AttributeError: 'DatabaseWrapper' object has no attribute 'set_schema'

[emilany]

Hello. I followed what was stated in the installation docs but have come across this:

File "/Users/user/virtualenvs/hrmod/lib/python2.7/site-packages/django/db/__init__.py", line 33, in __getattr__
    return getattr(connections[DEFAULT_DB_ALIAS], item)
AttributeError: 'DatabaseWrapper' object has no attribute 'set_schema'

I have set the db engine as well. 'ENGINE': 'tenant_schemas.postgresql_backend',

I am running on django 1.11. What could possibly be the problem? Thank you.

@emilany, Did you ever figure this out? I'm having the same issue.

For anyone receiving this error: My solution was finding a leftover DATABASES/ENGINE assignment pointing to the standard PostgreSQL backend in a separate settings.py file that was being imported (develop vs production). Once I removed the second DATABASES definition, the error was gone.

When I debug the 'makemigrations customer' command it works fine, creates the migrations. When I execute the 'makemigrations' command with python manage.py makemigrations customer from the command line, I get DatabaseWrapper has no attribute schema_name.

I need to replace tenant model with static json data. Is that possible. The reason is i don't want to handle any database. I am going to use third party api. so when i try to command tenant model in settings and do migrate schemas i got 'critical error: Tenant model should set'. Than i called my data.json file in tenant model of settings file like this 'TENANT_MODEL = "app.data" '. when i try to migrate schemas i got the following error.

[bhuwanpaudelofficial]

i used this

DB_ENGINE=django.db.backends.postgresql

then i got the this error connection.set_schema(schema_name, tenant_type=tenant_type, include_public=False) ^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'DatabaseWrapper' object has no attribute 'set_schema' then i update the the database engine

DB_ENGINE=django_tenants.postgresql_backend

then this problem is solve by updating the code
