How to test that anything in a django-accessed database has changed?
I'm refactoring some code and adding an atomic.transaction block. We have some code that performs auto-updates en-masse, after the atomic block. (It can't be in the atomic block, because it traverses some many-related tables, which requires queries since the ORM doesn't store the distinct relations.) According to my reading of the code, it seems impossible that any changes could occur, but having a test to prove it would be nice in case someone makes a bad code edit in the future. So how would I go about writing a test that proves nothing in the database has changed between the start of the test and the end of the test? The database is postgres. We currently have it configured for 2 databases (the database proper and a "validation" database which I'd created after we discovered the loading code had side-effects in dry-run mode. I'm in the middle of a refactor that has fixed the side-effects issue and I just added the atomic transaction block. So I would like to write a test like this: def test_no_side_effects_in_dry_run_mode(self): orig_db_state = self.get_db_state() # How do I write this? call_command( "load_animals_and_samples", animal_and_sample_table_filename=("data.xlsx"), dry_run=True, ) post_db_state = self.get_db_state() # How do I write this? self.assertNoDatabaseChange(orig_db_state, … -
Django ImproperlyConfigured
I'm fairly new to programming and I was learning Python by following the textbook No Starch Python. There is a chapter on Django and I followed the steps of the textbook. However, when I run the program: from django.db import models class Topic(models.Model): """A topic the user is learning about""" text = models.CharField(max_length=200) date_added = models.DateTimeField(auto_now_add=True) def __str__(self): """Return a string representation of the model.""" return self.text I will get this error message: Traceback (most recent call last): File "/Users/admin/learning_log2/learning_logs/models.py", line 4, in class Topic(models.Model): File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/django/db/models/base.py", line 127, in new app_config = apps.get_containing_app_config(module) File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/django/apps/registry.py", line 260, in get_containing_app_config self.check_apps_ready() File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/django/apps/registry.py", line 137, in check_apps_ready settings.INSTALLED_APPS File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/django/conf/init.py", line 92, in getattr self._setup(name) File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/django/conf/init.py", line 72, in _setup raise ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured.

Serializing Dict Field inside List : ValueError: Cannot assign "OrderedDict
I am expanding JSON data from my last question and trying to save it to the database.

NGINX Response Header missing Access-Control-Allow-Origin header when uWSGI - Djago application timesout
Our project is using the typical setup with a NGINX application gateway, uWSGI application container and a Django application. Django is configured using cors middleware and successfully handles requests from cross domains. However, one of our endpoints tars large files for download, which can take a significant amount of time. If it takes too long uWSGI times out and NGINX returns a response that lacks Access-Control-Allow-Origin header. We have increased uwsgi_connect_timeout and uwsgi_read_timeout values in the NGINX config to address most cases. Since, Django is handling cors and thus the Access-Control-Allow-Origin header, NGINX doesn't have those values to return to the client. Does anyone know what uWSGI or NGINX settings I need to get the correct headers? A simplified version of our nginx config: upstream results_uwsgi { server unix:///opt/app_manager/app_manager.sock; } server { listen 80; server_name \$hostname; return 301 https://\$host\$request_uri/; } server { listen 443 http2 ssl; listen [::]:443 http2 ssl; server_name \$hostname; charset utf-8; stub_status on; # adjust to taste client_max_body_size 75M; large_client_header_buffers 4 128k; location / { uwsgi_pass results_uwsgi; include uwsgi_params; } location /api { uwsgi_connect_timeout 10000s; uwsgi_read_timeout 10000s; sendfile on; uwsgi_pass results_uwsgi; include uwsgi_params; } } Our uWSGI configuration: [uwsgi] app_root = /opt/app_manager # emperor = /etc/uwsgi/vassals chdir … -
Is there an alternative to map() that doesn't return anything?
With the way that map() is designed it seems like it is intended to be used specifically when you are trying to return a list of modified things. I am wondering, is there an alternative to map() that is designed specifically for when you do not want to return whatever is being modified? I am currently working in a django project where I would like to set the initial value of a few fields if the instance already has data for these fields. Here is an example (note: I excluded some code not relevant to the discussion to keep it cleaner): class EquipmentStatusForm(forms.ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.init_field(["fk_user"]) def init_field(self, attr): if hasattr(self.instance, attr): if getattr(self.instance, attr) != "" and getattr(self.instance, attr) is not None: self.initial[attr] = getattr(self.instance, attr) Say I wanted to extend this to use a list of attrs rather than a single one, and then set the initial value of all of these. I don't need the results to be returned because I am not actively doing anything with these attrs after I modify them. Is there a built in alternative to map() designed for this? Or am I really just stuck using a for … -

How to use variables in django models.py, (DEFAULT properties of fields)
I would like that, when clicking on one of the companies below, a variable is stored (until the browser is closed) with the company's code.

FOR EXAMPLE: class Employee(models.Model): class Meta: db_table = 'employee' CompanyCode= models.IntegerField( null=False, blank=None, default = 'VARIABLE', db_column='CompanyCode' ) After being stored in the database, I need to make a query to show all tuples where CompanyCode is equal to a certain value.

How to assign HTML Form fields to DJANGO Model Forms without using ModelForm

How can I run Django on a subpath on Google Cloud Run with load balancer?
I'll preface by noting that I have a system set up using Google Cloud Run + Load Balancer + IAP to run a number of apps on https://example.com/app1, https://example.com/app2, etc, and up to now I've only deployed Streamlit apps this way. The load balancer is directing traffic to each app in Cloud Run according to subpath (/app1, ...), and I used the --server.baseUrlPath=app2 option of streamlit run with no problems. Now I'm trying to get a 'hello, world' Django 4.1.5 app running on https://example.com/directory, and I can't seem to get the routes right trying differing suggestions here, here, and here.

404 error when requesting a file that exists
I'm trying to deploy a Django project using a VPS - it uses Apache and mod_wsgi. (It works fine locally). My homepage is displayed, but no static file is found, leading to a goofy display. I have configured my static files this way : settings.py : STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' call in template : ` ` After that I ran collectstatic, which created a "static" folder on root, as expected. I have checked via SSH and FTP, it is there (see screenshot 1 : ), with the correct permissions. The URL to access it should then be : /static. But I get this 404 error, even though my explorer seems to look for the correct adress (see screenshot 2 : ) I have only basic academic knowledge on this topic, but I simply don't understand how can I get a 404 when requesting a file that seems to exist.

So, i have up and running Django server on localhost. There's is a Vue page, whick is authorized and able to fetch models data. If i inspect page, i see that img element have correctly resolved URL, and image exsists and can be loaded.
