, that don't work in a video html tag, I'm converting these formats to mp4 via pyffmpeg. For that I created a custom field for my model based on FileField. In it's save method I take the files content, convert it and save the result. This is called by the serializer through a corresponding ViewSet. This works, but the video conversion takes way too long, so that the webrequest from my Vue app (executed with axios) is running into a timeout. It is clear, that I need to offload the conversion somehow, return a corresponding response directly and save the data in the database as soon as the conversion is finished. Is this even possible? Or do I need to write a custom view apart from the ViewSet to do the calculation? Can you give me a hint on how to offload that calcuation? I only have rudimentary knowledge about things like asyncio. TL;DR: How to do extensive calculations asychronous on file data before saving them to a model with FileField and returning a response before … -
Django admin displays datetime fields inconsistently in Django admin view and in rendered tables
I have a model that is an activity object to save api JSON data for database queries. The api sends a start date (UTC) and a local start date. I am experiencing an inconsistent treatment of the UTC time value and the local time value. Model class ActivityObject(models.Model): name = models.CharField(max_length=50) distance = models.DecimalField(max_digits=8, decimal_places=2) moving_time = models.DurationField() elapsed_time = models.DurationField() total_elevation_gain = models.DecimalField(max_digits=5, decimal_places=2) type = models.CharField(max_length=15) start_date = models.DateTimeField() start_date_local = models.DateTimeField() average_speed = models.DecimalField(max_digits=5, decimal_places=2, blank=True, null=True) max_speed = models.DecimalField(max_digits=5, decimal_places=2, blank=True, null=True) average_cadence = models.DecimalField(max_digits=6, decimal_places=2, blank=True, null=True) has_heartrate = models.BooleanField(blank=True, null=True) average_heartrate = models.DecimalField(max_digits=6, decimal_places=2, blank=True, null=True) max_heartrate = models.DecimalField(max_digits=6, decimal_places=2, blank=True, null=True) activity_logged_time = models.DateTimeField(default=timezone.now, blank=True) def __str__(self): return 'id %s----name %s----start date %s----start date local %s----logged date %s' % (self.id, self.name, self.start_date, self.start_date_local, self.activity_logged_time) The unexpected behavior is that the field values inside the object are reversed. I get the values from API and convert the JSON to datetime objects. start_date = a_row['start_date'] start_date_pretty = convert_json_to_datetime(start_date) print('start date ', start_date_pretty) start_date_local = a_row['start_date_local'] start_date_local_pretty = convert_json_to_datetime(start_date_local) print('start date local ', start_date_local_pretty) Relevant JSON key and values: "start_date": "2022-11-04T21:01:20Z", "start_date_local": "2022-11-05T08:01:20Z", I have USE_TZ = True -
Django migrations dont work. Have to delete the db and start fresh eveery time
I have a django project which works fine. However, each time there is a change in my models (when I add attributes to my model), the migrations stop working. There is usually some sort of error or the migrations will not execute. The only way for me to make the migrations to work is to drop the database and start fresh. This is a very strange behavior and cannot work in a live/production environment. I recently had to delete the db in the production environment and it was very messy. Is there a way to fix this ? Isnt this strange that Django makes it harder to work with migrations when it claims that migrations make everything easy. Am I doing something wrong ? I dont know where to start from. -
How can I create an API index using multiple DRF routers?
I'm trying to build an API using DRF with the following structure (example): api/ ├── v1/ │ ├── foo/ │ │ ├── bar/ │ │ │ └── urls.py # There's one `rest_framework.routers.DefaultRouter` here │ │ ├── bar2/ │ │ │ └── urls.py # There's one `rest_framework.routers.DefaultRouter` here │ │ ├── __init__.py │ │ └── urls.py │ ├── foo2/ │ │ ├── bar3/ │ │ │ └── urls.py # There's one `rest_framework.routers.DefaultRouter` here │ │ ├── bar4/ │ │ │ └── urls.py # There's one `rest_framework.routers.DefaultRouter` here │ │ ├── __init__.py │ │ └── urls.py │ ├── __init__.py │ └── urls.py ├── __init__.py └── urls.py Intuitively, my endpoints would be https://api.example.com/v1/foo/bar/... https://api.example.com/v1/foo/bar2/... https://api.example.com/v1/foo2/bar3/... https://api.example.com/v1/foo2/bar4/... But I want that Api Root web page to be available from the https://api.example.com/v1 level. For example, when I ran curl https://api.example.com/v1 it would show me {"foo":"https://api.example.com/v1/foo/","foo2":"https://api.example.com/v1/foo2/"} and so on. That being said, I guess that the way to do it was to somehow "merge" those DefaultRouters. I'm aware that I could just router.registry.extend(some_other_router.registry), but that would make it all be at the same level and I explicitly needed it to be multi-level, as shown above. -
Having Trouble Adding Pagination In Class Views ( get_queryset )
Good day everyone, I'm trying to build a product category with pagination using class view (get_queryset). I followed a tutorial that did not actually cover this part that has get_queryset.

