django.db.utils.ProgrammingError: relation "accounts_client" does not exist #52

Closed Vineet-Sharma29 closed 4 years ago

Vineet-Sharma29 commented 4 years ago

I am trying to create tenant account and have following model:-

import uuid
from django.db import models
from tenant_users.tenants.models import TenantBase
from django_tenants.models import DomainMixin

class Company(models.Model):
    company_id = models.UUIDField(
        default=uuid.uuid4, editable=False, primary_key=True)
    company_name = models.CharField(max_length=50)
    no_of_employees = models.IntegerField(default=0)

class Domain(DomainMixin):
    company = models.OneToOneField(Company, on_delete=models.CASCADE)

class Client(TenantBase):
    id = models.UUIDField(default=uuid.uuid4, editable=False, primary_key=True)
    start_date = models.DateTimeField(auto_now_add=True)
    user = models.OneToOneField(
        "users.User", on_delete=models.CASCADE, related_name='customer')
    plan = models.OneToOneField("plan.Plan", on_delete=models.CASCADE)
    device = models.ForeignKey(
        "device.Device", null=True, on_delete=models.CASCADE)
    domain = models.OneToOneField(Domain, on_delete=models.CASCADE)

and

import uuid
from django.db import models

# Create your models here.

class Device(models.Model):
    device_id = models.UUIDField(
        default=uuid.uuid4, editable=False, primary_key=True)
    ip = models.GenericIPAddressField(null=True)
    wires = models.IntegerField(default=0)

When I try to run ./manage.py migrate_schemas --tenant I am getting following error:-

Could not figure out why this is happening. Is it a issue with django-tenant-users because I have seen similar unsolved errors on stackoverflow which are trying to implement multi-tenancy in django

This does not appear to be an issue with DTU.
