Page not found (404) appears when performing tutorial
I get the following error after many tries Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/polls Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order: admin/ The current path, polls, didn’t match any of these.

Validation error doesn't render on the template with 2 form
I have in my template with a form in which data is collected in 2 Django forms but sent to the view in the same post like this: <form> {{ form1 }} {{ form2 }} </form> The data is collected in the view and validated. To validate, I have validations declared in both forms. In case the validations fail because the data is incorrect, they return a raise (depending on which one or ones have failed). This raise is what should be shown on the screen to the user as an error. If the failed validation is in the second form, it displays the error correctly and without problems. Now, in the case that the failure is in the first form, the page simply reloads and does not show the error. The data already entered in the form is not lost and can be corrected, but the error is not displayed. My view is something like this: def create(request): form1 = Form1(request.POST or None) form2 = formset_factory(Form2, extra=0) form2Set = form2(request.POST or None, prefix='participant') context = { 'form1': form1, 'form2Set': form2Set, } if request.method == 'POST': if form1.is_valid() and form2Set.is_valid(): # Logic else: context['form1'] = form1 context['form2Set'] = form2Set return … -

What is the best approach to preserve GET parameters in django?
I have a ListView which I display using HTML <table> element. Each column is a field on model, while each row is a particular model instance. For this view I implemented search over multiple model fields (via GET form with query parameter search), filtering for each model field (via GET forms with query parameters filter--{{ field.name }}-{{ filter-type }}) and ordering over multiple fields (via query parameter order). I am planning to add pagination and ability for user to set page size (so soon two more query parameters). My question is: is there a simple approach to handle preserving existing unchanged GET values in both anchors and GET forms? For context: All three can be active at the same time, so paths can look like all of: /example/ /example/?filter--service_expires_at-datetime_from=2024-02-27T09%3A31&filter--service_expires_at-datetime_to= /example/?filter--username-icontains=abc&search=test /example/?order=-username,service_expires_at&search=test&filter--username-icontains=abc Search and filters have both links (to clear search or particular filter) and GET forms (to set search or particular filter). Order has links, which modify order GET parameter to either add ASC or DESC sort (or remove both) over particular column. My problem is that preserving GET parameters got quite cumbersome - for example, when I want to change order value, I need to take care to preserve … -

Package Django app without moving it to an external folder
We are working in a Django project with many applications. Our idea is to package them individually to use in other projects (like plugins). Is there any way to package an application without moving it to an external folder (like documentation explains)? We tried to add a setup.py file inside app folder and run python setup.py sdist. The command creates the dist/ and .egg-info/ folders, but then when we install the tar.gz in a new Django project using pip, it seems that the package itself is not installed, but only the .egg-info folder. Our current folder structure is: project/ app/ __init__.py admin.py apps.py models.py serializers.py setup.py tests.py urls.py views.py ... manage.py requirements.txt -

I am trying to sum all hours the user spent per day. I used this line of code: from django.db.models import F, Sum from django.db.models.functions import TruncDate Clocking.objects.filter(clockout__isnull=False, user=nid).values(date=TruncDate('clockin')).annotate(total=Sum(F('clockout') - F('clockin'))).order_by('clockin')) I have this result which calculates the hours into seconds. But if the user is clocking n times per day, how can I sum those hours or seconds in one date? <QuerySet [{'date': datetime.date(2024, 5, 7), 'total': datetime.timedelta(seconds=14418)}, {'date': datetime.date(2024, 5, 7), 'total': datetime.timedelta(seconds=9)}, {'date': datetime.date(2024, 5, 8), 'total': datetime.timedelta(seconds=9)}, {'date': datetime.date(2024, 5, 8), 'total': datetime.timedelta(seconds=3609)}]> -
Django `db_table` not renaming table
This question is (surprisingly) unlike similar ones, which ask about doing this dynamically, or ask how to do it in the first place. This question regards those suggestions not working as expected. Brief summary of situation: We made a series of Django apps as part of an API used in a real web app. We named those apps in ways that made sense at the time, e.g., "organizations" and "authentication". Now, we are packaging these apps as a distributable library, so a third party can install our apps in their API. The client already has apps named "organizations" and "authentication", causing conflicts (because Django apps must have unique names). Because we are creating the reusable library, we are renaming our apps from organizations to mycompany_organizations with corresponding model renames from Organization to MyCompanyOrganization to make them unique and distinguishable. I have made a series of migrations following this guide to create a new app and move the models over without losing data. Everything worked until someone added a new app that referenced our Organization (now named MyCompanyOrganization) model. This migration results in relation my_company_orgaanization does not exist, despite multiple foreign keys already pointing to my_company_organizations.organization and working fine. I inspected … -
Django: ModuleNotFoundError: No module named 'dotenv'
I see hundreds with this issue, but the answers to other posts aren't working for me. I'm simply trying to use dotenv and an .env file to hide sensitive data like an email password. I've tried this and it didn't work: pip uninstall dotenv pip uninstall python-dotenv pip install python-dotenv Error Traceback: Traceback (most recent call last): File "C:\PythonProjects\VoterSay7\venv\lib\site- packages\django\core\management\base.py", line 412, in run_from_argv self.execute(*args, **cmd_options) File "C:\PythonProjects\VoterSay7\venv\lib\site- packages\django\core\management\commands\runserver.py", line 74, in execute super().execute(*args, **options) File "C:\PythonProjects\VoterSay7\venv\lib\site- packages\django\core\management\base.py", line 458, in execute output = self.handle(*args, **options) File "C:\PythonProjects\VoterSay7\venv\lib\site- packages\django\core\management\commands\runserver.py", line 81, in handle if not settings.DEBUG and not settings.ALLOWED_HOSTS: File "C:\PythonProjects\VoterSay7\venv\lib\site- packages\django\conf\__init__.py", line 102, in __getattr__ self._setup(name) File "C:\PythonProjects\VoterSay7\venv\lib\site- packages\django\conf\__init__.py", line 89, in _setup self._wrapped = Settings(settings_module) File "C:\PythonProjects\VoterSay7\venv\lib\site- packages\django\conf\__init__.py", line 217, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1030, in _ gcd_import File "<frozen importlib._bootstrap>", line 1007, in _ find_and_load File "<frozen importlib._bootstrap>", line 986, in _ find_and_load_unlocked File "<frozen importlib._bootstrap>", line 680, in _ load_unlocked File "<frozen importlib._bootstrap_external>", line 850, in exec_module File "<frozen importlib._bootstrap>", line 228, in _ call_with_frames_removed File "C:\Users\mattk\Box\WeConsent\VoterSay10\settings.py", line 14, in <module> import dotenv ModuleNotFoundError: No module named 'dotenv' from settings.py: import dotenv from dotenv import load_dotenv
