Adding IntegerField along with multiselectField?
I've been using MultiSelectField to select multiple list items, but after selecting I want to add their quantity too? Like a solution to add IntegerField alongside with the multiselectfield?? -
Django App: Timezone issues when running my Heroku app?
I'm creating a scheduling app on Django. As per most recommendations on the topic, the appointments (in my Appointments model) are stored in UTC. So my settings.py are set to TIME_ZONE = 'UTC'.The app was working perfectly on my local environment, but when I deployed to Heroku I started having issues. To give you an example (in production): >>> heroku run bash >>> python manage.py shell >>> from datetime import datetime >>> datetime.now() datetime.datetime(2020, 3, 10, 17, 10, 10, 453536) Yet, on local, I get: datetime.datetime(2020, 3, 10, 13, 10, 10, 196794) I tried to solve the issue (ie, 4-hour difference) by changing the TZ config value of the app to my local time, like so: heroku config:add TZ='America/Toronto' No luck. Anyone understands why this is happening? Any suggestions on how to solve this? -
How to validate empty label of M2M field in ModelForm?
I have a ModelForm overridden to have an extra option "None for now". When submitting the form it returns the form (invalid form) with the validation error: "" is not a valid value.

What do "Stars" mean about a django package in djangopackages.org grids?
In djangopackages.org grids, it shows many aspects of different django packages. One of them is "Stars". Can't find any explanation on what that "Stars" mean or indicate. If it's a rating system, where does it come from & who makes that decision? Anyone has any idea? -

How to override ModelMultipleChoiceField to pass empty_label
I have a Model and ModelForm: class Question(models.Model): quiz = models.ManyToManyField( Quiz, blank=True) class MCQuestionForm(forms.ModelForm): quiz = forms.ModelMultipleChoiceField( queryset=None, required=False, empty_label="Something", widget=forms.CheckboxSelectMultiple, help_text='Which tests this question applies to.') class Meta: model = MCQuestion exclude = () def __init__(self, *args, **kwargs): self.user = (kwargs.pop('user', None)) super(MCQuestionForm, self).__init__(*args, **kwargs) super_role = self.user.role subs_id = self.user.subordinates.values_list('role', flat=True) sub_roles = EmployeeType.objects.filter(pk__in=subs_id) cats = Category.objects.filter(groups=super_role) | Category.objects.filter(groups__in=sub_roles) self.fields['quiz'].queryset = Quiz.objects.filter(category__in=cats) ..where I need to add an empty_label to the ModelMultipleChoiceField.

Save empty form field as None in Django

Deploying my first Django app to Heroku: Error message 'h12' status '503'
I'm working on my first app, and I've avoided having to ask any questions so far, but here we are at deployment. Here is my code: (Note: The majority of the program is in '/starWarsMeals/djangoStarWarsMeals/appStarWarsMeals/utils.py' and not 'models.py'. I didn't feel a database was my best choice for this app, as the 'swapi' API I am pulling data from may change. I figured it would be best to cache the results of the API vs. updating a database periodically.) https://github.com/RyanLegits/starWarsMeals I am trying to deploy my Django app to Heroku, but I get the following 'h12' error code: https://textuploader.com/16beh My suspicion is that the API calls at the beginning of the script in 'utils.py' are taking too long and causing Heroku to time out. However, I'd like a professional opinion before trying to refactor my code. Also, the last thing I changed in the app was setting the environment variables if that is helpful. I tried deploying to Python Anywhere just to see if I could find anymore information. I got the 'Something went wrong' page and related error log: https://textuploader.com/16bez Notes: I did make sure to change 'ALLOWED_HOSTS' in 'settings.py' for each attempted deploy. I tried setting it to … -
Using requests module with Django APITestCase and APIClient?

How do I create a table to keep track of occasional inventory status updates and how do I use in the django environment?
I have a table that has a list of all the devices that I have in my inventory. Occasionally an audit is performed and the database needs to be updated with the status of the devices (e.g. "Lost", "Found", etc.). For this example I'm just naming the audits "Audit 1" & "Audit 2" but there will be many more. In the past I would just add a new field to the device table for each audit, but I'm trying to make it so all can be done completely through the web ui. The following is an example of how I might do it through mysql. But in my new environment, I'm using django and don't have a clue on how to duplicate this. SELECT * FROM inventory_audit; +----+----------------+-----------+-----------+ | id | audit_phase_id | device_id | status_id | +----+----------------+-----------+-----------+ | 1 | 1 | 1 | 2 | | 2 | 1 | 5 | 2 | | 3 | 2 | 2 | 1 | | 4 | 2 | 5 | 1 | +----+----------------+-----------+-----------+ SELECT whole.device_id, l1.a1 AS "Audit 1", l2.a2 AS "Audit 2" FROM (SELECT device_id FROM inventory_audit GROUP BY device_id) AS whole LEFT JOIN (SELECT device_id,status_id AS … -

Django 'migration is applied before its dependency' when running any migration commands

Calling Django ORM queries from within an async function running in an event loop
[Setup] I am using Django 3.0 as a wsgi application. I need to run the coroutine (shown below) from a view. This runs within an asyncio eventloop. From this event loop/coroutine I need to fetch some objects in the database using Django's ORM but django throws the following exception: django.core.exceptions.SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async import asyncio import concurrent def get_users_from_db(): return User.objects.all() async def do_some_async_stuff(): executor = concurrent.futures.ThreadPoolExecutor(max_workers=3) loop = asyncio.get_event_loop() attachments = await loop.run_in_executor(executor, get_users_from_db) def view(request): task = LOOP.create_task(do_some_async_stuff) result = not LOOP.is_running() and LOOP.run_until_complete(task) I am not sure what I am doing wrong. As far as I understand Django's doc suggests I should be able to run synchronous tasks (like an ORM query) in a separate thread, but that still doesn't work. The interesting thing is, running the code locally using manage.py runserver works fine, however running it with `gunicorn --bind 127.0.0.1:8000 src.config.wsgi:application throws the above exception. -
