Abstract countdown timer model to use in your Django projects.

Project description

About

The goal of this library is to allow you to inherit an abstract model in your model and turn it into a countdown time with pause and resume capability.

Simply import, inherit and your model is now a timer without worrying about the complexity involved in timekeeping.

This library is written to return the countdown value based on timestamps and thus does not require complicated background tick processes.

Minimum Requirements

  • Python 3.7
  • Django 3.0.7

Installation

Run the following in your project.

pip install django-countdowntimer-model

In your settings.p file please add:

INSTALLED_APPS = [
    # ...
    "countdowntimer_model",
    # ...
]

Usage

First you must import the abstraction into your model file.

from countdowntimer_model.models import CountdownTimer

Afterwords your model must inherit the abstraction.

class DoomsdayCountdownTimer(CountdownTimer):
    # ...

When you create your model, it is essential you set the duration_in_minutes and state fields. Afterwords the model will handle the rest. Please note if you want to override to use a custom timezone then you can set the timezone_override field.

doomsday_timer = DoomsdayCountdownTimer.object.create(
    duration_in_minutes=123,
    state=DoomsdayCountdownTimer.STATE.RUNNING,
)

Now that the object has been created you can get the latest countdown by running the following:

remaining_t = doomsday_timer.remaining_time() # // Returned in `time` format.

or

remaining_minutes = doomsday_timer.remaining_time_in_minutes() # // Returned in `integer` format.