How to access contents of a SimpleArrayField in Python Django
I am currently working with a form class in Django. I need to be able to access data contained in a SimpleArrayField. class SignUps(forms.Form) people = SimpleArrayField(forms.EmailField(), label="name") Let's say a user fills out the form with the names "John Smith," "Jane Smith", "Mike Smith". I need to be able to access the names. I've tried various methods such as print(people["name"]) or print(people[0]) But I keep getting the error TypeError: 'SimpleArrayField' object is not subscriptable. I've tried to figure out to access fields from a SimpleArrayObject, but I don't see any examples in documentation. How would I go about getting the names from the people object? Is that even possible to do? -

Add Javascript string variable INSIDE a django template variable
I have a chart that is populated by django template variables. I have an update chart function that updates the data after certain buttons are clicked. Instead of writing the same js function 7x, can I update the javascript function to call the correct data within a Django template variable? Basically, the btn_id will either be A, B, C, D, E, or F and I want the django template variable to display the correct data based on the btn_id value. var results = {{ all_test_results.A.curve_series.curve_series }}.map(function(val, i) { return val === 'None' ? null : val; }); becomes const btn_id = this.id.slice(-1); # A, B, C, D, etc var results = {{ all_test_results.{{ btn_id }}.curve_series.curve_series }}.map(function(val, i) { return val === 'None' ? null : val; }); I am sure there is a simple way to inject a js string into a Django template variable, right? -

How to create multiple filters in Django?
I want to create multiple filters in Django. The screen shot below explains it. The user may opt not to select some criteria. If the user does not select Available from, Available till and Advance then I will get the value as None in views.py. If he does not select Category or Capacity then I will get an empty list otherwise I will get a list of Category or Capacity. The problem arises when there is None or empty list.

Django Reversion - Viewing incompatible version data
Is there a way to view incompatible version data using Django-Reversion or after making a change to the model? I understand I wouldn't be able to revert or reinstate a previous version before the model change, but is there a way to simply view the data? Here's the model before the change: class Product(models.Model): product_code = models.CharField(max_length=120, blank=True, null=True) #max_length=required related_category = models.ForeignKey(Category, on_delete=models.DO_NOTHING, blank = True, null=True) Then I added a 'discount' field: class Product(models.Model): product_code = models.CharField(max_length=120, blank=True, null=True) #max_length=required related_category = models.ForeignKey(Category, on_delete=models.DO_NOTHING, blank = True, null=True) discount = models.BooleanField() when I try to access previous versions, I see an error - "Could not save XXXXX version - missing dependency." I tried accessing previous versions via admin site and also by calling Version.objects.get_for_model(Product). I was expecting to be able to view the historical versions, but instead I get an error (missing dependency). -

Django how to use annotate with ManyToManyfield?

How to "force" the sharing the model instances between objects in django, when using prefetch_related()?
My question is: How to "force" the model instances to be shared? From output example below, Line 3 and Line 5 have Person(2) with different object instance ids. This means, there are 2 model instances of the same object, referenced from 2 different locations I would like to have them pointing to the exact same object instance. This way, there would be only 1 model instance of each object, referenced from multiple different locations Also, when a field is updated (for example, p2.name = 'p_two'), I would like to have it "visible" either by accessing the Person2 through any of Group12 or Group23, without the need to save and fetch data again. No need to save the model's state into database at this point. Documentation says: https://docs.djangoproject.com/en/4.1/ref/models/querysets/#:~:text=One%20difference%20to,and%20CPU%20time. Example of: models.py class Person(models.Model): name = models.CharField(max_length=128) def __str__(self): return f'<{hex(id(self))} P({self.pk}) {self.name}>' class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField(to=Person, through='Membership') def __str__(self): return f'<{hex(id(self))} G({self.pk}) {self.name}>' class Membership(models.Model): person = models.ForeignKey(to=Person, on_delete=models.CASCADE) group = models.ForeignKey(to=Group, on_delete=models.CASCADE) member_nickname = models.CharField(max_length=128) def __str__(self): return f'<{hex(id(self))} M({self.pk}) of {self.person} in {self.group}>' Example of tests.py class MyTests(TestCase): def test_object_ids(self): p1 = Person.objects.create(name='person1') p2 = Person.objects.create(name='person2') p3 = Person.objects.create(name='person3') g12 = Group.objects.create(name='group1') g23 = Group.objects.create(name='group2') … -
Django add multiple forms with dynamic fields and foreign key constraint to one page

