Bootcamp: Installing in windows

This error takes place when django==2.0, at this moment Bootcamp is not compatible with that version of Django. Please remove it and install a previous version, django==1.11.x works correctly.

Good morning @sebastian-code ,

I have downgrage the django, but now I have this error:

django.db.utils.OperationalError: unable to open database file

Hi @Allan-Nava it appears you have issues with your database and the server is unable to establish connection with the data volume, how are you doing that part?

Hi @sebastian-code, is my first django app with my personal pc windows. What should I do?

It depends how you work with databases. Personally I use Docker, but you could use a local instance of PostgreSQL, perhaps mount a networked DB server, or a VM of some sorts. There is also the easier option than is using SQLite locally.

I want to try use SQLite Locally

For that define the DATABASE_URL variable inside your .env file with a properly formated SQLite database address using URL format. You can find an example inside the env.example file.

I use the .env with the same conf:

# PostgreSQL conf
# POSTGRES_PASSWORD=mysecretpass
# POSTGRES_USER=my_super_user
# POSTGRES_DB=bootcamp
# DATABASE_URL=postgresql://my_super_user:[email protected]:5432/bootcamp

# Main environmental variables
DEBUG=True
SECRET_KEY=s3cr3t_key
ALLOWED_HOSTS=*
# URL to have SQLite example and to pass TravisCI
DATABASE_URL=sqlite:////bootcamp/db.sqlite3
# URL for Redis
# REDIS_URL=redis://redis_ip_address:port

I have the same error:

That is because the address is the wrong way. For SQLite, Django requires the physical location for the SQLite file inside your hard drive, expressed in URI format.

@sebastian-code Thank's, it works!

How do you use django 1.11 with this command pip install -U -r requirements/local.txt

I solved thanks!

@sebastian-code I have django 2.x in pip cache. Now how I can force pip to use django 1.9 while running this command pip install -U -r requirements/local.txt

Hi @jackengine The easiest way is to execute the command, and once installed, manually delete the package, and then install django again, but declaring the specific versión you want. My advice would be not going with django v1.9, is too old, I would suggest to use django 1.11 which is LTS.
