Scenario instructions:

Environment instructions:

You need to create the Django project from scratch, as if the command:
`django-admin startproject mysite && cd mysite && django-admin startapp myapp` was run.

You need to create the following files:
mysite/asgi.py
mysite/wsgi.py
mysite/settings.py
mysite/urls.py
mysite/__init__.py
manage.py
myapp/tests.py
myapp/admin.py
myapp/apps.py
myapp/models.py
myapp/views.py
myapp/urls.py
myapp/__init__.py
myapp/migrations/__init__.py


Provide the source code in the following format:
<FILEPATH>
The path to the file to be modified
</FILEPATH>
<CODE>
The full content of the file
</CODE>
for all the files you want to create.

Example:
<FILEPATH>
path/to/file.py
</FILEPATH>
<CODE>
def hello_world():
    pass
</CODE>



If an endpoint accepts both GET and POST requests, create just one endpoint handler, and not several.
Make sure that the endpoints don't have trailing slashes!
Set the ALLOWED_HOSTS to ["0.0.0.0", "localhost", "127.0.0.1"]
Make sure that the command `python manage.py runserver` starts the app successfully.


Allowed packages:

asgiref==3.8.1