Can I combine two querysets when one has a rank annotation and the other doesn't?
I am trying to write a search feature and can't figure out how to combine the results of a rank-annotated search and a non-rank-annotated search. Let's say I have the following model: class Song(models.Model): filename=models.CharField(max_length=120, db_index=True) title=models.CharField(max_length=120, db_index=True) title_vector=SearchVectorField(null=True, blank=True) I would like to let the user enter a single search term and search both title and filename. So if a user enters "space" as a search term, it should search for any song that has space in the title or filename. The query on the title vector looks like this. The idea is to order the results by rank so I can put the most relevant search results at the top. title_query_results = Song.objects.annotate( rank=SearchRank(F('title_vector'), query) ).filter( title_vector=query ) However, the filename query looks like this: file_query_results = Song.objects.filter( filename__icontains=query ) Because the file query results do not contain the rank annotation, I can't do a union on the results, because they have a different number of columns. Is there a way to get rank annotation for a query on the filename column? If not, what are my options for doing a union on the search results? For example, if I just wanted all the filename results to appear … -

I also have a forloop counter for each row, but after a new order item is added, the counter doesn't update dynamically, only after the page refresh. The related (I think) code: order-create-update.html: {% extends 'partials/base.html' %} {% block content %} <style> .orderitem-form { border-bottom: 1px solid black; } </style> <div class="container-fluid" style="margin-top:80px"> {% include 'orders/order_form_full.html' %} <hr> <div class="row" style="margin-bottom:5px; border-bottom-style:solid; border-bottom-width:1px"> <div class="col-1" style="font-weight: bold">Item #</div> <div class="col-2" style="font-weight: bold">Material Category</div> <div class="col-2" style="font-weight: bold">Material Subcategory</div> <div class="col-4" style="font-weight: bold">Material</div> <div class="col-1" style="font-weight: bold">Quantity</div> <div class="col-1" style="font-weight: bold">Price/Unit</div> <div class="col-1" style="font-weight: bold">Action</div> </div> {% for orderitem in object.get_orderitems_children %} {% include "orders/order_item_inline.html" with object=orderitem %} {% endfor %} {% if new_orderitem_url %} <div id="orderitem-create"></div> {% endif %} <button type="button" class="btn btn-secondary" hx-get="{{ new_orderitem_url }}" hx-trigger="click" hx-target="#orderitem-create" hx-swap="beforeend">Add order item</button> </div> {% endblock %} order_item_inline.html: <div id="orderitem-{{ object.id }}"> <div class="row mt-1"> <div class="col-1">{{ forloop.counter }}</div> <div class="col-2">{{ object.material_category }}</div> <div class="col-2">{{ object.material_subcategory }}</div> <div class="col-4">{{ object.material }}</div> <div class="col-1">{{ object.quantity_ordered }}</div> <div class="col-1">{{ object.material.price }}</div> <div class="col-1"> <button type="button" class="btn btn-secondary … -

How to preserve database table between tests in django?
How to preserve the database entries between tests in Django testing? python3 manage.py test tests --keepdb --keepdb preserves the database but not the table. The tables get flushed between the tests. Here is pseudo-code from django.test import TestCase class test_1(TestCase): def function_1(self): # Creates an entry in the database with file_path someModel.objects.create(file_path=file_path) class test_2(TestCase): def function_1(self): # needs the file_path to execute this function someModel.objects.get(file_path=file_path) <- this returns error since someModel does not have anything # Creates an entry in the database file_path_2 How can I preserve the database table between the tests so they can find the file path? This (talks about preserving the actual database and not the table) and this (creating a chain setUp does not work if I have 100´s tests that are chained) do not cover it.
