How to send extra parameter to unittest's side_effect in Python?
I'm using side_effect for dynamic mocking in unittest. This is the code. // main functionn from api import get_users_from_api def get_users(user_ids): for user_id in user_ids: res = get_users_from_api(user_id) // test script def get_dynamic_users_mock(user_id): mock_by_user_id = { 1: { "id": 1, "first_name": "John", "last_name": "Doe", ... }, 2: { "id": 2, "first_name": "Jane", "last_name": "Smith", ... }, ... } return mock_by_user_id[user_id] @patch("api.get_users_from_api") def test_get_users(self, mock_get_users) user_ids = [1, 2, 3] mock_get_users.side_effect = get_dynamic_users_mock # mock get_users_from_api get_users(user_ids) # call main function I want to send extra parameter from test_get_users to this get_dynamic_users_mock function.

How to change the background color of an input field of a Django form if it contains errors
I'm trying to code a form with fields that, if a user inputs data that doesn't pass the validation of the form, change their background colors from the default white to lightcoral. Here is a fragment of the HTML file that contains the form itself: <div id="div_formbox"> <form method="post" id="form_appointments"> {% csrf_token %} {{ form.non_field_errors }} <div class="input_group"> <div class="input_field {% if form.name.errors %}error{% endif %}"> {{ form.name}} </div> <div class="input_field {% if form.last_name.errors %}error{% endif %}"> {{ form.last_name }} </div> <div class="input_field {% if form.email.errors %}error{% endif %}"> {{ form.email }} </div> </div> <button type="submit">Send</button> </form> </div> And here is the part of the CSS file where I try to apply the color change to the input fields with errors: .error { background-color: lightcoral; } As you can see, I'm using Django tags to change the class of the form fields with errors from "input_field" to "error". Next, in the CSS file, I reference the "error" class to apply the styling I want. But it doesn't work. I've tried a bunch of variations but none have worked. I'm out of ideas. -
Celery server not terminating immediately when using prefork and without pool line command
I'm working on a django project with celery and redis installed. When I run the Celery server as 'celery -A main_proj -l debug -P solo' or 'celery -A main_proj -l debug -P threads', I can terminate them just fine by just pressing CTRL-C once or twice for warm/cold shutdown. However, when I run Celery as 'celery -A main_proj -l debug' and 'celery -A main_proj -l debug -P prefork', whenever I try to terminate them, it just get stuck at Worker: Stopping Pool. No matter how long I wait, it stays like that until I decide to terminate it with taskkill. I'm fine with the first two alternatives but I want to know why the latter options don't finish quickly. This is the code I have for my celery app: from __future__ import absolute_import, unicode_literals import os from celery.schedules import crontab from celery import Celery os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'main_proj.settings') app = Celery('main_proj') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks() Additionally, withing the settings.py file I set the CELERY_BROKER_URL with a redis URL that I get from Railway and I have the following code within the init file for the main_proj folder: from .celery import app as celery_app __all__ = ('celery_app',) This is what always happens whenever I … -
subdomain routing in django application
I have a django project that's hosted on a custom domain (e.g. mydomain.com). I have "app" app. For example, in development, requests looked like mydomain.com/app/dashboard. However, I wanted to use a subdomain instead so that my entire app is hosted on the subdomain app.mydomain.com and requests to mydomain.com/app/dashboard would route to app.mydomain.com/dashboard. I am using Nginx to handle this but I'm running into a few problems. Main part of nginx config: server { listen 443 ssl; server_name mydomain.co www.mydomain.co; location ~ ^/app(/?)(.*)$ { return 301 https://app.mydomain.co/$2; } location ~ ^/help(/?)(.*)$ { return 301 https://help.mydomain.co/$2; } location / { proxy_pass http://127.0.0.1:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; # WebSocket specific headers proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; } } server { listen 443 ssl http2; server_name app.mydomain.co; location / { # Proxy to your Django application server proxy_pass http://127.0.0.1:8000; # Adjust the port to match your setup proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } } # same for help When my url pattern is like this: path('app', include('app.urls')), and I try to access the dashboard it redirects to app.mydomain.com/dashboard which is not valid since /dashboard is a url exclusively … -

