Time residual function in Python
I have 2 fields in the database: confirmed_at and preparation_time I would like to get two simple functions that should return (a) the time residual and (b) the % of time remaining. This is my logic which I am trying to acheive: - when order is confirmed_at I update the database with datetime.now() and preparation_time is indicated in minutes and stored as integer (for example 5 min is stored as 5) - completed_time is confirmed_at + preparation_time - time_remaining is completed_time - now() - order status is completed_time / now() * 100 This are my functions but I cannot make it works def get_remaining_time(self): start_time = datetime(self.confirmed_at) end_time = (start_time + datetime.timedelta(0,self.preparation_time*60)).time() # days, seconds. return end_time - datetime.now() def get_order_status(self): end_time = (datetime(self.confirmed_at) + datetime.timedelta(0,self.preparation_time*60)).time() return end_time / datetime.now() * 100 Thank you for any help -

relation "django_migrations" already exists
I am using Django-tenant-schemas for assigning tenants to their own schema. I had a migration issue awhile back and now there is something residual left from the failed creation of a tenant on it's own schema. This schema is called tiger. To give an idea how it is set up; there is some data which is public and exists on the public schema (such as users and companies) but everything else is tenant specific and on its own schema. This is how I run migrations: (venv) david@clearpath:~/clearpath_project$ python manage.py migrate_schemas [standard:public] === Starting migration [standard:public] Operations to perform: [standard:public] Apply all migrations: admin, auth, categories, companies, contenttypes, employees, invite, memos, notifications, phone_verify, quiz, sessions, videos [standard:public] Running migrations: [standard:public] No migrations to apply.

Django admin site: how to get formfield_overrides to override models.CharField with choices
In models.py class AnnualReport(models.Model): SCRAPED = 'scraped' CHECKED = 'checked' CHECKED_AND_RESTATED = 'restated' STATUS_CHOICE = ( (SCRAPED, 'Scraped'), (CHECKED, 'Checked'), (CHECKED_AND_RESTATED, 'Restated'), ) status = models.CharField(max_length=20, choices=STATUS_CHOICE, default=CHECKED) I want to override the style in status's form field in admin site.

how to use class based views for a single page blog with pagination in django

Django: When form is submitted, auto-fill a field
I'm looking to auto-fill a field when I submit a form so it is identical to another field. I have a createView with a modelForm. The idea is the user writes his/hers name, which then when submitted fills out the display_name field as well. I know it's weird "why have two of the same", but it has a purpose. Here's my code - I'm guessing I need to create a context that gets the display_name and sets it to be equal to the name? views.py class CreateIdentity(CreateView): template_name = 'admin/CreateIdentity.html' model = Identity form_class = CreateIdentityForm queryset = Identity.objects.all() def get_context_data(self, **kwargs): context = super(CreateIdentity, self).get_context_data(**kwargs) context["user_id"] = User.objects.get(username=self.request.user) return context def form_valid(self, form): form.instance.user_id = self.request.user return super().form_valid(form) def get_success_url(self): return reverse_lazy("view_identity_created_with_slug", kwargs={'slug': self.object.slug}) models.py class Identity(models.Model): name = models.CharField(max_length=200, null=False) display_name = models.CharField(max_length=200) slug = models.SlugField(max_length=100) user_id = models.ForeignKey(User, db_column="username", on_delete=models.CASCADE, null=False) -
How to get Twilio worker for incoming calls using TaskRouter? - Django
I'm building a simple Django contact center app using Twilio, TaskRouter, Client JS SDK. I'm using the status_callback to save the calls log for each customer in db by listening to the request with complete status_callback_event. (not sure this is the best way but it does the job) How would you go about saving the worker who received the incoming call? For outgoing calls I'm passing the request.user in the url as a costume parameter and I'm getting it in the status_callback. For incoming calls I'm getting the ParentCallSid in the status_callback, I assume I can use it to fetch the client who handled the call through the Rest API. Am I doing the right thing here? is there a simpler way to get this done? -

Can I use {% static %} outside the base.html in Django?
I am a beginner in Django and i have setup a project with a base.html file along with the folder static/images/img.jpg. base.html is setup correctly. Everything works inside this file but i have another file called index.html in the templates folder. So, in other words in the base.html i can use the command {% static '/images/img. jpg' %} but in my index.html Django does not recognise the command. In the index.html I have already provided the required commands {% extends 'base.html' %} and {% load static %} Does this command work only in the base html? Do i need another command for files outside the base.html Thank You -
