# Create your models here.
from simple_history.models import HistoricalRecords
class TransactionType(models.TextChoices):
CASH_IN = 'IN', _('Cash In')
CASH_OUT = 'OUT', _('Cash Out')
class TransactionMethod(models.TextChoices):
STUDENT_TR = 'STT', _('Student Transaction')
BANK_TR = 'BKT', _('Bank Transaction')
SCHOOL_TR = 'SLT', _('School Transaction')
Teacher_TR = 'TRT', _('Teacher Transaction')
DONATE_TR = 'DET', _('Donate Transaction')
class Payment(models.Model):
id = models.AutoField(primary_key=True)
created_by = models.ForeignKey(settings.AUTH_USER_MODEL,
on_delete=models.PROTECT,
related_name="created_by")
updated_by = models.ForeignKey(settings.AUTH_USER_MODEL,
on_delete=models.PROTECT,
related_name="updated_by")
transaction_amount = models.FloatField("Transaction amount")
transaction_type = models.CharField(max_length=3,
choices=TransactionType.choices, default=TransactionType.CASH_IN,)
transaction_method = models.CharField(max_length=3,
choices=TransactionMethod.choices, default=TransactionMethod.STUDENT_TR,)