Best method to model django database using through table to access associations by date
Looking for advice on a tidy solution for accessing The end result I am looking for is the following report: cast, start_date, wire, winch I currently run a script when a cast object is submitted via form to get the active wire associated with the cast, and save it in the 'wire' foreign key field. The active wire is accessed in the script through property tags. Technically this information is retained in the database through a series of models associating a cast with a wire (Cast-DrumLocation-WireDrum), and the date fields that store when the events occurred. These events update the association between cast and wire. Is the way I modelled this a proper solution?, or is there another solutions where the wire foreign key does not need to be stored as a field in the cast model. class Cast(models.Model): id = models.AutoField(db_column='Id', primary_key=True) startdate = models.DateTimeField(db_column='StartDate') enddate = models.DateTimeField(db_column='EndDate') wire = models.ForeignKey('Wire', models.DO_NOTHING, db_column='WireId') winch = models.ForeignKey('Winch', models.DO_NOTHING, db_column='WinchId') class Drum(models.Model): id = models.AutoField(db_column='Id', primary_key=True\) location = models.ManyToManyField(Location, through='DrumLocation', related_name='active_location') material = models.TextField(db_column='Material') wiretype = models.TextField(db_column='WireType') class Winch(models.Model): id = models.AutoField(db_column='Id', primary_key=True) name = models.TextField(db_column='Name') drums = models.ManyToManyField(Drum, through='Drumlocation', related_name='active_drum') class Wire(models.Model): id = models.AutoField(db_column='Id', primary_key=True) nsfid = models.TextField(db_column='NsfId') drums … -

Best way for grouping models by two week periods and tie them to a data entry?
I am working on a project that is based on a two week time period. I have a model with a start_date and end_date as seen below: class CreateNewTimesheet(models.Model): employee = models.ForeignKey(Employee, on_delete=models.CASCADE) start_date = models.DateField(_("Start Date")) end_date = models.DateField(_("End Date")) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) I want to be able to add another line or something that groups the start_date and end_date. Dates: 03/06/2024 - 03/16/2024 And group or tie that to "week 1". The purpose behind this is to create a timesheet based on a two week time period. I need to be able to group the timesheets by a two week period and tie them to that specific group. All of the Timesheets need to be stored. After start_date and end_date are entered I need them to be tied to week one. I was thinking about adding another line to the CreateNew model and then tie that to week one. And then each start_date and end_date are entered, a new "week" is entered for each new start_date and end_date is created. Should that be based off of created_at entry? Should each week be grouped by a new url? I am honestly stuck at this point about … -

How to get the foreign key value into href attribute of a hyperlink element as a url parameter in Django template
I have data table showing list of vehicles from the Vehicle model with Driver column. When user clicking on the Driver column value, I want to redirect the user to driver detail page url driver-detail/license_number. I tried to pass the license_number to href attribute of hyperlink element like href="{% url 'driver-detail' vehicle.driver.license_number %}". This does not help me, it's always empty. If I omit the license_number in the href value it will pass the __str__(self) return value of the Driver model, which is combination of license_number and fullname. If I change the return value of __str__(self) in the Driver model it will work. But I don't want to change the return value of __str__(self). Any help is much appreciated!

Django PasswordResetView not working properly with app_name causing DisallowedRedirect
I'm encountering an issue with Django's built-in password reset functionality within my project. Specifically, I have an app named 'user' and I've defined the app_name variable in my urls.py as app_name = 'user'. However, this seems to be causing problems with Django's password reset views. Initially, I encountered the "Reverse for 'url name' not found" error when using auth_views.PasswordResetView. To address this, I tried setting the success_url parameter to 'user:password_reset_done' and providing a custom email_template_name. However, now I'm facing a new issue where the debugger is raising a DisallowedRedirect exception with the message "Unsafe redirect to URL with protocol 'user'" when attempting to access the password reset functionality. This occurs during the execution of django.contrib.auth.views.PasswordResetView. the error is: Unsafe redirect to URL with protocol 'user' Request Method: POST Request URL: http://127.0.0.1:8000/accounts/reset_password/ Django Version: 5.0.2 Exception Type: DisallowedRedirect Exception Value: Unsafe redirect to URL with protocol 'user' Raised during: django.contrib.auth.views.PasswordResetView Here's a summary of my setup: urls.py (within the 'user' app): from django.urls import path from django.contrib.auth import views as auth_views app_name = 'user' urlpatterns = [ path('reset_password/', auth_views.PasswordResetView.as_view(template_name='registration/reset_password.html', success_url='user:password_reset_done', email_template_name='registration/password_reset_email.html'), name="reset_password"), path('reset_password_sent/', auth_views.PasswordResetDoneView.as_view(template_name='registration/password_reset_done.html'), name='password_reset_done'), path('reset/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(), name='password_reset_confirm'), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(), name='password_reset_complete') ] registration/reset_password.html: {% block content %} <h1>Password reset</h1> <p>Forgotten your … -

Query using reverse relationship or objects manager?
from .models import Comment user = request.user comments_1 = user.comment_set.all().count() comments_2 = Comment.objects.filter(user=user).count() Between comments_1 and comments_2, which one is faster? Can someone explain to me? Any help will be greatly appreciated. Thank you very much. I looked in Django Documentation Making queries, but does not really say about the difference in performance.
